Drive Thru Menu Board Brightness & IP Rating Specs: Selection Reference

In the procurement decision-making process for drive-thru menu boards, brightness and IP protection rating are two core metrics that are most easily misled by paper parameters but directly determine project success or failure. Many purchasers order based on the numbers in the specification sheet, only to find that the menu is illegible under midday sunlight, the equipment is prone to water ingress during the rainy season, or brightness degradation exceeds expectations after just one year of use. This article systematically dissects the selection logic, common pitfalls, and verification methods for these two parameters from a B2B project procurement perspective, helping foodservice brands and system integrators minimize risks during the selection phase。

Quick Answer: For direct sun drive-thru installations, specify 2,500+ nits typical brightness and IP65 front protection minimum. For canopy/partial shade, 2,000–2,500 nits suffice. Always verify sustained brightness (not peak), front-vs-full IP coverage, and operating temperature range before purchase.

1. Why Brightness and IP Are the Two Core Indicators for Outdoor Menu Board

The environment where outdoor drive-thru menu boards operate is entirely a different scale compared to indoor digital signage. They must simultaneously withstand midday direct sunlight, rainstorms, sandstorms, and extreme temperature fluctuations, while operating over 12 hours daily and running year-round without interruption. Among all hardware parameters, brightness determines whether customers can read the menu content, and the IP protection rating dictates whether the equipment can survive its first rainy season—these two are the baseline requirements for project success. Other parameters (resolution, contrast, interfaces) only become relevant once these two are met.

1.1 Sunlight Readability Basics

The core logic of Sunlight Readability is that the light emitted by the screen must be stronger than ambient light for the human eye to see the content clearly. The illuminance of indoor office environment is about 300-500 lux, and a standard monitor of 300-500 nits is sufficient; The illuminance of direct sunlight at noon outdoors can reach 50000-100000 lux, which is more than 100 times that of indoors. If the screen brightness is not enough, the image will look like a transparent film illuminated by strong light - the content will be "washed away" by ambient light, leaving only a gray white area.

The common judgment standard in the industry is that the screen brightness must be at least 2-3 times the ambient light reflection brightness to ensure basic readability. Based on the reflectivity of about 4% on the surface of ordinary glass, the reflection brightness of the screen surface can reach 4000 nits under 100000 lux of noon sunlight. Therefore, the output brightness of the screen itself needs to reach 2500 nits or more to form effective contrast, ensuring that the driver can clearly read menu text and prices in the car.

1.2 Why Nits Matter More Than Resolution Outdoors

Many buyers instinctively pursue high resolution when selecting, but in outdoor drive thru scenarios, brightness takes precedence over resolution. The reason is simple: a 4K screen with insufficient brightness cannot see the content clearly in sunlight, and the pixel density of 4K is completely wasted; A 1080P screen with sufficient brightness can at least ensure that every item in the menu is clear and readable, and customers can order normally.

In terms of viewing distance, the typical viewing distance for the drive thru menu board is between 3-10 meters. At this distance, the human eye's resolution is limited - the 55inch 1080P screen is 5 meters away, and the pixel density has exceeded the human eye's resolution limit. In other words, in a drive thru scenario, 'seeing' is much more important than 'seeing in detail'. When the budget is limited, prioritize spending money on brightness and protection instead of piling up resolution parameters. As a reference, the outdoor digital drive thru menu board supplier Clientop's product line comes standard with a brightness of 2500 nits, which is the benchmark value based on actual verification of a large number of projects.

2、 Brightness selection: How many nits correspond to what scene

Brightness is not necessarily better the higher - higher brightness means higher procurement costs, higher power consumption, and faster light decay. The purchaser needs to select a brightness level that is just sufficient and leaves a certain margin based on the actual lighting conditions of the installation location. The following is a scenario brightness correspondence based on industry experience summary, which can serve as a preliminary reference for project selection.

2.1 Brightness by Environment Type

The demand for brightness varies greatly among different installation environments. Roughly speaking, it can be divided into three categories: full direct sunlight, partial shading (under a canopy), and complete shading. But in actual projects, most drive thru sites are in a gray area between "partial shading" and "full direct sunlight" - such as having shading in the morning, being directly exposed to the sun in the afternoon, or having weak sunlight during the rainy season and strong sunlight during the dry season. Suggest selecting based on the worst-case scenario (the period with the strongest sunshine in a year) to avoid readability issues in specific seasons after selecting based on average conditions.

It should be noted that even in drive thru ordering areas with rain shelters, the reflected light from the surrounding environment (from the ground, roads, and surrounding buildings) is still quite strong. Don't assume that "indoor screens can be used with shading" - indoor screens with a brightness of 300-500 nits are not enough in any outdoor scene, even if there is a canopy covering them.

2.2 Direct Sun vs. Partial Shade vs. Full Canopy

In specific projects, it is recommended to make precise judgment based on the following three levels：

Direct Sun: The screen is exposed to direct sunlight for more than 4 hours a day. This scenario requires the selection of a high brightness outdoor screen with 2500 nits or more, and must be accompanied by anti-glare (AG) surface treatment. Otherwise, customers will be unable to read the menu during noon hours, which will directly affect ordering efficiency and average order value. For areas with strong sunlight, products with 3000-4000 nits can provide more ample margin and longer effective service life.

Partial Shade: There is a canopy or building overhang above the screen, but there is still sunlight on the side or during morning and evening hours. This is a typical environment for most drive thru. Recommend choosing a product with 2000-2500 nits and confirm that the product comes with an ambient light sensor and automatic brightness adjustment function - ensuring readability at full brightness during the day, and automatically reducing brightness at night to reduce light pollution and power consumption. The 43inch drive thru menu board for commercial projects by the Client covers this brightness range and is the mainstream choice for small lanes and convenience store scenes.

Full Canopy: The screen is completely surrounded by the building, with only scattered light and no direct sunlight. This scenario is relatively rare in drive thru (often seen in indoor ordering channels). 1000-1500 nits is usually sufficient, but it is still necessary to confirm the temperature and humidity tolerance of the equipment, as full shading does not mean no temperature and humidity challenges.

3、 Pits in brightness parameters: peak brightness vs typical brightness vs lifetime brightness

'High brightness' is the most common word on the supplier's promotional page, but it is also the easiest parameter to fill with water. The actual performance of two products labeled with "2500 nits" may differ significantly. As the purchaser, it is necessary to clarify the three different definitions of brightness and which one is the supplier's trademark.

3.1 Peak vs. Typical vs. Rated Brightness

At present, there are at least three ways to express brightness in the industry, with a numerical difference of up to 30% -50%：

Peak Brightness: The highest brightness that a screen can achieve under specific conditions (usually full white image, maximum current, short time). This number looks the best, but it almost never appears in actual use - because a full white screen is not the norm for menus, and running at peak brightness for a long time can accelerate light decay and shorten lifespan. Some suppliers only label peak brightness and attract customers with a beautiful number, but the actual sustained brightness may only be 60% -70% of the peak.

Typical/Rated Brightness: The sustained output brightness of the screen under normal operating mode and standard test conditions. This is a more valuable indicator as it represents the performance of the device in actual use. In the official definition of ENERGY STAR, "Maximum Reported Luminance" refers to the manufacturer's nominal preset maximum brightness, while "Maximum Measured Luminance" is the maximum value that can be achieved through manual adjustment - the latter being higher but not necessarily sustainable. When purchasing, it is necessary to confirm that the supplier's trademark is for typical/rated brightness, not peak brightness.

Calibrated Brightness: Some professional manufacturers will perform brightness calibration on each device before leaving the factory to ensure the consistency of brightness among products in the same batch (usually with an error controlled within ± 5%). This parameter is important for projects involving multi screens splicing or unified image of multiple stores - if the brightness difference between two parallel screens exceeds 10%, the difference can be clearly seen by the human eye, affecting the brand image.

Procurement suggestion: During the inquiry stage, it is recommended to explicitly request suppliers to provide written explanations of the specific values and testing conditions for "typical/rated brightness" (test point location, proportion of all white screen, ambient temperature), rather than just accepting a vague description of "high brightness". At the same time, reference can be made to the labeling methods of industry giants - for example, Samsung's commercial LED products are labeled with both Max Brightness (calibrated) and Peak Brightness, and there is a significant difference between the two; LG's outdoor products are labeled with 4000 nits (Typ.) and 3200 nits (Min.), providing ranges for typical and minimum values, which are professional practices.

3.2 Brightness Degradation Over Time

Another easily overlooked issue is the decay of brightness over time. All LED backlit displays gradually darken over time, which is an inherent characteristic of LED devices. But the speed of attenuation varies greatly, directly affecting the effective service life of the product.

Generally speaking, the annual brightness attenuation rate of indoor display screens is about 5%, while outdoor display screens can experience an annual attenuation rate of 8% or even higher due to long-term exposure to ultraviolet radiation and high temperatures. This means that for an outdoor screen with a nominal capacity of 2500 nits, if the annual attenuation rate is 8%, the actual brightness after 3 years will only be about 2500 × (1-8%) ³ ≈ 1950 nits, and after 5 years it will be about 1650 nits - if the project is initially selected at 2000 nits, it may already be below the readability threshold after 3 years.

That's why we recommend leaving at least 20% -30% brightness margin when selecting. It may seem a bit expensive, but in reality, it ensures that the device always meets readability requirements throughout its 5-7 year lifecycle. Professional outdoor display manufacturers typically provide the "Lifespan to Half Brightness" parameter, which refers to the time required for LED brightness to decay to 50% of its initial value. Industry standards typically range from 50000 to 100000 hours. The 49 inch commercial drive thru menu display adopts industrial grade LED backlight and intelligent temperature control design, effectively delaying the speed of light decay and ensuring that the brightness can still meet outdoor readability requirements after long-term use.

4、 IP protection level: What does the number represent

Ingress Protection Rating is an internationally recognized standard for evaluating the protective capabilities of electronic device enclosures, developed by the International Electrotechnical Commission (IEC). The standard format is IP followed by two digits, with the first digit representing the dustproof level (0-6) and the second digit representing the waterproof level (0-9). The larger the digit, the higher the protection level. Understanding the meaning of these two numbers is the foundation for purchasing outdoor display screen.

4.1 IP Rating Explained (First Digit / Second Digit)

First digit - dustproof level：

• IP0X: Unprotected
• IP1X: prevents solids with a diameter ≥ 50mm from entering (such as palms)
• IP2X: Prevent solids with a diameter ≥5mm from entering (such as fingers)
• IP3X: prevents solids with a diameter of ≥5mm from entering (such as tools, wires)
• IP4X: Prevent solids with a diameter ≥0mm from entering (such as fine screws)
• IP5X: Dustproof - cannot completely prevent dust from entering, but the amount of entry does not affect the normal operation of the equipment
• IP6X: Dust tight - completely prevents dust from entering

Second digit - Waterproof rating：

• IPX0: Unprotected
• IPX1: Protection against vertical dripping (condensation)
• IPX2: Anti tilt 15 ° drip
• IPX3: Waterproof (within 60 ° of vertical direction)
• IPX4: splash proof (splash proof in any direction)
• IPX5: Waterproof spray (6.3mm nozzle low-pressure water column spray)
• IPX6: Anti strong water spray (12.5mm nozzle high-pressure water column spray)
• IPX7: Protection against short-term immersion (1 meter water depth, 30 minutes)
• IPX8: Anti continuous diving (deeper water pressure, longer duration, specific conditions defined by the manufacturer)
• IPX9K: Anti high temperature and high pressure spray (80 ° C hot water close range spray, DIN standard extended level)

4.2 Common IP Ratings for Drive-Thru Display

n the drive thru menu board category, common IP level configurations and their applicable scenarios are as follows：

As can be seen, IP65 is the mainstream entry-level level for outdoor menu boards. It can completely prevent dust from entering and resist low-pressure water jets from any direction - this basically covers common scenarios such as rainy days, car washing, and sprinkler trucks. For most drive thru projects, a configuration of IP65 on the front and IP55 on the back is sufficient, as the back usually faces the building or column and is not directly impacted by rainwater. This design ensures reliable protection while controlling costs. The 55 inch drive thru menu board for enterprise projects adopts a protective architecture of IP65 on the front and IP55 on the back, which has been verified to be stable and reliable through a large number of practical projects.

5、 Common misconceptions about IP rating: IP65 does not necessarily mean waterproofing is enough

Many buyers think everything is fine when they see products labeled with IP65, but in actual projects, products labeled with the same IP rating may have significant differences in waterproof performance. Here are a few of the most common cognitive misconceptions.

5.1 Front Protection vs. Full Enclosure Protection

The first misconception is that "front IP65" is mistaken for "whole machine IP65". Many outdoor display products only have IP65 certification covering the front - that is, the screen face and front frame, while the protection level of the back, bottom, and interface areas may only be IP55 or even lower. For the drive thru menu board, the front is indeed the main direction facing rainwater impact, but the back and interface are also threatened by moisture, condensation, and splashing.

More importantly, some suppliers' IP certification only applies to the display panel itself and does not include the entire casing and interface. The panels from panel manufacturers such as LG and Samsung may have IP ratings, but after assembly, if the shell design, sealing process, and interface treatment are not in place, the actual protection capability of the entire machine will be greatly reduced. When purchasing, it is necessary to confirm whether IP certification is for the entire machine or only for the panel? Is the certification report testing the front or the entire machine?

For the drive thru project, our recommended standards are: the front must meet IP65, the back must be at least IP54 or above, and the interface area should have waterproof rubber rings or waterproof joints. If the project is located in areas with high rainfall or coastal high salt spray, consideration should be given to the overall IP65 or even IP66 configuration, as well as additional salt spray test reports. In the selection stage, you can first understand the industry standard protection requirements in the digital drive thru menu board definition, and then compare the actual configurations of different suppliers.

5.2 Temperature Cycling & Condensation Risk

The second and more hidden misconception is that IP rating only tests dust and water resistance under static conditions, and does not test temperature cycling and the resulting condensation problems. And condensation is precisely one of the most common reasons for the failure of outdoor display screens.

The principle is simple: when the internal temperature of the device changes rapidly (such as reaching 50-60 ° C after exposure to sunlight during the day, sudden drops in temperature in the evening, or sudden rain to cool down), if the air inside the device contains moisture, it will condense into water droplets on the surface of the circuit board and optical components. These condensates can cause problems such as circuit short circuits, corrosion, and display abnormalities - and IP level testing is conducted under constant temperature and humidity conditions, which cannot guarantee condensation protection under temperature cycling.

Professional outdoor display manufacturers will solve the condensation problem through the following methods: firstly, adopting a fully sealed design + desiccant to maintain absolute dryness inside; Secondly, a breathable valve (waterproof breathable membrane) design is adopted to balance the internal and external air pressure while blocking the entry of liquid water; Thirdly, a heating/temperature control system is adopted to increase the internal temperature at low temperatures to prevent condensation. When purchasing, don't just look at the IP rating numbers, ask the manufacturer for their solutions and testing data for condensation issues.

In addition, it should be noted that the IP rating does not cover indicators such as corrosion resistance, UV aging resistance, and impact resistance. Salt spray corrosion in coastal areas, strong ultraviolet radiation in high-altitude areas, and human impact damage are all beyond the range of IP65 pipes. A complete outdoor reliability assessment should include: IP protection level + operating temperature range + salt spray test + UV aging test + impact resistance level (IK level) to comprehensively evaluate the outdoor adaptability of the equipment.

6、 Other related parameters: working temperature, humidity, anti-glare

Brightness and IP protection are two core parameters, but to ensure long-term stable outdoor operation, several supporting parameters need to be considered. These parameters are coordinated with brightness and IP protection - for example, brightness may decrease at high temperatures, and IP sealing strips may harden and fail at low temperatures.

6.1 Operating Temperature Range

The working temperature range is a key indicator for measuring the adaptability of outdoor display screens. Indoor display screens typically operate within the range of 0-40 ° C, while outdoor display screens need to cover a wider temperature range. The working temperature range of mainstream outdoor screens in the industry is usually -30 ° C to 50 ° C or higher, and better quality products can reach -30 ° C to 70 ° C.

The impact of temperature on display screens is multifaceted: high temperatures accelerate LED light decay, shorten LCD lifespan, and accelerate internal component aging; Low temperature can cause slow LCD response, difficult startup, and delayed backlight illumination. For the drive thru menu board, the internal temperature of the screen when exposed to direct sunlight may be much higher than the ambient temperature - even if the ambient temperature is only 30 ° C, the surface of the screen may reach over 50 ° C in sunlight. That's why just looking at the ambient temperature range is not enough, it also depends on whether the product has temperature test data under direct sunlight.

The nominal operating temperature range of the drive thru menu board of the Client op is -30 ° C to 70 ° C. It adopts an intelligent temperature control system, which automatically starts the cooling strategy when the temperature is high and enables heating protection when the temperature is low, ensuring stable operation even in extreme weather conditions. For projects deployed in extremely cold or hot regions, it is recommended to confirm temperature parameters with suppliers during the selection phase and request corresponding temperature cycling test reports.

6.2 Anti-Glare & AR Coating

Relying solely on high brightness cannot completely solve the problem of outdoor readability, and the reflection on the screen surface can also seriously affect the reading experience. That's why anti-glare treatment is a standard feature of outdoor display screens. There are currently two main technological routes in the industry: AG (Anti-Glare) and AR (Anti Reflection).

AG treatment is the process of forming microstructures on glass surfaces through chemical etching or coating, converting specular reflection into diffuse reflection, thereby eliminating the "mirror" effect under strong light. The key parameter for AG processing is haze - the higher the haze, the stronger the anti-glare effect, but the transparency and clarity of the image will slightly decrease. Outdoor applications typically use AG treatment with medium to high haze (15% -30%) to achieve a balance between anti-glare and clarity.

AR anti reflection coating directly reduces the reflectivity of light through the interference effect of multi-layer optical films. High quality AR coating can reduce single-sided reflectivity from 4% to below 1% without affecting image clarity. However, the cost of AR coating is higher, and the wear resistance and weather resistance after long-term outdoor use need to be specially verified. For high-end outdoor projects, AG+AR composite treatment is the best solution, which can both prevent glare and reduce reflection.

When purchasing, it should be noted that many suppliers only mention "anti-glare" without specifying which technology, haze, or reflectivity it is. Suggest specifying requirements for specific indicators and test reports such as haze value (tested according to ASTM D1003 standard), total reflectance (normal incidence), transmittance, surface hardness (pencil hardness ≥ 4H), friction resistance test times, etc., instead of just accepting a vague "anti-glare" description. When comparing different technological approaches, one can refer to the analysis of the differences in anti-glare solutions under different display technologies in the article "LCD vs LED drive thru menu board technology".

7、 Our testing method: How to conduct environmental testing on the Client before it leaves the factory

As a manufacturer specializing in industrial grade outdoor display equipment, Clientop understands that the reliability of outdoor equipment is not achieved through advertising, but through testing and verification. Every drive thru menu board that leaves the factory must undergo multiple rounds of environmental testing and quality control inspections to ensure that the equipment arriving at the customer's site can operate stably in various extreme environments.

7.1 Our Environmental Test Protocol

The environment testing system of Clientop covers the entire process from components to the whole machine, ensuring that every link meets outdoor reliability standards：

1. High temperature aging test: The whole machine runs continuously for 48 hours in a high temperature environment of 60 ° C, monitoring brightness stability, power consumption changes, and functional integrity, simulating long-term high temperature operation scenarios in summer.
2. Low temperature startup test: After being placed in a low temperature environment of -30 ° C for 4 hours, turn on the machine to verify the low-temperature startup time, display effect, and whether the temperature control system is working properly.
3. Temperature cycle test: Conduct 50 cycles of temperature shock test between -30 ° C and+70 ° C, each cycle including four stages of high temperature holding, rapid cooling, low temperature holding, and rapid heating, to verify the reliability of sealing strips, circuit boards, and optical components under sudden temperature changes and verify the effectiveness of condensation protection design.
4. IP waterproof and dustproof testing: Conduct formal testing of IP65 (front) and IP55 (back) according to the IEC 60529 standard, including dust testing room testing and water spray testing, and randomly inspect each batch to ensure consistency.
5. Salt spray test: For projects in coastal areas, an additional 48 hours salt spray test (5% NaCl, 35 ° C) will be conducted to verify the corrosion resistance of metal components and surface coatings.
6. UV aging test: Simulate an outdoor UV irradiation environment and conduct a 200 hour UV accelerated aging test to verify the weather resistance of the shell material and surface treatment, and prevent yellowing and cracking after long-term use.

These tests are not just a superficial process, but rather a means to discover design flaws and optimize product reliability. The problems exposed in each round of testing will be fed back to the R&D department to drive product iteration and improvement. After ten years of experience in outdoor display manufacturing, the failure rate of Client op's products in the first year was controlled below 0.5%, far below the industry average level.

7.2 Quality Control Check

In addition to environmental testing, Client's quality control system also includes the following key steps：

• Incoming inspection: Full inspection of core components (panels, power supplies, driver boards) before entering the factory to ensure consistency of incoming materials
• Production process inspection: Each production line is equipped with dedicated QC, and spot checks are conducted according to the process nodes
• 48 hours whole machine aging: Each product is continuously powered on and operated for 48 hours before leaving the factory, and the operating status is monitored in real-time during the aging process
• Factory final inspection: Appearance, display effect, interface function, and brightness value are tested one by one, and any non-conforming products will never be released
• Batch consistency control: The brightness error of products in the same batch is controlled within ± 5% to ensure visual consistency during multi screens splicing and multi store deployment
• Certification system: The entire series of products have passed CE, FCC, UL, RoHS certifications, and the factory has passed ISO 9001 quality management system certification

For B2B procurement customers, these tests and quality controls mean lower after-sales costs, higher project success rates, and more stable long-term partnerships. If you have any requirements for testing details or customized testing in specific environments, you can directly contact our technical team to obtain detailed testing reports and plans.

8、 Quick Selection Comparison Table

For the convenience of quick decision-making by the purchaser, we have summarized the key selection points for brightness and IP protection of the drive thru menu board into the following comparison table. Can quickly locate the required parameter level based on the installation environment, budget, and expected lifespan of the project.

8.1 Quick Selection Guide

Selection suggestion: Do not blindly pursue the highest configuration, and do not choose the lowest configuration to save costs. The correct approach is to select the corresponding level according to the actual project environment and reserve about 20% margin in key parameters (brightness, IP). For the standardized deployment of chain brands, it is recommended to use the "standard level" as the benchmark configuration, and make targeted upgrades for individual store in special environment. This can ensure overall effectiveness and control overall procurement cost.

FAQ

Q1：What is the minimum brightness required for an outdoor drive thru menu board?

A：The minimum requirements vary depending on the installation environment. A minimum of 1500 nits is available for environments with complete canopy shelter, but not recommended; The standard drive thru scenario for partial shading requires a minimum of 2000 nits, with a recommended minimum of 2500 nits; A minimum of 2500 nits is recommended for outdoor environments with direct sunlight, with a recommended range of 3000-4000 nits. Note that these are typical/rated brightness, not peak brightness.

Q2：What is the difference between IP65 and IP66? Which one do I need to choose?

A：The waterproof rating of IP65 is "anti-low pressure water jet" (6.3mm nozzle), and IP66 is "anti-high pressure water jet" (12.5mm nozzle). In short, IP65 can prevent rainstorm and ordinary water gun washing, and IP66 can prevent high-pressure water gun and stronger waves/typhoons. For the vast majority of drive thru projects, IP65 (at least on the front) is already sufficient. If the project is located in a coastal area with frequent typhoons, requires frequent use of high-pressure water guns for cleaning, or if the screen installation position is particularly low and easily splashed by accumulated water, IP66 can be considered.

Q3：Why is there so much price difference among different manufacturers for the same IP65 standard?

A：Because IP65 is only a minimum passing standard, achieving and doing well are two different things. The difference may lie in whether it is IP65 for the front or the whole machine? Is it IP65 for the panel or IP65 for the entire machine? Is ordinary rubber strip or foam silicone/liquid adhesive used for sealing? Has the sealing reliability been verified under temperature cycling? Is there any condensation protection design? Is the waterproofing treatment in the interface area inadequate? These details do not affect the success or failure of IP authentication, but directly affect the actual service life. Suggest not only looking at IP rating numbers when purchasing, but also requesting detailed sealing design specifications and environmental testing reports.

Q4：Will the brightness decrease? How much brightness can it maintain in 3 years?

A：It will decay, which is an inherent characteristic of LED. The annual attenuation rate of outdoor display screens is usually between 5% and 8%, depending on the usage environment and temperature control design. Calculated at an annual decay rate of 8%, a screen with an initial capacity of 2500 nits will have approximately 1950 nits after 3 years and 1650 nits after 5 years. That's why it is recommended to reserve a brightness margin of 20% -30% when selecting. High quality products can control the annual decay rate at around 5% through high-quality LED beads, excellent heat dissipation design, and intelligent temperature control, significantly extending the effective service life.

Q5：Which is more important, anti-glare or high brightness?

A：Both are indispensable, but there is a priority order. High brightness is the foundation - if the brightness is not enough, even the best anti-glare treatment cannot make you see the content clearly in sunlight. Anti-glare is an amplifier - under the premise of meeting brightness standards, anti-glare treatment can significantly improve readability and eliminate mirror reflection. The correct combination is: high brightness (2500 nits+) +AG anti-glare surface treatment. When the budget is sufficient, it can be upgraded to AG+AR composite processing to further enhance the visual effect. Products that only emphasize high brightness or anti-glare are incomplete solutions.
