What Makes Clientop's Large E Ink Displays Different？

The core values of large-sized e-paper lie in low power consumption, strong readability, and easy customization - Client op brings these three things to commercial grade from the source

● Bistable Paper-Like Display, Near-Zero Power： E-paper is a bistable display: after the image is written, it no longer consumes power, and during static display, the power consumption approaches zero. For projects deployed in bulk (with dozens or even hundreds of large screens in one batch), the long-term electricity cost difference is significant, and public information screens that multiple people will continue to pay attention to are particularly cost-effective.
● Wide Format Range (25.3”–75”+), Custom Sizes：From 25.3 "entry-level screens, 31.5"/32 "mainstream commercial screens, 42" large-area displays, to 75 "+public information walls, non-standard sizes can be customized according to the project. The customer provides drawings or references, and we confirm the sample before mass production
● Sunlight-Readable & Wide Viewing Angle： E-paper is non reflective and remains clear and readable under strong light and direct sunlight, making it suitable for environments such as transportation hubs and outdoor information screens; Wide viewing angle, multiple people watching simultaneously without color cast
● Remote CMS / WiFi-4G Content Management：Support mobile app/4G/WiFi remote centralized content updates. Unified management of single or hundreds of screens, synchronized across multiple stores with one redesign, suitable for chain replication and cross site deployment projects

Commercial-Grade Quality & Testing

Commercial large screens are not considered qualified even if they can display - before leaving the factory, the Client op checks layer by layer according to commercial standards to ensure consistency and long-term stability of batch projects

● Factory Testing Protocol:

1. Screen and bad pixel detection: Factory inspection, screen by screen confirmation of no bad pixels, no color deviation, and uniform display

2. Low power verification: Tested standby power consumption after static writing, meets nominal specifications Temperature stability test: Continuously operate in a wide temperature environment to confirm the stability of 7 × 24 commercial scenarios.

3. Interface and refresh testing: Verify that the refresh timing, interface signal, and remote control are functioning properly

4. Appearance and consistency inspection: full inspection of dimensions, borders, silk screen printing, packaging, and batch shipment consistency
