P‐167: In‐Cell Sensors for Light‐Adaptive LCDs

In‐cell sensor technology applied in Liquid Crystal Displays (LCDs) panels are investigated to enable adaptive adjustment of screen brightness and color temperature based on ambient light, thereby enhancing the display performance of screens in various environments. By incorporating ambient light sensors (ALS) and color temperature sensors (CTS), which are compatible with the normal manufacturing process of LCD panels, TCL CSOT has achieved a technological upgrade compared to traditional LCDs technology. In‐cell ALS referred to a wide sensing range of 0~10000 lux and high resolution of 1 lux below 50 lux. In‐cell CTS showed an effective range of 3500~9000 K with detection accuracy of 800 K. With these sensors, LCDs panel can adaptively change its brightness and color temperature within different environments, leading to a new feature of TV, monitor and other commercial LCDs.
