Abstract
In this paper, we present a novel integrated light‐dependent sensor which can be used to detect the illuminance of the ambient light. Based on the low temperature polysilicon (LTPS) thin film transistor (TFT) process and photosensitivity of a‐Si, the sensor can realize 0‐10K lux of the monitor range and 0.5 lux/step. It saves more space for terminal devices which will also facilitates the full screen display.
