Description:

Aiming at the problem of poor accuracy when integrating light Sensor into LCD to detect ambient light illumination, this paper proposes a method to improve the stability and accuracy of a-Si LCD with ambient light sensor, mainly by designing TFT Sensor with different sizes, optimizing light sensor driving circuit, optimizing light sensor algorithm and differentiating driving IC to improve the accuracy of existing light sensor testing.
