Display with a luminance and color temperature control system and method for controlling the luminance of a display

摘要

A display (20) includes a display module (21), a light source (22), a light source driving circuit (24), a display driving circuit (26), and an optical sensor (28). The optical sensor is installed next to the light source for detecting the luminance and color temperature of the light source. The optical sensor is coupled to the display driving circuit for generating a feedback signal (FB) to the display driving circuit according to the luminance and the color temperature of the light source. The display driving circuit drives the display module to display an image according to a received image signal (29) and updates the data of the image signal according to the feedback signal so as to adjust the luminance and the color temperature of the image.
