1results about How to "Increase backlight brightness" patented technology

The application discloses an ambient light self-adaptive liquid crystal display module, which comprises a shell and a panel, and further comprises a sliding rheostat arranged in the shell and used for controlling backlight brightness, a photosensitive resistor arranged on the panel and used for receiving external ambient light, and a comparison controller arranged in the shell and used for controlling the sliding rheostat, which is electrically connected with the sliding rheostat through a first sensor and electrically connected with the photosensitive resistor through a second sensor. The photosensitive resistor, the comparison controller and the two sensors are arranged, the effective resistances of the sliding rheostat and the photosensitive resistor are collected by the sensors in real time, and are converted into electric signals and sent into the comparison controller for comparison. When the difference between the two electric signals is positive, the resistance of the sliding rheostat is controlled to increase the backlight brightness; when the difference between the two electric signals is negative, the resistance of the sliding rheostat is controlled to reduce the backlight brightness, so that the self-adaptive adjustment of the backlight brightness to the ambient light is realized.
