Abstract

An adaptive display backlight control system and a method for controlling the backlight are provided. The system includes a microcontroller unit, a human presence sensor, a human attention sensor and a backlight regulation module. The microcontroller unit determines a driving signal applied to a backlight module of a display according to a signal relating to if a person is present in front of the display as provided by the human-presence sensor, and a signal relating to if the person pays attention to the display as provided by the human attention sensor. Further, the microcontroller unit can obtain information of ambient light around the display from an ambient light sensor, and then relies on the information of ambient light to regulate the driving signal applied to the backlight module.
