Abstract:
1. A backlight adjusting system adapted for adjusting a backlight brightness of a light emitting element for a display panel based on ambient light around the display panel, said backlight adjusting system comprising: a first calculator configured to calculate a target display brightness value of the display panel based on an actual ambient brightness value of the ambient light, a predetermined optimal ambient brightness value of the ambient light, and a predetermined optimal display brightness value of the display panel determined according to the predetermined optimal ambient brightness value; a processor electrically coupled to said first calculator and configured to obtain a target pulse duty value based on the target display brightness value; and a driver electrically coupled to said processor and configured to generate a driving signal based on the target pulse duty value utilizing pulse width modulation techniques for driving the light emitting element so as to adjust the backlight brightness of the light emitting element, wherein the target display brightness value=the actual ambient brightness value×the predetermined optimal display brightness value/the predetermined optimal ambient brightness value.
