Abstract
An adjustment method of screen brightness comprises the following steps. Step (a): obtaining a relationship between a brightness and refresh rate of the screen. Step (b): adjusting the screen to a highest refresh rate and displaying an image at a first brightness. Step (c): decreasing the first brightness by a unit brightness value and variably displaying the image between a first refresh rate and a second refresh rate. Step (d): determining whether the image does not flicker; if not, repeating step (c). Step (e): calculating a first brightness difference between a decreased brightness of the screen and a brightness corresponding to a lowest refresh rate when the image does not flicker. Step (f): determining whether the first brightness difference is less than a screen flicker threshold; if yes, decreasing the first brightness corresponding to the highest refresh rate to obtain an adjusted brightness corresponding to the highest refresh rate.
