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.

A display device and a backlight control method of the display device are provided. When a duration of an image occlusion period is shorter than a preset duration, a backlight driving circuit is controlled to respectively provide a first pulse current and a second pulse current in a first light emitting period and a second light emitting period in each frame period, so as to drive a backlight unit to provide a first backlight and a second backlight. Here, the first pulse current is greater than the second pulse current.

A display device includes a casing, a display unit, an optical sensing unit, a driving unit and a processing unit. The processing unit controls the display unit to display a predetermined pattern corresponding to a predetermined range. The predetermined pattern includes a target area. The target area is adjacent to a target position and corresponds to a driving parameter of the driving unit. When the optical sensing unit is located within the target area, the driving unit drives the optical sensing unit to move to the target position by a predetermined manner. When the optical sensing unit is located beyond the target area, the driving unit drives the optical sensing unit to move towards the target position. When the optical sensing unit moves to a boundary of the target area, the driving unit drives the optical sensing unit to move to the target position by the driving parameter.
