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.

Adjustment method of screen brightness

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.

Display device and backlight control method thereof

A display device includes a display computing module coupled to a signal source and configured to receive an audio/video signal from the signal source; an audio computing module coupled to the display computing module, the audio computing module configured to receive the audio/video signal from the display computing module and to obtain a sound information including orientation data, the audio computing module outputting the sound information to enable the display computing module to generate a control signal based on the sound information; and a light source device coupled to the display computing module, the light source device including multiple light-emitting areas corresponding to the orientation data, the light source device configured to control a light-emitting status of at least one light-emitting area according to the control signal.
