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 color correction system and a colorimeter positioning method therefore are provided. A first color block is displayed in a first display area of a display. During the period of displaying the first color block, a first sensing value is acquired for the first color block through a sensor of a colorimeter. The first sensing value is compared with a first reference value to determine whether the first sensing value meets the first specific condition. In response to the first sensing value meeting the first specific condition, a second color block is displayed in the first display area of the display. During the period of displaying the second color block, a second sensing value is acquired for the second color block through the sensor. The second sensing value is compared with a second reference value to determine whether the second sensing value meets the second specific condition.

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 storage unit, a display unit and a processing unit. The storage unit stores an original coordinate of a reference point and a color parameter under a color space, wherein the color space has been processed by color calibration in advance. The display unit displays an adjusting interface. The adjusting interface is configured to shift the reference point to generate a shift coordinate of the reference point. The processing unit is coupled to the storage unit and the display unit. The processing unit obtains a color transformation matrix according to the original coordinate of the reference point, the shift coordinate of the reference point and the color parameter. The processing unit adjusts three output percentages of RGB by the color transformation matrix.
