    Abstract: A display device includes a storage unit, a display unit and a processing unit. The storage unit stores a color parameter under a color space. The display unit displays an adjusting interface including a reference color block and a plurality of offset color blocks. When a target offset color block of the offset color blocks is selected, the processing unit updates a color coordinate of the reference color block by a color coordinate of the target offset color block and updates a color coordinate of each of the offset color blocks by a color coordinate of the updated reference color block and an offset value. The processing unit obtains a color transformation matrix according to the color coordinate of the reference color block, the color coordinate of the target offset color block and the color parameter. The processing unit adjusts three output percentages of RGB by the color transformation matrix.

    Abstract: 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.

    Abstract: 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.
