A control method of a display includes a statistics circuit, a backlight determining circuit and a backlight control circuit. The display includes a backlight module having a maximum power. The statistics module receives frame, and generates luminance statistical information of a plurality of blocks included in the frame. The backlight determining circuit determines a backlight intensity corresponding to each of the blocks according to the luminance statistical information of the blocks and the maximum power. At least one of the backlight intensities corresponding to the blocks is greater than a normal luminance, which is a backlight intensity corresponding to one of the blocks when the maximum power is evenly distributed on light emitting elements of the display. The backlight control circuit controls the luminance of the backlight module according to the backlight intensities.

A display device includes: a first subpixel including a quantum dot light-emitting layer configured to emit light of a first color: a second subpixel including a quantum dot light-emitting layer configured to emit light of a second color different from the light of the first color: a third subpixel including a quantum dot light-emitting layer configured to emit light of a third color different from the light of the first color and the light of the second color: and a data processing circuit configured to receive a first input data corresponding to the first subpixel, a second input data corresponding to the second subpixel, and a third input data corresponding to the third subpixel. The data processing circuit generates first output data corresponding to a first data voltage supplied to the first subpixel by using the first input data, the second input data, and the third input data.

The present disclosure relates to a method and a device for compensating for a luminance deviation. A difference in pixel value of the image capturing device between a first pixel and a second pixel in the screen and a difference in gray scale level between first and second gray scale levels are derived from a captured image at the first gray scale level and a captured image at the second gray scale level which include pixel values of the image capturing device. A pixel value for the second pixel is calculated from the captured image at the first gray scale level.

A method includes modeling, by a computing device, color saturation variations of different hues in a working color space with one or more properties of responses of a human vision system (HVS) to color stimulus. The computing device further generates one or more color saturation variation models based on the responses of the HVS to color stimulus.

Image data for a current image frame may be compensated for transient response variations due to variations in display panel temperatures at various positions of the display panel by performing pixel drive compensation. The pixel drive compensation may be performed based at least in part upon display panel temperatures at various portions of the display panel. In this way, drive compensation corresponding to various temperature variations in a display panel may be implemented.
