Liquid crystal display panel alleviating color shift problem due to large viewing angle

A display device, comprising:

• a display panel, comprising a plurality of pixel groups, each of the pixel groups comprising two blue sub-pixels;
• the display device further comprises a processor and a memory storing computer readable instructions thereon, which, when executed by the processor, cause the processor to:
• obtain a pre-display image, wherein each sub-pixel in the pre-display image corresponds to a preset grayscale value;
• obtain, according to an average of preset grayscale values corresponding to the two blue sub-pixels in the pixel groups, n sets of target grayscale value pairs corresponding to the pixel groups by table lookup;
• wherein each set of the target grayscale value pairs comprises a first target grayscale value and a second target grayscale value, the first control module is configured to control the grayscale value differences of the n sets of target grayscale value pairs to be different, and the grayscale value difference is equal to the first target grayscale value minus the second target grayscale value of a same set of target grayscale value pairs;
• drive the display panel to display a same pre-display image in m continuous frames of a display cycle;
• and
• wherein in a same frame of the display cycle, grayscale values of two blue sub-pixels in the pixel group are the first target grayscale value and the second target grayscale value in a set of target grayscale value pairs;
• the second control module is configured to control the first target grayscale value of each set of target grayscale value pairs to be greater than a preset grayscale value of a corresponding blue sub-pixel and the second target grayscale value to be smaller than a preset grayscale value of a corresponding blue sub-pixel, and in at least two frames of the display cycle, and target grayscale value pairs corresponding to pixel groups in a same position on the display panel are different, wherein m is an integer greater than 1, and n is an integer greater than 1 and less than or equal to m.
