Abstract: The present disclosure discloses an array substrate, a liquid crystal display panel, and a display apparatus, which relate to the field of display technologies. The array substrate includes a first base and a plurality of photosensitive devices disposed on the first base. The photosensitive device can recognize fingerprints. In this way, the screen-to-body ratio of a display apparatus manufactured by using the array substrate is effectively increased. When an orthographic projection of the photosensitive device in the array substrate onto the first base at least partially overlaps with a white sub-pixel region, a pixel aperture ratio of the array substrate can be increased, so that a display apparatus that is subsequently manufactured by using the array substrate has a relatively good display effect.

Abstract: The disclosure relates to a display panel, a display method thereof and a display device. The method comprises: confirming a received image to be displayed as a preset pure-coloured image; for each of the green subpixels, comparing the grayscale value that the green subpixel corresponds to with that of the red subpixel or the blue subpixel at a place corresponding to the green subpixel in a previous row to find out the difference; and adjusting the grayscale value of the green subpixel for displaying based on the difference. The grayscale value of the green subpixel is increased or decreased by a preset value according to whether the difference is greater than 0. Thereby the charging capacities of all the green subpixels are substantially the same, so as to avoid brightness difference and eliminate light and dark stripes appearing in the display panels.
