An array substrate includes a plurality of first pixel-unit columns and a plurality of second pixel-unit columns repeatedly alternating with each other along a first direction. The first pixel-unit column includes a plurality of first pixel-unit groups and a plurality of second pixel-unit groups repeatedly alternating with each other along a second direction. The second pixel-unit column includes a plurality of third pixel-unit groups and a plurality of fourth pixel-unit groups repeatedly alternating with each other along the second direction. Each of the first pixel-unit group, the second pixel-unit group, the third pixel-unit group, and the fourth pixel-unit group includes a plurality of sub-pixels arranged into a matrix. The first pixel-unit group and the second pixel-unit group have same quantities of rows and columns in one matrix. The third pixel-unit group and the fourth pixel-unit group have same quantities of rows and columns in one matrix.

A display panel includes a driver, X data lines, Y scan lines, and X*Y pixels. The driver is configured to receive display data with X*Y resolution. The X data lines are electrically connected to the driver and configured to receive a plurality of pixel voltages. The X*Y pixels are electrically connected to the data lines and the scan lines. When each gray level of a first color display data set is identical and lower than a first threshold value, the pixel voltages of the plurality of first color subpixels are not identical.

An array substrate, including: a base substrate, and a plurality of first signal lines, a plurality of second signal lines, a plurality of touch-control signal lines, a first transparent conductive layer and a second transparent conductive layer, which are arranged on the base substrate. The first transparent conductive layer and the second transparent conductive layer are located on the side of the touch-control signal lines that is away from the base substrate.
