Pixel Array, Driving Method Thereof, Display Panel and Display Device

A driving method of a pixel array, wherein, the pixel array comprises a plurality of pixel units, each of which comprises three sub-pixels in different colors, in each pixel unit, any two adjacent sub-pixels are combined into a pixel block having a square shape, a width of each of the sub-pixels is a half of a length of each of the sub-pixels, and the driving method comprises steps of:

• S1, calculating theoretical brightness values of an image to be displayed at respective sub-pixels;
• S2, calculating actual brightness values of the respective sub-pixels, wherein, the actual brightness value of each sub-pixel at least comprises a sum of a part of the theoretical brightness value of the sub-pixel and a part of the theoretical brightness values of one or more sub-pixels in the same color as the sub-pixel in the same row;
• and
• S3, inputting signals to the respective sub-pixels, so that the respective sub-pixels reach the actual brightness values calculated in step S2,
• wherein, in step S2, the actual brightness value of each sub-pixel comprises the sum of a part of the theoretical brightness value of the sub-pixel and a part of the theoretical brightness values of two or more sub-pixels in the same color as the sub-pixel in the same row minus a part of the theoretical brightness values of six or more sub-pixels in the same color as the sub-pixel in different rows.
