  • Patent number: 10345666
    Abstract: An array substrate includes a plurality of display pixels arranged in an array. Each of the plurality of display pixels comprises a red subpixel R, a green subpixel G, and a blue subpixel B. Six of the consecutive display pixels arranged horizontally and/or longitudinally as a whole are repeatedly arranged in a pixel unit. An arrangement order of the subpixels in each of the six consecutive display pixels is totally different. The subpixels in the six consecutive display pixels are arranged as RGB, RBG, GRB, GBR, BRG, and BGR successively. The technical problems of the conventional tri-gate driver structure, such as poor image display and display quality, are resolved due to poor charging ability of pixels which are inclined to incomplete charging.
