And a display device substrate

The invention relates to the field of organic light emitting display and provides a substrate and a display device. The substrate is an array substrate or a color film substrate and comprises a plurality of pixel sets which are arranged in an array and partition mode, and each pixel set is composed of a 3*3 sub-pixel array. Each pixel set comprises at least two red sub-pixels, at least two green sub-pixels, at least two blue sub-pixels and one white sub-pixel, wherein the white sub-pixel is located in the center of the 3*3 sub-pixel array. The sub-pixels in each pixel set form two pixel units sharing the corresponding white sub-pixel. Each pixel unit comprises at least one red sub-pixel, at least one green sub-pixel, at least one blue sub-pixel and the white sub-pixel. As every two adjacent pixel units share one white sub-pixel, the data volume and output number of data chips are reduced, and the structure of the array substrate or the color film substrate is simplified.
