Abstract: A mask plate and a method for manufacturing the same are provided. The mask plate comprises a first sub-mask plate and a second sub-mask plate stacked with each other, the first sub-mask plate is provided with at least one first opening therein, a size and a shape of the first opening correspond to those of a target display panel; the second sub-mask plate is provided with a second opening region, which covers at least one of the at least one first opening and includes a plurality of second openings. Since it is only required to ensure that the sizes and shapes of the first openings are the same as those of the target display panels respectively, and it is unnecessary to further manufacture openings for forming pixel patterns, comparing with the existing mask plate, the manufacturing process of the present disclosure is more simple and the manufacturing cost is lower.

Abstract: Disclosed are a pixel arrangement structure, a metal mask, and a display device, and in the pixel arrangement structure, each repeating element includes four sub-pixels distributed in two rows by two columns, where the four sub-pixels include two first sub-pixels in different rows and different columns, and one second sub-pixel and one third sub-pixel in different rows and different columns. While an image is being displayed, any one first sub-pixel together with one second sub-pixel adjacent thereto and one third sub-pixel adjacent thereto can constitute a light-emitting pixel, so that the image can be displayed at a high resolution using a physical low resolution through borrowing between the sub-pixels.

Abstract: The embodiments of the present invention provide an organic electroluminescent display device, a driving method thereof and a display device. Due to the regular staggered arrangement of sub pixels with the same color on the basal substrate, during the manufacture of a metal mask plate, the distance between adjacent openings corresponding to the sub pixels with the same color in the metal mask plate can be relatively large, improving the strength of the metal mask plate; this is beneficial for manufacturing small-sized sub pixels, thereby further improving the resolution of the organic electroluminescent display device.
