Problems solved by technology

[0003] The pixel arrangement in the current OLED display device is generally a Pentile arrangement or an RGB arrangement, and when a mask is used to prepare a display device, the evaporated mask is used to define the pixel array located in the display area. A sub-pixel corresponds to a mask opening, and with the reduction of the size of the sub-pixel, the size of the mask opening becomes smaller and smaller, resulting in an increasingly accurate alignment when forming a pixel array by evaporation. High, the corresponding difficulty of the process is also increasing, which greatly reduces the yield of the product and increases the cost of the process

Abstract

The invention provides a pixel array and a manufacturing method of a display device comprising the pixel array. Based on a traditional pixel array arrangement mode, sub-pixels with the same luminescence color are integrated into one sub-pixel unit. Based on the condition that pixel array luminescence is not influenced, a mask layer plate opening is used to form one sub-pixel unit in a manufacturing technology. Mask layer plate manufacturing difficulty is effectively reduced and simultaneously a precision requirement in a pixel array manufacturing technology can be greatly decreased. And the formed display device can satisfy a resolution requirement. Through one mask layer plate opening, a plurality of adjacent sub-pixels are formed. Technology difficulty can be effectively reduced, a yield rate of the device is increased and technology cost is reduced.

Description

technical field [0001] The invention relates to the field of manufacturing semiconductor devices, in particular to a pixel array and a method for manufacturing a display device including the pixel array. Background technique [0002] With the advancement of science and technology and the development of society, people have higher and higher requirements for the definition of display devices, which in turn makes the resolution of digital display devices higher and higher, and the size of sub-pixels in corresponding display devices is also getting higher and higher. come smaller. [0003] The pixel arrangement in the current OLED display device is generally a Pentile arrangement or an RGB arrangement, and when a mask is used to prepare a display device, the evaporated mask is used to define the pixel array located in the display area. A sub-pixel corresponds to a mask opening, and with the reduction of the size of the sub-pixel, the size of the mask opening becomes smaller an...
