Display device, display panel, pixel structure and mask

technical field

The present disclosure relates to the field of display technology, in particular, to a display device, a display panel, a pixel structure and a mask.

Background technique

OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display devices have been more and more widely used due to their advantages of high brightness and good image quality. The evaporation process is a common process for forming the organic light-emitting layer in the OLED panel. During the evaporation process, a mask needs to be used for shielding. There are openings on the mask, and the luminescent material can be evaporated according to the opening shape of the mask. To a designated position of a substrate, a plurality of pixels distributed in an array are formed, each pixel includes sub-pixels of at least three colors, and sub-pixels of different colors can pass through different masks.

However, as the resolution of the product increases, the number of pixels per unit area increases, and the size of the pixels decreases, resulting in a corresponding decrease in the opening of the mask, which increases the difficulty of the manufacturing process, and the smaller openings will make the It is more difficult to align the substrate and the mask plate, and it is difficult to ensure the position of the pixels, which will lead to a decrease in the yield of the product. At the same time, although two sub-pixels of the same color can be arranged adjacent to each other so as to share one opening and increase the size of the opening, this will make the pixels not evenly arranged and reduce the display effect.
