Abstract

The present invention relates to a pixel structure, a display panel, and a display device. The pixel structure includes a substrate, a flat layer formed on the substrate, the flat layer has a groove corresponding to a pixel electrode, and the pixel electrode is located on the In the groove: a pixel defining layer is formed on the flat layer, the pixel defining layer has pixel pits, and the pixel electrodes of the same color are located in the same pixel pit. By using hydrophilic materials to make the flat layer of the drive circuit, and embedding the pixel electrodes in the hydrophilic flat layer, the embedded pixel electrodes can effectively prevent short circuits and tip discharges caused by protrusions on the edges of the pixel electrodes, and then made of hydrophobic materials The pixel defining layer forms an ink deposition area, thereby saving the preparation of the first hydrophilic pixel defining layer, simplifying the manufacturing process of manufacturing the pixel structure, and further saving the manufacturing cost.

Description

technical field [0001] The present invention relates to the technical field of light-emitting devices, and in particular, to a pixel structure, a display panel and a display device. Background technique [0002] The use of solution processing to fabricate OLED and QLED displays is an important direction for future display technology development due to its advantages of low cost, high productivity, and easy realization of large sizes. Among them, printing technology is considered to be the most effective way to realize low-cost and large-area full-color display of OLED and QLED. [0003] In the printing process, due to the influence of equipment precision and droplet size, it is difficult to realize the preparation of high-resolution display panels for the traditional RGB Stripe-arranged pixel structure, and high resolution is the mainstream direction for the development of high-quality display panels in the future. Therefore, in the current printing process, high resolution...
