Abstract

The invention relates to a pixel structure, a display panel and a display device. The pixel structure comprises a substrate, a planarization layer and a pixel defining layer, the planarization layer is formed on the substrate, grooves are formed in the planarization layer and are corresponding to pixel electrodes, the pixel electrodes are arranged in the grooves, the pixel defining layer is formedon the planarization layer, pixel pits are arranged in the pixel defining layer, and the pixel electrodes with same color are arranged in the same pixel pit. The planarization layer for driving a circuit is made of hydrophilic material, the pixel electrodes are embedded into the hydrophilic planarization layer, edges of the pixel electrodes can be effectively prevented from protruding to cause short-circuit and tip discharging phenomena by the embedded pixel electrodes, the pixel defining layer is made of a hydrophobic material to form an ink deposition region, so that the fabrication of a first hydrophilic pixel defining layer is omitted, the fabrication process of the pixel structure is simplified, and the fabrication cost is further reduced.

Description

technical field [0001] The present invention relates to the technical field of light emitting devices, in particular to a pixel structure, a display panel and a display device. Background technique [0002] The use of solution processing to manufacture OLED and QLED displays is an important direction for the future development of display technology 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 OLED and QLED low-cost and large-area full-color display. [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 RGBStripe pixel structure, and high-resolution is the mainstream direction of high-quality display panel development in the future. Therefore, in the current printing process, other pixel structure designs are...
