Problems solved by technology

During the drying process of the ink, since the solvent evaporation rate at the edge of the pixel pit is faster than that at the center, the solvent loss at the edge is more in the same time, resulting in a gradient of solute concentration between the edge and the center. The solvent in the center wants to flow to the edge, and at the same time, it drives a part of the solute to flow to the edge, which leads to the accumulation of solute at the edge. After the ink is dried and formed into a film, the edge is thicker, while the center is thinner, and the film formation is uneven.
For optoelectronic display devices, the poor morphology and uniformity of the dry film have a great impact on the life of the device and the display effect

Abstract

The invention discloses a display panel, a display device and a manufacturing method of the display panel, which relate to the display field and achieve the purpose of making the film formation of the pixel film of the display panel more uniform. The main technical solution of the present invention is: comprising: a pixel defining layer, on which a plurality of pixel pits are arranged, and on one side of part or all of the pixel pits, the pixel defining layer is respectively provided with auxiliary grooves. The invention is mainly used in the manufacture of pixel films of display panels.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel, a display device and a manufacturing method of the display panel. Background technique [0002] Organic Light Emitting Diode (OLED) is known as a new generation of display technology. Due to its advantages of high response, high contrast, and flexibility, it is considered to have a wide range of application prospects. The inkjet printing technology in the OLED film formation technology is considered to be an important way to realize the mass production of large-size OLEDs due to its high material utilization rate. [0003] In the inkjet printing process, it is an essential step to remove the solvent through the subsequent process, so that the solute is dried to form the required film. During the drying process of the ink, since the solvent evaporation rate at the edge of the pixel pit is faster than that at the center, the solvent loss at the edge is more in the same...
