Display panel, manufacturing method thereof, and display device

Abstract

The invention discloses a display panel, a manufacturing method thereof and a display device. The display panel has a plurality of pixel areas, each pixel area is composed of multiple sub-pixels of the same color, the array substrate includes a base layer and an array layer; the display layer is arranged on the side of the array layer away from the base layer; the display layer includes an anode metal layer, There are multiple anodes, one sub-pixel includes one anode; the first pixel defining layer is arranged on the side of the anode metal layer away from the array layer, the first pixel defining layer has a plurality of first openings exposing the anode, and one pixel region includes one The first opening; the second pixel defining layer, made of hydrophobic material, including a first defining portion disposed on the first pixel defining layer and a second defining portion located in the first opening, the second defining portion divides the first opening A plurality of second openings are formed, one sub-pixel includes one second opening; the organic light emitting layer is disposed in each second opening. Fixed display panel color crosstalk issue.

Description

technical field [0001] The present invention relates to the technical field of semiconductors, and more particularly, to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) is also called organic electro-laser display, organic light-emitting semiconductor. OLED display technology has the advantages of self-illumination, wide viewing angle, almost infinitely high contrast ratio, low power consumption, and extremely high response speed. It is widely used in mobile phones, digital cameras, notebook computers, car audio, and televisions. [0003] In OLED display panel technology, since the light-emitting layer is produced by printing process, it is difficult to realize the preparation of high-resolution display panel by adopting the traditional RGB arrangement of pixel structure due to the influence of equipment precision and droplet size of the material of the ligh...

Problems solved by technology

[0003] In the technology of OLED display panel, since the light-emitting layer is made by printing process, it is difficult to realize the preparation of high-resolution display panel by adopting the traditional RGB pixel structure, which is affected by the precision of the equipment and the droplet size of the material of the light-emitting layer.

In the prior art, the sub-pixels of the same color in adjacent pixels share the openings on the mask, and the resolution is improved through different pixel designs. figure 1 It is a schematic top view of a display panel in the prior art, such as figure 1 As shown, in this technology, since the light-emitting devices of some sub-pixels sp' of two adjacent pixels 1P' and 2P' are connected together, when two pixels 1P' and 2P' are given different voltages, adjacent The mutual influence between the sub-pixels 1sp' and 2sp' of the same color in the pixel produces color crosstalk and affects the display effect of the display panel
