Problems solved by technology

[0003] There are some common layers in the OLED display panel. Due to the good conductivity of the common layer, when controlling the light emission of a certain light-emitting pixel, a lateral leakage current will be generated, which will cause other light-emitting pixels to steal light.

Abstract

The invention discloses a display panel, a preparation method thereof and a display device. The display panel comprises a substrate; a pixel definition layer located on one side of the substrate, wherein the pixel definition layer comprises a plurality of pixel openings distributed in an array mode and a body part surrounding the pixel openings; a carrier layer positioned on one side, back to thesubstrate, of the pixel definition layer; wherein the carrier layer is in contact with the metal, a recess for inhibiting the transverse conduction capability of the carrier layer is formed in the carrier layer, and the orthographic projection of the trap on the substrate is overlapped with the orthographic projection of the body part on the substrate. According to the embodiment of the invention,transverse leakage flow can be reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a method for preparing the display panel, and a display device. Background technique [0002] Organic Light Emitting Display (OLED) display panels are widely used in mobile phones, TVs, and personal digital assistants due to their advantages such as high image quality, power saving, thin body, and wide application range. , digital cameras, notebook computers, desktop computers and other consumer electronics products have become the mainstream of display panels. [0003] There are some common layers in the OLED display panel. Because the common layer has good conductivity, when controlling a certain light-emitting pixel to emit light, a lateral leakage current will be generated, thereby causing other light-emitting pixels to steal light. [0004] Therefore, how to reduce the lateral leakage has become an urgent technical problem to be solved by those s...
