Problems solved by technology

When some sub-pixels are lit, the current will be transmitted laterally to adjacent sub-pixels, causing other sub-pixels to emit light, which will cause mutual interference between adjacent sub-pixels and affect the display effect

Abstract

The invention discloses a display panel, a preparation method of the display panel and a display device. The display panel includes a substrate, a pixel defining layer and at least one first carrier sublayer, wherein the pixel defining layer is located on one side of the substrate, the pixel defining layer comprises a pixel opening penetrating through the thickness of the pixel defining layer, thepixel opening comprises a first sub-opening and a second sub-opening which communicate with each other in the thickness direction of the pixel defining layer, the first sub-opening is located on theside close to the substrate, and the second sub-opening is located on the side, away from the substrate, of the first sub-opening; and the at least one first carrier sublayer comprises a first part and a second part which are separated from each other, the first part is located in the first sub-opening, and the second part is located on the inner surface of the second sub-opening. According to thedisplay panel provided by the invention, current crosstalk between adjacent sub-pixels can be avoided.

Description

technical field [0001] The present invention 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 Diode (OLED) display has the advantages of low cost, wide viewing angle, low driving voltage, fast response speed, rich luminous color, simple preparation process, and large-area flexible display. It is considered to have the most development prospects. One of the display technologies. [0003] During the preparation of OLED display panels, functional layers such as hole injection layer, hole transport layer, hole blocking layer, and electron blocking layer on both sides of the light-emitting layer are usually evaporated using a common mask. Each sub-pixel is connected along a direction parallel to the display panel. When some sub-pixels are turned on, the current will be transmitted laterally to adjacent sub-pixels, causing other sub-pi...
