Display device, organic light emitting display panel and manufacturing method thereof

Abstract

The application discloses a display device, an organic light emitting display panel and a manufacturing method thereof. Wherein, the organic light-emitting display panel includes: a first substrate; at least two pixel definition layers located on one side surface of the first substrate, and the pixel definition layers are insulated from each other; multiple pixels located on the surfaces of the at least two pixel definition layers a display pixel, the display pixel includes a first sub-pixel, a second sub-pixel and a third sub-pixel, wherein at least two of the first sub-pixel, the second sub-pixel and the third sub-pixel are located in different Pixels define the layer surface. The organic light-emitting display panel reduces the possibility of signal crosstalk caused by signal coupling when adjacent sub-pixels receive display signals during the display process; and improves the display due to the increase in the distance between adjacent sub-pixels The pixel design space increases the designable width of the wiring between the display pixel and the pixel driving film layer of the organic light emitting display panel.

Description

technical field [0001] The present application relates to the field of display technology, and more specifically, to a display device, an organic light-emitting display panel and a manufacturing method thereof. Background technique [0002] With the continuous development of display technology, the application of display panels is becoming more and more extensive. Organic Light Emitting Diode (OLED) display panels have become a rising star in the display panel industry due to their advantages such as fast response speed, brilliant colors, thinness and convenience. [0003] refer to figure 1 , figure 1 It is a schematic cross-sectional structure diagram of an organic light-emitting display panel in the prior art, specifically including: a substrate 10, a pixel driving circuit 20 located on the surface of the substrate 10, and a pixel definition layer 40, the pixel definition layer 40 has a plurality of connection through holes 30, A plurality of display pixels located on th...

AI Technical Summary

Problems solved by technology

[0004] As the pixel density (Pixels Per Inch, PPI) of organic light-emitting display panels continues to increase, the number of display pixels required to be carried by the substrate 10 is also increasing, resulting in a gap between each display pixel and each display pixel. The distance between the included sub-pixels is getting smaller and smaller, so that the problem of signal crosstalk between adjacent sub-pixels is very easy to occur, which has a negative impact on the display effect of the organic light-emitting display panel.
