Organic light-emitting diode display panel and display device

Abstract

The invention provides an organic light-emitting diode display panel and a display device. The display panel comprises a display substrate and a phase function layer arranged on the display substrate,wherein the display substrate comprises a plurality of pixel units; the phase function layer comprises a plurality of phase hysteresis layers; each phase hysteresis layer corresponds to one pixel unit; and the phase hysteresis layer is used for converting the linearly polarized light passing through the phase hysteresis layer into circularly polarized light. The display panel and the display device provided by the invention are high in anti-reflection capability, not interfered by external light when a picture is displayed, high in definition, and favorable for realizing the light and thin design of the display panel and the display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic light emitting diode display panel and a display device. Background technique [0002] With the development of science and technology and the improvement of people's requirements for products, more and more flexible display screens are valued and favored by the market. Compared with liquid crystal display panels, organic light emitting diode display panels have inherent advantages in the structure of flexible display screens. Therefore, major panel manufacturers have invested more energy in the research and development of flexible organic light emitting diode display screens. [0003] The thickness of the display screen will have a greater impact on the flexible characteristics of the display screen, and the thinner the display screen is, the more favorable it is to realize its flexible characteristics. At present, in order to eliminate the reflection effect of the d...

AI Technical Summary

Problems solved by technology

The polarizer is a composite film composed of multiple layers of organic materials, which includes at least one phase retardation layer, one linear polarizing layer and a multi-layer protective film, so it has a relatively large thickness, which is not conducive to the realization of light and thin display screens

In addition, the phase retardation layer in the currently used polarizer is an integral structure. The retardation coefficient of the phase retardation layer of this overall structure cannot meet the phase requirements of the entire visible light band at the same time, so some light cannot pass through the phase retardation layer and be linearly polarized. Transformed into circular polarized light, and this part of the light cannot be extinguished by the linear polarizing layer after being reflected by the cathode, resulting in light leakage, which seriously reduces the anti-reflection ability of the display screen
