Organic light emitting display panel and display

Abstract

The invention provides an organic light emitting display panel and a display. The organic light emitting display panel comprises a first substrate, and a reflection layer positioned between the firstsubstrate and a light emitting device layer of the organic light emitting display panel, wherein the reflection layer comprises an organic grating layer and a reflective film covering the surface of the organic grating layer, a plurality of grooves arranged at intervals are arranged on one surface, facing the organic light emitting layer of the organic light emitting display panel, of the organicgrating layer, and the reflective film covers the grooves. According to the organic light emitting display panel provided by the invention, light that does not propagate along the light exit directionin the organic light emitting display panel is reflected to the light exit side, and thus the luminous efficiency of the organic light emitting display panel is enhanced.

Description

technical field [0001] The present application relates to the field of organic light-emitting display devices, in particular to organic light-emitting display panels and displays. Background technique [0002] Since the birth of organic light-emitting display technology, it has developed rapidly due to its advantages such as wide viewing angle, high contrast ratio, wide color gamut, and fast response speed. Each pixel of such a display device consists of a cathode, an anode and an organic layer located between them. Appropriate voltage is applied to the cathode and anode, the holes are from the anode to the light-emitting layer through the hole injection layer and the hole transport layer, and the electrons are from the cathode to the light-emitting layer through the electron injection layer and the electron transport layer, and the two are recombined in the light-emitting layer. glow. [0003] However, the luminous efficiency of the organic light-emitting display panel in...

Problems solved by technology

[0003] However, the luminous efficiency of the organic light-emitting display panel in the prior art is not high, and it cannot meet the user's display and lighting needs well, and part of the light emitted by the organic light-emitting display panel does not propagate along the light-emitting direction, which reduces the brightness of the display panel. Luminous efficiency, it is necessary to make the light of the organic light-emitting display panel propagate from the light-emitting side as much as possible, so as to improve the luminous efficiency of the organic light-emitting display panel
