Problems solved by technology

This increases the manufacturing process of organic light-emitting display panels and reduces the yield rate of white light organic light-emitting display panels.
[0003] At the same time, the blue light-emitting layer in the prior art will lead to a significant decrease in the brightness of the blue light with the prolongation of the use time. In order to improve the stability of the blue light brightness, the current density of the blue pixel is usually increased. In this way, the organic light will be further reduced. Service life of illuminated display panels

Abstract

The invention discloses an organic light emitting display panel and an organic light emitting display device. The organic light emitting display panel comprises a substrate, and a first electrode, a first transmission layer, an organic light emitting layer, a second transmission layer and a second electrode sequentially arranged on the substrate, wherein the organic light emitting layer comprises a blue light-emitting layer and a sapphire light-emitting layer. The wavelength scope of the blue light emitted by the blue light-emitting layer is 460nm-490nm, and the wavelength scope of the sapphire light emitted by the sapphire light-emitting layer is 425nm-455nm. The organic light emitting display panel further comprises a chroma adjustment layer which is arranged on one side of the second electrode away from the substrate, and the chroma adjustment layer is used for adjusting the light emitted from the second electrode. A blue light-emitting layer and a sapphire light-emitting layer improve the light extracting rate of the organic light emitting display panel and prolong the service lifetime of the organic light emitting layer. The display effect of the organic light emitting display panel is improved.

Description

technical field [0001] The present invention generally relates to the field of display technology, and in particular to an organic light emitting display panel and an organic light emitting display device. Background technique [0002] In the existing organic light emitting display panel technology, in order to obtain white light emitted from the organic light emitting display panel, the organic light emitting layer in the organic light emitting display panel is usually provided with three layers of blue light emitting layer, red light emitting layer and green light emitting layer, and at the same time A charge generation layer is arranged between every two light-emitting layers, and white light is formed by changing the luminous efficiency and brightness ratio of the three-color light-emitting layers. This increases the manufacturing process of the organic light emitting display panel and reduces the yield rate of the white light organic light emitting display panel. [00...
