Display panel and display device

Abstract

The invention discloses a display panel and a display device, and relates to the technical field of display. The display panel comprises an array substrate, a light-emitting diode structure and an optical adjustment layer, wherein the light-emitting diode structure is arranged on the array substrate and comprises light-emitting units which are arranged in an array way, each light-emitting unit comprises a first color light-emitting unit, a second color light-emitting unit and a third color light-emitting unit, the optical adjustment layer is arranged at one side, far away from the array substrate, of the light-emitting unit, the optical adjustment layer comprises an organic dye, and the organic dye is used for absorbing a part of light emitted from the first color light-emitting unit and / or absorbing a part of light emitted from the second color light-emitting unit. Therefore, the proportion of light emitted by the first color light-emitting unit, the second light-emitting unit and thethird light-emitting unit from the display panel and the display device is same or basically same as expected light proportion, the color cast of the prior art is improved, and the display effect ofthe display panel and the display device are favorably improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular, to a display panel and a display device. Background technique [0002] In recent years, Organic Light-Emitting Diode (OLED) has become a very popular flat-panel display industry at home and abroad, and has been hailed as the next-generation "star" flat-panel display technology, mainly because OLED has self-luminescence, Wide viewing angle, fast response time, high luminous efficiency, thin panel thickness, large-size and bendable panels can be produced, simple manufacturing process, and low cost. [0003] As flexible display products attract more and more attention, the requirements for packaging of flexible display products are also getting higher and higher. Thin-film packaging is one of the most commonly used packaging methods for flexible display products. The thin-film packaging layer is usually formed by alternately stacking inorganic layers and organic layers. T...

Problems solved by technology

The combination of the refractive index of the inorganic layer and the organic layer in the thin film encapsulation layer has different effects on the RGB light output rate of the OLED device. The refractive index of the inorganic layer is generally 1.7-1.9 in the visible light range. The refractive index of the inorganic layer can be obtained by PECVD (Plasma Enhanced Chemical Vapor Deposition ), that is, adjusted by the plasma enhanced chemical vapor deposition method, and the visible light range refractive index of the organic layer is generally around 1.5. The intensity of light waves of different wavelengths varies greatly, resulting in changes in the light ratio, and deviations from the expected light ratio, resulting in a large color shift in the display of OLED products, and the display effect is not good
