OLED luminous layer structure capable of avoiding color cast and coupled film of OLED luminous layer structure

Abstract

The invention discloses an OLED luminous layer structure capable of avoiding color cast and a coupled film of the OLED luminous layer structure. The OLED luminous layer structure capable of avoiding the color cast comprises an OLED luminous layer and a polarizer arranged on the OLED luminous layer, wherein the OLED luminous layer further comprises a red color block, a green color block and a blue color block which are arranged in sequence, the coupled film is arranged on the polarizer, and grid type protrusions are arranged at the portions, corresponding to color areas where the color cast is generated in the red color block, the green color block and the blue color block, of the coupled film. The coupled film is added on the polarizer, an oval grid type protrusion structure arranged on the coupled film is utilized, light getting out quantity in a certain direction is added or reduced oriented to the color areas where the color cast is generated in the red color block, the green color block and the blue color block and which correspond to the oval grid type protrusion structure, in this way, the purpose of regulating hue energy is achieved, R color energy, G color energy and B color energy are gathered and blended proportionally in the certain direction, white light without the color cast is obtained, the color cast of a display screen is eliminated, and the overall optical quality of a mobile phone panel is improved.

Description

technical field [0001] The invention relates to a manufacturing process of an optical element, in particular to an OLED light-emitting layer structure capable of avoiding color shift and a coupling film thereof. Background technique [0002] In terms of color control, OLED does not require a backlight source, so it is enough to only control the color of the color filter (Color filter, referred to as CF) layer, and the current CF production technology for OLED directly uses RGB organic materials, but due to The organic material itself will lose the light intensity, coupled with the change of the supply flow of the device itself, the energy emitted by the R, G, and B three-color lights will be unevenly distributed in certain directions (compared to the proportional mixing), resulting in mobile phone screen There will be serious color shift. [0003] refer to figure 1 As shown, when the light of the three colors of R, G, and B enters the light-emitting layer, we divide the wh...
