Problems solved by technology

However, the polarizer will cause a loss of transmittance (about 50%). The current development direction is to use the COE (BM+color filter) method above the OLED to replace the polarizer for anti-glare. However, due to the increased BM ( Black matrix) is equivalent to a layer of grating, ambient light (polychromatic light) will be strongly diffracted after reflection, and colored glare will appear, especially when the screen is off

Abstract

The invention relates to an OLED display substrate which comprises an OLED light-emitting device and a functional film layer arranged on the light-emitting side of the OLED light-emitting device and is used for converting external environment light from coherent light to incoherent light and improving glare. The invention further relates to a display device.

Description

technical field [0001] The invention relates to the technical field of display product manufacturing, in particular to an OLED display substrate and a display device. Background technique [0002] In conventional OLEDs, a polarizer (POL) with a quarter-wave plate is usually used to prevent or reduce the reflection of ambient light (such as the sun) in order to increase the contrast. However, the polarizer will cause a loss of transmittance (about 50%). The current development direction is to use the COE (BM+color filter) method above the OLED to replace the polarizer for anti-glare. However, due to the increased BM ( Black matrix) is equivalent to a layer of grating, and the ambient light (polychromatic light) will be strongly diffracted after reflection, resulting in colored glare, especially when the screen is off. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides an OLED display substrate and a display dev...
