A kind of oled display substrate and display device

Abstract

The invention provides a substrate for OLED display and a display device, relates to the field of display technology, and solves the problems of complex driving and high power consumption caused by adjusting color coordinates or color temperature balance of the existing OLED display device and driving other sub-pixels. A substrate for OLED display, including a color filter layer, the color filter layer includes at least four different color filter patterns, wherein, the display substrate is formed with a red filter pattern at a position corresponding to the first sub-pixel, and the A green filter pattern is formed at a position corresponding to the second sub-pixel, a blue filter pattern is formed at a position corresponding to the third sub-pixel, a white filter pattern is formed at a position corresponding to the fourth sub-pixel, and a white filter pattern is formed at a position corresponding to the fourth sub-pixel. , at least one color filter pattern other than black, and the sum of the luminous brightness of the filter patterns of other colors except white and black is not greater than 20% of the luminous luminance of the fourth sub-pixel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display substrate and a display device. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) displays have been widely used in the field of display technology. The basic structure of an OLED display includes an anode, a light-emitting functional layer and a cathode, wherein the light-emitting functional layer is formed of an organic light-emitting material. [0003] There are generally two ways to achieve color display by OLED: one is to use white light organic light-emitting materials combined with color filters to achieve color display; the other is to use high-precision metal masks to evaporate organic light-emitting materials of different primary colors to form colored sub- pixels for color display. [0004] Among them, in the way of using white light organic light-emitting materials combined with color filters to achieve ...
