Organic light emitting diode (OLED) display substrate and OLED display device

Abstract

The present invention provides an OLED display substrate and an OLED display device, relates to the display technology field, and solves the problems that for adjusting the chromaticity coordinate or color temperature balance, the conventional OLED display device drives other sub pixels, so that the driving is complicated, and the power consumption is large. The OLED display substrate comprises a colorized filter layer, and the colorized filter layer comprises the filter patterns of at least four different colors, wherein the display substrate forms a red filter pattern at the position corresponding to a first sub pixel, forms a green filter pattern at the position corresponding to a second sub pixel, forms a blue filter pattern at the position corresponding to a third sub pixel, and forms a white filter pattern and a filter pattern of at least one other color except the white and the black at the position corresponding to a fourth sub pixel, and the light emitting brightness sum of the filter patterns of other colors except the white and the black is not greater than 20% of the light-emitting brightness 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 ...
