Abstract

The present invention provides a display panel and a display device and relates to the technical field of display. By partially absorbing light with higher brightness, three stimulus values X, Y, andZ of a display screen of the display panel are balanced to further improve the color shift phenomenon of an OLED panel. The display panel includes a substrate and a plurality of pixel units arranged on the substrate. Each of the pixel units comprises a first OLED device, a second OLED device and a third OLED device. The first OLED device emits first color light, the second OLED device emits secondcolor light, and the third OLED device emits third color light. Each of the pixel units also comprises a light absorbing layer for absorbing a part of the light of the first color light emitted by the first OLED device and/or a part of the light of the second color light emitted by the second OLED device, and the brightness of the first color light and the second color light is larger than the brightness of the third color light emitted by the third OLED device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) device is a device that uses an electric field to act on organic materials to emit light. It has many advantages such as high contrast, short response time, and can be applied to ultra-thin flexible display products. [0003] With the rapid development of OLED display technology, while meeting the individual needs of users, some problems have also been exposed. Among them, the color deviation of the white screen of the OLED display panel under different viewing angles is one of the main reasons restricting the further development of the OLED display technology, which seriously affects the user experience. [0004] The principle of color deviation (referred to as color deviation) is as follows: The International Commission on Illumination (CIE) theoretically assumed th...
