Problems solved by technology

[0003] There are some opaque metal reflective electrodes or metal traces in the OLED device. When the user uses the OLED device outdoors, the sunlight in the outdoor environment reflects more seriously on the metal reflective electrodes or metal traces. OLED devices display low contrast and visibility in outdoor environments

Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel includes a plurality of organic light emitting structures and pixel defining layers, wherein the pixeldefining layers are located between the adjacent organic light emitting structures; The pixel defining layer includes a photochromic material that is darker in color when irradiated with external light than when irradiated without external light and that is used to absorb external light irradiated on the pixel defining layer. The pixel defining layer includes a photochromic material that is darker in color when irradiated with external light than when irradiated without external light and is used to absorb external light irradiated on the pixel defining layer. According to the technical proposal of the invention, so that the external light can be absorbed by the pixel limiting layer containing the photochromic material, the contrast and the visibility of the display panel are improved when the display panel is displayed in an outdoor environment without increasing the thickness of the display panel, and the normal light emission of the organic light-emitting structure in the display panel is not affected, that is, the display effect of the display panel is not affected.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] OLED, Organic Light-Emitting Diode (Organic Light-Emitting Diode), also known as organic electroluminescent device, its basic structure includes an anode, cathode and light-emitting functional layer corresponding to each pixel area, when the voltage is applied to the anode and cathode At this time, the holes move to the light-emitting functional layer through the hole transport layer, and the electrons move to the light-emitting functional layer through the electron transport layer. Due to its many advantages such as self-luminescence, low driving voltage, high luminous efficiency, short response time, high definition and contrast, OLEDs have been used more and more widely. [0003] There are some opaque metal reflective electrodes or metal traces in the OLED device. When the user use...
