Abstract

Embodiments of the present invention provide a display panel and a display device, which relate to the field of display, and are used to solve the problem that, in a picture displayed by a display device in a dark background mode in the prior art, the light-colored display content is shifted as the position changes. color issue. The display panel includes a first subpixel displaying a first color, a second subpixel displaying a second color, and a third subpixel displaying a third color. When the picture displayed on the display panel is switched from the black picture to the maximum grayscale picture of the first color, the second color and the third color, the ratio of the brightness of the first frame picture to the maximum brightness of the multi-frame pictures after stabilization is the first The brightness ratio of the first frame, the brightness ratio of the second frame, and the brightness ratio of the third frame. The brightness ratio of the first first frame, the extreme difference between the brightness ratio of the second first frame and the brightness ratio of the third first frame is less than or equal to 20%.

Description

technical field [0001] The present invention relates to the field of display, and in particular, to a display panel and a display device. Background technique [0002] The usage scenarios of display devices (eg, mobile phones, notebook computers, etc.), such as organic light-emitting diode (Organic Light-Emitting Diode, OLED for short) display devices, are becoming more and more diverse. For example, for eye protection and other purposes, when people use smartphones, the use of dark background mode is gradually increasing. In the dark background mode, the displayed picture takes a dark picture as the background and is matched with light-colored display content (the display content may include patterns, text, etc.). [0003] However, when the display mode of the mobile phone is configured as the dark background mode, as the user slides the finger on the screen, the position of the light-colored display content on the screen changes, and the light-colored display content will...
