Abstract

The invention discloses a display panel and a display device, the display panel comprises a plurality of first color sub-pixels, and the first color sub-pixels comprise first color sub-pixels A and first color sub-pixels B; the display panel at least comprises a low-gray-scale picture during display, and when the display panel displays at least part of the low-gray-scale picture, the low-gray-scale picture comprises a first stage and a second stage, the first color sub-pixels A of the first stage have initial brightness, and the first color sub-pixels B of the first stage have initial brightness; in the second stage, the first color sub-pixels A have first brightness, and the first color sub-pixels B have second brightness; the first brightness is less than the second brightness, the firstbrightness is less than the initial brightness of the first color sub-pixel A, and the second brightness is greater than the initial brightness of the first color sub-pixel B; the gray value range ofthe low gray scale is greater than or equal to 0 and less than or equal to X, and X is a positive integer. According to the invention, the phenomenon of uneven display of the display panel during low-gray-scale display is effectively improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] OLED (Orgmnic Light-Emitting Diode, Organic Light-Emitting Diode), as a current-mode light-emitting device, has been increasingly used in high-performance displays. Due to its self-luminous characteristics, it has many advantages compared with LCD, such as high contrast, ultra-thin, and bendable. [0003] In an OLED device, due to the nature of the material itself, the hole mobility of the hole injection layer is very high, and the material of the hole injection layer can conduct electricity in both lateral and vertical directions. An OLED device includes pixels of three colors of red, green and blue, and the lighting voltages of pixels of different colors are different. When the pixels of the color with higher operating voltage are lit, due to the influence of crosstalk current or thin film t...
