Embodiment Construction

[0020] The specific implementation manners of an array substrate and a display device provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the described embodiments are only some of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] The inventor found in research that the array substrate includes pixel units P arranged in an array, and each pixel unit P includes at least two sub-pixel units P0 with different colors, such as figure 1 As shown in , each pixel unit P includes three sub-pixel units P0, which are red sub-pixel unit R, green sub-pixel unit G, and blue sub-pixel unit B. By separately controlling each sub-pixel unit P0, And dif...

Abstract

The invention discloses an array substrate and a display device, and relates to the technical field of display. In the embodiment of the invention, A current adjusting structure is added. According tothe current light-emitting brightness of the correspondingly connected light-emitting device, The driving current output to the light-emitting device is adjusted, so that the current light-emitting brightness of the light-emitting device is adjusted, the light-emitting brightness of the light-emitting device is kept stable, the ghost shadow problem caused by unstable light-emitting brightness ofthe light-emitting device is avoided, and the display effect is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an array substrate and a display device. Background technique [0002] Displays include liquid crystal displays and electroluminescent displays. Among them, liquid crystal displays, as the name implies, include liquid crystals. To realize the display function, the backlight provided by the backlight module is needed, so the liquid crystal display is a non-self-luminous display; The display is different from the liquid crystal display. The electroluminescent display is a self-illuminating display without a backlight module, so the electroluminescent display can be made thinner and lighter. Moreover, the electroluminescent display also has advantages in terms of display contrast. Big advantage. [0003] However, for an electroluminescence display, if a certain still image is displayed for a long time, image sticking will occur, resulting in a decrease in display effect. Then, ho...
