Problems solved by technology

When a certain area of ​​the existing OLED displays a static image for a long time, the light-emitting layer in this area will be in a state of emitting light for a long time. Due to the material properties of the light-emitting layer, the display brightness of this area will gradually decrease, resulting in afterimages in this area. The problem

Embodiment Construction

[0022] The specific implementation manners of the array substrate, the driving method, the organic electroluminescent display panel and the display device provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] An array substrate provided by an embodiment of the present invention includes: a base substrate and a plurality of pixels arranged in a matrix on the base substrate; each pixel is composed of four sub-pixels with different color resists arranged in two rows and two columns ; figure 1 5 pixels are shown, each sub-pixel in one pixel is represented by A1, B1, C1, D1 respectively, and each sub-pixel in the next pixel is represented by A2, B2, C2, D2 respectively, and so on, wherein, A1 And A2, B1 and B2, C1 and C2, D1 and D2 can represent any color in RGBW, RGBY or RGBC;

[0024] In the predetermined area of ​​the array substrate, each pixel is divided into a group with three adjacent co...

Abstract

The invention discloses an array substrate, a driving method, an organic electroluminescence display panel and a display device. A color resistance arrangement method of all sub pixels in adjacent-row pixels in at least one group of three adjacent rows of pixels in the array substrate is changed to enable the color resistance colors of two adjacent-row sub pixels belonging to two different pixels to be identical. Therefore, in each row of pixels in each group of pixels, assumed that two sub pixels with same adjacent-row color resistance color form a sub pixel unit and four sub pixel units with different color resistance colors form a pixel unit, in each pixel unit, the number of the sub pixels with the same color resistance color is two, and when a static image is displayed for a long time in a preset region of the organic electroluminescence display panel, each sub pixel in the region can have restoring time by driving the two sub pixels with the same color resistance color in each pixel unit in turns, so that the problem of residual image in the preset region of the organic electroluminescence display panel can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a driving method, an organic electroluminescence display panel and a display device. Background technique [0002] Among existing flat panel display devices, organic electroluminescent display devices (Organic Electroluminescent Display, OLED) have gradually become the mainstream in the display field due to their characteristics of low power consumption, high color saturation, and wide viewing angle. [0003] Existing OLEDs generally include a substrate, an organic electroluminescent structure located on the substrate, and an encapsulation film covering the outside of the organic electroluminescent structure; where the organic electroluminescent structure includes successively An anode, a light-emitting layer, and a cathode are stacked. When a certain area of ​​the existing OLED displays a static image for a long time, the light-emitting layer in thi...
