Array substrate, display panel and display device

Abstract

The invention discloses an array substrate, a display panel and a display device. The array substrate comprises a first pixel unit line, ..., an N pixel unit line and connecting units, the pixel unit lines are scanned line by line, each pixel unit line comprises a plurality of pixel units, each pixel unit comprises a pixel electrode, N is an integer which is not less than 2, pixel electrodes corresponding to all the pixel units in the i+1 pixel unit line are electrically connected to form a plurality of pixel electrode groups by the connecting units when the i pixel unit is scanned, each pixel electrode group comprises pixel electrodes with inverse voltage polarity, the number of the pixel electrodes of one pixel electrode group is as same as that of another pixel electrode group, and i is a positive integer which is smaller than N. When the previous pixel unit is scanned, all the pixel electrodes in a next pixel unit line are divided into a plurality of pixel electrode groups, all the pixel electrodes in the pixel electrode groups are electrically connected, the number of the pixel electrodes with inverse voltage polarity of one pixel electrode group is as same as that of another pixel electrode group, so that electric charge of the pixel electrodes in the pixel electrode groups is neutralized, charging time of the pixel electrodes is shortened, and power consumption of the pixel electrodes is reduced.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to an array substrate, a display panel and a display device. Background technique [0002] Liquid Crystal Display (LCD) has the advantages of low driving voltage, low power consumption, high reliability, large amount of displayed information, no flicker, and low cost. It is an ideal display device and has been widely used in people's daily life and work. The liquid crystal display device includes a plurality of pixel units, and each pixel unit includes a pixel electrode, wherein, by charging each pixel electrode, the deflection of the liquid crystal molecules is driven to achieve the purpose of emitting light from the corresponding area of ​​each pixel unit, and then The liquid crystal display device displays a screen. In the process of charging the pixel electrode, since the charging polarity needs to be reversed in each frame, when the next frame is displayed, ...

AI Technical Summary

Problems solved by technology

In the process of charging the pixel electrode, since the charging polarity needs to be reversed in each frame, when the next frame is displayed, after the residual charge in the pixel electrode needs to be neutralized in the previous frame, The pixel electrode can be effectively charged, which makes the power consumption of the display device larger, and prolongs the charging time of the pixel electrode, reducing the screen refresh rate of the display device.
