Array substrate, manufacturing method of array substrate and display appliance

Abstract

The invention discloses an array substrate, which comprises a substrate, and a grid line and a data line which are arranged on the substrate; the grid line and the data line are intersected to be a pixel unit aligned in a matrix form; an oxide thin film transistor, a pixel electrode, a public electrode, and a first insulation layer situated between the pixel electrode and the public electrode arearranged in every pixel unit, wherein the pixel electrode and the public electrode in adjacent pixel units are reversed to each other, and the pixel electrode in every pixel unit is connected with thegrid line and the data line through corresponding oxide thin film transistor; the public electrode in every pixel unit is connected to the same public signal line. The invention further provides a manufacturing method of the array substrate and a display appliance. The pixel electrode and the public electrode in adjacent pixel units are reversed to each other, the public electrode in every pixelunit is connected to the same public signal line, thus the point reversion can be realized through frame reversion; meanwhile, the power consumption is reduced and the picture quality is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a manufacturing method of the array substrate and a display device. Background technique [0002] With the rapid development of electronic products towards lightness, thinness and miniaturization, almost all kinds of portable electronic products use liquid crystal displays (Liquid Crystal Display, LCD) as display panels, especially in camcorders, notebook computers, desktops, etc. In products such as computers, smart TVs, mobile terminals or personal digital processors, liquid crystal displays are already an important component. [0003] During the display process of the liquid crystal display, the driving voltage of the liquid crystal molecules cannot be fixed at a certain value, otherwise the liquid crystal molecules will be polarized due to the accumulation of positive and negative charges, and gradually lose their optical rotation characteristics....

AI Technical Summary

Problems solved by technology

There are four common polarity conversion methods: frame inversion, row inversion, column inversion, and dot inversion. Among them, frame inversion means that the entire display is refreshed by positive voltage in the previous frame, and the next frame is refreshed by negative voltage. Voltage refresh, row inversion refers to the polarity conversion process that the odd-numbered rows of a frame of image are positively voltaged and the even-numbered rows are negatively voltaged in the previous frame, and the voltage polarity of the odd and even rows is reversed in the next frame. Similar to line inversion, dot inversion means that the voltage polarity of adjacent pixels in each frame of image is opposite. The dot inversion method is beneficial to eliminate crosstalk and screen flicker, so the image quality is the best, but due to dot inversion Invert every two points as a unit, and the power consumption is relatively high compared to other conversion methods
