Problems solved by technology

But these solutions can seriously affect the quality of the display panel
For example, the solution of increasing the distance between the pixel electrode and the data line will lead to a decrease in aperture ratio, which not only reduces the transmittance of the display panel, but also restricts the improvement of resolution
As another example, the solution of increasing the thickness of the insulating layer between the pixel electrode and the data line will increase the difficulty of preparing the via hole, reduce the reliability of the connection between the pixel electrode and the drain electrode, and cause the risk of disconnection, and also reduce the display to a certain extent. panel transmittance

Abstract

The embodiment of the invention provides an array substrate and a preparation method thereof, and a display panel. The array substrate comprises a first electrode, a first insulation layer, a data line, a second insulation layer and a second electrode which are arranged on the substrate in order; two sides of the data line are provided with isolation via holes, and the second electrode is connected with the first electrode through the isolation via holes. A shielding electrode connected with a common electrode is arranged and shielding walls are formed at two sides of the data line to shield the capacitance coupling effect between the pixel electrode and the data line and eliminate the pixel voltage abrupt change caused by the coupling capacitance between the data line and the pixel electrode to the most extent. The array substrate and the preparation method thereof, and the display panel are simple in preparation process, low in production cost and convenient to implement.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an array substrate, a preparation method thereof, and a display panel. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD) is the current mainstream flat panel display panel, which has the advantages of light weight, small size, low power consumption, no radiation, and high display resolution. The main structure of TFT-LCD includes an array substrate and a color filter substrate in the box. On the array substrate, gate lines, data lines, and thin-film transistors and pixel electrodes arranged in a matrix are formed. Control signals applied on the gate lines make the data lines The signal voltage of the signal is transmitted to the pixel electrode, and the voltage is provided to the common electrode at the same time, so that the common electrode and the pixel electrode form an electric field, and the arrangement direction of the liquid crystal mole...
