Data line maintenance method and array substrate

Abstract

The invention discloses a data line maintenance method and an array substrate, and belongs to the technical field of display. The method includes the following steps that the position at which one data line is disconnected in the array substrate is determined; by means of common electrode lines of the array substrate, first sub data lines and second sub data lines are connected, the first sub data lines are connected with first connection points of the common electrode lines, and the second sub data lines are connected with second connection points of the common electrode lines, the common electrode lines and other common electrode lines except sub common electrode lines are disconnected, and the sub common electrode lines are sections, located between the first connection points and the second connection points, of the common electrode lines. By means of common electrode lines spread over the array substrate, the disconnected data lines are connected, the common electrode lines used for connecting the data lines are made to be disconnected with other common electrode lines, and the problem that in a related technology, a connection line is formed by a CVD and thus the aperture ratio of the array substrate is likely to be reduced is solved. The effect of repairing the data lines without affecting the aperture ratio of the array substrate can be achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a data line maintenance method and an array substrate. Background technique [0002] A display panel generally includes a color filter substrate, an array substrate, and a liquid crystal layer disposed between the two substrates. A thin-film transistor (English: Thin-film transistor; TFT for short) array is arranged on the array substrate, and the thin-film transistor array includes TFTs arranged in an array, wherein each TFT includes a source, a drain, and a gate, and each column of TFTs The gate can be connected to a data line, and the gate of each row of TFTs can be connected to a gate line. When a data line in the array substrate is disconnected, the array substrate cannot work normally. [0003] In the related art, when repairing the data line, the position of the disconnection of the data line is firstly determined, and then a metal wiring line is formed on the array sub...
