LCD device array substrate, its defect mending method

Abstract

The invention discloses an LCD device array substrate, which comprises a plurality of gate lines; a plurality of data lines intersecting the plurality of gate lines to define a plurality of pixel regions; pixel electrodes positioned in the pixel regions; gate line layers and data line layers, wherein, the plurality of gate lines and the plurality of data lines are respectively arranged; and a TFT including a source region, a gate, a source and a drain, wherein the gate, the source and the drain are respectively electrically connected with the gate lines, the data lines and the pixel electrodes. The invention also discloses a dot and / or line defect repair method of the LCD device array substrate. A new TFT formed by the repair method of the invention can be used for substituting for a TFT with pixel failure, thus achieving complete repair of dot defect of the array substrate and achieving better display state of the array substrate. The repair method can be also be used for repairing all structures with broken data lines, short-circuit and open-circuit at intersection portions of the data lines and the gate lines as well as dot defects.

Description

technical field [0001] The present invention relates to a liquid crystal display device, more specifically to an array substrate of a liquid crystal display device capable of repairing point defects and / or line defects and a repairing method thereof. Background technique [0002] As a kind of flat panel display, liquid crystal display has been widely used in various fields. Generally, a liquid crystal display has two substrates containing electrodes for generating an electric field, and a liquid crystal layer disposed between the two substrates, and controls the transmission of incident light by controlling the electric field intensity applied to the liquid crystal layer through the electrodes on the two substrates rate, so as to realize the control of the brightness and darkness of the display panel. [0003] FIG. 1 is a schematic diagram of the overall structure of an array substrate of a typical liquid crystal display device. Referring to Fig. 1, a plurality of gate lin...

AI Technical Summary

Problems solved by technology

The disadvantage of this technology is that if point defects and line defects occur at the same time, repair lines must be set up separately, and the process is more complicated

[0008] To sum up, the repair of pixel defects in the prior art is not a complete repair, so there is still a difference between the repaired pixel and the normal pixel, and there is a certain difference in the display effect compared with other normal pixels. deviation, unable to achieve the same display quality as normal pixels

In addition, in the prior art, repairing lines for point defects and line defects are generally set up separately, and it is impossible to use one repairing line to repair line defects and point defects at the same time
