AI Technical Summary

Problems solved by technology

However, such a design has a disadvantage. If at least one of the two contact holes is not penetrated due to a defect in the manufacturing process, the intended wiring cannot be used as a backup line for the scan wiring or the data wiring after they are broken.
Therefore, as long as it is found that one of the two contact holes is not penetrated, the contact hole must be penetrated by laser repair, and the laser repair has the problem of increasing the impedance.

Abstract

The drawing structure is suitable configured on a base plate. For example, more than three contact holes are formed on dielectric layer between scanning data wires and scanning data quasi wires so as to make electrical connection between scanning data wires and scanning data quasi wires. When the said contact holes are not all passed through, signals are still can be transferred through scanning data quasi wires.

Description

technical field [0001] The present invention relates to a pixel structure (pixel), in particular to a pixel structure capable of avoiding contact holes not being penetrated due to process defects, that is, failure of intended wiring. Background technique [0002] In order to match the modern life style, the volume of video or image devices is becoming thinner and lighter. Although the traditional CLD still has its advantages, it needs to occupy a large volume and consumes a lot of power. Therefore, in combination with optoelectronic technology and semiconductor manufacturing technology, panel-type displays have been developed into common display products, such as liquid crystal displays (LCDs). [0003] The liquid crystal display is mainly composed of an active element array substrate, a color filter array substrate and a liquid crystal layer, wherein the active element array substrate is composed of a plurality of pixel units arranged in an array. The pixel unit is mainly...
