Problems solved by technology
In this case, for the process, the process of film formation, exposure, development, etching, and stripping will be added to form the graphic layer of the repair lead, and the production time and cost will increase; for the product, the repair lead will be increased. Graphics, the effective display area of the pixels will become smaller, the transmittance will decrease, and the brightness of the display will be affected, and the display quality will decrease

Embodiment Construction
[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] like image 3 and Figure 4 As shown, on the color filter side substrate above the intersection of signal one lead 1 and signal two lead 2 on the array substrate side, there is a color filter side substrate glass 8 as a substrate, and on the glass are: a black light shielding layer with light shielding properties, A conductive ITO (indium tin oxide) layer pattern and a conductive columnar support 3 (column Spacer). The main component of the above-mentioned conductive columnar support 3 is a polymer resin with certain elastic and plastic deformation functions. The polymer resin is a material with high resistivity, and the resistivity is above 10000 ohm / cm. In order to improve its conductivity, a certain proportion of conductive substances such as conductive carbon black, conductive fiber, metal powder, and additives are added t...

Abstract
The invention relates to a signal lead restoration technology of a liquid crystal display (LCD), in particular to a signal lead restoration structure of the LCD and a restoration method thereof. The invention adopts a technical proposal that electroconductive prismatical struts are arranged above the cross part of a first signal lead and a second signal lead and below an ITO layer. In the sub-pixel restoration method of the prior art, namely the lead restoration method, a graph provided with restoration function is generally required to be added on the array substrate, thus causing the problems of increasing technique, raising cost, decreasing the luminance of the product and the like. After adopting the new structure of sub-pixel restoration by the color membrane side graph, the bad display phenomenon caused by the break of the signal lead can be reduced effectively, the yield is increased; furthermore, the technique is not increased, the cost can be decreased while the luminance of the product does not descend.
Description
technical field [0001] The invention relates to a repairing technology for signal leads of a liquid crystal display, in particular to a repairing structure and a repairing method for a signal lead of a liquid crystal display. Background technique [0002] Traditional CRT monitors rely on cathode ray tubes to emit electrons and strike phosphors on the screen to display images, but liquid crystal displays work on a completely different principle. Generally, a liquid crystal display (LCD) device has an upper substrate and a lower substrate spaced apart from each other and facing each other. A plurality of electrodes formed on the two substrates face each other. The liquid crystal is sandwiched between the upper and lower substrates. A voltage is applied to the liquid crystal through the electrodes on the substrate, and then the alignment of the liquid crystal molecules is changed according to the applied voltage to display images. Because the liquid crystal display device doe...
