Point defects repairing method of lcd device

Abstract

The invention relates to a point defect repair method of a liquid crystal display device. The liquid crystal display device comprises a plurality of data wires, transistors respectively correspondingly connected with the data wires, and pixel electrodes connected with the transistors. The point defect repair method comprises the following steps: one layer of bus bars is coated among sub-pixels positioned in point defects, and sub-pixels which are adjacent to the sub-pixels; and the connection between the data wires and the pixel electrode of the sub-pixels positioned in the point defects is separated. The point defect repair method can repair luminous point defects and dark point defects into normal display points and can simultaneously complete the repair of a plurality of point defects.

Description

technical field [0001] The invention relates to a method for repairing point defects of a liquid crystal display device, in particular to a repair method capable of repairing point defects into normal display points. Background technique [0002] The liquid crystal panel is composed of many display points, and the liquid crystal material on each display point changes the amount of light transmitted under the control of electrical signals to form an image. For example, there are 786,432 display points in a liquid crystal panel with a resolution of 1024×768. On the side of the array substrate of the liquid crystal display panel, each display point corresponds to three pixels; The side corresponds to the three filter units of red R, green G and blue B respectively. Each filter unit corresponds to a pixel. Any problem in the dots in the LCD panel and the structure of the driving components and backlight components corresponding to these points will cause this pixel to become a...

Problems solved by technology

[0005] In addition, although LCDs with less than 3 bright / dead pixels are within the allowable range, more and more consumers will not be willing to buy a LCD with several bright / dead pixels. monitors, so it is generally difficult for LCD manufacturers with bright / dead pixels to sell at present. In order to obtain profits, some manufacturers will not abolish these LCD screens. In most cases, these panels use a professional equipment to perform Treat dark spots to make them more acceptable

[0006] The method for repairing point defects of liquid crystal panels in the prior art mainly has the following disadvantages: bright point defects can only be repaired into dark point defects; dark point defects cannot be repaired basically; it is difficult to repair continuous point defects, such as continuous bright point defects Defects fixed as continuous dark spot defects are still out of specification
