Problems solved by technology

Among them, the common electrode line cannot be designed too wide and there cannot be no common electrode line. If the common electrode line is designed to be too wide, the light transmittance will be affected.
On the other hand, if the design of the common electrode line is too thin, it will often lead to disconnection, which will cause defects such as weak lines when the LCD panel displays images, resulting in scrapping

Embodiment Construction

[0034] In order to further explain the technical means and effects that the present invention takes to achieve the intended purpose of the invention, the specific implementation and structure of the liquid crystal panel and its common electrode line repair method proposed in the present invention will be described below in conjunction with the accompanying drawings and preferred embodiments. , features and their effects are described in detail below. For convenience of description, in the following embodiments, the same elements are denoted by the same numbers.

[0035] Please refer to FIG. 1, which is a schematic diagram of a liquid crystal panel 100. If a common electrode line of the liquid crystal panel 100 is broken, when the liquid crystal panel 100 displays a picture, the common potential cannot be supplied to the common electrode line after the broken line. Therefore, a weak line 110 is displayed on the screen (or called the display area) 102 . It should be understood ...

Abstract

The invention relates to a repairing method for a common electrode line of a liquid crystal display panel and at least includes the following steps: first, the liquid crystal display panel is checked so as to look for a breaking place of a first common electrode line; then an information line is cut off to form a jumper which crosses the first common electrode line and a second common electrode line which is adjacent to the first common electrode line; and then, a laser welding process is operated to electrically connect the jumper with the first common electrode line and the second common electrode line. Furthermore, the method also provides a structure of the liquid crystal display panel after repairing which leads the liquid crystal display panel to display images without having weak lines, thus enhancing the manufacturing yield rate of the liquid crystal display panel.

Description

technical field [0001] The invention relates to a liquid crystal panel and its repairing method, in particular to a repairing method of common electrode lines of the liquid crystal panel and the repaired liquid crystal panel. Background technique [0002] With the continuous increase of digital information and multimedia applications, as well as the promotion of the world's major display manufacturers, liquid crystal displays (LCDs) are rapidly penetrated into every family and individual, and human beings are very much looking forward to high-quality image displays. . From the traditional heavy cathode ray tube display (CRT) to the direction of thinner thickness, smaller size, lighter weight, better image quality, etc., these goals are also the mainstream trend of displays. [0003] Since the liquid crystal panel has a plurality of common electrode lines electrically connected to a common electrode, it can be used to control the inversion of the liquid crystal. Wherein, th...
