Line repairing structure, repairing method and liquid crystal display panel

Abstract

The invention provides a line repairing structure, a repairing method and a liquid crystal display panel. The line repairing structure is adaptive to being configured on a board. The line repairing structure includes at least a repairing line, at least a signal line, a first dielectric layer and a repairing area. The first dielectric layer is configured between the signal line and the repairing line. The second dielectric layer covers on the first dielectric layer, the signal line and the repairing line, wherein the second dielectric layer has a first opening, the first opening exposes the repairing area and the area of the first opening is larger than that of the repairing area. The line repairing structure can prevent the dielectric layer warpage and the metal residue splashing owing to repairing so as to avoid the short circuit due to contact of the repaired signal line and an electrode layer on an opposite board owing to the metal residues, thereby the repaired display panel has the good display quality.

Description

technical field [0001] The invention relates to a repairing circuit structure, a repairing method and a liquid crystal display panel, and in particular to a repairing circuit structure, a repairing method and a liquid crystal display panel capable of achieving a good repairing effect. Background technique [0002] The operation mode of the flat panel display is to control each pixel (pixel) arranged in an array by two sets of addressing lines perpendicular to each other, so as to achieve the purpose of displaying images. Among various display control modes, the design of scan lines and data lines is most commonly used. These scan lines and data lines are perpendicular to each other and define a plurality of pixels. Each scanning line is sequentially turned on to turn on or turn off the corresponding switching element, so that the signal transmitted by each data line can be written into the pixel, thereby changing the state of the corresponding pixel, and achieving the purpos...

Problems solved by technology

It should be noted that the repair external force may cause the dielectric layer 140 above the signal line 120 to warp toward the opposite substrate 150 (eg Figure 1B and Figure 1C shown), and the metal debris 128 of the melted signal line 120 or the repair line 112 may splash onto the warped dielectric layer 140

In this way, when the display panel is pressed due to testing or other reasons, the electrode layer 152 on the opposite substrate 150 may come into contact with the metal residue 128 on the dielectric layer 140, thereby causing the signal line 120 to contact the electrode layer 152. Short circuit, which makes the display quality of the display panel deteriorate
