Abstract
A repairing structure of an LCD is provided, which includes at least a first conductive layer, an insulating layer located on the first conductive layer, at least a second conductive layer located on the insulating layer, and an opening located on the first conductive layer in a crossing region where the first conductive layer and the second conductive layer are overlapped. A repairing method of the repairing structure is further provided.
Claims11
A repairing structure of a liquid crystal display (LCD), comprising:
- at least a first conductive layer, comprising at least one opening completely surrounded by the first conductive layer;
- an insulating layer, located on the first conductive layer, and covering the opening;
- at least a second conductive layer, located on the insulating layer;
- and
- a crossing region, located at a position where the first conductive layer and the second conductive layer are overlapped, wherein the opening is located in the crossing region to serve as a repairing region.
2 more elements
A repairing method of a liquid crystal display (LCD), comprising:
- providing a first conductive layer and a plurality of second conductive layers, wherein the first conductive layer spans across at least one of the second conductive layer, and the at least one of the second conductive layer has at least a defective second conductive layer, wherein the first conductive layer comprises at least one opening completely surrounded by the first conductive layer;
- and
- providing a laser power, wherein at a crossing region between the defective second conductive layer and the first conductive layer, the opening is located in the crossing region to serve as a repairing region, and the insulating layer above the opening of the first conductive layer is penetrated by the laser power, such that the defective second conductive layer is electrically connected to the first conductive layer, and an electrical signal is delivered between the two conductive layers.
