Thin film transistor array base board and its repairing method

Abstract

The basal plate of film transistor array includes following parts: multiple gated scanning wires extended along first direction; multiple data wires extended along second direction, pixel area formed between crossed gated scanning wires and data wires; thin film transistors and pixel electrodes setup inside pixel area; being distributed on two sides of data wires, inner and outer sided shading wires formed on same metal layer to the gated scanning wires; there is at least one lug at one end of the outer shading wire or data wire, and the lug makes overlap between data wire and outer sided shading wire; the other end of outer sided shading wire and one end of repairing wire crossing gated scanning wire are overlapped; the other end of the repairing wire and the repairing pad overlapped with gated scanning wire are overlapped. The invention can be in use for repairing defects of open circuit and short circuit of data wires.

Description

technical field [0001] The invention relates to an array substrate and a repair method thereof, in particular to a thin film transistor array substrate for a liquid crystal display capable of repairing open circuit or short circuit of a data line and a repair method thereof. Background technique [0002] Thin film transistor liquid crystal display (TFT-LCD) panels use thin film transistors (TFT) to control the orientation of liquid crystal molecules to control the intensity of light transmission to display images. A complete TFTLCD panel usually includes a backlight module, a polarizer, a lower substrate of a TFT array, an upper substrate of a CF (color filter), a layer of liquid crystal molecules sandwiched between the upper and lower substrates, and a driving circuit. The display area on the TFT array substrate includes a plurality of sub-pixel areas, and each sub-pixel area is generally a rectangular or other shaped area formed by the crossing of two gate scanning lines a...

Problems solved by technology

However, the above technology has its disadvantages. This technology can only repair the open circuit of the data line in the pixel interval. If the open circuit occurs at the junction of the data line and the gate scanning line or a short circuit occurs on the data line, it cannot be repaired.
