a wiring structure

Abstract

The invention discloses a wiring structure, which is applied to TFT-LCD (thin film transistor liquid crystal display) array substrate, wherein the substrate has a pixel region, a wiring region, a terminal region and a TFT array; the pixel region is limited crossly by a plurality of scanning lines and a plurality of data signal lines; the wiring region and the terminal region are arranged on the outer side of the pixel region; the TFT array is formed on the substrate and is arranged in the pixel region; the wiring region comprises a plurality of first wires formed by first wiring layers and a plurality of second wires formed by second wiring layers; the first wires and the second wires are alternatively configured, and a shielding electrode is arranged between each first wire and each second wire; the first wires and the second wires electrically connect a plurality of pixel terminals with a plurality of signal terminals. Through the scheme of the invention, the problem of wire width and wire distance easily generated in a single-layer metal wire is solved through the double-layer wire; meanwhile, an ITO (indium tin oxide) transparent electrode arranged between the two adjacent wires is used for isolating signal interference, so that the problem that the display quality is influenced by the signal interference between the two layers of wires is solved.

Description

technical field [0001] The invention relates to a wiring structure, in particular to a double-layer wiring structure of a TFT-LCD array substrate. Background technique [0002] With the development of the Thin Film Transistor Liquid Crystal Display (TFT-LCD) industry and the increasing demands of consumers, thinner and thinner LCD displays with beautiful appearance and sharp feeling have become a popular trend. At the same time, the reduction of ICs for LCDs and the design requirements of Fine Pith COF (Chip on Film) \ COG (Chip on Glass) are also increasing the requirements for narrow frontal margins of LCDs. [0003] The main factor affecting the determination of the narrow frame is the wiring area of ​​the TFT-LCD array substrate of the liquid crystal display, such as figure 1 Shown is a partial schematic diagram of a liquid crystal display TFT-LCD array substrate in the prior art. The surface of the substrate 100 has a pixel area P (ie, a display area), a wiring area L ...
