TFT-LCD (thin film transistor-liquid crystal display) array substrate and test method of TFT-LCD array substrate

Abstract

Provided are a TFT-LCD array substrate and a test method therefor. The array substrate includes a display area and a peripheral region located at the periphery of the display area. The display area is provided therein with gate lines and data lines; the peripheral region is provided therein with: a first test short bar on which are provided a plurality of test lines for separately transmitting a data test signal to each data line in the display area, and a second test short bar on which is provided a gate-line test line for transmitting a gate line test signal to each gate line in the display area; and a connection device (5) containing a first connection layer (50) and a second connection layer (51) is provided at the connection position between at least one data test line of the first test short bar and one data line of the display area, or at the connection position between the gate-line test line of the second test short bar and at least one gate line of the display area. The test method can realize double testing on a TFT-LCD array substrate.

Description

technical field [0001] The present invention relates to a testing technology of a liquid crystal panel, in particular to a thin film transistor liquid crystal display (Thin Film Transistor liquid crystal display, TFT-LCD) array substrate and a testing method thereof. Background technique [0002] TFT-LCD is currently the only display device that has fully caught up with and surpassed the cathode ray tube (Cathode Ray Tube, CRT) display in terms of brightness, contrast, power consumption, life, volume and weight. It has excellent performance, large-scale With the advantages of good production characteristics and high degree of automation, it has quickly become the current mainstream product. The liquid crystal panel in TFT-LCD is composed of thin film transistor array substrate (array substrate), color filter array substrate (CF substrate) and liquid crystal sandwiched between the two substrates. Among them, the Array substrate and the CF substrate are film-formed by chemica...
