Abstract

This invention discloses an active element array base board, which scanning line and data line are configured on the display region of the base board and divide it into multiple pixel regions, the switch elements are configured on the pixel regions and connected with the scanning lines and the data lines electrically, pixel electrodes are set on the pixel regions and connected with related switch elements electrically, routings are configured on a non-display region of the base board, each of the routings includes a first and second conductor layers, in which, the second one is set on the first one and parallel to the first one, which is on a same membrane layer with the scanning line, the data line or the pixel electrode and the second conductor layer is on a same membrane layer with the other of the scanning line, the data line or the pixel electrode so as to reduce the impedance difference among routings on the non-display region.

Description

Technical field [0001] The invention relates to an element array substrate, and more particularly to an active element array substrate. Background technique [0002] As the demand for displays is increasing day by day, the industry is fully committed to the development of related displays. Among them, Cathode Ray Tube (CRT) has monopolized the display market for many years because of its excellent display quality and technological maturity. However, due to the recent rise of the concept of green environmental protection, its characteristics of large energy consumption and large radiation output, coupled with the limited space of its products, can not meet the market’s requirements for light, thin, short, small, beautiful and low consumption. Market demand for power. Therefore, TFT LCD (Thin Film Transistor Liquid Crystal Display) with superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation has gradually becom...
