Embodiment Construction

[0025] image 3 It is a schematic diagram of the active device array mother substrate in the first embodiment of the present invention. Please refer to image 3 , the active device array mother substrate 300 is suitable for being divided into multiple active device array substrates. Specifically, the active device array motherboard 300 includes a substrate 310 , multiple sets of active device arrays 320 and multiple external circuit pads 350 . Wherein, the substrate 310 may have predetermined regions A, B, C and D, and each group of active device arrays 320 is disposed in the predetermined regions A, B, C and D respectively. That is to say, the active device array mother substrate 300 of this embodiment can be cut into four active device array substrates in a subsequent process. Of course, the present invention is not intended to limit the number of predetermined regions on the substrate 310 , which can be appropriately adjusted depending on the size and number of active de...

Abstract

An active element array mother base board fits for cutting several active element array base boards, the active element mother base board includes a base board, a plurality of active element arrays and a plurality of outer circuit pads. Thereinto, the base board is provided with a plurality of preset areas, each preset area respectively defines a position for an active element array base board. Besides, the active element arrays and outer circuit pads are distributed in the preset areas, and within the preset area, the outer circuit pad and signal wire of the active element array are electrically connected. Especially, at least outer circuit pad in one preset area is electrically connected with outer circuit pad in the other preset area.

Description

technical field [0001] The present invention relates to an active device array mother substrate, and in particular to an active device array mother substrate with electrostatic discharge (electro static discharge, ESD) protection function. Background technique [0002] During the manufacturing process of liquid crystal displays, operators, machines or testing instruments may be charged with static electricity, and when the above-mentioned charged objects (operators, machines or testing instruments) touch the liquid crystal display panel, it may cause the inside of the liquid crystal display panel Components and circuits are damaged by electrostatic discharge (electro static discharge). Therefore, an electrostatic discharge protection circuit is generally designed in the non-display area of ​​the liquid crystal display panel. Taking the active matrix liquid crystal display panel as an example, it usually forms an ESD protection circuit on the substrate during the process of ...
