    Abstract: An LCD panel testing method. The method comprises forming jump lines in a predetermined region on the substrate between the signal lines via mask design when forming TFT LCD arrays, and thus forming a plurality of signal-line groups each with two signal lines coupled by the jump lines. Thereupon, an array tester sequentially tests two pixels corresponding to the signal lines in the signal groups. If one of the feedback signals from the signal groups does not meet a predetermined standard, it is determined that one or both pixels in the signal group are defective. The defective pixel or pixels are then identified using an electronic microscope to test two pixels at the same time. In this way, the number of probe pins and tests performed is halved. The probe pin size is also thus less restrictive due to larger probe pin intervals. Consequently, yield is greatly increased.

    Abstract: A TFT array substrate and a process for manufacturing the same are provided. A plurality of TFTs in array are formed on a substrate. A gate insulating layer and a protection layer are sequentially formed to cover a pixel region of the substrate. A plurality of openings each of which has an undercut profile are formed in the gate insulating layer and the protection layer. Then, a transparent conductive layer is formed over the substrate. One of the two parts separated is located in a bottom of the opening and the other is on the protection layer, such that two parts of the transparent conductive layer disconnect and no junction there between occurs. The part of the transparent conductive layer in the bottom of the opening is referred to as a transparent pixel electrode. The part of the transparent conductive layer on the protection layer is connected to a common metal line to form a transparent common electrode. The transparent pixel electrode disconnects to but overlaps the protection layer
