Problems solved by technology

However, in the manufacturing process of the thin film transistor array substrate, after the two pixel electrodes in a single pixel are patterned, it is very likely that the two pixel electrodes will be short-circuited due to ITO residue and the pixel display will be abnormal.

Embodiment Construction

[0056] figure 1 It is a top view of an active device array substrate according to an embodiment of the present invention. Please refer to figure 1 The active device array substrate 100 of this embodiment includes a substrate 110 , a plurality of scan lines 120 , a plurality of data lines 130 , a plurality of shared line patterns 140 independent of each other, and a plurality of pixels 150 . Wherein, the scan lines 120 , the data lines 130 and the shared line patterns 140 are all disposed on the substrate 110 , and the pixels 150 are arranged in an array on the substrate 110 . Depend on figure 1 It can be seen that each pixel 150 is electrically connected to the corresponding scan line 120 and data line 130 , and the shared line pattern 140 is distributed under each pixel 150 . In addition, each pixel 150 includes a plurality of active devices 152 and a plurality of pixel electrodes 154 . Each pixel electrode 154 is electrically connected to the corresponding scan line 120 ...

Abstract

The invention relates to an active element array substrate, which comprises: substrate, several scanning wires, several data lines, several independent share line pictures, and several pixels, wherein the scanning line, data line and share line picture are on the substrate, and the pixel array is above the substrate, while each pixel is connected to relative scanning line and data line; the share line picture is under each pixel; each pixel comprises several active elements and several pixel electrodes; each pixel electrode via different active elements is connected to relative scanning line and data line; the capacitor couple effects between pixel electrode and share line picture are different. And the invention also provides a relative testing method of said active element array substrate and a liquid crystal display with said active element array substrate.

Description

technical field [0001] The present invention relates to a detection method, and in particular to a detection method capable of effectively detecting short defects (short defects) between a plurality of pixel electrodes inside a single pixel. Background technique [0002] At present, the market is oriented toward high contrast, no gray scale inversion, high brightness, high color saturation, and fast response for TFT-LCDs. ) and wide viewing angle (viewing angle) and other directions. Currently common wide viewing angle technologies include: twisted nematic liquid crystal (TN) plus wide viewing film (wide viewing film), in-plane switching (In-Plane Switching, IPS) liquid crystal display, fringe field switching (Fringe Field Switching) , FFS) liquid crystal display and multi-domain vertical alignment (Multi-doma in Vertical Alignment, MVA) liquid crystal display. Taking the multi-domain vertical alignment liquid crystal display panel as an example, some alignment patterns, s...
