Active element array substrate and detection method thereof

Abstract

The invention relates to an active element array substrate and a detection method thereof. The active device array substrate has a display area and a peripheral circuit area, and the active device array substrate includes a plurality of pixel units, a plurality of signal wires, a plurality of detection pads and a first dielectric layer. The pixel units are arranged in an array in the display area, the signal wires and the detection pads are arranged in the peripheral circuit area, and the first dielectric layer covers the detection pads. The detection method of the active device array substrate is to firstly remove part of the first dielectric layer to expose the detection pads to be electrically contacted with the detection tool. That is to say, before the detection, the detection pad is electrically insulated from the outside world, so that electrostatic damage to the pixel unit caused by electrostatic charge from the detection pad through the signal wire can be avoided, so as to improve the circuit stability of the active device array substrate.

Description

technical field [0001] The invention relates to an active element array substrate and a detection method thereof, in particular to an active element array substrate capable of preventing static electricity from passing through a detection pad to damage a circuit and a detection method thereof. Background technique [0002] Due to the advantages of small size, light weight and fast response, the active flat display panel has been widely used in various electronic products. The active flat display panel is composed of an active element array substrate, a display layer and a light-transmitting substrate, wherein the display layer is located between the active element array substrate and the light-transmitting substrate, such as a liquid crystal display panel (LCD panel). A liquid crystal layer, an electrophoretic layer of an electrophoretic display panel (EPD panel), etc. [0003] see figure 1 As shown in FIG. 1 , it is a schematic diagram of a known active device array subst...

Problems solved by technology

[0008] It can be seen that the above-mentioned existing active element array substrate and its detection method obviously still have inconveniences and defects in product structure, detection method and use, and needs to be further improved

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure and method for general products and methods to solve the above-mentioned problems. This is obviously a problem that relevant industry players are eager to solve
