Abstract

The invention relates to an active component array substrate and a detection method thereof. The active component array substrate is provided with a display area and a peripheral circuit area, and comprises a plurality of pixel units, a plurality of signal conductors, a plurality of detection pads and a first dielectric layer, wherein the pixel units are arranged in an array in the display area; the signal conductors and the detection pads are configured in the peripheral circuit area; and the first dielectric layer is covered on the detection pads. In the detection method of the active component array substrate, first, part of the first dielectric layer is removed to expose the detection pads to be in electrical contact with a detecting tool, i.e., before detection, the detection pads are electrically insulated from the outside, thus preventing static charges from causing static damage to the pixel units through the detection pads and the signal conductors, and improving the circuit stability of the active component 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...
