Abstract

The invention discloses an active component array substrate which comprises a substrate, an active component array, a detection line, a plurality of drive chip pads, a plurality of flexible circuit pads, a plurality of connection lines and an internal static protective ring, wherein, the active component array and the detection line are allocated on the substrate, and the detection line is electrically connected with the active component array. The drive chip pad and the flexible printed circuit pad are allocated on the substrate, wherein, the drive chip pad is electrically connected with the active component array. These connection lines are allocated on the substrate, and each connection line is respectively connected with any flexible printed circuit pad and detection line. The internal static protective ring is allocated on the substrate and electrically and respectively connected with the active component array and any flexible printed circuit pad. Therefore, the detection line can act as the external static protective ring to reduce line damage possibility due to electrostatic discharge.

Description

technical field [0001] The present invention relates to an element array substrate, and in particular relates to an active element array substrate for a liquid crystal display. Background technique [0002] The multimedia technology in today's society is quite developed, mostly benefiting from the progress of semiconductor components and display devices. As far as displays are concerned, liquid crystal displays with superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation have gradually become the mainstream of the market. [0003] For a TFT-LCD module, it is mainly composed of a liquid crystal display panel and a backlight module. Wherein, the liquid crystal display panel is generally made up of a thin film transistor array substrate (thin film transistor array substrate), a color filter substrate (color filter substrate) and a liquid crystal layer arranged between these two substrates, and the backligh...
