Abstract

This invention uses a combined circuit to inspect layout in the fabrication of TFT matrix of display panels. In the past, designs of different circuit layouts for inspection are needed for different inspection machines. This invention is designed to use plural circuit switches and connecting wires to introduce a short-ring layout and a shorting-bar layout, or use a multiplexer as well as plural circuit switches and connecting wires to introduce a short-ring layout and a shorting-bar layout. This invention allows switching and selection of various inspection methods via the plural circuit switches, so as to increase utilization rate of the equipment and to reduce cost.
