Patent ID: 8351009

Claim:
A drive-circuit where a flexible circuit-mounted board is connected physically and electrically to a display panel and a wiring-mounted board to form a first circuit, wherein: the wiring-mounted board has a first test wiring section, comprising first and second terminals, first and second wires, and a first common wire; the flexible circuit-mounted board comprises a semiconductor-integrated circuit that outputs drive signals for driving a display panel, supply wiring that is connected to the semiconductor-integrated circuit, and a third and fourth wire which extend toward the display panel and the wiring-mounted board; the display panel comprises a plurality of spaced short-circuit wires disposed along an edge of the display panel which extend toward the flexible circuit-mounted board; wherein the plurality of spaced short-circuit wires of the display panel connect to the first test wiring section of the wiring-mounted board through the third and fourth wire of the flexible circuit-mounted board; wherein said supply wiring supplies, to the semiconductor-integrated circuit, signals causing the semiconductor-integrated circuit to output the drive signals, wherein a current may be induced in the first circuit between the first and second terminals, travelling through the first wire, the third wire, a plurality of spaced short-circuit wires, the first common wire, the fourth wire, and the second wire, where an unexpectedly high resistance indicates a degradation in said connection between the wiring-mounted board and the display panel.
