Patent ID: 8120374

Claim:
An inspection circuit for inspecting a plurality of signal wires of a display area, each signal wire having a first end for electrically connecting to a signal driving circuit and a second end, the inspection circuit comprising: a first signal wire shorting switch, comprising: a first end, electrically connected to the first end of a first signal wire of the plurality of the signal wires; a second end; and a third end for receiving a first control signal; wherein the first signal wire shorting switch controls the first end of the first signal wire shorting switch electrically connecting to the second end of the first signal wire shorting switch according to the first control signal; a second signal wire shorting switch, comprising: a first end, electrically connected to the second end of the first signal wire of the plurality of the signal wires; a second end, electrically connected to the second end of a second signal wire of the plurality of the signal wires; and a third end for receiving a second control signal; wherein the second signal wire shorting switch controls the first end of the second signal wire shorting switch electrically connecting to the second end of the second signal wire shorting switch according to the second control signal; and a first shorting bar for receiving a first inspection signal, the first shorting bar being electrically connected to the second end of the first signal wire shorting switch; wherein when the first shorting bar receives the first inspection signal, the first and the second control signals turn on the first and the second signal wire shorting switches respectively at the same time.
