Abstract:
A TFT-LCD capable of repairing discontinuous lines includes a repairing circuit, which includes a plurality of repairing OP amplifiers and a high-impedance detecting unit. The high-impedance detecting unit detects states of input terminals of the OP amplifiers. The high-impedance detecting unit enables a control signal to enable the OP amplifier when the input terminal is not at floating state. The high-impedance detecting unit disables the control signal to disable the OP amplifier when the input terminal is at floating state, so that no output competition between the OP amplifiers is generated.
