Abstract
A display driving circuit, including: a first input terminal configured to receive a first signal; a second input terminal configured to receive a second signal; a third input terminal configured to receive a third signal; an output terminal configured to output a gate driver control GIP signal; a voltage detection circuit configured to detect an anomaly of the first signal, the second signal, and the third signal, and produce a detection result to indicate the anomaly; a shift register signal output port configured to output the gate driver control GIP signal to the output terminal; and a control circuit configured to receive the detection result, wherein, when no anomaly is indicated by the detection result, the control circuit controls the shift register signal output port to output the gate driver control GIP signal, and when the anomaly of at least one of the first signal, the second signal or the third signal is indicated by the detection result, the control circuit controls the shift register signal output port to stop outputting.
