Abstract
A display driving circuit includes a control sub-circuit and a gate drive sub-circuit connected to the control sub-circuit. The control sub-circuit is configured to: receive an effective display data enable signal; determine whether the effective display data enable signal is lost; and control each stage of shift register in the gate drive sub-circuit to output a disabling signal via an output terminal of the shift register in response to determining that the effective display data enable signal is lost.
