Abstract
A display driving circuit includes a light emitting assembly which includes a first control switch having a first terminal connected to a cathode of the light emitting unit, a second terminal connected to a common terminal, and a control terminal connected to a first signal wire to provide a first control signal and a second control switch having a first terminal connected to a charging terminal, a second terminal connected to an anode of the light emitting unit and a control terminal connected to a second signal wire to provide a second control signal. When the light emitting unit is turned off, the first control switch disconnects the cathode of the light emitting unit and the common terminal in response to the first control signal, and the second control switch disconnects the anode of the light emitting unit and the charging terminal in response to the second control signal.
