Abstract
A shading signal generating circuit includes an output port, a first switch, a second switch, a third switch, a first control unit, a second control unit, and a resistor. The output port is electrically connected to the first switch, the second switch, and the third switch. The first switch is electrically connected to a first voltage source and switched on according to a clock signal. The second switch is electrically connected to a second voltage source. The first control unit converts the clock signal to an inverse clock signal, thereby outputting a switch signal for switching on the second switch. The resistor is connected between a third voltage source and the third switch in series. The third switch controls the electric connection between the output port and the third voltage source. The second control unit switches on the third switch according to the inverse clock signal and the switch signal.
