Electronic discharging control circuit and method thereof for lcd

A method of discharging pixel transistors of an LCD device, comprising:

• detecting whether the LCD device stops displaying an image;
• providing a first signal to disable a power module of the LCD device and turn off a pixel transistor turn-on potential level after a first delay time;
• and
• providing a second signal to turn on all the pixel transistors after a second delay time.

An Applied Specific Integrated Circuit (ASIC), for a capacitor charging/discharging device, having a plurality of capacitors, comprising:

• a host control unit;
• a signal detecting unit, receiving a first disable signal outputted from the host control unit and outputting a second disable signal to a power supply module outside of the ASIC, for disabling a part of the power supply module simultaneously, and disabling other part of the power supply module which controls the capacitors after a first delay time;
• and
• a delay unit, receiving a second signal from the signal detecting unit, and outputting to the capacitor charging/discharging device after having paused for a second delay time, such that a plurality of switches controlling the capacitors are turned on.
