Patent ID: 8040309

Claim:
A display panel with an image sticking elimination circuit comprising a plurality of pixel units driven by a gate driving circuit and a data driving circuit, said gate driving circuit being driven by a first voltage and a second voltage, said first voltage turning on said pixel units for receiving signals from said data driving circuit, said second voltage turning off said pixel units for preventing said pixel units from receiving signals from said data driving circuit, said image sticking elimination circuit comprising: a charge storage device, having a first terminal and a second terminal, said second terminal of said charge storage device being coupled to ground; an isolation device, having a first terminal, a second terminal and a third terminal, said first terminal of said isolation device being coupled to said first terminal of said charge storage device, said second terminal of said isolation device being coupled to said first voltage, said third terminal of said isolation device being coupled to said second voltage, said isolation device being turned on when an abnormal power shut down occurs and not applying said first voltage to said second terminal of said isolation device; a diode having a first terminal and a second terminal, said first terminal of said diode being coupled to said first voltage, said second terminal of said diode being coupled to said first terminal of said charge storage device, wherein said second terminal of said isolation device is coupled to a connection between said first voltage and said first terminal of said diode, wherein said second terminal of said isolation device is electrically coupled directly to said first voltage and said first terminal of said diode without an intervening switch; and a switch, coupled between a data line driven by said data driving circuit and an Electrostatic Discharge circuit (ESD circuit), said switch determines whether or not to turn itself on according to voltage of said third terminal of said isolation device, and said switch is turned on when said abnormal power shut down occurs and said ESD circuit discharges said data line to ground.
