Claim Text:
1. A pixel circuit, comprising: a first switch, a control end of said first switch is coupled to a scan line; a second switch, a second end of said second switch is coupled to a first end of said first switch, a first end of said second switch is coupled to a first source, a control end of said second switch is coupled to a data line; a third switch, a second end of said third switch is coupled to a second source; an energy storage device, a first end of the energy storage device is coupled to a first end of said third switch; and a resistor, said resistor is coupled to a second end of said first switch and said first end of said third switch; wherein, controlling said third switch, said first end of said energy storage device is charged to a voltage of said second source, said first switch and said second switch are controlled to switch on, so that said first end of said energy storage device discharging to said first source, said second switch switches off when said first end of said energy storage device reaches a desired pixel voltage.
