Pixel circuit for active matrix display apparatus and the driving method thereof
Provided is the pixel circuit for active matrix display apparatus and the driving method thereof, which is controlled by digital signal. The pre-charge pixel voltage is controlled and discharged by controlling the resistor and transistors, so that the desired grey scale is generated. The pixel circuit includes: a first switch, a second switch, a third switch, an energy storage device and resistor. By controlling the third switch, the first end of the energy storage device is charged to the voltage of the second source. The first switch and the second switch are controlled to switch on, so that the first end of the energy storage device discharging to the first source. The second switch switches off when the first end of the energy storage device reaches the desired pixel voltage.
