Method for driving display device

A method for driving a display apparatus, wherein the display apparatus comprises an OLED, a driver transistor and first to fourth switch transistors, the method comprising:

• connecting a source of the first switch transistor to a data signal power supply, connecting a drain of the first switch transistor to a drain of the driver transistor and connecting a gate of the first switch transistor to a second scan power supply;
• connecting a source of the second switch transistor to the drain of the driver transistor, connecting a drain of the second switch transistor to a positive power supply and connecting a gate of the second switch transistor to an emission power supply;
• connecting a source of the third switch transistor to a reference power supply, connecting a drain of the third switch transistor to a gate of the driver transistor and connecting a gate of the third switch transistor to a first scan power supply;
• connecting a source of the fourth switch transistor to a gate of the driver transistor, connecting a drain of the fourth switch transistor to a source of the fifth switch transistor and connecting a gate of the fourth switch transistor to the second scan power supply;
• connecting a cathode of the OLED to a negative power supply;
• and
• conducting a voltage difference between the positive power supply and the negative power supply in a range from 7.1 V to 9.6 V.
