Abstract
A driver circuit of a display device is provided. The driver circuit includes a high-side transistor, a high-side voltage drop suppressor circuit, a low-side transistor, a low-side voltage drop suppressor circuit and a control circuit. When the driver circuit supplies power supplies power generated from a high-side input voltage, the control circuit turns on the high-side voltage drop suppressor circuit for reducing a voltage drop across a first terminal and a second terminal of the high-side transistor. When the driver circuit supplies power generated from a low-side input voltage, the control circuit turns on the low-side voltage drop suppressor circuit for reducing a voltage drop across a first terminal and a second terminal of the low-side transistor.
