Abstract

A pixel driver includes an input unit, a power-switching unit, a voltage-dividing unit, a pixel-driving unit and a shorting unit. The input unit outputs a data voltage according to a first scan signal and a data signal. The power-switching unit outputs a first power voltage according to a first power voltage and a power-controlling signal. The voltage-dividing unit adjusts a control voltage according to a second scan signal. The pixel-driving unit includes a control terminal, a first terminal and a second terminal. The pixel-driving unit provides a driving current to an LED according to the voltage difference between the control terminal and the second terminal. The shorting unit connects the control terminal to the first terminal according to the first scan signal.
