Abstract: A display device includes at least one data line, at least one scan line, and at least one pixel circuit. The pixel circuit is coupled to a corresponding data line and a corresponding scan line. The pixel circuit includes a light emitting diode (LED), a voltage to time converter, a selection circuit, and a current driver. The current driver is coupled to the LED for controlling the LED. The selection circuit transmits the data voltage of a data line to the voltage to time converter during the scan operation. The voltage to time converter includes an input terminal for receiving the data voltage, and an output terminal for turning on the LED to generate a predetermined driving current for a period of time. When the absolute value of the data voltage is greater, the period of time is longer.
