Abstract:
A pixel includes an organic light emitting diode (OLED) having a cathode electrode coupled to a second power supply, a pixel circuit configured to control an amount of current supplied to the OLED to correspond to a previous data signal, and a driver configured to store a present data signal supplied from a data line and to supply the previous data signal to the pixel circuit. The OLED, pixel circuit, and driver may be controlled by signals in a frame that includes first through fourth periods, the second power supply may be set to a first voltage in the first and second periods and to a second voltage in the third and fourth periods, and the first voltage may be a voltage at which the OLED does not emit light and the second voltage may be a voltage at which the OLED emits light.
