ABSTRACT:
A pixel and an organic light emitting display using the pixel capable of displaying an image of uniform luminance. A pixel circuit is coupled with at least one scan line and at least one data line. The pixel circuit first charges a voltage corresponding to a first data signal across at least one capacitor when the first data signal is supplied from the data lines, and second charges the at least one capacitor when a current as a second data signal is provided. The pixel circuit controls an amount of current supplied to a second power supply from the first power supply through the organic light emitting diode according to the voltage charged in the at least one capacitor. Accordingly, an image of uniform luminescence may be displayed.
