Abstract:
1. An organic light emitting display pixel, the organic light emitting display pixel being driven during a horizontal period having a first period and a second period, the organic light emitting display pixel comprising: an organic light emitting diode; a first driver for developing a reference current flowing into a data line coupled to the organic light emitting display pixel, the reference current charging the data line with a first voltage during the first period; a second driver for developing a pixel current, a sum of the reference current and the pixel current charging the data line with a second voltage during the second period; a first selector coupled between the data line and the first driver and coupled between the data line and the second driver, the first selector being turned-on during the horizontal period for electrically connecting the data line to the first driver and the second driver; and a second selector coupled between the organic light emitting diode and the second driver, the second selector being turned-off during the horizontal period and otherwise being turned-on for electrically connecting the second driver to the organic light emitting diode.
