ABSTRACT:
A light emitting display including data lines for transmitting data voltages, scan lines for selecting select signals, and pixel circuits. The pixel circuit is coupled to a data line and a scan line. The pixel circuit includes a transistor including first, second, and third electrodes, wherein the third electrode outputs a current corresponding to a voltage between the first and second electrodes. A light emitting element coupled to the third electrode emits light corresponding to the current outputted by the third electrode. A first switch transmits a data voltage in response to a select signal from the scan line. A voltage compensator receives the data voltage transmitted by the first switch and a second power supply voltage and applies a compensated data voltage based on the data voltage, a first power supply voltage and the second power supply voltage to the first electrode of the transistor.
