Abstract

A light emitting display including data lines for applying data voltages corresponding to video signals, scan lines for transmitting select signals, and pixel circuits. Each pixel circuit includes a light emitting element for emitting light, and a transistor including first to third electrodes, for controlling a current output to the third electrode according to a voltage between the first and second electrodes. Each pixel circuit also includes a first switch for diode-connecting the transistor, a capacitor having a first electrode coupled to the first electrode of the transistor, a second switch for applying a corresponding said data voltage to the second electrode of the capacitor in response to a corresponding said select signal from a corresponding said scan line, and a third switch for substantially electrically decoupling the second electrode of the capacitor from a power supply voltage source.
