Patent ID: 7365742

Claim:
A light emitting display including a plurality of data lines for applying data voltages corresponding to video signals, a plurality of scan lines for transmitting select signals, and a plurality of pixel circuits coupled to the scan lines and the data lines, each said pixel circuit comprising: a light emitting element for emitting a light beam corresponding to a current, which is applied thereto; a transistor including a first electrode, a second electrode coupled to a power supply voltage source, and a third electrode coupled to the light emitting element, for controlling the current output to the third electrode according to a voltage applied between the first and second electrodes; a first switch for diode-connecting the transistor in response to a first control signal; 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 coupled between the second electrode of the capacitor and the power supply voltage source, for substantially electrically decoupling the second electrode of the capacitor from the power supply voltage source in response to a second control signal.
