Patent ID: 7164401

Claim:
A light emitting display comprising: a display panel on which are formed a plurality of data lines for transmitting data current that displays video signals, a plurality of scan lines for transmitting a select signal, and a plurality of pixel circuits formed at a plurality of pixels defined by the data lines and the scan lines, wherein at least one pixel circuit includes: a light emitting element for emitting light corresponding to an applied current; a first transistor, having a first main electrode, a second main electrode and a control electrode, for supplying a driving current for the light emitting element; a second transistor being diode-connected; a first switch for transmitting a data current from the data line to the second transistor in response to a select signal from the scan line; a first storage element having a first end coupled to the first main electrode of the first transistor and a first main electrode of the second transistor, and a second end thereof coupled to the control electrode of the first transistor, the second end being coupled to a gate of the second transistor in response to a first level of a first control signal; a second storage element coupled between the second end of the first storage element and a control electrode of the second transistor in response to a second level of the first control signal; and a second switch for coupling the first transistor and the light emitting element in response to a second control signal.
