Patent ID: 7187351

Claim:
A light emitting display comprising: 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 first switch for diode-connecting the first transistor in response to a first control signal; a second switch for transmitting a data signal from the data line in response to the select signal from the scan line; a first storage element for storing a first voltage corresponding to the data current from the second switch in response to a second control signal; a second storage element for storing a second voltage corresponding to a threshold voltage of the first transistor in response to a disable level of the second control signal; and a third switch for transmitting the driving current from the first transistor to the light emitting element in response to a third control signal, wherein the second voltage is applied to the second storage element after the first voltage is applied to the first storage element, and a third voltage stored in the first storage element is applied to the first transistor by coupling of the first and second storage elements to output the driving current.
