Patent ID: 7129643

Claim:
A light-emitting display comprising a plurality of data lines for transmitting data currents, a plurality of first scan lines for transmitting select signals, a plurality of second scan lines for transmitting first control signals, and a plurality of pixel circuits respectively formed at a plurality of pixel areas defined by the data lines and the first scan lines, and coupled to the data lines, the first scan lines and the second scan lines, each said pixel circuit comprising: a light-emitting element for emitting light based on a driving current, which is applied thereto; a first switching element for transmitting a corresponding said data current from a corresponding said data line in response to a corresponding said select signal from a corresponding said first scan line; a first transistor for supplying the driving current applied to the light emitting element to emit light, and being diode-connected irrespective of a level of a corresponding said first control signal while the corresponding said data current is transmitted from the corresponding said data line; a first storage element for storing a first voltage corresponding to the corresponding said data current from the corresponding said data line; and a second storage element coupled between the first storage element and a corresponding said second scan line, for converting the first voltage of the first storage element into a second voltage through coupling to the first storage element when the corresponding said first control signal is switched from a first level to a second level, wherein the first transistor supplies the driving current corresponding to the second voltage, and the light-emitting element emits light with a brightness corresponding to the driving current.
