Patent ID: 8199079

Claim:
A light emitting display comprising: a scan driver for supplying scan signals to scan lines in sequence; a data driver provided with a plurality of output lines and for supplying a plurality of data signals to the respective output lines while the scan signals are supplied; an image displaying part comprising a plurality of pixels in regions crossed by the scan lines and a plurality of data lines; a plurality of demultiplexers, each of the demultiplexers coupling a respective one of the output lines and comprising a plurality of data transistors adapted to supply a respective one of the data signals from the respective one of the output lines to more than one of the plurality of data lines; and a plurality of initializers respectively coupled to the plurality of data lines, each of the initializers comprising a plurality of initialization transistors each adapted to apply a predetermined voltage to a corresponding one of the plurality of data lines, wherein the plurality of initialization transistor have different channel widths in accordance with emission efficiencies of the pixels, and wherein an initialization transistor among the plurality of initialization transistors configured to have a shortest turned-on period has a channel width greater than that of another initialization transistor among the plurality of initialization transistors configured to have a longest turned-on period.
