Patent ID: 7468718

Claim:
A display device including a plurality of data lines, a plurality of scan lines for transmitting select signals, and a plurality of pixel circuits coupled to the data lines and the scan lines, comprising: a data driver for supplying data currents corresponding to image signals; a demultiplexer including first and second sample/hold circuit groups having input terminals coupled to the data driver, each said sample/hold circuit group including at least two sample/hold circuits; a switch unit for switching between output terminals of the first and second sample/hold circuit groups and the data lines; and a scan driver for supplying the select signals to the scan lines, wherein one of the sample/hold circuits of the first sample/hold circuit group samples a corresponding one of the data currents during at least a part of a period in which another one of the sample/hold circuits of the first sample/hold circuit group outputs a current to the switch unit, wherein one of the sample/hold circuits of the second sample/hold circuit group samples a corresponding one of the data currents during at least a part of a period in which another one of the sample/hold circuits of the second sample/hold circuit group outputs a current to the switch unit, wherein orders in which the data currents are supplied from the data driver are varied, and wherein the switch unit programs the output currents of the first and second sample/hold circuit groups, respectively, to first and second data lines from among the data lines in one frame, and programs the output currents of the first and second sample/hold circuit groups, respectively, to the second and first data lines from among the data lines in another frame.
