Patent ID: 7605810

Claim:
A display device including a plurality of data lines comprising a first data line and a second data line, a plurality of scan lines for transmitting select signals, and a plurality of pixel circuits coupled to the data lines and the scan lines, the display device 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, and wherein the switch unit is configured to program the current output by the first sample/hold circuit group to the first data line and the current output by the second sample/hold circuit group to the second data line in one frame, and to program the current output by the first sample/hold circuit group to the second data line and the current output by the second sample/hold circuit group to the first data line in another frame.
