ABSTRACT:
A display device including a data driver for supplying data currents corresponding to image signals, and a demultiplexer including first and second sample/hold circuit groups having input terminals coupled to the data driver. Each said sample/hold circuit group includes at least two sample/hold circuits. The display device also includes a switch unit for switching between output terminals of the first and second sample/hold circuit groups and data lines, and a scan driver for supplying select signals to scan lines. 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. Orders in which the data currents are supplied from the data driver are varied.
