ABSTRACT:
A display device including a plurality of data lines for transmitting a data current corresponding to image signals, a plurality of scan lines for selecting select signals, and a plurality of pixel circuits coupled to the data lines and the scan lines. The display device includes a data driver for supplying the data current corresponding to the image signals, and a demultiplexer including first and second sample/hold circuit groups having input terminals coupled to the data driver. Each of the sample/hold circuit groups 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 the data lines, and a scan driver for supplying the select signals to the scan lines.
