Abstract
A data driver includes a multi-channel sample/hold circuit electrically connected between a digital-to-analog converter and a data buffer. The multi-channel sample/hold circuit includes a first sample/hold circuit connected to a first channel and a second sample/hold circuit connected to a second channel. The first sample/hold circuit performs a first drive operation and a second drive operation. The first drive operation includes sampling a data voltage as a buffer input voltage and maintaining the buffer input voltage during an nhorizontal time. The second drive operation includes outputting the buffer input voltage to an output terminal of the buffer during an (n+1)horizontal time. The second sample/hold circuit performs the second drive operation during the nhorizontal time and performs the first drive operation during the (n+1)horizontal time.
