Abstract: The present invention discloses a data transmission apparatus and method to lower a data transmission voltage for eliminating EMI. In the data driving apparatus, a timing controller aligns input pixel data, lowers input data voltages of the input pixel data, and outputs to a plurality of data transmission lines. A data driver raises the lowered input data voltages for driving the liquid crystal display panel and then converts into analog pixel voltage signals to supply the analog pixel voltage signals to the data lines.

Abstract: A data driving apparatus and method for a liquid crystal display wherein a digital to analog converter part is driven on a time-division basis to increase the number of output channels of a data driving IC without excessively increasing a chip area or by reducing a chip area in comparison to the existing chip area, thereby reducing the number of data driving IC's and TCP's. In the apparatus, a multiplexor part performs a time-division of input pixel data to output the time-divided pixel data. A digital to analog converter part converts the pixel data from the multiplexor part into pixel voltage signals. A demultiplexor part selectively supplies the pixel voltage signals from the digital to analog converter part to a plurality of output lines of the demultiplexor part. A sampler and holder part samples and holds the pixel voltage signals from the demultiplexor part to output the sampled and held pixel voltage signals to a plurality of data lines of the liquid crystal display.
