Patent ID: 7382344

Claim:
A data driving apparatus for a liquid crystal display, comprising: a timing controller configured to make n-number of time divisions of 2n-number of pixel data (wherein n is an integer) to output the 2n-number of pixel data as n-number of time-divided input pixel data; at least one digital-to-analog converter integrated circuit for receiving and converting the n-number of input pixel data into n-number of pixel voltage signals and making k-number of time-divisions of the n-number of pixel voltage signals to output k-number of time-divided pixel voltage signals (wherein k is an integer, and n>k); and at least one output buffer integrated circuit for holding and buffering the k-number of time-divided pixel voltage signals until all of 2n-number of pixel voltage signals have been received and simultaneously outputting the buffered pixel voltage signals to 2n-number of data lines, wherein the digital-to-analog converter integrated circuit is mounted on a tape carrier package connected to a liquid crystal display panel, and the output buffer integrated circuit is mounted on the liquid crystal display panel.
