Abstract:
1. A driving apparatus of a liquid crystal display device, comprising: a shift register array for sequentially generating a sampling signal; a data register for providing pixel data to a latch array through each of transmittance lines; wherein the latch array for sequentially latches the pixel data by designated units in response to the sampling signal to simultaneously output the latched pixel data to a first multiplexer array, the pixel data including even pixel data (RGB even) and odd pixel data (RGB odd); the first multiplexer array for performing time-division on inputted pixel data to supply time-divided pixel data signals, wherein the first multiplexer array performs at least one time-division each horizontal period; a digital-to-analog converter array for converting the time-divided pixel data signals into pixel voltage signals; and a demultiplexer array for driving data lines in a time-division manner to supply the converted pixel voltage signals, wherein the digital-to-analog converter array receives a first time-divided pixel data signal from the multiplexer array and generates a first pixel voltage signal level having a first voltage value corresponding to the first time-divided pixel data signal, generates a second pixel voltage signal level having a voltage at least one-step higher in absolute value than the first pixel voltage signal level and corresponding to the first time-divided pixel data signal, wherein the pixel data include even pixel data (RGB even) and odd pixel data (RGB odd).
