Abstract:
A data-driving a liquid crystal display includes a first multiplexer array for alternately changing a supplying sequence of time-divided pixel data and time-divided pixel data, a second multiplexer array for alternately outputting the time-divided pixel data with an unshifted output channel of the time-divided pixel data and outputting the time-divided pixel data shifted to the right side by one channel in response to a control signal, a digital-to-analog converter array converting the time-divided pixel data into analog pixel signals having a polarity opposite to the pixel data of adjacent channels, a third multiplexer array for alternately outputting the pixel signals with an unshifted output channel of the pixel signals and outputting the pixel signals shifted to the left side by one channel in response to the control signal, and a demultiplexer array for alternately changing a supplying sequence of the time-divided pixel signals for each horizontal period and each frame.
Abstract:
An apparatus and method for data-driving a liquid crystal display device is disclosed in the present invention. The apparatus includes a first multiplexer array performing a time-division on inputted pixel data into odd-numbered and even-numbered pixel data, alternately changing a supplying sequence of the time-divided pixel data for each horizontal period and each frame, and supplying the time-divided pixel data, a second multiplexer array alternately maintaining an output channel of the time-divided pixel data and outputting the time-divided pixel data shifted to the right side by one channel for each horizontal period, a digital-to-analog converter array converting the time-divided pixel data into analog pixel signals having a polarity opposite to the pixel data of adjacent channels, a third multiplexer array alternately maintaining the output channel of the pixel signals and outputting the pixel signals shifted to the left side by one channel for each horizontal period, and a demultiplexer array performing a time-division on data lines into odd-numbered and even-numbered data lines and supplying the pixel signals to the time-divided data lines, and alternately changing a supplying sequence of the pixel signals for at least one horizontal period and one frame.
