Patent ID: 8872742

Claim:
A data drive circuit of a liquid crystal display device, comprising: a controller that differently realigns an RGB data pattern of digital RGB data, which are in series input thereto, by a unit of one horizontal line for each k horizontal period, wherein the k horizontal period is an amount of time it takes to scan k horizontal lines; a latch part that latches the digital RGB data of the pattern realigned by the controller; first to m th (m≧2) A/D converters that convert the digital RGB data, which are latched in accord with the RGB data pattern realigned by the controller, into analog data voltages; first to m th (m≧2) output buffers that buffer the analog data voltages which are converted in accord with the RGB data pattern realigned by the controller; an output controller that controls the analog data voltages, which are buffered in accord with the RGB data pattern realigned by the controller, to be outputted in accord with an arrangement pattern of sub-pixels which constitute each pixel; and first to m th (m≧2) switches that supply the analog data voltages, which are buffered in accord with the RGB data pattern realigned by the controller, to each pixel by making the analog data voltages in accord with the arrangement pattern of the sub-pixels which constitute each pixel, under the control of the output controller.
