A liquid crystal display apparatus including a display control unit which includes a reordering unit which reorders originally ordered display data inputted thereto, and sends the reordered display data to M ones of a plurality of drivers through a bus line to which the M drivers are connected, where M is a positive integer, the M drivers connected to the bus line being divided into N driver groups, where N is a positive integer smaller than M, and a clock generating unit which generates N clock signals having a same frequency as and different phases from each other, and sends the N clock signals to the N driver groups respectively such that each one of the N clock signals is sent to a respective one of the N driver groups.

Liquid crystal display apparatus having display control unit for lowering clock frequency at which pixel drivers are driven

A liquid crystal display apparatus comprises a liquid crystal display panel having a plurality of pixels formed in a matrix configuration, M driving means for applying a plurality of pixels arranged in a column direction with video voltage based on display data, where M is a positive integer, and display control means for sending inputted display data to the M driving means, and for generating control signals including at least clock signals based on input display control signals inputted thereto and sending the control signals to the M driving means to control and drive the M driving means, wherein the display control means reorders originally ordered display data inputted thereto and sends the recorded display data to the M driving means, and generates N clock signals having the same frequency as and different phases from each other, where N is a positive integer smaller than M, and sends the N clock signals to N driving means groups, respectively.
