Liquid crystal display device for displaying display data

A liquid crystal display device for displaying display data comprising:

• a liquid crystal panel including pixel elements arranged in a matrix form;
• a plurality of data drivers for applying graduation voltages corresponding to said display data, to said pixel elements;
• a gate driver for selecting a pixel element to which a graduation voltage is to be applied;
• and
• a liquid crystal control circuit for outputting a transfer clock and said display data to said data drivers, wherein
• said data drivers each comprising a reproducing circuit for reproducing the transfer clock input to the data driver such that the deviations between the duties of said display data and said transfer clock output from said liquid crystal control circuit and the duties of the display data and the transfer clock output from said data driver become small, and for generating a latch clock, and a latch circuit for latching said display data input to said data driver.

A liquid crystal display device for displaying display data comprising:

• a liquid crystal panel including pixel elements arranged in a matrix form;
• a plurality of data drivers cascade-connected with each other for applying graduation voltages corresponding to said display data, to said pixel elements;
• a gate driver for selecting a pixel element to which a graduation voltage is to be applied;
• and
• a liquid crystal control circuit for outputting a transfer clock and said display data to said data drivers, wherein
• said data drivers each comprising a latch circuit for latching said display data so as to increase the margins of setup/hold times of said display data input to the data driver;
• wherein each of said data drivers further comprises a doubling circuit for doubling the transfer clock converted in a converting circuit, and takes in said display data on the basis of the doubled transfer clock.
