LIQUID CRYSTAL DISPLAY DEVICE AND ITS DRIVING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a driving method of a liquid crystal display device, by which electromagnetic wave noise radiated from the device itself can be reduced than heretofore. SOLUTION: The liquid crystal display device has a liquid crystal display panel having a plurality of pixels, a driving means which outputs gradation voltages corresponding to display data being inputted, a display control means which supplies the display data being inputted from the external to the driving means and bus lines through which the display data being supplied from the display control means are inputted to the driving means. When the data values of the all display data are '1' in the display control means, the data values of specific display data among the display data are reversed so that the voltage on one of the lines becomes a first level and the voltage on the other line becomes a second level in the mutually adjacent lines of the bus lines and the values are supplied to the driving means.
