Patent attributes
A method of driving a liquid crystal display, having a liquid crystal interposed between an upper substrate and a lower substrate, capable of implementing a full color display with a low driving frequency and without increasing the number of bits of driving data by using an analog and digital mixed driving technique the method includes driving the liquid crystal in accordance with driving data of predetermined bits corresponding to each gradation, wherein a pulse corresponding to each bit of the driving data has a predetermined pulse width and a predetermined voltage level, and at least one of the pulse widths and the voltage levels of a pulse corresponding to each bit of the driving data is varied to drive the liquid crystal so that the gradation is displayed. The pulse corresponding to at least one bit of the driving data of predetermined bits is made to have at least one of its width and voltage level varied in accordance with the gradation, or is made to have its voltage level constant and its width varied, to have its pulse width constant and its voltage level varied, or is made to have its pulse width and voltage level varied at the same time.
