Liquid crystal display and driving method therefor |
摘要 |
A liquid crystal display includes a scanning voltage driver which applies selective scanning voltages to scanning electrodes of a liquid crystal display panel one group of M (an integer of 2 or greater) adjacent scanning electrodes at a time in accordance with M orthogonal function data. A data voltage driver applies to data electrodes of the liquid crystal display panel data voltages selected from M+1 data voltages in accordance with a coincidence number representing a number of coincidences between values of M display data corresponding to the M adjacent scanning electrodes in a current group of scanning electrodes and values of the M orthogonal function data corresponding to the M adjacent scanning electrodes in the current group. The data voltage driver controls a correction period in accordance with a value of a difference between (1) a coincidence number corresponding to the current group of scanning electrodes and (2) a coincidence number corresponding to a previous group of scanning electrodes, and applies to the data electrode during the correction period a corrected data voltage which is equal to a sum of a correction voltage and one of the M+1 data voltages.
