Title:
METHOD OF DRIVING LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
Japanese Patent JPH10282937
Kind Code:
A
Abstract:

To prevent flickering from being generated even when a liquid crystal display device displays a fixed pattern like a checker.

In this active matrix type of a liquid crystal display device, TFT 6 connected with pixel electrodes 7-22 are formed in the neighborhood of intersectional parts of gate bus lines 4 and data bus lines 5 which are formed on a substrate in a matrix form, and liquid crystal is held between the pixel electrodes and counter electrodes, and transmittance of the liquid crystal is controlled according to the voltage applied to the pixel electrodes 7-22. A gate bus line 4 is selected so that an interlace drive is performed on a screen, and there are limited up to such two successive pixels as the voltage applied on the horizontally adjacent pixel electrodes 7, 8 always has an opposite polarity to a counter electrode voltage and the voltage applied on the vertically adjacent pixel electrodes 7, 15 has a same polarity as the counter electrode voltage.
