LIQUID CRYSTAL DISPLAY DEVICE, ACTIVE MATRIX TYPE LIQUID CRYSTAL DISPLAY DEVICE, AND METHOD OF DRIVING THE SAME
First Claim
1. A method of driving a display device including scanning lines and signal lines comprising:
- during a first frame, applying first image signals to a first group of pixels with a positive polarity and a second group of pixels with a negative polarity; and
during a second frame, applying second image signals to the first group of the pixels with a negative polarity and the second group of the pixels with a positive polarity,wherein the first group of the pixels is adjacent to the second group of the pixels,wherein a frame frequency is at least 100 Hz.

Abstract
A liquid crystal display device with no flicker and with bright excellent display is provided. A polarity pattern of a conventional frame inversion driving is one kind of display. A polarity pattern of a conventional source line inversion driving is two kinds of display, and a disclination pattern is one kind of display. On the contrary, in a circuit structure of the present invention, polarity patterns are made to have not less than four kinds, and disclination patterns are made to have not less than two kinds. By this, bright display in which flicker is not included and poor display due to disclination is improved, can be obtained.
