Abstract
Official abstract text for this publication.
An embodiment of the present invention switches, in a display driving circuit of a liquid crystal display device which carries out CC driving, between a two-line reversal driving mode in which a polarity of a data signal supplied to a source line is reversed every two horizontal scanning periods and a one-line reversal driving mode in which a polarity of a data signal supplied to a source line is reversed every one horizontal scanning period. In at least one example embodiment, a polarity signal reverses its polarity every two horizontal scanning periods in the two-line reversal driving mode, and reverses its polarity every one horizontal scanning period in the one-line reversal driving mode.
First claim
Opening claim text (preview).
The invention claimed is: 1. A display driving circuit for use in a display device in which by supplying a retention capacitor wire signal to a retention capacitor wire forming a capacitor with a pixel electrode included in a pixel, a signal potential written into the pixel electrode from a data signal line is changed according to a change in potential of the retention capacitor wire signal, the signal potential written into the pixel electrode is one of decreased if the polarity o…
