Patent ID: 8159438

Claim:
A liquid crystal display device comprising: a signal writing means for writing display signals to data lines in a display area comprising a matrix of pixels; and a pre-charging means for writing a gray-scale level to the data lines before the signal writing means writes the display signals to the data lines, the gray scale level serving as a pre-charge signal level; wherein the pre-charge signal is selectively applied to each of the data lines simultaneously and the pre-charge signal is also directly applied to another portion of each pixel as VCOM and wherein the pre-charge signal is altered during each selective application of the pre-charge signal such that the pre-charge signal value that is achieved during the selective application of the pre-charge signal to the data lines is an opposite polarity of a prior value and the pre-charge signal is disconnected from the data lines while the data signals are sequentially applied to the data lines; and further wherein the pre-charge signal is selectively inhibited during 1F driving reverse mode and/or a non-display period in a partial mode.
