LIQUID CRYSTAL DISPLAY DEVICE AND DRIVING METHOD THEREFOR

摘要

There is provided a liquid crystal display device which is capable of reducing power consumption while preventing liquid crystal deterioration.;The liquid crystal display device performs an intermission driving. The liquid crystal display device includes a polarity indication section, which controls a driving section included in the liquid crystal display device so that the data voltages to be written to the pixel formation portions in a first refreshing frame included in the drive period have a same polarity as of the data voltages written to the pixel formation portions in the refreshing frame immediately preceding the first refreshing frame and that the data voltage polarity is inverted for each refreshing frame during the drive period, if the drive period includes an even number of the refreshing frames.

主权项

1. A liquid crystal display device comprising a plurality of pixel formation portions and performing an intermission driving of alternately repeating a drive period for writing data voltages based on an externally supplied image signal to the pixel formation portions and an intermission period for stopping writing of the data voltages to the pixel formation portions, the device further comprising:
a driving section configured to write the data voltages to the pixel formation portions, and a display controller configured to control the driving section, the display controller including: a frame setting section configured to control the driving section so that the drive period includes one or more refreshing frames, which are frames for writing the data voltages to the pixel formation portions, and the intermission period includes at least one non-refreshing frame, which is a frame for stopping writing of the data voltages; and a polarity indication section configured to control the driving section so that the data voltages to be written to the pixel formation portions in a first refreshing frame included in the drive period have a same polarity as of the data voltages written to the pixel formation portions in a refreshing frame immediately preceding the first refreshing frame and that the data voltage polarity is inverted for each refreshing frame during the drive period, if the drive period includes an even number of the refreshing frames.
