Active matrix type device using forcible rewriting |
摘要 |
Power consumption is reduced by decreasing the frequency of image rewriting to pixels in displaying images which have a portion of a screen that does not vary between frames. On the other hand, to cope with the phenomenon that image information (for instance, pixel voltages) deteriorates over time, a refresh operation is performed regularly. Interlaced scanning is performed skipping a plurality of rows. The refresh operation is performed over several frames in which part of the rows are refreshed in one frame. A flicker is thus prevented which occurs when the entire screen is refreshed in one frame.
