Abstract: A dot matrix display device includes a pixel redraw control unit and a decoder unit. The pixel redraw control unit generates a gate selection signal identifying an address in one direction, a source selection signal identifying an address in another direction intersecting the one direction, and image data which correspond to a pixel electrode part based on a serial signal including an address signal identifying an address of the pixel electrode part and an image signal supplied to the pixel electrode part. The decoder unit supplies a gate signal which activates a gate signal line corresponding to the pixel electrode part based on the gate selection signal, generates a source signal which activates a source signal line corresponding to the pixel electrode part based on the source selection signal, and supplies the image data to the pixel electrode part corresponding to the activated source signal line.

Abstract: An electronic watch includes a liquid crystal driver to drive a liquid crystal panel in which a plurality of pixels are arranged, and a CPU to control the liquid crystal driver. The CPU instructs the liquid crystal driver to output image data to the pixels. The CPU instructs the liquid crystal driver to output AC voltage while reversing the polarity of the AC voltage in predetermined cycles to be applied to display elements included in the respective pixels. When a timing of reversing the polarity is within a period of output of the image data, the CPU delays the timing until after the period.

Abstract: A liquid crystal control circuit is provided for driving a MIP liquid crystal panel. The MIP liquid crystal panel has a plurality of pixels, each of which includes a memory element and a display element. The memory element holds electric potential depending on an image signal. The display element is applied voltage depending on the electric potential which the memory element holds. The liquid crystal control circuit includes an inversion unit that inverts polarity of AC voltage in a first mode in which an enable signal is output. The AC voltage being is applied to the display element in synchronization with outputting of the enable signal. The enable signal activates the image signal output to the MIP liquid crystal panel.
