Liquid crystal control circuit, electronic timepiece, and liquid crystal control method

A liquid crystal control circuit for driving a liquid crystal panel, wherein

• the liquid crystal panel has a plurality of pixels, each of which including a memory element and a display element,
• the memory element is configured to hold electric potential depending on an image signal,
• the display element is configured to be applied voltage depending on the electric potential which the memory element holds, and
• the liquid crystal control circuit comprises:
• a counter configured to output an inversion request signal for requesting inversion of polarity of AC voltage applied to the display element, at a predetermined interval;
• a polarity inversion unit configured to invert the polarity of the AC voltage in response to the inversion request signal;
• an enable signal output unit configured to output an enable signal to activate the image signal which is output to the liquid crystal panel;
• and
• an exclusive output controller configured to determine whether to output the inversion request signal to the polarity inversion unit or to output the output request signal to the enable signal output unit.

• the liquid crystal panel has a plurality of pixels, each of which including a memory element and a display element,
• the memory element is configured to hold electric potential depending on an image signal and is configured to change the held electric potential based on activation of an enable signal,
• the display element is configured to be applied voltage depending on the electric potential which the memory element holds, and
• the liquid crystal control method comprises:
• holding off outputting the enable signal, for a predetermined first period before polarity of AC voltage applied to the display element is inverted and a predetermined second period after the polarity of the AC voltage is inverted;
• and
• holding off inversion of the polarity of the AC voltage, for an output period of the enable signal and the predetermined first period after the output period.
