Semiconductor device

A display control device comprises an output unit that outputs an inverted polarity of an AC signal in a constant cycle, based on a signal of the constant cycle; a stop control unit that stops the reversal of the polarity of the AC signal in the output unit, based on a stop signal; a rewrite control...

More Information
Summary:A display control device comprises an output unit that outputs an inverted polarity of an AC signal in a constant cycle, based on a signal of the constant cycle; a stop control unit that stops the reversal of the polarity of the AC signal in the output unit, based on a stop signal; a rewrite control unit for outputting a display data rewrite signal; and a transmission control unit for controlling the rewrite control unit. The stop signal stops the reversal of the polarity of the AC signal during a period in which the display data rewrite signal is output. The AC signal stopped by the stop signal maintains a polarity before the stop of polarity reversal. The output unit inverts and outputs the polarity of the AC signal, based on the signal of the constant cycle, after a period in which the display data rewrite signal is output.
