ABSTRACT:
Based on temperature data from temperature detection means, the temperature of a liquid crystal device is judged to be present in which of prescribed plural temperature regions. Based on the judgment, in each temperature region, a drive voltage generation means is controlled to generate a constant drive voltage which is different from that in another region, and a drive signal generation means is controlled to generate a drive signal having a pulse width which varies depending on the temperature of the liquid crystal device. A liquid crystal disposed between a pair of substrates of the liquid crystal device is driven by application of the constant drive voltage for the pulse width of the drive signal. The drive system allows a sufficient temperature compensation by a relatively simple apparatus organization.
