Abstract
Drive voltages of a liquid crystal display are adjusted based on one or more environmental conditions. The pixel drive voltages may be adjusted based on temperature. A pixel voltage may be varied such that it is a higher voltage at relatively lower temperatures and a lower voltage at relatively higher temperatures. The window voltage may be varied based on temperature. The window voltage may be stepped through different values within a display phase. The window voltage may be varied during a blanking period of the display phase such that the pixel sees a relatively larger voltage to obtain a desired initial state more quickly. Then, during a light modulating time period, the window voltage may be stepped such that there is a lower voltage field for holding the state of the pixel.
