ABSTRACT:
A drive apparatus has a ferroelectric LCD for displaying information, a thermo detector for detecting the temperature of the LCD, a driver for driving the LCD by a drive signal having a pulse width corresponding to an output from the thermo detector, and a computer for controlling the driver. When a plurality of display elements are to be driven, they can be divided into blocks and controlled in accordance with an average temperature of each block.
