ABSTRACT:
A display apparatus which is not adversely affected by a change in the drive waveform or environmental conditions. The display apparatus include a display device, a temperature detection device for detecting the temperature of the display device, and control means that controls the drive conditions for display device. The control means switches a driving waveform based on data from the temperature detection device. The effective value of a selection pulse is preferable changed simultaneously with the waveform switching. The waveform switching may be performed in during a temperature rise rather then during a temperature fall, and may be forbidden for a prescribed period after a waveform switching. The waveform switching may be also be performed between two types of waveforms including or not including a pause period.
