摘要：To compensate for the variation of the transmission-voltage characteristic curve due to temperature changes in a ferro-electric display device, the display device is provided with one or more measuring elements (5) for measuring the polarization current. The drive voltages are corrected by means of the polarization current which is used as a feedback parameter.
