ABSTRACT:
A display panel includes a matrix of pixels each constituted by a pair of oppositely disposed electrodes and a liquid crystal disposed between the electrodes. A current signal, particularly one associated with inversion of spontaneous polarization of the liquid crystal is detected at plural pixels. The display panel is driven by applying drive signals thereto while correcting the drive signals based on the detected current signal. As a result, a threshold distribution typically attributable to a temperature distribution on the display panel is accurately compensated for. The display system thus constituted is particularly useful for gradational display.
