Abstract
A display such as a ferroelectric liquid crystal display includes a matrix of pixels, for instance formed at the intersections of data electrodes and strobe electrodes. In order to address an intermediate grey level, each pixel is switched from the normally black mode to the grey level in odd frames and from the normally white mode to the grey level in even frames. Variations in the grey levels, for instance caused by temperature variations, act in opposite directions so that the average grey level over time of the pixel varies relatively little.
