A matrix display system, comprising a display panel (10) having a row and column array of light modulating picture elements (12), for example liquid crystal picture elements, and panel illuminating means (19), is operated by driving the rows of picture elements such that the display information of successive fields of an applied video signal is written into the panel in respective panel display information address periods that are substantially less than the applied video signal field period and separated by a time interval, and such that successive periods in which display fields are presented to a viewer are separated by intervals in which substantially no display output is produced. The resulting dark intervals lead to an improvement in perceived resolution of moving images. The illumination means can be controlled so as to produce a display output during at least a part of the interval and substantially no display output during at least a part of the address period. Alternatively, the picture elements can be driven to their substantially non-transmissive display states during the interval between successive display information address periods and the illumination means may be turned off for a part of that interval. |
