<p>In a matrix liquid crystal display, the visual contrast of the individual image points (= pixels) is enhanced by illuminating or exposing to illumination the pixel lines (2) successively in groups at least during part of the time in which they show maximum contrast. Addressing of the illumination is adapted to the duration and phase of addressing of the individual pixel lines. Strip-wise illumination of the pixel lines can be effected, for example, by using strip-shaped light sources (4) or a second liquid crystal system which can either have a strip structure or be composed of strips and acts like a stepwise moving slot.</p> |
