Abstract:
A display for displaying an image, said display comprising:a first substrate having thereon a plurality of row electrode means,a second substrate having thereon a plurality of column electrode means,a layer of electro-optic material disposed between said first and said second substrate thereby to define a pixel between each crossing of a row electrode means with a column electrode means,row drive means associated with said first substrate for applying a respective selected voltage profile across each row electrode means in a direction transverse to the thickness of said layer,column drive means associated with said second substrate for applying a respective selected voltage profile across each column electrode means in a direction transverse to the thickness of said layer,whereby the electrical field in each pixel in the direction transverse to the thickness of the electro-optic layer may be selected to provide a non-uniform optical output across said pixel, andmeans for controlling voltage profiles applied by said row drive means and said column drive means to provide selected pixels with a predetermined non-uniform pixel output in which the boundary between the ON and OFF regions within the pixel is selected for spatial correspondence with the corresponding region of the image to be displayed.
