Patent ID: 7003210

Claim:
A display device ( 1 ) for displaying image information ( 4 ) comprising: a display panel ( 2 ) comprising an optical waveguide plate ( 22 ), a second plate ( 24 ) facing the optical waveguide plate ( 22 ), a movable element ( 21 ) between the optical waveguide plate ( 22 ) and the second plate ( 24 ), and picture elements ( 5 ) for decoupling light from the optical waveguide plate ( 22 ) through local contact of the movable element ( 21 ) with the optical waveguide plate ( 22 ), said picture elements ( 5 ) being arranged in a predetermined first number of substantially parallel lines ( 6 ); and selection means ( 3 ) arranged for multiline addressing of the picture elements ( 5 ) arranged in a predetermined second number of lines ( 6 ), forming part of the predetermined first number of substantially parallel lines ( 6 ), and comprising processing means ( 11 , 12 ) arranged for: decomposing the image information ( 4 ) into a number of subfields ( 13 ) to be displayed, each subfield ( 13 ) having its own predetermined number of active standard periods of time ( 19 ) per line ( 16 ); and executing a subfield modulation scheme by generating a sequence ( 14 ) of activating, active, and deactivating standard periods of time, said sequence ( 14 ) comprising: in a first subfield ( 13 ), an activating and a deactivating standard period of time ( 17 , 18 ) to activate and to deactivate picture elements ( 5 ) arranged in a last line ( 16 ) of the predetermined second number of lines; and in a second consecutive subfield ( 13 ), an activating and a deactivating standard period of time ( 17 , 18 ) to activate and to deactivate picture elements ( 5 ) arranged in a first line ( 16 ) of the predetermined second number of lines, characterized in that the activating standard period of time ( 17 ) for activating the picture elements ( 5 ) arranged in the first line ( 16 ) in the second consecutive subfield ( 13 ) is substantially a next consecutive standard period of time after the activating standard period of time ( 17 ) for activating the picture elements ( 5 ) arranged in the last line ( 16 ) of the first subfield ( 13 ), under predetermined conditions of the predetermined number of active standard periods of time and the predetermined second number of lines.
