Display devices and display elements thereof
First Claim
1. A display device comprising a plurality of pixels arranged to from a matrix covering an area, and control means for individually setting the properties of each pixel whereby desired information can be displayed over said area, characterised by light reflective pixels which each comprise a plurality of sets of two or more vanes arranged one behind the other with a forward surface of each set visible from the front, the vanes within each set lying in closely adjacent parallel planes, the sets being also parallel but displaced in parallels planes;
- driving means for conjointly driving a selected group of corresponding vanes in each set, except the foremost, so that the vane forward surfaces are selectively viewable from the front;
the vanes in at least one group being colored with a respective plain color which is different from that of the vanes in at least one other group.

Abstract
A display device comprising a plurality of pixels arranged in a matrix to form a total image display area. Each pixel is comprised of a plurality of sets of two or more vanes with the vanes of each set lying in closely adjacent parallel planes. Driving means is provided for conjointly driving a selected group of corresponding vanes in each set so that the vane forward surfaces are selectively viewable from the front. The vanes in at least one group are colored with a plain color which differs from the color of the vanes in at least one other group.

13. A light reflective display element having a plurality of sets of two or more vanes arranged one behind the other with a forward surface of each set visible from the front, the vanes within each set lying in closely adjacent parallel planes, the sets being also parallel but displaced one behind the other;
- all those groups formed by corresponding vanes in each set except the foremost being individually drivable so that the forward surfaces of those vanes are selectively viewable from the front;
each group of vanes being coloured with a respective plain colour different from that of the other group(s); and
driving means capable of positioning the vanes of each drivable group in two extreme positions and also in one or more discrete spaced intermediate position(s). - View Dependent Claims (14, 15, 17, 18)

16. A light reflective display element having a plurality of sets of two or more vanes arranged one behind the other with a forward surface of each set visible from the front, the vanes within each set lying in closely adjacent parallel planes, the sets being also parallel but displaced one behind the other;
- all those groups formed by corresponding vanes in each set except the foremost being individually drivable so that their forward surfaces are selectively viewable from the front each group of vanes being coloured with respective plain colour different from that of the other group(s).
