Abstract
A display presenting a three-dimensional visual effect, has (I) a plurality of stacked layers of a display material containing a plurality of pixels which are each independently switchable from a first visual state to a second visual state, each layer having pixels of the same color or combination of colors; (II) switching means for independently switching each pixel from the first visual state to the second visual state; and (III) separating means for providing a separation between adjacent layers of display material. If the number of layers of display material is less than four, the separation between adjacent layers is at least 0.5 mm. Preferably, the display material is encapsulated liquid crystal material.
Claims8
A display presenting a three-dimensional visual effect, comprising (I) a plurality of stacked layers of a display material comprising encapsulated liquid crystal material and containing a plurality of pixels which are each independently switchable from a first visual state to a second visual state, each layer having pixels of the same color or combination of colors:
- (II) switching means for independently switching each pixel from the first visual state to the second visual state;
- (III) separating means for providing a separation between adjacent layers of display material;
- provided that where the number of layers of display material is less than four, the separation between adjacent layers is at least 0.5 mm and (IV) filler material which fills the separation between adjacent layers and has a refractive index substantially equal to that of the adjacent layers.
