Abstract
A display element has a plurality of pixels and is constructed to display image information by modulating light passing through each pixel. The display element has the following for each of the pixels: a mask having a shield portion in part; and a first fluid and an electroconductive or polar, second fluid being immiscible with each other. An amount of the light passing through the mask is regulated in such a way that a voltage applied to the second fluid of each pixel is varied to alter the shape of an interface between the first fluid and the second fluid, so as to increase or decrease light incident to the shield portion of the mask.
Claims8
A display element comprising a plurality of pixels and constructed to display image information by modulating light passing through each pixel, said display element comprising the following for each of the pixels:
- a mask having a shield portion in part;
- and
- a first fluid and a second fluid which are immiscible with each other, said second fluid being electroconductive or polar,
- wherein an amount of the light passing through said mask is regulated by a voltage applied to said second fluid of each pixel varied to alter the shape of an interface between said first fluid and said second fluid, so as to increase or decrease light incident to the shield portion of said mask.
A display device comprising:
- a light source;
- a display element comprising a plurality of pixels and constructed to display image information by modulating light passing through each pixel, said display element comprising the following for each of the pixels:
- a mask having a shield portion in part;
- and
- a first fluid and a second fluid which are immiscible with each other, said second fluid being electroconductive or polar,
- wherein an amount of light passing through said mask is regulated by a voltage applied to said second fluid of each pixel varied to alter the shape of an interface between said first fluid and said second fluid, so as to increase or decrease light incident to the shield portion of said mask;
- and
- a light guide to guide light from said light source to said display element.
