Patent ID: 7826125

Claim:
A light conductive controlled shape droplet display device, the device comprising: a light source; a light conductive substrate receiving and conducting light from said light source; a cover disposed relative to said light conductive substrate, said cover conducting light received from said light conductive substrate out and away from said display device; and a plurality of pixels, each pixel being defined by a fluid droplet in optical communication with said light conductive substrate and said cover; at least one hydrophobic layer associated with said light conductive substrate or said cover for controlling the shape of said fluid droplet, properties of said fluid droplet and said at least one hydrophobic layer being set to shape said fluid droplet to conduct a predetermined amount of light through said fluid droplet and into said cover under a condition of no voltage potential applied to said fluid droplet; and electrodes arranged to modulate the amount of light conducted by said fluid droplet from said light conductive substrate into said cover by application of a voltage potential to said fluid droplet.
