Estimating the term…
A display device utilizes a plurality of pixels arranged in a predetermined configuration for recording and displaying information. Each pixel includes a substrate and a light modulating material for selectively modulating a predetermined wave length of light by transitioning between a first and a second state in response to a heater element. The light modulating material in the first state causes destructive interference in the predetermined wave length of light and in the second state causes constructive interference in the predetermined wave length of light. The pixel structure is buried within an aerogel thereby minimizing the heat dissipation rate from the pixels.
In a display device including a plurality of pixels arranged in a predetermined configuration, each said pixel comprising a substrate and a light modulating material for selectively modulating a predetermined wave length of light by transitioning between a first and a second state in response to pixel heating, wherein said material in said first state causes destructive interference in the predetermined wave length of light and in said second state causes constructive interference in the predetermined wave length of light, the improvements therewith comprising a layer of aerogel disposed beneath said light modulating material to increase the heat dissipation time for display operation.
In a display device including a plurality of pixels arranged in a predetermined configuration, each said pixel comprising a substrate and a light modulating material for selectively modulating a predetermined wave length of light by transitioning between a first and a second state in response to pixel heating, wherein said material in said first state causes destructive interference in the predetermined wave length of light and in said second state causes constructive interference in the predetermined wave length of light and the substrate includes periodically spaced mesas, wherein an area between said mesas defines a pixel cavity, the improvements therewith comprising a layer of aerogel disposed beneath said light modulating material to increase the heat dissipation time for display operation.
In a display device including a plurality of pixels arranged in a predetermined configuration, each said pixel comprising a substrate, a first insulating layer disposed on said substrate and a light modulating material for selectively modulating a predetermined wave length of light by transitioning between a first and a second state in response to pixel heating, wherein said material in said first state causes destructive interference in the predetermined wave length of light and in said second state causes constructive interference in the predetermined wave length of light, the improvements therewith comprising a layer of aerogel disposed beneath said light modulating material to increase the heat dissipation time for display operation.
