20120038972 | REFLECTIVE DISPLAY PIXEL - Various reflective display pixels are provided. In one embodiment, among others, a reflective display pixel for modulating the return of incident visible light is provided that includes one or more stacked cells. Each cell includes a fluid containing a light absorbing medium capable of absorbing incident light in at least one specified wavelength band for that cell and a light returning medium capable of selectively returning at least a portion of the light within the specified wavelength band for that cell. In other embodiments, each cell includes a fluid containing a light absorbing medium capable of absorbing incident light in at least one specified wavelength band for that cell and a light returning medium capable of selectively returning at least a portion of visible light outside the specified wavelength band for that cell. | 02-16-2012 |
20120113367 | FULL-COLOR REFLECTIVE DISPLAY - A full-color reflective display pixel includes first and second independently addressable electro-optic layers, each layer being independently switchable between a first state in which the layer is configured to absorb at least one color region of visible light and a second state in which the layer is configured to transmit the at least one color region of visible light. A reflective color filter is located between the back surface of the first electro-optic layer and the front surface of the second electro-optic layer, the reflective color filter being subdivided into a plurality of sub-pixels in which each sub-pixel is configured to transmit a first color region of visible light and reflect a second color region of visible light. A broadband reflective layer is located behind the back surface of the second electro-optic layer. | 05-10-2012 |
20120120354 | CHOLESTERIC REFLECTOR - A cholesteric reflector ( | 05-17-2012 |
20120120489 | BIREFRINGENT DIFFUSER - A birefringent diffuser includes a first optical material and a first birefringent material. The first optical material and the first birefringent material are combined to form a planar layer. The planar layer has an internal pattern of the materials presenting a substantially uniform index of refraction for incident light which is substantially normal to the planar layer and exhibiting a varying index of refraction for at least a portion of light which is trapped in guided modes. | 05-17-2012 |
20120127406 | REFLECTIVE DISPLAY - A reflective display includes a display cell having a light incident wall, a second wall, and a reflective layer. A cholesteric liquid crystal fluid is disposed within the display cell between the light incident wall and the reflective layer and a plurality of pigment particles are movably suspended within the cholesteric liquid crystal fluid. | 05-24-2012 |
