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 |
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 |
20120194934 | REFLECTIVE DISPLAY DEVICE - A reflective display device includes a first absorption layer configured to be modulated between being strongly and weakly absorbing of light within a first specified wavelength band and to absorb light weakly in a second specified wavelength band and a third specified wavelength band, a second absorption layer configured to be modulated between being strongly and weakly absorbing of light within the second specified wavelength band and to absorb light weakly within the third specified wavelength band, a third absorption layer configured to be modulated between being strongly and weakly absorbing of light within at least the third specified wavelength band, and at least one reflector arranged between two of the first, second, and third absorption layers, the at least one reflector being configured to reflect light strongly within one of the specified wavelength bands assigned to the absorption layers above the at least one reflector. | 08-02-2012 |
