摘要： An optical display system includes a light source, a color wheel, an optical train and a light valve. The optical train includes a diffuser element, a compound parabolic concentrator and an integrator. The diffuser element diffuses incoming light to fill in holes in cone half-angle distribution of light generated by the light source. The compound parabolic concentrator reduces the cone half-angle of the diffused light to a cone half-angle expected by the light valve. The integrator reduces hot spots in the diffused light. The color wheel may modulate optical path length of light traveling through the color wheel. Modulating the optical path length reduces coherence in the light generated by the light source. A color wheel that reduces coherence would allow the light source to be laser or LED-based. If the light valve is a ferroelectric light valve, the color wheel may include pairs of polarizers. Light is polarized in orthogonal directions by the polarizers in a pair. This allows all of the light to be used by the ferroelectric light valve during dc balancing.
摘要翻译： 光学显示系统包括光源，色轮，光学列车和光阀。 光学系列包括漫射元件，复合抛物面聚光器和积分器。 扩散器元件扩散入射光以填充由光源产生的光的锥形半角分布中的孔。 复合抛物面聚光器将散射光的锥形半角减小到由光阀预期的锥形半角。 积分器减少漫射光中的热点。 色轮可以调制通过色轮行进的光的光程长度。 调制光程长度可减少由光源产生的光的相干性。 减少相干性的色轮将使光源成为激光或基于LED的。 如果光阀是铁电光阀，则色轮可以包括成对的偏振器。 光通过偏振器成对地在正交方向上偏振。 这允许在直流平衡期间所有的光被铁电光阀使用。

摘要： In accordance with the teachings of this invention, a novel liquid crystal display is taught which includes a layer of liquid crystal material, a thin transparent layer, one or more polarizers, and a fiber optic faceplate. The fiber optic faceplate serves to allow ambient light from a much wider range of incident angles to illuminate the LCD than would be the case with prior art LCDs, and allows the viewer to position himself so as to avoid front surface glare and still see the display brightly illuminated, even in difficult lighting situations.

摘要： A screen includes a first set of louver members at least partially disposed in the screen and located proximate to a first side of the screen, and a second set of louver members at least partially disposed in the screen and located proximate to a second side of the screen. An observer on either side of the screen sees an image produced by light directed to that observer by that set of louvers on the same side of the screen as the observer. Objects on the other side of the screen from the observer are visible to the observer between the louvers.

摘要： In a particular embodiment, a see-through display includes a screen having transparent layer of material with a front side and a back side. At least one plurality of shaped louver members is disposed between the front side and the back side. The plurality of the louver members allow transmission of a fraction of light through the screen with minimum scattering within a range of incident angles. The plurality of the louvers also redirect image signal light from an image source into a range of angles centered about a normal to the screen. The louver members combine the image signal light with the light emitted from background objects located on the backside of the screen. The background image light is transmitted through the display screen with minimal scattering. For embodiments providing two sets of louver members, the image signal light may be redirected to observers on either side of the screen, such that the observers may see each other as well as the intended image.

摘要： The present invention replaces liquid crystal light control elements in fiber-optic faceplate liquid crystal displays (LCD) with suspended particle devices (SPDs), and provides for passive light control without the need for either polarized light or special alignment layers. A fluid or film containing suspended particles may be asymmetric in shape so that their optical density depends strongly upon their orientation. The orientation of the particles within the fluid can be manipulated by an application of an electric field, so that the fluid or film may appear to be transparent to both polarizations of light when the electric field is applied, and opaque when the electric field is removed and the orientation of the particles is allowed to randomize naturally.

摘要： Significantly improving in the contrast ratio of a visual image display using a liquid crystal layer and a fiber optic faceplate with tilted fibers. One preferred embodiment of the visual image display includes a liquid crystal layer, a first polarizer and an optical fiber faceplate with many substantially parallel fibers. Each fiber has an axis which forms an oblique angle with the normal to the front surface of the liquid crystal layer. All the oblique angles are substantially equal to a typical oblique angle. The typical oblique angle is selected along the direction that substantially maximizes the contrast ratio of the display.
