摘要： A transmissive, backlit color twisted-nematic or super-twisted-nematic liquid crystal display employing a front fiber-optic faceplate as a front retaining element of a liquid crystal cell that increases viewing angle between the display and a viewer while minimizing or eliminating undesirable variations in luminance, contrast ratio and chromaticity is described. This novel configuration effectively decouples the liquid crystal cell and other optical elements behind the front fiber optic faceplate from the angular orientation of the viewer with respect to the display. The liquid crystal display described in this invention further provides a high quality color display, without viewing parallax, using a color selection filter mosaic outside of the liquid crystal cell. The display also increases luminous efficiency and improves color saturation by concentrating the transmission of available backlight illumination through the use of a rear fiber-optic faceplate and a second rear-mounted mosaic of color interference filters.

摘要： A full color display is disclosed having a high efficiency light source optically coupled by a light coupling lens array to the active matrix of pixel elements of an image forming means such as a transmissive liquid crystal light valve. The light source is comprised of a patterned matrix of individual, primary colored visible radiation emitters, such as individual phosphor elements, arranged in a manner suitable for the human eye to integrate the individual primary colored lights into a single mixture color. The light coupling lens array collects substantially all of the light rays emitted from each primary colored light emitter and focuses them on a respective one of the transparent electrodes in the active matrix, as a real image smaller than the size of the electrode. A suitable light coupling lens array is a gradient index lens array, a multiple layer, two dimensional array of microlenses functionally analogous to an array of strip lenses, or a microlens array. A twisted nematic liquid crystal cell may be used in the image forming means to achieve a high contrast display. Use of the light coupling lens array to collect and focus the light rays from the light source permits the focused light to pass through an entrance polarizer with minimal scattering or divergence, and then through the respective transparent electrode in the active matrix unobscured by the opaque pixel interconnect elements. More efficient use of a larger percentage of the light from the light source in this manner results in the formation of a bright, high contrast, full color image.

摘要： A full color, liquid crystal display device is disclosed having two optical paths, the first for long (red) and medium (green) wavelength regions of the visible light spectrum, and the second for the short (blue) wavelength region of the visible light spectrum. The two optical paths and their properties are nominally matched to the characteristics of the chromatic and luminance processing channels of the human visual system. The two-path device generates two separate, spatially coherent color images using two liquid crystal light valve image forming sources, without the use of color filters typically found in full color displays. The two images are combined by additive spatial superposition to produce a single, full-spectrum, composite color image. In one embodiment, individual red and green light components from an efficient, patterned backlight of individual red and green light emitters are coupled by a light coupling lens array to respective display pixels in the liquid crystal light valve. In another embodiment, red and green light components form a red and green image by passing through two aligned liquid crystal light valves and two color selecting polarizers. A light coupling lens array couples the light from one liquid crystal light valve to the other. Suitable light coupling lens arrays in both embodiments include a SELFOC lens array, a strip lens array, or a microlens array. The composite image may be either directly viewed or optically projected using a conventional projection lens assembly onto an intermediate viewing surface.

摘要： The present invention is directed to a driving method for compensating the response speed change of an electrophoretic display due to temperature variation, photo-degradation or aging of the display device, without a complex structure (e.g., use of sensors). This is accomplished by combining two waveforms, one of which causes the grey level to become dimmer and the other waveform causes the grey level to become brighter, as the response speed degrades.

摘要： The color display of the present invention involves a two particle system and is capable of displaying multiple colors with high quality black and white states. The color states are suitable for highlighting function. The color display does not require alignment between the electrodes and the display cells in which a display fluid is filled, which significantly reduces the complexity of the design and also lowers the manufacturing costs.
