摘要： A transmission screen has a refraction total reflection Fresnel lens plate, a stray light eliminating plate, and an image display plate. The stray light eliminating plate has a condensing lens array and black stripes. The array has unit lenses arranged at an incident plane of the transparent substrate in a periodic structure in an up-and-down direction. The black stripes have transparent sections placed near condensing light points of the unit lens and opaque sections around the condensing light points of the unit lenses. The sections are alternately arranged at the outgoing plane of the transmission substrate in a periodic structure in an up-and-down direction. The image display plate has lenticular lenses in which unit lenses are arranged in a periodic structure in a horizontal direction at an incident plane of the transmission substrate of a scattering characteristic capable of scattering light fluxes.

摘要： A field-sequential color image display device receives red, green, and blue image data, and decomposes the received data into more than three monochromatic images. The monochromatic images may include at least two red, two green, and two blue images. Alternatively, the monochromatic images may include one white image and at least one red, one green, and one blue image. The monochromatic images are displayed sequentially, each monochromatic image followed by another monochromatic image of a different color. The increased number of monochromatic images alleviates the problem of color breakup.

摘要： A display device scans a phosphor screen with three independently modulated ultraviolet beams. The screen is coated with three types of light-emitting phosphor dots, each emitting a different color of visible light when illuminated by ultraviolet light. A color separator such as an aperture mask or lens array directs each ultraviolet beam onto phosphor dots of one of these three types. Two or more of these display devices can be combined to obtain a larger screen size.

摘要： A projection display device capable of selectively operating in a front projection mode and a rear projection mode, comprises a projector (300) disposed in a cabinet, a rear projection screen formed in a wall of the cabinet, and a front projection screen disposed outside the cabinet. To permit selection between the front and rear projections, the projector may be detachably mounted on the cabinet: when it is mounted the image rays (110) are introduced into the cabinet for the rear projection, while when it is detached it can be used for the front projection. In another embodiment, a selective light guide directs the image rays either to the rear projection screen or to the front projection screen. In a further embodiment, the rear projection screen can change between transparent and translucent states. When it is transparent, the image rays are passed therethrough to the front projection screen.

摘要： Each of a plurality of Fresnel prisms 12 is formed so that a refractive surface 12 thereof includes a non-light incidence surface 12c upon which any light ray emitted from a projector 1 is not directly incident because it is intercepted by another Fresnel prism 12, the non-light incidence surface having an angle τ′ with a reflective surface 12b which is different from the prism apex angle τ of each of the plurality of Fresnel prisms. As a result, a light ray reflected by the refractive surface 12a of each of the plurality of Fresnel prisms without passing through the refractive surface can be preventing from emerging, as unnecessary light, toward the viewer's line of sight.
