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.

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： There is disclosed a display device using a color wheel having a color filter Cw, in addition to normal color filters corresponding to the three primary colors. The filter Cw has almost flat spectral transmission characteristics. Brightness information included in a color image signal is quantized with (n+m) bits. Information corresponding to the lower-order n bits is displayed by light transmitted through the filter Cw. Information corresponding to the upper-order n bits is displayed by light transmitted through the normal color filters. Only brightness information to which the human eye is visually sensitive is reproduced by the filter Cw having a lower transmissivity. This can eliminate a lack of the number of gray levels due to a constraint on the minimum switching speed of a light valve. Furthermore, the brightness little deteriorates.
摘要翻译：除了与三原色相对应的普通滤色器之外，还公开了使用具有滤色器Cw的色轮的显示装置。滤波器Cw具有几乎平坦的频谱传输特性。包含在彩色图像信号中的亮度信息用（n + m）位量化。通过滤波器Cw传输的光显示与低阶n位对应的信息。与通过普通滤色器透射的光显示与上位n位对应的信息。仅通过具有较低透射率的滤光器Cw再现人眼视觉敏感的亮度信息。这可以消除由于对光阀的最小切换速度的限制而导致的灰度级数的缺乏。此外，亮度稍微恶化。

摘要： In an image display which reproduces a color image by using lights color-separated into four or more colors through color filters, the objects of the invention are to effectively utilize the energy of light from a light source and to reduce the effect that a slight shift of the spectral transmittance characteristics of the color filters exerts on the spectral distributions of the lights after color separated. In an image display having a light source and four or more kinds of color filters and for color-separating light emitted from the light source into four or more colors through the four or more kinds of color filters and reproducing a color image by using the color-separated lights, the spectral transmittance characteristics of the color filters are set so that the cutoff wavelengths of the four or more kinds of color filters exist in a wavelength region in which the spectral distributions obtained by multiplying the spectral emissivity characteristic of the light emitted from the light source by the color matching functions are smaller than the values obtained by multiplying the average values of the spectral distributions in the wavelength region from 380 to 780 nm by an integer.
