    摘要: A polymer dispersed liquid crystal (PDLC) display element for use in an electronic apparatus wherein the display element operates in a PDLC mode or reverse PDLC mode providing for reduction of visual display haze, improved display contrast. The particular medium includes a liquid crystal portion and a polymer portion and may include a chiral component. In cases where visual display haze and contract is a particular problem in the utility of the reverse PDLC display element, such as in the case where the display element is combined with a solar battery, a sufficient amount of dichroic dye is added to the liquid crystal portion of the medium, and, further, a compound showing no fluorescence emission with respect to a liquid crystal portion, or a polymer or a chiral polymer precursor portion of the medium, is employed. The resulting electronic apparatus can, therefore, incorporate a reverse PDLC type display element in combination with a solar battery or other component that affects display quality in such elements to improve the overall visual quality and contrast in the display rendering the display more useful in more miniaturized applications.

    摘要: On the substrate (108) are made reflecting type picture element electrodes (107), of Cr, and on substrate 101 are made transference picture element electrodes (102), of ITO. On both substrates (108, 101) parallel alignment films (106, 103), consisting of polyimide alignment films, are each made, but rubbing treatment is not administered. Between the substrates (108. 101) polymer dispersion liquid crystal, in which liquid crystal (105) and polymer (104) are in a state of mutual orientation dispersion, is placed. Liquid crystal (105) is parallel oriented randomly near the substrate surfaces, and twisted approximately 90.degree. between the substrates (101, 108). Also, the orientation domains from the liquid crystal random orientation are evenly multidomained at the level of approximately 1-3 .mu.m. Because they are randomly oriented in this way, directivity of scatter is improved, and operation voltage is decreased.

    摘要: A polymer dispersed liquid crystal display device includes a top substrate and a bottom substrate. First electrodes are provided on the top substrate and second electrodes are provided on the bottom substrate. Orientation are provided on the top and the bottom substrates. The orientation films are respectively rubbed in predetermined directions. A polymer material, a liquid crystal material and a predetermined amount of a chiral agent are interposed between the top and bottom substrates. The polymer material is separated from the liquid crystal material through irradiation by ultraviolet rays. The liquid crystal material and polymer material have a mutually orientated and dispersed structure. The liquid crystal material has a predetermined twisting angle in a predetermined twist direction. As a result, light is scattered when substantially normal to the liquid crystal display device and the surface of the top substrate. Thus, a polymer dispersed liquid crystal display device is obtained that is particularly bright in a specific direction.

    摘要: In the moving image display device of the invention, a synthesis circuit inputs signals representing specified values of pixel rate factors R2 and R3 from a pixel rate factor specification circuit, while inputting overscanned frame image data D1 in the units of pixels from a 1st latch circuit. The synthesis circuit extracts a preset number of pixels corresponding to the specified value of the pixel rate factor R2 from a prior frame image, while extracting a preset number of pixels corresponding to the specified value of the pixel rate factor R3 from a latter frame image. The positions of pixels to be extracted from the latter frame image are complementary to the positions of pixels to be extracted from the prior frame image. The synthesis circuit combines the extracted pixels of the prior frame image with the extracted pixels of the latter frame image by a logical OR operation to generate intermediate frame image data D2. This technique of the invention is significantly simpler than the prior art technique but still effectively prevents flicker in a moving image to ensure smooth display of the moving image.
