    摘要： A flat panel display that is convertible between direct and projection display applications is incorporated in an information processing device of a unitary construction. In preferred embodiment, the information processing device is selectively configurable as a laptop-style personal computer and a projection display panel. The device includes a base section that contains computer circuitry, supports data input keys, and is pivotally coupled to a display panel section having an addressable flat panel display and an opaque backing member in opposed face-to-face relation thereto. The display panel section is selectively positionable between a first position in which the flat panel display is directly observable by a user, a second position in which the backing member covers the flat panel display and the data input keys for storage purposes, and a third position in which the display panel section is generally nonoverlapping and co-planar with the base section.

    摘要： On the outside of a body of a projector, an LCD is provided for displaying an image. A lamp is incorporated in the projector body for illuminating from the rear an image displayed on the LCD. A movable member is provided on the outside of the projector body for vertical swinging movement between open and closed states, and, in the closed state, allows the LCD to be directly observed. A projecting head is provided on the movable member for projecting, in the open state, the image illuminated by the lamp onto a screen outside the projector body.

    摘要： The invention relates to the field of LCDs, and more particularly to an LCD module with projection function and an LCD device including the LCD module. The LCD module includes a light source, a light guide panel, and a backplane, and further includes a projection module sharing the light source of the LCD module, and a switching mechanism for switching liquid crystal display and projection. The LCD module of the invention is used for liquid crystal display in a usual state, the display mode is changed into a projection mode by the switching mechanism when the size of an LCD screen cannot meet the display requirement, and the projection area is large and can basically meet the requirement. The invention has the advantages of one machine with dual-purpose and convenient operation; in addition, a projector is integrated with the LCD module by the invention, and the light source of the LCD module is shared with the projection module by clever design, thus, a simple structure is obtained, and the cost of the device is well controlled.

    摘要： It is possible to eliminate a fringe pattern produced at the time of incidence of polarized light of a light distribution control element, in which stray light derived from outside unnecessary light in a liquid crystal display apparatus of the like can be effectively reduced, and bright, wide viewing angle characteristics can be achieved when the display is viewed at any angle by an observer. In a light distribution control element constituted of a transparent base member, an array of a plurality of micro-lenses (transparent beads densely arrange on the transparent base member and a light absorbing layer having very small opening portions substantially at focal positions of the micro-lenses, the transparent base member is constituted of a transparent body which is substantially isotropic optically or a transparent body having uniaxial optical anisotrophy.

    摘要： An optical system and an imaging and display system using the optical system. The optical system has at least first and second optical elements aligned on a common axis. In one embodiment, each of the first and second optical elements can operate in an active state or in inactive state and comprise a photopolymer and liquid crystal combination. Each of the first and second optical elements is configured to transmit incident light substantially unaltered when each of the first and second optical elements operates in the inactive state. In the active state, however, each of the first and second optical elements does not transmit incident light substantially unaltered. Rather each of the first and second optical elements substantially alters light incident thereon when each of the first and second optical elements operates in the active state.

    摘要： A transportable image display system having direct and projection viewing modes of operation. The image display system comprises a spatial light modulation structure for spatially modulating the intensity of light produced from a light source, and light diffusing panel of electro-optical construction having a light scattering state in which light being transmitted therethrough is scattered in a diffusive manner, and a light transmission state in which light being transmitted therethrough is transmitted without substantial scattering. In the illustrative embodiments, the spatial light modulation structure can be an electrically-addressable LCD panel, or slide-film structures to be viewed. During the direct viewing mode, light produced from the light source is scattered by the light diffusing panel and spatial intensity modulated by the spatial light modulation structure to form a first image for direct viewing. During the projection viewing mode, light produced from the light source is transmitted through the light diffusing panel without substantial scattering and spatial intensity modulated by the spatial light modulation structure to form a second image for projection onto a projection display surface for projection viewing.
