摘要： A lighting unit and a liquid crystal display device which can improve the efficiency of usable light. The lighting unit includes a light source, a light guide plate, and a truncated pyramid located between the light guide plate and the light source. The truncated pyramid has a base, a top smaller than the base, and a slope linking the base and the top. The light source is placed in close contact with the top of the truncated pyramid, and the light guide plate is placed in close contact with the base of the truncated pyramid. Light is propagated from a light emitting part of the light source to the light guide plate without passing through any air layer. Also, an unnecessary light removing structure is provided in the light guide plate near the incidence surface thereof.

摘要： The invention relates to a backlight unit for liquid crystal displays, etc.; and its object is to provide a backlight unit not involving the problem that the emitted light leaks out of the optical waveguide, even when the space around the cold-cathode tubes in the light source unit for it is filled with a liquid of which the refractive index is nearly the same as that of the glass material that forms the outer wall of the cold-cathode tubes. The backlight unit comprises a housing 6 which houses cold-cathode tubes 2, 4 therein and of which the inner surface is coated with a light reflector 10; a transparent liquid filled in the housing 6; and an optical waveguide 1 made of a transparent substance and having a light-emitting surface S. The reflective surface of the light reflector 10 has a cross-section profile of X-T-U-V-W-Y, on which the light emitted by the cold-cathode tubes 2, 4 is reflected, and the thus-reflected light is led to the light-emitting surface S of the optical waveguide 1 at an incident angle not smaller than the critical angle to the surface S.

摘要： There is provided a liquid crystal display having good display characteristics and a method of driving the same. Pixel data is written in plural pixels on one gate bus line at a top end of a display area at a first point in time on a line sequential basis. At a second point in time, the writing of pixel data in pixels in an upper part of the screen is completed, and writing of pixel data in pixels in a lower part of the screen is started. At a third point in time, the writing of pixel data in the pixels in the lower part of the screen is completed. A fluorescent tube on the upper side of the screen is turned on for a period between a third point in time after the writing of pixel data in the upper part of the screen and a fourth point in time before writing of pixel data for the next frame is started and is turned off in other periods. A fluorescent tube on the lower side of the screen is turned on for a period between a fifth point in time after the writing of pixel data in the lower part of the screen in the preceding frame and a sixth point in time before writing of pixel data in the lower part of the screen is started and is turned off in other periods.

摘要： The present invention relates to a light source device including discharge tubes that emit light by discharging in a thin atmosphere, a method of producing the light source device, and a display apparatus in which the light source device is employed. This light source device includes discharge tubes and a heat conductive member that is brought into contact with the neighboring area of the electrodes of the discharge tubes so as to locally cool down the neighboring area of the electrodes. In the light source device, a low heat conductivity member having lower heat conductivity than the heat conductive member is interposed between the heat conductive member and the discharge tubes. With such a structure, the luminance in the entire light source device can be increased and made uniform, and the reliability of the light source device can be increased accordingly.

摘要： A liquid-crystal display includes a reflective liquid-crystal panel, a light guiding plate disposed on the reflective liquid-crystal panel, a polarizer arranged between a liquid-crystal layer of the reflective liquid-crystal panel and the light guiding plate, and a light source disposed on a side surface of the light guiding plate. Light emitted from the light source propagates through the light guiding plate and has a primary direction. A smaller one of two angles between a projection of the primary direction onto the reflective liquid-crystal panel and an absorption axis of the light guiding plate is at least 50°. This resultantly improves performance of the liquid-crystal display.

Each of the pixels of the spatial modulator includes a plurality of color dots arranged in a first direction. A length of a peripheral region of the respective pixel encircling the plurality of color dots, measured in the first direction, is longer than a length of the condenser element of the periodical structural body, measured in the first direction.

摘要： A projector includes a first housing, a second housing, and a sound insulating member. The first housing is provided with first heat-generating elements used for generating an image, first fans producing cooling airflows towards each one of the first heat-generating elements, and vents via which the cooling airflows heated by the first heat-generating elements are discharged. The second housing encloses the first housing, and has second fans discharging the cooling airflows outside the projector. The sound insulating member is provided on a path between the vents and the second fans so as to insulate sound produced by the first fans. The projector may be provided with a dust-proof member for the projecting lens.
