    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: 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: 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.

    摘要: The present invention relates to a projection type display using a transmission type liquid crystal light valve, and its object is to supply a projection type display capable of exhibiting a high quality gradation display by preventing a leak current at a switching device. The projection type display comprises three liquid crystal light valves 21R, 21G, and 21B which have polarizing plates 20Rp, 20Gp, and 20Bp, modulate in intensity and emit each light of color components of red, green, and blue, and a dichroic prism to synthesize exiting lights from respective light valves. The projection type display is structured to arrange half-wave plates 20Ri, and 20Gi between the liquid crystal light valves 21R, and 21G for red and green, to set a polarizing direction of an exiting light of a blue component orthogonal to polarizing directions of the other two exiting lights.
