    摘要： A lighting unit including a light-reflecting reflector, a plurality of cold cathode tubes disposed inside the reflector and an optical waveguide connected with an open end of the reflector to guide the light emitted by the cold-cathode tubes. The reflector has a reflective surface that reflects the light having been emitted by the cold-cathode tubes in the direction nearly perpendicular to the wall of each tube, and only in a direction in which the light reflected does not re-enter the cold-cathode tubes. In another embodiment, the lighting unit may include a second optical waveguide disposed in the space between the cold-cathode tube and the reflector, wherein a space is formed between the cold-cathode tube and the second optical waveguide.

    摘要： The projection type display apparatus has liquid crystal panels with polarizers, a light source, a power supply, and a ballast. A cooling device is arranged in the apparatus such that a first set of cooling fans blow cooling air to cool the liquid crystal panels and the polarizers, and a second set of cooling fans suck the cooling air passing through the liquid crystal panels and the polarizers and blow the cooling air to independently cool the light source, the power supply, and the ballast. Therefore, a projection type display apparatus with little light leakage and low noise can be realized. The invention also provides a cooling unit, for the light source, which includes a movable lamp house and a duct with a cooling fan.

    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.
