摘要： In a projection display device provided with an optical unit, a power unit, and an outer case housing the optical and the power units, an air inlet opening (75) is formed at one end section of the power unit and an air outlet opening (77) is formed at the other end section. The opening (75) is provided near the air inlet of the outer case. Since the power unit is provided with the inlet openings (75 and 77), the inside of the power unit can be cooled independently with high efficiency, and the optical and the power units can be arranged closely to each other.

摘要： A projection type display device which prevents light from a dichroic prism (910) constituting color synthesis means of an optical system, etc., from entering the back side of a liquid crystal light valve. The dichroic prism (910) comprises four triangular prisms having an equal refractive index, and a glass filter (912) for absorbing and cutting off a blue luminous flux is bonded to the incidence surface (910R) of a red luminous flux. After passing through each light valve (925), a modulated luminous flux of each color passes through a prism unit, is reflected by its X-shaped reflection surface and is directed toward the projection lens unit 6. At this time, part of the blue luminous flux may not be reflected by the reflection surface but incident on the back of the red light valve (925R). Light leaking from the prism in this way is absorbed and cut off by the filter (912). Accordingly, it is possible to prevent the erroneous operation of the liquid crystal light valve due to the entrance of light from the back surface.
摘要翻译：一种防止来自构成光学系统的颜色合成装置等的二向色棱镜（910）的光进入液晶光阀背面的投射型显示装置。二向色棱镜（910）包括具有相同折射率的四个三棱镜，并且用于吸收和切断蓝色光束的玻璃滤光器（912）被结合到红色光通量的入射表面（910R）。在通过每个光阀（925）之后，每种颜色的调制光通量通过棱镜单元，被其X形反射面反射并被指向投影透镜单元6.此时，部分蓝色光通量可能不被反射表面反射，而是入射到红光阀（925R）的背面。以这种方式从棱镜泄漏的光被过滤器（912）吸收并切断。因此，可以防止由于来自背面的光的入射引起的液晶光阀的错误操作。

摘要： A projection display device (1) is provided with a light source lamp unit (8), an optical lens unit (9), a projection lens unit (6), and a power source unit (7). The lens unit (6) is positioned at the front side of the enclosure (2) of the display device (1) and the lamp unit (8) is positioned at the rear side of the enclosure (2). The lens unit (9) is stacked on the power source unit (7) between the units (6 and 8). Since the bulky units (9 and 7) are stacked in such a way, the dimensions of the whole body of the display device (1) can be reduced in both the longitudinal and transversal directions. Therefore, this portable projection display device does not require any large area for installation. Since the heavier unit (7) is on the bottom side, the device (1) becomes stable when placed on a desk, etc.

摘要： A projector for synthesizing and projecting an image of three primary colors formed by liquid-crystal light bulbs, wherein deviation in pixels and color shading are improved by correcting errors of the position and angles of mounting the liquid-crystal light bulbs and by eliminating effects on parts caused by the heat of the source of light. For this purpose, there are arranged a plurality of dichroic mirrors, for separating white light into three primary colors, liquid-crystal light bulbs of the three primary colors, and a dichroic mirror for synthesizing the image. The liquid-crystal light bulb of one color is arranged at a central portion of the housing, and the liquid-crystal light bulbs of the remaining two colors are arranged symmetrically with respect to the first one. Pixels of the two symmetrical liquid-crystal light bulbs are adjusted for their positions relative to each other with respect to pixels of liquid-crystal light bulb in the center.

摘要： A liquid crystal panel unit (50R) is attached to the light incident face (22R) of a prism combination (22). This unit (50R) has a light valve frame plate (51) retaining a liquid crystal panel (40R), and a fixed frame plate (54) fixed to the light incident face (22R) by an adhesive layer (A1). The light valve frame plate (51) is screwed to the side of the fixed frame plate (54) through an intermediate frame plate (55). The liquid crystal panel (40R) retained there can be positioned and fixed surely by adjusting the position of the light valve frame plate (51) with respect to the light incident face (22R), using a wedge-shaped member (57), so the focus adjustement can be performed with accuracy, suppressing the misregister of picture elements, therefore high precision becomes possible easily. Then, the fixed frame plate (54) and the light valve frame plate (51) consist of the materials whose linear expansion coefficients range from a quarter to four times and one-fifth to five times the linear expansion coefficients of the said prism synthesizer (22) and the fixed frame plate (54), respectively.

摘要： The internal space of an optical lens unit (9) of a projection display (1) is kept under a substantial hermetic state by light guides (901, 902) defining its outer peripheral surface, an upper seal plate (981) fitted to its upper portion, a lower seal plate (1150) fitted to its lower portion and a head plate (903) on its front side. An air circulation flow (1180) that circulates in a vertical direction is formed by a circulating fan (15B) disposed between liquid crystal light bulbs (925R, G, B) and the lower seal plate (1150). While this air circulation flow (1180) runs along the lower surface of the upper seal plate (951), its emits its heat to external air introduced to the upper surface of the upper seal plate (991). While the air circulation flow (1180) runs through air flow passages (1160, 1170) passing through heat radiation portions (5R, 5L) formed in a front case through a vent hole of the head plate (903), it emits its heat to the outside. Each internal portion can be efficiently cooled by sufficiently cooled air circulation flow (1180). Dust, etc., does not enter from outside because it is the circulating flow.
