    摘要: The present invention provides an inexpensive projection display that allows a pixel grid as ineffective portions of respective pixels of a light valve to be made inconspicuous. The projection display includes a birefringent element (43) for spatially separating light from a transmission liquid crystal light valve (39). The birefringent element (43) includes a first birefringent plate (40) that the light from the liquid crystal light valve (39) enters, a second birefringent plate (41) that light from the first birefringent plate (40) enters, and a third birefringent plate (42) that light from the second birefringent plate (41) enters. A polarization direction of the light entering the first birefringent plate (40) forms an angle of n×45° (n is an integer other than 0) with an optic axis of the first birefringent plate (40) projected on an incident surface of the first birefringent plate (40). An optic axis of the second birefringent plate (41) projected on an incident surface of the second birefringent plate (41) is orthogonal to the optic axis of the first birefringent plate (40) projected on the incident surface of the first birefringent plate (40). An optic axis of the third birefringent plate (42) projected on an incident surface of the third birefringent plate (42) extends horizontally or vertically.

    摘要: A light source device has: a light source unit including solid-state light sources emitting blue-color light and a condensing lens; a dichroic mirror polarization separating color light into first and second polarization components; a fluorescence emission plate excited with the first polarization component, emitting fluorescence of green and red components to enter the dichroic mirror; a first retardation plate converting the second polarization component to a circularly polarized light; and a reflection plate reflecting a light passed through the first retardation plate to reenter the same. The color lights from the fluorescence emission plate and the first retardation plate are combined at the dichroic mirror. A second retardation plate converts the polarization direction of the light from the light source unit, so as to control the ratio of p-polarization and s-polarization components. Lights from solid-state light sources are condensed efficiently and a high spectrum-utilization factor is obtained.

    摘要: A light source device includes a phosphor layer formed on a base, and an excitation light source exciting the phosphor. A dichroic mirror is arranged between the phosphor layer and the excitation light source and inclined with respect to a propagation direction of excitation light from the excitation light source. An incident region of the excitation light and an exiting region of fluorescence emitted from the phosphor belong to a space on the same side with respect to the surface with the phosphor layer disposed. In a dominant wavelength of the excitation light, the dichroic mirror has a spectral characteristic of transmitting 50% or more of light of a p-polarized component and reflecting 50% or more of light of a s-polarized component. Fluorescence emitted from the phosphor layer can be extracted highly efficiently and propagated by a compact and simple optical system.

    摘要: A starter driving semiconductor switch apparatus energizes and de-energizes a starter according to a command from an outside. A series circuit to which semiconductor switches are connected in series is provided between a battery serving as a power supply and the starter. The starter is energized by bringing all the semiconductor switches into conduction. A voltage or a current at a predetermined point in the series circuit is monitored to make a self-diagnosis on whether the starter is allowed to start and whether there is a failure in the semiconductor switches according to a monitor output. The starter driving semiconductor switch apparatus is thus expected to have a longer useful life by energizing the starter not by using mechanical contacts but by using semiconductor switches.

    摘要: Provided are an illumination optical system allowing light beams to be condensed and enter an illumination area at different angles from each other, color separating elements that separate colors of the light beams from the illumination optical systems, liquid crystal light valves that modulate the color lights to form image light for the right and the left eyes, a color combining element that combines the color light beams, a wavelength-selective polarization rotating element that rotates the polarization direction of a predetermined color light so as to align the polarization direction with that of a light beam of another color, and a projection lens that magnifies and projects images. The liquid crystal light valves are provided with an incident side microlens array that causes the light beams for the right and the left eyes to pass respectively through the right and the left eye image pixels, and an exit side microlens array that condenses the light that has passed through the pixels. The projection lens is provided with a polarized light separating element that causes the polarization directions of image light for the right and the left eyes to be orthogonal to each other. Using one projection-type display apparatus, a highly efficient stereoscopic image can be displayed with little flicker and cross talk of image light for the right eye and for the left eye.
