  • Patent number: 7984994
    Abstract: A projection optical system including a projection lens, a first mirror that reflects a light from the projection lens, and a second mirror that widens an angle of a light from the first mirror by reflecting the light projects a light modulated according to an image signal from an optical engine unit. A third mirror reflects a light from the projection optical system. A screen transmits a light from the third mirror. An optical axis of the projection lens substantially matches an optical axis of the second mirror, and the light from the optical engine unit is shifted to a specific side from the optical axis of the projection lens.

  • Patent number: 7789516
    Abstract: A thin projection type image display device with a low chin height includes a cabinet, a screen, a projection optical system, an optical path changing unit, and a reflecting unit. The screen is disposed on a front side of the cabinet. The projection optical system enlarges and projects an image formed by a display element, and the optical path changing unit is disposed on the bottom of the cabinet to reflect the image enlarged and projected by the projection optical system. The reflection unit is disposed obliquely to the screen and below the screen to reflect the image reflected by the optical path changing unit toward the screen. The projection optical system is disposed in a space above a horizontal plane perpendicular to the screen, behind the front side of the cabinet, and below an optical path of light incident on a bottom of the screen.
