Projection type display device and image displaying method
First Claim
1. A projection type display device comprising:
- a light source;
a liquid crystal panel having a first image display area and a second image display area formed in one body and optically modulating light flux from the light source by the first image display area and the second image display area based on a first video signal and a second video signal, both inputted from an outside, thereby to produce a first image and a second image;
a projection optical system having an emitting part and projecting respective fluxes as projection light flux, which are obtained by optically modulating the light flux by the liquid crystal panel, from the emitting part;
a first screen for displaying the first image since the projection light flux is irradiated to the first screen;
a second screen arranged between the emitting part and the first screen in a direction perpendicular to the first screen for displaying the second image since the projection light flux is irradiated to the second screen; and
a support frame arranged on an outside part of the first screen to have an optical transparency, and defining respective fluxes of the projection light flux irradiated to the first screen and the second screen as a first partial flux and a second partial flux, respectively,wherein the second screen is arranged in such a position that the first screen is not overlapped with a shadow of the second screen which is produced since the projection light flux emitted from the emitting part is irradiated to the second screen,wherein an extension area of the second partial flux transmitted through the second screen intersects with the support frame.

Abstract
A projection type display device includes a image displaying element having image display areas for displaying a plurality of images respectively, a projection optical system having an emitting part for emitting projection light flux to the image display areas of the image displaying element, and a plurality of screens for displaying projected images by the projection light flux transmitted through the image display areas of the image displaying element. In the projection type display device, the image display areas are formed in respective areas in the image displaying element independent of each other. The projected images on the screens correspond to the image display areas, respectively. Each of the screens is arranged in such a position that the each of the screens is not overlapped with shadows of the other screens which are produced since the projection light flux is emitted from the emitting part to the screens.

6. An imaging displaying method comprising the steps of:
-
optically modulating light flux emitted from a light source at different areas in an image display area of a liquid crystal panel having a first image display area and a second image display area formed in one body, based on a first video signal and a second video signal, both inputted from an outside, thereby producing first light flux and second light flux; emitting projection light flux containing the first light flux and the second light flux produced from an emitting part of a projection optical system; displaying a first image based on the first video signal on a first screen arranged on an optical path of the first light flux so that at least part of the first screen intersects with the first light flux; and displaying a second image based on the second video signal on a second screen arranged between the first screen and the emitting part on an optical path of the second light flux so that at least part of the second screen intersects with the second light flux, wherein an extension area of the second light flux transmitted through the second screen intersects with a support frame, the support frame being arranged on an outside part of the first screen to have an optical transparency.
