Abstract
An image display apparatus is provided that allows a user to check image content even in a place where there is no projection screen. A projector that is one mode of the image display apparatus includes a casing, a projection aperture provided in the casing, and an internal projection mirror and a built-in screen that are provided in a casing. When the projector is being folded, laser light emitted from the projection aperture is reflected by the internal projection mirror. The reflected light is projected onto the built-in screen, whereby an image is displayed.
Claims6
An image display apparatus comprising:
- a first casing;
- a second casing;
- a third casing, said first casing and said second casing being configured to be foldable relative to each other, and said second casing and said third casing being configured to be foldable relative to each other;
- a light source that emits laser light;
- a projecting unit disposed in said first casing and configured to project laser light outside said image display apparatus;
- a screen disposed in said third casing and receiving an image to be projected;
- and
- a reflecting unit disposed in said third casing and configured to reflect the laser light from said light source toward said screen,
- wherein the screen receives an image to be projected when the image display apparatus is in a folded position in which the first casing and the second casing are folded relative to each other, and the second casing and the third casing are folded relative to each other.
An image display apparatus comprising:
- a first casing;
- a second casing;
- a third casing, said first casing and said second casing being configured to be foldable relative to each other, and said second casing and said third casing being configured to be foldable relative to each other;
- a light source that emits laser light;
- a projecting unit disposed in said first casing and configured to project laser light outside said image display apparatus;
- a screen disposed in said third casing and receiving an image to be projected;
- a reflecting unit disposed in said third casing and configured to reflect the laser light from said light source toward said screen;
- and
- a detecting unit configured to detect movement of said first casing;
- and a control unit configured to control light emission by said light source, in response to said movement detection,
- wherein said control unit is configured to suppress an output from said light source to a preset output or less.
