Abstract
An image display device includes a light source which emits laser light; an optical system which is operable to switch between a direct viewing mode of modulating the laser light and displaying the modulated light on a display section, and a projection mode of modulating the laser light and projecting the modulated light on a projection plane; and a control circuit which controls the optical system. The control circuit sets the optical system to the direct viewing mode at the time of activating an electric power source of the image display device.
Claims14
An image display device, comprising:
- a light source;
- an optical system which is operable to switch between a direct viewing mode of modulating light from the light source and displaying the modulated light on a display section, and a projection mode of modulating the light from the light source and projecting the modulated light on a projection plane;
- and
- a control circuit which controls the optical system, wherein
- the control circuit sets the optical system to the direct viewing mode at the time of activating an electric power source of the image display device.
A portable terminal device, comprising:
- an image display device including:
- a light source;
- an optical system which is operable to switch between a direct viewing mode of modulating light from the light source and displaying the modulated light on a display section, and a projection mode of modulating the light from the light source and projecting the modulated light on a projection plane;
- and
- a control circuit which controls the optical system,
- wherein
- the control circuit sets the optical system to the direct viewing mode at the time of activating an electric power source of the portable terminal device.
