Title: DISPLAY DEVICE, METHOD FOR CONTROLLING DISPLAY DEVICE, AND MOVING BODY INCLUDING DISPLAY DEVICE
Abstract:
The present invention advantageously reduces the moving range of a screen. A screen (1) has an inclined surface relative to a reference surface (503). A drive unit moves the screen (1) in a moving direction (X) perpendicular to the reference surface. A control unit secures the screen along the moving direction when forming a first virtual image (301) on a first virtual surface (501) with a tilt angle α relative to the optical axis of a projection unit at less than a prescribed value. The control unit moves the screen in the moving direction (X) when forming a second virtual image (302) on a second virtual surface (502) with a tilt angle β relative to the optical axis of the projection unit at greater than a prescribed value.
