Abstract
A display device includes: a display that emits image light; an optical element that is disposed away from the display, the optical element being switchable between a first state in which the optical element reflects the image light and a second state in which the optical element transmits the image light; a first reflector that is disposed on an opposite side of the optical element relative to a side on which the display is disposed; and a controller that controls the display and the optical element. When the controller causes the display to repeatedly output a first image and a second image in an alternating manner, the controller switches the optical element between the first state and the second state in synchronization with the first image and the second image.
Claims16
A display device comprising:
- a display that emits image light;
- an optical element that is disposed away from the display and facing the display, the optical element being switchable between a first state in which the optical element reflects the image light and a second state in which the optical element transmits the image light;
- a first reflector facing the optical element and reflecting the image light that has transmitted through the optical element toward the optical element;
- and
- a controller that controls the display and the optical element,
- wherein, in the second state, the image light emitted from the display and transmitted through the optical element is reflected by the first reflector and then directly transmitted through the optical element, and
- when causing the display to repeatedly output a first image and a second image in an alternating manner, the controller switches the optical element between the first state and the second state in synchronization with the first image and the second image.
A display device comprising:
- a display that emits image light;
- an optical element that is disposed away from the display, the optical element being switchable between a first state in which the optical element reflects the image light and a second state in which the optical element transmits the image light;
- a first reflector that is disposed on an opposite side of the optical element relative to a side on which the display is disposed;
- and
- a controller that controls the display and the optical element,
- wherein, when causing the display to repeatedly output a first image and a second image in an alternating manner, the controller switches the optical element between the first state and the second state in synchronization with the first image and the second image, and
- wherein, when the first image is defined by the image light displayed when the optical element is in the first state and the second image is defined by the image light displayed when the optical element is in the second state,
- the controller:
- (i) causes the display to output the first image to gradually reduce a size of the first image from an initial size to a first predetermined size, while keeping the optical element in the first state, the first predetermined size being smaller than the initial size;
- (ii) switches the optical element to the second state after the size of the first image reaches the first predetermined size;
- (iii) causes the display to output the second image to gradually reduce a size of the second image from a second predetermined size to a third predetermined size, while keeping the optical element in the second state, the second predetermined size being smaller than the first predetermined size, the third predetermined size being smaller than the second predetermined size;
- (iv) causes the display to output the second image to gradually increase the size of the second image to the second predetermined size, when the size of the second image reaches the third predetermined size;
- (v) switches the optical element to the first state after the size of the second image reaches the second predetermined size;
- and
- (vi) causes the display to output the first image to gradually increase the size of the first image from the first predetermined size to the initial size, while keeping the optical element in the first state.
