DISPLAY APPARATUS, DISPLAY METHOD, GOGGLE-TYPE HEAD-MOUNTED DISPLAY, AND VEHICLE
First Claim
1. A display apparatus which displays an image on a retina of a user, said display apparatus comprising:
- a light source which emits a beam including a visible light forming the image and an infrared ray; and
a transmissive deflection unit which includes a first surface facing an eye of the user, and a second surface that is a rear surface of said first surface,wherein said transmissive deflection unit has;
a transmissive characteristic for transmitting the visible light from a second surface side to a first surface side;
a deflection characteristic for deflecting, toward the eye of the user, the visible light projected from said light source to the first surface side; and
an infrared absorption characteristic for absorbing the infrared ray projected from said light source to the first surface side.

Abstract
A display apparatus includes a light source which emits a beam including visible light forming an image and infrared rays, and a transmissive deflection unit including a first surface facing the eyes of a user and a second surface which is a rear surface of the first surface. The transmissive deflection unit has transmissive characteristics for transmitting the visible light from the second surface side to the first surface side, deflection characteristics for deflecting, toward the eyes of the user, the visible light projected from the light source to the first surface side, and infrared absorption characteristics for absorbing the infrared rays projected from the light source to the first surface side.

12. A display method for displaying an image on a retina of a user via a transmissive deflection unit,
wherein the transmissive deflection unit includes: -
a first surface facing an eye of the user, and a second surface that is a rear surface of the first surface; a transmissive characteristic for transmitting a visible light from a second surface side to a first surface side; a deflection characteristic for deflecting, toward the eye of the user, the visible light projected from a light source to the first surface side; and an infrared absorption characteristic for absorbing an infrared ray projected from the light source to the first surface side, said display method comprising; emitting a beam including the visible light forming the image and the infrared ray; performing two-dimensional scanning on the first surface of the transmissive deflection unit, using the beam emitted in the emitting; and changing an output intensity of the infrared beam in the emitting according to a position on the first surface onto which the beam is projected for scanning in the scanning.
