Definitions
- the present invention relates to a head-mounted display that is used while being worn on a user's head.
- Head mounted displays that are used on the body such as the head and display images in front of the user's eyes are used in various fields for displaying images, including partial reality.
- the head-mounted display is generally formed in a gondal shape or a frame shape of large glasses.
- There is also a type of head mount display (hereinafter referred to as “mounting type HMD (Head Mount Display)”) that is used by being attached to a spectacle frame-shaped mounting member.
- mounting type HMD Head Mount Display
- the smaller the head-mounted display the better.
- a head-mounted display is more excellent in design as it has a size and shape that the user does not bother when attached to the user's head.
- the mounting type HMD allows the user to see the scenery in addition to the image from the head mounted display even when the head mounted display is attached.
- a display mechanism with a display is provided above the rim of the mounting member, and the image power output from the display mechanism is viewed by the user's eyes via a light guide means that enlarges the image at a predetermined magnification. It is supposed to enter.
- the light guiding means is usually provided at a position corresponding to the spectacle lens of the mounting member. By such a light guiding means, an image is projected from the front of the user's eyes.
- the display mechanism and the light guide means are connected so as to be aligned in the vertical direction when the user wears the mounting member. In such a configuration, the display mechanism is provided so as to protrude from the upper part of the mounting member. Saying that the zain nature is excellent, difficult.
- Patent Document 1 there is a head-mounted display as disclosed in Patent Document 1, for example, which uses a free-form curved prism to reduce the size of the head-mounted display.
- the head mount display of Patent Document 1 includes a display for displaying an image and a free-form curved prism for guiding light from the display to the eyes of the user.
