[Technical field to which the invention belongs] The present invention relates to a head-mounted display system and system capable of adjusting the focal length when the head-mounted display is dry, and = ::, especially-and a device. The present invention can be applied to a head-mounted display. Display: A systematic method to adjust its focal length to suit the vision of the head wearer. , Y β can not adjust the image [previous technology installed in the United States, combined with the transmission of the image in order to avoid the installation of the optical element image generator lens conversion can be installed in glasses. And early use alone (in the United States display system, the processing signal display panel input magnifying lens is patented to send a production industry to fix the film to provide a unit or imaging user can use the patent 6, for example, the system can be light. The output signal amplifies the image of '36. The external high-quality manipulator can be used, while the head can be easily viewed on the 9,9 image device that allows the image inside the head-mounted case to be, but still The ΜΜ 影). 5 2 user view display device. From to. This device will be counter-allowed to allow D to put forward the head view separately. It is best to use a center cover that contains at least two covers that also contain the display screen from the direction of the user to use, so that the wearable display should be shielded by a shell. One can take off a penetrating type. The device has a conventional ΗMD capable of 3, 8 and 5 panels. The display system to be worn includes a light waveguide to be installed via the large substrate, and a display to be placed through the light waveguide. In combination with one or more systems, a wearable display can be adjusted according to a predetermined manner to guide a signal from the display grating, the number one, and the signal is displayed to form an optical waveguide. &" π 口 ν wk a ear wearable display system

The surface has at least the reflection / surface corresponding to the reflection. The first virtual image. However, the reflection should be reflected / amplified through the reflection, and the one should be viewed by the viewer. In the American system, the system display 5 is connected to a display on a display, making it possible to separately manufacture and install the optical waveguide in one step. Therefore, the most effort is applied to manufacture the head-mounted display system. Patent 5,99 1, 084 proposes a refined virtual image including / micro display, a first enlarged display input surface including three surfaces, a reflective / transmissive surface, and a reflective second surface, and a second Magnifying light device. The first magnifying light device that displays the target light entering the entrance surface. The light is at the first magnified light, so that the light is projected to an area of the back-reflective penetrating surface ', a portion of which is within the field of view provided by the second magnified light device. The reflection / transmission surface at the first angle of the transmission / transmission surface makes the transmission surface reflect, and guides the reflective first magnifying element to reflect the light corresponding to the source target. The magnified virtual image is The first magnifying light device is transmitted back to the reflecting / transmitting surface at a second incident angle of a pair of penetrating surfaces, and leaves the first magnifying light device. A plurality of the first sets receive the magnified virtual images from the first magnifying light device, and the composite target magnified virtual images of the source target are displayed as magnified virtual images.
