Description

1237125 V. Description of the invention (1) " '[Technical field to which the invention belongs]-The present invention relates to a head-mounted display, especially a head-mounted display system with adjustable focal length with digital content display = and its application In order to realize the installation of the system, the present invention can adjust the focal length of the image displayed on the head-mounted display to suit the vision of the head-wearer. [Prior art] In USP No. 6,369, 952, a head-mounted display is proposed to transmit a generated image to the user for viewing. It is better to combine the generated shirt image with the external image. The head-mounted display device includes a housing portion = the optical element is fixed in the housing portion and is shielded by at least two curtains-a shirt image generator to provide high-quality images; the device also includes a removable Women's clothing shielding unit or movable device, and the display screen is converted from a penetrating lens into a display device, and the conversion can be reversed. The device can be mounted on the user's head, while still allowing the user to use traditional glasses' and can be easily separated from the ΗMD, so that the ΗMD can be used alone (for example for watching a movie).

In USP No. 6, 611,385, a wearable display system is proposed. 'The system includes a display panel to display signals processed in a predetermined manner.' The wearable display system includes a light barrier to display the light from the display. Output signals on the panel, an optical waveguide to guide the signal through the grating, an amplifying lens to amplify the signal amplified by the optical waveguide, and display the signal to the user's eyes, and combine with one or more substrates to form an optical waveguide. . According to the wearable display system, the optical waveguide can be adjusted to fit the specifications,

Page 7 1237125 V. Description of the invention (2) and further manufacture and install the optical waveguide individually; therefore, the head-mounted display system is manufactured with minimal time and effort.

In USP No. 5,991,084, a delicate virtual image display system is proposed, which includes a microdisplay, a first magnifying light device including three surfaces, a display input surface, and a reflection / transmission surface. And a reflective first amplifying element surface, and a second amplifying light device. The light of the display target enters the first magnifying light device on the display input surface, and the light propagates in the first magnifying light device, so that the light is projected to an area of the back reflection penetrating surface, at least a part of the surface Within the field of view provided by the second magnifying light device, a reflection / transmission surface corresponding to a first angle of the reflection / transmission surface, so that light is reflected from the reflection / transmission surface and guided to the reflective first Magnifying element surface; the first magnifying element surface reflects light corresponding to the source target, such as an enlarged virtual image, and then the enlarged virtual image is transmitted in the first magnifying light device at a second incident angle corresponding to the reflecting / penetrating surface Return to the reflection / transmission surface, and leave the first amplifying light device via the reflection / transmission surface. A plurality of the second magnifying light devices receives the magnified virtual image from the first magnifying light device, and displays the synthesized magnified virtual image of the magnified virtual image of a source target to a viewer.

In addition, USP No. 6,683,584 suggests a camera display system that displays information via a matrix-type display element mounted on a housing portion and positions the housing portion to correspond to at least one eye of a user; The display is connected to a video or image sensor 'allows the user to see the information or image displayed on the display; the display can be mounted to the housing portion so that the user can move the display' so that the display is in The

1237125 1237125 V. Description of the invention (3) The user's field of view is a special wearable display device in the United States, which includes a viewer, a mirror, a lens, and an image, and then the image is displayed to see the image. Installed on the frame, the living 'so the viewing • However, all the structures to which the image learning technology is proposed because many people have eyes etc.' so it is impossible to clear the image displayed on the head of the viewer, the mirror ' To adjust the image on the retina, but it is not convenient to put it on again, and it is not suitable for head-mounted display images with eye distance. No. 6,680, 802 proposes a monocular field which is delicate and suitable for users to wear, steep pieces; the viewer contains one; L C D, a φ t, and-a microphone. The main lens is introduced to: "dead" so that the user at least 1; brother mouth to a main lens, the elastic element can be wrapped with a microphone device ~ nose bridge to support the elastic element if 1 疋 on the user The predetermined position in front of both eyes. The known technique explained by the escape is shown to the head 6 or the turtle system or machinery to the human eye; see: there was no f 'disease, related structure or mechanism. See clearly in the clear; ^, myopia, amblyopia or strabismus walking away, so when the clear connection is blurred shadow silly / curtain, for the focal length of the eye disease, make ^ deli like myopia The focal length of the normal wearing II image can fall on the user's glasses. Therefore, if you do n’t wear it, you do n’t need to wear it, you need to use the first head-mounted display device to reverse the device. This is necessary-a kind of focus can be adjusted so that the user can see a clear image w 1,禋 The application is to make the function of glasses, especially for wearable display devices to completely take T from weaker ones. I.e.

1237125 V. Description of the invention (4) = Ingest the image, and then process the image in advance to display it on the display screen ::: See the image clearly. However, a head-mounted display device having the above-mentioned function is proposed in all conventional technologies. _ / [Invention description Therefore, the focal length can be adjusted to the display distance. The display system of the present invention, the digital information content storage] The main object of the present invention is to provide a head-mounted display system with digital content display and image adjustment on the display screen of the head-mounted display device for realizing the system Its focus provides a head-mounted content storage and audio signal, and the signal processing digitally includes: a shadow-containing focal length adjustment unit package including a shadow adjuster according to a focal length adjustment signal to generate a focus input image The image system is based on the image signal. The image signal is contained in the whole signal and is connected to the signal processing unit. The unit is mounted on a head-mounted display image, so that the head-mounted display is used to display the adjusted display image. The focal length input generates the focal length adjustment signal to the letter, and provides a focal length value to the focal length adjustment display in the input image display device. The display unit and the connection unit are the single processing unit. The digital display device stores a number for use in the receiving unit. From the digital image, the image is carried out-no sooner than 7L to show the user to the focal distance manual operation unit; the centered The head position information, the image received from the receiver, the focus adjustment content storage adjustment, the display adjustment adjustment, the image adjustment adjustment, the adjustment unit, the focal length wheel, and the number; ; Show a single show to focus on the purpose to produce tm early yuan
