Description
Technical field
This utility model relates to intelligent terminal's technical field, more particularly, it relates to a kind of head-mounted display。
Background technology
Along with electronic device constantly develops to ultraminiaturization, and the development of new computer, microelectronics, photoelectric device and communication theory and technology, this new ant algorithms based on " people-oriented " " people computer system " of wearable computing has become as possibility。Application is continued to bring out in fields such as military affairs, industry, medical treatment, education, consumption。In a typical wearable computing system architecture, head-mounted display apparatus is crucial ingredient。Head-wearing display device passes through optical technology, by miniature image display (such as transmission-type or Reflective liquid crystal displays screen, organic electroluminescence device, DMD device) video image light that sends is directed to the pupil of user, nearly order scope at user realizes virtual, enlarged drawing picture, provides directly perceived, visual image, video, Word message for user。
For reaching better display effect, when user wears head-mounted display, need eyes and face near the eyes are close to head-mounted display, cause that some users having defective vision cannot use glasses while using head-mounted display, the picture that so they see also can be fuzzyyer, largely effects on experience。
A kind of disclosed in prior art can the goggle structure of accurate regulating diopter, the wherein eyepiece mount by adopting eyepiece stalk to be connected through multiple thread with eyepiece stalk, and it is sheathed on adapter ring after the eyepiece mount on eyepiece mount, it is embedded at the eyepiece group in eyepiece mount, if slotted Non-return ring, and the structure such as locating slot, locating ball。Although adopting which can realize the accurate adjustment of goggle structure diopter, but it being it is not disclosed how when having bilateral eyepiece, match this diopter adjustment structure with other structures the adjustment realized bilateral width between eyepiece, and namely interpupillary distance regulates。
A kind of head-mounted display disclosed in another prior art, wherein adopts X-axis support and Y-axis support to achieve the adjustment to head-mounted display diopter and interpupillary distance so that it is to adapt to the user of different eyesight status。In the program, need drive two lens barrels to slide along X-direction on X-axis support simultaneously and then the center distance of two lens can be adjusted, to adapt to the user of different interpupillary distance, Y-axis adjusting part is used for driving X-axis support along the relative Y-axis bracket slide of Y direction and then to adjust two lens and display floater fore-and-aft clearance。
A kind of adjustable head-worn display disclosed in another prior art, in the program, main body frame is provided with the Diopter accommodation assembly of the spacing individually regulating every forward and backward lens barrel of side mirror group, realize interpupillary distance also by interpupillary distance adjusting part to regulate, when interpupillary distance regulates rotating disk rotation, drive two driving members synchronously to move left and right by central gear, regulate the distance between the front lens barrel of two side mirror groups, it is achieved the interpupillary distance of head-mounted display regulates。
Above-mentioned second and third program all can realize the adjustment to diopter (diopter) and interpupillary distance simultaneously, but need to drive bilateral lens or lens barrel to move the adjustment realizing interpupillary distance simultaneously, not only structure is complicated, volume is bigger, and due to only one of which display screen, when interpupillary distance regulates, can there is relative movement with bilateral lens or lens barrel in the effectively display picture of display screen, cause optical center and display centre dislocation, directly affect the display effect of edge picture；Simultaneously, in diopter adjustment process, mobile lens or lens barrel can change the distance between lens or lens barrel and display screen simultaneously, and change human eye to the distance between lens or lens barrel, namely change and connect eye-distance, and the change connecing eye-distance can make diopter degree of regulation reduce, cause that viewing effect is deteriorated。
Further, since at present head-mounted display be towards volume compact, lightweight, be easy to wear, alleviate the directions such as load and develop, complicated structure inevitably results in that head-mounted display small product size increases, weight increases, thus affecting the result of use of head-mounted display。
