Abstract

The utility model discloses a mini-glasses monitor, which comprises a shell, wherein, a bracket is arranged inside the shell, and the bracket is provided with a micro LCD monitor and a circuit board which is connected with the micro LCD monitor, and an ocular optical element is arranged below the micro LCD monitor, and the ocular optical element is a three-free curved-surface prism, and the free curved surface of the three-free curved-surface prism consists of an incident face 51, a perfect-reflection and exit facet 52 and a reflection face 53. The three-free curved-surface prism is utilized to substitute the non-three-free curved-surface prism to be used as an ocular optical element, so that the volume of the ocular optical element is greatly reduced, and the volume and the weight of the glasses monitor are reduced, and the glass monitor has the advantages of small volume, light weight and thinness. When in use, the view line of the user is free from being blocked, so that the user can observe the surrounding environment, thereby eliminating the safety worry; the user can move at will, so that the glasses monitor is flexible and practical. The weight is light, so that the nose of the user is free from being oppressed by the glasses monitor, thereby having good comfort.

Description

A kind of microminiature glasses display

Technical field

The utility model relates to a kind of display, particularly a kind of microminiature display that uses on the glasses that is installed on.

Background technology

Existing glasses display is fully by the form manufacturing of glasses, as shown in Figure 4, after putting on, people can directly now see video pictures, very convenient, this glasses display has the framed structure of a pair of glasses, comprise housing, the mirror leg, the nose holder, be connected with earphone on the housing, transmission line etc., support is installed in housing, LCD display is installed on the support, the wiring board that is connected with LCD display, the eyepiece optics element is equipped with in the LCD display below, this eyepiece optics element transmission is also amplified the video that LCD display produces, and is sent in user's eye, forms the picture of virtual amplification.The eyepiece optics element that existing glasses display adopts, because of technical factor, volume is of a size of 32 (wide) * 24 (height) * 15 (thick), as shown in Figure 8, owing to the big reason of eyepiece optics component size, the housing of glasses display is also done greatlyyer on volume, volume size is 160 (wide) * 43 (height) * 30 (thick), as shown in Figure 6, owing to above reason, there is following defective in current glasses display: 1, because volume is big, when putting on one's glasses display, block user's sight line fully, caused the user can not observe environment on every side in use simultaneously, caused the user to produce sense of insecurity; 2, owing to blocked sight line fully, the user is arbitrarily shift position, very inconvenience when using this product.3, because glasses display is heavier, reach 70 grams, the user wears when using, and can produce compressing to nose Beam, causes the user to feel uncomfortable; 4, current glasses display only is applicable to that the normal person of eyesight uses, when using this glasses display, myope to take off one's spectacles earlier, the display of wearing glasses again, improper because of diopter, the user can only see fuzzy picture, and at present there is the crowd about sixty percent in the whole world approximately because the shortcoming of eyesight need be worn glasses and could be observed things, thereby the glasses display of now can not satisfy these most people, wears glasses simultaneously and uses the needs of glasses display.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of microminiature glasses display, this glasses display has that volume is little, in light weight, simple structure, characteristics such as easy to use, can see surrounding environment clearly during use, at any time the shift position is fit to twenty-twenty vision crowd and eyesight defectiveness crowd and uses.

The technical scheme that its technical matters that solves the utility model adopts is:

A kind of microminiature glasses display comprises housing, and support is installed in the housing, the wiring board that miniature LCD display is installed on the support and is connected with miniature LCD display, and the eyepiece optics element is installed in miniature LCD display below.It is characterized in that described eyepiece optics element is three free curved surface prisms, form, be respectively the plane of incidence 51, total reflection and exit facet 52, reflecting surface 53 by three free form surfaces.

Wherein, the three free curved surface prism volume sizes that adopt are 14 (wide) * 16 (height) * 8 (thick), as shown in Figure 7, the reflecting surface 53 of described three free form surface eyepiece optics elements is coated with reflectance coating, described miniature LCD display is provided with two, and two miniature LCD display are installed in the support two ends respectively, and described three free form surface eyepiece optics elements correspondingly are provided with two, the shell dimension 90 (wide) * 28 (height) * 18 (thick) of described microminiature glasses display, as shown in Figure 5.

The beneficial effects of the utility model are: eyepiece optics element of the present utility model is three free curved surface prisms, replace traditional non-three free curved surface prisms, significantly reduced the volume and weight of eyepiece optics element, use miniature related accessory simultaneously, correspondingly, the shell dimension of glasses display is also dwindled to greatest extent, deducted simultaneously the mirror leg again, the nose holder, accessories such as earphone, glasses display of the present utility model has had little, gently, thin characteristics, overall dimensions is 90 (wide) * 28 (height) * 18 (thick), general assembly (TW) is less than 26 grams, the utility model can not obstruct the view during use fully because volume size is little, and the user can be when using observes at one's side environment at any time with surplus light, eliminate dangerous psychology, the user is shift position at any time also, and is convenient and practical, and the utility model is because in light weight, can not produce nose Beam to the user during use and produce compressing and can comfortablely use, the utility model directly is clamped on the glasses and uses.Thereby can satisfy the normal needs with abnormal user of diopter simultaneously.
