Light conduction is to described polarization splitting prism；
Described polarization splitting prism 104 just to human eye, described quarter wave plate 106 be arranged at described polarization splitting prism away from
The side of human eye, described diopter lens 105 and described quarter wave plate 106 be close to arrange, be arranged at the quarter wave plate side away from human eye,
Diopter lens 105 is provided with a reflectance coating R away from the side of human eye；
Described polarization splitting prism 104 reflects the polarized light of described lamp guide conduction, enters dioptric through quarter wave plate 106
Mirror 105 adjusts, and the polarized light after reflectance coating R reflection adjustment, the polarized light after adjustment is through quarter wave plate 106, polarization splitting prism
104 enter human eye 107.
This utility model provide miniature display system can be arranged in headset equipment, by polarization splitting prism,
Quarter wave plate and the effect of diopter lens, the polarization light sent by display module is incident to human eye after being adjusted, and makes myopia personnel's energy
Enough it is clearly seen that the image that display module is play.Real world images also can be incident to human eye by the first corner cube prism, makes myopia
While personnel can see display module broadcasting image clearly, moreover it is possible to see the image in reality clearly.Separately, in view of quarter wave plate and dioptric
Mirror is arranged at the side away from human eye, it is provided that miniature display system be easier to be combined with headset equipment.
Specifically, the central optical axis of micro-optics system is same direction with the optical axis of human eye.Each optics can lead to
Cross gluing mode to fix.
Described diopter lens is used for myopia correction, and diopter lens can be designed according to the myopic degree of human eye, and reflectance coating is permissible
For part reflective semitransparent film, it is possible to for having the reflectance coating of other reflectance, can be set according to demand, this utility model is to this not
Limit.
Headset equipment described in the utility model includes but not limited to intelligent glasses, intelligent helmet etc., this utility model
Headset equipment is specially and why not limits.
Lamp guide described in the utility model is glass square rod or plastics square rod, as long as light can be conducted and for transparent thing
Matter all can be fabricated to lamp guide described in the utility model.
When being embodied as, anti-reflection film can be set at the lateral wall circumference of lamp guide, for being lowered into the veiling glare of lamp guide, carry
The quality of high display module broadcasting pictures.
Polarization splitting prism of the present utility model includes the first corner cube prism and the second corner cube prism, the first corner cube prism and
Second corner cube prism can be isosceles right-angle prism, it is also possible to for non-isosceles right-angle prism, this utility model is to its concrete structure
Do not limit.The inclined-plane increasing degree of the first corner cube prism or the second corner cube prism has one layer of material with reflectance, forms reflection
Face, is then secured together the inclined-plane of the first corner cube prism and the second corner cube prism by the way of gluing.
In this utility model one embodiment, display module is appointing in LCOS display, OLED display and LCD display
Anticipate one.
When display module is LCOS display, LCOS display does not have active illuminating, needs external light source just can go out
Sending out LCOS display and play image, therefore, miniature display system also includes light source, and described LCOS display is relative with described light source
Arranging, the light that described light source sends exposes to LCOS display, and LCOS display sends polarized light.
When display module is OLED display, the light that OLED display sends does not has polarity, therefore, miniature display
System also includes 1/2 wave plate 110, as in figure 2 it is shown, described 1/2 wave plate is arranged between OLED display and described lamp guide, uses
Polarized light is become in light OLED display sent.When being embodied as, also can be selected for polaroid and replace 1/2 wave plate.
In other embodiments of this utility model, also can be selected for other display modules, according to the characteristic of display module, determine and be
No increase light source and polaroid.
Referring to Fig. 2 again, the miniature display system being applied in headset equipment also includes magnifier 108, is arranged at institute
Stating the diopter lens 105 side away from human eye, described diopter lens is not arranging reflectance coating, and described reflectance coating R is arranged at magnifier
Away from the side of human eye, the polarized light after magnifier effect will form the virtual image amplified after entering human eye, it is simple to observer
The image that display module is play can be clearly seen that.
When being embodied as, in order to make optical system structure compact, magnifier 108 and diopter lens 105 are integrated together formation
One optical lens group.
Further, due in micro-optics system in addition to display module, be all transparent configuration, human eye viewing display
Can be additionally seen extraneous things during the image that module is play, after adding magnifier, the extraneous material object that eye-observation can be made to arrive becomes big, because of
This, in order to warrantor observes observe extraneous in kind indeformable, micro-optics system also includes offset lens 109, fixing connects
Described magnifier, the curvature of the curvature of offset lens and optical lens group (magnifier and diopter lens) matches.
Refer to Fig. 2 again, below as a example by display module is as OLED display, illustrate how observer watches OLED to show
Show the image that device plays.Light communication process is:
Display module 101 emits beam, and after 1/2 wave plate 110, the light of OLED outgoing is converted to S-polarization light, i.e. light
Line 102 is S-polarization light, and S-polarization light is conducted into the polarization light-dividing surface being mapped to polarization splitting prism 104 through lamp guide 103, and this is inclined
The light splitting surface that shakes reflects the S-polarization light conducted by lamp guide, is incident to diopter lens 105 through quarter wave plate 106 and adjusts, then incident
Adjusting to magnifier 108, the side increasing degree away from human eye of magnifier one layer has the reflectance coating R of reflectance, after adjusting
Light reflect, be incident to the polarization light-dividing surface of polarization splitting prism along incident path, now, S-polarization light is through twice
Quarter wave plate effect retrodeviates polarization state and is become P polarization light from S-polarization light, and P polarization light is directed through polarization light-dividing surface, incides observation
In the eyes of person, thus in human eye, form the virtual image clearly amplified；
The light of external image is after offset lens 109 acts on, by magnifier 108, diopter lens 105 and quarter wave plate
The regulation of 106 enters polarization splitting prism 104, and polarization splitting prism 104 makes partial polarized light pass through, incides observer's
In eyes, thus in human eye, form the figure clearly of normal size.
Such as Fig. 3, shown in Fig. 4, this utility model in the specific implementation, in order to reduce processor, makes whole miniature simultaneously
The outward appearance of display system compares suitable system design, and described lamp guide is one-body molded with polarization splitting prism, is formed such as Fig. 3,4 institutes
The prism 303,403 shown, the inclined-plane of this prism 303,403 has been coated with plated film.
This utility model provide miniature display system be easier to be arranged in headset equipment, by arrange lamp guide,
Polarization splitting prism, quarter wave plate, diopter lens and magnifier can make myopia personnel see the image that display module is play, and carry
High Consumer's Experience effect；By arranging offset lens, it is possible to make external image not have exaggerated effect in entering human eye.
The above is merely to illustrate technical solutions of the utility model, and any those of ordinary skill in the art all can not disobey
Carry on the back under spirit and the scope of the present utility model, above-described embodiment is modified and changes.Therefore, right of the present utility model is protected
The scope of protecting should be as the criterion depending on right.
