Abstract

A TV optical system lens is a monomer prism adopting optical resin PMMA material; the shape of both sides of the lens and the right and left central section are prisms close to triangle; the three sides of the triangle represent aspheric arc shape and the three faces of the prism A, B, C are centrifugal aspheric surfaces; the center of the central section is 0 and the positive and negative values are decided by coordinate directions x, y and z; the face A is the measurement eccentricity on y axis and C and B faces are measurement eccentricities on z axis; the eccentricity of the A face is negative 1.12 m with positive and negative difference of 0.1mm; the eccentricity of the face C is positive 1.75 with positive and negative difference of 0.2mm; the eccentricity of the face B is negative 2 with positive and negative difference of 0.28mm. Figures before 0 point are negative and figures behind 0 point are positive; every face is symmetric right and left and asymmetric up and down and before and after.

Description

Head is joined televisor optical system eyeglass

One, technical field:

The utility model relates to the optical system eyeglass that a kind of head is joined televisor, and it can be applied in the terminal display system of electronic product such as head-mounted display, Helmet Mounted Display, personal cinema, wearable computer, mobile phone, 3G mobile and personal equipment.

Two, background technology:

The common feature of this a kind of conventional terminal display system is to have adopted nearly optics of the eye technology, produce similar significantly virtual at a distance coloured image, therefore the image quality of optical system has just become key with the manufacturing difficulty or ease in the display device of the similar glasses of profile, because these traditional optical presentation systems are to adopt multi-disc optical glass combination or multi-disc, monolithic optical resin lens to form, the volume weight that has is bigger, not too welcome, the employing that has eccentric free form surface, design is complicated, the Mould Machining difficulty is very big, and the glossing utmost point cannot say for sure to demonstrate,prove the precision of profile.

Three, summary of the invention:

The purpose of this utility model is to propose a kind of monomer prism that adopts optical resin PMMA material.

Technical solution of the present utility model is: head is joined televisor optical system eyeglass, it is the monomer prism that adopts optical resin PMMA material, eyeglass both sides profile and left and right sides central cross-section all are subtriangular prisms, leg-of-mutton three limits are aspheric surface garden arcuation, three face A, B, C of prism are eccentric aspheric surfaces, the center of central cross-section is O, positive negative value is by x, y, the decision of z coordinate direction, the A face is that tolerance is eccentric on the y axle, C, B face are that tolerance is eccentric on the z axle, wherein A face offset is-1.12mm, positive and negative 0.1mm; C face offset is+1.75mm positive and negative 0.2mm; B face offset is-2.60mm positive and negative 0.28mm.0 in the past for negative, and 0 later on for just; Each profile is a left-right symmetric, and front and back are asymmetric up and down.

Beneficial effect: owing to above reason, the utility model optical system eyeglass adopts optical resin PMMA material through the High Temperature High Pressure high speed injection molding, and it is the monomer prism that design proposal is manufactured that profile adopts eccentric aspheric surface, and design and mold production process are simplified, cycle shortens, and cost reduces.

Four, description of drawings:

Fig. 1 is an OLED organic light emission body minisize display system eyeglass index path

Fig. 2 is that the utility model head is joined televisor optical system eyeglass schematic perspective view

1 is OLED organic luminorphor miniscope among Fig. 1, and 2 is the resin prism.

Five, embodiment:

Its cardinal principle is as Fig. 1: when the Two-dimensional Color Image that is produced by OLED organic luminorphor miniscope 1 is passed the eccentric aspheric curve lens of prism 2 prominent shapes A face, image is amplified for the first time, produce similar distant place effect, the distortion that produces owing to the inclination of miniscope has also obtained correction, when this image that is corrected is injected into the inclination concave surface of eccentric aspheric surface B, by the prism effect of B face reflection and folding, this incline structure can make light path reflect under undamped situation and be folding, when this image reflection when being coated with the C face of metallic reflective coating, being received the eccentric aspheric surface internal reflector of the very little C face of difference amplifies again, when this image of not receiving difference is substantially penetrated the B face by the total reflection film reflection, image is by last amplification again of B face and correction, when arriving onlooker's eyes, the image that the big exit pupil effect of generation is seen the onlooker has been the significantly virtual clearly coloured image far away of a width of cloth number meter.

As can be seen from Figure 2, all subtriangular prism of eyeglass both sides profile and left and right sides central cross-section (among the figure one 2), but and the triangle difference be that leg-of-mutton three limits are aspheric surface garden arcuation, A, B, three faces of C are eccentric aspheric surface.

Owing to be to adopt OLED organic luminorphor miniscope, resolution after image is amplified by prism is the resolution of 800X600, can see the small character and the details of image, resolution than the 320X280 that uses liquid crystal microdisplay LCD has improved many, can reach 1,600,000 looks, because the stereoscopic vision effect of eyes, 3D effect strengthens greatly.But before aspheric surface face type design, must calculate field angle to distance, the size (image height) of virtual image, determine capacity, a fatigue strength of perception human eye in advance according to pupil.When the establishment SECTION EQUATION, looking each profile is lens, at x, revises according to the shrinkage factor of deformation extent and material on the y feed value.In order to save the diamond cutter expense, can on copper material, have a fling at earlier.

C, A, eccentric distance has nothing in common with each other on three faces of B, and A face offset is-1.12mm, and positive and negative 0.1mm, C face offset be+1.75mm, positive and negative 0.2mm, B face offset is-2.60mm positive and negative 0.28mm.

Among Fig. 2, positive negative value is that the center is 0 by x, y, the decision of z coordinate direction, and the A face is the y axle, and C, B face are the z axle, and 0 in the past for negative, and 0 later on for just.Each profile is a left-right symmetric, and (front and back) are asymmetric up and down.

Various surface roughness must reach more than the Rz0.05 micron, and material hardness reaches HRC＞65, otherwise will influence product quality and die life.
