The present invention relates to a binocular image display device.

Head mounted display devices, head mounted display HMD are widely known. It is a general feature that the image of small displays placed close to the eyes is enlarged with optical elements, so that the virtual image seen by the person wearing the HMD will be distant and wide-angle. HMDs can, in principle, be used for displaying any conventional electronic images, so they can be connected, inter alia, to a video recorder, a computer, a TV, a game console, a video camera, a GPS navigator, and a mobile phone containing them. The optical element used for image magnification may be a lens, a concave mirror, a focusing prism, a mirror, a prism or a semi-permeable mirror for breaking the light path. For example, a device for electronically displaying an image is a liquid crystal display (LCD crystal display), a reflective LCL (liquid crystal on silicon), or an independent light emitting diode (OLE) (organic light emitting diode). The image displayed may be monocular (one image with one eye), biocular (one image with two eyes), and binocular (different images for the two eyes, if they are the same, the image is monoscopic if the same from two different angles, the image is stereoscopic) .

Apparatus attached to the head for attaching to the head (such as the apparatus according to Fig. 1 of US D556,815 or US Patent No. D513,031) is attached to the head by clamping the two sides of the head and leaning behind the ear, as well as a support arm. They usually contain a pre-eye box that includes the microdisplay control electronics in addition to the two microdisplays and optical systems that display the image, and as it is located in front of the eyes, it covers the view at the eye level, partially obstructing the outside world. The wearer does not see the vehicles coming into the eye, the face of the standing / standing persons, the device is somewhat "blind" and makes his wearer vulnerable. This narrows its scope, for example, when traveling on public transport - which would otherwise be a very important field of application because traveling is a "dead time" for most people - not to use.

In order to reduce weight and create a freer field of vision, HMDs have been developed where only one viewer is present. However, looking at this image, the other eye sees something quite different in the same direction (external environment), which is extremely distracting. In order to eliminate it, the wearer is squinting with half-eyes, which is tiring.

In addition to both visible images, the devices according to U.S. Pat. Nos. 5,129, 716 and 5,682,173 provide a more open field of view, with the last mirror projecting the image into the eyes with transparent fasteners attached to the eyeglass-like frame so that it can be seen in all directions around said element. The other elements of the image display system and their covers, however, hang into the field of view, and this frustrates the unobstructed view.

The object of the present invention is to eliminate the above-mentioned defects, shortcomings, and to create a lightweight device providing a wide-angle virtual image for both eyes, in which the entire field of vision remains free of the virtual image displayed in the lower part of the field of view.

For a large angle of view that can be achieved with a simple optical system, it is advisable to place the microdisplay close to the eyes, using a binocular system, ie a separate image display block per eye. The optical system contained therein can be known per se as a combination of a lupe (multi-lens lens system for reducing imaging errors) or a semi-permeable mirror and a concealed mirror, a light emitting or illuminating microdisplay that preferably includes a control circuit to avoid too much cable extension. it must accept video signals and power supply, and all these elements are surrounded by a cover window with a viewing window on the exit beam side.

Interpupillary distance for all types of IPDs commonly used in known video glasses - an appropriate high-output pupil-exit pupil - focuses on a particular wearer with a much wider angle of view than needed and because only a portion of the pre-focusing element serves to display the image , the others obscure the view unnecessarily. At a given magnification, the focusing area of the said focusing element is the smallest field of view when its aperture is as large as the cross-section of the light beam at the spot from the screen to the eye, and when placed in front of the pupil, the virtual image fills the viewing angle occupied by the focusing element. In order to expose the wearer in all directions, the other elements of the image display block must also be positioned in the direction or in the cover of the focusing element, in which case the thin cover surrounds the focusing element, the microdisplay, and the control circuit as a dark edge with blurred edges. appears on the sharp, contrasting virtual image and forms part of the sight.

The invention is based on the discovery that a completely free field of view around the described image display blocks can be achieved if they are attached to the head by a transparent, visible refractive bracket and adjusting elements.

The essence of the invention is that the eyeglass-mounted bracket is a pre-eye bridge with a transparent rigid disc having two parallel faces of two parallel members, slidably attached to the eye as a constrained path along the plate, in the lower part of the field of view from the eye, in the lower part of the field of view. placed two image display blocks.

In a possible embodiment of the invention, the bracket of the bracket is a thick planar plate strip bounded by the peripheral planes cut from the top and bottom by the planes of the straight line passing through the center of the eyeballs, preferably through the center of the eyeballs. The importance of oblique border surfaces is that they can be seen on the edge of the pupil's eye, so they do not obscure the visual field, and on the other hand they are not able to reflect the external light in the eye. The bridge is freely separated from the three sides by the face-to-face slider, consisting of a transparent slab element, the lower part of which includes a support plate extending in the opposite direction to the eyeball. The image display block is attached to the lower surface of this support plate with an eye window facing the eyeball. The central part of the bridge is provided with a nose support, the easiest way of which is a cut-out that fits the average shape of the coat. The two ends of the bridge continue to be thinner and narrower, such as flexible transverse stems with small cross-sections that can be clamped onto the wearer's head.

The figures used to describe the invention in detail show:

Fig. 1 is a side view of a binocular image display device according to the invention during wear;

Figure 2 is a perspective view of the device of Figure 1

Figure 3 is a fragmentary side view of the device of Figure 1 showing the eyeball and multiple pupil positions

Figure 4 is a top plan view of the device of Figure 1;

Figure 1 shows that a person having a device according to the invention has a support frame 2 made of a transparent plate, such as a clear polycarbonate, on the head of the device 1, which is the head 1 of the planar parallel plate 4 and behind the ears 5a, 5b. consists of two slightly squeezed, small cross-sectional elastic stems 6a, 6b on both sides. Slides 7a, 7b made of transparent sheet are connected to the bridge 4 for which optical • β •

adhesive transparent support plates 8a, 8b are fastened to their lower parts, which are broken in obtuse angles, with viewing windows 15a, 15b facing the image display blocks 9a, 9b, eyes 3a, 3b.

As shown in Figure 2, the topsheet 10a, 10b of the sliders 7a, 7b lie on the upper edge surface 11 of the bridge 4, the lower face 12a, 12b of the lower edge surface 13a, 13b of the non-visible portion thereof,

The connecting plate 31a and 31b is on the opposite side of the bridge 4 and, in the case of a suitable fit, without slipping but easily slipping on it. To avoid scratching, a spacer gap may be provided with a slightly smaller thickness of the middle portion of the connecting plates 31a, 31b. The relatively large size of the slider provides accurate guidance for moving the image display blocks 9a, 9b, which is important because the virtual images seen by the left and right eyes remain exactly overlapping while being dragged. Bonding the support plate 8a, 8b on a large surface is important because of the strength of the image display blocks 9a, 9b that are caught in the console. The motion range of the image display blocks 9a, 9b is limited by the stop members 14a ', 14a', 14b ', 14b on the top edge surface 11, which can of course be formed on the lower edge surfaces 13a, 13b.

Referring to FIG. 3, the image display block 9b comprises a microdisplay 17b, a microdisplay control circuit 18b, a semi-permeable mirror 19b, and a concave mirror 20b in an envelope 21b surrounding it, having a viewing window 15b on the front panel 22b of the eye 3b. When adjusted with the slider 7b, the light beam 24b extending perpendicular to the center of the screen 23b of the microdisplay 17b and passing through the optical elements moves toward the center 27b of the eyeball 26b through the respective pupil 25b. The figure shows that if the plane of the upper edge surface 11 of the bridge 4 passes obliquely, preferably through the center 27b of the eyeball 26b, this surface is visible to the pupil 28b of the turning eye 3b and thus cannot reflect external interfering lights. 29b for retina. The top end 10b of the top plate 10b of the slider 7b on this upper edge surface 11b is only a narrow strip whose image is close to the eye 3b and the resulting pupil 28b is much larger (anthropologically about 4 mm on average) due to its diameter, the 29b retina is completely blurred. Ultimately, the visual field obscuration is vertically scanned as follows: the eye 3b freely looks over the top plate 10b, the top panel 10b is blurred, the overlapping transparent bridge 4, the connecting plate 31b, and the retaining plate 8b can be seen without distortion. in the viewing window the virtual image itself appears, under the cover 22a, 22b the view is free, the cover is practically closed

It is a frame-like front panel 22b that appears as a blurry dark border around the sharp, contrasting virtual image and forms part of the sight.

As shown in Figure 4, the bridge 4 and the shafts 6a, 6b are formed in one member, the upper edge of the dA of the bridge H continues at the upper part of the narrower stems 6a, 6b, so that for eye 3a, 3b this is also seen in the edge. not visible. The step 32b of the thickness transition between the bridge 4 and the shafts 6a, 6b is flush with a plane passing through the center 27b of the eyeball 26b, which is expected to be in the average IPD, so that it can be seen at the edge of the eye 33b having a pupil 33b. Similarly, this is true for the symmetrical side. From the microdisplay control circuits 18a, 18b not shown here, the electric cable 34 leads to a source of power and video signal, such as an MP4 player, a PDA, a TV tuner, a game console, a video camera, a GPS navigator, a mobile phone. For example, if a voice is required, it can be routed to the tabs 5a, 5b via a branch of the electric cable 34 not shown here.

Functionally, the support frame 2 of the binocular image display system according to the present invention can be worn in a spectacular manner, with the orbital support 35 on the head 1, and the head 1 with clips 6a, 6b clamped on both sides, wearing glasses over their own vision correction glasses. The bridge 4 is so rigid that the stems 6a, 6b do not bend evenly so as to cause optically disruption, the virtual images seen with the left and right eyes slid apart.

To start using, the device must first be connected to the source of the power and video signal, and precisely the pupil blocks 9a and 9b must be placed in front of the pupils. To do this, one has to move the sight windows 22a, 22b horizontally in front of the eyes 3a, 3b with the help of the sliders 7a, 7b, and then, by lifting or lowering the ends of the stems 6a, 6b, which are attached to the side of the head, vertically, the center of the virtual image is 22a, 22b in the middle of the viewing window. This can be done with adjustable ·>

Height 35 is also provided with a knife support. The appearing sight is preferably dark 22a,

22b, large, high-resolution, far-sighted, bright, contrasting video image with a full view, clear field of vision, caused by a blurry dark frame around the 22a, 22b front window. The virtual picture and its narrow dark frame overlaps what is behind it, but since this cover is in the lower middle of the field of view, the least disturbance is in the orientation, as the picture can be viewed as conveniently as possible in the usual desktop reading angle, while walking dropping on the ground, driving a car • «· • · ·

6/9 appears in and around the dashboard, on a long-distance bus, sitting on an airplane, facing the back of the previous seat.

The invention can be used by students, young people, for example, to watch films, entertain, watch TV while traveling, people waiting; doctors can see the area at the optimum angle for laparoscopic surgeries while observing the assistance and instruments in a circle; security guards, soldiers, policemen, firefighters constantly see their visual information, etc., in their field of vision, etc.
