20110310491 | VIRTUAL IMAGE DISPLAY DEVICE AND LIGHT GUIDE PLATE THEREFOR - The image light entering the image take-out section is reflected by the first reflecting surface and the second reflecting surface in a two-stage manner. It is not only possible to make the light beam with a small total reflection angle out of the image light directly enter the side near to the light entrance section out of each of the reflecting units, but also to make the light beam with a large total reflection angle directly enter the side far from the light entrance section out of each of the reflecting units to thereby make it possible to take out the image light to the outside. Therefore, the image light is emitted as the effective virtual image light for the observer in the condition in which the brightness variation and the picture variation are prevented and a high light efficiency can be obtained. | 12-22-2011 |
20120057253 | LIGHT GUIDE PLATE AND VIRTUAL IMAGE DISPLAY APPARATUS HAVING THE SAME - Since a distance from an image extraction part to a light exiting surface is shorter downstream in an optical path than upstream in the optical path in relation to Z direction that is an arraying direction of reflection units, image light that propagates to pass between the image extraction part and the light exiting surface without becoming incident on the reflection units and therefore cannot be extracted to outside can be reduced. That is, since image light having a large total reflection angle in a light guide plate can be securely made incident on the image extraction part and efficiently extracted from the light exiting surface, light use efficiency in image formation can be enhanced. Thus, a virtual image display apparatus with brightness and high performance can be provided. | 03-08-2012 |
20120086623 | VIRTUAL IMAGE DISPLAY APPARATUS - An advantage of some aspects of the invention is to provide a virtual image display apparatus in which occurrence of luminance spots is suppressed to improve efficiency of use of illumination light. In the virtual image display apparatus of the invention, an optical-directivity changing section forms a non-uniform distribution concerning the directivity of image lights GL emitted from an image display device. Therefore, even when an angle of a light beam emitted from the image display device and effectively captured into the eye EY of an observer is substantially different depending on a position of the image display device, it is possible to form the image lights GL having directivity corresponding to such an angle characteristic of light beam capturing. It is possible to suppress occurrence of luminance spots to improve efficiency of use of illumination light. | 04-12-2012 |
20120086625 | VIRTUAL IMAGE DISPLAY DEVICE - The invention is directed to provide a virtual image display device capable of setting the aspect ratio of the image light entering the eyes of the observer as a virtual image to a desired state while fulfilling the design limitations. In the invention, the aspect ratio of the virtual image can be converted to the aspect ratio (16:9) laterally longer than the aspect ratio (4:3) of the image area due to the conversion in the aspect ratio conversion optical system. Thus, the aspect ratio of the image light to be recognized by the eye of the observer as a virtual image can be adjusted to a desired state even in the case in which, for example, the lateral width of the image forming device with respect to the whole of the virtual image display device is limited by a design requirement. | 04-12-2012 |
20120098734 | LIGHT GUIDE PLATE AND VIRTUAL IMAGE DISPLAY DEVICE EQUIPPED WITH THE SAME - The sizes of the respective reflecting units vary in the image take-out section along the Z direction in association with the state of the total reflection angle in the light guide section. Thus, it becomes possible to keep the sufficient effective light beam width of the image light input thereto in all of the reflecting units. Therefore, the deterioration in the image light caused by the reflection in the reflecting units can be avoided, and as a result, the degradation of the resolution of the image due to the virtual image light thus emitted can be prevented. | 04-26-2012 |
20120200935 | VIRTUAL IMAGE DISPLAY APPARATUS - A support frame includes a light transmissive portion that is combined with a light guide member to form a see-through portion. The support frame assembled with the light guide member for image light observation therefore allows see-through observation of an outside-world object through the see-through portion. Further, providing the light transmissive portion in the support frame can increase the strength of the support frame while reducing the weight of the light guide member. | 08-09-2012 |
20120200936 | VIRTUAL IMAGE DISPLAY DEVICE - In regard to a second direction (combination direction) that is turned back by a reflection at the time of light-guiding, a projective optical system has an emission opening width larger than an opening width of a third reflective surface, such that it is possible to prevent a partial deficiency of image light when the image light emitted from the projective optical system is incident to the third reflective surface from occurring, and thereby it is possible to prevent the occurrence of deficiency of an image or a large variation in brightness. | 08-09-2012 |
20120200937 | VIRTUAL IMAGE DISPLAY DEVICE - A half mirror layer has an angle dependency in which when an angle of incidence becomes larger than the angle of incidence range of image light, reflectance increases, such that it is possible to prevent unintended light, which is emitted to a light transmitting member from a light guiding member and is reflected inside a light transmitting member, from being returned to a light emission portion of the light guiding member after passing through the half mirror layer as a reflective film at a relatively large angle of incidence. Therefore, it is possible to prevent the image light passed through the light transmitting member from becoming ghost light while mitigating the demand for increasing processing accuracy of the light transmitting member, and bonding accuracy between the light guiding member and the light transmitting member. | 08-09-2012 |
20120200938 | VIRTUAL IMAGE DISPLAY DEVICE - Image light reflected by a third reflective surface of a light incidence portion is propagated while being totally reflected by first and second reflective surfaces of a light guiding portion, is reflected by a fourth reflective surface of a light emission portion, and is incident to observer's eye as a virtual image. At this time, the number of times of reflection of first image light, which is emitted from a first partial region of an image display device, in the light guiding portion, and the number of times of reflection of second image light, which is emitted from a second partial region of the image display device in the light guiding portion are different from each other, such that it is possible to take in the image light beams from the different partial regions of the image display device with a relatively wide angle of view. | 08-09-2012 |
20120206817 | VIRTUAL IMAGE DISPLAY SYSTEM - A thickness of a tapered part provided at the deeper side (−X side) in a light guide direction of a light transmission member is smaller toward the deeper side, and thus, a reflection angle of ghost light that has passed through a fourth reflection surface provided with a half mirror layer and reached the light transmission member gradually becomes smaller within the tapered part and no longer satisfies a total reflection condition, and the light is ejected to the outside in the position diverging from an eye of an observer. That is, the tapered part may prevent the ghost light from reaching the eye and good see-through observation can be realized. | 08-16-2012 |
20120243102 | IMAGE RELAY OPTICAL SYSTEM AND VIRTUAL IMAGE DISPLAY DEVICE INCLUDING THE SAME - An image relay optical system is provided with an optical coupling member before incidence of image light on a light guide member. Among a first light incident surface, a coupling member reflecting surface, and a first light emitting surface provided in the optical coupling member, the coupling member reflecting surface and the first light emitting surface are curved surfaces. Therefore, a large bright virtual image with reduced aberration can be displayed. | 09-27-2012 |
20130070344 | VIRTUAL IMAGE DISPLAY DEVICE AND MANUFACTURING METHOD OF VIRTUAL IMAGE DISPLAY DEVICE - In fabrication of a light guiding unit, a half mirror layer as a reflection film for folding light is covered by a light transmission main body part as a coating member, i.e., a light transmission member, and a hard coating layer is deposited thereon. Therefore, even when the surfaces of a light guide main body part and the light transmission main body part forming the light guiding unit are cleansed as pre-processing of the deposition of the hard coating layer, the situations such that the half mirror layer is separated thereby may be avoided and optical properties of the half mirror layer may not be lost. | 03-21-2013 |
20130083403 | VIRTUAL IMAGE DISPLAY DEVICE AND METHOD OF MANUFACTURING THE SAME - In a virtual image display device, a mirror layer has a thickness of 50 nm or more to perform non-transparent reflection in a second ridge line vicinity area on a third reflection face side in a ridge line portion extending between the third reflection face and a second reflection face. Accordingly, reflectance of image light can be prevented from being decreased by the second ridge line vicinity area (that is, a peripheral portion on a light guide unit in the third reflection face), and thus stripe-shaped brightness unevenness extending in a longitudinal direction can be prevented from occurring on the viewed image. That is, in the image display device, it is possible to secure sufficient reflection even in the peripheral portion close to a boundary with the second reflection face with respect to the third reflection face, and also to display a bright image with little brightness unevenness. | 04-04-2013 |
20130083404 | VIRTUAL IMAGE DISPLAY DEVICE - A virtual image display device has a light guide device in which the half mirror layer (the semi-transmissive reflecting film) of the light guide member is formed on the partial area of the first junction surface, and the second junction surface of the light transmitting member is bonded to the first junction surface in at least the exceptional area. Therefore, it is possible to increase the bonding strength of the first junction surface and the second junction surface, namely the strength of the light guide device composed of the light guide member and the light transmitting member combined with each other even in the case in which the attachment force of the half mirror layer (the semi-transmissive reflecting film) with respect to the first junction surface is not sufficiently strong. | 04-04-2013 |
20130088415 | VIRTUAL IMAGE DISPLAY DEVICE AND MANUFACTURING METHOD OF VIRTUAL IMAGE DISPLAY DEVICE - In a virtual image display device, direction adjustment of an image optical axis, i.e., angle adjustment of a direction of eyes of an observer can be performed by providing a cushion member or adjusting an amount of shift between an image display unit and a projection system, and thereby, strain on eyes of an observer in use may be reduced. Even when the virtual image display device is used over a long period, for example, stress on the observer may be suppressed. | 04-11-2013 |
20130222214 | VIRTUAL IMAGE DISPLAY DEVICE - A light emitting device, which is a main body, is arranged to be located closer to the nose NS side than the eye EY of a wearer during wearing of a virtual image display device. Therefore, the light emitting device is prevented from excessively projecting to the side of the face of the wearer. The light emitting device is arranged between the eye EY of the wearer and the virtual-image forming member. Therefore, the light emitting device is prevented from excessively projecting further to the front side than the virtual image forming member, i.e., the front side of the face of the wearer. Further, a combined-light forming unit is a unit small in size and light in weight. Therefore, it is possible to suppress the center of gravity of the entire virtual image forming member from deviating to the side and the front side. | 08-29-2013 |
20130222896 | VIRTUAL IMAGE DISPLAY APPARATUS - An intermediate image is formed inside a prism by a projection lens and the like. Image light, totally reflected, in the order of a third surface, a first surface and a second surface, on two or more surfaces thereof, reaches an eye of an observer after passing through the first surface. Thus, it is possible to decrease the thickness of the prism and to reduce the size and weight of the entire optical system. Further, it is possible to realize a bright high-performance display with a wide viewing angle. With respect to external light, it is possible to pass the external light through the first surface and the third surface, for example, for observation. Further, by setting diopter at this time to about 0, it is possible to reduce defocusing or warp of the external light when the external light is observed in a see-through manner. | 08-29-2013 |
20130222919 | VIRTUAL IMAGE DISPLAY APPARATUS - An intermediate image is formed inside a first prism, and an image light, which is reflected on the order of a third surface, a first surface and a second surface, is transmitted through the first surface and reaches the eyes of the observer, therefore it is possible to make the entire optical system small and light in weight by making the first prism thin, and realize a high performance display device with a wide angle of view. Further, when an external light is passed through, for example, the first surface and the third surface and observed, a diopter scale is set to approximately zero, and thereby reducing the defocus or distortion of the external light when observed in a see-through manner. And, it is possible such that the shape of the first prism conforms to the face of the observer, the center is also close to the face. | 08-29-2013 |
20130234915 | VIRTUAL IMAGE DISPLAY APPARATUS - A wearer of a virtual image display apparatus can adjust the position of the virtual image display apparatus relative to the position of each of the wearer's eyes by using a registration mechanism while checking a marker member that is a positioning member, whereby an optimum adjusted position is readily achieved. Further, registration according to person-to-person differences in the position of each of the eyes can be readily achieved, whereby it is not necessary to increase the light flux width of image light in advance or provide the image light with a margin so that the wearer can recognize an image even when the position of the eye deviates from a normal position to some extent, and the size of the apparatus will not increase. | 09-12-2013 |
20130235440 | VIRTUAL IMAGE DISPLAY DEVICE - Image lights formed by a light emitting device and a virtual-image forming member and external light transmitted through a visibility adjusting member and the virtual-image forming member can be observed in parallel in a see-through manner. In the observation of the external light, the visibility adjusting member enables visibility adjustment corresponding to the eyesight of a wearer. Therefore, the wearer can observe the external light without wearing a device for visibility adjustment such as glasses. Therefore, it is possible to suppress an increase in the size of a virtual image display device. | 09-12-2013 |
20130278497 | VIRTUAL IMAGE DISPLAY APPARATUS - An attitude information detection unit detects the attitude of a wearer, and an arithmetic processing unit and a device position drive unit, which form an image area position adjustment mechanism, translate a liquid crystal display device that is a light modulating device relative to a light guide section in a plane parallel to a light incident surface of the light guide section based on a detection result from the attitude information detection unit, whereby the position of an image area can be so changed that an image moves in the direction opposite the direction in which the wearer moves. As a result, when the wearer moves, the image does not follow the motion of the wearer as if the image remained still, whereby the wearer who moves will have a reduced amount of unpleasant sensation resulting from the motion. | 10-24-2013 |
20130335828 | VIRTUAL IMAGE DISPLAY DEVICE - A half mirror layer has an angle dependency in which when an angle of incidence becomes larger than the angle of incidence range of image light, reflectance increases, such that it is possible to prevent unintended light, which is emitted to a light transmitting member from a light guiding member and is reflected inside a light transmitting member, from being returned to a light emission portion of the light guiding member after passing through the half mirror layer as a reflective film at a relatively large angle of incidence. Therefore, it is possible to prevent the image light passed through the light transmitting member from becoming ghost light while mitigating the demand for increasing processing accuracy of the light transmitting member, and bonding accuracy between the light guiding member and the light transmitting member, and thereby it is possible to make a virtual image displayed by a virtual image display device have a high quality. | 12-19-2013 |
20140049833 | VIRTUAL IMAGE DISPLAY APPARATUS - A light blocking member that is a light blocking structure disposed in an exit pupil position can remove in advance a light component of video image light that undergoes unintended reflection to avoid generation of ghost light and allows formation of a satisfactory image. Further, a projection lens and other components form an intermediate image in a prism, and the video image light totally reflected off at least two surfaces of the prism, a third surface, a first surface, and a second surface in this order, passes through the first surface and reaches an eye of a viewer, whereby the prism can be thin and the overall optical system can be compact and lightweight and provide wide angle, bright, high-performance display. | 02-20-2014 |
20140139404 | VIRTUAL IMAGE DISPLAY APPARATUS - Image light is formed of light flux components having a diameter of, e.g., 3 mm or smaller. The image light is then caused to be incident on the iris of an eye to form an image in the form of a virtual image. The position where the principal rays of the light flux components that form the image light intersect one another is set to be a position shifted from the position of the iris of the eye toward the retina. The range of the light flux components that reach the retina can thus be changed in accordance with the motion of the eye. As a result, in accordance with a change in the line of sight that occurs when a wearer moves the line of sight in a specific direction, the image light can be so controlled that only image light components in the specific direction reach the retina of the eye. | 05-22-2014 |
20140139553 | VIRTUAL IMAGE DISPLAY APPARATUS - A trapezoidal correction processing portion performs trapezoidal correction (distortion correction) on video image areas each of which is divided into a plurality of video image areas separately in accordance with the divided video image areas.
