Description

Perspective near-eye optical display

The present invention relates to an augmented reality system that utilizes a transparent or translucent see-through near-eye display optically aligned with a microlens array. The transparent or semi-transparent see-through display must allow light from a distant world to pass through and through the microlens array. The light from the display passes through the microlens array, then through a spectacle lens that provides refractive correction for the specific gaze direction, and then enters the pupil of the eye. In a static embodiment where the microlenses are static, light from the real world passes through the transparent or translucent part of the display and the microlens array, and then is incident on the spectacle lens to form a real image. The quality of the virtual image can be influenced by many factors, such as by way of example only, the aberration of the microlenses in the microlens array, the number of bright pixels generating the virtual image, the brightness of the pixels generating the virtual image, and/or the The enlargement of the image produced by the AR system. Therefore, there is always a need to improve the quality of virtual images. In a dynamic embodiment, the microlens and/or microlens array can be switched between two optical powers (by way of example only, no optical power or optical power) in order to provide an optimal combination of a virtual image and a real image (As a result of augmented reality). In certain situations, the quality of real images and the quality of virtual images will affect the quality of augmented reality as perceived by the eyes of a user. In certain dynamic embodiments, the switchable microlens array is electrically connected to the see-through near-eye display. Therefore, it is necessary to use enhanced design techniques to enhance virtual images, such as by incorporating these techniques into the design of near-eye displays and microlens arrays.

Today's augmented and/or mixed reality systems have a large form factor in most cases and are bulky, heavy, power consuming, limited in type and expensive. In order for these systems to have increased adoption, an important transformation technology change is required. The innovations revealed in this article teach this breakthrough in AR (Augmented Reality) and MR (Mixed Reality) eye-mounted/head-mounted systems.

According to an embodiment of the present invention, the present invention is an augmented reality system that utilizes a near-eye see-through optical module that includes a transparent or translucent see-through near-eye display optically aligned with a microlens array. According to a particular embodiment of the present invention, the augmented reality system includes generating a space in the real world with a position in the real world that is formed by an eye of a wearer of the augmented reality system looking at a real image Perceive a virtual image when an object. When using a particular embodiment of the present invention, by way of example only, the virtual image is attributed to the eye or both eyes due to changing the position of the different light-emitting pixels of the (etc.) see-through near-eye display (such as ) The fixed position shifts to change one or more of its shape, form, depth, 3D effect, position. It is important to note the following, unlike other AR systems where “first” an eye tracker locates the eye of a wearer and then illuminates (lights) appropriate pixels for this position of the eye of a wearer, in In the aspect, the opposite occurs in this embodiment. "First" illuminates (lights up) one pixel or a plurality of pixels and the fixed point of the eye(s) moves to see the bright pixel or the bright pixels. Therefore, the eye or both eyes are one of the followers of the near-eye display. The invention further discloses various ways to improve the quality of the virtual image and the quality of the augmented reality image while using a near-eye perspective optical module including a see-through near-eye display and a distance-aligned and aligned microlens array. An embodiment for producing this improvement can be used for the inventive near-eye fluoroscopy optical module with or without an eye tracker.

Reference will now be made in detail to various exemplary embodiments of the invention. It should be understood that the following discussion of the exemplary embodiments is not intended to be a limitation of the present invention. In fact, the following discussion is provided to give the reader a more detailed understanding of one of the specific aspects and features of the present invention.

According to the embodiments, the present invention teaches various ways to improve the quality of the AR image provided by the perspective near-eye optical module of the present invention described herein. The invention relates to a see-through near-eye display, which is optically aligned with a microlens array. The see-through near-eye display allows light from a distant world to pass through and through the microlens array. The light from the display passes through the microlens array, then by providing a spectacle optic with refractive correction for the specific gaze direction, and then enters the pupil of the eye without forming an image.

Referring to the figure, as shown in FIGS. 1 to 4, the resolution of the virtual image formed on the retina can be improved by dithering the small lenses (microlenses) of the microlens array in the x and y planes. The layout of pixels or pixel tiles can be dithered. In addition, MLA (Microlens Array) can also be dithered; in other words, its x and y position changes by an amount less than its equal pitch. The dithering of pixels or pixel tiles can improve the quality of virtual images. The dithering of pixels or pixel blocks can be dithered within the range of 5% to 20% of the pitch. The dithering of lenslets/microlenses can further improve the quality of virtual images. The dichroism of the small lens/microlens can be within the range of 5% and 50% of its equal pitch, such as from 5% to 10%, 10% to 15%, 15% to 20%, etc.

In an embodiment, the pixel-wise image group that makes the dithering shift or another term partially offset (misaligned) is specifically designed for the purpose of improving the overall performance. The increased resolution is achieved by producing a slight shift on the retina of the overlapping images generated by the plurality of pixel tiles. This can be achieved by shifting the position of the pixel block or MLA (microlens array) lenslet (microlens). Dithering can be applied when light is collected from multiple small lenses (microlenses) or optical channels simultaneously and accepted through the pupil of the eye. The configuration may be such that multiple pixel tiles cause their equivalent light to be imaged in or on a common retinal area.

Dithering can be used with a pixel array of a populated near-eye display to increase the resolution of virtual images. Dithering can be provided by slightly modifying the pitch of small lenses (microlenses of an MLA). Dithering can be provided by slightly modifying the pitch of pixels or pixel tiles of a near-eye display.

According to an embodiment, the invention taught herein describes an augmented reality system, wherein the augmented reality system includes a microlens array and a see-through near-eye display, where the real image is substantially unchanged from the real world (meaning Not refracted by the microlens) formed by the light seen by the near-eye display and through the microlens array and is seen by one of the eyes of a user, wherein the virtual image is used by the microlens generated by seeing through the near-eye display through a microlens array The light seen by the eyes of the author is formed and the dichromaticity is seen through the pixels or pixel tiles of the near-eye display or the microlenses of the microlens array. Pixels can be colored within the range of 5% to 50% of their equal pitch. Pixel tiles can be colored in the range of 5% to 20% of their equal pitch. The microlens can transfer color within the range of 5% to 50% of its equal pitch. The augmented reality system may include dithered pixels or pixel tiles and microlenses of the microlens array. By dithering pixels, pixel tiles, microlenses, or any combination thereof, it can be enhanced as a virtual image seen by the eyes of a user of an AR system.

The invention utilizes the eyes of one of the followers who see through the near-eye display. In the aspect, the eyes are not moved first to see the additional details of a virtual image, but the lighting from the display is changed to drive the eyes to see a changed virtual image. With the present invention, the macula and/or the central fossa are completely or partially filled with virtual images. With the present invention, in order to see one of the changes in the virtual image, the display can display different contents or image forms that completely or partially fill the macular and/or central fossa of the eyes of the augmented reality. In the aspect, the eyes do not "move" to see a different tile-shaped area of one of the virtual images displayed by the near-eye display. In fact, with the present invention, the macula and/or the central fossa are completely or partially filled with virtual images to see more details or a different part of a virtual image. In the aspect, the content displayed can be changed, but the eyes can remain mostly or partially or completely stable, except for involuntary eye movements. In an embodiment, a plurality of pixel tiles produce a partially or completely overlapping retinal image, thus increasing the brightness and increasing the contrast of the virtual image. In the aspect, the display (specifically, the activation pixel in the display at any point in time) can control the gaze direction and change the real image corresponding to the gaze direction. In a binocular device, for example, the positioning of the virtual image can be rendered non-conjugated to control the convergence and enlargement of the real image provided by the glasses optics. This binocular embodiment provides an alignment between the convergence and image magnification and better depth perception within the virtual image.

The method (method) in which adjacent retinal images generated by adjacent pixel blocks align their equal boundaries adjacent to each other can be included by zooming in the image of the AR system on the retina and separating the distance between two adjacent pixel blocks Consider and realize. By adjusting either or both of the enlargement and/or distance separation of two adjacent pixel tiles, two adjacent representative retinal images can be aligned. In addition, the pixels that cause one or more pixel tiles that overlap with an adjacent retina image or images can be removed so as to provide a boundary between two adjacent retina images.

In another embodiment, a wearer's eye moves to a location where a virtual image is generated from pixels or pixel tiles of a near-eye display. This differs in some ways from eye tracking, where the eye looks first, and then attributed the first recognition of the position of the eye to the near-eye display lighting pixels. According to the current invention, the virtual image can be moved or repositioned along the X, Y, and Z axes due to pixels or pixel tiles emitting light on the near-eye display and the eye reacting/fixing the emitting pixels or pixels instead of using eye tracking The way the AR system works. In one embodiment, the position of the virtual image when combined with the real image is achieved by locating the target position of the real image by combining information from a GPS sensor and an accelerometer that tracks head movement.

In one embodiment of the present invention, a sealed optical module(s) includes a sparsely deployed, see-through near-eye display having a transparency distance separated from a sparsely deployed microlens array by 70% or more One transparency. The sealed optical module can be bent into the shape of the base curve before the spectacle lens. Both the see-through near-eye display and the microlens array can be bent. The see-through near-eye display and the microlens array can be separated by a gap distance. The gap may be an air gap or may be filled with a material. In certain embodiments, the bending is in one direction. In certain other embodiments, the bending is in two or more directions. The pixels of the see-through near-eye display may be (by way of example only) micro LEDs (iLEDs). The size of the pixels can be 5 microns or less, preferably 2 microns or less. In certain embodiments, the pixel fill factor may be 20% or less. In certain other embodiments, the pixel fill factor may be 10% or less. The microlens fill factor of the microlens array can be 40% or less. In certain other embodiments, the microlens fill factor is 30% or less. The size of one microlens of the microlens array may be (by way of example) 400 microns to 600 microns. One or more micro LEDs can be optically aligned with one micro lens or more than one micro lens. Therefore, the plurality of micro LEDs can be optically aligned with the plurality of micro lenses. In certain embodiments, a tile of a micro LED can be optically aligned with a micro lens or a micro lens array. In certain embodiments, multiple tiles of the micro LED can provide overlapping retinal images where the overlap is 100% or less. In certain other embodiments, the size of the microlenses of the microlens array may range between 10 microns and 100 microns. In this embodiment, the diffraction caused by the microlens can be eliminated by generating a Bessel beam that travels at least a short distance without diffraction. In certain embodiments, the microlenses are aspherical. In certain embodiments, the microlenses are dichromatic. The see-through near-eye display may be an active matrix display. The see-through near-eye display can be a passive matrix display.

In an embodiment, for a pixel size of 3.5 microns, the pixel pitch may be about 5 microns. In an embodiment, for a pixel size of 1 to 2 microns, the pixel pitch may be about 3 microns. The microlens array may be a static microlens array or a dynamic microlens array. When the microlens array is dynamic, the opening and closing of the microlens array can be synchronized with the opening and closing of specific pixels or pixel tiles of the see-through near-eye display. In certain embodiments, the micro LED (iLED) is pulsed or modulated. In the aspect, the minimum modulation frequency may be 30 Hz to 60 Hz (or higher). In the aspect, the duty cycle may be 1% or higher. In certain embodiments, the duty cycle may be between 1% and 25%. In other embodiments, the duty cycle may be between 25% and 50%. In a specific embodiment, the modulation of the micro LED (iLED) can make the user's perception of the brightness of the virtual image commensurate with the user's perception of the brightness of the real world ambient light. In certain other embodiments, the modulation of the micro LED (iLED) may be such that the user's perception of the brightness of the virtual image is higher than the user's perception of the brightness of the real world ambient light. In certain embodiments, the see-through near-eye display may be monochrome. In other embodiments, the see-through near-eye display may be RGB or full color. The back side of the micro LED (iLED) furthest away from the user's eyes may be opaque or nearly opaque. This backside can be an opaque or near-opaque element of the substrate or one of the substrates attached to a micro LED (iLED). The area between micro LEDs (iLEDs) can be transparent or translucent.

In a specific embodiment of an iLED (micro LED) see-through near-eye display, the diameter of a small lens (microlens) that maintains diffraction at a low level may be about 400 to 650 microns (about 0.4 to 0.6 mm). In one aspect, in the case of a pixel size of 3.5 microns, the pixel pitch in a monochrome display may be about 5 microns. In the aspect, for a pixel size of 1 to 2 microns, the pixel pitch may be 3 microns. This means that each tile will have about 64×64 pixels or more and will be refracted through a single small lens (microlens). Given a pupil size of about 4 mm, the pupil will be partially or completely covered by about 8×8 lenslets, thus covering a field of view of about 12.5 degrees X 12.5 degrees (full macular vision). This assumption is rarely to no sparse and can be used, for example, when the substrate is transparent and the pixels are transparent. For a fill factor of approximately 2%, the number of pixels per lenslet (microlens) can be reduced from 64X64 to 9X9, or (by example) 32X32 for a fill factor of 25%. The light distribution of an iLED (micro LED) is formed as a cone, which is projected to the wearer's eyes. This can be achieved (by way of example only) by creating a recessed well in the surface of the transparent substrate and positioning the iLED (micro LED) in or within the recessed well. In other embodiments, this can be achieved by using, for example, an aperture mask surrounding an iLED (micro LED) and positioned between the iLED (micro LED) and the microlenses of the microlens array.

A specific embodiment is an AR system in which the real image is generated by the eye looking at a static position in space, and the virtual image is attributed to changing the position of the activation pixel of the see-through near-eye display while the eye remains stationary. Another embodiment is where the position of the virtual image is changed by changing the position of the different activation pixels, so that the eyes move to fix these different activation pixels (instead of using a gaze tracker to track the gaze direction), and then the virtual image is projected An AR system is changed at a position matching the gaze direction.

In yet another embodiment of an AR system, the movement of the virtual image is by changing the position of the activation pixel, so that the eye moves to be fixed to these different activation pixels (rather than generating the activation pixel relative to the position where the eye sees ) And reached. In yet another embodiment, the present invention describes an AR system in which the brightness is increased by overlapping images on the retina generated by a plurality of pixel tiles, which generate this overlap.

In an example, overlapping retinal images may have an overlap between 90% and 100% overlapping images. In other examples, overlapping retinal images have one of 100% overlap. An additional embodiment is an AR system in which a virtual image is enhanced by overlapping and dithering retinal images through pixel tiles. And in another embodiment, an AR system is taught in which virtual images are enhanced by dithering the overlapping retina images through microlenses.

In another embodiment, such as shown in FIG. 5, an array of recessed micro-conical structures is formed in the transparent substrate of the display, which is then laid out using pixels (by way of example only) iLED (micro LED). A metal coating can be applied to the sides and bottom of the micro-conical structure. By way of example only, aluminum, silver and/or tin can be used. In aspects, the coating can be optimized to have maximum reflectivity at the wavelength of light (eg, green, blue, or red) emitted by the pixel. In the aspect, the diameter of the cone may be the narrowest at the place where the pixel is deposited, which may be the deepest part of the cone (several) recessed into the cone. The diameter of the cone can be the widest on the surface of the transparent substrate. This embodiment reduces light scattering and projects light forward toward the wearer's eye.

In another embodiment, such as the embodiment shown in FIG. 9, an array of transparent pixels may be deposited on a transparent substrate. These transparent pixels may be (by way of example only) transparent iLEDs (micro LEDs). AR images can be selectively activated to provide a larger number of pixels or pixel tiles that partially or completely cover an image of a central fossa of the retina of an eye of a wearer and activate to provide partial or complete coverage of the macula and non- An image of a central fossa of a wearer's eye is enhanced by a lower number of pixels or pixel tiles.

Any one or more of the following will enhance the functionality and AR or MR experience of a person viewing through a near-eye display of a see-through transparent optical module, alone or in combination. The invention disclosed herein teaches various ways to enhance an AR or MR image. These can be (by way of example only) one or a combination of the following: 1) using a larger number of smaller pixels. Therefore, for the same level of retinal magnification, a higher resolution image can be generated; 2) aspheric microlenses are used to generate a clearer virtual image; 3) a light around a pixel block or several pixel blocks is used Aperture to reduce light scattering; 4) Use an optical aperture around a microlens to reduce light scattering; 5) Make the diameter of the microlens slightly larger than the aligned and spaced pixel tiles or microlens and one of its optical communication Pixel tiles; 6) Minimize light loss, thereby increasing the amount of light projected toward the wearer’s eyes; 7) Use multiple optical lenses that are optically aligned with the individual microlenses of the multiple microlenses of a microlens array Pixel tiles; 8) Use a curved or faceted architecture for TOM (including a see-through near-eye display and a sealed and transparent optical module with aligned and spaced microlens arrays), in various aspects, curved or small The surface architecture should (by way of example only) simulate the base curve of the spectacle lens or goggles that TOM is embedded in, attached to, or aligned at or near the front surface of the glasses. Therefore, if TOM is a 3-dimensional profile (curved or faceted) The same situation can also be applied to see-through near-eye displays and microlens arrays; 9) Dithering of pixels or pixel tiles of see-through near-eye displays; 10) Dithering of microlenses of microlens arrays; 11) Removal or Turn off specific pixel tiles or several tiles to ensure that overlapping retinal images provide an image boundary; 12) keep the magnification of the retinal image at 8 times or lower; 13) make each pixel or pixel tile concave to locate the pixel One of the surfaces of the transparent substrate is recessed into the conical structure; 14) Metalized recessed conical structure positioned within the surface of the transparent substrate; 15) An image providing a central cavity that completely or partially fills the wearer's eyes The number of active light-emitting pixels, while using a lower number of active light-emitting pixels that provide an image that completely or partially fills one of the macular areas except for the central fossa and/or 16) Use a smaller microlens, preferably having 5 to A diameter of 100 microns, and a Bessel beam that travels at least a short distance from the display completely, partially, completely, or mostly without diffraction. This Bessel beam can be switched polarized by deploying, for example, a pixel position in the display Produced by the reflector.
