Description

Near-eye display structure

The present invention relates to a near-eye display structure, in particular to a near-eye display structure that can avoid the occurrence of contrast distortion caused by overlapping of light sources.

In response to the increasing demand for real-time information in modern society, the delivery of on-demand information has received much attention. The near-eye display is portable and can update and transmit images, colors or text at any time when combined with electronic devices, so it is a good choice for portable personal information devices. Early near-eye displays were mostly for military or government purposes. Recently, some manufacturers have seen business opportunities and introduced near-eye displays to homes. In addition, entertainment-related companies are also interested in the potential of this market. For example, manufacturers of home games and games software have invested in research and development.

At present, near-eye displays (NED) include head-mounted displays (HMD), which can project images directly into the viewer’s eyes. This type of display can overcome other mobile display form factors by synthesizing a virtual large-format display surface. The limited screen size provided may be used for virtual or augmented reality applications.

The near-eye display can be further subdivided into two categories: immersive displays and see-through displays. Among them, an immersive display can be used in a virtual reality (VR) environment to use composite presentation images to completely cover the user's field of view. In augmented reality (AR) applications, see-through displays can be used, in which text, other synthetic annotations, or images can be superimposed in the field of view of the user in the physical environment. In terms of display technology, AR applications require semi-transparent displays (for example, achieved by optical or electro-optical methods), Make it possible to watch the physical world simultaneously with a near-eye display.

However, when an image is captured by the retina of the human eye, the concept of an entity 1 presenting an image 3 on the retina through a lens 2 is as shown in Figure 1. When near-eye display is required, take Google Glass as an example , Is to use the LCOS projection device to project the image on the screen 4 and then reflect to the retina of the eye to present the image 3. As shown in Figure 2, the reflected light beam will move along the optical path towards the retina, so that the image can be It is formed directly on the retina. However, this is only a single beam, and multiple beams cannot be focused on a single point. Therefore, the image is formed on the retina without focus. Therefore, Google Glass will Can cause dizziness.

In addition to the above shortcomings, the projection device has the following shortcomings if it is to be applied to near-eye and AR display:

(1) The projection angle of the projection device will limit the field of view. Generally, the maximum field of view is estimated to be less than 40 or 50°.

(2) The contrast of the projection device is strongly interfered by the background light, so when using the projection device, a darker environment or a high-brightness light source must be selected.

(3) The projection device must accurately maintain the beam path for easy display.

(4) In summary, the application of the projection device to near-eye and AR display is not convenient and not ideal.

Therefore, if the display can be used with collimation technology, it can be used as a near-eye display. In order to maintain high contrast in the output image, the area of the pixels on the display can be designed to be smaller than the area of the collimation range.

More specifically, the display can be a transparent display or a non-transparent display.

The other technical content, features and effects of the present invention will be clearly presented in the following detailed description of the preferred embodiment with reference to the drawings.

Please refer to Figures 3A to 3C, which are the display schematic diagram, the collimation implementation schematic diagram, and the imaging concept schematic diagram of the near-eye display structure of the present invention, which includes at least one display 5, which can be a self-luminous display/ A non-self-luminous display or/and a transparent display/non-transparent display, and the display 5 has a number of pixels 52 and a number of collimation regions 51 (the display 5 can be prepared through semiconductor process technology); wherein the pixel 52 is capable of emitting light source illumination to the collimation area 51, so that the incident light beam 521 that penetrates the collimation area 51 can achieve the collimation effect to form a collimated light beam 511 that is emitted outward, where the area of the pixel 52 is either The cross-sectional area of the beam 521 is smaller than the area of the collimated area 51 or the cross-sectional area of the collimated beam 511, so that the collimated beam 511 passing through two adjacent collimated areas 51 as shown in FIG. 3B The situation will not overlap and cause contrast distortion; because part of the collimated beam 511 will diverge obliquely, the larger the cross-sectional area of the incident beam 521 irradiated by the light source from the pixel 52 to the collimated area 51, the more It is easy to overlap and cause the contrast to drop. Therefore, in order to avoid unnecessary overlap and distortion of the contrast, the design makes the area of the pixel 52 or the cross-sectional area of the incident beam 521 smaller than the area of the collimation area 51 or collimation The cross-sectional area of the beam 511. In fact, therefore, the area of the pixel 52 or the cross-sectional area of the incident beam 521 will be smaller than the area of the collimated region 51 or half of the cross-sectional area of the collimated beam 511 or less ( Therefore, in addition to 1/2, it can also be 1/3, 1/4, 1/5, 1/6, 1/7, 1/8, 1/9, 1/10, 1/11..., 1/20), the effect is very obvious, However, the luminous efficiency and other factors need to be considered. Therefore, the actual area size must be corrected according to the actual situation; and the collimated display, as shown in Figure 3C, will be able to emit the light beam forward, so it will be able to reach the retina The front focus can achieve the effect of near-eye display, and combined with the above technical features, the image on the retina will be clear and not blurred, which will replace the near-eye display technology using projection devices.

Since the pixel 52 can have one or more color points, it can also be collimated for a single or multiple color points, as shown in Figures 4A to 4D, and the different situations are explained as follows;

(1) When the pixel 52 has only one color point, the color point can be respectively aligned with a single collimation area 51, so that the incident light beam 521 that the color point penetrates into the collimation area 51 can achieve the collimation effect A collimated light is formed, and the area of the color point is smaller than the cross-sectional area of the collimated light.

(2) When the pixel 52 has multiple color points, the color points of the same or different pixels can be respectively aligned with different collimation areas 51, so that each color point penetrates the incident light beam 521 of different collimation areas 51 Both can achieve the collimation effect to form collimated light, and the area of each color point is smaller than the cross-sectional area of the collimated beam.

(3) When the pixel system has multiple color points, and all the color points can be aligned with only one collimation area 51, so that a single, two or more color points penetrate the incident light beam 521 of the collimation area 51 All can achieve the collimation effect to form collimated light (which can respectively control which color point or several color points in the pixel to emit light), and the area of a single or multiple color points is smaller than the cross-sectional area of the collimated light beam.

(4) The above figures 4A to 4D show that there are one or more color points in a single pixel, and the emitted incident light beams 521 are all aligned with the same collimation area 51, but as mentioned above, although not Not shown in Figures 4A~4D, different incident beams 521 can also correspond to different collimation areas area.

The above-mentioned collimation area 51 is capable of directing light through the microlens structure or/and the optical well structure. As shown in Figure 5A, the optical well structure 53 is used for the purpose of collimation, and as shown in Figure 5B, The collimation is achieved through the microlens structure 54, or as shown in Figure 5C, the light well structure 53 is combined with the microlens structure 54 to achieve the collimation purpose. In addition, the microlens structure 54 can be guided through Angle processing to adjust the light direction after collimation; and most of the above examples are the entire area on the entire pixel, but as shown in Figure 5D, the area illuminated by the light source emitted by the pixel 52 to the collimation area 51 is Local area (rather than the entire area of the pixel 52, the light beams emitted are collimated), and the figure is implemented with the light well structure 53 and the micro lens structure 54, but it is also possible to use only the light well structure 53 for the pixel The area where the light source 52 can emit light is limited, so that the collimated beams 511 transmitted by the three pixels 52 (R, G, B) will not overlap and cause contrast distortion.

As shown in Figure 6, when the incident light beams 521, 521' emitted by the respective pixels of at least two displays 5, 5', they can be refracted at the angle of a lens 13 to overlap to form a focused scene 14 To achieve the effect of depth of field, and in order to change the depth of field, it is also possible to change the position of an image display through a software, so that the incident light beams 521, 521' emitted by the respective pixels of two or more displays 5, 5'can be in different positions Or the angle produces focus to achieve the effect of changing the depth of field.

The display 5 of the present invention can be applied to eyeglass devices. As shown in FIGS. 7A and 7B, the eyeglass device 6 includes a frame body 61 and two lens bodies connected to the frame opening 611 of the frame body 61 62. At least two displays 5 and two image capture devices 612, wherein the lens body 62 has a first surface 621 and a second surface 622, wherein the distance between the second surface 622 and the eyeball of a user is smaller than the first surface The distance between a surface 621 and the eyeball of the user, and the display 5 is bonded by bonding, plating or coating The second surface 622 of the lens body 62 (which can also be combined on the first surface 621, or both the first surface 621 and the second surface 622 have a combined display 5, which is an active light emitting display In terms of display technology, it is not an image projection technology). In addition, the lens body 62 is a flat lens or a curved lens (the curved lens is a concave lens, a convex lens, a meniscus lens, or other curved lenses).

The distance between the display 5 and the user’s eyeball is less than the photopic distance of the user’s eyeball. The photopic distance of an average person is about 20~30cm, and if the human eye is less than the photopic distance, the image cannot be focused. The distance between the display 5 and the eyeball must be designed to be less than the photopic distance, so that it can assist in imaging at a distance that cannot be focused for imaging to display near the eye.

The image capturer 612 is used to capture the image extending forward from the frame body 61, and convert the image into the external captured image information to be transmitted to the image processing module 6132, and the two image captures The fetchers 612 can be respectively arranged directly above the two eyeballs of the user, but can also be arranged around the frame opening 611 of the frame body 61.

The lens frame body 61 has a processor 613 inside. The lens frame body 61 is a hollow lens frame so that circuits and wires can be routed inside the lens frame body 61. As can be seen from Figure 8, the processor 613 is Contains a central processing module 6131, an image processing module 6132, an image output module 6133, a remote connection module 6134, a power supply module 6135, a capture angle adjustment module 6136, and an output image The adjustment module 6137, in which the central processing module 6131 is used to control the overall processor operation, and the externally captured image information captured by the image extractor 612 can be processed by the image processing module 6132 The image is cleared to improve its resolution; the remote connection module 6134 is used for remote connection by wireless connection technology, and the power supply module 6135 is used for connection with an external device, To store and provide the power required for the operation of the processor, a power supply socket electrically connected to the power supply module 6135 can be added to the lens frame body 61 (Not shown in the figure), so that it can be charged with an external wire or USB transmission line; in addition, the power supply module 6135 (battery) can be designed as a detachable component on the frame body 61, so that the After the detachable component is removed, the power supply module 6135 (battery) can be replaced.

The image output module 6133 can output the externally captured image information after the image has been clarified as a synchronized clarified image to the display 5, and the user wearing the glasses device 6 can display it on the display 5. After seeing the synchronized clear image, you can connect to a cloud platform 12 through the APP platform of a handheld device 11 as shown in Figure 9 (but you can also directly connect the APP platform of the handheld device 11 and the glasses device 6 The remote connection module 6134 connects directly), and the cloud platform 12 connects with the remote connection module 6134 of the glasses device 6, and the user can operate the APP platform to input and control output The image adjustment command, when one side is adjusted, the adjustment command will be sent to the output image adjustment module 6137 through the cloud platform 12, remote connection module 6134 and central processing module 6131 to proceed according to the adjustment control command Adjust the display status displayed in the synchronized clear image, so the user can continue to control the APP platform to make fine adjustments while watching the adjusted status, so that the user can adjust to the display status mentioned here. It can adjust multiple display angles (in addition to the direct view of the eyeball, it also provides images of multiple views around the direct view of the eyeball, and allows the user to use his or her eyeball up, down, left, upper left, lower left, Right, upper right, lower right, etc., to fine-tune the accuracy of the image alignment seen by different eye angles), adjust the display position (up, down, left, top left, bottom left, right, top right, bottom right) Wait for at least eight directions to fine-tune), adjust the display size (zoom in or out), adjust the display contrast, adjust the display brightness (brighter or darker), or adjust the wide angle. In addition, if there is any need to synchronize the clear image A font, the adjustment control command can also input commands such as font replacement, so that the output image adjustment module 6137 will display the characters on the display 5 in a synchronized clear image The body is replaced with clear fonts; in addition, when the scene seen is day or night with insufficient light, the synchronized clear image will display a darker image, so users can also use the APP platform to input light Compensation and other commands, so that the output image adjustment module 6137 can perform light compensation for the synchronized clear image displayed on the transparent display, so that night vision can also be achieved.

In addition to replacing fonts, if there are any replaceable objects on the synchronized clear image, it can be replaced by the built-in objects of the processor 613, and the built-in objects such as pictures, images, people Face images, text, buildings, biological features, etc.

The aforementioned image processing module 6132 and the output image adjustment module 6137 are built in the frame body 61, but the remote connection module 6134 can also directly upload the captured images to the cloud platform 12 Since the cloud platform 12 can achieve the functions of the image processing module 6132 and the output image adjustment module 6137, it can replace the image processing module 6132, the capture angle adjustment module 6136, and the output image adjustment module 6137 After the image is processed and sent back to the remote connection module 6134 of the lens frame body 61, the processed image is directly output to the display 5.

In addition, the output image adjustment module 6137 can also process images in an array and/or matrix (matrix) manner, so that the image output to the display 5 will have image focus when viewed by the user’s eyeballs. Effect. And when the multi-layer display 5 is attached to the lens body 62, since the images output to one of the displays or any two or more of the displays 5 are processed in an array or matrix manner, the effect of multiple image focusing can be achieved.

In addition, various collimation technologies (such as microlens array or light well technology) are used on the lens body 62 or the display 5 to guide the light. The microlens technology changes the light through at least one lens. The light well technology transmits through a light well so that the light passing through the light well can go straight forward; The microlens can be processed with a lead angle to adjust the direction of the collimated light. In addition, the display 5 can also be processed by collimation technology or microlens technology during the manufacturing process. So that the display 5 itself has a structure similar to a microlens or light well after leaving the factory, so that the display 5 has the effect of guiding light.

In addition, the lens body 62 or the display 5 itself can undergo chamfering, and the lens body 62 or the guide angle of the display 5 can adjust the collimated light direction, so that more than two images can be overlapping.

In addition, when the images displayed on the two different left and right displays 5 are at different angles, when the user sees the two different left and right displays 5 with the left and right eyes, the user can feel the depth of field or Three-dimensional image effects, and images of different angles can be captured by two or more image capture devices 612 (and the image capture device 612 can also set the angle to capture images); , It is possible to use two or more image capture devices 612 to capture images of different angles, and then use the processor 613 to merge the captured images from different angles to obtain a depth-of-field or three-dimensional effect Image information (combined into one image with more than two different angles), and output to the display 5 (images with more than two different angles can be displayed on different displays 5), and the above-mentioned merging process is also It can be calculated on the cloud platform 12 and then sent to the glasses device 6.

In addition, the 2D image (digital display data) stored in the cloud platform 12 can be captured or downloaded on the cloud platform 12 through the remote connection module 6134 of the frame body 61, and then output The image adjustment module 6137 processes 2D images into images of different angles, so that different displays 5 can display images of different angles (digital display data) to present a sense of depth or three-dimensionality In addition, the cloud platform 12 can also store processed digital display data from different angles or directly upload the 2D images captured by the image capture device 612 to the cloud platform 12, so that the cloud platform 12 12 After processing the 2D images into images of different angles, and then return them to the remote connection module 6134 of the frame body 61, the images of different angles are directly output to different displays 5.

In addition, since the quality of the image capture device 612 will affect the resolution of the captured image, and the quality of the display 5 will also affect the resolution of the synchronized clear image broadcast, if you want to improve the resolution of the image, you can also Improve the quality of the image capturer 612 and the display 5, and use hardware to improve the resolution of the output image.

In addition, since the angle captured by the image capture device 612 may not be exactly the same as the viewing angle seen by the user's eyeballs, if the angle captured by the image capturer 612 can be seen by the user's eyeballs The viewing angles are exactly the same. The image actually seen by the user’s eyeball through the lens body 62 will overlap with the synchronized clear image displayed on the two displays 5. Therefore, generally the capture angle adjustment module 6136 will default to one Fix the angle of the eyeball perspective (for example, the direct viewing angle), and adjust the angle of the image captured by the image capture device 612 according to the fixed eyeball perspective angle, so that the image seen by the eyeball perspective can be the same as the image captured by the image capture device. The image extending forward of the frame body 61 is taken as the same angle of view; but the above situation is the factory default when the product is shipped, so when the user actually uses the glasses device 6, if the image displayed on the display 5 is not When it cannot overlap with the actual scene seen by the eyeball, it means that the angle of the image captured by the image capture device 612 is wrong. Therefore, the user can also connect to a cloud platform 12 through the APP platform of the handheld device 11 (but It can also directly connect with the remote connection module 6134 of the glasses device 6 through the APP platform of the handheld device 11), and the cloud platform 12 will connect with the remote connection module 6134 of the glasses device 6 After connection, the user can operate the APP platform to input control commands to the capture angle adjustment module 6136 to indirectly adjust the image capture The angle at which the image capture device 612 needs to capture the image, so when the APP platform adjusts, the image capture device 612 will also rotate the lens, and the image displayed on the display 5 will also move until the user feels the eyeball passes through the The image actually seen by the lens body overlaps with the synchronized clear image displayed on the two transparent displays, and then this adjustment is completed (in this state, it means that the image viewed by the eyeball can be captured with the image The image that the lens frame body extends forward captured by the extractor 612 has the same angle of view).

In addition, the image capture device 612 can set the function of wavelengths other than visible light, so that the image capture device 612 can capture images of wavelengths other than visible light, so that it can capture clear images clearly at night (night Depending on the function) or capturing ultraviolet rays, etc., and the present invention is capable of capturing ultraviolet rays, so it can further design ultraviolet warning software to cooperate with the captured images.

In addition, the image capture device 612 has the functions of zooming in and out. Like a camera, it can zoom in and zoom in the image to be captured in the distance (similar to a telescope) or directly zoom in the image (similar to In the magnifying glass), so no matter it is farther or closer, you can capture clear images.

However, the output image adjustment module 6137 can also add an eye tracking function to track the angle of the eyeball at any time, and adjust the angle of the image captured by the image capture device 612 according to the angle of the eyeball, so that the user does not need to use The remote is manually adjusted through the APP platform, but it can be adjusted automatically.

The first embodiment of the present invention is shown in Figs. 10A to 10B. Fig. 10A is a general near-sighted view of the eyeball. The eyeball 7 is too long (that is, the distance between the lens and the omentum is too long), or because the lens is facing a distant object. The zooming ability declines, so that the far point is very close, beyond the far point of the scene 8, the blurred scene 72 generated by the cornea 71 will fall in front of the retina, and a blurred image on the retina, so look It is not clear, but it can be seen from Figure 10B that if the eyeglass device 6 is worn, the display 5 is provided in front of the eyeball 7, although the eyeball 7 sees through the lens body 62 (flat lens). The object 8 is also a blurred image on the retina, but since the image capture device 612 directly captures the image of the scene 8 and then undergoes image sharpening processing to improve its resolution, it can be displayed on the display 5 The upper display shows a synchronized clear image 81; since the synchronized clear image 81 is displayed very close to the eyeball 7, the synchronized clear image 81 will present a clear scene 73 on the retina of the eyeball 7, so that after processing The image of is able to overlap on the retina. Although the clear image 73 has a blurred image 72 in front of it, the mechanism of the eyeball 7 is to capture the clear image, so the eyeball 7 will focus on the clear image 73 and ignore the blur The scene 72, so the final image seen is the clear scene 73 (the blurred scene 72 can be regarded as being replaced by overlapping), so the present invention will enable the myopia to achieve correction even without wearing myopia glasses. Effect (similar to myopic people, although they look far away is very blurry, but they look close will be very clear. Therefore, after the image capture device 612 captures a very far view, the display 5 plays it on the user's eyeball 7The front will make the distant view very clear).

The second embodiment of the present invention is shown in Figs. 11A~11B. Fig. 11A is a schematic diagram of general hyperopia. The eyeball 9 is too short, or the lens’s ability to zoom near objects is degraded. The distance is very long, so when the scene 8 comes in by the cornea 91, the blurred scene 92 generated by the cornea 91 will fall behind the retina, which will cause the situation to be unclear. However, it can be seen from Figure 11B that if it is worn In the glasses device 6, there is the display 5 in front of the eyeball 7, although the scene 8 seen by the eyeball 9 through the lens body 62 (planar lens) is also a blurred image on the retina, but due to the image capture The device 612 directly captures the image of the scene 8 and then undergoes image sharpening processing to improve its resolution, and then the synchronized sharpened image 81 can be displayed on the display 5; because hyperopia is prone to unclear vision, Therefore, people who cause hyperopia will also be used to seeing things more clearly than ordinary people. Therefore, when the front of the eyeball 9 is displayed, the display is very clear. At the time of the image, the synchronized clear image 81 will display a clear scene 93 on the retina of the eyeball 9, so that the processed image can be superimposed on the retina, although there is a blurred scene 92 behind the clear scene 93 However, the mechanism of the eyeball 9 is to capture a clear image, so it ignores the blurred scene 92 and focuses on the clear scene 93. This will enable the hyperopic person to achieve the corrective effect even without wearing hyperopic glasses.

The third embodiment of the present invention is shown in Figures 12A to 12B. Figure 12A is a schematic diagram of general myopia correction with a concave lens 10. It can be seen from the figure that when the user wears the lens of the concave lens 10, it can Make the eyeball 7 see a clearer scene 74 as much as possible, but the human eyeball has a limit after all. If it is too far away, the scene you see will become blurred with the distance, but it can be seen from Figure 12B If the glasses device 6 is worn, there is the display 5 in front of the eyeball 7, even if the scene 8 is very far away, but if the image capture device 612 can capture the distant image, and the image is clear After processing to improve its resolution, the display 5 displays the synchronized clear image 81, which is equivalent to capturing the distant image directly in front of the eyeball 7 for display, so that the processed image can be overlapped on the retina. In this way, even a scene beyond the visible range of the eyeball can clearly present a clear scene 75 on the retina of the eyeball 7.

In addition to the correction with concave lenses, even other eye problems, regardless of whether you wear curved lenses for correction, can be combined with curved lenses to achieve the same effect.

而透過上述公式，當明視距離為25cm時、f算出來約1.59，但以年輕人的眼睛來看，其眼睛可看清楚的最近距離約6.5公分，依此，人眼球焦距可調整的範圍不超過20%，所以水晶體的焦距極限不會低於1.32公分，所以進一步換算出極限的成像距離(p)(1/p+1/1.7=1/1.32)約為6公分。 Since this case is used for near-eye display, the photopic distance of a normal person is about 25 cm, and the distance (q) between the lens and the retina is about 1.7 cm. The focal length f of the lens can be calculated by the following formula, which is as follows:

According to the above formula, when the photopic distance is 25cm, f is calculated to be about 1.59, but from the eyes of young people, the shortest distance that their eyes can see clearly is about 6.5 cm. According to this, the range of human eyeball focal length can be adjusted No more than 20%, so the focal length limit of the lens will not be less than 1.32 cm, so the imaging distance (p) (1/p+1/1.7=1/1.32) of the limit is about 6 cm.

It can be seen from the above that when the focal length of the lens is less than 1.32 cm, it means that the eye has a certain problem and cannot see clearly at a normal distance. Therefore, when the display of the present invention is placed within this range, it can assist the eye You can see clearly through the display, and the distance from the object to the lens (object distance) calculated by the focal length of the lens is as follows: (1) When the focal length of the lens is 1.31 cm, through the calculation of formula (1) (1/p+1/1.7= 1/1.31), it can be calculated that the object distance (p) is about 5.88cm; (2) When the focal length of the lens is 1.19 cm, through the calculation of formula (1) (1/p+1/1.7=1/1.19), the object distance (p) can be calculated to be about 4cm; (3) When the focal length of the lens Is 0.8 cm. Through the calculation of formula (1) (1/p+1/1.7=1/0.8), the object distance (p) can be calculated to be about 1.5 cm; (4) When the focal length of the lens is 0.39 cm, through the formula The calculation of (1) (1/p+1/1.7=1/0.39) can calculate that the object distance (p) is about 0.5cm; because the display is set too far or too close, it will cause inconvenience to the user Therefore, the present invention designs that the distance between the display and the eyeball is 0.5~4 cm, which is the best distance, and it is also the most suitable wearing distance for users with eye diseases.
