Description

Near-eye display method with focusing effect

The present invention relates to a near-eye display method with a focusing effect, in particular to a method in which a beam emitted by any pixel on one or two display modules is overlapped to generate focus so that the output image can be clearly displayed. The near-eye display method.

In response to the increasing demand for instant information in modern society, the delivery of on-demand information has received much attention. The near-eye display is a good choice for portable personal information devices because of its portability and the ability to update and deliver images, colors or text at any time in conjunction with electronic devices. Early near-eye displays were mostly military or government use. Recently, some manufacturers have seen business opportunities and introduced near-eye displays to homes. In addition, entertainment-related industry also sees the potential of this market, such as home game instruments and game software related manufacturers have invested in research and development.

Currently, the near-eye display (NED) includes a head-mounted display (HMD) that projects images directly into the viewer's eyes. This type of display can overcome other action display form factors by synthesizing a virtual large-format display surface. Available in a limited screen size, or for virtual or augmented reality applications.

The near-eye display can be subdivided into two major categories: immersive displays and see-through displays. An immersive display can be employed in a virtual reality (VR) environment to fully encompass the user's field of view using a composite rendered image. In augmented reality (AR) applications, a see-through display can be used in which text, other synthetic annotations, or images can be overlaid in the field of view of the user in a physical environment. In terms of display technology, AR applications require a translucent display (eg, by optical or electro-optic methods) such that a near-eye display can be used to simultaneously view the physical world.

However, since the human eye cannot focus (focus) on the fact that the object is placed at a close distance (for example, when the user is wearing glasses, reading the distance between the lens of the magnifying glass and the user's eyes). Difficult to construct. Therefore, the near-eye display must be adjusted to make the viewer comfortable to use, otherwise it will cause the occurrence of defocusing and other effects, but the traditional use of complex and cumbersome optical components to adjust, but because of the near-eye display Most of them must be worn directly on the viewer's head, so the near-cuddly near-eye display is often not acceptable to consumers.

Therefore, in order to overcome the above problem, if the beams emitted by any of the pixels on one or two display modules can be overlapped to produce focus, so that the output image can be clearly displayed, thus eliminating the need for bulky optics. Components, and can also save the extra cost of using bulky optical components, this should be an optimal solution.

The near-eye display method with the above-mentioned focusing effect can be achieved by: (1) being capable of providing at least one or at least two display modules and at least one image output module disposed on the near-eye display. And outputting at least one image to the display module through the image output module; and (2) a beam system emitted by any one of the pixels of the one or at least two collimated display modules The images can be overlapped so that the image output by the image output module can be focused by overlapping the beams emitted by the at least two pixels.

More specifically, the lead angle technique is to perform a cornering process for each pixel or a cornering process for each image so that the angle of each image output to the display module is different.

More specifically, the range of light beams emitted by any of the pixels on the display module is expanded to allow portions of the light beams emitted by any of the two display modules to overlap naturally. The image output by the image output module can be focused by overlapping the beams emitted by at least two or more pixels.

More specifically, any of the pixels on the display module can emit an angle range of 0 to 40 degrees.

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

More specifically, the display module that uses only one collimation technique can perform time-difference interactive imaging so that the beams emitted by any of the pixels can overlap at least twice in a short time to generate focus.

More specifically, the display module can be a flat single layer display, a flat multi-layer display, a curved single layer display, a curved multi-layer display, or a flat/curved multi-layer display.

More specifically, when the display module is a curved multi-layer display or a planar multi-layer display, beams emitted by any of the pixels on different layers overlap to produce a focused image, which may result in different focusing distances due to multiple layers. To be able to change the depth of field.

More specifically, the near-eye display further includes a light field capturing module, wherein the light field capturing module is capable of capturing and capturing a multi-point light field signal of the image in front of the display module, and inputting the In the display module, the multi-point light field signal is transmitted by the display module through a plurality of pixels to emit a light beam, and the light beams emitted by the plurality of pixels overlap to generate an image in which the multi-point light field is represented by focusing.

More specifically, the multi-point light field signal captured by an external device can be captured by the display device, and the captured multi-point light field signal is transmitted through a plurality of pixels to emit a light beam. The beams emitted by the plurality of pixels overlap to produce an image in which the focus represents a multi-point light spot.

More specifically, the near-eye display further includes an image adjustment module, wherein the image adjustment module is coupled to the image output module for enabling the image output by the image output module to pass through The beams emitted by the at least two pixels overlap to produce a focused image for comparison and adjust the overlapped angle so that the focused image can be identical to the image output by the image output module.

Other details, features, and advantages of the present invention will be apparent from the following description of the preferred embodiments.

Please refer to FIG. 1 , which is a schematic flow chart of a near-eye display method with a focusing effect according to the present invention. The steps are as follows: (1) capable of setting at least one or at least two collimated on a near-eye display. a technically processed display module and at least one image output module, wherein at least one image can be output to the display module 101 through the image output module; and (2) and one or at least two are processed by collimation technology The beams emitted by any of the pixels on the display module can be overlapped such that the image output by the image output module can be focused by the beams emitted by the at least two pixels to produce the focus 102.

As shown in FIG. 2, the near-eye display 2 has at least one display module 1, an image output module 2, an image adjustment module 3, and a light field capture module 4, wherein the display module 1 The collimation technique is used to guide the direction of the light beam emitted by any of the pixels on the display module, and the collimation technique is as follows: (1) In the display mode Group 1 uses a microlens technology to direct light through at least one microlens; (2) directing light through a light well technique on the display module, wherein the light well technique Through a light well, the light passing through the light well can be straight forwarded (3) the light beam technology is combined with the light well technology to guide the light on the display module; (4) in the manufacturing process of the display module 1 The use of collimation technology or microlens technology for processing, so that the display module has the effect of guiding the light to achieve the purpose of image focusing.

Further, it can be seen from FIG. 10A that when the light source 11 passes through the light well 112 formed by the above-mentioned optical well technology, the light 110 will advance straight, but because the light has the characteristics of scattering, part of the light 110 will still diverge, so As shown in Fig. 10B, if a microlens 113 is added to the optical well 112, the divergent light will be directed to allow the light 110 to go straight out.

However, in order to allow the beam lines emitted by any two pixels to overlap and produce focus, the present invention must be processed by a lead angle technique to adjust the image display angle of the beam emitted by any pixel, wherein the lead angle technique The processing is to perform a cornering process for each pixel or a cornering process for each image, so that the angle of each image outputted to the display module is different.

The lead angle technique mentioned in the present invention is to perform a cornering process for each pixel or a cornering process for each image, so that the angle of each image outputted to the display module 1 is different, so that two More than one image can be overlapped and merged. The above-mentioned lead angle technique is described as follows: (1) The lead angle processing can be performed on the display module 1 itself so that the lead angle of the display module 1 can be adjusted. In the direction, two or more images can be overlapped and merged; (2) the image display angles outputted by the image output module 1 can be different, so that two or more images can be overlapped and merged. In this state, the image must be adjusted. The image output module 2 itself outputs the angle of the image.

When the near-eye display uses two display modules 1, since both display modules 1 are processed by the collimation technique, each pixel can directly emit a light beam, and then adjust the pixel by the lead-angle technique. The image display angle of the emitted light beam is as shown in FIG. 3A. The display module 1 has a plurality of light sources 11 (Lens), and the light source 11 has a plurality of pixels 111 (pixel). The pixel 111 can be adjusted for three values of RGB, for example, the pixel 111 can be adjusted to be an R value, a G value, or a B value);

Further, as shown in FIG. 3B, the illumination source 11 on the front surface of the display module 1 can have a plurality of different/identical RGB pixels 111 (for example, the inside of the illumination source 11 can be more than one different/same RGB pixels 111). Or, it is possible to have only one pixel 111 inside the light source 11 (the pixel 111 can be an R value, a G value, or a B value).

The display module 1 can be a transparent display or a non-transparent display, and the display module 1 can also be a flat single layer display, a flat multi-layer display, a curved single layer display, a curved multi-layer display or a flat/surface Multi-layer display, and for multi-layer display is as follows: (1) When the display module 1 is a curved multi-layer display, the beams emitted by any of the pixels on different layers overlap to produce a focused image, which may result from multiple layers. Different focusing distances to change the depth of field; (2) When the display module 1 is a flat multi-layer display, time-interval interactive imaging is required to enable the beam emitted by any pixel on different layers to be delivered. Stacking produces a focused image, while a flat-panel multi-layer display produces different focus distances due to the multi-layer structure to change the depth of field.

As shown in FIG. 4, when the display module 1 is a planar multi-layer display, the beams emitted by the pixels aligned by the first layer plane 12 and the second layer plane 13 can overlap to form a human eye 5 to be seen. Focus image 61 to.

As shown in FIG. 5, when the display module 1 is a curved multi-layer display, the beams emitted by the pixels aligned by the first layer curved surface 14 and the second layer curved surface 15 can overlap to form a human eye 5 to be seen. The focused image 62 is obtained, but due to the characteristics of the curved surface, it is possible to adjust the image size of two or more curved surfaces or adjust the curvature of the curved surface to make the beam emitted by the collimated pixel more accurate. overlap.

As shown in FIG. 6, when the display module 1 is a curved/planar hybrid multi-layer display, the beams emitted by the pixels aligned by the first layer plane 16 and the second layer curved surface 17 can overlap to form the human eye. 5 can see the focused image 63, but due to the characteristics of the curved surface, it is necessary to adjust the image size of two or more curved surfaces or adjust the curvature of the curved surface, so that the beam emitted by the collimated pixel can More accurate overlap.

As shown in FIG. 7 , when the display module 1 is two planar single-layer displays, the beams emitted by the pixels of the two different display modules 1 can be overlapped to form a focused image that can be seen by the human eye 5 . 64.

In addition, when the display module 1 is a two-plane single-layer display, the range of light beams emitted by any of the pixels on the two display modules 1 can be expanded, as shown in FIG. The light beams emitted by any of the pixels on the display module 1 can partially overlap, so that the image output by the image output module 2 can be overlapped by the beams emitted by the at least two pixels to generate a focused image. 65, wherein any of the pixels on the display module 1 emits a range of light beams ranging from 0 to 40 degrees.

When the display module 1 is a single flat/curved single-layer display, since it is not possible to use two display modules 1, it is necessary to perform time-difference interactive imaging to make a light beam emitted by any pixel in a short time. The focus can be overlapped at least twice, as shown in FIG. 9A, one of the pixels on the display module 1 will first emit the first beam image 66, and then, as shown in FIG. 5B, the display The other pixel on the module 1 will first emit a second beam image to overlap the first beam image 13 to form a focused image 67 that can be seen by the human eye 5.

In addition, the light field capturing module 4 can capture and capture the multi-point light field signal of the image in front of the display module 1 and input it into the display module 1 to be multi-pointed by the display module 1 The light field signal emits a light beam through a plurality of pixels, and the light beams emitted by the plurality of pixels overlap to generate an image that is focused to represent a multi-point light field;

To further explain the light field technology, the so-called light field refers to the collection of light in any direction from any point in space. In the case of a light field camera, it is a lens (Main Lens) and image of a general camera. In the middle of the sensor (Photosensor), insert a microlens array (Microlens Array) consisting of neatly arranged miniature lenses, one for each pixel;

Therefore, the light field camera (light field capturing module 4) can completely record the information of most of the light transmitted through the lens, such as the intensity of the light, the trajectory of the light, the direction of the light, etc., and the present invention further develops the information of the light. a beam of light emitted by a pixel and generated by at least two overlappings to present a focused image represented by a multi-point light spot;

However, the present application can also transmit the multi-point light field signal captured by an external device to the near-eye display 2 without using the light field capturing module 4 (instead of transmitting the optical field through the optical field). The group 4 captures the multi-point light field signal), and then the display module 1 transmits the captured multi-point light field signal through a plurality of pixels to emit a light beam, and the light beams emitted by the plurality of pixels overlap. Producing an image showing the focus of the multi-point light scene.

In addition, since the image displayed by the conventional light field camera is a 2-dimensional plane image, after the technique of the present application, the display module 1 transmits the multi-point light field signal captured by the plurality of pixels to emit a light beam. And generating a focused image representing a multi-point light field by overlapping the beams emitted by the plurality of pixels, and generating a focused image due to the overlapping of the beams emitted by any of the pixels on the different layers, because Multiple layers and different focusing distances can be used to change the depth of field. Therefore, the present application can recover the multi-spot light field signal through the multi-layer structure to restore the image with depth of field (the processing output of the general light field signal can only present a plane, and Can't achieve the effect of depth of field).

In addition, since the focused image and the actual image may have some errors, the image output module 2 connected to the image output module 2 must pass through at least two of the images output by the image output module 2. The beams emitted by the pixels overlap to produce a focused image for comparison and adjust the overlapped angle to adjust the focused image to be as close as possible or identical to the image output by the image output module.

The near-eye display method with focusing effect provided by the present invention has the following advantages when compared with other conventional techniques: 1. The present invention enables the beam emitted by any pixel on one or two display modules to be delivered. The overlay creates focus so that the output image can be clearly rendered, which eliminates the need for bulky optical components and also saves the extra cost of using bulky optical components.

The present invention has been disclosed above by the above-described embodiments, and is not intended to limit the present invention. Any of those skilled in the art can understand the foregoing technical features and embodiments of the present invention without departing from the present invention. In the spirit and scope of the invention, the scope of the invention is to be determined by the scope of the appended claims.
