FIELD OF THE INVENTION

The present invention pertains to an augmented reality (AR) system that projects information over the real world object. The same system can be used as a virtual reality (VR) system as well where all the images shown and visible to viewers are generated by the display. A system that can be used for both applications is sometimes called mixed reality (MR) system.

SUMMARY

DETAILED DESCRIPTION OF THE INVENTION

An augmented reality (AR) system projects information over the real world object. The same system can be used as a virtual reality (VR) system as well where all the images shown and visible to viewers are generated by the display. A system that can be used for both applications AR and VR)is sometimes called mixed reality (MR).

The main parts of AR, VR, or MR systems are displays, optics, interfaces, and computing systems. The interface is used to interact with the user and also with the information sources. The display creates the images, and the optical system enables the image to be presented as augmented or virtual reality for the user. While interfaces and computing systems can be hidden away from the face, the optical system and displays are mainly on the face of the viewers. Therefore, having a compact structure for the optical system and displays is essential for ease of use.

In one embodiment, a display is shaped as one of the optical components. Here, the display can be flexible and molded into the optical structure shape.

FIG. 1 shows one related embodiment of using display as an optical component. Here, an MR system 100 has a convex curved display 102 and a concave or linear mirror 104 projecting the light from the display 102 into a viewer's eye 106. The mirror 104 can be a flat with pinhole optics. The mirror 104 can be semi-reflective or holographic. The display 102 can have micro-lenses for confining the light.

The radius of the curved display 102 and the concave mirror 104 are designed to provide the magnification, and focal distance. The display 104 can be curved in all directions or only curved in one direction. This direction can be in perpendicular with the mirror edge that the curved display 102 is close to. As a result, the image will be magnified in one direction only.

In one embodiment, the magnification by optics and display curvature is done in one direction. As a result, the display is elongated/stretched in a direction that is close to the edge of the mirror to increase the use of the field of view.

FIG. 2 (2A and 2B) shows the curved display pixels 210 that can be stretched in one direction for example in the direction parallel to the edge of the mirror close to the display 102. FIG. 2A shows a stretched display 202 in one direction and one pixel 210 consists of multiple sub-pixels 212, 214 and 216. The pixel 210 is stretched in the same direction as the display 102. Also, the sub-pixels can be stretched or spaced sparsely to compensate for the extra space created by the stretched structure.

As shown in FIG. 2B, to increase the effective resolution, the sub-pixels can be arranged so that there is no similar sub-pixel adjacent vertically and horizontally. Stretching can be done as part of the fabrication and design. Here, the display is designed with longer pixels in one direction. In another case, the display is stretched after fabrication.

In another related case demonstrated in FIG. 3, more than one display 102r, 102g, and 102b, can be used to create the image on the optical component 104. The displays 102r, 102g, and 102b can be arranged as part of the optical structure. In one related case, the displays can be linear arrangements. In another case, the displays are formed either as concave, convex or combination of both. Here the displays 102r 102g 102b can be different colors and so the combination of the displays and projection from the mirror 104 shows the full color. Here, to align the pixels from each display with each other, a test image is shown by each display and reflected on the mirror. The position of each pixel in the display is calculated in the mirror 104. The pixels in the displays that have close proximity in the mirror are grouped as one combined pixel. The image is remapped to each display based on the new grouping.

While the present disclosure is susceptible to various modifications and alternative forms, specific embodiments or implementations have been shown by way of example in the drawings and are described in detail herein. It should be understood, however, that the disclosure is not intended to be limited to the particular forms disclosed. Rather, the disclosure is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of an invention as defined by the appended claims.
