Description

Reflective display

The present invention relates to a reflective display, and more particularly to a reflective display that can be worn on a user's head.

With the development of display devices, the size and weight of display devices have progressed toward miniaturization. In recent years, head-mounted displays have been developed as an image display for virtual reality (VR) systems to be worn on the user's head, and the field of application is becoming more widespread. However, the conventional head-mounted display is because the horizontal and vertical curvature of the mirror must be changed according to the user's angle of view in order to make the image appear in front of the user at a close distance. If the curvature of the mirror is fixed, the seriousness will occur. The image is distorted, which greatly increases the difficulty and cost of mirror fabrication.

Therefore, how to easily create a mirror that allows an image to be presented at a close distance in front of the user without distortion is still to be solved.

The advantages and features of the present invention, as well as the technical methods of the present invention, are described in more detail with reference to the exemplary embodiments and the accompanying drawings. The embodiments of the present invention are to be construed as being limited by the scope of the present invention, and the invention The scope of the patent application is defined.

One or more embodiments of the present invention disclose a reflective display. The reflective display disclosed in the following embodiments can effectively reduce the manufacturing cost and distortion of the mirror, and the effect of generating multiple viewing angles.

Fig. 1 is a schematic view showing a reflective display according to a first embodiment of the present invention. Referring to FIG. 1 , a reflective display includes a headset 11 , a mask 20 , a mirror 22 , and an image display module 30 . The mask 20 can be disposed on the headgear 11 (for example, pivoted by the pivoting portion 21), and corresponding to the front of the user 40, the mask 20 can be a transparent or partially penetrating windshield. In other words, the mirror 22 can be disposed on the mask 20, for example, by magnetic attraction, pasting, clamping, snapping, locking, or integral molding, and corresponds to the position of the eye 41 of the user 40, wherein the reflection The mirror 22 can be, for example, a concave mirror and can be, for example, a mirror 22 having partial and partial transmission characteristics. In addition, the image display module 30 can be disposed on the headgear 11 by magnetic attraction, pasting, clamping, snapping or locking, and the image display module 30 and the mirror 22 are oppositely disposed, and the image can be projected. Light ray 34 to mirror 22 is reflected by mirror 22 to eyeball 41 of user 40 to form a virtual image as seen by user 40. The horizontal axis curvature and the vertical axis curvature of the mirror 22 are suitable for reflecting the light 34 of the image to the eye 41 of the user 40. For example, the mirror 22 is snapped to a position of the mask 20, and is adapted to reflect the light 34 of the image to the eyeball 41 of the user 40. The curvature of the horizontal axis is 100 mm in diameter and the curvature of the vertical axis is 80 mm in diameter. The mirror 22 reduces the difficulty of creating different curvatures of the mirror 22 at different locations.

In the above, by placing the mirror on the mask by magnetic attraction, sticking, clamping, snapping or locking, the user can select whether or not to use the mirror, thereby increasing the convenience of use. The mirror is made by reflecting the horizontal axis curvature and the vertical axis curvature of the eyeball of the user's eyeball, thereby reducing the manufacturing cost of the mirror and avoiding image distortion.

2 is a schematic view of a reflective display according to another embodiment of the present invention. Referring to FIG. 2, the reflective display can further provide a plurality of mirrors 22a, 22b, 22c at different positions on the mask 20, for example, by magnetic attraction, pasting, clamping, snapping, locking or integral molding. 22d, and corresponding to the position of the eyeball 41 of the user 40, and the plurality of image display modules 30a, 30b, 30c, 30d, respectively, can be respectively set by magnetic attraction, pasting, clamping, snapping or locking. The headgear 11 and the plurality of image display modules 30a, 30b, 30c, and 30d are disposed opposite to the plurality of mirrors 22a, 22b, 22c, and 22d. For example, the image display module 30a is a light ray 34a that can project an image. To the mirror 22a and the image display module 30b, the light 34b of the image can be projected to the mirror 22b, and so on. The plurality of image display modules 30a, 30b, 30c, and 30d respectively project a vehicle state information image, a navigation information image, a road image, or a dead angle image to a plurality of mirrors 22a, 22b, 22c, 22d, such as images. The display module 30a can project the dead angle image to the mirror 22a and the image display module 30b, and can project the vehicle state information image to the mirror 22b and the image display module 30c, and can project the navigation information image to the mirror 22c.

In addition, the horizontal axis curvature and the vertical axis curvature of the plurality of mirrors 22a, 22b, 22c, and 22d are mirrors formed by the horizontal axis curvature and the vertical axis curvature suitable for reflecting the light of the image to the eyeball of the user. For example, the mirror 22a is adapted to reflect the light ray 34a of the image to the eyeball 41 of the user 40 having a horizontal axis curvature of 100 mm in diameter and a vertical axis curvature of 80 mm in diameter, and the mirror 22b is adapted to reflect the light ray 34b of the image to use. The horizontal axis curvature of the eye 41 of the person 40 is 90 mm in diameter and the curvature of the vertical axis is 90 mm in diameter.

In the above, by providing the mirrors at different positions of the mask, the user can provide more driving information, and the mirror can be made by reflecting the horizontal axis curvature and the vertical axis curvature of the eyeball of the user's eyeball. Mirror manufacturing costs and avoid image distortion.

Please refer to FIG. 1 to further describe the structure of the image display module 30. The image display module 30 can include a screen 31 and a micro projector 32. Taking a transmissive screen as an example, the micro projector 32 is used to project an image onto the screen 31 so that the image is presented on the screen 31. At this time, the light 34 of the image penetrates the screen 32, and then the light 34 of the image is projected onto the mirror 22 to be reflected by the mirror 22 to the eye 41 of the user 40 to form a virtual image seen by the user 40. However, the present invention is not limited thereto, and the image module 30 may be only a liquid crystal display device for providing images and projecting to the mirror 22.

In summary, by placing the mirror on the mask by magnetic attraction, pasting, clamping, snapping or locking, the user can select whether or not to use the mirror, thereby increasing the convenience of use, and It is suitable for reflecting the horizontal axis curvature and the vertical axis curvature of the image of the user's eyeball to make the mirror, which can reduce the manufacturing cost of the mirror and avoid image distortion. In addition, the mirror can be provided by different positions of the mask. More driving information for users.
