[0002] Existing integrated imaging 3D displays cannot extend beyond the display screen's range, thus limiting their application scenarios. To increase the display range, this invention proposes a super-field-of-view display device based on high-order integrated imaging. This display device incorporates a reflective surface and an innovative integrated imaging method to allow the stereoscopic image range to exceed the screen's limitations. First, it calculates the on-screen and off-screen stereoscopic image pixel arrays using dual-channel integrated imaging. Then, it further limits the projection directions of the on-screen and off-screen stereoscopic image pixel arrays using an aperture limiting function, allowing the on-screen and off-screen stereoscopic images to be displayed via the screen itself and their mirror images on the reflective surface, respectively. The aperture function itself is also an expression of the image pixel array of the viewing area, thus constituting high-order integrated imaging. Finally, the mirror image on the reflective surface allows the stereoscopic image range to exceed the screen's limitations. Summary of the Invention

[0022] This ultra-wide field-of-view display device based on high-order integrated imaging comprises an image element array 100, a two-dimensional beam splitter, and a reflective surface 300; the two-dimensional beam splitter is constructed from a lens array 200. The image element array 100 and the lens array 200 constitute the on-screen display, while their mirror images in the reflective surface 300 constitute the off-screen display. The viewer's eye 500 can see a stereoscopic image 400, with the upper half of the stereoscopic image 400 directly presented by the on-screen display and the lower half presented by the off-screen display. Because the stereoscopic image 400 extends beyond the on-screen display area, an ultra-wide field-of-view display is formed.

[0023] Image element array 100, lens array 200, and reflective surface 300 are placed sequentially from back to front; image element array 100 and lens array 200 are parallel to each other, and the reflective surface of lens array 200 is placed at α=70 degrees.

It is a binary matrix with elements taking values ​​of 0 or 1. M 2( x , y ) is the off-screen stereo image aperture constraint function 122, which is a binary matrix with elements taking values ​​of 0 or 1; I 1( x , y )and I 2( x , y The main focus is on the expression of 400-degree stereoscopic images; while M 1( x , y )and M 2( x , y The main focus is on the realization of the beyond-field-of-view function.

Therefore, the viewer can see the stereoscopic image 400 reproduced by the external stereoscopic image pixel array mirror 113 through the lens array mirror 210 through the reflective surface. Since α=70 degrees, the external stereoscopic image pixel array 112 and the on-screen stereoscopic image pixel array 111 form an angle of 140 degrees. (3) For the reproduction process of the on-screen view area, please refer to Figure 4 ,according to This means that in the view area S 1 can be defined by the aperture of the stereoscopic image on the screen, i.e. M 1( x ,y Recording and reproduction; that is, the viewer's viewpoint S Within 1, the lens array 200 can be seen from... M 1( x , y The pixel range defined in the image meta-array; and because , making M 1( x , y ) acts on I 1( x , y ), that is, in the view area S Within 1, the stereoscopic image 400 reproduced by the stereoscopic image pixel array 111 on the screen can be seen through the lens array 200; (4) For the reproduction process of the off-screen view area, please refer to Figure 5 ,according to This means in the view area S' 2 can be defined by the off-screen stereoscopic image aperture function 122, i.e. M 2( x , y Recording and reproducing; that is, within the field of view. S' Within 2, the lens array 200 can be seen from... M 2( x , y The pixel range defined in the image meta-array; further, because S' 2 is the off-screen stereoscopic image viewing area S 2. The image in the reflecting surface 300, i.e., in the viewing area S Inside 2, the reflection surface 300 and lens array 200 can be seen from the inside. M 2( x , y The pixel range defined in the image meta-array; and because , making M 2( x , y ) acts on I 2( x , y ), that is, in the view area S Inside 2, it can be seen through the reflective surface 300 and the lens array 200. I 2( x , y ) Reproduced stereoscopic image 400; (5) Please refer to Figure 3 At this time, in the field of view S 1 and view area S The intersection of 2 SThe stereoscopic image 400 can be seen completely and correctly inside, and the upper half of the stereoscopic image 400 is partially displayed through the on-screen stereoscopic image element array 111, while the lower half is displayed through the off-screen stereoscopic image element array mirror 113, that is, the mirror of the off-screen stereoscopic image element array 112, thus forming a super-field stereoscopic image display. (6) , , and Substitution It can be seen that the integrated imaging image element in this invention can be expressed as: , Each of its factors contains two H ( X , Y , Z ) mapping, relative to traditional integrated imaging This invention features single-mapping and high-order mapping characteristics, thereby achieving a super-field-of-view display effect.

[0028] Figure 6 This is another embodiment of an ultra-field-of-view display device based on high-order integrated imaging.

[0029] At this point, the two-dimensional beam splitter is replaced by a vertical one-dimensional beam splitter 201 and a horizontal one-dimensional beam splitter 202, which will achieve ultra-field display based on the exact same principle.

[0030] However, due to the different beam-splitting elements, their corresponding... H ( X , Y , Z The mapping process is different and requires... H ( X , Y , Z The mapping is replaced with a mapping method adapted to the combination of vertical one-dimensional beam splitter 201 and horizontal one-dimensional beam splitter 202.

[0031] In summary, the present invention achieves this through... I 1( x , y Records and reproduces stereoscopic images on the screen, through I 2( x , y Record and reproduce off-screen stereoscopic images, and through M 1( x , y )and M 2( x , y This can make I 1( x ,y )and I 2( x , y It can accurately image through the screen itself and the reflective surface, thereby achieving an ultra-wide field of view display effect.
