DETAILED DESCRIPTION

For more detailed understanding of characteristics and technical contents of embodiments of the present disclosure, the implementation of the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings, and the accompanying drawings are used for reference only, instead of limiting the embodiments of the present disclosure.

Embodiments of the present disclosure provide a 3D display device, comprising a multi-viewpoint 3D display screen (such as: a multi-viewpoint naked-eye 3D display screen), a posture detection apparatus, a 3D signal interface, and a 3D processing apparatus. The 3D display device has a plurality of viewpoints, and has viewpoints corresponding to postures based on the postures of the 3D display device.

The multi-viewpoint 3D display screen comprises a plurality of composite pixels and a plurality of spherical gratings. Each composite pixel comprises a plurality of composite subpixels. The plurality of composite subpixels are covered by the plurality of spherical gratings. In some embodiments, the composite subpixels and the spherical gratings are arranged in one-to-one correspondence. Each composite subpixel comprises a plurality of subpixels, for example, comprises a plurality of subpixels in the form of i×j array. In some embodiments, each composite subpixel comprises a plurality of homochromatic subpixels in the form of i×j array. In some embodiments, subpixels in the i×j array or homochromatic subpixels in the i×j array correspond to i first posture viewpoints in a first posture of the 3D display device and j second posture viewpoints in a second posture of the 3D display device. In some embodiments, i≥3, and j>3. The multi-viewpoint 3D display screen may define a first posture playing region of the 3D display device in the first posture and a second posture playing region of the 3D display device in a second posture. The first posture playing region and the second posture playing region may be the same or different, or overlapped in positions.

The posture detection apparatus is configured to detect a posture of the 3D display device, comprising: detecting a posture change of the 3D display device, or detecting a posture in which the 3D display device is, or detecting the both. The 3D signal interface is configured to receive 3D signals.

The 3D processing apparatus is configured to adjust the display of a 3D image based on the posture of the 3D display device or the posture change of the 3D display device or the both, so that a display orientation of the 3D image is kept in an initial display orientation before the posture change of the 3D display device. Thus, the display orientation of the 3D image may always be consistent with an orientation of the user.

In some embodiments, the 3D processing apparatus processes 3D signals to play the 3D images from 3D contents in the first posture playing region and the 3D images from the 3D contents in the second posture playing region. As for the user, display orientations of the 3D images played in the first posture playing region and the second posture playing region are consistent.

In embodiments of the present disclosure, the “posture” of the 3D display device is equivalent to the “orientation” of the 3D display device.

In some embodiments, the 3D processing apparatus is communicatively connected with the multi-viewpoint 3D display screen. In some embodiments, the 3D processing apparatus is communicatively connected with a driving apparatus of the multi-viewpoint 3D display screen. In some embodiments, the 3D processing apparatus is communicatively connected with the posture detection apparatus.

FIG. 1A shows a 3D display device 100 according to embodiments of the present disclosure. As shown in FIG. 1A, the 3D display device 100 comprises a multi-viewpoint 3D display screen 110, a 3D processing apparatus 130, a 3D signal interface (e.g., a video signal interface 140) configured to receive video frames of 3D signals such as 3D video signals, a processor 120, and a posture detection apparatus 180. In an embodiment shown in FIG. 1A, the multi-viewpoint 3D display screen 110 may comprise a display panel and gratings covering the display panel. The display panel may comprise m columns and n rows (m×n) of composite pixels and thus define a display resolution of m×n.

In some embodiments, each composite pixel comprises red composite subpixels composed of red subpixels in the i×j array, blue composite subpixels composed of blue subpixels in the i×j array, and green composite subpixels composed of green subpixels in the i×j array. FIG. 1A shows an example of a red composite subpixel 410 composed of red subpixels in the i×j array.

In embodiments of the present disclosure, each composite subpixel has corresponding subpixels corresponding to viewpoints. The plurality of subpixels of each composite subpixel are arranged in rows in a transverse direction of the multi-viewpoint 3D display screen; and colors of the plurality of subpixels in rows are the same. Because the multiple viewpoints of the 3D display device are roughly arranged along the transverse direction of the multi-viewpoint 3D display screen, when the user moves to make eyes be in different viewpoints, different subpixels, corresponding to the corresponding viewpoints, in each composite subpixel need to be rendered dynamically. Because the homochromatic subpixels of each composite subpixel are arranged in rows, a cross-color problem caused by persistence of vision can be avoided. In addition, due to refraction of the grating, a part of currently displayed subpixels may be seen at an adjacent viewpoint. However, through arrangement of subpixels with the same color in the same row, a problem of color mixing is absent even if a part of the currently displayed subpixels are seen.

In some embodiments, the gratings comprise a plurality of spherical gratings, and each composite subpixel in the display panel is covered by a corresponding spherical grating. FIG. 2 illustrates the correspondence between a red composite subpixel 410 and a spherical grating 190. The gratings may be composed of a plurality of spherical gratings 190 arranged in an array, and each spherical grating 190 covers a corresponding composite subpixel. Although FIG. 2 shows a spherical grating with a square bottom surface and a circular arc top surface, other configurations of the spherical grating are conceivable. For example, the bottom surface of the spherical grating may be rectangular or hexagonal. For another example, the top surface of the spherical grating may be a circular arc surface or an elliptical arc surface. For another example, the top surface of the spherical grating is directly bonded to the bottom surface. For another example, other planes are connected between the top surface and the bottom surface of the spherical grating; and as shown in FIG. 2, four cross-sectional planes are defined between the circular arc top surface and the square bottom surface of the spherical grating 190.

In some embodiments, the top surface of the spherical grating is provided with another refractive layer with a refractive index different from that of the spherical grating; a surface, facing the spherical grating, of the another refractive layer is bonded with the top surface of the spherical grating in a concave-convex matching manner; and the surface facing away from the spherical grating is a plane, such as a plane parallel to the bottom surface of the spherical grating.

In some embodiments, the 3D display device 100 may be a mobile terminal. Referring to FIGS. 3A and 3B, examples of the posture (orientation) of the 3D display device 100 in the form of mobile terminal are shown. As shown in figures, the 3D display device 100 has a first posture (see FIG. 3A) such as a transverse screen display posture and a second posture (see FIG. 3B) such as a vertical screen display posture. The 3D display device 100 may be switched between the first posture and the second posture. The multi-viewpoint 3D display screen 110 defines a first posture playing region 171 adapted to the first posture and a second posture playing region 172 adapted to the second posture. In the illustrated embodiments, the first posture playing region 171 and the second posture playing region 172 have different dimensions. The area of the first posture playing region 171, for example, may account for 80% to 100% of the area of the multi-viewpoint 3D display screen. The area of the second posture playing region 172, for example, may account for 30% to 60% of the area of the multi-viewpoint 3D display screen. When the 3D display device is in the second posture, the second posture playing region 172, for example, may be located in the middle of the multi-viewpoint 3D display screen.

The 3D display device 100 may have i first posture viewpoints Vi corresponding to the first posture, and have j second posture viewpoints Vj corresponding to the second posture. Correspondingly, the homochromatic subpixels in the i×j array of each composite subpixel correspond to i first posture viewpoints of the 3D display device in the first posture and correspond to j second posture viewpoints of the 3D display device in the second posture. In embodiments shown in FIGS. 3A and 3B, the 3D display device 100 has six first posture viewpoints Vi1-Vi6, and three second posture viewpoints Vj1-Vj3; and the subpixels of each composite subpixel are arranged in the form of 6×3 array. The figures illustrate only the correspondence between the red subpixels in the i×j array of one red composite subpixel 410 and the viewpoints in two postures. In the illustrated embodiments, i=6 and j=3; and conceivably, i and j are other values equal to or greater than 3, respectively.

Conceivably, the composite subpixels and the subpixels may have other suitable shapes. In some embodiments, each composite subpixel is roughly square; i=j is satisfied in the homochromatic subpixels in the i×j array of each composite subpixel; and the aspect ratio of each subpixel is roughly equal to 1. In some embodiments, each composite subpixel is rectangular; each subpixel of each composite subpixel is square or roughly square; and i/j is equal to the aspect ratio of the display panel.

In some embodiments, composite subpixels in different colors are alternately arranged in the display panel; and the plurality of composite subpixels of each composite pixel are arranged in a triangle. As shown in FIG. 4, in the display panel, red composite subpixels 410, green composite subpixels 420, and blue composite subpixels 430 are alternately arranged; and the red composite subpixels 410, the green composite subpixels 420 and the blue composite subpixels 430 of each composite pixel 400 are arranged in a triangle.
