Description

Technical Field

[0001] The present invention relates to the field of display technologies, and particularly to a display device and a display method for a display device. Background Art

[0002] Three-dimensional (3D) stereoscopic display technology is considered the future development direction of display technologies and has gradually become a development trend in the field of display technologies. Current 3D stereoscopic display technologies are divided into four categories: spectroscopic stereoscopic glasses, auto-stereoscopic display, holography, and volumetric 3D display.

[0003] Among them, both spectroscopic stereoscopic glasses and auto-stereoscopic display use the method of parallax (i.e., the left and right eyes respectively display slightly different images, thus deceiving the brain and making the observer have a sense of 3D stereoscopic display) to give people a sense of 3D stereoscopic display. However, since the 3D stereoscopic scene constructed by the method of artificially creating parallax is not natural, the use of the parallax method to achieve 3D stereoscopic display increases the mental burden of the observer, and can cause headaches for viewers when watching the display content for a long time. Holography uses the interference and diffraction of light waves to achieve 3D stereoscopic display, but the current development progress is very slow. Volumetric 3D display uses the persistence of vision effect to achieve 3D stereoscopic display. Compared with spectroscopic stereoscopic glasses, auto-stereoscopic display, and holography, volumetric 3D display can achieve a true dynamic 3D stereoscopic display effect. However, static volumetric 3D display has high costs and a short lifespan, is not suitable for commercial use, and the imaging space is directly related to the physical volume, so miniaturized design cannot be achieved. Scanning volumetric 3D technology uses a mechanical method to achieve imaging in the third dimension. Therefore, the combination of multiple mechanical movements brings greater instability and also occupies a relatively large physical volume, limiting the actual application scenarios of scanning volumetric 3D technology. Therefore, how to develop a universal 3D stereoscopic display device has become the key to the development in the display field. Summary of the Invention

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. In addition, it should be understood that the specific implementation manners described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise stated, the orientation terms such as "upper" and "lower" generally refer to the upper and lower in the actual use or working state of the device, specifically the drawing direction in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0034] Specifically, as Figure 1 is a system block diagram of a display device provided by the present invention. As Figures 2A - 2B is a schematic structural diagram of a display device provided by an embodiment of the present invention; An embodiment of the present invention provides a display device, including a driving module and a display module.

[0035] The driving module includes a driving mechanism 101 and a rotating mechanism 102. The driving mechanism 101 is rotatably connected to the rotating mechanism 102 to drive the rotating mechanism 102 to perform a rotational motion around the axis CA.

[0036] The display module includes a plurality of display components 201 and a plurality of optical components 202. The plurality of display components 201 and the plurality of optical components 202 are both installed on the rotating mechanism 102 to rotate coaxially with the rotating mechanism 102. Each optical component 202 is located on the corresponding display component 201 and is inclined with respect to the display component 201.

[0037] Among them, the plurality of optical components 202 are used to project the light emitted by the corresponding display components 201 into the imaging space outside the rotating mechanism 102. The rotating mechanism 102 is used to drive the plurality of optical components 202 and the plurality of display components 201 to perform a rotational motion, so that the light projected into the imaging space through the plurality of optical components 202 forms a multi-layer two-dimensional image Pi in the imaging space. The superposition of the multi-layer two-dimensional images Pi forms a three-dimensional image to present a true three-dimensional floating display effect.

[0038] Optionally, the driving mechanism 101 includes devices such as a motor.

[0039] Optionally, the rotating mechanism 102 includes a rotating bracket 1021 and a rotating shaft 1022. The central axis of the rotating bracket 1021 coincides with the axis CA, and the rotating shaft 1022 is installed at the central axis of the rotating bracket 1021.

[0040] Optionally, the rotating bracket 1021 and the rotating shaft 1022 can be integrally formed. Optionally, the rotating bracket 1021 and the rotating shaft 1022 are connected by means of threads, grooves and protrusions, keys, pins, etc. Optionally, a reliable connection is achieved between the rotating bracket 1021 and the rotating shaft 1022 through interference fit.

[0041] A plurality of the display components 201 are arranged around the central axis CA of the rotating bracket 1021 and installed on the rotating bracket 1021. A plurality of the optical components 202 are arranged around the central axis CA of the rotating bracket 1021 and installed between the rotating bracket 1021 and the rotating shaft 1022, so that each of the optical components 202 is inclined with respect to the central axis CA and the corresponding display component 201.

[0042] By making each of the optical components 202 inclined with respect to the central axis CA and the corresponding display component 201, the plurality of optical components 202 can project the light emitted by the corresponding display component 201 into the imaging space outside the rotating bracket 1021. Thus, when the rotating mechanism 102 drives the plurality of optical components 202 and the plurality of display components 201 installed on the rotating bracket 1021 to perform a rotational movement, the light projected into the imaging space by the plurality of optical components 202 forms multiple two-dimensional images Pi in the imaging space, and the superposition of the multiple two-dimensional images Pi forms a stereoscopic image, so as to present a true three-dimensional floating display effect.

[0043] Optionally, the plurality of optical components 202 and the plurality of display components 201 are in one-to-one correspondence, so that the light emitted by each display component 201 is projected into the imaging space outside the rotating bracket 1021 through the corresponding optical component 202, and a layer of two-dimensional image Pi is formed under the drive of the rotating mechanism 102.

[0044] Optionally, a first connecting portion is provided at one end of each optical component 202 connected to the rotating shaft 1022, and the first connecting portion is connected to the rotating shaft 1022. Optionally, the first connecting portion is in a circular ring shape to be sleeved on the rotating shaft 1022.

[0045] Optionally, a plurality of first grooves are provided on the rotating bracket 1021, and a protrusion corresponding to the first groove may be provided at one end of each optical component 202 connected to the rotating bracket 1021 to realize the connection between the optical component 202 and the rotating bracket 1021. Optionally, the rotating bracket 1021 and the optical component 202 may also be connected by means of threads, keys, pins, etc.

[0046] Optionally, each display component 201 may be mounted on the rotating bracket 1021 by means of glue, threads, keys, pins, etc. Optionally, a plurality of second grooves are provided on the rotating bracket 1021, and the plurality of display components 201 are correspondingly located in the second grooves.

[0047] Optionally, the rotating bracket 1021 has a first support surface 1021a, the rotating shaft 1022 is perpendicular to the first support surface 1021a, and the plurality of display components 201 are located within the first support surface 1021a. Wherein, in order to enable the light emitted by each display component 201 to be projected into the imaging space by the corresponding optical component 202, the sum of the areas of the plurality of display components 201 is less than or equal to the area of the first support surface 1021a, so that the light emitted by the plurality of display components 201 is not blocked by each other, ensuring that the light emitted by each display component 201 can be projected into the imaging space by the corresponding optical component 202, thereby forming the two-dimensional image Pi in the imaging space.

[0048] Optionally, the first support surface 1021a is circular. In addition, the first support surface 1021a may also be polygonal, elliptical, etc.

[0049] As Figures 3A - 3C is a schematic structural diagram of the display component provided by the embodiment of the present invention. Optionally, the display module further includes a plurality of display brackets 203, the plurality of display brackets 203 are mounted on the rotating bracket 1021, and the plurality of display components 201 are mounted on the plurality of display brackets 203, so that the plurality of display components 201 are mounted on the rotating bracket 1021 through the plurality of display brackets 203.

[0050] Optionally, please continue to refer to Figure 3A , the center of each display bracket 203 overlaps with the central axis of the rotating bracket 1021, and two display components 201 are provided on opposite sides of the center of each display bracket 203.

[0051] Optionally, the rotation axis 1022 passes through the center of each of the display brackets 203, so that the center of each of the display brackets 203 overlaps with the central axis of the rotary bracket 1021. Optionally, an opening is provided at the center of each of the display brackets 203, and the rotation axis 1022 passes through the opening and is fixedly connected to each of the display brackets 203, so as to drive the plurality of display brackets 203 to rotate when the rotation axis 1022 rotates.

[0052] By arranging the two display components 201 on the opposite sides of the center of one of the display brackets 203, one of the display brackets 203 can correspond to the two optical components 202, thereby saving the number of the display brackets 203.

[0053] Optionally, the first support surface 1021a is circular. When the plurality of display components 201 are mounted on the rotary bracket 1021 in such a form that the display components 201 are arranged on the opposite sides of the center of one of the display brackets 203, the number n of the display brackets 203 included in the display module is < πd 2 / 4LW, and n≥1; where n is the number of the display brackets 203 included in the display module, d is the diameter of the first support surface 1021a, L is the length of each of the display brackets 203, and W is the width of each of the display brackets 203, so that the sum of the areas of the plurality of display components 201 is less than or equal to the area of the first support surface 1021a.

[0054] Since each of the display components 201 has a corresponding optical component 202, when the number n of the display brackets 203 included in the display module is 1, the display module includes two display components 201. Correspondingly, the display module also includes the optical components corresponding to the two display components 201. Therefore, when the light emitted by the two display components 201 is projected into the imaging space through the corresponding optical components 202, a multi-layer two-dimensional image can be formed, and thus a three-dimensional stereoscopic image is formed by superimposing the multi-layer two-dimensional images.

[0055] Optionally, the diameter d of the first support surface 1021a can be greater than or equal to the length L of the display bracket 203, so that when the display bracket 203 is mounted on the rotary bracket 1021, the display bracket 203 is always located within the first support surface 1021a.

[0056] Optionally, please continue to refer to Figure 3B , a plurality of display brackets 203 are mounted between the rotary bracket 1021 and the rotation axis 1022, and each of the display brackets 203 is provided with one display component 201.

[0057] Optionally, one end of each of the display brackets 203 connected to the rotating shaft 1022 is provided with a second connecting portion, and the second connecting portion is connected to the rotating shaft 1022. Optionally, the second connecting portion is in an annular shape to be sleeved on the rotating shaft 1022.

[0058] Optionally, the first support surface 1021a is circular. When a plurality of the display components 201 are all mounted on the rotating bracket 1021 in such a form that one display component 201 is provided on one display bracket 203, the number n of the display brackets 203 included in the display module is < πd 2 / 4PW, and n≥2; where n is the number of the display brackets 203 included in the display module, d is the diameter of the first support surface 1021a, P is the length of each display bracket 203, and W is the width of each display bracket 203, so that the sum of the areas of a plurality of the display components 201 is less than or equal to the area of the first support surface 1021a.

[0059] Optionally, the diameter d of the first support surface 1021a is greater than or equal to twice the length P of the display bracket 203 (i.e., d≥2P), so as to prevent the sum of the lengths of two display brackets 203 located on the same extension line from being greater than the diameter d of the first support surface 1021a, so that a plurality of the display brackets 203 can be located within the first support surface 1021a.

[0060] Optionally, the display module may include an even number of the display components 201 or may include an odd number of the display components 201. Optionally, when the display module includes an even number of the display components 201, it can be realized by a setting method in which two display components 201 are provided on one display bracket 203. Optionally, when the display module includes an odd number of the display components 201, it can be realized by a setting method in which two display components 201 are provided on one display bracket 203 in cooperation with a setting method in which one display component 201 is provided on one display bracket 203, or can be realized by separately adopting a setting method in which one display component 201 is provided on one display bracket 203.

[0061] Optionally, each display bracket 203 can be mounted on the rotating bracket 1021 by connection methods such as glue, thread, key, pin, etc. Optionally, each display bracket 203 can also be disposed in a plurality of second grooves on the rotating bracket 1021.

[0062] Please continue to refer to Figure 3C, the distance from the center of each of the display components 201 to the central axis of the rotating bracket 1021 may be unequal, so as to change the distance of each of the display components 201 relative to the axis CA, thereby changing the spatial position of the two-dimensional image Pi projected into the imaging space by the light emitted by the corresponding display component 201 through the corresponding optical component 202.

[0063] Optionally, the distances from the axis CA to the ends 201a of the plurality of display components 201 close to the axis CA are unequal, so that when the light emitted by the display components 201 is projected into the imaging space through the optical components 202, the distances of the two-dimensional images Pi formed by the light projected into the imaging space driven by the rotating mechanism from the axis CA are unequal. Wherein, the distance from the axis CA to the two-dimensional image Pi formed by the light emitted by each of the display components 201 projected into the imaging space through the corresponding optical component 202 is equal to the sum of the distance Ln from the axis CA to the end 201a of the display component 201 close to the axis CA and the length Ld of the display component 201.

[0064] During imaging, the plurality of display components 201 and the plurality of optical components 202 continuously perform rotational motion driven by the rotating mechanism 102. Each of the display components 201 displays different contents at different positions and is projected into the imaging space through the corresponding optical component 202, and the corresponding projection depth is the sum of the distance Ln from the axis CA to the end 201a of the display component 201 close to the axis CA and the length Ld of the display component 201. By virtue of the persistence of vision effect, the different contents displayed by the plurality of display components 201 at different positions are projected into the imaging space through the corresponding optical components 202 and will be presented as a continuous circular suspended image, and then a plurality of the two-dimensional images Pi are formed. Due to the different spatial depths of the two-dimensional images Pi generated by different display components 201, when viewing the display device, multiple layers of the two-dimensional images Pi will be superimposed, thereby forming a complete suspended three-dimensional image.

[0065] It can be understood that in the depth direction of the imaging space, the distance of each layer of the two-dimensional image Pi from the axis CA can be set according to actual needs.

[0066] Optionally, to make the multiple two-dimensional images Pi generated by the projection of the multiple display components 201 through the multiple optical components 202 be evenly arranged in the depth direction within the imaging space, the distances from the axis CA to one ends 201a of the multiple display components 201 close to the axis CA are in equal proportion. It can be understood that in some special display requirements, the distances from the axis CA to one ends 201a of the multiple display components 201 close to the axis CA may not be designed in equal proportion.

[0067] Optionally, the distances from each display component 201 to the central axis of the rotary bracket 1021 can be equal. When the distances from each display component 201 to the central axis of the rotary bracket 1021 are all equal, the parameters of the multiple optical components 202 and the angles between the optical components 202 and the corresponding display components 201 can be adjusted to adjust the distances from the multiple two-dimensional images Pi projected by the multiple display components 201 through the multiple optical components 202 into the imaging space to the rotary axis 1022.

[0068] Please continue to refer to Figures 3A - 3C , each display component 201 includes a plurality of light-emitting devices D, and the plurality of light-emitting devices D are arranged in a staggered manner. Among them, the distances from the plurality of light-emitting devices D of the plurality of display components 201 to the axis CA are all unequal, so that when the plurality of display components 201 make the rotational movement along with the rotating mechanism 102, the movement trajectories of the plurality of light-emitting devices D in each display component 201 do not overlap, and the movement trajectories of the plurality of light-emitting devices D in the plurality of display components 201 do not overlap. Therefore, when the plurality of display components 201 make the rotational movement along with the rotating mechanism 102, the light emitted by the plurality of display components 201 can be projected into the imaging space through the corresponding optical components 202, and the vacancies without the projection of the light-emitting units can be mutually supplemented, so that the resolution of the display device can be further improved under the limitation of the existing process conditions.

[0069] Optionally, the light-emitting device D includes a light-emitting diode, a liquid crystal display module, etc. Optionally, the light-emitting device includes an organic light-emitting diode, a submillimeter light-emitting diode, a micro light-emitting diode, a quantum dot light-emitting diode, etc. Optionally, the colors of the light emitted by the plurality of light-emitting devices D include red, green, blue, white, yellow, etc.

[0070] Optionally, the optical component 202 includes a transmissive suspension device, a reflective suspension device, a reverse suspension device, etc. Optionally, the optical component 202 includes a negative reflection lens, a cross-reflection array, etc. A plurality of the optical components 202 are configured to project the light emitted by the plurality of display components 201 to different positions within the imaging space.

[0071] As Figure 4 FIG. is a schematic structural diagram of the optical component provided by an embodiment of the present invention. Each of the optical components 202 has an incident light surface 202a and an outgoing light surface 202b that are oppositely arranged.
