Description

Technical Field

[0001] The present disclosure relates to the field of virtual reality playback equipment, and in particular to a stereoscopic display device arranged on the ground. Background Art

[0002] Stereoscopic display technology can make images appear realistic, giving users an immersive feeling. Naked-eye stereoscopic display technology, which allows users to see 3D images without the need for special glasses, is widely used in outdoor advertising, entertainment activities, scenic spots, education, and commercial exhibitions.

[0003] Currently, stereoscopic display technology generally uses multiple interconnected display screens to display images, with adjacent display screens being perpendicular or nearly perpendicular to each other, so that users can view images with a stereoscopic effect from a specific viewing angle.

[0004] However, in order to increase the service life of the display, in the above-mentioned prior art, users are usually required to maintain a certain distance from the display screen to reduce damage to the display screen. For example, the display screen is set on the wall of a building so that users cannot interact with or directly touch the display screen at close range, which greatly reduces the user experience. Summary of the Invention

[0005] The present disclosure is made in view of the above-mentioned state of the prior art, and its purpose is to provide a stereoscopic display device disposed on the ground that is convenient for close interaction with a user.

[0006] To this end, the present disclosure provides a stereoscopic display device arranged on the ground, comprising a first display unit arranged on the ground, a second display unit connected to the first display unit, and a processing unit, wherein the second display unit is at least partially higher than the ground; the first display unit comprises a shell forming a accommodating cavity, and a supporting member and a display member arranged in the accommodating cavity, the shell having an opening portion flush with the ground, the supporting member being arranged in the opening portion and above the display member and configured to protect the display member, wherein the supporting member comprises a first supporting layer made of impact-resistant material and a second supporting layer made of pressure-resistant material, the display member being configured to emit light and the light propagating through the supporting member to the opening portion; the processing unit is configured to input stereoscopic picture information into the first display unit and the second display unit, the second display unit having a first preset angle with the first display unit and displaying a stereoscopic picture corresponding to the stereoscopic picture information.

[0007] In the present disclosure, the display member of the first display unit is protected by a support member comprising a first support layer made of an impact-resistant material and a second support layer made of a pressure-resistant material. This makes the first display unit, which is disposed on the ground, less susceptible to damage from impact or pressure from people, animals, or vehicles on the ground. This allows the stereoscopic display device to be positioned close to the user, facilitating close interaction with the user. Furthermore, the resistance to damage of the first display unit extends the service life of the first display unit, thereby improving the durability of the stereoscopic display device and reducing its maintenance costs.

[0008] In addition, in the ground-mounted stereoscopic display device of the present disclosure, the support member may optionally have a light transmittance of no less than 50%. In this case, light emitted by the display member can pass through the support member and be received by the user's eyes. This protects the first display unit and enhances the stereoscopic display effect.

[0009] In addition, the ground-mounted stereoscopic display device of the present disclosure may optionally further include a third display unit that is at least partially elevated above the ground, with a second preset angle between the third display unit and the first display unit, and the first, second, and third display units being interconnected in pairs. In this case, the addition of the third display unit to the first and second display units can enhance the stereoscopic display effect of the stereoscopic display device.

[0010] In addition, in the stereoscopic display device set on the ground involved in the present disclosure, optionally, it also includes a first sensing unit, which is set on the second display unit and / or the third display unit and is configured to sense a light signal, and the processing unit is configured to receive a first signal related to the light signal, and in response to the change amount of the first signal being greater than a first preset value and the change amount being a decrease, the brightness of the stereoscopic picture is reduced, and in response to the change amount being greater than the first preset value and the change amount being an increase, the brightness of the stereoscopic picture is increased. In this case, it is possible to detect the light in the surrounding environment of the stereoscopic display device and adaptively adjust the brightness of the stereoscopic display device according to the change of the light. When the light in the surrounding environment of the stereoscopic display device becomes brighter, the brightness of the stereoscopic picture can be increased, which can improve the visibility of the stereoscopic picture when the light in the surrounding environment is strong, thereby reducing the fatigue of the user's eyes. As a result, the stereoscopic display effect can be maintained when the light in the surrounding environment of the stereoscopic display device changes; when the light in the surrounding environment becomes darker, the brightness of the stereoscopic display device is reduced, which can reduce energy consumption; in addition, by adjusting the brightness of the stereoscopic picture in response to the change in the first signal being greater than the first preset value, it is possible to reduce the situation where the brightness of the stereoscopic picture is frequently adjusted due to slight changes in the light in the surrounding environment.

[0011] In addition, in the stereoscopic display device disposed on the ground as disclosed herein, optionally, when the amount of change is a decrease, the adjustment amount of the first display unit is the smallest, and when the amount of change is an increase, the adjustment amount of the first display unit is the largest. In this case, since the light emitted by the display component of the first display unit may be blocked (for example, the support component may block the light emitted by the display component), the brightness displayed by the display component is smaller than that of other display units. By reducing the brightness of the first display unit less than that of other display units when the detected first signal decreases, and increasing the brightness of the first display unit more than that of other display units when the detected first signal increases, the stereoscopic display effect of the stereoscopic display device can be improved, allowing the user to view a more realistic stereoscopic image.

[0012] In addition, in the stereoscopic display device set on the ground involved in the present disclosure, optionally, it also includes a second sensing unit, which is set on the first display unit and configured to sense a pressure signal, and the processing unit is configured to receive a second signal related to the pressure signal, and adjust the virtual viewing angle of the stereoscopic image in response to the second signal, wherein the signal value of the second signal is positively correlated with the virtual viewing angle. In this case, the virtual viewing angle of the stereoscopic image is adjusted by the pressure signal. When the pressure signal is associated with the type of user, it is convenient to adaptively adjust the virtual viewing angle according to the type of user, so that the adjusted virtual viewing angle matches the user's viewing angle, thereby enabling the user to obtain a good stereoscopic visual effect.

[0013] In addition, in the stereoscopic display device set on the ground involved in the present disclosure, optionally, an adjustment unit is further included, wherein the adjustment unit is configured to adjust the angle between the second display unit and the first display unit, and the processing unit is configured to update the stereoscopic picture information in response to a change in the angle between the second display unit and the first display unit. In this case, by updating the stereoscopic picture information according to the angle between the second display unit and the first display unit, the stereoscopic display effect can be maintained when the angle changes. In addition, by adjusting the angle between the second display unit and the first display unit through the adjustment unit, the stereoscopic display device can be adapted to different needs. For example, adjusting the angle so that the second display unit overlaps with the first display unit can facilitate the storage of the stereoscopic display device.

[0014] In addition, in the ground-mounted stereoscopic display device of the present disclosure, optionally, gaps are formed between the support member and the display member and the sidewalls of the housing, and the gaps are filled with waterproof glue. In this case, the waterproof glue can provide a certain degree of waterproofness for the stereoscopic display device, thereby reducing the risk of damage to the stereoscopic display device due to water ingress.

[0015] In addition, the ground-mounted stereoscopic display device of the present disclosure may optionally further include a photovoltaic unit configured to provide electrical energy to the stereoscopic display device and comprising a solar panel configured to convert light energy into electrical energy and a battery unit configured to receive and store electrical energy from the solar panel. This can reduce energy consumption.

[0016] In addition, in the 3D display device provided on the ground as disclosed herein, the inner surface of the housing may optionally be provided with a shock-absorbing layer made of a damping material. In this case, providing the shock-absorbing layer on the inner surface of the housing can reduce the impact of vibrations on the 3D display device, making the 3D display device suitable for use in environments where the ground may vibrate to a certain extent (e.g., outdoors, where there is a lot of traffic).

[0017] According to the present disclosure, a stereoscopic display device disposed on the ground is provided to facilitate close interaction with a user. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The preferred embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. In the following description, identical components are assigned identical reference numerals, and duplicate descriptions are omitted. In addition, the accompanying drawings are merely schematic, and the proportions of the dimensions of the components and the shapes of the components may differ from the actual ones.

[0029] It should be noted that the terms "including" and "having" and any variations thereof in this disclosure, such as a process, method, system, product or device that includes or has a series of steps or units, are not necessarily limited to those steps or units clearly listed, but may include or have other steps or units that are not clearly listed or are inherent to these processes, methods, products or devices.

[0030] It should be noted that the relative position and relative direction terms such as "above", "towards above", "below", "towards downward", "up and down direction", "left side", "towards the left side", "left direction", "towards the left", "right side", "towards the right side", "right side", "towards the right", "left and right direction", "front", "towards the front", "back", "towards the back", "front and back direction" in this document refer to the normal operating posture and should not be considered as restrictive.

[0031] The present disclosure relates to a ground-mounted stereoscopic display device (also referred to as a 3D display device or a naked-eye 3D display device). The stereoscopic display device of the present disclosure is suitable for use in high-traffic outdoor environments, such as those with people, animals, or vehicles passing by. The stereoscopic display device of the present disclosure is also suitable for use in high-traffic indoor environments. The stereoscopic display device provided by the present disclosure facilitates close-range interaction with users.

[0032] The present disclosure relates to an object disposed on the ground, which may be an object disposed so as to at least partially be in direct contact with the ground.

[0033] The stereoscopic images disclosed herein can be formed by selecting a specific virtual perspective after three-dimensional modeling. The virtual perspective can simulate the user's viewing angle when the stereoscopic display device generates the stereoscopic image information. When the stereoscopic display device displays the stereoscopic image, the user can view the stereoscopic image from a perspective corresponding to the virtual perspective. The stereoscopic image can be altered by adjusting the virtual perspective. After the virtual perspective of the stereoscopic image is adjusted, the user needs to adjust the viewing angle to achieve a good stereoscopic visual effect.

[0034] Hereinafter, the stereoscopic display device involved in the present disclosure will be described in detail with reference to the accompanying drawings.

[0035] Figure 1 2 is a diagram showing an application scenario of the stereoscopic display device 2 involved in the example of the present disclosure.

[0036] For some examples, see Figure 1 A stereoscopic display device 2 can be set on a floor 1. The floor 1 can be outdoors or indoors. People, animals, or vehicles can pass over the floor 1. When passing over the floor 1, the people, animals, or vehicles can contact the stereoscopic display device 2 and apply pressure. In some examples, the stereoscopic display device 2 can display a stereoscopic image. Users can view the stereoscopic image with a stereoscopic display effect without wearing additional equipment.

[0037] Figure 2 1 is a schematic diagram showing a first embodiment of a stereoscopic display device 2 according to an example of the present disclosure.

[0038] For some examples, see Figure 2 , the stereoscopic display device 2 may include a display unit 21 and a processing unit 22 ( Figure 2 (not shown). The display unit 21 may include a first display unit 210 and a second display unit 220. That is, the number of the display units 21 may be plural.

[0039] For some examples, see Figure 2 , the first display unit 210 can be set on the ground 1. The upper surface of the first display unit 210 can be parallel or almost parallel to the ground 1. The upper surface of the first display unit 210 can be flush with the ground 1. In other examples, the upper surface of the first display unit 210 can be higher than the ground 1.

[0040] For some examples, see Figure 2 , the second display unit 220 can be connected to the first display unit 210. Specifically, the second display unit 220 can be structurally connected to the first display unit 210. In some examples, the second display unit 220 can also be electrically connected to the first display unit 210.

[0041] For some examples, see Figure 2The second display unit 220 may be at least partially elevated above the ground 1. For example, the second display unit 220 may be vertically positioned above the ground 1, or may be tilted above the ground 1. The angle between the second display unit 220 and the first display unit 210 may be equal to the angle between the second display unit 220 and the ground 1. The second display unit 220 and the first display unit 210 may have a first preset angle. In some examples, the first preset angle is not equal to 0 degrees and 180 degrees. In some examples, the first preset angle may be between 70 degrees and 110 degrees. Preferably, the first preset angle may be 90 degrees. In other words, the second display unit 220 is perpendicular to the first display unit 210. The second display unit 220 is perpendicular to the ground 1. In this case, a stereoscopic image can be displayed using the first display unit 210 positioned above the ground 1 and the second display unit 220, which is at least partially elevated above the ground 1 and has the first preset angle relative to the first display unit 210.

[0042] In some examples, the first display unit 210 may include an LED display, an LCD display, or an OLED display. In some examples, the second display unit 220 may include an LED display, an LCD display, or an OLED display.

[0043] Figure 3 1 is a schematic diagram showing a second embodiment of the stereoscopic display device 2 according to the present disclosure example.

[0044] For other examples, see Figure 3 , the display unit 21 may include only the first display unit 210. The first display unit 210 may include a first display portion 230 disposed parallel to and above the ground 1, and a second display portion 240 at least partially above the ground 1. That is, the first display unit 210 and the second display unit 220 may be the same display unit 21. The first display unit 210 may include a flexible display screen. That is, the first display portion 230 and the second display portion 240 may be flexibly connected. In this case, the display of the connection portion between the first display portion 230 and the second display portion 240 can be optimized, thereby improving the stereoscopic display effect.

[0045] In some examples, the processing unit 22 can be configured to input stereoscopic image information into the first display unit 210 and the second display unit 220. In some examples, the processing unit 22 can store the stereoscopic image information. The processing unit 22 can generate a stereoscopic model. Based on the stereoscopic model, the processing unit 22 can select a virtual perspective to generate the stereoscopic image information. The stereoscopic image information can be an analog signal or a digital signal that causes the display unit 21 to display the stereoscopic image. After selecting different virtual perspectives, the user can view the stereoscopic images displayed by the first display unit 210 and the second display unit 220 from the corresponding perspectives.

[0046] In some examples, the second display unit 220 has a first preset angle with the first display unit 210 and displays a stereoscopic image corresponding to the stereoscopic image information. The second display unit 220 and the first display unit 210 can receive the stereoscopic image information and display the corresponding stereoscopic image.

[0047] In some examples, the processing unit 22 can be disposed below the ground 1. For example, the processing unit 22 can be disposed in a portion of the first display unit 210 that is below the ground 1. In this case, the processing unit 22 can be protected. In some examples, the processing unit 22 can be connected to the display unit 21 by wire or wirelessly.

[0048] Figure 4 1 is a schematic diagram showing a third embodiment of the stereoscopic display device 2 according to the present disclosure example.

[0049] For some examples, see Figure 4 , the stereoscopic display device 2 may further include a third display unit 250. That is, the display unit 21 may further include a third display unit 250. The third display unit 250 may be at least partially higher than the ground 1. For example, the third display unit 250 stands above the ground 1, is vertically disposed above the ground 1, or is tilted above the ground 1. The angle between the third display unit 250 and the first display unit 210 may be equal to the angle between the third display unit 250 and the ground 1. The third display unit 250 may have a second preset angle with the first display unit 210. In some examples, the second preset angle may be between 70 degrees and 110 degrees. Preferably, the second preset angle may be 90 degrees. In this case, by adding the third display unit 250 to the first display unit 210 and the second display unit 220, the stereoscopic display effect of the stereoscopic display device 2 can be enhanced.

[0050] For some examples, see Figure 4, the third display unit 250 can be connected to the first display unit 210. Specifically, the third display unit 250 can be structurally connected to the first display unit 210. In some examples, the third display unit 250 can also be electrically connected to the first display unit 210. In some examples, the first display unit 210, the second display unit 220, and the third display unit 250 can be interconnected in pairs. Specifically, the first display unit 210, the second display unit 220, and the third display unit 250 can be structurally connected to each other in pairs. In some examples, the first display unit 210, the second display unit 220, and the third display unit 250 can be electrically connected in pairs.

[0051] In some examples, the third display unit 250 may include an LED display, an LCD display, or an OLED display.

[0052] In some examples, the processing unit 22 may be configured to input stereoscopic picture information to the first display unit 210 , the second display unit 220 , and the third display unit 250 to display a stereoscopic picture.

[0053] Figure 5 FIG. 2 is a cross-sectional view showing the first display unit 210 according to an example of the present disclosure. Figure 6 2 is an exploded schematic diagram showing the first display unit 210 involved in the example of the present disclosure.

[0054] For some examples, see Figure 5 and Figure 6 , the first display unit 210 may include a housing 211 , a display member 212 , and a support member 213 .

[0055] For some examples, see Figure 5 and Figure 6 The housing 211 may be rectangular. The housing 211 may be formed with a receiving cavity 214. In some examples, the housing 211 may have an opening 215. The opening 215 may face the ground 1. The opening 215 may be flush with the ground 1.

[0056] In some examples, the housing 211 can be made of a metal material, such as aluminum alloy or stainless steel. In this case, the metal material can provide the housing 211 with sufficient strength to support the support member 213 and the display member 212 in the accommodating cavity 214. Furthermore, the metal material has excellent thermal conductivity, allowing it to dissipate heat generated by the display member 212.

[0057] For some examples, see Figure 5 and Figure 6The display member 212 can be disposed in the receiving cavity 214. That is, the display member 212 can be disposed within the first display unit 210. The display member 212 can be an LED display, an LCD display, or an OLED display. The display member 212 can be configured to emit light. In some examples, the light can be transmitted through the support member 213 to the opening 215.

[0058] For some examples, see Figure 5 and Figure 6 , the support member 213 can be arranged in the accommodating cavity 214. That is, the support member 213 can be arranged inside the first display unit 210. The support member 213 can be arranged in the opening 215. The support member 213 can be located above the display member 212. The support member 213 can be configured to protect the display member 212. The support member 213 can be configured to come into contact with a person, an animal, or a vehicle and withstand pressure. In this case, the support member 213 located above the display member 212 and the housing 211 carrying the display member 212 can reduce damage to the display member 212.

[0059] For some examples, see Figure 5 The support member 213 and the display member 212 can each form a gap 216 with the sidewalls of the housing 211. In some examples, the gap 216 can be filled with waterproof glue. In other words, the support member 213 and the display member 212 are fixed to the accommodating cavity 214 using the waterproof glue. In this case, the waterproof glue can provide a certain degree of waterproof performance for the stereoscopic display device 2, reducing the possibility of damage to the stereoscopic display device 2 due to water ingress.

[0060] In some examples, a gap 216 may be formed between the support member 213 and the display member 212. In this case, the waterproof glue can flow into the gap 216 between the support member 213 and the display member 212, thereby further fixing the support member 213 and the display member 212.

[0061] In some examples, the waterproof adhesive can be made of a light-transmitting material. In some examples, the light transmittance of the waterproof adhesive can be no less than 50%. In this case, light emitted by the display member 212 can pass through the waterproof adhesive and be received by the user's eyes. This protects the first display unit 210 and enhances the stereoscopic display effect.

[0062] For some examples, see Figure 5 and Figure 6The inner surface of the housing 211 may be provided with a shock-resistant layer 2110 made of a damping material. In this case, by providing the shock-resistant layer 2110 on the inner surface of the housing 211, the impact of vibrations on the stereoscopic display device 2 can be reduced, making the stereoscopic display device 2 suitable for environments where the ground 1 may vibrate to a certain extent (for example, outdoors and other places with a lot of traffic).

[0063] Figure 7A 1 is an exploded schematic diagram showing a first embodiment of a support member 213 according to an example of the present disclosure.

[0064] For some examples, see Figure 7A , the support member 213 may be in the shape of a flat plate. The support member 213 may be made of a pressure-resistant and impact-resistant material. In some examples, see Figure 7A , the support member 213 may include a first support layer 217 and a second support layer 218. In this case, the protection effect of the display member 212 can be improved by the multi-layer support layer.

[0065] In some examples, the support member 213 can be made of a light-transmitting material. In some examples, the light transmittance of the support member 213 is not less than 50%. In this case, light emitted by the display member 212 can pass through the support member 213 and be received by the user's eyes. This can protect the first display unit 210 and enhance the stereoscopic display effect.

[0066] In some examples, the first support layer 217 can be made of an impact-resistant material. In some examples, the first support layer 217 can have impact resistance. In some examples, the second support layer 218 can be made of a pressure-resistant material. In some examples, the second support layer 218 can have pressure resistance. In this case, by protecting the display member 212 of the first display unit 210 with the support member 213 including the first support layer 217 made of an impact-resistant material and the second support layer 218 made of a pressure-resistant material, the first display unit 210 disposed on the ground 1 can be less susceptible to damage when subjected to impact or pressure. This allows the stereoscopic display device 2 to be positioned close to the user, facilitating close interaction with the user. Furthermore, the resistance to damage of the first display unit 210 can extend the service life of the first display unit 210, thereby improving the durability of the stereoscopic display device 2 and reducing the maintenance cost of the stereoscopic display device 2. This makes the stereoscopic display device 2 suitable for use on a ground 1 with high traffic volume.

[0067] In some examples, the impact-resistant material may be polycarbonate, polymethyl methacrylate, or polyoxymethylene. In some examples, the impact-resistant material is preferably polycarbonate. In some examples, the pressure-resistant material may be tempered glass. That is, the first support layer 217 and the second support layer 218 are polycarbonate and tempered glass, respectively. The first support layer 217 can be arranged near the ground 1, and the second support layer 218 can be arranged farther from the ground 1 than the first support layer 217. In other words, the first support layer 217 can be arranged above the second support layer 218. In this case, the support member 213 can have both impact resistance and pressure resistance. In addition, by placing the tempered glass below the polycarbonate, the polycarbonate can protect the tempered glass, thereby reducing the possibility of the tempered glass breaking when impacted.

[0068] In some examples, the second display unit 220 may include a first support layer 217 made of an impact-resistant material and a second support layer 218 made of a pressure-resistant material. The first support layer 217 and the second support layer 218 may be disposed on the outer surface of the second display unit 220. In this case, the first support layer 217 and the second support layer 218 disposed on the outer surface of the second display unit 220 can protect the display screen inside the second display unit 220, reducing the risk of damage to the portion of the second display unit 220 above the ground 1 due to impact or pressure.

[0069] Figure 7B 1 is an exploded schematic diagram showing a second embodiment of the support member 213 according to the example of the present disclosure.

[0070] For some examples, see Figure 7B The support member 213 may further include a third support layer 219. The third support layer 219 may be disposed below the second support layer 218. The third support layer 219 may be made of an impact-resistant material. That is, the support member 213 may comprise, in sequence, a first support layer 217 made of an impact-resistant material, a second support layer 218 made of a pressure-resistant material, and a third support layer 219 made of an impact-resistant material. In this case, the impact resistance of the support member 213 may be further improved, thereby further protecting the display member 212 and the second support layer 218.

[0071] Figure 8 2 is a system block diagram showing a stereoscopic display device 2 according to an example of the present disclosure.

[0072] For some examples, see Figure 8The stereoscopic display device 2 may include a sensing unit 23. The sensing unit 23 may include a first sensing unit 231. The first sensing unit 231 may be a light sensor. For example, the first sensing unit 231 may be a photoresistor, a photocapacitor, or a phototransistor. The first sensing unit 231 may be configured to sense a light signal. The first sensing unit 231 may convert the sensed light signal into a first signal. The first signal may be an electrical signal. In this case, the light signal sensed by the first sensing unit 231 may be used to obtain the intensity of light in the surrounding environment of the stereoscopic display device 2.

[0073] In some examples, the first sensing unit 231 may be disposed on the display unit 21 that is at least partially above the ground 1. The first sensing unit 231 may also be disposed on the second display unit 220 and / or the third display unit 250. In this case, the light intensity of the surrounding environment in the direction of the user's viewing angle can be obtained through the light signal sensed by the first sensing unit 231 disposed on the display unit 21 that is at least partially above the ground 1.

[0074] In some examples, the processing unit 22 can be configured to receive a first signal related to the light signal. In some examples, the processing unit 22 can adjust the brightness in response to the change in the first signal. The change in the first signal can be an increase or decrease in the magnitude of the first signal. In some examples, the processing unit 22 can reduce the brightness of the stereoscopic image in response to the change in the first signal being greater than a first preset value and the change being a decrease. The first preset value can be a pre-set size of the change. In some examples, the processing unit 22 can increase the brightness of the stereoscopic image in response to the change being greater than the first preset value and the change being an increase. That is, when the ambient light of the stereoscopic display device 2 becomes darker and darker by a certain amount, the brightness displayed by the display unit 21 can be reduced. When the ambient light of the stereoscopic display device 2 becomes brighter and brighter by a certain amount, the brightness displayed by the display unit 21 can be increased. In this case, the ambient light around the stereoscopic display device 2 can be detected and the brightness of the stereoscopic display device 2 can be adaptively adjusted based on changes in the ambient light. By increasing the brightness of the stereoscopic image when the ambient light around the stereoscopic display device 2 becomes brighter, the visibility of the stereoscopic image in brighter ambient light can be improved, reducing eye fatigue in the user. This allows the stereoscopic display effect to be maintained even when the ambient light around the stereoscopic display device 2 changes. Furthermore, by reducing the brightness of the stereoscopic display device 2 when the ambient light becomes dim, energy consumption can be reduced. Furthermore, by adjusting the brightness of the stereoscopic image in response to a change in the first signal exceeding a first preset value, frequent adjustments to the brightness of the stereoscopic image due to minor changes in ambient light can be reduced.

[0075] In some examples, when the amount of change is a decrease, the adjustment amount of the first display unit 210 may be the smallest. In some examples, when the amount of change is an increase, the adjustment amount of the first display unit 210 may be the largest. The adjustment amount may be an amount by which the brightness of the display unit 21 is adjusted. In other words, when the ambient light around the stereoscopic display device 2 dims, the brightness of the first display unit 210 decreases less than that of the other display units 21. When the ambient light around the stereoscopic display device 2 brightens, the brightness of the first display unit 210 increases more than that of the other display units 21. In this case, since the light emitted by the display component 212 of the first display unit 210 may be blocked (for example, the supporting component 213 may block the light emitted by the display component 212), the brightness displayed by the display component 212 is lower than the brightness of other display units 21. By reducing the brightness of the first display unit 210 less than that of other display units 21 when the detected first signal decreases, and increasing the brightness of the first display unit 210 more than that of other display units 21 when the detected first signal rises, the stereoscopic display effect of the stereoscopic display device 2 can be improved, and the user can view a more realistic stereoscopic picture.

[0076] For some examples, see Figure 8 , the sensing unit 23 may include a second sensing unit 232. The second sensing unit 232 may include a pressure sensor. The second sensing unit 232 may be configured to sense a pressure signal. The second sensing unit 232 may convert the sensed pressure signal into a second signal. The second signal may be an electrical signal. The second sensing unit 232 may be provided on the first display unit 210. Specifically, when the received pressure signal is large, it may be determined that the user is an adult. When the received pressure signal is small, it may be determined that the user is a child. In this case, the type of user can be determined by the pressure signal.

[0077] In some examples, the processing unit 22 can be configured to receive a second signal related to the pressure signal. In some examples, the processing unit 22 can adjust the virtual viewing angle of the stereoscopic image in response to the second signal. The signal value of the second signal can be positively correlated with the virtual viewing angle. That is, the larger the signal value of the second signal, the higher the virtual viewing angle. Specifically, when the signal value of the second signal is larger, the corresponding pressure signal is larger, and the pressure on the first display unit 210 is greater, it can be determined that the height of the user located on the first display unit 210 is higher, and the corresponding viewing angle is higher, so that the virtual viewing angle of the stereoscopic image can be increased in response to the increase in the second signal. In this case, the virtual viewing angle of the stereoscopic image is adjusted by the pressure signal. When the pressure signal is associated with the type of user, the type of user can be determined based on the second signal, so that the virtual viewing angle is adaptively adjusted according to the type of user, so that the adjusted virtual viewing angle matches the user's viewing angle, thereby enabling the user to obtain a good stereoscopic visual effect.

[0078] In some examples, the second sensing unit 232 may include a pressure sensor array. The pressure sensor array may be provided on the first display unit 210. Specifically, the pressure sensor array may be provided on the support member 213. The pressure sensor array may be provided between the first support layer 217 and the second support layer 218. In some examples, the processing unit 22 may obtain a position signal of the user on the first display unit 210 based on the second signal generated by the pressure sensor array. The processing unit 22 may adjust the virtual viewing angle of the stereoscopic image in response to the position signal and / or pressure signal corresponding to the second signal. In this case, the virtual viewing angle can be adaptively adjusted for the user located on the first display unit 210, thereby enabling the user to obtain a good stereoscopic visual effect.

[0079] In some examples, the second sensing unit 232 can be provided on the second display unit 220 and / or the third display unit 250. The second sensing unit 232 can include a resistive sensor or a capacitive sensor. The processing unit 22 can modify the stereoscopic image information based on the second signal from the second sensing unit 232. In this case, the second sensing unit 232 can obtain user input to the stereoscopic display device 2. This enables the stereoscopic display device 2 to have a touch interaction function.

[0080] In some examples, the sensing unit 23 may include a third sensing unit 233. The third sensing unit 233 may include a pressure sensor. The third sensing unit 233 may include a resistive sensor or a capacitive sensor. The third sensing unit 233 may be configured to sense a pressure signal. The third sensing unit 233 may be provided on the second display unit 220 and / or the third display unit 250. The processing unit 22 may be configured to receive a third signal related to the pressure signal. The processing unit 22 may change the stereoscopic image information based on the third signal from the third sensing unit 233. In this case, the user's input to the stereoscopic display device 2 can be obtained through the third sensing unit 233. Thus, the stereoscopic display device 2 can have a touch interaction function.

[0081] In some examples, the processing unit 22 can change the brightness of the stereoscopic image in response to the second signal being greater than a second preset value and the change in the first signal being greater than a first preset value. In other words, the brightness of the stereoscopic display device 2 is changed when the pressure signal is greater than the second preset value and the light signal changes by at least the first preset value. In other words, the brightness of the stereoscopic display device 2 is changed only when a pressure signal from the user is sensed and the ambient light around the stereoscopic display device 2 changes by a certain amount. In this case, adaptively changing the brightness based on detecting whether a user is viewing the stereoscopic image using the second signal can reduce energy consumption.

[0082] For some examples, see Figure 8 , the stereoscopic display device 2 may include an adjustment unit 26. The adjustment unit 26 may be configured to adjust the angle between the second display unit 220 and the first display unit 210. The adjustment unit 26 may rotate the second display unit 220 to adjust the angle between the second display unit 220 and the first display unit 210. The adjustment unit 26 may rotate the second display unit 220 to overlap with the first display unit 210. That is, the adjustment unit 26 may be foldable. In this case, by updating the stereoscopic picture information according to the angle between the second display unit 220 and the first display unit 210, the stereoscopic display effect can be maintained even when the angle changes. In addition, by adjusting the angle between the second display unit 220 and the first display unit 210 by the adjustment unit 26, the stereoscopic display device 2 can be adapted to different needs. For example, by adjusting the angle by the adjustment unit 26 so that the second display unit 220 overlaps with the first display unit 210, the stereoscopic display device 2 can be easily stored. Furthermore, by adjusting the angle of the second display unit 220 and the first display unit 210 by the adjustment unit 26, the effects of adverse factors such as dust, moisture, and ultraviolet rays on the stereoscopic display device 2 can be reduced. Furthermore, the first display unit 210 includes a pressure-resistant and impact-resistant support member 213, which reduces the possibility of damage to the first display unit 210 caused by the second display unit 220 after the overlap.

[0083] In some examples, the adjustment unit 26 can receive a first signal related to the light signal. In some examples, the adjustment unit 26 can adjust the angle in response to a change in the first signal. In this case, in a strong outdoor light environment, adjusting the angle between the second display unit 220 and the first display unit 210 by the adjustment unit 26 can enable the user to obtain a clear stereoscopic display effect. In addition, compared to adjusting the brightness, adjusting the angle to maintain the stereoscopic display effect in strong light can reduce energy consumption and improve battery life.

[0084] In some examples, the processing unit 22 can be configured to update the stereoscopic image information in response to a change in the angle between the second display unit 220 and the first display unit 210. In this case, by updating the stereoscopic image information based on the angle between the second display unit 220 and the first display unit 210, the stereoscopic display effect can be maintained even when the angle changes.

[0085] For some examples, see Figure 8 The stereoscopic display device 2 may include at least one visual unit 27. The visual unit 27 may include a camera. The at least one visual unit 27 may generate a visual signal related to the environment surrounding the stereoscopic display device 2. In this case, an image of the environment surrounding the stereoscopic display device 2 can be obtained through the at least one visual unit 27.

[0086] In some examples, the processing unit 22 can be configured to input the stereoscopic picture information into the first display unit 210 and the second display unit 220 in response to the visual signal of the at least one visual unit 27 to display the stereoscopic picture. Specifically, the processing unit 22 can receive the visual signal and identify the human eye position based on the recognition algorithm, and adjust the virtual viewing angle based on the human eye position. For example, the processing unit 22 can overlap the virtual viewing angle of the stereoscopic picture with the human eye position identified based on the visual signal, and input the stereoscopic picture information after adjusting the virtual viewing angle into the first display unit 210 and the second display unit 220. In this case, by identifying the human eye position in the visual signal and adjusting the virtual viewing angle based on the human eye position, the virtual viewing angle can be adaptively adjusted for the user viewing the stereoscopic display device 2, so that the adjusted virtual viewing angle matches the user's eye position, thereby enabling the user to obtain a good stereoscopic visual effect.

[0087] In some examples, when the processing unit 22 does not recognize a human eye, the first display unit 210 and the second display unit 220 may be turned off. In this case, it is possible to recognize that the stereoscopic display device 2 is not being viewed by anyone and turn off the display unit 21. This can reduce energy consumption.

[0088] In some examples, the processing unit 22 can be configured to input stereoscopic image information into the first display unit 210 and the second display unit 220 to display a stereoscopic image in response to the second signal and the visual signal of at least one visual unit 27. Specifically, the processing unit 22 can receive the visual signal and identify the user's body size based on the recognition algorithm, and determine the viewing angle of the user located on the first display unit 210 in combination with the signal value of the second signal, that is, the size of the pressure signal. When the user's body is thinner and the pressure on the first display unit 210 is greater, it can be determined that the height of the user located on the first display unit 210 is higher, and the corresponding viewing angle is higher, thereby adjusting the corresponding virtual viewing angle in the stereoscopic image information. In this case, by combining the second signal and the visual signal, the accuracy of the adjusted virtual viewing angle can be improved, thereby improving the stereoscopic visual effect.

[0089] For some examples, see Figure 8 The stereoscopic display device 2 may include a photovoltaic unit 28. The photovoltaic unit 28 may be configured to provide electrical energy to the stereoscopic display device 2. In some examples, the photovoltaic unit 28 may include a solar panel and a battery unit. The solar panel may be configured to convert light energy into electrical energy. The battery unit may be configured to receive and store electrical energy from the solar panel. The battery unit may provide electrical energy to the stereoscopic display device 2. This may reduce energy consumption.

[0090] For some examples, see Figure 8The stereoscopic display device 2 may include a status indicator 29. The status indicator 29 may be configured to indicate the operating status of the stereoscopic display device 2. The status indicator 29 may also be configured to transmit the operating status of the stereoscopic display device 2. In this case, maintenance personnel can easily obtain the operating status of the stereoscopic display device 2 through the status indicator 29, thereby improving maintenance efficiency.

[0091] For some examples, see Figure 8 The stereoscopic display device 2 may include a heat dissipation unit 30. The heat dissipation unit 30 may be configured to obtain temperature information of the stereoscopic display device 2. The heat dissipation unit 30 may include a temperature sensor to obtain temperature information. The heat dissipation unit 30 may also be configured to dissipate heat in response to the temperature information. In this case, heat dissipation by the heat dissipation unit 30 can reduce heat accumulation generated during operation of the stereoscopic display device 2.

[0092] In some examples, the first end of the heat dissipation unit 30 can be close to or in contact with the display member 212. The second end of the heat dissipation unit 30 can be in contact with the housing 211 or extend through the housing 211. In this case, the heat generated by the stereoscopic display device 2 can be transferred away through the first and second ends of the heat dissipation unit 30. In addition, the heat transferred from the second end can also dissipate snow or ice on and around the stereoscopic display device 2, thereby protecting the normal operation of the stereoscopic display device 2 and the safety of people or vehicles passing by the stereoscopic display device 2.

[0093] In some examples, the heat dissipation unit 30 may include a refrigerator or a radiator for heat dissipation. The refrigerator may be a semiconductor refrigeration chip. The radiator may be a heat sink or a fan. The radiator may also include a tube for heat conduction and a laminate for heat dissipation.

The display member 212 is configured to emit light, which is transmitted through the support member 213 to the opening 215. The processing unit 22 is configured to input stereoscopic image information into the first display unit 210 and the second display unit 220. The second display unit 220 has a first predetermined angle with the first display unit 210 and displays a stereoscopic image corresponding to the stereoscopic image information. In this case, by protecting the display member 212 of the first display unit 210 with the support member 213 including the first support layer 217 made of an impact-resistant material and the second support layer 218 made of a pressure-resistant material, the first display unit 210, which is disposed on the ground 1, is less susceptible to damage when subjected to impact or pressure from people, animals, vehicles, etc. on the ground 1. This allows the stereoscopic display device 2 to be positioned close to the user, facilitating close interaction with the user. Furthermore, the first display unit 210 is not easily damaged, which can extend the service life of the first display unit 210, thereby improving the durability of the stereoscopic display device 2 and reducing the maintenance cost of the stereoscopic display device 2. Furthermore, the stereoscopic display device 2 can be used on a floor 1 with high foot traffic. Thus, a stereoscopic display effect can be easily achieved on a floor 1 with high foot traffic.
