[0032] The fiber optic bundle optical device 101 has a rectangular light-receiving surface at the bottom.

[0033] The display screen 102 is arranged at the bottom of the fiber optic bundle optical device 101.

[0034] The naked-eye 3D display device provided by the present utility model. Through the arranged fiber optic bundle optical device 101, the design of the fiber optic bundle optical device 101 causes the light to bend when passing through the fiber optic bundle optical device 101. This physical phenomenon directly results in the image output by the display screen 102 presenting a more three-dimensional effect visually, enabling the animation or image content to transcend the planar limitation of the traditional screen visually, enhancing the immersion and vividness of viewing.

[0035] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0036] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0037] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0038] Embodiment 1 of the naked-eye 3D display device of the present utility model

[0039] The naked-eye 3D display device of the present utility model includes:

[0040] Please refer to Figures 2 - 5 , the fiber optic bundle optical device 101, and the fiber optic bundle optical device 101 has a rectangular light-receiving surface at the bottom.

[0041] The display screen 102 is arranged at the bottom of the fiber optic bundle optical device 101; in this application, by setting the fiber optic bundle optical device 101, the design of the fiber optic bundle optical device 101 enables the light to bend when passing through the fiber optic bundle optical device 101. This physical phenomenon directly causes the image output by the display screen 102 to present a more three-dimensional effect visually, making the animation or image content break through the planar limitation of the traditional screen visually, enhancing the immersion and vividness of viewing. Compared with the traditional 3D display technology, the naked-eye 3D display device of this application can achieve an ideal 3D display effect without additional complex optical elements or projection devices, which reduces the production cost to a certain extent and greatly improves the convenience and comfort of use;

[0042] The rectangular light-receiving surface has a high degree of fit with the display screen 102, which can ensure that light enters the fiber optic bundle optical device 101 from the display screen 102 evenly and stably. This design can minimize the scattering and loss of light and improve the utilization rate of light. At the same time, the rectangular light-receiving surface matches the common shape of the display screen 102, making the structure of the whole device more compact and reasonable, facilitating installation and use. In addition, the good fit also helps to improve the clarity and stability of the display, bringing a better visual experience to users. The reason is that the rectangular shape is relatively regular and has a high degree of fit with the shape of the display screen 102, which is conducive to the stable entry of light from the display screen 102 into the fiber optic bundle optical device 101, reducing the light loss and scattering caused by shape mismatch.

[0043] Furthermore, as Figure 4 shown, the fiber optic bundle optical device 101 is triangular, and the top of the fiber optic bundle optical device 101 is a rectangular light-emitting surface. The triangular design has good optical properties and can better control the propagation direction and angle of light, making the outgoing light more uniform and stable. The rectangular light-emitting surface can ensure the coverage range and brightness uniformity of the outgoing light, improving the quality and clarity of the image. This design can also increase the aesthetic and technological sense of the device, making it more attractive. The design of the rectangular light-emitting surface matches the shape of common display devices, facilitating viewing and use by users.

[0044] Furthermore, the fiber optic bundle optical device 101 is formed by arranging a number of optical fibers with the same diameter in one direction and bonding them into a block. The optical fibers extend from the bottom to two rectangular light-emitting surfaces at the top. The optical fibers with the same diameter are arranged neatly, which can ensure the consistency and stability of light during transmission. The structure bonded into a block enhances the mechanical strength and stability of the fiber optic bundle optical device 101, enabling it to better withstand external pressure and impact. The design of the two rectangular light-emitting surfaces extending from the bottom to the top allows the light to fully cover the entire display area, improving the brightness and uniformity of the display. This is because the optical fibers with the same diameter can reduce the differences in light transmission, ensuring the quality and stability of the light. The structure bonded into a block can increase the strength and stability of the fiber optic bundle optical device 101, preventing the optical fibers from loosening and being damaged during use. The design of the two rectangular light-emitting surfaces can expand the light-emitting range and improve the display effect;

[0045] Furthermore, the display screen 102 is attached to the bottom of the fiber optic bundle optical device 101 through an optical adhesive. The attachment with the optical adhesive makes the connection between the display screen 102 and the fiber optic bundle optical device 101 closer and more secure, reducing light reflection and scattering and improving the light transmission efficiency. At the same time, the optical adhesive also has good light transmittance and heat resistance, which can ensure the stability and reliability of the display screen 102 during long-term use. In addition, the tight attachment can also reduce the entry of dust and moisture, extending the service life of the device. This is because the optical adhesive has good light transmittance, which can tightly connect the display screen 102 and the fiber optic bundle optical device 101, avoiding light reflection and scattering caused by air gaps. At the same time, the heat resistance and stability of the optical adhesive can ensure the normal operation of the display screen 102 in different environments.

[0046] Furthermore, the light emitted by the display screen 102 is bent after passing through the fiber optic bundle optical device 101.

[0047] Embodiment 2 of the naked-eye 3D display device of the present utility model

[0048] Furthermore, the naked-eye 3D display device of the present utility model, as Figures 1 - 5As shown, a transparent protective housing 2 is provided between the outer surface of the display screen 102 and the fiber optic bundle optical device 101. The transparent protective housing 2 is used to assemble the display screen 102 and the fiber optic bundle optical device 101. The transparent protective housing 2 can not only protect the display screen 102 and the fiber optic bundle optical device 101 from external physical damage and dust pollution, but also play a role in fixing and supporting, ensuring the structural stability of the entire device. At the same time, the transparent design does not affect the light transmission and display effect, enabling users to clearly see the 3D image. In addition, the presence of the protective housing 2 also facilitates the assembly and maintenance of the device, improving production efficiency and product reliability because the transparent protective housing 2 can provide a safe working environment for internal components and prevent external factors from damaging them.

[0049] Furthermore, as Figure 3 shown, pattern surfaces 201 are provided on both sides of the bottom of the transparent protective housing 2. The setting of the pattern surfaces 201 adds decorative and artistic elements to the device, making it more beautiful and attractive.

[0050] Furthermore, the border of the display screen 102 is provided with a background pattern, and the pattern surface 201 is provided with a background pattern that matches the background pattern of the border of the display screen 102 to achieve a 3D effect where the animated content visually extends beyond the border of the transparent protective housing 2. The matching background patterns make the animated content visually appear to extend beyond the border, creating a more extensive visual space, enhancing the vividness and immersion of the 3D effect. This design allows users to be more deeply immersed in the display content, improving the viewing pleasure and experience. At the same time, the consistent background patterns also make the overall appearance of the device more coordinated and unified, increasing the aesthetic value of the product.

[0051] Furthermore, the display screen 102 displays animated content in the area outside the border. Since the border background is consistent with the background pattern of the transparent protective housing 2, the animated content visually presents a 3D stereoscopic effect that extends beyond the border of the display screen 102. At the same time, due to the bending of the pattern of the display screen 102 in the fiber optic bundle optical device 101, the vividness of the 3D effect is further enhanced. The display of animated content in the area outside the border, combined with the consistency of the background patterns and the bending of light, greatly enhances the 3D stereoscopic effect and vividness. Users can feel a more real three-dimensional space, enhancing the immersion and attraction of viewing. This innovative design brings new breakthroughs to the naked-eye 3D display technology, providing users with an unprecedented visual experience. At the same time, it also provides more creative inspiration and possibilities for creators in fields such as film and television and games because the combined effect of multiple factors makes the image visually present a stereoscopic effect that extends beyond the border. The animated content outside the border, the consistency of the background patterns, and the bending of light cooperate with each other to jointly create a strong 3D effect, allowing users to feel a more real and shocking visual impact.

[0052] Embodiment III of the autostereoscopic 3D display device of the present utility model

[0053] Furthermore, a coating is provided on the outer surface of the fiber optic bundle optical device 101 in the autostereoscopic 3D display device of the present utility model;

[0054] The coating can be an anti-reflection coating or an anti-reflection enhancement coating;

[0055] Anti-reflection coating: An anti-reflection coating is provided on the fiber optic bundle optical device 101, which can reduce the reflection loss of light on the fiber optic bundle optical device 101, enabling more light to enter the fiber and propagate along the fiber, thereby significantly improving the light transmission efficiency; this coating is usually prepared by physical vapor deposition or chemical vapor deposition methods, and its materials can be silicon oxide, magnesium fluoride, etc., which have the characteristic of low refractive index and can effectively reduce reflection. After being treated with the anti-reflection coating, the fiber can maintain a high transmission efficiency under light of different wavelengths, especially for the light in the specific wavelength range used in the autostereoscopic 3D display device, the effect is more obvious.

[0056] The anti-reflection enhancement coating has a similar function to the anti-reflection coating, but its purpose is more focused on improving the light transmittance in a specific wavelength range. This coating can be customized according to the wavelength of the light emitted by the display screen 102 to ensure that the light can minimize losses when passing through the fiber optic bundle optical device 101 and improve the transmission efficiency.
