Description

Technical Field

[0001] The invention belongs to the field of display technology and relates to a naked-eye 3D device and a use method thereof. Background Art

[0002] With the rapid development of science and technology, 3D display technology has become a hot topic in current research. In many fields such as education, entertainment, medical treatment, industrial design, etc., people's demand for three-dimensional display effects is increasing. However, most of the existing 3D display devices and technologies have some limitations and cannot meet users' comprehensive needs for high quality, convenience, interactivity and stereoscopic effect.

[0003] For example, in traditional teaching equipment, although holographic projection technology can provide a certain degree of three-dimensional display effect, it usually requires additional projection equipment and complex settings, and does not have interactive functions, which limits its application scope in teaching. At the same time, some desk-type teaching equipment attempts to integrate virtual imaging technology, but due to immature technology or poor results, it has not been widely used.

[0004] In addition, although virtual reality technologies such as AR / VR / MR can provide an immersive three-dimensional experience, users usually need to wear head-mounted devices, which not only affects the comfort of use, but also increases the complexity and cost of the equipment. For users who use it for a long time, head-mounted devices may also cause visual fatigue and physical discomfort.

[0005] Although some existing 3D display devices use transparent screen technology, such as transparent OLED screens or transparent Micro LED screens, these devices can only achieve single-screen display and cannot provide a full range of three-dimensional effects. At the same time, since the light-emitting diodes are lit for a long time, they are prone to aging problems, affecting their service life and display effects.

[0006] Therefore, the market is in urgent need of a new type of naked-eye 3D device that can overcome the shortcomings of the existing technology and achieve high-quality naked-eye 3D display effects. Such a device should have the characteristics of convenience, interactivity and strong stereoscopic sense, and be able to meet the needs of users in different scenarios. It is based on this background that the present invention proposes a new type of naked-eye 3D device and its implementation method, aiming to provide a more advanced, practical and efficient 3D display solution. Summary of the invention
