Description

Double-tangent-plane spherical cylinder panoramic digital RVR naked eye dynamic immersion type display device Technical Field The utility model relates to the technical field of naked eye display, in particular to a double-tangent-plane spherical cylinder panoramic digital RVR naked eye dynamic immersion type display device. Background With the development of Virtual Reality (VR) technology, immersive display devices are increasingly used in educational training, exhibition, and other scenes. However, currently, the mainstream VR devices all rely on helmets, glasses, and other wearable equipment, which results in users facing the following technical bottlenecks: Experience limitations for wearable devices The physiological discomfort is that the weight of the head-mounted equipment is generally more than or equal to 300g, cervical vertebra compression and visual fatigue are easy to be caused when the head-mounted equipment is worn for a long time, for example, the weight of a OculusQuest helmet is 375g, and the dizziness incidence rate of users is more than or equal to 40% after the head-mounted equipment is continuously used for more than 1 hour; The reality is split, namely wearing equipment isolates a user from a real environment, virtual-real fusion experience cannot be achieved, and particularly in a scene requiring limb interaction (such as an offline large-space VR game), the risk of winding equipment cables is high. Although the prior naked eye VR technology attempts to solve the wearing problem, the prior naked eye VR technology has obvious defects: The naked eye 3D display device disclosed by CN210200247U adopts a single cylinder structure, the angle of view is only 270 degrees, and the viewing angle in the vertical direction cannot be covered; The hemispherical display equipment of CN112326189A is limited by the curved surface screen splicing technology, the splicing gap between the upper edge and the lower edge is not less than 1mm, and the image distortion rate is not less than 5%. Defective body structure of display device The space adaptability is insufficient, and the traditional sphere and cylinder display equipment is difficult to balance the field coverage and the installation space requirement. For example, a cylindrical device with a diameter of 3 meters has a horizontal field of view of 360 °, but a vertical field of view of only 180 °, and a 720 degree panorama cannot be achieved; The optical design is lacking in that the existing body structure does not optimize the light reflection path for naked eye display, for example, the naked eye VR device of CN211508548U does not consider the curved screen light refraction angle, and the brightness of the central viewing area is attenuated by 30%. Hysteresis of support and mounting technique The fixing mode is low-efficiency, the traditional support frame is connected by adopting all bolts, such as a display screen fixing structure of CN209844312U, 6 bolts are needed for single-screen installation, the time is more than or equal to 15 minutes, and the maintenance efficiency is low.
