Embodiment Construction
[0017] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.
[0018] Such as Figures 1 to 3 As shown, the volumetric three-dimensional display device without a fixed display screen includes a base 1, a rotating component and an intelligent mobile device. The rotating parts include a turntable 21 , a dovetail groove 22 , a fixed clip 23 , a movable clip 24 and a motor for driving the turntable 21 to rotate. The turntable 21 is a circular plate-shaped structure with a rotating shaft extending downward from the center of its bottom surface. The turntable 21 is rotatably connected to t...

The invention discloses a body three-dimensional display apparatus free from a fixed display screen. The apparatus comprises a base, a rotation part and intelligent mobile devices. The rotation part comprises a rotation disk, a motor for driving the rotation disk to rotate and a clamping part. The rotation disk is rotationally arranged on the base through a thrust bearing, the motor is arranged inside the base, the clamping part is fixedly arranged on the rotation disk, the clamping part can clamp the intelligent mobile devices with different-sized display screens, the intelligent mobile devices are internally provided with display control programs, and the programs can display different images according to the rotating speeds of the intelligent mobile devices. The body three-dimensional display apparatus is a real three-dimensional display apparatus, i.e., real three-dimensional images can be seen without application of other auxiliary tools. The display portion of the apparatus is the display screens of such mobile devices as mobile phones, Pads and the like, and the display control programs are preinstalled on the devices such as the mobile phones, the Pads and the like and are controlled by CPUs of these devices.
Description
technical field [0001] The invention relates to the field of three-dimensional image display. More specifically, it relates to a volumetric three-dimensional display device without a fixed display screen. Background technique [0002] As we all know, the display world we live in is a three-dimensional space, so only a three-dimensional display can truly reproduce the objective world, showing the depth, layering and realism of the image. Currently, there are three main types of 3D display technologies: stereoscopic 3D display, volumetric 3D display, and holographic 3D display. Holographic three-dimensional display is still difficult to realize at the current technical level due to the large mass data transmission and storage. Stereoscopic three-dimensional display is based on the principle of stereoscopic vision of people's binocular double-screen, and displays three-dimensional effects with the help of equipment such as glasses. However, this way of expression does not ha...
