Problems solved by technology

[0004] The current POV technology does not have a specific and mature display screen interaction solution around the display control of LEDs. This is also because the high-speed rotation of the POV technology solution cannot access various traditional two-dimensional interactive sensors, so it is impossible to achieve full-screen complex interactions. , only simple light or radio frequency remote control

Embodiment 1

[0048] Disc POV display interactive system:

[0049] like image 3 As shown, the rotating plate 5 is in the shape of a flat plate, and the rotating plate 5 rotates around an axis perpendicular to the plate in the plane where the plate is located to obtain the disc display effect shown in the figure.

[0050] The base is a transmitting coil 1 with a diameter of 30cm, which operates at 300kHz-1MHz, and transmits 10 watts of power to the receiving coil 3 when the system is working, and the distance between the transmitting and receiving coils is 5-10 cm. The constantly rotating shaft at the center is the rotary drive 2 . In the rotary drive device 2, the motor 21 is a brushless DC motor such as KINGKONG1306 with a working power of 8.2W. The rotary drive device 2 and the rotary plate 5 are welded together. When the rotary drive device 2 rotates, the motor 21 will drive the entire rotary plate 5. rotate.

[0051] According to the principle of persistence of vision, if the speed ...

Embodiment 2

[0057] Spherical three-dimensional POV display interactive system:

[0058] like Figure 4 As shown, the rotating plate 5 is in the shape of an arc plate, and the rotating plate 5 rotates on a spherical surface around an axis perpendicular to the center of the circle where the arc is located to obtain the spherical display effect shown in the figure. And a connecting rod 15 is fixedly installed on the side of the motor 21 body of the rotary driving device 2 , and two receiving coils 3 with smaller diameters are installed in the connecting rod 15 .

[0059] The arrangement of the LEDs is an arc with a diameter of 10 cm, which is composed of 33 patch-type high-brightness LEDs. When the system is working, the LED arc array 14 rotates around the rotation axis 22 to obtain a complete spherical 3D display effect. The LED arc array 14 is installed on the rotating plate 5, and the receiving coil 3 for power supply, the power drive circuit 4, the rotating drive device 2 and the drive ...

Abstract

The invention discloses a POV display interaction method and system. According to the invention, a one-dimensional LED linear array is used for light emitting and light sensation detection. The display effect of a two-dimensional pattern image is obtained through high-speed rotation of a one-dimensional LED linear array. Light sensation input is conducted through a lighting tool, and the one-dimensional LED linear array detects a light sensation signal input by the lighting tool in real time and generates change feedback on the displayed two-dimensional pattern image to achieve light sensationinteraction. Meanwhile, the one-dimensional LED linear array is remotely driven to work by adopting wireless resonance power supply to perform display and interaction functions. The method and the system are low in implementation cost, compact and simple in circuit and wide in application range, and can be applied to various indoor and outdoor display interaction occasions.

Description

technical field [0001] The invention relates to a POV display and interaction method, in particular to a complete POV display and interaction system. Background technique [0002] Persistence of vision (POV) is the short stay of vision. According to medical principles, when the human eye looks at an object, the image of the object will be formed on the retina. The photoreceptor cells on the retina convert light signals into bioelectrical signals and send them to the brain through the optic nerve; however, when the object is removed, the impression of the object on the optic nerve will not disappear immediately, and the specific time will not disappear within about 1 / 24 second , this phenomenon is called persistence of vision. The TV and movies we usually watch use this principle. When the static picture is continuously played at a speed exceeding 24 frames per second, the picture perceived by the human eye is dynamic. [0003] In modern society, most of the most common LE...
