To keep the purposes, technical schemes and advantages of the embodiment of the present application clearer, below in conjunction with the embodiment of the present application In attached drawing, the technical scheme in the embodiment of the application is clearly and completely described, it is clear that described embodiment is Some embodiments of the present application, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art Every other embodiment obtained without making creative work, shall fall in the protection scope of this application.

Referring to FIG. 1, Fig. 1 is a kind of schematic diagram of 3D display system provided by the embodiment of the present application；With reference to Fig. 1 institute Show, which includes: light cube 10, and light cube 10 includes multilayer LED lamp；Controller 20 is inputted for scan control Mode flags symbol is obtained, is accorded with according to mode flags and is determined display pattern and run corresponding display script and export and display signal to drive Dynamic device 30；Wherein, display pattern includes animation mode and type mode；Driver 30, for vertical according to display signal driving light The LED light of side 10, so that the display of light cube 10 two dimension or three-dimensional animation or text.

Specifically, light cube 10 is used as display module, including multilayer LED lamp, under the driving of driver 30, each layer LED Lamp is successively successively lighted or is extinguished to show two-dimensional picture either statically or dynamically, or three-dimensional either statically or dynamically picture. Wherein, in a kind of specific embodiment, light cube 10 includes 8 layers, and every layer includes 64 LED light.

Specifically, in the present embodiment, light cube 10 is by 8 layers with reference to a kind of smooth cubic array coordinate schematic diagram shown in Fig. 2 LED light is constituted, and every layer includes 8*8=64 LED light, to form the light cube 10 being made of 8*8*8=512 LED light.Respectively The interval of layer LED light is consistent, is such as 20 millimeters.In addition, the LED light in light cube 10 can pass through the connection side of layer common-anode Formula connection.Specifically, for every layer of LED light, 8 LED light of row every in every layer can be welded first, every row 8 when welding The cathode of LED light links together, and then the cathode of every row's LED light links together again, to complete the company of every layer of LED light It connects.Further, on this basis, the anode of each layer LED light is linked together, completes the company of LED light in entire light cube 10 It connects.

Core of the controller 20 as 3D display system, being mainly responsible for scan control input, (control input can specifically pass through Press the button to obtain) mode flags symbol is obtained, it is accorded with according to mode flags and determines display pattern and to run corresponding display script defeated Driver 30 is displayed signal to out；Wherein, display pattern includes animation mode and type mode, and even mode flags symbol corresponds to Animation mode then runs animation script, and light cube 10 is made to show animation；If mode flags symbol corresponds to type mode, run Text script makes light cube 10 show text.

Wherein, in a kind of specific embodiment, controller 20 is specifically as follows single-chip microcontroller, is such as specially to have encryption The good, strong antijamming capability of property is integrated with the advantages such as highly reliable reset circuit, processing speed are fast, memory is abundant STC12C5A60S2 single-chip microcontroller.In addition, equipped with relevant peripheral tandem circuit, and internal clock circuit can be specifically used, it is internal Oscillator generates self-oscillation and provides clock signal.22.1184MHZ can be selected in quartz crystal oscillator.

In addition, controller 20 is also used to receive speed signal and according to speed signal in a kind of specific embodiment Control the display speed of light cube 10.In addition, controller 20 is also used to receive luminance signal in a kind of specific embodiment And the display brightness of light cube 10 is controlled according to luminance signal.Wherein, speed signal, luminance signal can be defeated by corresponding key Enter, thus, realize that light cube 10 shows that the speed of animation or text and brightness are adjustable.

Driver 30 is used for the LED light according to display signal driving light cube 10, so that light cube 10 shows animation or text Word.Specifically, driver 30 drives LED light to light in such a way that layer scans, the feelings of 8 layers of LED light are set in light cube 10 Under condition, scanning 8 layers of LED light is a cycle.Driver 30 lights first layer LED light first, then extinguishes the first LED light simultaneously Second layer LED light is lighted, second layer LED light is extinguished and lights third layer LED light ... so circulation, utilizes the persistence of vision of people special Property, as long as layer scan frequency is higher than critical flicker frequency, i.e. layer scan frequency is higher than 50Hz, just can make it is seen that whole two The display effect of dimension or three-dimensional.

Wherein, in a kind of specific embodiment, driver 30 may include that 74HC595 latch and APM4953 drive Dynamic chip；74HC595 latch, the LED light in Z-direction for driving light cube 10；APM4953 driving chip, for driving LED light on the X/Y plane of dynamic light cube 10.

Specifically, being adapted to light cube 10 includes the case where 8*8*8=512 LED light, 74HC595 latch setting 8 A, APM4953 driving chip is arranged 4.74HC595 latch is a kind of COMS device of silicon structure, the TTL of compatible low-voltage Circuit, serial signal input, parallel signal output, for controlling column driving, the i.e. LED light of driving light cube 10 in z-direction. It sets that there are two individual P-channel COMS to manage inside APM4953 driving chip, there are ultralow on-resistance characteristics, durability is good, High reliablity drives for layer, i.e. LED light on the X/Y plane of driving light cube 10.APM4953 driving chip control 8 is defeated Outlet only needs two SPI string lines, can effectively save I/O interface resource.

Refering to what is shown in Fig. 3, the G1 pin of APM4953 driving chip connect single-chip microcontroller, S1 pin and S2 pin with G2 pin Power supply is connected, as power input.Two D1 pins connect the common-anode of one layer of LED light after being connected, two D2 pins are connected The common-anode of one layer of LED light is connected afterwards.
