Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

The structure of a kind of three-dimensional LED lamp display of the utility model is shown in Figure 1, comprises single-chip microcomputer 1, driver 2, latch 3 and LED lamp system 4, and single-chip microcomputer 1 is connected with driver 2 and latch 3 respectively, and LED lamp system 4 are connected with driver 2 and latch 3 respectively.

The microcontroller 1 is an enhanced 8051 microcontroller STC12C5A60S2; the driver 2 is an eight-way NPN Darlington driver ULN2803; the latch 3 is an octal three-state non-inverting transparent latch 74HC573; the structure of the LED lamp system 4 is shown in Figure 2 , which is an 8*8*8 cube structure composed of 512 LED lamps; the cathodes of each layer of LED lamps in the LED lamp system 4 are connected together, and the anodes of each bundle of LED lamps are connected together.

The working principle of the present utility model is that since the cathodes of each layer of LED lamps in the LED lamp system 4 are connected together, the anodes of each bundle of LED lamps are connected together, therefore, each layer of LED lamps in the LED lamp system 4 has a There are 8 common cathode pins in total; the anode side of the LED lamp system 4 has 64 anode pins. The 8 cathode pins are connected to the corresponding output terminals of the driver 2, and the 64 anode pins are connected to the corresponding output terminals of the latch 3 every group of 8. Each layer and each bundle are controlled through the latch 3 and a group of I/O ports of the microcontroller 1 (this group of I/O ports are connected to the driver 2), so that each LED lamp can be controlled independently.

During the working process, the single-chip microcomputer 1 is controlled by computer software, so that the P0 port of the single-chip microcomputer 1 outputs high and low levels to the input terminal of the latch 3, the P2 port outputs high and low levels to the latch terminal of the latch 3, and the P3 port outputs the current Give drive 2. When the latch enable is high, the latch 3 synchronously latches the output input data; when the latch enable is low, the latch 3 will latch the data that meets the setup time and hold time. The P3 port of the single chip microcomputer 1 has a relatively small output current, and the driver 2 amplifies the current and provides it to the LED lamp system 4 to drive the LED lamp. In this way, by changing the high and low levels of each LED light, the on and off of the LED lights can be controlled to form different patterns, and then form dynamic graphics, giving people a three-dimensional feeling.
