LED display screen is divided into three parts, unit board, power supply and control card. The power supply supplies + 5V voltage to each unit board and connects it to the unit board, but pay attention not to connect the positive and negative poles reversely. A + 5V is led out from the power supply to supply power to the control card, and the control card outputs several data signals to the unit board. The power supply is like a human heart, while the control card is like a human brain.
