The data protocol adopts the communication mode of unipolar return-to-zero code. After powering on and resetting the pixel, the DIN terminal receives the data sent by the controller. First, the transmitted 24-bit data is extracted by the first pixel and then sent to the data latch inside the pixel. After being shaped and amplified by the internal shaping circuit, the remaining data is transmitted to the next cascaded pixel through the DO port, and each pixel signal is reduced by 24 bits. Pixels adopt automatic shaping and forwarding technology, so that the number of cascaded pixels is not limited by signal transmission, but only by signal transmission speed requirements.
LED has the advantages of low voltage driving, environmental protection and energy saving, high brightness, large scattering angle, good consistency, ultra-low power and long life. Integrating the control circuit on the LED makes the circuit simpler, smaller and easier to install.
