SK6812/LC8812B 4020 SIDE LED
  • SK6812 SIDE is a smart LED control circuit and light emitting circuit in one controlled LED source,
    which has the shape of a 4020 LED chip. Each lighting element is a pixel, and the intensities of the
    pixels are contained within the intelligent digital interface input. The output is driven by patented PWM
    technology, which effectively guarantees high consistency of the color of the pixels. The control
    circuit consists of a signal shaping amplification circuit, a built-in constant current circuit, and a high
    precision RC oscillator.
    The data protocol being used is unipolar NRZ communication mode. The 24-bit data is transmitted
    from the controller to DIN of the first element, and if it is accepted it is extracted pixel to pixel. After an
    internal data latch, the remaining data is passed through the internal amplification circuit and sent out
    on the DO port to the remaining pixels. The pixel is reset after the end of DIN. Using automatic
    shaping forwarding technology makes the number of cascaded pixels without signal transmission only
    limited by signal transmission speed.
    The LED has a low driving voltage (which allows for environmental protection and energy saving),
    high brightness, scattering angle, good consistency, low power, and long life. The control circuit is
    integrated in the LED above.
