General Description
SK6812RGBY is a smart LED control circuit and light emitting
circuit in one controlled LED source, which has the shape of a 5050
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 32-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.
