SK6812/LC8812B 5050 RGB LED Chip
SK6812/LC8812B is a set of smart control circuit and a light emitting circuit in
one of the controlled LED source. The outer type is the same with a
5050LED chip, each element is a pixel. Pixels contained within the
intelligent digital interface data latch signal shaping amplification circuit,
power supply circuit, a built-in constant current circuit, high precision
RC oscillator, the output is driven by the patented PWM technology,
effectively guarantee the pixels in the color of the light high consistency.
Data protocol using unipolar NRZ communication mode, the pixel is
reset after the end of DIN, accept the data transmitted from the
controller to the 24bit, the first to send data by the first pixel to pixel
extraction, internal data latch, the remaining data after the internal
plastic the processing circuit after shaping amplification through the
DO port output began to turn to the next cascade of pixels, each pixel
through a transmission signal, reduce. Pixel using automatic shaping
forwarding technology, makes the number of cascade without signal
transmission limit of the pixel, only limited signal transmission speed.
LED has a low driving voltage, environmental protection and energy
saving, high brightness, scattering angle, good consistency, low power,
long life and so on. The control circuit is integrated in the LED above,
more simple circuit, small volume, easy installation.
  • Main Application Field:

    ● Full color LED string light, LED full color module, LED super hard and soft lights,

    LED guardrail tube, LED appearance / scene lighting

    ● LED point light, LED pixel screen, LED shaped screen, a variety of electronic products,

    electrical equipment etc..

    Mechanical Product Size (unit mm):
    ● Top SMD internal integrated high quality external control line serial cascade constant current IC;

    ● control circuit and the RGB chip in SMD 5050 components, to form a complete control of pixel,

    color mixing uniformity and consistency;

    ●built-in data shaping circuit, a pixel signal is received after wave shaping and output waveform

    distortion will not guarantee a line;

    ●The built-in power on reset and reset circuit, the power does not work;
    ●gray level adjusting circuit (256 level gray scale adjustable);
    ● red drive special treatment, color balance;
    ● line data transmission;

    ● plastic forward strengthening technology, the transmission distance between two points over


    ●data transmission frequency up to 800Kbps, when the refresh rate of 30 frames per second,

    a cascade of not less than 1024;

    ● built-in powerpolarity protection module, powerpolarity will not damage.
