1. General description

LC8812B is a external controlled intelligent LED with control circuit and light emitting circuit in one 5050 components. Each LED is a pixel, The pixel contains the intelligent digital interface data latch signal shaping amplifier driving circuit, power supply voltage regulator circuit, built-in constant current circuit, high precision RC oscillator, and the output driver adopts patented PWM technology, which Effectively ensure that the color of each pixel is consistent

The data protocol being used is unipolar NRZ communication mode. After the pixel power-on reset, the DIN port receive data from controller,When the frist 24-bit data is extracted by the first pixel and sent to Data latch which inside the pixel ,The remaining data is processed by the internal shaping circuit, The remaining data is shaped and amplified by the internal shaping processing circuit, and then the output is forwarded to the next cascaded pixel through the DO port. The Data transmission through each pixel, the signal will reduce 24bit , The pixel is reset after the end of DIN. Using automaticshaping forwarding technology makes the number of cascaded pixels without signal transmission, only limited by signal transmission speed.

The LED has alow driving voltage, environmental protection and energy saving,high brightness, scattering angle, good consistency, low power, and long lifespan . The control circuit is integrated in the LED ,which make Components smaller and more easier to install.

2.   Applications

l Full-color module, Flexible led Strip ,Rigid led strip

l LED decorative lighting, LED Panel a variety of electronic products, electrical equipment etc

3. Main Feature

● SMD internal integrated high quality external control line serial cascade constant current IC;

● Control circuit and the RGB chip integrated in SMD 5050 components, to form a  complete external control pixel, make the color mix 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;

● Gray level adjusting circuit (256 level gray scale adjustable);

● Red drive special treatment, color balance;

● Single-line data transmission for unlimited cascade

● Plastic forward strengthening technology, the transmission distance between two points over 10M;

● Data transmission frequency can reach 800 Kbps, when the refresh rate of 30 frames per sec,the number of cascades is not less than 1024 points.
