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.
