WS2812B is an intelligent control LED light source where the control circuit and RGB chip are integrated into a single package of 5050 components. It internal includes an intelligent digital port data latch and signal reshaping amplification drive circuit. Also, include a precision internal oscillator and a 12V voltage programmable constant current control part, effectively ensuring the pixel point light colour height consistent. The data transfer protocol uses a single NZR communication mode. After the pixel power-on reset, the DIN port receives data from the controller, the first pixel collects the initial 24bit data then sent to the internal data latch, the other data which reshaping by the internal signal reshaping amplification circuit sent to the next cascade pixel through the DO port. After transmission for each pixel，the signal to reduce by 24bit. pixel adopt auto reshaping transmit technology, making the pixel cascade number is not limited to the signal transmission, only depend on the speed of signal transmission. LED with low driving voltage, environmental protection, and energy-saving, high brightness, scattering angle are large, good consistency, low power, long life, and other advantages. The control chip integrated into LED above becoming more simple circuit, small volume, convenient installation
- Control circuit and RGB chip are integrated into a package of 5050 components, form a complete control of pixel point.
- Built-in signal reshaping circuit, after wave reshaping to the next driver, ensure wave-form distortion not accumulate.
- Built-in electric reset circuit and power lost reset circuit. l Each pixel of the three primary colours can achieve a 256 brightness display, completed 16777216 colour full-colour display, and scan frequency not less than 400Hz/s.
- Cascading port transmission signal by a single line.
- Any two points the distance more than 5m transmission signal without any increase circuit.
