Intelligent control LED
integrated light source
1 / 8
http://www.world-semi.com
Features and Benefits
The control circuit and the LED share the only power source.
Control circuit and RGB chip are integrated in a package of 5050 components, to form a complete addressable
pixel.
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.
Each pixel of the three primary color can achieve 256 brightness display, completed 16777216 color full color
display, and scan frequency is of 2KHz.
Cascading port transmission signal by single line.
Any two point the distance not more than 3m transmission signal without any increase circuit.
When the refresh rate is 30fps, cascade number are not less than 1024 pixels.
Send data at speeds of 800Kbps.
The color of the light is highly consistent, cost-effective..
Applications
Full-color module, Full color soft lights a lamp strip.
LED decorative lighting, Indoor/outdoor LED video irregular screen.
General description
WS2812B is a intelligent control LED light source that the control circuit and RGB chip are integrated in a package
of 5050 components. It internal include 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 color height consistent.
The data transfer protocol use single NZR communication mode. After the pixel power-on reset, the DIN port receive
data from controller, the first pixel collect 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 24bit. pixel adopt auto reshaping transmit technology, making the pixel
cascade number is not limited the signal transmission, only depend on the speed of signal transmission.
RESET time>280μs , it won't cause wrong reset while interruption, it supports the lower frequency and inexpensive
MCU.
Refresh Frequency updates to 2KHz, Low Frame Frequency and No Flicker appear in HD Video Camera, it improve
excellent display effect.
LED with low driving voltage, environmental protection and energy saving, high brightness, scattering angle is large,
good consistency, low power, long life and other advantages. The control chip integrated in LED above becoming more
simple circuit, small volume, convenient installation.
