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 voltage programmable constant current contol part,effectively
ensuring the pixel point light color height consistent.
The data transfer protocol use single NZR communication mode. Afer the pixel power-on reset, the DIN port receive data from contoller,the first pixel collect initial 24bit data then sent to the internal data latch,the other data which reshaping by the intemal signal reshaping amplification circut sent to the next cascade pixel trough the DO port.Afer transmission for each pixel,the signal to reduce 24bit.pixel adopt auto reshaping transmit tchnology,making the pixel cascade number isnot limited the signal transmission,only depend on the speed of signal transmision.
RESET time>280μs, it won't cause wrong reset while interuption, it supports the lower frequency and inexpensive MCU
Refresh Frequency updatesto 2KHz. Low Frame Frequency and No Flicker appearin HD Video Camera, it improve excelent display effect.
LED with low driving voltage,environmental protection and energy saving, high brightnessscattering angle is large. good consistency.low power,long life and other advantages.The controlchip integrated in LED above becoming more simpe crcuit, small volume, convenient installation.
● 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 completeadressable
pixel.
● Bul-in signal rshaping circuit after wave reshaping to the next driver,ensure wave-form distortion not
accumulats
.
● Built-in electri eset circuit and power lost rset circuit.
● Each pixel of the three primary color can achieve 256 brightness display,completed 1677216 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 5m transmssion 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-ffective.
● No need for external electric components and even the capacitor.
● Full-color module, LED fll-color soft / hard light bar, LED guardrail tube.
● LED decorative lighting, LED Scren, Indoor / outdoor LED video iregular scren, various electromic products, electrical equipment marquee.
