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
