WS2812C is an intelligent control LED light source, its exterior
adopts the latest MOLDING packaging technology, the control circuit
and RGB chips are integrated in a package of 2020 component. Its
internal includes intelligent digital port data latch and signal
reshaping amplification drive circuit. Also include a precision
internal oscillator and a 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, large scattering angle, good consistency,
low power, long life and other advantages. The control chip
integrated in LED above becoming more simple circuit, small volume,
convenient installation.
Features and Benefits
● The control integrated circuit and the LED share the only power
source.
● 5mA operating current per channel.
● Control circuit and RGB chip are integrated in a package of 2020
componens, to form a complete addressble pixel.
● Built-in signal reshaping circuit,after wave reshaping to the
next driver,ensure wave-fom distortion not
accumulate.
Built-in
electric reset circuit and powerlost ese circuit.
● Each pixel of the tree primary color can achieve 256 brightness
display,completed 16777216 color ful color
display, and scan
frequency is of 2KHz.
● Cascading port transmission signal by single line.
● Any two point the distance not more than 5m transmission signal
without any increase circuit
● When the refresh rate is 30fps,cascade number are not less than
1024 pixels.
