APA104 LED STRIP VS WS2812B LED STRIP
Nowadays ,we have develop a new led strip ,which name APA104 LED strip , some people may have a question about what is the difference between apa104 led strip and our ws2812b led strip , let me discuss about them
Frist,Both of them are 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 curre-nt 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 resha-ping transmit technology, making the pixel cascade number is not limited 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 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.
Second Both of them can achieve 256 brightness display, completed 16777216 color full color display, and scan frequency not less than 400Hz/s.Cascading port transmission signal by single line.Any two point the distance more than 5m transmission signal without any increase circuit.When the refresh rate is 30fps, cascade number are not less than1024 points.Send data at speeds of 800Kbps.
From above , we can know that their function is same , So What is difference ?
Difference is that , APA104 is more stable than ws2812b, in addtion , APA104 LED Chip is cheaper, APA104 LED CHIP is about 110usd/1000pcs , WS2812b led chip is about 120usd/1000pcs ,Then APA104 LED strip is cheaper and stable than ws2812b led strip . So I think APA104 LED streifen will replace ws2812b LED streifen soon .
