Pixel Protocol Overview: WS2812

This pixel protocol was designed by World Semi in China. WS2812 offers many of the benefits the WS28xx series is famous for, as well as being the first in the series to offer an integrated LED design. Typically, users will choose WS2813 or above for higher quality, however WS2812 is still one of the most common protocols for pixel lighting displays. The control circuit and LEDs are integrated in a 5050 SMD package, which provides a small physical footprint for each pixel.

WS2812 Advantages

WS2812 Disadvantages

  • Data-only restricts refresh rates to be limited by the speed of the protocol, which will generally be slow
  • Low PWM rate makes theses pixels unsuitable for cameras
  • Only 8 bits of data for each color makes dimming curves less smooth
  • No redundancy in data
