This pixel protocol was designed by World Semi in China. WS2811 V1.4 is the newly revised version of WS2811, featuring a higher PWM rate and different data timing. It offers many of the benefits the WS28xx series is famous for, making it one of the most common protocols for pixel lighting displays. The control circuit comes in a SOP8 package, allowing for more flexibility with LED choice.

WS2811 V1.4 Advantages
- Up to 12V, allowing for long cable lengths
- High PWM rate allows for filming these pixels with cameras up to 67fps
WS2811 V1.4 Disadvantages
- Data-only restricts refresh rates to be limited by the speed of the protocol, which will generally be slow
- Only 8 bits of data for each color makes dimming curves less smooth
- No redundancy in data
