WS2813
Table of Contents
The WS2813 pixel protocol, developed by World Semi in China, is a popular choice for pixel lighting displays due to its unique features such as a redundant data line and a high PWM rate. It also comes in several variants (A, B, C, and D) with varying brightness levels to meet different budgets. The WS2813 is characterized by its compact 5050 SMD package that integrates both the control circuit and LEDs in a single unit. It is part of the WS28xx series, known for its quality and performance.
Our LED Strip Studio products support WS2813 as a pixel IC type. Let us help you with your pixel LED installation – get in touch for more information.

WS2813 Pros
- The WS2813 pixel protocol can be used with voltages up to 12V, allowing for longer cable lengths.
- It has a high PWM rate, enabling it to be filmed with cameras at a frame rate of up to 67fps.
- Its redundant data line helps reduce the risk of complete failure of the strip.
WS2813 Cons
- Its data-only feature limits refresh rates to the speed of the protocol, which may be slower than other options.
- The WS2813 has only 8 bits of data for each color, resulting in less smooth dimming curves.
