What’s The Difference? WS2812 VS WS2813
WS2812B VS WS2813
ws2813 led is ws2812 update version,dual-signal wires , signal break-point continuous transmission ,the ws2812b is regular addressable with one data wire, V+&V-.
WS2813 VS WS2812B LED Strip
The image is mainly about the difference between the work principle of WS2812 and WS2813 LED strip. The most obvious difference is: when the led one of the WS2812 was broken, it will affect the other led working, but the WS2813 will not appear above situation.
If you don’t know the WS2812 or WS2813, please allow me to introduce them to you.
Generally speaking, WS2812 has two versions: WS2812 and WS2812B. WS2812B is an upgraded version of WS2812. They are an integrating control circuit and the intelligent external control LED source of the light-emitting circuit, which looks similar to the 5050LED. It internal included intelligent digital port data latch and signal reshaping amplification drive circuit. Also include a precision internal oscillator and a 12V voltage programmable constant current control part, effectively ensuring the pixel point light color height consistent. They can be applied to the full-color module, full color soft lights a lamp strip, led decorative lighting and the indoor/outdoor led video irregular screen. The features and benefits between WS2812 and WS2812B is the WS2812B has intelligent reverse connect protection and the power supply reverse connection does not damage the IC.
Nowadays it comes to the latest version of the WS2812, which is WS2813
Compare with the former, WS2813 both have some places similar to WS2812, and have its own unique features：
Common:
1) The control circuit and the LED share the only power source.
2) Built-in electric reset circuit and brown-out reset circuit.
3) The color of the light was highly consistent, cost-efficient.
4) WS2813 LED can use same controller as WS2812B LED.
5) When the refresh rate is 30fps, cascade numbers are not less than1024 points.
6) Send data at speeds of 800Kbps and so on.
Difference:
1) WS2812 only one data signal when one led broken may affect the other led working, which only die is package in 5050 RGB LED Chip. But WS2813 led have 2 data signal, any pixel’s failure won’t affect signal transfer and its total emitting effect, unless two consecutive adjacent LED are Broken. WS2813 adopted the upgraded chips led so WS2813 led make digital led project is more reliable than before.
