There are many kinds of ic built-in led ,like ws2812,ws2812b,ink1003,apa102 and so on, now it comes out sk6812 ,sk6822,sk6812 mini and ws2813 led.

Let’s talk about their difference.

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, package WS2811 into 5050LED SMD. 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.

Now a new version have come out , it is ws2813,WS2813 led have 2 data signal,any pixel’s failure won’t affect signal transfer unless two consecutive adjacent LED are Broken.

SK6812 has RGB,RGBW,WWA,SK6812 rgb is similar with ws2812b led,the main difference between the two drivers is that the SK6812 has voltage-independent color and brightness over a wide voltage range, which means that the colors of the LEDs should not be affected by a drop in the supply voltage as much as they are on the WS2812B.In addition , in our test , SK6812 LED quality is much better , when the temperature is high,ws2812b is much easy to be dead than SK6812.

SK6812 mini 3535 is mini version sk6812 led,it’s 3.5mm*3.5mm,except the size difference,others exactly the same with sk6812 led.

Sk6822 is a new technology — breakpoint transmission, this feature ensures that the rest of the LEDs in a strip still work even if one or more pixels develop a bad IC,the SK6822 LED only have IC inside the 5050, but WS2813 LED have IC and resistors, capacitors Inside the 5050 LED.That is to say, there will no need to use any resistor for WS2813 LED Strip .but for SK6822 RGB LED Strips , the resistor and capacitor are both needed.
