WS2813 and SK6822 LED

August 31, 2017/in Blog /by admin

First ,WS2813 and SK6822 dual signal , both of the signal is data , why 2 data signal?, it is for led strip one led is broken , another data still can work ,unless 2 next led Two successive LED is broken then the led strip can not working .

which can make the led strip one is broken will not affect another led working ,but the frequency speed WS2813 is much better than WS2812B . it is much better than ws2812b and sk6812, and when WS2813 VS WS2812B ,you can think WS2813 LED is ws2812b updated version , and SK6822 is sk6812 updated version , but we can see the difference from the led strip picture between the WS2813 AND and sk6822, You can see the SK6822 LED strip have led chip and capacitors in the led strip , but WS2813 LED strip only have led chip on the surface of led strip , this is Becasue WS2813 led chip not only have the ic ,but also capacitors package in 5050.

by the way ,When i compare the datasheets WS2813 and SK6822 , The SK6822 specs mention ESD pressure (ElectroStatic Discharge), but WS2813 does not., so i can not make sure WS2813 have it or not. but WS2813 is really very good as the Capacitors is packaged in 5050, and have much faster frequency speed than WS2812B.

Many of my customer complaint about the led is easy to be broken sometimes . as they have not bake them before they use those led chip , those led chip MLS lever is 6, which mean they need to bake before you welding them . you need to bake them 24 hours on 60-70 degree enviroment ,after you bake , you need to use them in 24hours , and

the welding temperature is better not more than 240degree, on 230-235degree is ok .

Whats The Difference? Ws2813A Vs Ws2813B（Ws2813）

June 26, 2017/in Blog /by admin

First let me introduce the ws2813 addressable led chip:

1, General Description:

WS2813 is an intelligent control LED light source that the control circuit and RGB chip are integrated in a package of 5050 components. Its internal include 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, which achieves highly consistent color effect.

The data transfer protocol use single NZR communication mode. After the pixel power-on reset, the DIN port receive data from controller, the first pixel collect initial 24bit data then sent to the internal data latch, the other data which reshaping by the internal signal reshaping amplification circuit sent to the next cascade pixel through the DO port. After transmission for each pixel, the signal to reduce 24bit. Every pixel adopts auto-reshaping transmit technology, making the pixel cascade numbers are not limited to the signal transmission, only relate to the speed of signal transmission.

The BIN receives the data signal, and then compare the data with the DIN side after phagocytosis of 24bit data, if DIN do NOT receive the signal, then switching to BIN for receiving the input signal, which ensure that any the IC’s damage does not affect the signal cascade transmission and make the BIN in state of receiving signal until restart after power-off.

Refresh Frequency updates to 2KHz, Low Frame Frequency and no Flicker appear in HD Video Camera.

250us or more of reset time, it won’t cause wrong reset while interruption, it supports the lower frequency and inexpensive MCU.

There’re in a choice of 18mA or 5mA current version, and also in a choice of high brightness or cost-effective version. That is to say, WS2813 is provided with four versions.

2, Fetures :

1, The control circuit and the LED share the only power source.

2, The control circuit and RGB chip are integrated in a 5050 components, to form an external control pixel.

3, Using the built-in signal reshaping circuit to achieve the signal waveform shaping, and no distortion of waveform of signal takes place.

4, Built-in power-on reset and brown-out reset circuits.

5, The gray levels of each pixel are of 256 levels, which achieves “256*256*256=16777216” full-color display, and the refresh frequency reaches to 2KHz/s.

6, Serial cascade interface, data receiving and decoding depend on just one signal line.

7, Dual-signal wires version, signal break-point continuous transmission.

8, Any two point the distance more than 3m transmission signal without any increase circuit.

9, When the refresh rate is 30fps, cascade numbers are far more than 1024 points.

10, Data transmitting at speeds of up to 800Kbps.

11, Good color consistency reliability, high cost-effective.

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.
