What is WS2812 LED Light Strip?
WS2812 LED strip is a 3-channel addressable strip with built-in IC, controlled by dedicated LED controllers. One LED as one individually addressable pixel, IC is integrated into the LED, not visible on strips. Less components on strips, easier for installation and ben.
These LEDs are very popular among the maker community, and because of their versatility and ease-of-use, a lot of similar flavors can be found in art/lighting-related installations.The power supply of the lamp is 5V, and the single lamp addressing function can be used, that is, the RGB color of each lamp can produce a jump, and interesting functions such as running horses and running water can be made.
What is WS2812 Chip?
WS2812B is a kind of intelligent LED lamp bead which integrates RGB LED and control circuit. They are connected in series and can be controlled and communicated via a single signal line. Its appearance is the same as a 5050LED lamp bead,Each component is a pixel.The interior of the pixel contains an intelligent digital interface data latch signal shaping and amplifying driver circuit, and also contains a high-precision The internal oscillator and programmable fixed current control part effectively ensure that the color of the pixel point light is highly consistent.
The data protocol adopts the communication mode of single-line return-to-zero code. After the pixel is powered on and reset, the DIN end accepts the data transmitted from the controller and sends it first After the 24-bit data is extracted by the first pixel, it is sent to the data latch inside the pixel, and the remaining data is reshaped by the internal shaping processing circuit The DO port starts to forward the output to the next cascaded pixel. For each pixel transmitted, the signal is reduced by 24bit. Pixel point adoption Automatic shaping and forwarding technology makes the number of cascaded pixels not limited by signal transmission, only limited signal transmission speed requirements.
Up to 2KHz port scanning frequency, will not flicker under the capture of high-definition cameras,If the RESET time is above 280ÎĽs, interruption will not cause false reset.

What is WS2813 LED Light Strip?
WS2813B LED strip is a 3-channel addressable strip with built-in IC, controlled by dedicated LED controllers.The WS2813 BLED strip is similar to the earlier WS2812B LED strip that both operate at DC5v, but with the addition of a backup data line. This means that if one LED fails or is disconnected, the rest of the LEDs in the strip will still work properly.
WS2813B RGB strip lights are widely used in a variety of applications, including stage lighting, architectural lighting, and DIY projects. They are popular with hobbyists and professionals alike due to their flexibility, ease of use, and ability to create complex lighting effects.
What is 2813B Chip?
Similarly, WS2813B is also an intelligent external control LED light source integrating control circuit and light emitting circuit. Its appearance is the same as a 5050LED lamp bead,
Each component is a pixel. The interior of the pixel contains an intelligent digital interface data latch signal shaping and amplifying drive circuit, anti-reverse connection circuit, and package Contains high precision internal oscillator and high precision constant current control module
In particular, it should be noted that WS2813B realizes dual-channel signal transmission, and does not affect the overall color display in the case of damage to a single pixel.

What’s The Main Difference Between WS2812B And WS2813B?
LED pixel lighting has revolutionized the way we create dynamic, colorful, and interactive lighting displays. With a wide range of addressable LED pixel lights available, it can be challenging to figure out which one is perfect for your project. In this article, we will compare two popular models: WS2812B and WS2813B. By understanding their differences, you can make an informed decision about which one is the best fit for your needs.
WS2812B is the upgraded version of WS2812, which has integrated the drive chip and circuit into an SMD LED. WS2813B is the upgraded version of WS2812B. Like WS2812, it supports individual control and has the same 256 grays cales. The critical difference between WS2812B and WS2813B is that the WS2813 LED strip has dual data transmission, while WS2812B has single data transmission.
Below is a comparison table that shows the differences and similarities between WS2812B and WS2813 BLED strip lights.

WS2812B Application circuit diagram:
WS2813B Application circuit diagram:
WS2812B LED strips have a Positive wire, a Negative wire, and a Data wire. After upgrading, WS2813 has a positive wire, a negative wire, and two signal wires. The extra signal wire is used as a backup, which enables the WS2813 light strip can still work normally when one LED on the strip is broken. But for WS2812B, if one LED on the strip is broken, the entire strip can not work and the signal will stop at the break point. This makes the WS2813 LED strips have a more stable performance than WS2812B.
When comparing the two, it is clear that the WS2813B is dominant.
What is a break continuation?
LED Strip application breakpoint continuation refers to: when the lamp is powered on, after the output signal transmission process is interrupted by a point (that is, the IC or this group of lamp bead failure), another standby signal line can bypass the fault point and transmit the signal to the next pixel, so as not to affect the other light belt on the same line to continue to work.
Do both 2812B and 2813B have the Resumable function?
WS2812B is a single signal line, does not have the breakpoint continuation function, and WS2813B is a double signal line, so the specific breakpoint continuation function.
At present, there are two schemes for the application of breakpoint continuation in the LED Strip:
The first is a combination of series: the signal uses a double signal line cross transmission scheme; the failure can only be a single or a single group of lights that is not bright, will not cause other lights to be bright, and will not affect the overall effect of the product. For example, built-in IC: WS2813, WS2815, GS8812, external IC: TM1914, TM1934, WS2818, GS8208, etc., this type of breakpoint continuation lamp pad consists of: positive +, signal DI, backup signal BI, and negative electrode GND.
Note: If two consecutive pixel points of this type of light strip fail, the breakpoint function will fail.
The second is the DMX512 international 1990 protocol: AB double signal parallel transmission scheme, the lamp transmission signal design double line parallel transmission, the lamp line is composed of positive +, address PI, signal A, signal B and negative GND. The simultaneous failure of more than two consecutive pixels on the same line does not affect the signal transmission to the next pixel. Most outdoor lamps use DMX512 scheme lamps, which saves the trouble of maintenance, and also makes the installer no longer have to worry about the lamp strip will be broken and affect the overall effect.
Can the WS2812B and WS2813B LED strips use the same controller?
Yes, the same controller can be used for the WS2812B as well as the WS2813B. There are generally two data lines on the controller, an “A” and a “B.” When connected to the 2812B LED strip, one of the signal lines can be connected, and the 2813B LED strip needs to be fully connected to two signal lines.
Conclusion: Through the above introduction, I believe you will have a deeper understanding of 2812B led striip and 2813B led strip.In terms of performance, 2813 Bis an upgraded version of 2812B, 2813B handling and use will be better than 2812B; WS2813B LEDs are more expensive – but just slightly. A brief comparison reveals that you can purchase individual units and strips of WS2813B LEDs for around 20% more than WS2812B. The difference is not huge, so many stockists are starting to discontinue selling the WS2812B LEDs already. Although released for some time now, we expect the WS2813 to steadily gain ground and eventually replace the WS2812B.
