DC12V WS2815B Built-In IC Breakpoint Addressable Light Source SMD5050 RGB Led Pixel Chips

Features and Benefits of WS2815B Intelligent control LED integrated light source,

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

2. 12V power supply voltage can effectively reduce the working current of the whole pixel, reduce the voltage drop of the circuit board, and maximize the consistency of the mixed light when the pixel is transmitted over a long distance.

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

4. Each pixel of the three primary color can achieve 256 brightness display, completed 16777216 color full color display, and scan frequency is of 2KHz.

5. Cascading port transmission signal by single line.

6. Any two point the distance not more than 5m transmission signal without any increase circuit.

7. When the refresh rate is 30fps, cascade number are not less than 1024 pixels.

8. Send data at speeds of 800Kbps.

9. The color of the light is highly consistent, cost-effective.

Applications,

• Full-color module, LED full-color soft/hard light bar, LED guardrail tube.
• LED point light source, LED pixel screen,Special-shaped screen.

General description,

WS2815B is a intelligent control LED light source that the control circuit and RGB chip are integrated in a package

of 5050 components.It internal include intelligent digital port data latch and signal reshaping amplification drive

circuit.Also include a precision internal oscillator and a voltage programmable constant current control part, effectively

ensuring the pixel point light color height consistent.Realize two-way signal transmission, in the case of damage to a

single pixel, it does not affect the display of the overall color. 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. pixel adopt auto reshaping transmit technology, making the

pixel cascade number is not limited the signal transmission, only depend on the speed of signal transmission. Refresh Frequency updates to 4KHz, Low Frame Frequency and No Flicker appear in HD Video Camera,It is very

suitable for high-speed mobile products. RESET time>280μs , it won't cause wrong reset while interruption, it supports the lower frequency and inexpensive MCU.
