Introduction

WS2812 is an intelligent control LED light source with its control circuit and RGB chip integrated into a 5050 package. It incorporates an intelligent digital port data latch, a signal reshaping amplification drive circuit, a precision internal oscillator, and a 12V programmable constant-current control section, effectively ensuring highly consistent pixel color output. The data transmission protocol uses a single-wire NZR communication mode. After power-on reset, the DIN port receives data from the controller. The first pixel captures the initial 24 bits of data and latches them into its internal data register; the remaining data is reshaped by the internal signal reshaping amplification circuit and forwarded via the DO port to the next cascaded pixel. Each pixel transmission reduces the signal by 24 bits. Pixels employ automatic reshaping and forwarding technology, so the number of cascaded pixels is not limited by signal transmission constraints — only by signal transmission speed. The LEDs offer advantages including low drive voltage, eco-friendliness, energy efficiency, high brightness, wide scattering angle, good consistency, low power consumption, and long lifespan. The control chip is integrated directly onto the LED, resulting in a simpler circuit, smaller footprint, and easier installation.

Features

• Control circuit and RGB chip integrated within 5050 package, forming a complete pixel control unit.
• Built-in signal reshaping circuit; reshaped signal forwarded to the next-stage driver, preventing waveform distortion accumulation.
• Built-in power-on reset and power-off reset circuits.
• Each pixel's three primary colors support 256 brightness levels, enabling 16,777,216-color full-color display at a scan frequency of no less than 400Hz/s.
• Cascaded ports transmit signals via single-wire transmission.
• Signal transmission between any two points exceeding 5 meters requires no additional circuitry.
• At a refresh rate of 30fps, cascade count is no less than 512 pixels in low-speed mode and no less than 1024 pixels in high-speed mode.
• Data transmission speed up to 800Kbps.
• Highly consistent luminous color with excellent cost performance.
