Power-Line Carrier · Pixel Driver ICs
Every bead carries its own address — app control, music sync, motion capture, game integration. Light dances to any signal you send.
Why Power-Line Carrier
Shift registers need three wires; DMX512 needs five. Faced with a legacy string that gives each bead just two legs, modulating the signal onto the power line is the only way through. It's the path PowerMOS has bet on for two decades.
Three-wire architectures like the WS2811 are fast, backed by a mature ecosystem, and have long dominated signage and LED strips. But the signal passes bead to bead, so a single failure breaks the whole string — a hard ceiling for premium outdoor work.
Born from stage lighting, this industry standard gives every bead its own address, and a single failure stays local. The trade-offs are a 250 Kbps ceiling and a high per-node cost — refresh rates struggle once bead counts climb.
Modulate the address and grayscale data onto the power line and each bead needs only two legs. Individual addressing, failures that stay local, and support for automated in-line addressing — the line PowerMOS has kept refining ever since.
From Wafer to Bead
The address code is the soul of a pixel bead. PowerMOS pairs laser-trimmed metal fuses with in-line-writable poly fuses to build a proprietary two-layer address architecture — beads can be assembled from randomly picked reels, then written one by one on the line with an address that matches their exact position.
Product Families
From premium full-pixel control to cost-optimized fixed code, from low-voltage DC copper-wire lights to high-voltage AC installations — spec it all in one place.
Third-generation anti-interference architecture with falling-edge decoding and noise filtering. A single channel drives 256+ beads, at both high and low voltage.
An independent white channel delivers both true color rendering and pure white — built for premium retail and professional installations.
Two-layer addressing lets a single feed reel handle both assembly and addressing. Fits automated lines and supports 2D curtains and 3D sculptural forms.
Patented two-section address design; laser-trim grading of synchronized, random and sectioned functions delivers unbeatable value for high-volume full-color tree lights.
Why PowerMOS
The only supplier that develops the entire chain in-house — chip architecture, protocol, addressing process and control system — with a ~200 PPM defect rate and 100M+ chips shipped.
Our own camera-addressing patents plus eight formal licenses cover controller methods, address burning and bead structure. Choosing PowerMOS means choosing full IP protection too.
