Laser Phosphor Display (LPD) technology is at the core of Prysm’s ecovative product line. This technology represents the next step in the evolution of large format displays.

What is LPD?
LPD is a revolutionary way to build high-performance, low-energy displays. Unlike traditional technology that wastes light with filters and layers, LPD uses a patented Laser Engine to convert low-power, solid-state lasers into pure light.

LPD is unique display technology combining the low-power consumption and reliability of solid-state lasers with a surface emissive screen. Fundamentally different from LED or LCD-based display technology, LPD creates a modular, highly configurable display panel with brilliant image quality and the industry’s smallest environmental footprint. To make this possible, Prysm rethought what a large-format display should be from the ground up. We wanted to build a display that had none of the competition's issues (heat output, high-energy requirements, short lifespan, etc.) while comfortably exceeding their capabilities.

What's in an LPD display?
By rethinking everything, Prysm created an advanced yet elegantly simple solution to the challenge of building a low power yet bright high-definition large format display. At the heart of the system is the TD1 tile. Each TD1 tile consists of three components: the solid state Laser Engine, the Laser Processor, and the Phosphor Screen.

The revolutionary ecovative technology behind Prysm’s TD1 display combines extremely low power consumption with vivid image quality that can be clearly viewed from almost any angle. Built around the innovative Laser Engine, the TD1 is not only the market’s longest lasting display, its lack of toxic compounds and low energy consumption sets the bar for ecovative display technology.

What kind of laser?
We use a solid state laser diode emitting a 405nm wavelength (blue-violet) laser beam. In many ways they resemble those used in high density optical storage media devices (think Blu-ray™ player). To cover the entire phosphor screen, the collection of laser beams are reflected by mirrors—the Laser Processor—to create the necessary number of image lines.
