The Next Generation of Digital Display Technology
Laser Phosphor Display, or LPD, is the groundbreaking display technology and large format display platform invented by Prysm. It is the core of all Prysm Digital Display Solutions, and to many, it represents the next generation of large format digital displays. LPD consists of 3 main parts: the Laser Engine, the Laser Processor, and the Phosphor Panel (described below).
LPD uses a patented laser engine and a phosphor panel to create stunning, lifesize images with low-power, solid-state lasers. Fundamentally different than LED- and LCD-based technologies, LPD solutions—packaged configurations containing LPD technology and other components—are designed to a human scale and offer brilliant image quality, unmatched viewing angles, and the industry’s smallest environmental footprint. Compared to other digital technologies, Prysm’s LPD technology has the lowest total cost of ownership and offers highly-competitive features, benefits and usage possibilities.
How It Works
LPD technology powers Prysm’s patented tile. Each tile includes three components: a Phosphor Panel, a Laser Engine, and a Laser Processor. Prysm uses a solid-state laser diode emitting a 405nm wavelength laser beam.
Laser Processor
The Laser Processor is the smart technology that manages the Laser Engine—turning it on and off, and varying its intensity. Along with the technology’s inherent low power consumption, this sophisticated approach to light management increases the display’s lifespan and lowers power consumption.
Laser Engine
Built using solid-state laser diodes (like Blu-Ray™,) the Laser Engine generates modulated beams that energize the Phosphor Panel. To completely cover the display area, the beams are directed by mirrors. Combined with a fast refresh rate of 240 Hz, this results in flicker-free video with no motion blur.
Phosphor Panel
The Phosphor Panel has a pattern of phosphors layered in a rigid glass or polymer structure. When excited by the Laser Engine, the Panel emits red, green or blue light forming image pixels. Since the phosphor is printed extremely close to its surface, the display is able to achieve the highest possible viewing angle of any display technology on the market.
