The Next Generation of Digital Display Technology
Laser Phosphor Display (LPD) is the groundbreaking display technology invented by Prysm. It is the foundation technology for all Prysm videowall solutions which deliver breathtakingly beautiful visual experiences.
LPD technology consists of three main parts: the laser engine, the laser processor, and the phosphor panel. Fundamentally different from LED- and LCD-based technologies, LPD videowalls offer brilliant image quality, unmatched viewing angles, and the industry’s most energy efficient and eco-friendly solutions. Compared to other digital technologies, LPD technology has the lowest total cost of ownership and offers highly-competitive features, benefits and usage possibilities.
The laser processor manages the operation of the laser engine – turning it on and off, and varying the intensity the lasers' output. This sophisticated approach to light management increases the videowall's lifespan and lowers power consumption.
Built using 405nm solid-state laser diodes (similar to Blu-Ray™ technology), the laser engine generates modulated beams that address the pixels of the phosphor panel. Mirrors are used to direct the beams over the entire display area. With a scan rate of up to 360Hz, flicker-free video can be displayed with no motion blur.
The phosphor panel contains any array of red, green, blue phosphors. Each RGB triplet forms a pixel. The modulated beams from the laser engine are used to excite the phosphors and determine the color and brightness of each pixel. The phosphors are printed extremely close to the panel's surface, achieving an unmatched 178° viewing angle.
