Laser Phosphor Displays (LPD): higher image quality and lower power consumption

La Pantalla de Fósforo Láser (LPD) es una forma revolucionaria de crear imágenes desarrollada por la compañía estadounidense Prysm. Esta innovadora tecnología permite crear grandes pantallas con alta calidad de imagen y un 75% menos de consumo. Prysm ha plasmado su avanzada tecnología de fósforo láser en los nuevos módulos TD1 que permiten conseguir imágenes claras y brillantes en cualquier ambiente.

Laser Phosphor Display (LPD) is a revolutionary way of creating images developed by the American company Prysm. This innovative technology allows you to create large screens with high image quality and 75% less consumption.
Prysm LPD uses a laser engine that launches a beam of modulated rays onto a phosphor screen. These laser diodes use, as in optical units, small mirrors to distribute the laser beam across the entire screen. The projection surface is a layer of phosphor that is inserted into a stable structure of glass and polymers that emit red, green or light blue luminosity, responding quickly to the laser.

Unlike other technologies that lose luminosity with filters and layers, LPD uses patented laser and phosphor panel to create high resolution and bright images.

TD1, the modular solution

Prysm has put its advanced laser phosphor technology into the new TD1 modules. This TD1 modular solution is based on five key components to achieve clear, bright images in any environment. The TD1 module is the heart of the system. It consists of three parts: the phosphor panel, the laser motor, and the laser processor. It is designed to be lightweight and easy to install and configure. With a resolution of 320×240 pixels and 25” diagonal, the TD1 modules generate magnificent dynamic images, which allow us perfect vision for almost any distance and viewing angle.

The difficulty of calibrating large format displays requires hours of expensive adjustment in both system installation and maintenance. Prysm's solution to this challenge is the IP1 image processor. It supports all video signals and graphic formats, sends the content to the screen as well as offering control, monitoring and calibration. Additionally, multiple image processors can be linked together to create large screens.

As for the screen control software that this Prysm solution incorporates, it allows you to quickly create a configuration of the signal it receives, through the adjustment of parameters such as noise reduction, edge adjustment, dynamic brightness, color temperature...

An additional advantage of this Prysm proposal is that this technology reduces the heat output of the equipment so much that it does not need ventilation. Unlike other devices, the power requirement is very low, maintaining a low use temperature, which translates into great energy savings. Likewise, its robust electrical system allows you to power in a loop from the first PSU up to 4 additional PSUs (thus configuring up to 5) from the first power outlet.
From an aesthetic point of view, TD1 modules can be manufactured with a customizable frame, quickly adjusting to the chosen configuration.

Eco-efficient technology

The new eco-efficient LPD technology, behind Prysm's TD1 modules, combines low power consumption with vivid images of high quality and clarity from any viewing angle.

Its phosphor panel on which the system is based is a layered design on a rigid glass or polymer structure. When stimulated through the laser motor, the phosphor emits green, red and blue pixels, very close to the surface, without any image filters that consume electricity. Screen emission technology offers the best viewing angle (typically twice that of LCDs and plasmas), without pixel burn-in errors.

For its part, the laser engine, created from a solid-state laser diode system (similar to Blu-ray), generates a series of modulated laser beams that stimulate the phosphor panel. To completely cover the screen area with rays, they are directed through mirrors to create the number of image lines. Combining the refresh rate of 240Hz, the result offers great quality, without image flickering or motion blur effect.

The brain of the system is an intelligent technology laser processor that manages the laser motor with precision on and off as well as its intensity. Additionally, it increases system efficiency by turning off the laser when the screen is black, defining the color and positioning each pixel. Thanks to the low consumption of the laser engine, this device enables long screen life.

Finally, note that these Prysm solutions based on LPD technology are distributed in Spain by Crambo Visuales.
