The technology is advancing by leaps and bounds, that’s impepinable, and the world of image, of course, not free.
One company that is developing new technologies on large screens is prysm, a U.S. company which stands by laser phosphor screens (LPD), and the technology to implement in the near future as they have the perfect combination of image quality, energy saving and low cost, its battlefield weapons to compete with existing liquid crystal displays (LCD).
According to Roger Hajjar, CTO of the company, an LPD display consumes a quarter of the energy that an LCD with the same brightness, and about a tenth of the energy of a plasma display.
On the other displays the light source is on most of the time and requires a certain amount of energy even to maintain the black screen. With the LPDS, lasers stop working when the screen is black, resulting in energy savings.
The mechanism underlying a laser display works as follows: a beam of light from various ultraviolet lasers are directed by a group of movable mirrors on a screen made of a hybrid material between glass and plastic color phosphor strips. The laser draws an image on the screen by scanning each of the lines from top to bottom. The energy of laser light activates the phosphor, which emits photons and produces an image.
According to the company, this type of laser phosphor screens soon be used in large screens, billboards in cities, etc.. and could also soon replace the LED screens.
