Laser TV Technology: Set to Revolutionize the TV Technology
There are several display concepts that get discovered every now and then. However, many of them rarely make it past the prototype stage. Besides, those that succeed are usually too small and weak to beat the $100 billion Liquid Crystal Display (LCD) industry. However, there is a display start up by the name Prysm that is convinced that its Laser Phosphor Display (LPD) has the perfect integration of energy efficiency, picture quality and manufacturing simplicity that stand a chance to surpass the stiff competition.
The Prysm Company is based in San Jose and has caught the attention of the media especially because of the claims that the technology is more energy efficient. The Chief Technology Officer of the company claims that their technology only consumes ¼ of the power used by the LCD and also requires about 1/10 of the power used by the Plasma. The main difference between the two technologies is that LPD shines brighter.
The physics applied in saving power is simple according to the Hajjar the Chief technology officer. Other competing technologies normally require threshold power even for keeping the screen black However, lasers in LPD are allowed to rest when the screen darkens thereby saving power.
Light transmission technology in LPD is also straightforward. Beams of light composed of several UV lasers are transmitted by some movable mirrors to a screen made using plastic-glass hybrid material covered using colored phosphor stripes. The laser creates an image on the screen through scanning various lines from top to bottom. Then the energy acquired from the laser light triggers phosphor to release photons that in turn create image.
LPD has significant difference from the LCD which involves a backlight that can be made from either cold-cathode florescent of white LED light is directed to the optic layers including liquid crystals and color filters to make the image. Above 90% of energy is lost during this process. However, the conventional laser TV such as Mitsubishi LaserVue utilizes blue, green and red lasers and micromirror gadgets that combine and direct light. This technology is basically rear-projection display but its use has not been widely embraced as a result of the high price tag.
The LPD technology is almost similar to that used in the old-fashioned cathode ray tube (CRT). In the CRT, a magnet takes an electron beam to a phosphorous covered screen. But since LPD utilizes solid state lasers that are more compact and uses less power, it makes it possible for it to be made thinner and energy efficient and at the same time have same high quality of images.
The LPD technology is available especially as a result of the fast development of compact-state lighting. The fast development of LED as alternative lighting is enhancing development of LPD technology since the kind of phosphorous used in manufacturing LPD is similar to that used in coating LED light applications. The growth of LPDs is much dependent with the development of the LED lighting industry because it facilitates easy available of the raw materials. The availability of these raw materials on the shelf will save this company the hassle of having to construct semi-conductor fabrication plant like other display companies normally do. The construction of fabrication plant is normally expensive and takes a lot of time to get it running.
The reduced investment and production cost of LPD is crucial since it will allow the units to come at a lower price tag but high quality. These factors are the excellent requirements required by the best match to compete with the high muscled LCD. People are now looking for affordable high quality products and that is exactly what LPD is aiming to deliver.
