Laser TV

It’s all about efficiency. Consuming about 100 watts of power, Mitsubishi’s LaserVue laser tv is a visual marvel and a class-leader in big screen energy efficiency. Mitsubishi is wise to tout the LaserVue’s low power consumption, as the FTC is currently investigating the expansion of the EnergyGuide label to cover televisions, which are one of the largest energy users within a home. All major home appliances must meet the Appliance Standards Program set by the U.S. Department of Energy (DOE). Manufacturers must use standard test procedures developed by the DOE to prove the energy use and efficiency of their products. Test results are printed on yellow EnergyGuide labels, which manufacturers are required to display on many appliances. This label estimates how much energy the appliance uses, etc.

On a separate front, Sumitomo Electric has apparently cracked the impossibility of developing a laser diode emitting in the pure-green region at 531nm. They have developed the first “true” green laser diode. Until now, creating a green beam of laser light involved doubling the frequency of an infared laser, which resulted in very poor efficiency. Many predict energy efficient blue, red and green laser diodes will revolutionize the display world, and laser tv may be the first step in this direction.
