Mitsubishi's new TV is the first to use laser light, which produces exceptionally vivid color.
Like some existing TVs, Mitsubishi's uses an array of tiny, movable mirrors; red, blue, and green light beams strike the mirrors and are reflected onto the screen in different combinations.
But because laser light is so pure--all its photons have exactly the same wavelength--the color combinations can be much more precise. The TV will be on the market by the end of the year.
Mitsubishi announced last week that it is restructuring the company through a plan that will see a reduced workforce, and a refocus to the production and sales of large-screen visual displays in both its commercial and consumer business units.
The home model of its laser-powered Laservue (less than 73 inches) will be discontinued, but the company is determined to concentrate on micro display rear and front-projection systems measuring 73 inches and larger.
In other news, sources are reporting the Australian based Arasor International is close to folding. This claim comes nearly three years after the company allegedly reported false statements about key laser tv patents it held and its alliance with Mitsubishi’s marketing of the Laservue.
Mitsubishi Electric Corporation has released the ML520G54, a high output power laser diode, offering 110mW CW radiation at 638nm in stable lateral single-mode. The diode is ideal for use in mobile projectors, laser show equipment, and instrumentation applications, as well as in the biomedical fields.
"We took costs into consideration for commercialization," it said. "And we found that the red color laser is more effective than the other lasers." The laser is manufactured by Mitsubishi Electric. Its emission wavelength is 638nm.
Lasers are extremely bright and can obviously be harmful to your eyes, but there will be several layers of safety. Among the options are filters and interlocks, making it virtually impossible for one to be exposed to the harmful laser components. Because laser light is so perfectly focused, there is the illusion of speckling when a laser is viewed on a surface. However, this will easily be remedied by a de-speckling modulator or passing the light through some other filter, breaking up the light before its viewed on the screen.
