Mitsubishi Harnesses Colored Lasers to Produce New-Generation Lightweight HDTV
`As if shopping for new flat-panel, high-definition television is not hard enough, Mitsubishi is scheduled to announce this week that it has developed commercial television that uses colored lasers to display bright, deep images on large, thin, lightweight screens — surpassing images seen on film. The television sets, which Mitsubishi is calling the first of their kind, are expected to reach stores sometime late next year.
At the heart of the first generation of this new television is an existing rear-projection technology called digital light processing. In the past, this technology, developed by Texas Instruments, used white-light mercury lamps as the television’s light source. With laser television, separate red, green and blue lasers are used in conjunction with an HDTV chip, said Frank DeMartin, vice president for marketing and product development at Mitsubishi.’
