Tokyo, Japan--Mitsubishi Electric, which is already selling a rear-projection laser TV, is now using red laser diodes in one of its edge-lit flat-screen LCD TVs to improve the color gamut. The red lasers, used along with cyan-emitting LEDs, provide the backlighting. The TV will be commercialized in fiscal 2011 and will be introduced in Japan first, according to Tech-On.
The prototype 46 in. TV has a 126% color gamut gauged by National Television Systems Committee (NTSC) standards. Mitsubishi Electric manufactures the 638-nm-emitting laser diode. It uses several tens of the red laser diode and several hundreds of the cyan LED, according to Tech-On. Specifications of the new TV are "almost the same" as those for Mitsubishi Electric's white-LED backlit TV.
