According to Sony at 21 days through the official website released data show that the company has completed a world's initiative and Sumitomo Electric industries, successfully developed a pure green laser diode (TrueGreenSemiconductorLaserDiode ), at a wavelength of 530nm, the light output power up to 100mW or more, and the brightness of the gallium nitride (GaN ) series of green laser about 2 times, color gamut range up to NTSC182% (CIE1976 ), photoelectric conversion efficiency is more than 8%. Sumitomo Electric in 2009 began to separate R & D pure green laser diode, this is by fusing Sony to develop Blu-ray disc ( BD ) product ( use a blue laser diode ) under cultivation technology, the brightness of pure green laser diode. Sony says, in the light of the three primary colors ( red / Green / blue ), red laser diodes and blue laser diodes have been mass-produced, green laser diode using chemical materials and infrared wavelength conversion, but the light is too large and the price is the subject, and the use of GaN materials for green laser wavelength and optical output power is defined in the 520nm, dozens of mW, so don't get enough brightness. Sony said, with the pure green laser diode asked City, will let the laser source trichromatic all together, prediction can be applied to achieve with a portable laser projector laser projector with high brightness, wide color gamut or small, low power consumption and other uses. According to foreign reports, through the pure green laser diode asked City, mini projector is expected to import utility can be stored in the intelligent mobile phone ( production ). According to the report, the Sony estimates for the 2014 annual green laser diode demand will reach about 10,000,000 units, the year 2015 will be further expanded to 20,000,000, Sony and plans to a number of years the production of pure green laser diode. According to reports, the current ROHM, Nichia and American manufacturers have plans to green laser diode into mass production. OSRAM Opto Semiconductors ( OSRAM Opto Semiconductors GmbH ) was at the end of 2010, direct green emission laser ( direct green-emitting laser ) will enter mass production stage out of the laboratory in 2012. OSRAM is Matt ( 3019 ) synthesis of green laser supplier MicroVision. Reality Symposium on MicroVision Game Department of global product manager David Lashmet 2010 November in Seattle amplification (Seattle Augmented Reality Meetup) pointed out that the micro projecting products predicted 2012 will be to develop the power consumption is lower than 1W, the projection image resolution up to 1080p, the brightness of 45 lumens. | |
