Osram Turns Smartphones Into Projectors

News

Laser technology from Osram transforms smartphones into beamers

Up to now, RGB laser projections for smartphones, based on a red, green and blue laser, often had brightness problems. The reason was the often insufficient brightness of the green laser.

Green light has a special importance in RGB applications because the human eye is most sensitive in the green spectral range. The brighter the green laser shines on a surface, the brighter and stronger the projected image appears to the viewer.

Osram has now released the PLT3 520D green laser, which offers an unprecedented 140 mW at 300 mA in pulsed mode (50 percent duty cycle) for a green single-mode laser. So far, the limit for these components was 80 mW. A further advantage of the diode is its compact and space-saving TO38 metal housing with a diameter of only 3.8 mm. The laser diode with a wavelength of 520 nm has been specially developed for laser projection applications that use a MEMS scanner as the image encoder.

“Thanks to Osam's long tradition and expertise in the laser sector, we have succeeded in driving forward developments in this key technology,” explained Pedro Muñoz, marketing manager at Osram Opto Semiconductors. “Based on our quality promise, users can be confident that this technology will open up additional functions on smartphones in the medium term.”



CS International 26-27 March 2019, Sheraton Airport Hotel, Brussels

In its ninth year, CS International will continue to provide timely, comprehensive coverage of every important sector within the compound semiconductor industry. Presentations are split into 5 key themes and each industry key theme will be delivered by a keynote presentation from a leading industry figure as well as a market analyst presentation tailored to the theme. Together, the talks will detail breakthroughs in device technology; offer insights into the current status and the evolution of compound semiconductor devices; and provide details of advances in tools and processes that will help to drive up fab yields and throughputs. Attendees at the two-day conference will gain an up-to-date overview of the status of the CS industry, and have opportunities to meet many other key players within this community.
