Opto-ceramic converters receive innovation award

Brighter than the sun: Opto-ceramic converters from SCHOTT are accelerating the adoption of laser phosphor-based digital projectors by enabling high luminance light sources. The technology group now honored the material and the respective development team from Mainz (Germany) and Penang (Malaysia) with the SCHOTT Innovation Award 2018.
By 2020, one-third of all projectors will use laser diodes or LEDs. This so-called solid state lighting (SSL) enables higher brightness, a superior image quality, and very good reliability in digital projectors. Thus, the technology has the ability to take high quality, cost-effective digital projection to the classroom, the boardroom, the home theater, and the cinema.

After years of research, SCHOTT experts have developed two inorganic ceramic phosphor materials that are extremely temperature-stable, heat-conductive, and energy-efficient. The phosphor materials are green and yellow fluorescent ceramics that convert blue laser light into yellow light. The yellow light is segmented by color filters to generate the primary colors (red, green, and blue) for digital projectors.

“The new ceramic phosphor converters, which were awarded with the SCHOTT Innovation Award 2018, provide superior performance with an outstanding reliability that enables long-lasting laser light sources. This means that there is no need to change lamp bulbs, which significantly lowers the total cost of ownership and energy costs”, explained Dr. Frank Heinricht, Chairman of the Management Board. 

SCHOTT pre-produces the ceramic phosphor converter material in Mainz (Germany) and finishes the material at its Penang plant in Malaysia. This value chain connects the outstanding production excellence of “German Engineering” with highly competent processing expertise, and short distances to markets like Japan, China, and Taiwan where the newest digital projectors are developed and produced.

“SCHOTT is one of the technology leaders in this field and has already started to serve the top producers of professional-grade digital projectors used in movie theaters and at major events,” said Philippe Younès, Director of Business Development at SCHOTT Advanced Optics. “With the market launch of two solutions that are available in mass production, we want to grow our global sales and enter new markets and applications quickly. We want to brighten up the world with our technology.”
