Unique Opportunities Can SSL Transfer Optical Data to Mobile Devices?
Short Term Prioritized Gaps & Recommendations < 3 years Prioritized Gap SSI enabling technologies, manufacturing infrastructure and supply chains are emerging but relatively undeveloped. Electronic components and devices rather than optical ones gate LED and OLED product performance and product lifetime. SSI specific software and modeling tools to optimize assembly of LED and OLED SSI devices are limited. Recommendations Significant cross industry education is required to create a robust ecosystem. Develop SSI specific SMT technologies for fabricating LED light engines and light sources. As OLED technology progresses, develop SMT and R2R tools for flex or rigid substrate systems. Education of electronics design industry to SSI market opportunities and product requirements to develop extensive supply chain. Develop SSI specific software for designing and fabricating LED an OLED light engines and light sources within environmental and thermal constraints.
Long Term Prioritized Gaps & Recommendations > 3 years Prioritized Gap SSI cost/lumen has not shown the same improvement rate as luminous efficacy. Roll-to-Roll processing for manufacturing companies is not a high yielding core competence for OLED manufacturing. SSI Product lifetime does not meet advertised targets. SSI standards are trailing industry development pace. Recommendations Develop LED and OLED materials to produce high-efficiency light sources. Develop configurable and standardized in-line measurement and inspection tools for R2R processes. Develop Accelerated Life Tests (ALT) appropriate for long life-time designs, with ALT results validated with real time performance data. Prioritize failure mechanisms (e.g., optical, electronic, mechanical, component, etc.) so industry can address relevant issues Maintain consistency and streamline standards development. Develop standards to insure that public policy conforms to technical capability.

BASF & Philips 1st to develop OLED for use as transparent car roof The OLEDs are transparent when switched off, allowing for a clear view outside the vehicle, yet providing light only within the vehicle when switched on In addition to offering completely new design possibilities, the transparent OLED lighting concept also allows new approaches to automotive engineering. The transparent OLED sandwich structure can be combined with equally transparent solar cells. http://www.printedelectronicsworld.com/articl es/basf-and-philips-1st-to-develop-oled-foruse-as-transparent-car-roof-00004230.asp "This combination allows the driver to enjoy a unique open-space feeling while it generates electricity during the day and pleasantly suffuses the interior with the warm light of the transparent, highly efficient OLEDs at night," said Dr. Felix Görth, head of Organic Light-Emitting Diodes and Organic Photovoltaics at BASF Future Business GmbH.
Audi to introduce OLED lights to future vehicles The company expects to be using OLED rear lights relatively soon whilst they see brake lights a few more years away. But Berlitz visualizes white OLEDs being used for daytime running lights and side lights. The biggest target of all - especially for Audi's designers - are three-dimensional OLEDs. The first prototypes are now appearing as part of a project with public support, installed on various levels in the rear light units of an Audi TT. http://www.printedelectronicsworld.com/articles/aud i-to-introduce-oled-lights-to-future-vehicles- 00004327.asp
