Bright low-power displays using Digital Micro Shutter(tm) technology.

Dr. Lodewyk Steyn
Pixtronix Inc.

Mobile multimedia devices such as smart phones, portable media players and navigation (GPS) devices are playing ever increasing roles in our daily lives.  Consumers are no longer just talking and texting, but finding their way, catching the news and watching the latest movies and videos.  As we use these devices for more applications and for longer amounts of time, we need larger, brighter, better image quality displays that don’t drain the battery dry.  Today’s LCD technologies struggle to support these requirements. The Pixtronix display technology makes a fundamental breakthrough in the power / performance trade off, delivering 145% NTSC color gamut (CIE 1976), 24-bit color, 1,000:1 contrast ratio and 170° view angles, all at roughly ¼ the power consumption of competing TFT-LCDs. At the heart of this technology is a MEMS-based Digital Micro Shutter™ (DMS™) device that enables the low power, high speed light modulation in the Pixtronix displays. This talk will highlight some of the design innovations in the Pixtronix DMS technology, along with the manufacturing principles that have guided the design process.

Lodewyk Steyn is the Lead MEMS Engineer at Pixtronix Inc. and is responsible for the design and characterization of the proprietary Digital Micro Shutter™ (DMS™) technology of Pixtronix. He was involved with the company since its inception in 2005 and assisted in the due diligence process that resulted in an initial financing round of $9 million. Born in South Africa, he obtained his B.Eng. degree in mechanical engineering from the University of Pretoria. He then relocated to Cambridge, MA to obtain his S.M. and Ph.D. in MEMS at the Massachusetts Institute of Technology. Dr. Steyn likes working with all aspects related to MEMS development, including the design, fabrication and reliability of MEMS devices, as well as the supporting engineering systems and processes required to transform MEMS from a benchtop technology into a product. When he’s not designing MEMS devices he can be found mountain biking, snowboarding or kite surfing.
