Alexei Erchak
Dr. Erchak founded Luminus Devices in August of 2002 after earning a doctorate in materials science and engineering from the Massachusetts Institute of Technology (MIT). During his research, Dr. Erchak designed, fabricated and tested novel light sources using photonic lattices. In particular, Dr. Erchak pioneered the photonic lattice light emitting diode (LED) technology that underlies Luminus Devices‚ PhlatLight² technology. Dr. Erchak brings technical depth in compound semi-conductor devices, nanofabrication technology, condensed matter theory, and photonics. He has also done extensive intellectual property work.

Today's microdisplay TV (MD-TV) manufacturers are faced with the challenge of designing products that can compete with flat panel televisions; a key to sustaining market share and brand equity. To succeed, they need to continually innovate and adopt the most suitable technology; one that allows them to differentiate their products and bring MD-TVs to the next level. The fact is that arc lamps, the incumbent light source in today‚s MD-TVs, have numerous drawbacks and are a major liability to this category‚s competitive position. Manufacturers require a better light source to advance their product lines and build the next generation of MD-TVs -- ones that offer:

• Longer operating lifetime
• Faster turn on
• Wider and richer color gamut
• Lower power consumption
• No environmental hazard

This presentation highlighted the most powerful LED in the world called PhlatLight (Photonic Lattice light), developed and manufactured exclusively by Luminus Devices, whose unique properties are enabling LED-based MD-TVs for the first time. The first LED MD-TVs using PhlatLight technology appeared in stores in August and are being manufactured by Samsung Electronics. Challenges and limitations of traditional LEDs, were be explained. The presentation also described how PhlatLight technology is being extended to backlighting large-screen LCD TVs.
