Sept. 12, 2006 -- QD Vision Inc. of Watertown, Mass., announced it has been quietly developing and refining a proprietary and scalable printing technique for the manufacture of quantum dot (QD) displays and has begun discussions with commercialization partners.
The company says the fabrication method employed is derived from a quantum-dot contact printing method originally developed at MIT. According to QD Vision CEO Mark Comerford, the successful demonstration of the company's proprietary process is a technological milestone that will help pave the way for a new generation of displays that are larger, more reliable and higher quality.
The prototype red monochrome QD display has a 32 x 64 pixel count. The light emission originates from quantum dots -- tiny inorganic semiconductor nanocrystals synthesized at QD Vision. The quantum dots were printed within a sandwich of organic semiconductor thin films, which deliver energy to the quantum dots enabling light emission.
"This is the first time we have produced a multi-pixel display using our new process, which is fundamentally capable of printing the fine features required for high-resolution display applications," said Seth Coe-Sullivan, chief technology officer and co-founder of QD Vision, in a prepared statement. "In addition to making an attractive prototype display, this achievement demonstrates that QD Vision's printing method can provide the uniformity over the extremely large areas necessary for printing displays."
