A proprietary, scalable printing technique for manufacturing displays based on quantum dots was recently demonstrated by Massachusetts Institute of Technology (MIT) spinoff, QD Vision. The company is reportedly seeking commercialization partners.

The fabrication method is derived from a quantum dot contact printing method originally developed at MIT. According to QD Vision, its proprietary process is designed to pave the way for a new generation of displays that are larger, more reliable and of higher quality than current displays.

QD Vision has developed a prototype of a 32-by-64 red pixel QD display that uses the new printing process. Quantum dots were printed within a sandwich of organic semiconductor thin films, which when driven by a current, enable quantum dots to emit light. The quantum dots are 5nm inorganic semiconductor nanocrystals synthesized by QD Vision.

Quantum dots displays are expected to provide sharper colors and cost less to make than the competing technologies like organic light-emitting diodes while using a similar manufacturing process to OLEDs.

"This achievement demonstrates that QD Vision's printing method can provide the uniformity over large areas necessary for printing displays," added Seth Coe-Sullivan, CTO and cofounder of QD Vision.

"The performance QD Vision is achieving with their current devices is a major step beyond what we previously reported in our high-efficiency QD-LEDs developed at MIT," said MIT's Vladimir Bulovic, whose research served as the basis for the company's technology platform. Bulovic serves as a member of its QD Vision's Scientific Advisory Board.

Coe-Sullivan will describe the technology at Quantum Dots 2006 in October and will exhibit the technology at the Society of Information Displays next May.
