SBIR-STTR Award

In this proposal, we articulate a program to develop the key technologies required to enable high resolution, full-color micro-displays. The proposed approach will exploit the development at QD Vision of high quantum yield (QY) colloidal QDs, as well as the company’s proprietary process capability for versatile manipulation of ordered 2D monolayer arrays of QDs by self-assembly and their pattern transfer and deposition on specifically targeted electrically active substrates and films. The direct deposition processes will be demonstrated for the currently used 15 microns per pixel density in the initial phase and will offer prospects for scaling down to approximately 9 microns per pixel density or higher in the future.

This Phase II proposal continues QD Vision’s research and development objectives to develop materials and processes for direct patterning of individual red, green and blue sub-pixels on silicon micro-display substrates without the use of color filters. In Phase I of the program, our efforts focused on demonstrating high resolution microcontact printing of quantum dots (QDs) and developing top-emitting QD light emitting devices (QD-LEDs). QD-LED technology has the potential to enable direct patterning of individual colors on a micro-display substrate, substantially reducing power consumption. QD-LED emitters offer narrow band spectral characteristics providing an excellent color gamut that meets or exceeds current NTSC display standards. In this Phase II solicitation, we propose a program to develop and refine the microcontact printing processes and top-emitting device structures of Phase I for fabricating high resolution, full-color QD-LED micro-displays. The proposed approach will leverage QD Vision’s development of high efficiency colloidal QDs and QD-LEDs, as well as the company’s proprietary process capability for high resolution patterned deposition of electroluminescent devices. A functional full-color QD-LED micro-display prototype will be fabricated and its performance will be characterized.
