The market for displays, which is currently experiencing dynamic growth, uses technologies that utilizes quantum dots – currently only as converters of blue light into green and red light.
Manufacturing displays with the best technical specifications and various additional features require being able to use quantum dots as a light source.
The quantum dots used in this process must be characterized by extremely high optical properties as well as stability. They should also be produced in accordance with the EU’s RoHO (Restriction of Hazardous Substances) Directive – which means being free of toxic metals such as cadmium, lead, or mercury.
Meeting these criteria is particularly difficult in the case of quantum dots that produce blue light. Manufacturing quantum dots that emit blue light on a 450-470 mm wave link is particularly challenging not only because it requires selecting a nontoxic material with an appropriate energy gap – it is also difficult because of the various technical issues related to synthesis in the case of this kind of material.
The objective of the PureBlue projects is developing a technology that enables quantum blue-dot synthesis making it possible to use them as an active substance in LED displays emitting blue light.
During the research and development phase of this project we will be working on developing a method of quantum-dot synthesis that produces a replicable, high-quality, and stable emitter of light that meets consumer needs as well as RoHO Directive requirements.
Part of this project will also involve the construction of a prototype synthesis production line making it possible to synthesize blue quantum dots at a mass scale that responds to market needs.
