Quantum Materials for Additive Manufacturing Applications

Abstract

Quantum materials’ limited emission spectrum and easily adjustable color through particle size modification make them a viable option for the next generation of displays. The emission spectrum of quantum materials is sharp and pure, which makes quantum materials ideal for display applications. As display technology advanced, self-emitting display technology eventually replaced liquid crystal display (LCD). Researchers design different types of RGB pixels in the self-emitting display area to achieve the best possible visual impact. However, different types of pixels need quantum color conversion films with various patterns. Additive manufacturing offers a novel method for quicker prototyping of red, green, and blue (RGB) pixels with a faster iteration cycle. With the additive manufacturing technique, especially the inkjet printing method, the sample is not in contact with the surfaces; only the essential components are dispensed and deposited there. The additive manufacturing technique generally reduces sample damage or containment and material waste. This chapter introduces inkjet-printing quantum materials for high-resolution display applications.
