Yasuhiko Arakawa, a specially-appointed professor, Tetsu Tatsuma, a professor at the Institute of Industrial Science, Sharp Corporation and Sharp Display Technology Corporation, have succeeded in current injection emission with a narrow emission spectrum and RGB pixel patterning with Cd-free quantum dots for the realization of next-generation high-efficiency displays. This achievement will enable the realization of new self-luminous displays that combine low environmental impact, high brightness and high contrast, and a wide color gamut. Sharp Corporation and the University of Tokyo have promoted industry-academia collaboration for more than 15 years at the University of Tokyo Sharp Lab established at NanoQuine. In particular, starting in FY2019, the research is supported by a large-scale project “Strategic Innovation Program for Energy Conservation Technologies and Development of Materials and Processes for Next-generation High-efficiency Displays” of the New Energy and Industrial Technology Development Organization (NEDO). In the near future, it is expected to be put to practical use as energy-saving devices that can be applied to small and medium displays such as head-mounted displays as well as large displays. Details of this achievement were presented at The 29th International Display Workshops (IDW’22) held in Fukuoka City from December 14.
