Abstract
A color conversion film with green and red color conversion materials is needed for mini-LED based LCD displays because the traditional approach of using phosphors on-chip does not work for such displays due to technical limitations. Either narrow band phosphors (like B-Sialon or KSF) or quantum dots (like CdSe or InP) are commercially used in color conversion films and the selection of these materials is mainly driven by display performance including picture quality but also battery-life. We present and discuss the pros and cons of the different material combinations in relation to the specific display types of TV, monitors, notebooks and tablets and will show where perovskite quantum dots will make a difference. Furthermore we give an update on the development and commercialization status for our color conversion films which are based on green perovskite QDs and different red emitter materials.
