The present invention aims to develop of novel wavelength converting films with the composited perovskite quantum dots,facilitating the application of this technology for LED backlight module.We applying PQD on chip to the components of LED backlight modules. The PQD-LEDs that are used for the backlight transmitted through a color filter exhibit the ITU-R Recommendation BT.2020 approximately 90%

本發明專利研發出環保無鎘量子點，我們稱為｢FCU-PQD｣，透過無鎘鈣鈦礦量子點製成，並採用特殊的包膜技術，透過氧化物將無隔量子點包覆在直徑30nm的殼中，此技術將量子點表面缺陷修補，提升量子點效率，且能夠達到親水與隔氧的效果，使得FCU-PQD的壽命能提高，並與現有量子點市場之產品比較，已超越含鎘之量子點效能，並已達到與含鎘之量子點的功效。

Quantum dots are used in quantum dot enhancement film (QDEF), backlight modules, Mini LEDs and Micro LEDs, as well as biomedical materials.
