Technical Name Novel composited perovskite QDs for white LEDs application on backlight module
Project Operator Feng Chia University
Project Host 賴俊峰
Summary
The invention developed the novel wavelength converting films with the composited perovskite quantum dots (FCU-PQDs), facilitating the application of this technology for LED backlight module. The FCU-PQDs LEDs that are used for the backlight transmitted through a color filter exhibit the ITU-R Recommendation BT.2020 approximately 90% (a National Television System Committee value of 120%).
Scientific Breakthrough
This pattern aims to develop of novel wavelength converting films with the composite perovskite quantum dots (FCU-PQDs). We develop an innovative technology, applying FCU-PQDs on chip to the components of LED backlight modules. FCU-PQDs on chip have enhanced the light efficiency over 30% (approximately 80 lm/W). The ITU-R Rec. BT.2020 value of FCU-PQDs on chip could over 90% using for backlight module of LCD.
Industrial Applicability
This technology developed the FCU-PQDs on chip of white light source, which can be directly applied to develop QD-LCD.  FCU-PQDs will also use for mini-LEDs and micro-LEDs. For FCU-PQDs are expected economic benefits. Large-size TV displays are expected to increase to 86% by 2020. The TV market expects QD-LCD shipments to increase from 5 million units in 2017 to 50 million units in 2020, with values estimated revenue of $10.6 billion.
