A novel package structure has been developed to fabricate quantum-dot (QD) white light-emitting diodes (WLEDs) by dispersing QDs into the backlight lens and integrating them with blue light-emitting diode to form white light. For this in-lens encapsulation structure. the luminous efficiency and lifetime of QD-WLEDs can reach 90 lm/W and 1000 h. which is 25 times longer than that of QD... https://www.chiggate.com/satisfyer-pro-penguin-next-generation-on-sale/
