High efficient OLED displays prepared with the air-gapped bridges on quantum dot patterns for optical recycling
An optically efficient structure was proposed and fabricated to realize high brightness organic light emitting diode (OLED) displays based on a white OLED prepared with the air-gapped bridges on the quantum dot (QD) patterns. Compared with a conventional white OLED display, in our experiments, the optical intensity of the proposed OLED display shows the enhancement of 58.2% in the red color and 16.8% in the green color after applying the air-gapped bridge structure on QD patterns of 20 wt% concentration. This enhancement comes from the two facts that the QD patterns downconvert unnecessary blue or blue/green light to the required green or red light and the air-gapped bridges increase the color conversion efficiency of QDs by optical recycling using total internal reflection (TIR) at the interface. In addition, the color gamut of the proposed OLED display increases from 65.5 to 75.9% (NTSC x, y ratio) due to the narrow emission spectra of QDs.

Quantum Materials Corp Achieves Record Performance for Pure Red Cadmium-Free Quantum Dots
“ Our primary focus is on driving cadmium-free quantum dots as a phosphor replacement in OLED displays , in concordance with Apple’s recent announcement regarding their integration of quantum dot and OLED technologies into QD-LED for future iPhone displays. Our materials are the foundation for accelerating development of QD-LED displays and making them a reality for mobile devices. QD-LED display form factors are more desirable for mobile devices and quantum dots as a phosphor replacement will radically improve color performance and energy efficiency over current OLED technology ,” said Toshi Ando, Quantum Materials Corp VP of marketing.
Our process is quickly scalable to industrial-volume production at a price point commercially viable for next-gen QD-LED display development efforts such as Apple’s,” We have already made a great deal of progress working with our film partners to integrate our materials into optical film for LED display applications and it was a natural progression for us to leverage that experience into QD-LED photo resist film applications concluded Quantum Materials’ President and CEO Stephen Squires.
