51‐2: Optical Efficiency Improvement of QD‐OLED Technology with Structural Design and Material Selection

The low light extraction efficiency of QD‐OLED restrict its wide application in high‐resolution full‐color display. Optical structural design optimization of the relative width and distance of quantum dot & blue‐OLED cells, the introduction of the refractive‐matching material and selective optical films are utilized to solve this problem. On the whole, a >40% efficiency improvement and >90% coverage of BT. 2020 color gamut have been achieved.
