研究目的
To improve the optical efficiency in QD-OLED display by using white OLED as the excitation source instead of blue OLED.
研究成果
The novel QD-WOLED structure using white OLED as the excitation source significantly improves the optical efficiency, achieving more than 3 times higher optical intensity compared to QD-BOLED. This enhancement is attributed to the yellow portion of white light that passes through the CF unabsorbed by the QD film.
研究不足
The study focuses on the optical efficiency improvement but does not extensively discuss the lifetime and stability issues of the proposed QD-WOLED structure.
