研究目的
To develop TASF materials technology for deep blue OLEDs with high efficiency and low efficiency roll-off, addressing the bottleneck problem of low efficiency in blue devices.
研究成果
The research achieved deep blue light display meeting the standard requirements of NTSC with high efficiency and effectively suppressed the problem of efficiency rolling. The efficiency BI index still reached more than 300 under the application requirement of brightness, marking a critical step closer to the actual application of high-efficiency blue OLED.
研究不足
The molecular polarity of the sensitizer affects the electroluminescence spectra to some extent, and the microcavity effect also affects the color purity. The functional layer materials show a great influence on the device performance.
