dc.description.abstract在這個研究中,我們在OLED中加入準晶的結構,再將此應用於頭戴式顯示器(HMD)上面。我們使用複合式的模擬方式去計算光萃取效率和研究OLEDs在空氣中的遠場圖彼此間的關係。 模擬的結果顯示在OLEDs當中加入準晶的結構可以產生一個準直的遠場以致提昇亮度。 使用10重的準晶排列OLEDs的最大光萃取效率可以提昇至1.2倍。 相較於傳統OLEDs,OLEDs的視角可以從120度降低到26度,而頭戴式顯示器的光學效率可以改善至2.66倍。 此外在目鏡的出瞳,規一化正向的強度可以提高至3.95倍,也就是說OLEDs面板的能量可以省下74.68%的能量也可達到與傳統OLEDs一樣的正向強度。zh_TW
dc.description.abstractOrganic light emitting diodes (OLEDs) with a quasi-crystal (QC) structure are analyzed and applied in a head-mounted display (HMD) system in this study. We adopt a hybrid simulated method to evaluate the light extraction efficiency (LEE) and far-field pattern in the air, and study the relationship between them. The simulation results show that OLEDs implanted with the QC structure can provide a collimated far-field pattern to increase the brightness. Using this 10-fold QC arrangement the maxima LEE of the OLEDs can be increased by 1.20 times. Compared with conventional OLEDs, the viewing angle of the OLED panel decreases from 120 degrees to 26 degrees with an improvement in the optical efficiency of the HMD system by 2.66 times. Moreover, the normalized on-axis intensity in the pupil of the eyepiece can be enlarged up to 3.95 times which suggests that the OLED panel can save 74.68% energy while achieving the same on-axis intensity as conventional OLEDs.en_US
