本研究可分為兩個部份，第一部分是採用熱活化延遲螢光材料(Thermally Activated Delayed Fluorescence, TADF)作為藍色發光材料，BHM9為主發光體，ν-DABNA為摻雜體製作出有機發光二極體(OLED)。以全蒸鍍方式製作於PET / ITO可撓式基板上，其發光面積為1cm x 1cm。藉由調整各層厚度，獲得PET/ITO/HATCN(10nm)/TAPC(30nm)/BHM9:10wt%v-DABNA(50nm)/TPBi(30nm)　/LiF(0.8nm)/Al(150nm)為元件最佳結構，當電壓在9V時的元件電流密度為21.75mA/cm2，亮度達到331.1 cd/m2及電流效率為1.52 cd/A，電致發光光譜波峰為456nm，半高寬為26nm。
第二部分為製作分離式紅色和綠色量子點色轉換層，藉由元件所發出的藍光穿透過紅色和綠色量子點色轉換層而形成白光，量子點溶液是利用旋轉塗佈法，調整不同的轉速參數以得到不同的厚度然後烤乾成膜。
元件藍光穿透過紅色和綠色轉換層，電致發光光譜具有三個波峰，分別是藍光456nm、綠光528nm及紅光624nm處，三色混合以得到白光，其CIE座標為(0.39,0.32)

This study can be divided into two parts, the first part : we use Thermally Activated Delayed Fluorescence (TADF) materials as blue emitting layer. A 1cm x 1cm light-emitting area flexible organic light-emitting diode is fabricated by full evaporation.
The best device structure is PET/ITO/HATCN(10nm)/TAPC(30nm)/BHM9:10wt%v-DABNA(50nm) /TPBi(30nm)/LiF(0.8nm)/Al(150nm), when the voltage is 9V, the device current dentisy is 21.75 mA/cm2, the luminence is 331.1 cd/m2, the current efficiency is 1.52 cd/A, the peak of the electroluminescence spectrum is 456nm and the full width at half maximum(FWHM) is 26nm.
The second part is to fabricate a red quantum dots (QD) color conversion layer on the back of the device. The blue light emitted by the device penetrates the red quantum dots color conversion layer to form white light. Red quantum dots use spin coating method to adjust different spin speed parameters to obtain different thicknesses and baked to form a film.
The blue light of the device penetrates the red and green QDs conversion layer, and the electroluminescence spectrum has three peaks, which are blue light at 456nm, green light at 528nm and red light at 624nm. RGB colors are mixed to obtain white light. With CIE coordinates at (0.39,0.32).
