ABSTRACT
The modern display market is dominated by the Organic Light Emitting Diodes (OLEDs). Therefore, impact of architectural and material changes on its performance is very important. The present article analyzes the Double Hole Block Layer (DHBL) architecture of OLED with respect to impact of thickness variation of the two hole block layers (HBLs) involved. Two analyses are performed. First is related to variation of thickness ratio of the two HBLs keeping their overall dimensions same. Second is related to increasing the thickness of these HBLs. The results of the analyses highlights that increasing the overall thickness of HBLs reduces the device performance. Further, changing their ratio improves the performance when ratio favours better performing HBL. However, still, changing the ratio of HBLs in device have poor performance as compared to original device. The reasons for these variations in performance are also discussed.
