摘要
Background: Organic Light Emitting Diodes have emerged as a potential candidate for being used as the display because of their remarkable performance. In the past decade, a lot of interest was shown in their development and improvement. Scientists utilized different methods for enhancing their performance which included the change in OLEDs architecture. Different supporting layers (charge injection, transportation and blocking) are added in the architecture to enhance the performance of OLED. Some of the patents related to the application of the OLED have also been reviewed to observe the utilization of the present work in those applications. Objective: The motive of this research article is to analyze impacts the impact of different layers on the performance of OLED. Methods: The objective is achieved by systematically analyzing the impact of different layers on the OLED. The analysis commenced by investigating the properties of the basic OLED consisting of the emission layer only. Thereafter, in succession different supporting layers are added to the OLED architecture. Subsequently, after adding each layer, OLED device is analyzed and its properties are determined. Finally, the performance of different layers is compared. Results: The outcome of the above research study shows that these supporting layers are significantly able to enhance the performance of the OLED. Step by step layers are added to the architecture and enhancement in the performance is observed. There is an improvement of 13% to 38% not over the basic OLED architecture, but over the multilayered OLED device, which is already far better than the basic OLED. Conclusion: Therefore, from the analyses, it can be concluded that the different layers are significant for the OLED architecture and improve the performance of the OLED considerably.
