OLEDs and QLEDs are rapidly emerging as the next-generation optoelectronics for flexible and wearable display applications. Most of the efficient OLEDs and QLEDs are fabricated on the ITO coated glass substrates. However, ITO substrate does not permit flexibility because it cracks easily under mechanical distress. Herein, we introduce a polyimide as flexible substrate to fabricate high-performance flexible OLEDs and QLEDs. The polyimide is chemically, and thermally stable, and exhibits high transparency, solution processability and flexibility. Instead of using ITO, we employ AgNWs network with low sheet resistance as transparent conductive electrode for the polyimide flexible substrate. Conventional-structured flexible OLEDs and QLEDs based on the colorless PI/AgNWs electrodes shows high efficiency and clear emission colors. In conclusion, this study demonstrates the potential use of PI/AgNWs structure as flexible TCE substrate of highly efficient and stable flexible OLEDs and QLEDs. |
