2D Material-Based Flexible Displays

The integration of two-dimensional (2D) materials in the construction of flexible displays significantly enhances their transparency, productivity, and overall performance. These materials that are utilized in flexible OLED, QLED, and PeLED display technologies contribute to improved internal and external quantum efficiencies while maintaining a flexible nature, enabling superior functionality. Flexible substrates such as PET, polyimides, and flexible glass offer an optimal balance of transparency, flexibility, and thermal stability, while barrier films effectively mitigate moisture infiltration, preserving device integrity. Innovations in transparent conductive electrodes, including graphene, conducting polymers (e.g., PEDOT), and metallic nanowires, deliver enhanced durability and conductivity, surpassing the performance of traditional ITO. Additionally, thin-film encapsulation, employing layered organic and inorganic structures, ensures robust display durability, which is critical for advanced Flex-OLEDs, Flex-QLEDs, and Flex-PeLEDs.
