The working principle of flexible OLED screens is mainly based on the following key technologies:
Flexible Substrate: Flexible screens use flexible substrate materials, such as polyimide (PI) and polyester film, which have flexibility and plasticity, allowing the display to deform without damaging the circuit structure.
Thin-Film Electronics: Flexible screens use thin-film transistors, organic light-emitting diodes (OLEDs), and other thin-film electronic devices, which have good flexibility and stability, making them suitable for fabrication on flexible substrates.
Driving Circuit: The driving circuit of a flexible screen needs to be designed to be flexible or stretchable to adapt to the deformation of the display, ensuring display effect and stability.
Protective Layer: To prevent damage to the flexible screen from the external environment, a flexible protective layer is usually applied to the surface of the flexible screen to increase its wear resistance and water resistance.
Display Technology: Flexible screens mostly use display technologies such as OLED, which have advantages such as self-illumination, fast response speed, and vivid colors, making them suitable for manufacturing flexible display devices.
