Compared with LCD, OLED's characteristics is flexible, and flexibility is a key requirement for new displays such as wearable devices and VR. OLED has replaced LCD, which has become the trend of the times.
Organic luminescent materials and thin films are two key materials for OLED flexibility. Compared with ordinary plastics, polyimide has excellent heat resistance, the highest temperature resistance can reach above 400 °C, and the long-term use temperature range is -200 °C - 300 °C. The plastic substrate is used to replace the non-bending glass substrate, which is bendable but not easily deformed, and the size is very stable.
