Common Challenges and Limitations
High Modulus Transparent PI Film is an advanced film material specifically designed for foldable displays, flexible electronics, and highly durable optical applications.
It delivers high optical transmittance, excellent surface hardness, high modulus, and outstanding scratch and abrasion resistance—maintaining structural integrity and consistent visual performance even under long-term folding conditions.
The combination of high strength and high transparency makes this film an ideal key material for foldable smartphone applications.
Common Challenges and Limitations
The era of foldable displays has arrived, yet material engineering still faces critical bottlenecks:
- Insufficient surface hardness: Easily scratched; visible marks or optical degradation after ~2,500 abrasion cycles
- Limited folding durability → reduced transparency → compromised display brightness
- Insufficient mechanical strength: Accumulated bending stress leads to material fatigue
- Premium foldable devices require a complex balance of thinness, transparency, and hardness
High Modulus Transparent PI Film was developed precisely to overcome these challenges.
