Thermal Overcoat
Applications
Thermal overcoat is applied to IPS-like panel and acts a transparent planarization layer on Color resists (RGB) and Black matrix (BM), protecting color filter and providing flat surface to ensure subsequent process uniformity.
Features
- High transparency
- Excellent planarization ability
- Good heat and chemical resistivity
