Thermal Overcoat
 |
Applications |
Thermal overcoat is applied to IPS-like panel and acts a transparent planarization layer onColor resists (RGB) and Black matrix (BM), protecting color filter and providing flat surface toensure subsequent process uniformity.
|
Features |
- High transparency
- Excellent planarization ability
- Good heat and chemical resistivity
- Low UV transmittance, whichprotect RGB from UV damage
- High crosslink ratio
