Thermal Overcoat
 |
Applications |
Thermal overcoat is applied to IPS-like panels and acts as a transparent planarization layer on color resists (RGB) and black matrix resists (BM). It is applied onto color filter components for the protection of pixel lattice formations, while giving a planar flat surface that compensates for minor height variations in color filters. Furthermore, a thermal overcoat provides protection from chemical corrosion and higher level heat degradation. Precision, planar surfaces can then be produced that enhance coating uniformity for follow-up PS processes.
