AI Technical Summary
In the manufacturing process of curved carrier panels, existing technologies have found that structured functional coatings are susceptible to damage from heat treatment and bending processes, leading to optical distortion and corrosion, and also incurring high costs.
A dielectric capping layer is applied to a structured region on the surface of a substrate. A transparent dielectric capping layer is formed by chemical vapor deposition methods such as FA-CVD or APCVD to protect the functional coating and reduce optical interference and distortion during heat treatment and bending.
It significantly improves the optical quality and appearance of the structured coating, prevents flow processes and corrosion, reduces costs, and improves the overall quality of the carrier panel.
