Anti-Glare Coatings with Sacrificial Surface Roughening Agents and Methods for Forming the Same

摘要

Embodiments provided herein describe optical coatings, panels having optical coatings thereon, and methods for forming optical coatings and panels. A sol-gel matrix is formed above a surface of a substrate. Organic micro-particles are embedded in a surface of the sol-gel matrix. A heat treatment is applied to the sol-gel matrix and the embedded plurality of organic micro-particles. Substantially all of the organic micro-particles are removed during the heat treatment, and after the heat treatment, the sol-gel matrix has a surface roughness suitable to provide anti-glare properties.

1. A method of forming an anti-glare coating, the method comprising:
forming a sol-gel matrix above a surface of a substrate; embedding a plurality of organic micro-particles in a surface of the sol-gel matrix, wherein the plurality of organic micro-particles have a size distribution between about 0.1 micrometers (μm) and 10 μm; applying a heat treatment to the sol-gel matrix and the embedded plurality of organic micro-particles, wherein substantially all of the embedded plurality of organic micro-particles are removed during the heat treatment, and after the heat treatment, the sol-gel matrix has an effective surface roughness between 0.2 μm and 0.8 μm.
