US 2025/0042801 A1 · LIGHT DIFFUSING GLASS CERAMICS

Abstract

A glass composition is provided wherein the composition exhibits wavelength independent scattering of visible light. The glass composition may comprise a spontaneously opalizing glass composition. The glass composition may comprise a fusion formable ceramic glass composition. The glass composition comprises crystals having a size greater than or equal to 1 μm. A targeted total transmittance value of the glass composition is 50% to 80%. The glass composition is configured for use as a light diffuser for a backlit display panel. The glass composition is configured such that the light diffuser appears white in transmission. A light diffuser for a backlit display panel is provided. The light diffuser may comprise a laminate comprising a core layer comprising a clear glass, and a clad layer comprising a fusion formable ceramic glass composition. The laminate may comprise a double fusion laminate.
