LIQUID LENSES AND LIQUID LENS ARTICLES WITH LOW REFLECTIVITY ELECTRODE STRUCTURES

Abstract:

A liquid lens article that includes: a first substrate; and an electrode disposed on a primary surface of the first substrate. The electrode comprises an electrically conductive structure disposed on the primary surface of the first substrate and an optical absorber structure disposed on the electrically conductive structure. The electrode comprises a reflectivity minimum of about 3% or less at a visible wavelength within a range of 390 mm to 700 nm, and a reflectivity of about 25% or less at an ultraviolet wavelength within a range of 100 nm to 400 nm. Further, the absorber structure comprises an absorber layer comprising a metal oxynitride and the electrically conductive structure comprises a metal layer comprising a metal that differs from the metal of the absorber layer of the absorber structure. In addition, the electrode can comprise a sheet resistance from about 5 .OMEGA./sq to about 0.5 .OMEGA./sq.
