Method of treating a glass surface and treated glass articles

A method of making a backlight unit, comprising:

• directly coating a first major surface of a glass substrate with at least one of 3-mercaptopropyl trimethoxysilane, aminopropyl triethoxysilane, or silanated PMMA;
• depositing a plurality of PMMA-containing light extraction dots on the coated first major surface.

A display backlight unit, comprising:

• a glass substrate comprising a first major surface and a second major surface opposite the first major surface, the first major surface coated with at least one of 3-mercaptopropyl trimethoxysilane, aminopropyl triethoxysilane, or silanated PMMA, and a plurality of light extraction dots comprising PMMA deposited on the coated first major surface,
• wherein after exposure at 60° C. and 90% relative humidity for 240 hours, a color shift dy exhibited by the glass substrate is less than about 0.007 per 300 mm path length through the glass substrate and luminance changes by less than 10%.
