Coatings for transparent substrates in electronic devices

An electronic device having an interior and having opposing front and rear faces, comprising:

• a housing having a rear housing wall forming the rear face, wherein the rear housing wall comprises a transparent substrate;
• and
• a coating across the transparent substrate that faces the interior, wherein the coating comprises a thin-film interference filter that exhibits color coordinate value changes Δa and Δb in Lab color space over ranges of incident light angles relative to the coating, a maximum color coordinate value change in a and b coordinates in Lab color space across all incident light angles between 0° to 60° is less than 5 in magnitude, and the coating has a reflectivity of at least 5%.

An electronic device having an interior and an exterior, the electronic device comprising:

• a glass layer having a surface that faces the interior;
• and
• a coating layer across the surface of the glass layer, wherein the coating layer includes a thin-film interference filter formed from a stack of dielectric layers, wherein the stack of dielectric layers exhibits color coordinate value changes Δa and Δb in Lab color space of reflected light over ranges of incident light angles relative to the stack of dielectric layers, a maximum color coordinate value change of the reflected light between incident light angles of 0° to 60° is less than 2 in magnitude, and the coating layer has a reflectivity of at least 5%.
