Antireflective and Easy-to-Clean Technology
Product InformationBenefits • Eliminates approximately 90% of
reflections from external light sources• Improves the display
contrast and color gamut by reducing reflections from the top of
the surface • Aids in the removal of oil, dirt, and other smudges
as a result of the hydrophobic and oleophobic properties of the
surface
treatment• Improves the tactile qualities of the touch screen as
a result of the low-friction surface treatment • Enables excellent
process and color control • Optimized for a variety of unique
customer specifications, including subtle color shifts in the
reflectance spectrum
Application• Tablets and convertible notebooks• Computer
monitors• Point-of-sale kiosks• Optical components• Laptops

Corning’s Antireflective and Easy-to-Clean Technology mitigates
approximately 90% of ambient reflections from a single air-glass
interface.

Corning’s Antireflective and Easy-to-Clean Technology readily
increases the *contrast ratio of common displays in ambient outdoor
lighting conditions (e.g., partially sunny day or overcast
day).

Antireflective and Easy-to-Clean Technology Enhances Contrast
Ratio and Color Gamut of Displays in Outdoor Ambient Conditions
* Display Luminance ~ 500 cd/m2 ,Ambient Conditions: 5000 cd/m2,
Surface reflections: 0.5 – 4%, Internal reflections: 2, 4, or
8%
The CIE color gamut of Corning® Gorilla® Glass with
Antireflective and Easy-to-Clean Technology is approx 3X greater
than untreated displays in ambient sunlight. In outdoor lighting
conditions (e.g., partially sunny day or overcast day) ambient
reflections at the various layers below the cover glass can grossly
reduce the color gamut of a display. An ideal display module with
Corning’s Antireflective and Easy-to-Clean Technology can restore
much of the display’s color gamut in bright outdoor conditions.

30% of color gamut, premium display w/ AR/ETC (Rtot=2.5%)

Chemically-resistant, Wear-resistant and Environmentally Robust
Hydrophobic CoatingAfter extreme exposure to sweat, salt mist, high
temperatures, and humidity cycles, Corning’s Antireflective and
Easy-to-Clean Technology demonstrates high optical transmission,
low haze, and high hydrophobicity.
After 95 hours of continuous wiping (~520k wipes) with a denim
cloth under a 1kg load, Corning’s Antireflective and Easy-to-Clean
Technology maintains high hydrophobicity and optical clarity.
Assuming the average user wipes their device 20 times per day,
these results suggest the coating could survive 71 years of daily
wiping.
