Which coating is designed to repel oils from fingertips on touch surfaces?

• A. Anti-reflective coating
• B. Oleophobic coating
• C. Ceramic coating
• D. Magnetic coating

Answer: (B)

Oils from fingertips are lipids, so a coating that repels oils uses oleophobic properties. An oleophobic coating creates a surface with low surface energy, so oils don’t stick well. That means fingerprints are less visible and easier to wipe away, keeping the screen clear and touch-responsive. Anti-reflective coating reduces glare, not oil buildup. Ceramic coating can add hardness and some water-repellent traits but isn’t specifically designed to repel skin oils on a touch surface. Magnetic coating isn’t related to fingerprint resistance. So the coating designed to repel oils from fingertips on touch surfaces is the oleophobic one.
