为什么你的手机屏幕更耐脏

Modern phone screens have an oleophobic coating that repels oils from your fingers.
This thin chemical layer reduces fingerprint smudges and makes cleaning easier with a soft cloth.
Engineers test durability by rubbing screens thousands of times under controlled humidity.
The coating wears off slowly, especially near edges where hands touch most often.
Some manufacturers now add antimicrobial agents to limit bacteria growth on surfaces.
Lab studies show coated screens host up to 80% fewer microbes than uncoated ones after one day.
Replacing the coating isn’t possible at home, but screen protectors can extend its function.
Even so, wiping gently once daily helps maintain clarity and touch sensitivity.
