Touching with what, and how hard?<\/p>\n\n\n\n

Even on screens that aren’t meant to be touched (e.g. not a touchscreen!) a simple tap or swipe with a fingertip, where the screen is not visibly deformed, won’t do any harm except maybe to leave behind a little skin oil. <\/p>\n\n\n\n

A harder touch may cause the LCDs to visibly react with swirls and whorls, but if you don’t press too hard, no permanent damage accrues.<\/p>\n\n\n\n

But — of course! — if you press any screen with a sharp object, you may damage its covering; and if you press very hard even with your finger you may damage the internal components of the screen.<\/p>\n\n\n\n

BTW: Most screens sold as “LEDs” are still actually LCDs, but with an LED backlight. Only “emissive” technologies, such as xOLED, are true LEDs with no backlight.<\/p>\n\n\n\n

But in any case, they’re all fine with common-sense handling: The no-sharp-object, gentle-touch rule is pretty universal.<\/p>\n\n\n\n
