Is it OK to touch LCD screen?

It's generally okay to touch an LCD screen, but it's best to avoid doing so excessively or with excessive pressure. LCD screens are designed to withstand some level of contact, such as tapping or swiping during normal use, like with smartphones or tablets. However, excessive pressure or rubbing can potentially damage the screen or cause scratches, especially if you're using sharp or abrasive objects.

To maintain your LCD screen in good condition, it's a good practice to:

1. Use a soft, microfiber cloth to clean the screen.
2. Avoid using harsh chemicals or cleaners, as they can damage the screen's coating.
3. Turn off the device and unplug it before cleaning.

4. Gently wipe the screen in a circular motion to remove smudges or dirt.

Overall, just be mindful of how much pressure you're applying and what you're using to clean the screen, and you should be fine.
