Liquid crystal displays (LCD) are used in a wide variety of applications, ranging from smartphones and tablets to automotive dashboards, machinery control panels and computer monitors. The technology is characterized by the use of liquid crystals which are illuminated to produce an image. There are several benefits associated with LCD, including efficient use of energy, minimal heat production, and greater longevity. But like all display devices, even LCDs must be cleaned on a regular basis to function as intended.
Do Turn Off the Device
It’s always a good idea to turn the LCD device off before attempting to clean it. When the device is on, it will produce a small but noticeable electrostatic field, which could result in a shock when exposed to moisture. Whether it’s a TV, tablet, etc., turn the device off before cleaning.
Do Use a Mixture or Rubbing Alcohol and Water
There are numerous cleaning products on the market designed specifically for LCD displays. However, one of the safest and most effective solutions is to use diluted rubbing alcohol. Take an empty water bottle and fill it with 1 part water and 1 part isopropyl alcohol. Shake the bottle until the solution is thoroughly mixed, at which point you can use it to clean your LCD device.
Don’t Use Paper Towels
While it may seem harmless enough, using paper towels to clean an LCD isn’t recommended, as it will leave behind small fibers on the display that could impact its accuracy and functionality.
Do Clean with a Lint-Free Microfiber Cloth
Instead of using paper towels to clean your LCD device, it’s recommended that you use a lint-free microfiber cloth.
Don’t Spray with Glass Cleaner
Why shouldn’t you spray an LCD device with glass cleaner? The problem with glass cleaning products is that most of them contain harsh chemicals like ammonia, acetone, toluene or methyl chloride. Depending on the exact cocktail of chemicals found in the cleaner, it may cause the LCD display to turn yellow and/or weaken, making it susceptible to cracking and other forms of damage. Just to be on the safe side, it’s recommended that you avoid all types of traditional glass cleaning sprays and products when cleaning your LCD device.
