What happens if you touch the LCD computer display with your hands?

Generally speaking, touch it casually, there is no problem, at most you will be exposed to a little static electricity.

It's nothing, there's a small amount of static electricity on it, and you just mess up the screen by doing that.

Pressing the LCD screen with your hands will cause damage. The nominal grade standards for mainstream LCD products are:

Class AA: An LCD display without any dead pixels is AA class.

Class A: There are less than 3 dead pixels, of which no more than one bright spot is highlighted, and the bright spot is not in the ** area of the screen.

Level B: 3 or less dead pixels, of which no more than 2 bright spots, and the bright spots are not in the ** area of the screen.

Aside from the number of dead pixels, B-grade and C-grade panels are not otherwise comparable to A-grade panels. Compared with A-grade panels, B-grade and C-grade panels have relatively uneven brightness, relatively insufficient color saturation, poor image color reproduction, and may even have damage in appearance.

In addition to using professional instruments to determine the level of LCD panels, consumers can also use the naked eye to intuitively distinguish. It is best to compare with the known A-class panels, and the B-class and C-class panels will immediately appear in their original form. In addition, panel manufacturers will also divide A-level panels into A++, A+, and A, and the best quality LCD panels are suitable for consumers with higher requirements for display quality.

Problem description: It is said that the LCD display should not be touched by hand. Is there any harm in touching it?

Analysis: There is a special coating on the surface of the LCD panel, which can prevent reflection and increase the best effect. Although the manufacturer has strengthened the panel itself and the coating, it still can't stand some people's "stinky problem" - used to touch the LCD screen with their hands, there is a certain corrosive grease on people's hands, which will slightly corrode the coating of the panel, and it will cause permanent damage to the panel for a long time.

This damaged panel will have a mottled feeling in use.

In addition, some people like to press the panel by hand, which is very interesting. It's definitely a bad habit, and it can lead to dead pixels and dark spots, which are permanent damage and can never be repaired!

If it's gentle, it's nothing. It is necessary to prevent hard bumps. LCD displays are fragile, so you should be careful not to be "bruised" by other devices when you use them.

When using detergent, you should also pay attention, do not spray the detergent directly on the screen, it may flow into the screen and cause a short circuit, the correct way is to use a soft cloth to stick the detergent and gently wipe the screen, remember, the ability of the LCD to resist "impact" is very small, many crystals and sensitive electrical components will be damaged when subjected to impact.

Also, there is one thing to note. Avoid working long hours.

The pixels of the liquid crystal display are composed of many liquid crystals, and if used continuously for a long time, the crystal will age or burn out, and once the damage occurs, it is permanent and irreparable. Generally speaking, do not leave the LCD on for a long time (more than 72 consecutive hours), turn off the monitor when not in use, or run a screen saver or let it display the screen content in full white.

LCD, quite expensive. Take good care of it. Ha ha.

Oh, that's okay, the impact resistance of the LCD is also relatively poor, because the LCD contains a lot of precision glass components and sensitive and delicate electrical components, once it is strongly impacted, it will cause damage to the LCD screen, related parts or circuits. It was okay at the time, then it wasn't too much of a problem. It's good to pay attention later.

Yes, there will be ripples on the screen when you press it, and it was fun to remember a few times, but there are fingerprints when you press it, My classmates too, press it and roar, You can rest assured, it can't be bad! If he yells, then he must be a computer novice, and he doesn't even understand this kind of common sense, you can secretly bs him in your heart! And then there's the stingy guy!

It's okay, what are you afraid of when you press it gently?

We commonly use LCD monitors.

The surface of the screen is a relatively thick layer of adhesive film,Generally, there is no problem to touch it with your hands,If there are finger prints or other dirty things on the surface,You can directly dip a paper towel in some water,Gently wipe it off。 But remember not to dip too much water into it, so that no water can flow out. If there is water flowing to the bottom of the LCD screen, it will cause damage to the LCD screen, and it is not covered by the warranty.

First of all, it is recommended to use a special liquid crystal cleaning solution, take out the special liquid crystal cleaning solution, press and hold the top 2-3 times and spray it evenly on the LCD screen. Then, remove the cleaning cloth that came with the cleaning solution you purchased and wipe it from the center of the screen outward until the adhesive sprayed on the LCD screen is clean. Then wipe the fuselage with a cleaning cloth to wipe off the dust on the fuselage.

For stubborn stains or fingerprints on the screen, you should focus on cleaning, spraying and wiping with cleaning solution and cleaning cloth repeatedly, and wipe from the center of the screen outward until the detergent on the screen is wiped clean.
