Does the E420S need to be a screen protector

It's better to stick one, it's hard to wash if it's dirty, like I pasted it is OK8's protective film, it's been used for three months, it's a little dirty on it, and I'm going to buy a new one, if I didn't paste it before, those dirty ones are on the computer, and it's even worse.

Post it, mine will be posted, it's better than nothing.

No one has said clearly which computer needs to be filmed, I personally recommend you to film it, and it is not expensive, as for the benefits, see for yourself:

The popularity of LCD screens has brought convenience to our lives, but there are also many shortcomings

1.Easy to scratch: The delicate LCD screen is very easy to scratch. Even if you carefully clean the screen with a special cleaning cloth, it is very easy to cause scratches on the screen.

2.Easy to vacuum: After the LCD screen is energized, there is a slight static electricity, which is easy to absorb dust, hair and other small impurities.

3.Easy to retain fingerprints: fingers touching the LCD screen are easy to leave fingerprints, and fingerprints are often seen in the shutdown state.

4.Difficult to clean: The LCD screen is easy to stick to saliva, saliva and oil, and it is difficult to clean. If you use chemicals such as alcohol to clean, it will have a certain corrosive effect on the screen and affect the service life of the LCD screen.

5.Low brightness: The brightness of the LCD screen is not as high as that of CRT. If the brightness is adjusted to the highest for a long time, it is easy to make the LCD tube and backlight plate age, resulting in the color cast of the LCD screen.

Using a screen protector can completely solve the above problem:

1.Prevent the aging of the screen: dust, sweat, saliva, water vapor, acid and alkali may corrode the screen, and after applying the protective film, your screen will be as good as new forever.

2.Scratch resistance: The high hardness of the screen protector makes it not easy to scratch and wear.

3.Dustproof and fingerprint-proof: The LCD screen has a slight static electricity, which is easy to absorb dust, while the screen protector is treated with anti-static electricity, which is not easy to absorb dust impurities and stick fingerprints.

4.Easy to clean: The surface of the liquid crystal film has been hardened, not only the surface dust is easy to remove, but also the liquid crystal film will not be scratched by frequent wiping.

5.Increased brightness and increased viewing angle This is because of the light-concentrating effect of the polyester film. Its principle is the same as the original mirror screen.

6.Retain your value: Because laptops are replaced faster, a clean and new screen can reduce the depreciation of your computer when you upgrade or replace it.

7.Eye protection: Computers are already something we have to face most of the time at work, so the anti-ultraviolet and anti-glare functions of the liquid crystal protective film will help reduce eye fatigue.

If there is hope.

The mobile phone is not a touch screen, it does not need an iron protective film, and it is okay to paste it if there are conditions!! The watchtower lord adopts !!

Hello! The mobile phone screen is the "window of the soul" of the mobile phone, it is recommended to paste a screen protector, and it is the responsibility of our master to protect the mobile phone!

If you don't stick the film, you basically have to change the screen after a year, and the film is less than 10 yuan for a film, and the landlord can calculate it himself.

Believe me,I'm ruined my oppo because I didn't post it.,Go to the place where you bought the phone and post it.,Although**It may be slightly more expensive than the one on the street.,But the quality is really better than the one on the street.,It's also durable.。

Sticking it can not damage the screen, it is best to go to a professional, or to an after-sales location, where it should be sold.

Just stick that ordinary one.

Don't stick the matte I used to 5800 pasted the matte sometimes to press with your fingers to press - -

Stick those with high quality for about 20 yuan.

The ones on the side of the road are easy to scratch, and they are certainly not comfortable to touch, and the film is thick, and the ones on the side of the road are mostly rough.

You can go to Jingdong Newegg and the like to buy some brand films, and then take them to the local mobile phone store and ask someone to help you apply them

Recommend benks mine has been posting this for 8 months, and there are still not many big scratches, my mother's sticker is 10 yuan, and it is full of blisters for more than 2 months.

It will be a little better to stick it down, and it is less likely to wear out.

Generally, if you get a store that sells mobile phone film, he will help you paste it, and if you paste it yourself, it is easy to paste it badly, and if you don't use it well, you still have to ask the shopkeeper to help you paste it!

If you want to post it yourself. I recommend that you first clean the screen of your phone with a little organic substance, such as alcohol. If you stick it carefully, you should be able to get it right, mainly to wash it.

The shopkeeper's sticker is his tool is good, and he often sticks it, so it's more troublesome to get it yourself, but it should be no problem!!

Peel off one end of the protective film and take off a quarter of the entire protective film, and then paste the quarter on one end of the screen, and the rest of the one that has not been removed will be slowly removed while flattening it with the other hand.

It's not easy to teach, and it takes a certain amount of time to stick it up. It's best to find someone to post **, generally around 10-20 yuan, and sometimes the bargaining price is 5 yuan. Because if you don't stick it much, you don't have experience pasting it and there are bubbles.

I've read the official review of computer newspaper laptop screen protectors on the market right now.

Although the protective film has an impact on heat dissipation, it is not large and can be ignored.

The most hurtful thing about screen protection is actually your eyes. No matter how advanced the protective film is, it will cause damage to your eyes.

My 3 notebooks have never been covered with protective films, and it doesn't matter if there is dust, just wipe the glasses cloth or lens paper.

So, for the sake of the eyes, it's better not to stick it.

In my opinion, the protective film is to protect the screen from dust, easy to clean, and to prevent it from being scratched. A layer of film does not have much effect on heat dissipation. It's like a window at home covered with plastic sheeting, and the heat will still be released.

It's not a big deal. You can use it with confidence.

It's better than nothing, if you don't often snap the lid or squeeze the LCD cover, then don't stick it.

It's best to stick one if you have the conditions.,After the notebook is used for a long time, the screen must be a lot of gray and watermarks,,, it's very dirty.,And it's not good to accidentally scratch it.,It's best to stick one.。

It doesn't matter if it's not a touch screen sticker or not, it may be poor in clarity if it's pasted.

Of course ... What does this have to do with heat dissipation...

I think it's good, it doesn't affect the heat dissipation.

It's just that the protective film is spent....

There is no flower on the phone, and it is possible to change a protective film...

It should be a protective film, and the easiest way is to remove the protective film to make sure. It's only a few dollars to change the protective film.

The phone screen is fine, or how to call it a protective film, you can change the protective film,

Tear off the protective film and take a look.

There is a high chance of scratching the screen.

It's recommended to post a better one.,It's not cool how the screen is spent, isn't it?

There are more than 100 screens, and there are up to 10 pieces of film pasted, which one is cost-effective, o(o

In most mobile phone products, a layer of mobile phone glass is used to cover the mobile phone display and touch screen, mainly to protect the display and touch screen. As a mobile phone glass, it is not an ordinary glass, considering the volume, weight, touch and light transmission and other requirements, the thickness of the mobile phone glass is generally controlled between, the surface must be very smooth and clean, the light transmission performance should be good, the whole must have a certain toughness, and there will be no cracks under pressure, and Mohs hardness (the definition of the hardness of natural minerals and common synthetic products in nature, the hardness grade of glass in the Mohs hardness is 6) should be at least 6 or above, In this way, we can ensure that the mobile phone glass has sufficient surface strength, wear-resistant and not easy to scratch.

It is recommended to apply a protective film! Sticking a protective film can prevent scratches and dust on the mobile phone screen, and at the same time, it can also protect the mobile phone and keep it beautiful! Hope you are satisfied!

Landlord: Hello.

You'd better put on a screen protector, if you don't stick it, the screen is likely to be scratched, and it won't look good (it won't affect the imaging, but the screen is not beautiful).

It's not going to be good, it's just a protective effect.

I don't need to, I think it's troublesome

In fact, it is a matter of appearance.

Yes, mobile phone repair, boutiques and 2 yuan stores are available.

Yes, it does not affect the function of the mobile phone, and it is best to pay attention to keeping the mobile phone touch screen clean, and pay attention to the mobile phone screen frequently.

Paste it well,I originally pasted the screen film and keyboard film,This screen film is my own OK8Special film,Scratch-proof、Dust-proof,It's pretty good。

This keyboard film is required to be sent by the store when you buy this book, and it is dust-proof

I feel the need! Usually dust, eating is easy to stain the screen, and even scratch the delicate LCD screen, or paste a better, the general computer city has help paste, *** point about 100 pieces!

I'll tell you my true feelings,The protection of the screen after the film is certain,At least when you scratch it, it won't scratch the screen,But the quality of the screen protector film is generally poor,Very wear-resistant,And it's hard to wipe clean after it's dirty。 Personally, I feel that if the use environment is not particularly bad, there is basically no need to paste it, but it is better to get a piece of keyboard membrane.

Whether it is a mobile phone or a computer, as long as there is a screen, there are many people who want to put film on it, do laptop screens need to be filmed?

According to the use experience, a notebook that is not a touch screen does not need to be filmed.

It's better to post it.、Actually, every time I buy my computer, it pulls up.、I don't like to block the screen.、It's uncomfortable.。

It's better to apply the film! After a long time, it is inevitable to wipe and clean! Easy to scratch the screen! It can also protect your PC.

Yes、My notebook is、Pasted at the beginning.、After two years, it's still the same as a new screen.、It's good to wipe.、It's good for the screen.、It's best to put the keyboard on the film.、You must cherish it if you have it!

I think it's better to use film, because others always like to touch your computer with their fingers, and the computer will be dirty, and if dust goes in, it will affect the sensitivity of the components inside, and it will also lead to problems such as component failure. And there will be no bad heat dissipation, after all, the computer is not dissipated through the screen to dissipate heat, if it is a professional film, it will not affect the appearance, it looks as if it is not pasted! You can use it with confidence, so many brothers and sisters have used it, no problem, what are you afraid of!

There is a special computer cleaning suit, a few dollars a set. In fact, I personally feel that it is best to buy a protective film, because it is easy to static electricity near the screen, which will absorb fine dust particles, and after a long time, due to the movement of molecules, it may enter the screen, and it is not good for **.

Actually, I don't think it's necessary as long as you don't touch it with your hands. Go buy a specially washed detergent. Anti-static, special films cost hundreds, and the dozens you paste are crooked and useless.

You can buy screen cleaning liquid, the current screen is very the outside and is not easy to scratch, and the film will cause reflection and color cast problems, affecting eyesight.

Is it necessary to stick? Can it be protected? It is said that the heat dissipation is not good! I think the layer of plastic and screen protector that comes with my book doesn't have much impact on heat dissipation,Because the heat of the screen is not large。 You can consider.

Depending on what functional protective film you buy, some can protect eyesight, reduce eye fatigue, electrostatic protection, dustproof, and anti-scratch. If you don't post it, it's okay to clean it up often.

There's no need to put on the film, it's the same as dust, buy a set of special cleaning laptop screens, there is a special screen cleaning water and cloth, there is too much dust, just wipe it.

You can buy a notebook cleaning kit for cleaning.

If you're afraid of getting dirty, buy a laptop screen film and stick it.

As long as it is a notebook that has been turned on, then there is more or less dust on the screen, and the film is only anti-scratch and it is impossible to prevent dust, and the notebook does not need to be filmed at all, because the notebook display is not like the mobile phone display, and the mobile phone display is sometimes put together with hard objects, but the notebook is closed when it is not used.

Because the display screen is energized, there is static electricity to absorb dust, and the display screen film is not conducive to heat dissipation.

The above is just a personal opinion.

It can be cleaned with a computer cleaning kit. It's best to put a protective film on.,It's good for protecting the computer screen.。。

The notebook that has been used for four years has not been pasted with any film, and it is still the same as new. This is still a personal favorite, and the screen film has a lot of effects, such as reducing radiation and dustproof. The bad part may be that the heat dissipation is slow.

It's good to use it with care. In the case of keyboard film, it means that I have been buying a new keyboard and it is easy to use. Personally, I think it's too ugly to put a film on the laptop keyboard.

The advantage is to prevent occasional sprinkling, some people have been tricked. Actually, when I designed the notebook, I took into account everything you thought, so I didn't add any film, and it was always good. Just take care of it.

There's no need, mine is not pasted, it's good to wipe it usually, and there is dust when you paste it.

There is no need to post it.

Take a soft cloth and wipe it with some water.

It is necessary. Not for the protection of the screen, but also for the convenience of cleaning in the future. Paste the film, and if the screen is dirty, you can directly wipe it with a damp cloth, and you can't do it without the film.
