how do i clean tv lcd screen made in china

If your screen is still dirty, apply a small amount of 70~75% isopropyl alcohol (IPA) solution to your cloth and gently wipe down the exterior of your screen. Alternatively, you can also use a 70~75% IPA wipe.

As the weather warms, it"s time for everyone"s "favorite" pastime: spring cleaning. While you"re dusting off the shelves and shoveling out a winter"s worth of detritus, spare a moment to check your TV. Dust and grime can accumulate there, and over time it can become more and more noticeable. And if you have children, there may be an array of fingerprints and other smears on the screen.

The short version? Don"t use liquids, don"t press too hard, don"t use any traditional cleaners. Microfiber cloths are good, but be gentle. Modern TVs are predominantly plastic and therefore far easier to scratch than windows or your phone.

Want the longer version? Here"s what the top TV manufacturers say about cleaning their screens:Cleaning your 4K, OLED, or LED TV screen with a soft, dry cloth is recommended. The goal here is to avoid scratching the screen. Gentle, circular motions tend to give better results, since the circular motion hits each area from several angles in a single swipe.

Caution: Don"t spray water or other liquids directly on the TV, as electric shock could occur.Turn the TV off and let it cool down for a few minutes before unplugging it.

To clean the frame and screen, gently wipe it with a microfiber cleaning cloth. Make sure to wipe the TV frame and screen as gently as possible. TV screens are fragile and can be damaged when pressed too hard.

Important: Never use any type of window cleaner, soap, scouring powder, wax, or any cleanser with solvents such as alcohol, benzene, ammonia, or acetone. Never use abrasive pads or paper towels. If you do, you can scratch the screen or strip the anti-glare coating off the screen and cause permanent damage. Never spray water directly onto the TV. Make sure to wipe the TV as gently as possible. TV screens are fragile and can be damaged when pressed too hard.Gently wipe the screen or the exterior with a dry, soft cloth, such as an eyeglass cleaner.

For inks from oil markers on the screen, soak a cloth in a non-soap synthetic cleanser diluted (by less than 1% ) with water. Squeeze the cloth tightly to eliminate excess liquid, then wipe gently to remove the ink. Use non-soap cleansers cautiously because it may cause environmental problems when disposed improperly.

So why not Windex? Regular Windex is formulated for glass windows, plus a few other surfaces. It contains ammonia and alcohol, not the friendliest of chemicals. S. C. Johnson doesn"t explicitly say not to use Windex on TVs, but it offers Windex Electronics wipes and cleaners, so infer what you will. The better screen cleaners will clearly state that they do not contain alcohol or ammonia.

At last count, I found a billion companies making TV screen cleaners. Almost all of these are something like 99 percent water, 1 percent other stuff. Years ago I tested a handful and found them, on average, to work well enough. If you don"t have luck with a simple cloth and possibly distilled water, a screen cleaner is worth a try, and as a bonus you can also use it for your laptop, tablet and cell phone screens. Plus, they come with a microfiber cloth. If they don"t clearly state they don"t contain alcohol and ammonia, however, I would skip them.

So yeah, cleaning your TV is a good idea. But just remember that they"re exceptionally fragile. Why risk marring their surface by using cleaning methods the companies themselves don"t advise? If you damage your screen with cleaners, you won"t be able to fix it.

My advice? Get a nice microfiber cloth (if your TV didn"t come with one), and use that. If that doesn"t fix your smudges, try a cloth moist with water. Don"t press too hard. There"s less than a millimeter between your finger and a broken TV.

Screen cleaning kits are fine, though most people won"t need them. Remember, like all TV accessories, the store is selling them because they probably make more profit on that $20 kit than on a $500 TV.

Television screens are supposed to be clean and free of dirt, dust, or any debris that may blur vision. This is why this component is one of the most vital parts of a Television. Nothing can be worse than straining your eyes to make sense of the pictures your set is projecting. If you do not clean your TV regularly, fingerprint smudges and dust will build up.

Cleaning your LED TV or any type of television for that matter is something you should do at least once every 2 or 3 weeks. In fact, I will suggest that you do it as often as you watch it any paying more attention to the screen when you do so. If you clean your TV set regularly, it will always look brand new, and you will enjoy bright and colorful pictures without said. Bearing that in mind, there are ways to go about a cleaning endeavor. Unfortunately, not everyone knows how to clean a set effectively. Many think that a piece of towel soaked in water will do. How wrong they are. Television screens are very sensitive, so a great deal of care is required to do the job effectively. In addition to that, being careful also protects the screen for damage. Secondly, you need to understand that TV sets are different. Although they all project sounds and images, they are built differently. So, therefore, the approach to cleaning should also be different as well.

The approach to cleaning an LED TV screen, for instance, requires extra care compared to the cleaning of a Tube TV. They both have screens, but the former is more sensitive than the latter due to the sensitivity of LED screens build material. Bearing all this in mind, how do you safely clean an LED TV screen without damaging it in the process. In this article, we will show you safe and intelligent ways to go about it using available and affordable materials. You will also learn a few tips about how to do it safely too.

Before you proceed, you need to bear two things in mind when cleaning LED TV screens. Firstly, you want to do it in such a way and with the right materials that ensure the screen is clean and devoid of dust or stains of any kind. You want your screen to be as bright and clear as possible. Secondly, you want to avoid damaging the screen or reducing its projection quality. This is why it is necessary to use only the right cleaning materials and approach at all times. Now, here are some helpful tips for adopting when cleaning an LED television screen. [/fusion_text]

Every electronic equipment comes with an owner’s manual. This manual provides the user with sufficient information about how to use and maintain the gadget. The same thing goes for LED sets. They come with an owner’s manual too. Before you clean the set, you may want to read the manual first.

In fact, it is advisable that you read it first immediately you buy and install it in your home. By reading the manual, you gain more understanding regarding how to care for the television all through it a lifespan in your home, office, or wherever you install it. For the purpose of cleaning, pay attention to the section that provides information about how to do it effectively.

Reading manuals is important because different television manufacturers provide different approaches to cleaning their sets. What works for an LG LED TV may not work for a Samsung set. That is why it is so important to only follow the recommendation of a one cap fits all approach to cleaning your TV screen. If you read the manual when you bought it, but you have forgotten the cleaning details, consult it once again to refresh your memory.

Before you start the cleaning properly, turn off the television set. Do not stop at that. You also need to unplug it from the power source. Once you have done that, do not start cleaning the screen immediately. Give it time to cool down. The cleaning process may take between 2-5 minutes or even more depend on your LED TV model or how long it was on.

Turning the TV off will cut off power leading to the cooling down of the screen. You don’t want to be cleaning a hot or warm screen, do you? You want to make sure that the screen is as cool as possible and non-reactive to whichever cleaning agent you use.

Another advice to take in that is so important is that you should never use paper towels to clean the screen. There are reasons to avoid paper towels. Paper towels, especially when soaked in water, leave smudges and stains on the screen. No matter how long or how hard you try to wipe the marks off, they yet remain. Paper towels are bad for your TV screen. It’s as simple as that.

To enjoy an ultimate cleaning experience, you should consider using microfiber cleaning pieces. Some people recommend cotton whole because they are more breathable. However, microfiber cloths are more durable. In addition, they do not stick to your screen. Older LED, or LCD screens can’t handle traditional cleaning methods or materials. With microfiber, you can eliminate stains, remove smudges, and fingerprints with ease.

To use microfiber, simply wipe the surface of the screen in a circular motion. Cover as much part of the screen as you possibly can. Work your way around the edges as well. More importantly, when cleaning, avoid touching the screen with your bare hands as doing so will leave fingerprint marks on it.

The use of chemicals should be avoided at all costs. Chemicals damage screens more than you know. That a chemical agent worked on a particular surface is not an indication that it will work well for your TV screen. LED screens are very sensitive and fragile, so you ought to make sure that you keep chemicals as far away as possible. Another material you should never use is a detergent solution (water and detergent).

Soap, scouring powder, was window cleaners, and any other general industrial cleaner should be avoided. Abrasive pads and towels made from paper should not be used either. Using any of these materials will lead to screen scratches, anti-glare coating damage, or permanent screen damage. The sad part is that the damage may not be noticeable at first, but over time, the same will become permanent.

If you must wet your cleaning material with water, do so in little splashes. Avoid spraying the screen directly with water. When wiping the screen, do so gently because it can break if pressed too hard as screens are very fragile.

You will notice that your microfiber cloth cannot reach the edges of the screen like the other areas. If you don’t clean the edges too, dust and first will accumulate in those parts, and after a time removing the stains will love difficult. Furthermore, failure to clean screen edges will lead to an uneven appearance, with poor picture quality being the end result. To clean edges and corners effectively, use cotton swabs to greater effect. For better results, dab the cotton swabs in water. Pick off the dirt carefully by dragging them out using the swabs. Do this for the four corners of the screen.

As for the edges, run the swabs up and down systematically but avoid running them all the way down to the edges as this may drive dirt further on that may be difficult to remove. For better results, use as many cotton swabs as you can.

Unlike an LED TV screen, cleaning a Tube TV is much easier. Tube TV screens are more rugged and can withstand pressure, but doing so carefully is also important. You can use a microfiber cleaning cloth doused in a little water. Never spray the screen directly as this may damage it. Rather, work your way with the microfiber cloth. Apply the same circular cleaning motion like you would do an LED TV screen. Cotton swabs will also come in handy to pick off the dirt from the screen corners.

Dish soap can also be used on LED and LCD screens, albeit with care. Before you use a dish soap solution, first wipe the screen with a dry cloth to remove dust. Now, dip your cleaning cloth in the dish soap solution. Squeeze off the liquid then gently wipe the screen. Make sure you cover every surface area. Once you are done, don’t waste time to clean; otherwise, the solution will dry up on the screen leading to a blurry vision. Rinse the cloth with water to remove soapy residue then take the dry cloth you used to wipe off the dust once again to dry the screen.

Yes, they do. There are actually cleaners specially made for cleaning tv screens. Screen cleaners contain distilled water, isopropyl, and alcohol solutions. If you must use an electronic screen cleaner, make sure you shake to content before use. Also, apply on a limited portion of your cleaning cloth.

Cleaning your TV remote control is part of a general TV cleaning process. So to clean your remote control, follow these tips. Pop-out the batteries:Remove the batteries from the remote. Doing so will create enough room when cleaning the interior casing.

Tap the remote lightly on a hard surface:Remote controls gather a lot of dust and debris along the way. To remove them, tap the remote control on a hard surface like a table. Do this gently and several times to dislodge debris stuck in crevices.

Use a mild disinfectant:Apply a cleaning disinfectant on a piece of cloth and clean the body thoroughly. The use of disinfectant is necessary because our hands carry germs, and we transfer these germs to the remote control anytime we operate it. Clean the whole body thoroughly.

Maintain a weekly timetable:To ensure that your TV set is always clean, make sure you clean it weekly. Add it as part of your to-do list when cleaning your home. If your furniture deserves regular cleaning, so does your television set. Doing regular cleaning will atop dust, debris and fingerprints from smearing the screen. It is also much easier to clean when there is little dust on the surface. Keeping a microfiber cloth close by is also advised so that you can quickly wipe off dust when necessary.

Never spray your LED TVset directly with any substance:Avoid spraying your screen directly with any substance even if it is an electronic cleaning gel. Excessive spraying can damage the cabinet and the structural make-up of the screen. If you must use any cleaning solution, apply it on the napkin or microfiber cloth you are using and gently wipe the screen with it.

Use a Vacuum:To draw out dust and debris hidden in the crevices of the set, use a low suction vacuum. You may also use the vacuum cleaner’s soft brush to remove dust from the cable, vents, and ports of the TV

Adhere strictly to the User Manual:Your LED TV set comes with a user manual for a reason. The manual is meant to guide your use of the device. When cleaning your set, make sure you follow the directives of the manufacturer. Doing it any other way may damage the TV beyond repair.

Avoid strong cleaning agents:Just like we pointed out in the article, avoid strong cleaning agent as not all of them are good for your television’s screen. The screen is very sensitive, so bear this in mind. Some examples of cleaning agents to avoid include unmixed alcohol, ammonia, acetone, and Wax.

Maintaining your LED TV set requires a lot of patience and attention to detail. If you want the screen to remain in good shape, you need to clean it regularly and with proper cleaning materials. If you follow the tips in this article, your screen will remain bright and sharp for as long as you use the set.

Now that the NFL football season has kicked off, you probably want to see all the on-field action as clearly as you can. But TVs, like other electronic items, can attract dust and get marred by blemishes, such as children’s fingerprints.

While you’re at it, also pay attention to the remote controlsfor your TVs, cable boxes, and streaming players. These get handled much more than TVs and harbor pathogens along with plain old grime. We have advice for cleaning both TVs and remotes below.

When it comes to TVs, the current market is dominated by superbright, big-screen LCD (LED) and OLED TVs. However, many of us still have older sets, including plasma TVs, which companies stopped manufacturing in 2014, and even CRTVs—also called tube TVs—which started disappearing around 2008.

If you’re cleaning an older tube TV, you have a bit more flexibility because its screen is made of glass and can be cleaned like other glass items in your household. In this—and only this—instance, it’s okay to use a window cleaner, such as Windex.

More modern TVs are far more sensitive and need to be cleaned carefully to keep the screens from getting scratched or damaged. Plasma TVs also have glass screens, but manufacturers often applied a sensitive anti-glare coating, so they should be treated like an LCD or OLED TV rather than a CRTV set.

In all cases, turn off the TV—or even unplug it—prior to cleaning, says Claudio Ciacci, who heads Consumer Reports’ TV testing program. “In addition to it being safer for the set, it’s usually easier to see dirt or finger smudges when the screen is dark,” he says. “It also gives the TV a chance to cool down.”

If you have any doubts about which type of TV you have, you can always consult the owner’s manual. Most manuals and manufacturer websites have instructions for the best way to clean their sets.

Screens can scratch easily, and even paper towels and tissues contain fibers that can do damage. “Your best bet is to use a soft, anti-static microfiber cloth—the kind used to clean eyeglasses and camera lenses—and wipe in a circular motion,” says John Walsh, who cleans more than 250 TVs a year in his role as a CR photographer. (Some TV manufacturers will include a cloth for this purpose.) “Gently wipe the screen with a dry cloth to remove dust and other debris, but don’t press too hard,” he says.

You may also want to wipe down the TV’s cabinet, and make sure dust isn’t clogging the vents that help dissipate heat. If the TV is on a stand and not tethered to the wall, Walsh suggests cleaning with one hand while supporting the TV with the other to prevent the set from tipping over. However, CR strongly recommends anchoring all stand-mounted TVs using anti-tipping straps designed for this purpose.

If there are hard-to-remove stains, you can dampen the cloth slightly with distilled water and gently clean the screen. Don’t spray water directly onto the screen; that could cause a shock or component failure if water seeps into the inner workings of the set.

For the most stubborn stains, you can try using a solution of very mild dish soap highly diluted with water, once again applied to the cloth and not to the TV itself. (As a guideline, Panasonic used to recommend a 100:1 ratio of water to soap.) LCD screens, in particular, are very sensitive to pressure and can scratch easily, so don’t press hard.

Alcohol and ammonia, found in window cleaners such as Windex, can wreak havoc on your expensive flat-screen TV, so don’t use cleaners that have them. If you decide to use a packaged “screen cleaner”—which you don’t really need (see below)—choose one that doesn’t contain alcohol, ammonia, or acetone. Also, don’t use any cleaners that contain an abrasive that can scratch the screen.

Some of these kits cost $15 to $20 for just a microfiber cloth and a small bottle of cleaning solution, which is probably mostly water. Instead, buy the cloth at an office supply store or online and use distilled water, or a solution of your own making per our advice above. If you opt for a kit, make sure it doesn’t contain harmful chemicals.

Remote controls can get dusty and also harbor a fair number of germs. Think of how many fingers have pressed the buttons on that remote recently and whether all of them were squeaky clean. Then there’s the issue of coughs and sneezes.

Here’s some basic advice about cleaning your remote controls. We also have more details on how to sanitize your remote control if you’re really worried about spreading viruses.

Remove the batteries before you start cleaning. Then start by turning the remote upside down so that the buttons are facing downward, and tap the remote against your palm to dislodge any debris that might have fallen between the buttons. Wipe down the entire remote with a soft cloth that has been sprayed with a tiny bit of alcohol diluted with water. The cloth should be damp, not wet.

To clean in and around the buttons, you can use a cotton swab dampened with the alcohol/water mix. More stubborn debris lodged deeper into the keys can be dislodged with a dry toothbrush or wooden toothpick.

While we’re on the subject of TVs, if you’re thinking of shopping for a new set, you can check CR’s TV ratings, which are available to members. We buy every set we rate at retail, just like a consumer would, then evaluate it using a rigorous testing protocol. Here are three 65-inch sets that combine big screens and strong performance, and all at a price of about $1,000.

One of today’s modern technological wonders is the flat-panel liquid crystal display (LCD) screen, which is the key component we find inside televisions, computer monitors, smartphones, and an ever-proliferating range of gadgets that display information electronically.What most people don’t realize is how complex and sophisticated the manufacturing process is. The entire world’s supply is made within two time zones in East Asia. Unless, of course, the factory proposed by Foxconn for Wisconsin actually gets built.

Last week I had the opportunity to tour BOE Technology Group’s Gen 10.5 factory in Hefei, the capital of China’s Anhui Province.This was the third factory, or “fab” that Beijing-based BOE built in Hefei alone, and in terms of capability, it is now the most advanced in the world.BOE has a total of 12 fabs in Beijing, Chongqing, and several other major cities across China; this particular factory was named Fab 9.

Liquid crystal display (LCD) screens are manufactured by assembling a sandwich of two thin sheets of glass.On one of the sheets are transistor “cells” formed by first depositing a layer of indium tin oxide (ITO), an unusual metal alloy that you can actually see through.That’s how you can get electrical signals to the middle of a screen.Then you deposit a layer of silicon, followed by a process that builds millions of precisely shaped transistor parts.This patterning step is repeated to build up tiny little cells, one for each dot (known as a pixel) on the screen.Each step has to be precisely aligned to the previous one within a few microns.Remember, the average human hair is 40 microns in diameter.

On the other sheet of glass, you make an array of millions of red, green, and blue dots in a black matrix, called a color filter array (CFA).This is how you produce the colors when you shine light through it.Then you drop tiny amounts of liquid crystal material into the cells on the first sheet and glue the two sheets together.You have to align the two sheets so the colored dots sit right on top of the cells, and you can’t be off by more than a few microns in each direction anywhere on the sheet.The sandwich is next covered with special sheets of polarizing film, and the sheets are cut into individual “panels” – a term that is used to describe the subassembly that actually goes into a TV.

For the sake of efficiency, you would like to make as many panels on a sheet as possible, within the practical limitations of how big a sheet you can handle at a time.The first modern LCD Fabs built in the early 1990s made sheets the size of a single notebook computer screen, and the size grew over time. A Gen 5 sheet, from around 2003, is 1100 x 1300 mm, while a Gen 10.5 sheet is 2940 x 3370 mm (9.6 x 11 ft).The sheets of glass are only 0.5 - 0.7 mm thick or sometimes even thinner, so as you can imagine they are extremely fragile and can really only be handled by robots.The Hefei Gen 10.5 fab is designed to produce the panels for either eight 65 inch or six 75 inch TVs on a single mother glass.If you wanted to make 110 inch TVs, you could make two of them at a time.

The fab is enormous, 1.3 km from one end to the other, divided into three large buildings connected by bridges.LCD fabs are multi-story affairs.The main equipment floor is sandwiched between a ground floor that is filled with chemical pipelines, power distribution, and air handling equipment, and a third floor that also has a lot of air handling and other mechanical equipment.The main equipment floor has to provide a very stable environment with no vibrations, so an LCD fab typically uses far more structural steel in its construction than a typical skyscraper.I visited a Gen 5 fab in Taiwan in 2003, and the plant manager there told me they used three times as much structural steel as Taipei 101, which was the world’s tallest building from 2004- 2010.Since the equipment floor is usually one or two stories up, there are large loading docks on the outside of the building.When they bring the manufacturing equipment in, they load it onto a platform and hoist it with a crane on the outside of the building.That’s one way to recognize an LCD fab from the outside – loading docks on high floors that just open to the outdoors.

LCD fabs have to maintain strict standards of cleanliness inside.Any dust particles in the air could cause defects in the finished displays – tiny dark spots or uneven intensities on your screen.That means the air is passed through elaborate filtration systems and pushed downwards from the ceiling constantly.Workers have to wear special clean room protective clothing and scrub before entering to minimize dust particles or other contamination.People are the largest source of particles, from shedding dead skin cells, dust from cosmetic powders, or smoke particles exhaled from the lungs of workers who smoke.Clean rooms are rated by the number of particles per cubic meter of air.A class 100 cleanroom has less than 100 particles less than 0.3 microns in diameter per cubic meter of air, Class 10 has less than 10 particles, and so on. Fab 9 has hundeds of thousands of square meters of Class 100 cleanroom, and many critical areas like photolithography are Class 10.In comparison, the air in Harvard Square in Cambridge, MA is roughly Class 8,000,000, and probably gets substantially worse when an MBTA bus passes through.

Since most display manufacturing has to be done in a cleanroom and handling the glass requires such precision, the factory is heavily automated.As you watch the glass come in, it is placed into giant cassettes by robot handlers, and the cassettes are moved around throughout the factory.At each step, robots lift a piece of glass out of the cassette, and position it for the processing machines.Some of the machines, like the ones that deposit silicon or ITO, orient the glass vertically, and put them inside an enormous vacuum chamber where all the air is first pumped out before they can go to work.And then they somehow manage to deposit micrometer thin layers that are extremely uniform.It is a miracle that any of this stuff actually works.

It obviously costs a lot to equip and run such a fab.Including all of the specialized production tools, press reports say BOE spent RMB 46 billion (US$6.95 billion). Even though you don’t see a lot of people on the floor, it takes thousands of engineers to keep the place running.

The Hefei Gen 10.5 is one of the most sophisticated manufacturing plants in the world.On opening day for the fab, BOE shipped panels to Sony, Samsung Electronics, LG Electronics, Vizio, and Haier.So if you have a new 65 or 75-inch TV, there is some chance the LCD panel came from here.

When it comes to cleaning, flat-screen TVs and LCD screens require special care and a gentle touch. With the wrong technique, you can easily scratch the screen or damage the surface"s antiglare coating. Even rubbing too hard can cause pixels (the tiny dots that compose images on computer monitors and TV screens) to burn out and stop working permanently. Most household cleaning products are too harsh to use on electronic devices with LCD or OLED screens, so choose your TV cleaning strategy carefully. These tips on how to clean a TV screen will help protect your device while ridding it of dust, smudges, fingerprints, and streaks.

To avoid damage to your TV while cleaning, only use gentle products. Never wipe the screen with paper towels, abrasive sponges, or coarsely woven rags, which can cause scratches. Instead, use high-quality, finely woven microfiber cloths to clean TV screens, recommends cleaning expert Leslie Reichert.

You should also avoid cleaning products that contain alcohol or ammonia. These types of cleaners can remove antiglare coatings and cause images to become cloudy or distorted. A simple swipe with a microfiber cloth ($9 for 5, Amazon) is typically all that"s needed to remove dust and other debris from the screen"s surface. When more than a light dusting is required, however, use the guidelines below for the best way to clean a TV.

Practice preventative measures so you won"t have to clean TV screens often. Keep food, drinks, and kids away from TV and computer screens to eradicate risks of messy splatters and fingerprint smudges. During your weekly house cleaning, lightly dust the screens with a microfiber cloth to prevent dust buildup.

Whether you’re gaming or burning the midnight oil on a work project, there’s nothing more annoying than a dirty computer screen. The only problem is that most computer screens are highly sensitive and require a delicate touch to prevent damage.

If you’ve ruined a monitor before or you want to keep that brand new laptop running smoothly, this article will provide you with all the information you could possibly need to keep your screen squeaky clean without damaging it.

Wondering how to clean your laptop screen without causing any damage? You don’t have to be a tech guru to understand that any kind of liquid getting into the hardware of your laptop spells disaster. Because of this, you should avoid liquid sprays.

One of the most common mistakes people make when attempting to clean their laptop computer screens is using a liquid cleaner. As a general rule, try to avoid them altogether, however, there are few safe liquid substances you can carefully use to clean laptop screens.

If you aren’t having much luck with a dry cloth or if you spilled something on your screen, you can try using a bit of rubbing alcohol (for non-LCD screens) if you don’t want to buy a specified cleaning product.

The trick, of course, is to not let any of the liquid get down to the speakers or keyboard and to use an extremely small amount - just enough to remove the dirty spot.

If you have an LCD screen, do not use rubbing alcohol as it will damage your screen. If you’re unsure about what products are safe for your laptop or you aren’t completely sure what kind of screen you have, look up the products that the manufacturer lists as restricted for cleaning.

With the right cloth or material, a cleaning substance may be completely unnecessary. Microfiber cloths are the best possible material to clean your PC with, since paper towels, household rags, and old T-shirts will scratch and damage your screen.

Of course, there will be instances where no amount of gentle wiping will remove the soda your toddler spilled on your laptop a week ago. In these circumstances, you may have to turn to a serious computer cleaning solution or rubbing alcohol. Just remember that when you clean your laptop’s screen, a delicate touch is vital to the long-term health of your display.

Sometimes you can’t splurge on ultra-expensive products when trying to clean your laptop screen and you have to rely on alternative methods. There are plenty of household items that can be used, such as rubbing alcohol. However, there are some that are dangerous to your screen which you should try to avoid.

A brand new sponge is a great way to clean a screen. You will need to lightly dampen the sponge (but not too much); the last thing you want is for water to drip down into your laptop.

If, and only if, you have a glass laptop screen, it’s safe to use Windex as a cleaner. Sturdier computers sometimes have a clear glass screen over the front of the display - much like a cell phone. A bit of Windex sprayed onto your microfiber cloth will certainly get the job done. But remember, never spray the Windex directly onto your laptop screen itself.

If you don’t have a microfiber cloth or a sponge fresh out of the package, a soft duster brush will work. A traditional feather duster might damage your screen but there’s a good chance you’ve adopted the Swiffer® duster into your household. These cleaning cloths are made from thousands of tiny polyester fibers and are the next best thing for cleaning your screen if you don’t have a microfiber cloth.

If you ever find yourself questioning the methods by which you plan to clean your laptop screen, it’s best to err on the side of caution. To take extra precaution, you can order specialized products and cleaning solutions online or pick them up at electronic stores.

Compressed gas is one of the best places to start when learning how to clean your laptop. Not only is this product great for removing the dust on your screen, but it’s also good for cleaning your keyboard as well. Dust-Off®, Endust®, and Fellowes® are all solid and reliable brands of compressed air that have withstood the test of time. They are available at grocery stores, drug stores, and computer stores, as well as many online retailers.

Bryson Screen and Laptop Cleaner is a reasonably inexpensive cleaning solution that’s as easy to use. Just spray it onto a screen-safe cleaning cloth and wipe away all of your worries.

The i-ScreenClean Ball 3-Pack is a great tool for daily cleaning and maintenance. With the i-ScreenClean ball, you can entirely avoid the use of liquids while you clean your laptop screen or monitor. Bigger problems like spills and stains will require the use of professional cleaning products, but for the most part, the cleaning ball is a great way to go.

The corners of your monitor or laptop screen are often the most difficult and frustrating to clean. Fortunately, cleaning brushes for detailing are available. The Oxo Good Grips cleaning brush is perfect for reaching into the corners of your laptop’s display. This tool will allow you to avoid the use of liquids and give your laptop a complete clean.

You can find most of these products online or at computer stores along with wipes and other cleaning supplies that were specifically designed for laptop screens and monitors.

Once you’ve cleaned your laptop screen, try to keep it that way. One of the primary reasons your screen continues to get dirty so often is because of your keyboard. Dead skin cells, dirt, and grime from your fingertips get on the keyboard and transfers to your laptop’s screen when you close it.

One of the best ways to prevent this transference of dirt and grime is to place a thin microfiber cloth on top of your keyboard every time you close your computer.

If you know that you’re not going to use your laptop for an extended period, be sure to keep it stored in a sealed computer bag or plastic bag. Dust and dirt can easily build up in a matter of days if your laptop is left out in in the open. You should always store your laptop whenever you’re not using it; doing so will prevent dust from building up inside the hardware.

The best thing about touch screens, especially tablets and smartphones, is that they usually come with an additional protective screen that makes it much easier to clean. However, you should still take the same precautions that you would with a standard laptop screen.

While touch screen laptops aren’t always made of the same materials that traditional smartphones and tablets are, they may often be just as sensitive. The best thing to do is pick up a microfiber cloth and give your screen a gentle wipe down using the same techniques previously mentioned.

Unless you plan to wash your hands before each time you use your touch screen laptop, you should make an effort to clean it far more frequently. All that grime on your fingertips dragging across your screen can cause a major build up.

Touch screens are especially sensitive to pressure, so make sure you don’t press down too firmly while you’re cleaning since it could wear out the sensors or even damage them. You will also want to turn your screen off before cleaning. You wouldn’t want to accidentally send out a strange jumbled-up email to an important client while you’re cleaning.

When learning how to clean your monitor or laptop screen, it’s always better to be safe than sorry. You invested a significant amount in your laptop and other electronics. It would be wise to invest a small amount in their care and upkeep. Investing in a microfiber cloth that you keep in your desk just for your laptop, along with a cleaning solution kit might cost you a few bucks but it will cost you far more to replace a damaged computer screen from careless cleaning.

Important technical improvements of LCD, such as LED backlighting and wide viewing Angle, are directly related to LCD. And account for an LCD display 80% of the cost of the LCD panel, enough to show that the LCD panel is the core part of the entire display, the quality of the LCD panel, can be said to directly determine the quality of an LCD display.

The production of civil LCD displays is just an assembly process. The LCD panel, the main control circuit, shell, and other parts of the main assembly, basically will not have too complex technical problems.

Does this mean that LCDS are low-tech products? In fact, it is not. The production and manufacturing process of the LCD panels is very complicated, requiring at least 300 process processes. The whole process needs to be carried out in a dust-free environment and with precise technology.

The general structure of the LCD panel is not very complex, now the structure of the LCD panel is divided into two parts: the LCD panel and the backlight system.

Due to the LCD does not shine, so you need to use another light source to illuminate, the function of the backlight system is to this, but currently used CCFL lamp or LED backlight, don’t have the characteristics of the surface light source, so you need to guide plate, spreadsheet components, such as linear or point sources of light evenly across the surface, in order to make the entire LCD panel on the differences of luminous intensity is the same, but it is very difficult, to achieve the ideal state can be to try to reduce brightness non-uniformity, the backlight system has a lot to the test of design and workmanship.

In addition, there is a driving IC and printed circuit board beside the LCD panel, which is mainly used to control the rotation of LCD molecules in the LCD panel and the transmission of display signals. The LCD plate is thin and translucent without electricity. It is roughly shaped like a sandwich, with an LCD sandwiched between a layer of TFT glass and a layer of colored filters.

LCD with light refraction properties of solid crystals, with fluid flow characteristics at the same time, under the drive of the electrode, can be arranged in a way that, in accordance with the master want to control the strength of the light through, and then on the color filter, through the red, green, blue three colors of each pixel toning, eventually get the full-screen image.

According to the functional division, the LCD panel can be divided into the LCD panel and the backlight system. However, to produce an LCD panel, it needs to go through three complicated processes, namely, the manufacturing process of the front segment Array,the manufacturing process of the middle segment Cell, and the assembly of the rear segment module. Today we will be here, for you in detail to introduce the production of the LCD panel manufacturing process.

The manufacturing process of the LCD panel Array is mainly composed of four parts: film, yellow light, etch and peel film. If we just look at it in this way, many netizens do not understand the specific meaning of these four steps and why they do so.

First of all, the motion and arrangement of LCD molecules need electrons to drive them. Therefore, on the TFT glass, the carrier of LCD, there must be conductive parts to control the motion of LCD. In this case, we use ITO (Indium Tin Oxide) to do this.ITO is transparent and also acts as a thin-film conductive crystal so that it doesn’t block the backlight.

The different arrangement of LCD molecules and the rapid motion change can ensure that each pixel displays the corresponding color accurately and the image changes accurately and quickly, which requires the precision of LCD molecule control.ITO film needs special treatment, just like printing the circuit on the PCB board, drawing the conductive circuit on the whole LCD board.

First, the ITO film layer needs to be deposited on the TFT glass, so that there is a smooth and uniform ITO film on the whole TFT glass. Then, using ionized water, the ITO glass is cleaned and ready for the next step.

Next, a photoresist is applied to the glass on which ITO film is deposited, and a uniform photoresist layer is formed on the ITO glass. After baking for a period of time, the solvent of the photoresist was partially volatilized to increase the adhesion of the photoresist material to the ITO glass.

Ultraviolet light (UV) is used to illuminate the surface of the photoresist through a pre-made electrode pattern mask, which causes the photoresist layer to react. The photoresist is selectively exposed under ultraviolet light by covering the photoresist on the glass coated with the photoresist.

The exposed part of the photoresist is then washed away with the developer, leaving only the unexposed part, and the dissolved photoresist is then washed away with deionized water.

Then etch off the ITO film without photoresist covering with appropriate acid etching solution, and only retain the ITO film under the photoresist. ITO glass is conductive glass (In2O3 and SnO2). The ITO film not covered by photoresist is easy to react with acid, while the ITO film covered by photoresist can be retained to obtain the corresponding wire electrode.

Stripping: High concentration of alkali solution (NaOH solution) is used as a stripping solution to peel off the remaining photoresist on the glass so that ITO glass can form ITO graphics exactly consistent with the photolithography mask.

Rinse the basic label of glass with an organic solution and remove the photolithographic tape after reaction to keep the glass clean. This completes the first thin-film conductive crystal process, which generally requires at least five identical processes to form a complex and sophisticated pattern of electrodes on the glass.

This completes the previous Array process. It is not difficult to see from the whole process that ITO film is deposited, photoresist coated, exposed, developed, and etched on TFT glass, and finally, ITO electrode pattern designed in the early stage is formed on TFT glass to control the movement of LCD molecules on the glass. The general steps of the whole production process are not complicated, but the technical details and precautions are very complicated, so we will not introduce them here. Interested friends can consult relevant materials by themselves.

The glass that the LCD board uses makes a craft also very exquisite. (The manufacturing process flow of the LCD display screen)At present, the world’s largest LCD panel glass, mainly by the United States Corning, Japan Asahi glass manufacturers, located in the upstream of the production of LCD panel, these manufacturers have mastered the glass production technology patents. A few months ago, the earthquake caused a corning glass furnace shutdown incident, which has caused a certain impact on the LCD panel industry, you can see its position in the industry.

As mentioned earlier, the LCD panel is structured like a sandwich, with an LCD sandwiched between the lower TFT glass and the upper color filter. The terminal Cell process in LCD panel manufacturing involves the TFT glass being glued to the top and bottom of a colored filter, but this is not a simple bonding process that requires a lot of technical detail.

As you can see from the figure above, the glass is divided into 6 pieces of the same size. In other words, the LCD made from this glass is finally cut into 6 pieces, and the size of each piece is the final size. When the glass is cast, the specifications and sizes of each glass have been designed in advance.

Then, the organic polymer directional material is coated on the surface of the glass, that is, a uniform directional layer is applied to the appropriate position of ITO glass by the method of selective coating. Meanwhile, the directional layer is cured.

Directional friction:Flannelette material is used to rub the surface of the layer in a specific direction so that the LCD molecules can be arranged along the friction direction of the aligned layer in the future to ensure the consistency of the arrangement of LCD molecules. After the alignment friction, there will be some contaminants such as flannelette thread, which need to be washed away through a special cleaning process.

After the TFT glass substrate is cleaned, a sealant coating is applied to allow the TFT glass substrate to be bonded to the color filter and to prevent LCD outflow.

Finally, the conductive adhesive is applied to the frame in the bonding direction of the glass of the color filter to ensure that external electrons can flow into the LCD layer. Then, according to the bonding mark on the TFT glass substrate and the color filter, two pieces of glass are bonded together, and the bonding material is solidified at high temperatures to make the upper and lower glasses fit statically.

Color filters are very important components of LCD panels. Manufacturers of color filters, like glass substrate manufacturers, are upstream of LCD panel manufacturers. Their oversupply or undersupply can directly affect the production schedule of LCD panels and indirectly affect the end market.

As can be seen from the above figure, each LCD panel is left with two edges after cutting. What is it used for? You can find the answer in the later module process

Finally, a polarizer is placed on both sides of each LCD substrate, with the horizontal polarizer facing outwards and the vertical polarizer facing inwards.

A polarizer is an optical plate that allows only light from a certain direction to pass through. It is an optical element that converts natural light into straight polarized light. The mechanism of action is to make the vertical direction light pass through the straight incident light after passing through the vertical polarizer, and the other horizontal direction light is absorbed, or use reflection and scattering and other effects to make its shade.

When making LCD panel, must up and down each use one, and presents the alternating direction, when has the electric field and does not have the electric field, causes the light to produce the phase difference and to present the light and dark state, uses in the display subtitle or the pattern.

The rear Module manufacturing process is mainly the integration of the drive IC pressing of the LCD substrate and the printed circuit board. This part can transmit the display signal received from the main control circuit to the drive IC to drive the LCD molecules to rotate and display the image. In addition, the backlight part will be integrated with the LCD substrate at this stage, and the complete LCD panel is completed.

Firstly, the heteroconductive adhesive is pressed on the two edges, which allows external electrons to enter the LCD substrate layer and acts as a bridge for electronic transmission

Next is the drive IC press. The main function of the drive IC is to output the required voltage to each pixel and control the degree of torsion of the LCD molecules. The drive IC is divided into two types. The source drive IC located in the X-axis is responsible for the input of data. It is characterized by high frequency and has an image function. The gate drive IC located in the Y-axis is responsible for the degree and speed of torsion of LCD molecules, which directly affects the response time of the LCD display. However, there are already many LCD panels that only have driving IC in the X-axis direction, perhaps because the Y-axis drive IC function has been integrated and simplified.

The press of the flexible circuit board can transmit data signals and act as the bridge between the external printed circuit and LCD. It can be bent and thus becomes a flexible or flexible circuit board

The manufacturing process of the LCD substrate still has a lot of details and matters needing attention, for example, rinse with clean, dry, dry, dry, ultrasonic cleaning, exposure, development and so on and so on, all have very strict technical details and requirements, so as to produce qualified eyes panel, interested friends can consult relevant technical information by a search engine.

LCD (LC) is a kind of LCD, which has the properties of light transmission and refraction of solid Crystal, as well as the flow property of Liquid. It is because of this property that it will be applied to the display field.

However, LCD does not emit light autonomously, so the display equipment using LCD as the display medium needs to be equipped with another backlight system.

First, a backplate is needed as the carrier of the light source. The common light source for LCD display equipment is CCFL cold cathode backlight, but it has started to switch to an LED backlight, but either one needs a backplate as the carrier.

CCFL backlight has been with LCD for a long time. Compared with LED backlight, CCFL backlight has many defects. However, it has gradually evolved to save 50% of the lamp and enhance the transmittance of the LCD panel, so as to achieve the purpose of energy-saving.

With the rapid development of LED in the field of lighting, the cost has been greatly reduced.LCD panels have also started to use LED as the backlight on a large scale. Currently, in order to control costs, an LED backlight is placed on the side rather than on the backplate, which can reduce the number of LED grains.

However, no matter CCFL backlight or LED backlight is placed in various ways, the nature of the backlight source cannot be a surface light source, but a linear light source or point light source. Therefore, other components are needed to evenly distribute the light to the whole surface. This task is accomplished by the diffuser plate and diffuser plate.

On the transparent diffuser plate, point-like printing can block part of the light. The LED backlight on the side drives the light from the side of the diffuser plate, and the light reflects and refracts back and forth in the diffuser plate, distributing the light evenly to the whole surface. Point-like printing blocks part of the light, screening the light evenly like a sieve.

At the top of the diffusion plate, there will be 3~4 diffuser pieces, constantly uniform light to the whole surface, improve the uniformity of light, which is directly related to the LCD panel display effect. Professional LCD in order to better control the brightness uniformity of the screen, panel procurement, the later backlight control circuit, will make great efforts to ensure the quality of the panel.

The backlight system also includes a backlight module laminator, located behind the backplane. In the CCFL backlight era, you can often see the long strip laminator like the one above, with each coil responsible for a set of tubes.

However, it is much simpler to use a side white LED as a backlight. The small circuit board on the far left of the figure above is the backlight of the LED.

This is the general structure of the backlight system. Since I have never seen the backlight mode of R.G.B LED, I cannot tell you what the backlight mode is like. I will share it with you when I see it in the future.

Since the LCD substrate and the backlight system are not fixed by bonding, a metal or rubber frame is needed to be added to the outer layer to fix the LCD substrate and the backlight system.

After the period of the Module, the process is completed in LCM (LCDModule) factory, the core of this part of the basic does not involve the use of LCD manufacturing technology, mainly is some assembly work, so some machine panel factories such as chi mei, Korea department such as Samsung panel factory, all set with LCM factories in mainland China, Duan Mo group after the LCD panel assembly, so that we can convenient mainland area each big monitor procurement contract with LCD TV manufacturers, can reduce the human in the whole manufacturing and transportation costs.

However, neither Taiwan nor Korea has any intention to set up factories in mainland China for the LCD panel front and middle manufacturing process involving core technologies. Therefore, there is still a long way to go for China to have its own LCD panel industry.

Nowadays with the rise of the Chinese phone, LED TVs, laptops, Notebooks, phablets, portable DVD players and so many other gadgets,  LCD screens are everywhere.

While their tube counterparts are basically special windows that can be cleaned in much the same way we do our windows, LCD screens require special attention. Improper cleaning may result in a serious financial expenditure in the form of a new screen as I recently learnt the hard way.

LCDs are made of a material that is thin and susceptible to scratching. Using the same material that you use for cleaning windows and old school screens may result in the screen getting damaged or scratched.

Power off the device be it a laptop, TV, tablet or phone. You should also unplug it if possible. Doing this reduces the risks of electrical shock, an electrical mishap because of liquids spilling into the device and makes it easier for you to see the dirt on the screen.

Using a non-abrasive soft cloth gently wipe the dust off the screen. Do not apply excessive pressure in an attempt to remove stubborn smudges such as those from finger prints. These can be removed later using a cleaning solution. You can buy micro-fiber cloth from opticians’ shops or perhaps computer shops. I couldn’t find it in these and found the fiber sold by opticians to be too small. The fiber is used to clean spectacles. I use my old Econet cotton T-shirt which is ideally soft. You can use a soft cotton T-shirt or handkerchief. Just make sure that it does not leave bits of lint behind as this makes cleaning difficult.

Mix a solution of 50% water and 50% white vinegar to use as a cleaning solution. Vinegar is available in most supermarkets. It is also preferable to use distilled water which you can obtain from pharmacies, battery shops or you could use bottled water as it is cleaner than tap water. Avoid the filthy poison that comes out of our taps by all means. Do not use Windowlene.

Gently wipe off the smudges and grime on the screen working in a circular motion. Avoid pressing into the monitor. Do not scrape the stubborn smudges just allow the cleaner to penetrate and dissolve them then gently wipe them away.

Touchscreens can handle much more abuse than TV and laptop screens so the later should be treated with care. I routinely used Windolene on my own laptop screen for years until a couple of weeks the screen just turned white. I had to pay through the nose to replace it. So just because your cleaning method has not yet ruined your screen does not mean you should continue using it. You have been warned.
