best way to clean lcd screen made in china

Remember when your LCD or OLED display had that brand-new, fresh-out-of-the-box shine, feel and look? You are in the right place if your display is now due for deep cleaning.

Things to consider before cleaning or handling an electronic displayAvoid static by grounding your body and following proper ESD-safe handling techniques.

A microfiber cloth and distilled water is recommended for cleaning the display glass. Use Qtips and Isopropyl alcohol for cleaning the printed circuit board.

Although distilled water is recommended for wiping the display glass, you can use a cleanser developed explicitly for cleaning displays. However, do not spray it directly onto the display. Spray a tiny amount of the cleaner onto a microfiber cloth first to avoid getting any cleaning solution inside the display.Never spray any liquids directly onto the display.A spray is too hard to control and confine. The fluids can seep into the other display layers or surrounding components and cause irreversible liquid damage.

Only use a microfiber cloth and don"t use chemicals to clean a resistive touchscreen.Disconnect the display from the power supply and remove any screen protectors or liners.

Isopropyl alcohol (IPA) is widely used to clean printed circuit boards (PCBs). Use a Q-tip or soft small bristle brush for scrubbing a PCB, and never use a paintbrush.Gently rub a Q-tip in Isopropyl alcohol.

Cleaning soldering residue on LCD with Isopropyl alcohol and a Q-Tip.Cleaning residue around soldering elements is not necessary if Newhaven Display performed the soldering.

Cleaning your electronic display is a simple task. However, it is essential to consider these steps to handle and clean it properly. You should now have a better understanding of what cleaning products are safe to use, how to clean the display screen glass, how to clean touchscreens and how to clean soldering residue.

LCD Displays are interfaces of human and machine. They expose to various environments, especially now that COVID-19 spreading around the world. So it"s impossible to keep a screen clean all the time. When you are going to clean an LCD display，do you have the right steps in mind？Maybe what you"ve been doing is not right！

LCD screens could have different top layers. For example, there are glass, plastic, coating, or protective bezels. Each one of them is different. Therefore, each type of screen should not be cleaned in only one way. In fact, the most appropriate way is written in product manual. Take Topway HMT070ETD-1D, a 7 inch Smart TFT LCD Display with capacitive touch screen, as an example. Cleaning precautions are as follow: Only clean LCD with a soft dry cloth. Isopropyl Alcohol or Ethyl Alcohol. Other solutions(e. g. water) may damage the LCD.

LCD screens are fragile. Before cleaning an LCD display, you should turn it off completely, disconnect it from power supply,  and let it cool down for a few minutes. This will eliminate danger of electrocution and make it easier to see dust on screen.

Don’t press down hard while cleaning, because that action may damage top layers or coating. Spray a little cleaning solution, such as isopropyl alcohol diluted with either pure or distilled water, onto a microfiber cloth and gently wipe the display in either an up and down or side to side motion. Too much pressure can compromise limited durability of even the most rugged LCD screens.

There are a few types of cloth can be used. Microfiber is recommended. It is lightweight and soft, seldom produces loose fiber. Because of an intricate way in which minuscule fibers are intertwined, microfiber is able to remove large amounts of dirt and dust without leaving streaks or lint. You can also use a cotton cloth if you don’t have a microfiber one on hand.

It is dangerous that an LCD display directly contacts with any liquids (especially when they’re still plugged in). A safer and smarter approach is to first wipe the screen with a dry cloth, then spray a small amount of cleaning solution onto another cloth and wipe gently. After that, wipe with another clean, dry cloth to remove the residual liquid.

Never use ammonia or rubbing alcohol based cleaners on LCD screens. They will damage the extremely delicate coating on top of screens, and negatively alter viewing experience, especially in strong sunlight.

Dust in gaps where bezels and top layers meet can cause internal damage to LCD displays. Regularly using a vacuum with a soft-bristled brush (to prevent scratching) can be helpful.

Now you know how to clean an LCD screen safely and correctly, if you find it helpful, please share this article with your friends. If there are more questions about LCD displays, please feel free to leave us a message.

Follow the steps below to safely clean your flat screen monitor, TV, laptop screen, or other device in just a few minutes. This information applies to televisions from manufacturers including LG, Samsung, Panasonic, Sony, and Vizio.

Turn off the device. If the screen is dark, it will be easier to see the areas that are dirty or oily. Turning the device off also prevents you from accidentally pushing buttons you don"t actually want to push, which happens a lot when cleaning touchscreen devices like tablets, iPads, etc.

If the dry cloth did not completely remove the dirt or oil, do not press harder in an attempt to scrub it off. Pushing directly on the screen can often cause pixels to burn out, especially on laptop displays, desktop monitors, and LCD/LED TV screens.

If necessary, dampen the cloth with distilled water or with an equal ratio of distilled water to white vinegar. Many companies also sell small spray bottles of special cleaner for flat screens.

Avoid using paper towels, toilet paper, tissue paper, rags, or something like your shirt to wipe the screen. These non-ultrasoft materials can scratch the display.

Avoid cleaning products that contain ammonia (like Windex®), ethyl alcohol (Everclear® or other strong drinking alcohol), toluene (paint solvents), as well as acetone or ethyl acetate (one or the other is often used in nail polish remover).

These chemicals can react with the materials that the flat screen is made of or coated with, which could permanently discolor the screen or cause other kinds of damage.

Never spray liquid directly onto the screen. It could leak into the device and cause damage. Be sure to always put the cleaning solution directly onto the cloth and then wipe from there.

These same cleaning "rules" apply no matter if your TV is 8K, 4K, or 1080p (HD). Those differences don"t mean the display is necessarily made out of anything different, requiring different cleaning, it"s just a measure of how many pixels per inch they shoved in the same space.

If you"re cleaning your TV because it appears dirty, but then find that the screen is actually physically damaged, you might be ready for a new HDTV. See our Best TVs to Buy list for our top suggestions, or this Best Cheap TVs list for some budget-friendly HDTVs.

Plasma TVs are glass, as are many touchscreens, but often also have very sensitive anti-glare coatings applied. Take the same special care with those types of displays.

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.

What can be better after a long day’s work than lying down on a sofa watching TV? The television can become our best friend to relieve the pressure from work, relationships, and annoying relatives. LCD TV displays as added “member” of the family also need to be taken care of. For this reason, it is recommended to regularly clean the LCD screen as dust and dirt may affect its performance. What we are trying to say is that if the television is too dirty, you won’t be enjoying your favorite program. Trust me! you do not want that…

How can we clean the LCD Display? This is a concern for many people. Before we find out the answer, we need to know what to avoid. Here, please do not take out your t-shirt and wipe the screen from those beer stains, calm down, and hear me out. Many people would easily make mistakes in solving this problem even without consciousness. So let’s take a look at some wrong cleaning methods first: Wiping the LCD Screen directly with the palm or fingers

You should know that LCD should not be touched. When rubbing with the palm or fingers, it is difficult to use the right amount of force. If the force is too strong, it may cause permanent damage to the liquid crystal molecules, which translate into watching at a multicolor liquid stain on your TV instead of your favorite show. Wipe the LCD screen with a rough towel

Someone may directly clean the LCD display with the towel used to wipe the table at home. However, this is a wrong behavior as you can scratch the surface or get the screen even dirtier. Do not also use paper towels, toilet paper, or old T-shirts. These materials are abrasive and leave a lot of residues.

Now that we know what we should not do, let us move with the proper cleaning methods. First of all, let us briefly explain the LCD TV display structure. The LCD panel is mainly composed of two sodium-free glass sandwiched by a polarizer, a liquid crystal layer, and a color filter. Feeling confused? check here our article about LCD TVdisplays.

Moving on to the cleaning. Well, the first thing you should do is to turn off your television. I know it seems obvious to say, but many people do not follow this step. After that, you have two main choices: standard or creative method:

The first being the standard option, is the most formal and troublesome. Stand up and go out buying the special LCD cleaner and microfiber cloth to clean the LCD screen. If you are too lazy, you can order it online. Although this method is effective, it implies that you need to buy the cleaning agent and my friend, depending on how regularly you clean, it can be expensive. Once bought the products, apply the cleaning agent to the cloth and gently wipe the entire surface of the LCD TV display, removing any visible traces of dirt and dust.

If you thought it was too easy after hearing the standard option, or those nasty stains are still there, we have the solution for you. Here we share the “creative” method.

Prepare a liquid solution using equal amounts of vinegar and water. Vinegar is a natural and safe detergent and is much cheaper than the products on the market, specially designed for cleaning televisions.

Dampen the microfiber cloth in the vinegar and water solution and then wipe your TV screen softly. If necessary, apply gentle pressure and a circular motion to the spots where you notice stubborn stains. Keep in mind not to spray the vinegar solution directly on the TV screen, as you could damage it irreparably.

Following, use a second microfiber cloth to dry the TV screen. Pay attention not to allow the screen to air dry. Otherwise, annoying halos may remain and influence image quality.

Finally, wash the plastic frame of the TV. If the frame also requires a more intensive cleaning, use some paper towels after wetting it in the vinegar and water solution. Use paper towels to dry it completely.

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.

The way you clean your computer screen largely depends on what it"s made of - you have to be more careful with LED/LCD screens than glass-coated ones.

We"ve all had that moment - you"re sitting at your desk on a normal workday, then the sun starts shining directly on your screen, and you realize you don"t know when you last cleaned it. In fact, it may have been so long that you"ve forgotten how you"re supposed to clean it.

If this sounds like you, don"t feel too bad - most experts recommend that you should only clean your computer screen every three to six months. So if you"ve waited half a year since the last time you cleaned, it makes sense that you might not remember all the do"s and don"ts of the process.

Here"s a helpful guide to help you remember exactly how to clean your specific computer screen, whether it"s a Mac or PC, including which products you should and shouldn"t use for your specific type of display.

Glass-coated screens: The screens you find on most Mac computers are glass-coated. Displays like this are a little less delicate than LED or LCD screens.

LED/LCD screens: These screens are mostly found on Windows computers. Unlike glass-coated screens, they"re made up of tiny liquid crystals and can be very easily damaged if you"re not careful. Most touchscreens and matte displays are LED/LCD.

You may want to look on your manufacturer"s website and check what kinds of solutions are safe for the screen type you have - factors like whether your screen is matte or a touchscreen may affect this.

If you have a glass-coated screen on your computer, you have a few more options as to what cleaners you can use, but you should still be careful. You can use one of the solutions listed above, but you can also use:

Turn off your computer before cleaning - this is just safe practice where any amount of liquid is involved, but more specifically, any static on the screen could create a shock and damage the internal components.

Use filtered or distilled water if you need to use it, especially in areas with hard water - minerals like calcium and magnesium in the water you use could also damage your screen.

Wipe in tight, Z-shaped motions, or directly up and down or side to side. Wiping in circles can create uneven pressure and ultimately lead to screen damage. It"s also more likely to create streaking.

Use any fabric that feels rough to the touch - even a fabric as soft as a cotton shirt has snags and uneven parts that can damage a computer screen. Microfiber cloths are ideal because the fibers are so tiny that they can cover every inch of the screen with even pressure at the same time, eliminating any opportunity for scratches.

Spray any cleaning solution directly onto the screen. To avoid any risk of damage from excess moisture, spray the solution directly onto the microfiber cloth instead.

Apply pressure when you clean the screen. This will likely damage the internal components of the screen and could leave scratches or spots of discoloration or dead pixels that won"t go away.

Even if you"re working on a particularly stubborn spot, don"t scrub - rather, leave the damp cloth sitting on the screen for several minutes, then try to gently wipe it away again.

Once you"ve turned off your computer and dusted off the screen, mist a dust-free side of your microfiber cloth with a cleaning solution that is safe for the type of screen you have.

Wipe the screen in a consistent, non-circular motion without applying too much pressure. Make sure no moisture accumulates, especially at the corners - if it does, use a dry corner of microfiber cloth to gently wipe it away.

Don"t make the mistake of thinking that LCD screens work like your nifty new iPad. In general, touching should be off limits because pressing too hard on the screen can actually break or crack pixels. So the first rule to cleaning an LCD screen is don"t do it unless you have to (i.e. unless it"s actually dirty).

Many retailers offer special cleaning solutions for LCD screens, but the truth is that most of these are made up primarily of water. So, if you don"t want to take the time to go buy a cleaner or you want to save the money (maybe to put toward that "What Not to Wear" dress), you can just make your own LCD cleaner by mixing water with some vinegar or isopropyl alcohol -- the solution should be no more than 50/50.

You could even start with plain water and see if you need the vinegar or alcohol, which will come in handy when you"re trying to wipe away greasy fingerprints. Some people recommend only using distilled water, but regular water works fine, according to Dave Chipman from Sharp.

Unless you want to end up with a melted, discolored, hazy or scratched LCD screen, steer clear of all spray cleaners. In particular, don"t use any solvent cleaners that include acetone, ethyl alcohol, ethyl acid, ammonia or methyl chloride. You also want to avoid using any materials that could potentially scratch the screen"s delicate surface. Opt for a soft, clean, cotton cloth instead of wood-based products like paper towels and tissues. Chipman suggests using a microfiber cloth for best results.

If you"re lucky enough to have a service come in and do your cleaning for you, make sure they don"t inadvertently ruin your television or monitor by trying to clean it with something like glass cleaner. You should either take the time to explain -- and maybe even demonstrate -- how you want your LCD screen cleaned or just ask your cleaner to leave this particular job for you.

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.

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.

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.

A.The input of ITO glass: According to the requirements of the product, appropriate ITO glass is selected and put into the transfer basket. Specifications and models of ITO glass are required to meet the requirements of the product. Remember that the ITO layer must be inserted into the basket upward.

B. Cleaning and drying of glass: Clean ITO glass with the cleaning agent and deionized water (DI water), wash impurities and oil stains on the ITO surface with physical or chemical methods and then remove and dry the water to ensure the processing quality of the next process.

C.Photoresist coating: Evenly coat a layer of photoresist on the conductive surface of ITO glass. The glass coated with photoresist must be pretreated at a certain temperature: (as shown in the figure below)

D.Pre-drying: The glass coated with a photoresist is baked for a period of time at a certain temperature to volatilize the solvent in the photoresist and increase its adhesion to the glass surface.

E.Exposure: Ultraviolet light (UV) is used to illuminate the surface of the photoresist through the pre-made electrode pattern mask, which causes the reaction of the photoresist layer. The photoresist is selectively exposed under an ultraviolet lamp by covering the photoresist on the glass coated with the photoresist (as shown in the figure).

F.Development: the surface of the glass is treated with developer solution, the photoresist layer decomposed by light is removed, the photoresist layer of the unexposed part is retained, the photoresist of the part exposed by UV light is dissolved in the developer solution by chemical method, the developed glass has to undergo a certain temperature hardening film treatment.

H.Etching: With appropriate acid etching solution, the ITO film without photoresist covering is etched off. Thus, the required ITO electrode pattern is obtained.

Note:is conductive glass (In2O3 and SnO2), which is easy to react with acid and is used to etch off the excess ITO to obtain the corresponding wire electrode.

I.Film removal: the high concentration of alkali solution (NaOH solution) is used as the film removal solution to peel off the remaining photoresist on the glass, thus forming ITO graphics exactly consistent with the lithography mask on the ITO glass.

General TN and the STN product does not require this step, the TOP film coating process is after the photolithography process making SiO2 coating, once again to the etching area and the etching area between the grooved bridge and the electrode covering, this can have the effect of the insulation layer, and can effectively eliminate the display state of the bottom electrode, also help to improve the perspective characteristics and so on, so most of the high-grade product requires TOP coating.

This process involves coating an oriented layer on the etched ITO glass surface and treating the restricted layer in a specific way so that the liquid crystal molecules can be oriented (arranged) in a specific direction on the surface of the oriented layer. This step is unique to the production of liquid crystal displays.

Organic polymer-oriented material is coated on the surface of the glass, that is, a uniform orientation layer is applied to the appropriate position of ITO glass by a selective coating method, and the orientation layer is cured at the same time. (Usually in the display area)

Flannelette material is used to rub the surface of the oriented layer in a specific direction so that the liquid crystal molecules can be arranged along the friction direction of the oriented layer in the future. For example, TN type friction orientation: 45 degrees

In this process, two conductive glasses are stacked on top of each other, and sealed together, and cured to make a glass box with a specific thickness of clearance. The technology of box-making is one of the key technologies in LCD manufacturing. (Spacing of LIQUID crystal boxes must be strictly controlled)

Evenly distribute the supporting material over the lower glass. A certain size of the liner (usually a few microns) is evenly distributed over the surface of the glass. These materials are used to ensure that the spacing between the glasses is the thickness of the box.

press the upper and lower glass against each other on the counterpoint mark, and then glue the corresponding two pieces of glass face to face with sealing material.

Curing the sealing material at high temperatures. When curing, the pressure is applied to the upper and lower glass to make the spacing of the liquid crystal boxes (thickness remains uniform).
