what do you clean an lcd screen with made in china

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.

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.

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.

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.

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.

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.

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.

Effective for cleaning TV screens, computer monitors, laptop screens, cell phone screens, telephones, and keyboards. 8242-W Wipes remove dust, dirt, grease, oily residues, fingerprints, and smoke films.

Repair guides can be hard to find. I"ve only seen guides for iMac but the general idea is the same. Remove the LCD assembly from the housing, remove the fixture tapes and side frames from the assembly, lift the panel and clean it. It seems that soft cloth is enough to clean the panels. Be aware of additional dust when wiping the panels and wipe gently, you may scarch the panel in the process if not careful enough. Make sure you seal the assembly well to prevent further dust.

It IS a very difficult repair, the assembly is very heavy, maybe more than 2/3 of the unit"s total weight, and it is a fragile piece of art. Several cables and sensors attach to the back side of the panel. You can easily damage them when lifting the LCD. There are many clips locking the frame. Quite tricky to remove. And at last the LCD driver board is connected to the panel by several ribbon cables. You must not tear any one of them or the entire unit is totaled. In conclusion, very challenging to do so.

Whether it is a computer display screen or a TV screen, after they have used it for a period of time, the screen will be covered with a lot of dust because of static electricity. Although this does not have much impact on the use, if the dust is too thick, it still needs a good wipe. So, how to clean the

Glass substrate with ITO electrodes. The shapes of these electrodes will determine the shapes that will appear when the LCD is switched ON. Vertical ridges etched on the surface are smooth.

A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directlybacklight or reflector to produce images in color or monochrome.seven-segment displays, as in a digital clock, are all good examples of devices with these displays. They use the same basic technology, except that arbitrary images are made from a matrix of small pixels, while other displays have larger elements. LCDs can either be normally on (positive) or off (negative), depending on the polarizer arrangement. For example, a character positive LCD with a backlight will have black lettering on a background that is the color of the backlight, and a character negative LCD will have a black background with the letters being of the same color as the backlight. Optical filters are added to white on blue LCDs to give them their characteristic appearance.

LCDs are used in a wide range of applications, including LCD televisions, computer monitors, instrument panels, aircraft cockpit displays, and indoor and outdoor signage. Small LCD screens are common in LCD projectors and portable consumer devices such as digital cameras, watches, digital clocks, calculators, and mobile telephones, including smartphones. LCD screens are also used on consumer electronics products such as DVD players, video game devices and clocks. LCD screens have replaced heavy, bulky cathode-ray tube (CRT) displays in nearly all applications. LCD screens are available in a wider range of screen sizes than CRT and plasma displays, with LCD screens available in sizes ranging from tiny digital watches to very large television receivers. LCDs are slowly being replaced by OLEDs, which can be easily made into different shapes, and have a lower response time, wider color gamut, virtually infinite color contrast and viewing angles, lower weight for a given display size and a slimmer profile (because OLEDs use a single glass or plastic panel whereas LCDs use two glass panels; the thickness of the panels increases with size but the increase is more noticeable on LCDs) and potentially lower power consumption (as the display is only "on" where needed and there is no backlight). OLEDs, however, are more expensive for a given display size due to the very expensive electroluminescent materials or phosphors that they use. Also due to the use of phosphors, OLEDs suffer from screen burn-in and there is currently no way to recycle OLED displays, whereas LCD panels can be recycled, although the technology required to recycle LCDs is not yet widespread. Attempts to maintain the competitiveness of LCDs are quantum dot displays, marketed as SUHD, QLED or Triluminos, which are displays with blue LED backlighting and a Quantum-dot enhancement film (QDEF) that converts part of the blue light into red and green, offering similar performance to an OLED display at a lower price, but the quantum dot layer that gives these displays their characteristics can not yet be recycled.

Since LCD screens do not use phosphors, they rarely suffer image burn-in when a static image is displayed on a screen for a long time, e.g., the table frame for an airline flight schedule on an indoor sign. LCDs are, however, susceptible to image persistence.battery-powered electronic equipment more efficiently than a CRT can be. By 2008, annual sales of televisions with LCD screens exceeded sales of CRT units worldwide, and the CRT became obsolete for most purposes.

Each pixel of an LCD typically consists of a layer of molecules aligned between two transparent electrodes, often made of Indium-Tin oxide (ITO) and two polarizing filters (parallel and perpendicular polarizers), the axes of transmission of which are (in most of the cases) perpendicular to each other. Without the liquid crystal between the polarizing filters, light passing through the first filter would be blocked by the second (crossed) polarizer. Before an electric field is applied, the orientation of the liquid-crystal molecules is determined by the alignment at the surfaces of electrodes. In a twisted nematic (TN) device, the surface alignment directions at the two electrodes are perpendicular to each other, and so the molecules arrange themselves in a helical structure, or twist. This induces the rotation of the polarization of the incident light, and the device appears gray. If the applied voltage is large enough, the liquid crystal molecules in the center of the layer are almost completely untwisted and the polarization of the incident light is not rotated as it passes through the liquid crystal layer. This light will then be mainly polarized perpendicular to the second filter, and thus be blocked and the pixel will appear black. By controlling the voltage applied across the liquid crystal layer in each pixel, light can be allowed to pass through in varying amounts thus constituting different levels of gray.

The chemical formula of the liquid crystals used in LCDs may vary. Formulas may be patented.Sharp Corporation. The patent that covered that specific mixture expired.

Most color LCD systems use the same technique, with color filters used to generate red, green, and blue subpixels. The LCD color filters are made with a photolithography process on large glass sheets that are later glued with other glass sheets containing a TFT array, spacers and liquid crystal, creating several color LCDs that are then cut from one another and laminated with polarizer sheets. Red, green, blue and black photoresists (resists) are used. All resists contain a finely ground powdered pigment, with particles being just 40 nanometers across. The black resist is the first to be applied; this will create a black grid (known in the industry as a black matrix) that will separate red, green and blue subpixels from one another, increasing contrast ratios and preventing light from leaking from one subpixel onto other surrounding subpixels.Super-twisted nematic LCD, where the variable twist between tighter-spaced plates causes a varying double refraction birefringence, thus changing the hue.

The optical effect of a TN device in the voltage-on state is far less dependent on variations in the device thickness than that in the voltage-off state. Because of this, TN displays with low information content and no backlighting are usually operated between crossed polarizers such that they appear bright with no voltage (the eye is much more sensitive to variations in the dark state than the bright state). As most of 2010-era LCDs are used in television sets, monitors and smartphones, they have high-resolution matrix arrays of pixels to display arbitrary images using backlighting with a dark background. When no image is displayed, different arrangements are used. For this purpose, TN LCDs are operated between parallel polarizers, whereas IPS LCDs feature crossed polarizers. In many applications IPS LCDs have replaced TN LCDs, particularly in smartphones. Both the liquid crystal material and the alignment layer material contain ionic compounds. If an electric field of one particular polarity is applied for a long period of time, this ionic material is attracted to the surfaces and degrades the device performance. This is avoided either by applying an alternating current or by reversing the polarity of the electric field as the device is addressed (the response of the liquid crystal layer is identical, regardless of the polarity of the applied field).

Displays for a small number of individual digits or fixed symbols (as in digital watches and pocket calculators) can be implemented with independent electrodes for each segment.alphanumeric or variable graphics displays are usually implemented with pixels arranged as a matrix consisting of electrically connected rows on one side of the LC layer and columns on the other side, which makes it possible to address each pixel at the intersections. The general method of matrix addressing consists of sequentially addressing one side of the matrix, for example by selecting the rows one-by-one and applying the picture information on the other side at the columns row-by-row. For details on the various matrix addressing schemes see passive-matrix and active-matrix addressed LCDs.

LCDs, along with OLED displays, are manufactured in cleanrooms borrowing techniques from semiconductor manufacturing and using large sheets of glass whose size has increased over time. Several displays are manufactured at the same time, and then cut from the sheet of glass, also known as the mother glass or LCD glass substrate. The increase in size allows more displays or larger displays to be made, just like with increasing wafer sizes in semiconductor manufacturing. The glass sizes are as follows:

Until Gen 8, manufacturers would not agree on a single mother glass size and as a result, different manufacturers would use slightly different glass sizes for the same generation. Some manufacturers have adopted Gen 8.6 mother glass sheets which are only slightly larger than Gen 8.5, allowing for more 50 and 58 inch LCDs to be made per mother glass, specially 58 inch LCDs, in which case 6 can be produced on a Gen 8.6 mother glass vs only 3 on a Gen 8.5 mother glass, significantly reducing waste.AGC Inc., Corning Inc., and Nippon Electric Glass.

The origins and the complex history of liquid-crystal displays from the perspective of an insider during the early days were described by Joseph A. Castellano in Liquid Gold: The Story of Liquid Crystal Displays and the Creation of an Industry.IEEE History Center.Peter J. Wild, can be found at the Engineering and Technology History Wiki.

In 1888,Friedrich Reinitzer (1858–1927) discovered the liquid crystalline nature of cholesterol extracted from carrots (that is, two melting points and generation of colors) and published his findings at a meeting of the Vienna Chemical Society on May 3, 1888 (F. Reinitzer: Beiträge zur Kenntniss des Cholesterins, Monatshefte für Chemie (Wien) 9, 421–441 (1888)).Otto Lehmann published his work "Flüssige Kristalle" (Liquid Crystals). In 1911, Charles Mauguin first experimented with liquid crystals confined between plates in thin layers.

In 1922, Georges Friedel described the structure and properties of liquid crystals and classified them in three types (nematics, smectics and cholesterics). In 1927, Vsevolod Frederiks devised the electrically switched light valve, called the Fréedericksz transition, the essential effect of all LCD technology. In 1936, the Marconi Wireless Telegraph company patented the first practical application of the technology, "The Liquid Crystal Light Valve". In 1962, the first major English language publication Molecular Structure and Properties of Liquid Crystals was published by Dr. George W. Gray.RCA found that liquid crystals had some interesting electro-optic characteristics and he realized an electro-optical effect by generating stripe-patterns in a thin layer of liquid crystal material by the application of a voltage. This effect is based on an electro-hydrodynamic instability forming what are now called "Williams domains" inside the liquid crystal.

The MOSFET (metal-oxide-semiconductor field-effect transistor) was invented by Mohamed M. Atalla and Dawon Kahng at Bell Labs in 1959, and presented in 1960.Paul K. Weimer at RCA developed the thin-film transistor (TFT) in 1962.

In 1964, George H. Heilmeier, then working at the RCA laboratories on the effect discovered by Williams achieved the switching of colors by field-induced realignment of dichroic dyes in a homeotropically oriented liquid crystal. Practical problems with this new electro-optical effect made Heilmeier continue to work on scattering effects in liquid crystals and finally the achievement of the first operational liquid-crystal display based on what he called the George H. Heilmeier was inducted in the National Inventors Hall of FameIEEE Milestone.

In the late 1960s, pioneering work on liquid crystals was undertaken by the UK"s Royal Radar Establishment at Malvern, England. The team at RRE supported ongoing work by George William Gray and his team at the University of Hull who ultimately discovered the cyanobiphenyl liquid crystals, which had correct stability and temperature properties for application in LCDs.

The idea of a TFT-based liquid-crystal display (LCD) was conceived by Bernard Lechner of RCA Laboratories in 1968.dynamic scattering mode (DSM) LCD that used standard discrete MOSFETs.

On December 4, 1970, the twisted nematic field effect (TN) in liquid crystals was filed for patent by Hoffmann-LaRoche in Switzerland, (Swiss patent No. 532 261) with Wolfgang Helfrich and Martin Schadt (then working for the Central Research Laboratories) listed as inventors.Brown, Boveri & Cie, its joint venture partner at that time, which produced TN displays for wristwatches and other applications during the 1970s for the international markets including the Japanese electronics industry, which soon produced the first digital quartz wristwatches with TN-LCDs and numerous other products. James Fergason, while working with Sardari Arora and Alfred Saupe at Kent State University Liquid Crystal Institute, filed an identical patent in the United States on April 22, 1971.ILIXCO (now LXD Incorporated), produced LCDs based on the TN-effect, which soon superseded the poor-quality DSM types due to improvements of lower operating voltages and lower power consumption. Tetsuro Hama and Izuhiko Nishimura of Seiko received a US patent dated February 1971, for an electronic wristwatch incorporating a TN-LCD.

In 1972, the concept of the active-matrix thin-film transistor (TFT) liquid-crystal display panel was prototyped in the United States by T. Peter Brody"s team at Westinghouse, in Pittsburgh, Pennsylvania.Westinghouse Research Laboratories demonstrated the first thin-film-transistor liquid-crystal display (TFT LCD).high-resolution and high-quality electronic visual display devices use TFT-based active matrix displays.active-matrix liquid-crystal display (AM LCD) in 1974, and then Brody coined the term "active matrix" in 1975.

In 1972 North American Rockwell Microelectronics Corp introduced the use of DSM LCDs for calculators for marketing by Lloyds Electronics Inc, though these required an internal light source for illumination.Sharp Corporation followed with DSM LCDs for pocket-sized calculators in 1973Seiko and its first 6-digit TN-LCD quartz wristwatch, and Casio"s "Casiotron". Color LCDs based on Guest-Host interaction were invented by a team at RCA in 1968.TFT LCDs similar to the prototypes developed by a Westinghouse team in 1972 were patented in 1976 by a team at Sharp consisting of Fumiaki Funada, Masataka Matsuura, and Tomio Wada,

In 1983, researchers at Brown, Boveri & Cie (BBC) Research Center, Switzerland, invented the passive matrix-addressed LCDs. H. Amstutz et al. were listed as inventors in the corresponding patent applications filed in Switzerland on July 7, 1983, and October 28, 1983. Patents were granted in Switzerland CH 665491, Europe EP 0131216,

The first color LCD televisions were developed as handheld televisions in Japan. In 1980, Hattori Seiko"s R&D group began development on color LCD pocket televisions.Seiko Epson released the first LCD television, the Epson TV Watch, a wristwatch equipped with a small active-matrix LCD television.dot matrix TN-LCD in 1983.Citizen Watch,TFT LCD.computer monitors and LCD televisions.3LCD projection technology in the 1980s, and licensed it for use in projectors in 1988.compact, full-color LCD projector.

In 1990, under different titles, inventors conceived electro optical effects as alternatives to twisted nematic field effect LCDs (TN- and STN- LCDs). One approach was to use interdigital electrodes on one glass substrate only to produce an electric field essentially parallel to the glass substrates.Germany by Guenter Baur et al. and patented in various countries.Hitachi work out various practical details of the IPS technology to interconnect the thin-film transistor array as a matrix and to avoid undesirable stray fields in between pixels.

Hitachi also improved the viewing angle dependence further by optimizing the shape of the electrodes (Super IPS). NEC and Hitachi become early manufacturers of active-matrix addressed LCDs based on the IPS technology. This is a milestone for implementing large-screen LCDs having acceptable visual performance for flat-panel computer monitors and television screens. In 1996, Samsung developed the optical patterning technique that enables multi-domain LCD. Multi-domain and In Plane Switching subsequently remain the dominant LCD designs through 2006.South Korea and Taiwan,

In 2007 the image quality of LCD televisions surpassed the image quality of cathode-ray-tube-based (CRT) TVs.LCD TVs were projected to account 50% of the 200 million TVs to be shipped globally in 2006, according to Displaybank.Toshiba announced 2560 × 1600 pixels on a 6.1-inch (155 mm) LCD panel, suitable for use in a tablet computer,transparent and flexible, but they cannot emit light without a backlight like OLED and microLED, which are other technologies that can also be made flexible and transparent.

In 2016, Panasonic developed IPS LCDs with a contrast ratio of 1,000,000:1, rivaling OLEDs. This technology was later put into mass production as dual layer, dual panel or LMCL (Light Modulating Cell Layer) LCDs. The technology uses 2 liquid crystal layers instead of one, and may be used along with a mini-LED backlight and quantum dot sheets.

Since LCDs produce no light of their own, they require external light to produce a visible image.backlight. Active-matrix LCDs are almost always backlit.Transflective LCDs combine the features of a backlit transmissive display and a reflective display.

CCFL: The LCD panel is lit either by two cold cathode fluorescent lamps placed at opposite edges of the display or an array of parallel CCFLs behind larger displays. A diffuser (made of PMMA acrylic plastic, also known as a wave or light guide/guiding plateinverter to convert whatever DC voltage the device uses (usually 5 or 12 V) to ≈1000 V needed to light a CCFL.

EL-WLED: The LCD panel is lit by a row of white LEDs placed at one or more edges of the screen. A light diffuser (light guide plate, LGP) is then used to spread the light evenly across the whole display, similarly to edge-lit CCFL LCD backlights. The diffuser is made out of either PMMA plastic or special glass, PMMA is used in most cases because it is rugged, while special glass is used when the thickness of the LCD is of primary concern, because it doesn"t expand as much when heated or exposed to moisture, which allows LCDs to be just 5mm thick. Quantum dots may be placed on top of the diffuser as a quantum dot enhancement film (QDEF, in which case they need a layer to be protected from heat and humidity) or on the color filter of the LCD, replacing the resists that are normally used.

WLED array: The LCD panel is lit by a full array of white LEDs placed behind a diffuser behind the panel. LCDs that use this implementation will usually have the ability to dim or completely turn off the LEDs in the dark areas of the image being displayed, effectively increasing the contrast ratio of the display. The precision with which this can be done will depend on the number of dimming zones of the display. The more dimming zones, the more precise the dimming, with less obvious blooming artifacts which are visible as dark grey patches surrounded by the unlit areas of the LCD. As of 2012, this design gets most of its use from upscale, larger-screen LCD televisions.

RGB-LED array: Similar to the WLED array, except the panel is lit by a full array of RGB LEDs. While displays lit with white LEDs usually have a poorer color gamut than CCFL lit displays, panels lit with RGB LEDs have very wide color gamuts. This implementation is most popular on professional graphics editing LCDs. As of 2012, LCDs in this category usually cost more than $1000. As of 2016 the cost of this category has drastically reduced and such LCD televisions obtained same price levels as the former 28" (71 cm) CRT based categories.

Monochrome LEDs: such as red, green, yellow or blue LEDs are used in the small passive monochrome LCDs typically used in clocks, watches and small appliances.

Mini-LED: Backlighting with Mini-LEDs can support over a thousand of Full-area Local Area Dimming (FLAD) zones. This allows deeper blacks and higher contrast ratio.MicroLED.)

Today, most LCD screens are being designed with an LED backlight instead of the traditional CCFL backlight, while that backlight is dynamically controlled with the video information (dynamic backlight control). The combination with the dynamic backlight control, invented by Philips researchers Douglas Stanton, Martinus Stroomer and Adrianus de Vaan, simultaneously increases the dynamic range of the display system (also marketed as HDR, high dynamic range television or FLAD, full-area local area dimming).

The LCD backlight systems are made highly efficient by applying optical films such as prismatic structure (prism sheet) to gain the light into the desired viewer directions and reflective polarizing films that recycle the polarized light that was formerly absorbed by the first polarizer of the LCD (invented by Philips researchers Adrianus de Vaan and Paulus Schaareman),

Due to the LCD layer that generates the desired high resolution images at flashing video speeds using very low power electronics in combination with LED based backlight technologies, LCD technology has become the dominant display technology for products such as televisions, desktop monitors, notebooks, tablets, smartphones and mobile phones. Although competing OLED technology is pushed to the market, such OLED displays do not feature the HDR capabilities like LCDs in combination with 2D LED backlight technologies have, reason why the annual market of such LCD-based products is still growing faster (in volume) than OLED-based products while the efficiency of LCDs (and products like portable computers, mobile phones and televisions) may even be further improved by preventing the light to be absorbed in the colour filters of the LCD.

A standard television receiver screen, a modern LCD panel, has over six million pixels, and they are all individually powered by a wire network embedded in the screen. The fine wires, or pathways, form a grid with vertical wires across the whole screen on one side of the screen and horizontal wires across the whole screen on the other side of the screen. To this grid each pixel has a positive connection on one side and a negative connection on the other side. So the total amount of wires needed for a 1080p display is 3 x 1920 going vertically and 1080 going horizontally for a total of 6840 wires horizontally and vertically. That"s three for red, green and blue and 1920 columns of pixels for each color for a total of 5760 wires going vertically and 1080 rows of wires going horizontally. For a panel that is 28.8 inches (73 centimeters) wide, that means a wire density of 200 wires per inch along the horizontal edge.

The LCD panel is powered by LCD drivers that are carefully matched up with the edge of the LCD panel at the factory level. The drivers may be installed using several methods, the most common of which are COG (Chip-On-Glass) and TAB (Tape-automated bonding) These same principles apply also for smartphone screens that are much smaller than TV screens.anisotropic conductive film or, for lower densities, elastomeric connectors.

Monochrome and later color passive-matrix LCDs were standard in most early laptops (although a few used plasma displaysGame Boyactive-matrix became standard on all laptops. The commercially unsuccessful Macintosh Portable (released in 1989) was one of the first to use an active-matrix display (though still monochrome). Passive-matrix LCDs are still used in the 2010s for applications less demanding than laptop computers and TVs, such as inexpensive calculators. In particular, these are used on portable devices where less information content needs to be displayed, lowest power consumption (no backlight) and low cost are desired or readability in direct sunlight is needed.

A comparison between a blank passive-matrix display (top) and a blank active-matrix display (bottom). A passive-matrix display can be identified when the blank background is more grey in appearance than the crisper active-matrix display, fog appears on all edges of the screen, and while pictures appear to be fading on the screen.

Displays having a passive-matrix structure are employing Crosstalk between activated and non-activated pixels has to be handled properly by keeping the RMS voltage of non-activated pixels below the threshold voltage as discovered by Peter J. Wild in 1972,

STN LCDs have to be continuously refreshed by alternating pulsed voltages of one polarity during one frame and pulses of opposite polarity during the next frame. Individual pixels are addressed by the corresponding row and column circuits. This type of display is called response times and poor contrast are typical of passive-matrix addressed LCDs with too many pixels and driven according to the "Alt & Pleshko" drive scheme. Welzen and de Vaan also invented a non RMS drive scheme enabling to drive STN displays with video rates and enabling to show smooth moving video images on an STN display.

Bistable LCDs do not require continuous refreshing. Rewriting is only required for picture information changes. In 1984 HA van Sprang and AJSM de Vaan invented an STN type display that could be operated in a bistable mode, enabling extremely high resolution images up to 4000 lines or more using only low voltages.

High-resolution color displays, such as modern LCD computer monitors and televisions, use an active-matrix structure. A matrix of thin-film transistors (TFTs) is added to the electrodes in contact with the LC layer. Each pixel has its own dedicated transistor, allowing each column line to access one pixel. When a row line is selected, all of the column lines are connected to a row of pixels and voltages corresponding to the picture information are driven onto all of the column lines. The row line is then deactivated and the next row line is selected. All of the row lines are selected in sequence during a refresh operation. Active-matrix addressed displays look brighter and sharper than passive-matrix addressed displays of the same size, and
