how to clean my lcd screen made in china

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.

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.

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

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.

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.

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

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

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

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

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

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

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

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

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.

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.

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).

It can be really frustrating to find several fingerprints on the display of your smartphone. Unfortunately, most smartphones today do not support fingerprint resistance. Thus, there is a continuous need to always wipe our smartphone screens to make them look cleaner. While many people are comfortable with a simple wipe using any clean cloth, some are not. Some users believe that they need some sort of disinfectant to make the smartphone screen clean. During the pandemic, various alcohol-containing disinfectants and cleaners have become common household items. We hold mobile phones in our hands every day and they can easily get contaminated with various pathogens. Since various alcohol-containing cleaners can not only clean oil stains but can also kill germs, wouldn’t it be appropriate to use them to wipe the smartphone screen? Well, don’t be too sure about how appropriate alcohol is for cleaning a smartphone screen.

While you may be tempted to use alcohol-based disinfectant to wipe your smartphone screen, please don’t. This is because if you do it incorrectly, it is likely to damage your phone or other electronic devices. Because using alcohol to wipe the smartphone screen is likely to cause irreversible serious damage to the screen. This is particularly true for LCD screens. So, why does alcohol have a strong erosive effect on LCD screens?

The liquid crystal screen is composed of multi-layer materials and its core is a sandwich structure with a layer of liquid crystal molecules sandwiched between two polarizers. Both the polarizer and the liquid crystal molecules themselves are very soluble in alcohol. Once corroded by alcohol, they will dissolve immediately and the screen will become mottled.

However, modern LCD screens, especially various touch screens, are not so fragile. Because we will also set a glass cover on the top layer of the screen, this cover mainly prevents scratches from damaging the screen. Furthermore, this later can naturally block various moisture and solvents from the outside from directly interacting with the structure below. But even so, wiping the screen with alcohol-based cleaners is a dangerous practice for two main reasons.

First, the surface of the glass cover is actually coated with a special organic film, such as an oleophobic film. This can reduce oil adsorption and ease fingerprints from dirtying the screen. Most of these coatings contain various organic compounds, and their resistance to alcohol is very weak. If they are wiped with alcohol from externally, the coatings are more likely to fall off. This will cause the display to become blurry. Of course, if the screen of the mobile phone is covered with film, then there is no need to worry too much about this problem.

Second, although the top layer of the LCD screen, that is, its surface is not so squeamish, its sides are still very fragile. Most of the LCD screens damaged by alcohol are actually because the alcohol penetrated into the gaps on the side of the screen. This means that as the user wipes with alcohol, the alcohol, finds its way into the sides of the display. It manoeuvres from the glass panel and drills directly into the lower structure. The surface tension of alcohol is weak and the capillary effect is strong. Once it finds its way into the side of the display, it will quickly penetrate into it. As we will all expect, the consequences are naturally very irritating.

If somehow, a small amount of alcohol enters the inside of the screen, you can immediately turn off the device to dry naturally. Alternatively, you can use a hairdryer to dry it carefully and this will not affect subsequent use.

From time to time, there is usually a need to clean the display of our smartphones. We also need to clean the screen of our tablet or computer. When we have such a need, all we have to do is spray some special LCD screen cleaner and wipe it with a soft cloth. This will make the screen clean and appear brand new. The LCD screen cleaner has a very good removal effect on fingerprints and oil films, and many wet wipes also have similar functions.

The active ingredients contained in these cleaning products are mainly surfactants. They have a good cleaning effect on oil stains and will not damage various organic coatings. If there is no similar cleaning agent, the LCD screen can also be cleaned with a damp cloth dipped in a very small amount of pure water. However, be very careful not to let water flow into the gaps around the screen.

To sum up, if it is just for cleaning, it is not safe to use alcohol. If there is a need for disinfection, then you should be cautious. Some mobile phone products will be sterilized with alcohol. It is recommended to read the instructions before disinfection. In addition, when disinfecting a mobile phone with alcohol, it is also recommended to first dip the alcohol on a soft cloth, and then gently wipe it with the soft cloth. Do not spray or pour alcohol directly on the screen, so as to prevent the alcohol from flowing everywhere and increase the risk of eroding the original screen and damaging the mobile phone.

There are multiple types of LCD screen cleaners that users can purchase off the shelf. If you feel that a simple cloth wipe is not enough, then try and purchase any of the LCD screen wipes on the market. As much as you can, try to avoid the use of alcohol or alcohol-based disinfectant to clean your smartphone. The adverse effect of this could be worth much more than the need to clean or disinfect the device.

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.

Dell recommends ensuring that the device drivers and BIOS are up to date using the SupportAssist application for optimal video performance and to help resolve common video-related issues.

NOTE: When SupportAssist does not show up in the search results, go to the SupportAssist for PCs and tablets page for information about downloading and installing SupportAssist.

To learn how to manually download and install a device driver such as Chipset, Video card (GPU), and Monitor driver (if required, most monitor drivers are delivered automatically through Windows Update) on your Dell computer, see the Dell knowledge base article How to Download and Install Dell Drivers.

We must verify whether the problem is the display screen of the laptop, video card (GPU), or video settings on the computer. A straightforward way to identify this is to connect the laptop to an external monitor or TV.

If the issue persists on the external monitor, it may be an issue with the video card (GPU) or video settings and not the laptop LCD panel. Go to verify display or video issues in Windows Safe Mode. Otherwise, go to the next step.

Performance issues may occur if there is any damage to the LCD screen. The display may stop working, work intermittently, flicker, display horizontal or vertical lines, and so on, if there is damage to the display screen.

If you notice a physical damage, contact Dell Technical Support to learn more about repair options that are available in your region. If there is no damage, go to the next step.

Dell laptops have integrated diagnostic tools that can determine if the screen abnormality is an inherent problem with the LCD screen of the Dell laptop or with the video card (GPU) and computer settings.

When you notice screen abnormalities like flickering, distortion, clarity issues, fuzzy or blurry images, horizontal or vertical lines, color fade, running a diagnostic test on the LCD helps identify if the issue is with the LCD panel.

Press and hold the D key and turn on the computer to enter the LCD built-in self-test (BIST) mode. Continue to hold the D key until you see the entire screen change colors.

If you do not detect any screen abnormalities in the integrated self-test mode, the LCD panel of the laptop is functioning properly. Go to the Update the video card (GPU) driver, monitor driver, and BIOS section.

If you notice any abnormalities in the LCD built-in self-test mode, contact Dell Technical Support to learn more about repair options that are available in your region.

Windows Safe Mode does not load any drivers, startup applications, third-party services. This will help us identify if the issue is related to the operating system, video settings, device drivers, or third-party software. To learn how to boot your computer into Safe Mode, see the Dell knowledge base article below based on the operating system that is installed on the computer:

Windows updates can support your Windows operating system in many ways. Windows updates can solve specific problems, provide security patches and protection from malicious attacks, or even add new features to the operating system.

Display settings like brightness, refresh rate, resolution, and power management may affect the performance of the LCD screen on your Dell laptop. Changing or adjusting the display settings can help resolve several types of video issues.

NOTE: Depending on the model of the Dell laptop, the shortcut keys to adjust or change the brightness may differ. See the User Guide or User Manual of your Dell laptop for model-specific information.

If you find that the Dell laptop is unresponsive to touch, touch stops working entirely, or other touch-related issues, you can try some common troubleshooting steps to help fix the touch-related issue.

System Restore is an integrated Windows tool that is designed to protect and repair the operating system. When something goes wrong with your computer, System Restore must be used before you try to restore the operating system to factory default settings.

If the diagnostic tests on the LCD panel and the video card (GPU) passed, it is most definitely an issue that is related to software that is installed on the computer. If the above troubleshooting steps did not resolve the issue, you may try to restore the computer to factory default settings as a last resort.

WARNING: Restoring or resetting the computer to factory default settings will erase all personal data on the computer. Back up all important data like documents, images, music files, spreadsheets, videos to an external hard drive or a cloud-based backup like Microsoft OneDrive.

Dell computers are built with a small amount of hard disk space that is reserved for reinstalling the operating system. This method is the easiest way to restore the computer to factory condition. The restoration process deletes all user data from the computer, so be sure to back up all your files before starting this process.
