dust inside lcd screen manufacturer

If you had an older 2011 iMac the cover glass is easy to get off, and has a space that is not closed off it and can get dusty. The newer 2012 onward are technically sealed! The open cell foam apple uses does allow a bit of air flow (to adjust for air pressure) but it’s not porous enough to allow dust through.

So what is going on here this looks like dust! What you are likely seeing is the degrading of the liquid crystal material, over time and the amount of static twist the liquid crystal has endured the screen can appear as dusty!

That is the first I hear about dust in an LCD. Lots of people on here get tiny bugs in there LCD and hope they crawl out. I do not have the same problem but know how much of a pain it can be. My digital camera has two pieces of dust in two separate areas inside somewhere on the lens so when I take pictures and the lighting is bright I see two blurs on the picture where the dust is. My pictures come out with the same marks in the same location. I tempted to open my camera to clean the dust but did not think I could take the telescoping lens out and put it back in so I put it back together and deal with it. Good luck with getting that hair out of there.

It"s the end of a long day,and you want nothing more than to flop down in front of your flat-screen television and watch an episode of "Modern Family" or indulge in 60 minutes of "LA Ink." Or, if the TV isn"t calling, maybe you want to do some late-night online shopping -- the dress you saw yesterday on "What Not to Wear" is calling your name. But your end-of-the-day unwinding won"t be nearly as enjoyable if you sit down and come face-to-face with a dusty, dirty LCD (liquid crystal display) screen.

Whether it"s just dust that inevitably settles on the screen or something worse (like smudgy little fingerprints), a less-than-pristine LCD screen means less-than-ideal picture quality. "Dirt or dust particles can appear like dead or stuck pixels because they block the light shining from inside of the LCD panel," says Dave Chipman, manager of product quality at Sharp, one of the leading manufacturers of LCD screens. "A coating of dust or dirt can reduce overall brightness and create a dull-looking picture."

Dust is gathering up inside the screen. It is visible when the notebook is turned off and i shine a bright light at an angle on the display. It"s actually INSIDE the display- looks like there"s a small gap between the actual display unit and the glass cover on top of it, and dust is somehow finding it"s way into this gap.

My previous notebook did not have this problem, but then again, it wasn"t a touch screen, and it did not have the glossy glass cover on top of the actual display (pressing on the display of the old laptop would cause colored sprites to show up, but on the problem notebook, this is not the case- there"s a hard glass cover on top of the screen, and i cannot press on the actual display from outside, hence no discoloration if i press. Dust is accumulating between this glass cover, and the actual display)

Short of using it in a dust-proof cleanroom like they show in those Intel TV advertisements, I don"t know what else I can do to avoid this dust buildup. And using it such a cleanroom is of course impossible.

I use it at my home, don"t take it out on dusty streets or anything, and when not in use, i always store it in the backpack that came with it. And my room is fairly clean!!

It is not worth it trying to fix a panel yourself, it is too easy to damage an LCD panel and it is not serviceable. I have an tiny spot on my LCD already but I can ignore it.

There are old tricks for removing dead pixel that may work like using a pen cover with a cloth and pressing on the black dot. But that can cause damage. I tried that on my monitor with the dust inside it does not work.

What I have determined is that there is a break-down in the sealing agent used to attach the LCD glass to the body, which causes a haze-like condition, or perhaps a dust-like situation. My D3 experienced this condition for about a year, until I discovered that there was a fogging moisture condition between the glass and the LCD. As explained in the above linked post, it was fixed by Nikon, even though it was almost 2 years past the expiration of the warranty.

If you have "dust" behind the glass there is probably a break-down of the sealing agent and there may be consequences of moisture evading the LCD area and could cause more damage. I would be very surprised that the dust condition is a result of the manufacturing procedures. I do not want to be an alarmist, but if you eventually experience a fogging like I describe in the above link, I would attend to getting it fixed.

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 screens accumulate smudges and scratches all the time. To clean these, choose a non-abrasive cloth or towel. Shut the computer off and disconnect the power cable. Wipe the LCD screen gently with a soft dry cloth. If any marks remain, moisten the cloth with LCD cleaner, and then gently stroke the cloth across the display in one direction, moving from the top of the display to the bottom. Plastic and glass cleaners containing ammonia may leave a glare-causing film, so use a computer monitor specific cleaner from a computer store. Spray the cleaner onto the cloth, and then wipe the screen with it.

Do not use any of the following chemicals or any solutions that contain them: Acetone, ethyl alcohol, toluene, ethyl acid, ammonia, or methyl chloride. If you have a different chemical or solution and are not sure whether it is suitable, do not use it. Using any of the chemicals in the previous list may cause permanent damage to the LCD screen. Some commercial window cleaners contain ammonia and are therefore unacceptable.

The television screen is what everyone sees first, but don’t forget these other key areas, not to mention the area around your unit. “It can also help to clean the furniture and carpets around the TV to prevent dust and hair from getting into it,” says Williams.

Start the remote control cleaning by removing the batteries. As with the TV screen recommendations, you’ll want to avoid spraying directly onto the surface, as this could cause the device to malfunction. Dampen a clean microfiber cloth and rub gently on the top and the underside of the remote control. For hard-to-reach gunk that’s jammed between the buttons, try a cotton swab dipped in a small amount of the cleaning solution. Make sure to let it dry thoroughly before replacing the batteries and using it again.

When figuring out how to clean a TV screen, selecting the safest cleaning solution is key, but it’s also important to know what cleaning products to avoid. Keep in mind that not only should you skip cleaning with certain products, you should also avoid spraying them in close proximity to the TV.

In terms of what to use, Samsung recommends “monitor cleaner only” (also called TV screen cleaner). Panasonic suggests “one part mild liquid dish soap diluted by 100 times the amount of water.” To make this cleaning solution, add a scant teaspoon of liquid dish soap to two cups of water, stirring well to dissolve.

Williams likes TV cleaning kits for their ease of use. “A TV kit will be your safest option for cleaning a TV,” he says. “These kits will come with everything you need to get your TV looking new, like screen-cleaning solvent and a fast-drying microfiber cloth.” You can find TV cleaning kits and cleaning products designed for flat-screen TVs at electronics stores or on Amazon.

Some people swear that only distilled water is useful as cleaning spray for their delicate electronics. Although Williams does not necessarily recommend using distilled water, if you know for a fact you have hard water in your area, you may want to try the distilled water route and see if you notice a difference. Hard water, which has high levels of calcium and magnesium, may leave a film or residue when it’s used for cleaning. Before you spray water to clean TV screens, try experimenting with tap water on a less-important screen, like an old cell phone, to assess the results.

If you can picture the hulking tube TVs (also known as CRTVs) of yore, you may also remember how delightfully easy they were to clean—a few spritzes of window cleaner and some wipes with paper towels and you were good to go—no special microfiber cloth required. But modern TVs with fancier technologies like LCD, OLED, and plasma call for gentler techniques. “Avoid using chemicals like alcohol, ammonia or acetones when cleaning your TV. These cleaners were safe to use for previous generations of TVs with glass panels, but as the hardware changes with time, the cleaning methods do too,” says Williams. Since some multi-purpose and glass cleaners are made with ammonia, skip the Windex.

Modern TVs are often smart TVs but the cleaning tips are the same as the ones for LCD, OLED and plasma TVs. The microfiber cloth is your TV screen’s best friend. “The majority of TVs you purchase today will be smart TVs, and the cleaning process is the same as TVs without smart capabilities,” Williams says.

Removing dirt from inside a MacBook Pro screen is something you can do yourself, but requires a delicate touch because it involves disassembling the screen. Whether or not you should do this yourself depends on your familiarity with computer hardware and how much dirt is behind the screen. Unless you have access to a dust-free "clean room," there is very good chance that dust will be trapped behind the glass after you have finished.

Disconnect the power adapter from the MacBook. Clean the outside of the MacBook with a dry, lint-free cloth to ensure that none of the dust or dirt on the outside will get beneath the glass when you disassemble it.

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

Before you begin cleaning a TV or LCD monitor screen, check the manufacturer"s manual for cleaning instructions. If a computer or electronic wipe is recommended, purchase a container for quick cleanups. Note that using a cleaning product or method not recommended by the manufacturer will likely void a product"s warranty. It"s also important to avoid spraying liquid on the screen when cleaning a TV. Liquids can drip into the frame, get wicked inside the screen, and cause permanent damage.

If streaks or stains remain, wet a microfiber cloth with distilled water and wring the cloth until it"s almost dry. With very little pressure, wipe the cloth across the screen in broad motions, working from the top of the screen to the bottom. If smudges persist, dampen a new microfiber cloth with 50-50 water and vinegar solution, wringing it tightly to keep it slightly damp, and wipe.

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

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

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

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

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

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

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

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

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

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

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

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

Apparently it"s in the display. Like I described earlier, when i look at the LCD monitor to view pictures that I"ve just taken, it appears like there are several tiny specks of dirt or dust. They don"t affect how much pictures look. it"s just distracting to have them there.

To catch every second of your favorite show and keep your TV in excellent condition, you"ll need to clean your television screen regularly so it remains dust-, dirt- and fingerprint-free. But using the wrong cleaning method like spraying your TV directly with harsh chemicals can cause permanent damage and negate any warranty that may still be in effect.

That’s why the Good Housekeeping Institute’s Cleaning and Media and Tech Labs have joined forces to recommend the safest, most effective methods and household products to clean your television screenand reveal a picture that’s brilliant to watch and totally streak-free.

No matter what type of television you have, our recommended cleaning method remains the same. All you"ll need to clean your TV screen is a dry microfiber cloth that’s designed to gently clean and remove smudges from eyeglasses, cell phones and camera lenses. Though there are thousands of microfiber cloths to choose from, our experts like Elite Tech Gear"s oversized option. It"s twelve inches square, so it’s easier to use on a large TV screen than a smaller cloth and helps you can zap away fingerprints quickly. And since it"s designed for delicate surfaces and electronics you can use it to clean your laptop and iPad once you"re done with your TV.

Here"s the best way to clean a flat-screen TV without ruining it or ending up pesky little streaks, along with some useful tips on how to scrub down all the accessories that go along with it:
