dust inside lcd screen factory

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!

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.

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.

Regularly cleaning your LCD monitor keeps it free of dust, smudges, and germs. Wiping with a dry microfiber cloth is the safest cleaning option and is surprisingly effective at removing germs. You may need to use a dampened microfiber cloth to get rid of stubborn smudges and stuck-on debris, though. If you"re worried about germs, consider using a vinegar and water solution or a Lysol wipe on the screen. Be sure to check the device’s user manual first to make sure it’s okay to use liquids!

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.

To ensure the required standard, pre-filters are used to remove the dirt and dust that the human eye can actually see, HEPA filters capture the minuscule particles that can’t be seen.

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.

Regardless of the model you own, it is important to protect your investment.  Cleaning your television is straight forward.Flat screen TV’s have come along way. Components contributing to the television began as early as 1831.  Televisions on the market today are using semiconductors nanocrystals, self-illuminating pixels and an array of light-emitting diodes (LED) as pixels for a video display. These massive wall units deliver access to the world through content from shows, news and apps competing for our attention.  In some respects, the price for a flat screen TV has become more affordable, while the market is still there for individuals willing to pay much more for an award-winning consumer’s choice best picture.

There are some clear do’s and don’ts in caring for your flat screen. Hopefully, these tips shed some light when it’s time to clean your TV’s front and backside. Dust build-up can affect the quality of the images on your screen. By routinely cleaning your TV"s you can prolong the life of them.

Avoid using alcohol or other consumer cleaning product with harsh chemicals. Glass cleaners contain both alcohol and ammonia. Many televisions have anti-reflective coatings. Alcohol can cause clouding and permanently damage the screen

Too much moisture could cause an electrostatic charge and cause it to burn out. If water enters the control unit it may need to be replaced.  In many TV’s, the connections to the panel are at the bottom of the TV and if water seeps inside the unit it may short out some of the contacts to the panel. Consult and expert but in those cases the panel may need to be replaced, which may not be cost effective.

Dust can become trapped in the fibers and create scratches on your screen.  A higher GSM count microfiber cloth is plush and better for trapping dust. However, the dust remains inside the fibers and may cause tiny scratches on the screen.  These are great cloths but not ideal for cleaning a flat screen.

Most cities in the united states suffer from hard water which contain minerals such as calcium and magnesium which tend to leave a visible residue on your screen.

A flat weave cloth does not trap dust into the fibers and is what is used to clean dust and fingerprints off eyeglasses and fine glassware without scratching the lenses.

Gently wipe the surface using a clean, dry or barely damp split fiber microfiber cloth. These cloths have an electromagnetic charge which attract dust to the cloth. The split fibers trap the dust there. Be careful to not rub or press too hard on the screen.

Moisten the cloth so it is barely damp to wipe away harder to remove dirt.  The split fiber microfiber cloths are much more effective in reaching deep into crevices to trap dust bunnies that may have begun to settle along the air vent slots.

It is important to use the best tool for cleaning the flat screen.  A flat weave microfiber cloth is the best option for cleaning a flat screen just as you would to polish wine glasses and optical lenses.

If your cloth is larger, fold it in half and then half again.  This Allows you to clean with 8 clean sides of the cloth.  You should never have to use a dirty part of the cloth more than once if you purposely clean 1/4 of the screen at a time.

Your television is probably one of the last things you think about adding to your "to clean" list, but the difference between a smudgy screen and a crisp picture isn"t one to shrug at. Every day, our TVs accumulate dust and fingerprints, and the buildup occurs so slowly that it"s hard to notice. That is, until you take a quick 10 minutes to clean your TV and revel in a far more satisfying cinematic experience.

We asked a couple cleaning pros for the full rundown on how to clean TV screens of all types, including flat plasma and LCD screens, along with some common mistakes people make when cleaning their TV screens so you know exactly what to avoid.

To prevent buildup from accumulating on your TV screen, aim for a once-weekly TV cleaning. "It"s important to clean your TV screen not only to prolong its lifespan, but also to provide the clearest picture possible—smudges, dust, and fingerprints be gone," says Kathy Cohoon, a cleaning professional with Two Maids & a Mop. "It can make a big difference in the aesthetic of your TV and the picture on screen."

Power down. Before breaking out any dust cloths or cleaners, make sure your TV is off. If you want to take an additional precaution, Cohoon says you can also unplug the TV, but it"s typically not necessary for modern TVs.

Dust the screen. Dry dusting your TV is a crucial step in the cleaning process. "Removing dry debris will ensure that you don"t accidentally create scratches by scrubbing a rough piece of dirt or buildup into the screen," Cohoon says. She recommends using a microfiber or soft cloth to gently dust the entire screen. If needed, flip the cloth over (or get a second cloth) in order to completely remove all dust, pet hair, and other loose debris. You can use a microfiber cloth to wipe down the speakers and cords as well.

Use screen-safe cleaner.Spray a small amount of screen-friendly cleaning product onto a soft cloth—never directly onto the screen itself—and wipe the TV down in a methodical, back-and-forth motion. Check that the cleanser is safe for the specific type of screen you are cleaning. Repeat as necessary to remove oily areas or fingerprint smudges. Also, don"t forget to gently wipe down the top and base of the TV.

Clean smudges on the screen."For tougher spots, make sure not to apply too much pressure, especially on more delicate screens," advises Leanne Stapf, the chief operating officer for The Cleaning Authority. "If microfiber cloth spot-cleaning doesn"t work, I recommend adding a bit of warm water to the cloth and then cleaning the spot with the dampened cloth."

Dust.Use a microfiber cloth to gently wipe away loose dust, dirt, or any other debris. You may need to turn the cloth over or get a second one to adequately remove everything.

Wipe down the screen."Since these screens are a bit sturdier, you can mix equal parts rubbing alcohol and lukewarm water to create a cleaning solution," Cohoon says. "Using a small amount of solution on a soft cloth, wipe the entire screen, base, and top." Spot-clean any stubborn areas with caked-on messes or heavy fingerprints. You can also remove fingerprints by rubbing with a microfiber cloth in a circular motion.

​​To clean and sanitize a remote, Stapf says to simply use a disinfecting wipe to remove bacteria, germs, fingerprints, and any other residue. Make sure the cleaning wipe is damp but not soaking wet to avoid getting liquid inside the remote control. Spend some time cleaning between the buttons since gunk can easily accumulate here.

Forgetting to Dust First: "A big misstep when cleaning a TV is forgetting to dust the screen before using a cleaning agent," says Cohoon. This can lead to tiny scratches that slowly degrade picture quality.

Scrubbing Too Hard:Modern TV screens are delicate and require a gentle touch. Wiping too vigorously or using a rough cloth can damage the screen quickly.

Spraying Solution Directly Onto the TV:All wet cleaners should be sprayed onto a cloth and then wiped over the TV. Spraying directly onto the screen can create spots that are hard to remove. It also puts you at risk of damaging the speakers.

Using Non-Approved Cleaners: Using store-bought glass cleaners on OLED or LCD TV screens is a big no-no. Stapf says, "These products contain harsh ingredients like alcohol and ammonia, which can damage the panels of the screen."

Everyone is spending more time staring at their laptop, tablet, or computer screens these days—which means more chances for finger smudges, accidental coffee drips, or even a wayward sneeze. All things considered, we could all be cleaning our laptop screens more frequently.

Fortunately, cleaning a laptop screen takes only a few minutes and a few basic supplies. The key to successful screen cleaning is that less is more. It"s important to use the least amount of cleaning products and the gentlest pressure possible to prevent damage to the screen.

There are two basic types of laptop screens: glass-covered LCD (liquid crystal display) screens and nonglass-covered LCD screens. Glass-covered screens, featured on many Apple products, are more durable and can withstand more moisture and stronger cleaning products like disinfecting wipes when cleaning. LCD screens that are not protected by glass can be permanently damaged by many cleaning products.

Before you attempt to clean your laptop screen or any electronic device, take the time to read the manufacturer"s guidelines on cleaning and maintenance. If you"ve lost or tossed the owner"s manual, you can find them online.

How frequently you clean your laptop and the screen will depend on how often you use it. If you use it daily, cleaning the laptop screen, keyboard, and external parts, should be done at least weekly. Laptops that travel around with you to places outside the home should be cleaned more often. Plan a deep clean every three to six months on the entire laptop.
