Chemicals leaking from millions of computer screens in homes, offices and schools could damage human health, according to research by Chinese scientists.

Chemistry professor Su Guanyong and colleagues at Nanjing University of Science and Technology in eastern Jiangsu province studied more than 360 types of chemicals used in computer and mobile phone screens and found that 87 of them could be a danger if they got into the environment.

Some chemicals in liquid crystal displays (LCDs) could alter genes, they said. Animal cells mutated unexpectedly if exposed, and preliminary results of their ongoing study published in Proceedings of the National Academy of Sciences on Monday showed that one of the most polluted places was the home.

Studies found that excessive radiation from screens could speed up the ageing of skin and blue light from diodes could harm the retina of the eye. "But nobody has looked beyond the brightness to unveil the dark secrets behind," Su said.

Over the years, screen panel manufacturers have pushed LCD technology to higher resolutions and faster refreshing rates, but the chemical composition of the liquid crystal that fills their screens has hardly changed.

Su and colleagues produced a list of chemicals used by manufacturers and found that 87 " about a quarter of the substances tested " might be "persisting organic pollutants" that were not only harmful to health, but their composition meant they would take years or sometimes decades to decompose. The exact effect of these chemicals was unknown.

They exposed embryonic chicken cells to liquid crystal taken from the screens and compared them to cells grown in normal conditions. They found genetic changes that suggested the exposed cells had mutated.

"Our laboratory has tested a large number of toxic substances. This [effect] is similar to the exposure of other known persistent organic pollutants," Su said.

The Nanjing team was baffled by the amount of liquid crystal in the air. They knew screens were made in dust-free factories and sealed, but their surveys of hotels, school buildings, canteens, dormitories, electronic product repair centres, homes and laboratories revealed surprising results.

The lowest levels were found in a canteen, a dormitory and classrooms. Su said they were not sure where the drifting liquid crystals came from. Some screens might have been cracked or broken, he said. If a screen was left on for a long time, heat and radiation might cause liquid crystal to evaporate.

There was no solution to the problem at this stage, the researchers said. To push the government for more strict regulations meant that the scientific community had to come up with more evidence and a better understanding of the problem.

"Electric device recycling plants could be a major source of emissions, with broken screens dumped everywhere and little protection. This practice must stop," he said.

JIANGSU (China) — Chemicals leaking from millions of computer screens in homes, offices and schools could damage human health, according to research by Chinese scientists.

Chemistry professor Su Guanyong and colleagues at Nanjing University of Science and Technology in eastern Jiangsu province studied more than 360 types of chemicals used in computer and mobile phone screens and found that 87 of them could be a danger if they got into the environment.

Some chemicals in liquid crystal displays (LCDs) could alter genes, they said. Animal cells mutated unexpectedly if exposed, and preliminary results of their ongoing study published in Proceedings of the National Academy of Sciences on Monday (Dec 9) showed that one of the most polluted places was the home.

Dr Su, professor at the school of environmental and biological engineering, said he had been worried about the effect of exposure to computer screens on human health for a long time.

Studies found that excessive radiation from screens could speed up the ageing of skin and blue light from diodes could harm the retina of the eye. “But nobody has looked beyond the brightness to unveil the dark secrets behind,” Dr Su said.

Over the years, screen panel manufacturers have pushed LCD technology to higher resolutions and faster refreshing rates, but the chemical composition of the liquid crystal that fills their screens has hardly changed.

Dr Su and colleagues produced a list of chemicals used by manufacturers and found that 87 – about a quarter of the substances tested – might be “persisting organic pollutants” that were not only harmful to health, but their composition meant they would take years or sometimes decades to decompose.

Dr Su’s team went to a phone repair shop and bought used screens found in six mobile phone brands in China and abroad. “We don’t want to name them because this is not a problem of specific manufacturers. It is the whole industry,” he said.

They exposed embryonic chicken cells to liquid crystal taken from the screens and compared them to cells grown in normal conditions. They found genetic changes that suggested the exposed cells had mutated.

“Our laboratory has tested a large number of toxic substances. This [effect] is similar to the exposure of other known persistent organic pollutants,” Dr Su said.

The Nanjing team was baffled by the amount of liquid crystal in the air. They knew screens were made in dust-free factories and sealed, but their surveys of hotels, school buildings, canteens, dormitories, electronic product repair centres, homes and laboratories revealed surprising results.

Liquid crystal was not only present in the air in all of these places, but the second-highest concentration was found in flats, while a laboratory that housed a large number screens topped the list.

The lowest levels were found in a canteen, a dormitory and classrooms. Dr Su said they were not sure where the drifting liquid crystals came from. Some screens might have been cracked or broken, he said. If a screen was left on for a long time, heat and radiation might cause liquid crystal to evaporate.

There was no solution to the problem at this stage, the researchers said. To push the government for more strict regulations meant that the scientific community had to come up with more evidence and a better understanding of the problem.

“Electric device recycling plants could be a major source of emissions, with broken screens dumped everywhere and little protection. This practice must stop,” he said. SOUTH CHINA MORNING POST

Scientists have discovered that LCD screens leak chemicals into just about every environment where they are found, according to a new study, and these particles have the potential to be toxic over time.As described in a study published last week in Proceedings of the National Academy of Sciences, researchers collected dust samples from seven buildings in China: a cafeteria, student dorm, classroom, hotel, home, lab, and an electronics repair shop. Nearly half of the 53 samples tested positive for liquid crystal particles—which are supposed to stay sealed in the screen after manufacturing—even in places where there were no LCD devices at the time of collection.AdvertisementThe international research team analyzed 362 chemicals used in LCD screens and found that nearly 100 have the potential to be toxic. These particles don’t break down quickly and have "high mobility" in the environment. When inhaled or ingested, according to the study, these particles can build up in the body over time with toxic effects, potentially causing digestive problems and other health issues.“These chemicals are semi-liquid and can get into the environment at any time during manufacturing and recycling, and they are vaporized during burning,” said University of Saskatchewan environmental toxicologist and lead author John Giesy in a press release. “Now we also know that these chemicals are being released by products just by using them.”According to the study, these chemicals are "simply filled" into the space between polarizers (light filters) during manufacturing and are not chemically bonded to any base material. This means that "they can be released during production; through wastewater; or during active use, disposal, or recycling."To be clear, the researchers didn"t observe any adverse health effects from the accumulation of liquid crystals in the human body; they only found that these crystals do in fact leak from devices, and that they have the potential to be toxic.

“We don’t know yet whether this a problem, but we do know that people are being exposed, and these chemicals have the potential to cause adverse effects,” said Giesy.AdvertisementLab testing showed that the hazardous substances found in phones were similar to flame retardants, which have proven to be toxic to living creatures, creating problems with animals’ digestive systems and hindering their ability to absorb nutrients. They also disrupted their gallbladders and thyroids.The team says the next step is to understand the effect of these chemicals on humans, animals, and the environment. “Since there are more and more of these devices being made, there’s a higher chance of them getting into the environment,” said Giesy.Right now, there are no standards for measuring them and no regulations limiting exposure to them. “We are at ground zero,” he said.Giesy’s previous work was the first to shed a spotlight on toxic perfluorinated and polyfluorinated chemicals (PFCs). PFCs used to be in all kinds of oil and water-resistant products such as raincoats and non-stick pans. His findings led to a global ban of PFCs.

Gone are the days when people used to buy CRT based computer monitors. Well! With time, the picture has certainly changed. CRT screens have become obsolete now and these have been perfectly replaced by LCD screens. With an LCD screen, it is not only fun to work in but also the interface looks more colorful and stunning. LCD screens are expensive for sure; and, thus it becomes hard to accept when such screens get damaged. Whenever a computer screen gets damaged, users often overlook the idea of repairing the screen immediately. But, mostly they do not realize that it can be hazardous.

Exactly! A broken LCD screen can be pretty harmful for the user and for the surrounding environment. And, this is high time to realize that. So, here we have tried to highlight the risks involved with a cracked LCD computer screen. Without further ado, let’s talk about it.

The computer LCD screen generally uses Mercury in order to produce the visible light for the viewing purpose. When a crack develops on the screen, then Mercury generally vaporizes. If the Mercury level drops, then it can become hazardous for the human body; allergic reactions, severe rashes on the screen, and birth defects are some of the often-reported disorders that can be triggered due to this low level of Mercury. And thus, we always suggest this thing to everyone that the moment you find a crack on your LCD screen, please visit a reputed repairing store. At iTech Xpress, our clients say that we offer the best LCD screen repair service inCovina.

LCD screens usually take the help of liquid crystals for the formation of a particular picture. And, it is quite an uncommon phenomenon when the crystals leak from the system. Well! When crystals leak out, they usually do not look like liquid anymore. It is not quite a well-known fact that how the human skin reacts with these crystals; this phenomenon is yet to study. So, it is always mandatory to contact a repairing service center the moment users find a crack to develop on the screen.

Whenever a crack develops on the computer LCD monitor, there are a number of health hazards that every user needs to be aware of. It is mandatory to use gloves and masks while handling these materials; one cannot simply overlook the hazardous components and the unknown side effects associated with the materials. At iTech Xpress, we try to repair every kind of broken LCD screens. Unlike many repairing centers, we simply do not ask users to buy a new monitor or something like that. We strive for excellence and that makes us one of the best repairing centers in Covina & Glendora. We are ready to serve you, are you?

The international research team, led by USask environmental toxicologist John Giesy, is sounding the alarm about liquid crystal monomers--the chemical building blocks of everything from flat screen TVs to solar panels--and the potential threat they pose to humans and the environment.

"These chemicals are semi-liquid and can get into the environment at any time during manufacturing and recycling, and they are vaporized during burning. Now we also know that these chemicals are being released by-products just by using them,"said Giesy, Canada Research Chair in Environmental Toxicology at USask.

"We don"t know yet whether this a problem, but we do know that people are being exposed, and these chemicals have the potential to cause adverse effects,"said Giesy.

In a first-of-its-kind paper published, Giesy"s research team assembled and analyzed a comprehensive list of 362 commonly used liquid crystal monomers gathered from 10 different industries and examined each chemical for its potential toxicity.

The researchers found the specific monomers isolated from the smartphones were potentially hazardous to animals and the environment. In lab testing, the chemicals were found to have properties known to inhibit animals" ability to digest nutrients and to disrupt the proper functioning of the gallbladder and thyroid--similar to dioxins and flame retardants which are known to cause toxic effects in humans and wildlife.

To understand how common these monomers are in the environment, researchers tested dust gathered from seven different buildings in China--a canteen, student dormitory, teaching building, hotel, personal residence, lab, and electronics repair facility. Nearly half of the 53 samples tested positive for the liquid crystal monomers.

"Ours is the first paper to list all of the liquid crystal monomers in use and assess their potential to be released and cause toxic effects,"said Giesy. "We looked at over 300 different chemicals and found that nearly 100 have significant potential to cause toxicity."

Ninety percent of the monomers tested had concerning chemical properties. They either accumulate in organisms, resist degradation in the environment, or are easily transported long distances in the atmosphere. Nearly one-quarter of the chemicals tested had all three troubling characteristics.

Researchers Huijun Su, Shaobo Shi, Ming Zhu, and Guanyong Su of China"s Nanjing University of Science and Technology, along with Doug Crump and Robert Letcher of Environment and Climate Change Canada, worked with Giesy to conduct the research. Guanyong Su, who leads the research effort in China, was a former student with Giesy at USask and then a post-doctoral fellow with Environment Canada.

LCD panels are almost exclusively produced in three Asian countries: China, Japan, and South Korea. It"s estimated that 198 million square metres of liquid crystal display were produced last year--enough to cover the entire Caribbean island of Aruba.

For many years, huge amounts of globally produced e-waste--including LCD displays--have been dismantled, disposed of, and introduced into the environment.

"Right now, there are no measurements of these monomers in surface waters. Our next steps are to understand the fate and effect of these chemicals in the environment,"said Giesy.

In his previous work, Giesy was also the first researcher to identify that toxic perfluorinated and polyfluorinated chemicals were widespread in contaminating the environment. His research ultimately resulted in the entire class of chemicals being banned globally.

Liquid Crystal monomers don’t have protein. Their chemical structures look like below. The effect of these chemicals shows in MSDS (Material Safety Data Sheet).

-Any artificial chemicals have potential hazard to human health. If you read the notes of your prescription drug, the statement is likely more alarming than above.

-If you crack LCD screens and find the liquid crystal leakage, don’t panic. Just remember that the liquid crystal materials might not be more toxic than your detergents for stove or washroom. Just wash your hands with soup throughout. Never try to play with it or even worse to taste it. The liquid of the cracked computer screen will not evaporate, no emissions worries.

-Any electronics has environment impact and can’t be used landfills. If you want to get rid of old LCD monitors or LCD TVs, give them to electronic collection stations. Let’s the professionals to handle them. They will extract some precious metals/parts and make them into something useful or at least not hazard. FYI, liquid crystal materials are retrievable.

Since there are some differences in quality between the China-made iPhone screens and original iPhone screens, so you need to be careful when handling the new iPhone screen replacement, according to our test, the top corner of the screen is one of the key parts that should be gently treated. Don’t push these 2 corners with force when reassemble the phone.

After installing front camera and ear speaker, you’ll need to hold them with the metal bracket, there is another point you need to be carefully dealing with, please note that all the screws have unique positions, don’t mix them with wrong position, and what needs to be paid more attention to is the rightmost one with a red circle showed below, do not twist this screw too tight, or which can somehow cause the screen cracked after reassembling the screen.

After connecting the screen connectors, then you may need to test the screen functionality before totally installed. You’d better make the angle between the screen and body is less than 45 degree during the screen test. With screen test finished, then the last step, make sure the screen replacement is properly aligned with the housing edge.

One risky thing you wouldn’t want to do is using your phone while the screen is cracked or broken. You are putting your phone internal components and yourself at risk when you continue using your device with the cracked screen. Today let’s take a look at some risks of using a broken or cracked phone screen.

Once your phone screen is broken or cracked, the touch screen will start to misbehave and your phone won’t be responding to touch quickly. The response time will be delayed now, due to the cracked or broken screen.

A cracked or broken screen has lost some part of its glass protection on the screen, thereby giving way to liquid substance, dust and dirt to reach the internal components of the phone that was formerly protected by the screen. Once liquid substance gets to the internal component of the phone, you are at risk of damaging the phone completely, because those liquid substance may destroy the internal components and also the motherboard.

Smartphones screens are made up of glass, so you are putting your fingers at risk when using the phone. You are at the risk of cutting your fingers when you swipe on the broken screen. That wouldn’t be something you would like to experience.

Once your smartphone screen is broken, the quality of the display is compromised and you won’t be able to read your messages. Due to some part of the screen being completely destroyed from the impact of the fall ,you may end up straining your eyes in order to make sense of what’s been displayed on the screen. This is very bad for your eyesight and you will also waste some time trying to figure out what is being displayed on the screen.

Smartphones are already emitting some amount of radiation but not much to be harmful to a human. But when your phone screen gets cracked, it allows more escape way for radiation from the phone, which is harmful to the human body system.

It will become more difficult to use a phone with a cracked screen, when you are unable to execute some certain commands on the phone because the phone won’t be responding to your touch.

We call this ghost touching because your phone will start operating itself as if you were the one touching the screen. This happens due to the damage sustained from the cracked screen.

It is advisable that you get your broken or cracked phone screen fixed as soon as possible. Carlcare service center offer professional phone screen repair services and you are sure to get original replacement parts if your Infinix, TECNO or itel phone is broken as we are the official after-sales service center for these brands.

In the case where you are a bit financially down and you cannot afford to get screen replacement at the moment, you can purchase a tempered glass screen protector for your device.

You can fix the tempered glass screen protector by yourself or from the sales person at the store when you purchased it. However, this is not a permanent solution as a broken screen doesn’t get any better as times goes by and it can start to malfunction at any point in time.

“Original” screens are those containing LCDs manufactured for Apple. “Copy” screens are compatible replacements entirely designed and manufactured by third-party companies not associated with Apple.

LCD display panel can have poorer resolution (i.e. looks “coarser”), worse brightness, contrast and vibrancy and reduced refresh rate amongst other problems.

Changes in specification from original can result in battery and performance issues. Certain badly-engineered screens could even damage the backlight circuitry.

Customers who bring their iPhones to us for a screen repair are offered two choices of replacement- an original or a “copy” screen. The most common response is “Is there a difference- and which one would you recommend?”

Originals are those screens containing LCDs that were manufactured for Apple. So-called “copy” screens are compatible replacements, but designed and manufactured entirely independently by third-party companies, typically in China.

Our answer is simple- the original screen is the one we’d go for ourselves, every time. Some people think we make more money on them, but this isn’t the case. We recommend originals because they’re far higher quality and the price difference is fairly small.

We’d rather only fit original screens. The only reason we don’t is that many people will shop around and choose purely on price. As such, we need to offer the cheaper copy screens to remain competitive and avoid losing these customers. In some cases, they didn’t even know there was a difference in the first place- especially since it’s not in some shops’ interest to draw people’s attention to the issue!

This may well be the worst copy screen we’ve ever come across. As a result, the unfortunate customer has ended up paying twice to have their screen replaced- we’re sure that had they been properly informed, they would have chosen an original in the first place.

While the difference in price between copies and originals can vary across devices, it’s generally around £10 – £14 extra to have an original screen fitted. This really isn’t a lot considering the improved quality and reliability.

We compare our prices to our competitors- and we know that we come out of it favourably. While we have to offer copy screens to remain competitive, we always advise customers to go for the original.

When you’ve spent- directly or indirectly- several hundred pounds for an iPhone with a Retina display, it doesn’t make sense to replace it with a lower-quality screen that can make a £400 phone look like a £40 one! Not only that, but you’re likely to have fewer issues, and a longer-lasting screen.

There’s nothing stopping any random person without training or experience opening up a smartphone repair shop. As a result, the industry is full of companies with little skill or experience who are only interested in getting hold of your money and installing the cheapest parts they can find.

Many- if not most- don’t even acknowledge the existence of copy screens, let alone explain the difference to the customer. Hardly in their interest to do so if they only fit cheap, low-quality copies. Some of them can hardly be blamed- they know so little, they’re not even clear on the differences between OEM, non-OEM and copy displays themselves! Others can be more deliberately misleading… and some outright lie.

Generally, these shops are looking for the cheapest price on replacement screens.. When offered a copy at a half or a third of a price of the original, they’re going to go for that. That might be fine if they offered the customer a cheaper price- what we disagree with is selling “supermarket beans” (i.e. the copy screens) at “Heinz beans” prices!

Heading towards the “blatantly fraudulent”, we’re aware of companies that shamelessly fit copy screens while claiming them to be original. Worse, they’ll take your broken original screen and sell that to a recycler for more than they paid for your copy!

Obtained or manufactured “off the clock” via the same production line that produced them for Apple- in some cases, from the stockpile of parts that didn’t meet Apple’s standards, or

Apple tightened up their supply chain around 2015, which reduced the number of screens available for repairs and increased their price dramatically. A lot of companies went bankrupt, and Chinese manufacturers responded by making their own “copy” screens from scratch. At first, these weren’t much cheaper than the Apple ones, but the price soon fell.

We should be clear that- despite the name- “copy” screens aren’t direct copies of the Apple originals. Rather, they’re compatible replacements that have been designed from scratch and- as a result- vary in some respects that have an effect on usability and quality.

One of the most important differences between an original and a “copy” screen is how the digitizer (touch sensor) is designed. Apple has it manufactured as part of the LCD itself, whereas the copies have it on the glass.

Although there are only a small number of manufacturers of the bare LCDs themselves, these are then bought by countless other companies who add the remaining components needed to turn these into a complete working screen. As a result, you could easily end up with an LCD from the best “copy” manufacturer, but the digitizer/touch (as part of the separately-manufactured glass) from the worst.

There are countless digitizers out there, and you can only take the supplier’s word that the quality is good. Many ship good ones at first, then switch to cheaper parts to make more profit. This is particularly bad with the iPhone 6S and 6S+, since Apple moved the chips responsible for touch processing onto the LCD itself. As a result, you’re not just getting a copy screen- you’re getting copy chips too.

The performance specification (power drain, etc.) of most copy screens isn’t identical to the originals. As a result, they can drain the battery more quickly and mislead the operating system which was optimised for the original screen design.

It’s even possible that this mismatch could damage your backlight. We do a lot of subcontracted repairs for less-experienced shops, and get backlight repairs in almost every day. We’ve had cases where we fixed the circuit, fitted the new copy screen to test it, and had it break the circuit again!

Copy screens can disrupt the touch ID fingerprint reader. With the 6S, 6S+, 7 and 7+, the home button- part of the 3D touch- is part of the screen assembly. Frequently the home button flexes on aftermarket designs don’t work properly and stop the touch ID working- annoying if you use it to unlock the phone or log in to your bank.

We’ve seen many lift away from the frame that holds them in place. This usually results in the flex cable getting torn, and the screen needing replacing. You don’t even need to have dropped the phone- this often happens through general everyday wear and tear.

That brings us to another major issue with the copies. When you drop an Apple original, the glass often breaks, but if the LCD itself is intact, you can continue to use it until it’s fixed. With the copies, the touch/digitizer is on the glass and stops working when that’s broken. Even worse, the LCD itself is more likely to break due to the thinner and more fragile glass.

We’re not convinced this will happen, since Apple recently changed their repair policy to accept iPhones with third-party screens. However, it is possible that copy screens could be stopped from working via an iOS update, since those make a number of security checks.

Mandy, ETS is obviously a company that you are connected to and this could easily be taken for spam. I think we can make an exception at this time since you are asking a good market research question that may be useful to many.

Having checked out your video, I personally will not use the aftermarket screen as a replacement for my X. It just doesn"t have what I expect for a $1000 USD phone. I recognize that $300 USD for a replacement is hefty but the aftermarket screen does not appear to have the quality that I would expect for my phone.

It would be literally tempting for you to use your MacBook as usual when you have got a cracked screen on it as you don"t want to spend extra cash on it and get it fixed in the middle of the work day. The damage may appear minor at first and this would be the perfect time for you to procrastinate. There are a number of damages that occur if you ignore a cracked MacBook screen and some of them might look obvious to you but others would surprise you. Before it cause more damage to your gadget, it is important that you seek help from Professional MacBook repair Mumbai technicians. Here in this blog, we are going to talk about the risks of using the MacBook with a cracked screen.

· Issue can get worse: The crack that has appeared at the corner of your MacBook screen may not seem like a big deal for you but it can worsen the issue. This is because the daily stress that your MacBook course through to your bag can make the small crack start to spread. With each and every small amount of pressure you put on your screen, can cause the crack to worsen day by day. The things can deteriorate rapidly in your MacBook.

· Causes eye strain and complicates the navigation: Not only a cracked MacBook screen can put a strain on your eyes but will also decipher what lies underneath that cracked screen. It can make difficult for you to figure out what"s on the screen and may even lead you to click on something else than what you"ve thought it to be. It can further lead to blunders that can cause losses in your professional or personal life.

· Can cause your display to malfunction:Even if the screen of your MacBook may continue to work as usual but a crack can cause long term display issue to malfunction. It can create a pressure on the display. It even creates exposure to the elements such as dust and moisture that can make the situation from bad to worse.

· Leave the screen exposed to the elements: The screen of MacBook works more than just a display - it is constructed to protect the inside of your MacBook from moisture, dust, dirt and foreign elements that the device encounters on a daily basis. The professional MacBook repair Mumbai cleared the fact that the moisture that air contains can cause the cracked MacBook screen to have negative effects on the overall health of the MacBook it can even cause damage to the hardware that would not be repairable.

Alibaba.com offers 92 buying broken lcd products. such as 6.7. You can also choose from 100% tested. As well as from samsung, apple iphone, and huawei. And whether buying broken lcd is 1 year, 18 months, or 2 years.

Cracked or broken mobile device screens can be costly to fix, but a few inexpensive do-it-yourself strategies can eliminate a repair shop visit and salvage your tablet or phone.

Third-party repair shops typically replace glass on a tablet for about US$100-$200, depending on the model. Replacing the tablet’s touchscreen can cost $50-$75 extra.

Replacing the cracked glass with a functioning touchscreen is much cheaper. You usually can find suppliers online for $6 to $20 for a phone. A tablet replacement digitizer can cost about $50 or more if you perform the work.

It is relatively easy and cheap to replace the glass on a phone once you get the hang of it. Tablets are a bit more involved because of the larger size and added components.

Tools might require an additional monetary outlay if you do not have a well-functioning workbench. Depending on the device involved, you need a phone opener pry tool, little tweezers to deal with small cables inside, a Torx screwdriver, flat-head screwdriver and a precision screwdriver kit.

Add to that list either a variable hair dryer or a heat gun to soften glued phone parts. Also add scissors, double-sided adhesive tape, canned air and work gloves.

It is first things first when it comes to fixing cracks on a smartphone’s screen. Often, the actual screen is not cracked at all. You may have installed a glass screen protector when you purchased the phone.

The film covers can become cloudy or scratched. They usually help absorb shock from items dropping on the tablet to lessen risk of cracking the touchscreen glass under it.

When the culprit really is a damaged screen, choosing one of the next three approaches can help you solve the problem. You might be able to repair the damage rather than replace it.

For instance, is the screen clouded or otherwise damaged from your mistaken use of harsh cleaning fluids or coarse paper towels to clean the screen? If so, there is a fix for that.

Is the screen merely cracked or full-out broken — as in massive spider cracks from being smashed? You can cure a cracked screen on a phone or tablet more easily with Sugru, a commercial product. A fully cracked screen on either type of device is a solid candidate for a screen replacement.

If your phone or tablet screen shows signs of cleaning abuse or wear from heavy handling, return its condition to nearly new with an oleophobic coating kit. This is an oil-repellent coating that protects the screen, along with adding smoothness and reducing fingerprints.

The coating, a thin layer of fluoropolymer-based solids, is similar to Teflon and is bonded to the glass. You can buy the coating kit from a variety of electronic supply stores and online outlets.

Prepare a wiping finger. The oleophobic coating’s liquid solvent evaporates very quickly when applied, so once you start, work quickly. Wrap one finger with plastic wrap or a sandwich bag. Use this finger to rub the coating liquid onto the screen.

Apply 10-15 drops of the coating to the screen’s surface. If the phone or tablet screen has a large surface, apply 10 drops to a portion of the screen, working on one portion at a time.

Wipe the screen dry with a clean microfiber cloth. Then give the coating time to dry. Do not touch the screen for 8-12 hours to allow the coating to bond to the surface.

If your only complaint involves tiny scratches and cracks on a smartphone screen or a tablet glass, there are remedies that work with varying degrees of reliability. You can use a household eraser pad or an actual pencil eraser.

Pencil erasers also work reasonably well in making scratches disappear. Simply rub the scratch left and right with the eraser for about 60 seconds. Then rub it up and down for 60 seconds.

Does using toothpaste to fill in the cracks really work? I put that fix in the category of more “mythful” thinking, but I know people who swear that this method is a cheap fix that works.

Sugru is a moldable glue kit for repairing rather than replacing cracked screens. Actually, the product was not created with phone and tablet repairs in mind. Its intended purpose is more in the line of general repairs where bonding surfaces together and filling surfaces are needed.

Depending on how badly the screen is damaged, it can be a good solution for cracks that spread from the phone or tablet screen’s edges. However, for massive cracks that spread over the entire screen — as spider cracks tend to do over time — it will be a short-term fix at best.

If your phone or tablet screen has suffered more serious damage, full scale surgery is the only option other than getting a new device. Repairing the device’s LCD screen is a complicated procedure due to the compact internal design.

The repair process involves completely dismantling the phone or tablet’s outer casing. It is particularly easy if the replacement screen comes with a top frame.

Otherwise, you may have to seal the layers to avoid loss of structural strength and moisture/dust protection. You can use either sealing pads for the size of the particular device at hand or double-sided sticky tape. A simpler solution for phone screen replacement is to use B-7000/T-7000 glue.

Before you roll up your sleeves to get started, take one huge safety step. Buy and use a static wristband and a static guard mat. This will ensure against accidentally frying any electronic components while disassembling and reassembling the devices. Disconnecting the battery is not always a guarantee that static discharge will not happen.

The first step is to tear down the device so you can assess the extent of the damage and determine what screen parts to order. Locate the model number for the LCD screen. Use this number in an Internet search to find a replacement screen.

The part or model number usually is printed on a label adhered to the sensor cable attached to the screen. You can access this cable after you separate the screen from the rest of the unit. Carefully disconnect the cable connector from the backside of the screen along the edge.

Step 2: Loosen any stuck-on cabling that is now exposed, like the camera cable. Then remove cables if the clasps are exposed. These cables simply slide out of any exposed sockets after clasps are released. The tape-style cables are often held onto the frame and parts by adhesive, so tug gently to release.

Step 3: Unscrew the Phillips or Torx screws that hold the motherboard-containing back frame to the LCD-containing chassis and place the screws in a bowl for safe-keeping. Then separate the back frame from the chassis by gently and carefully pulling the two apart.

Step 4: Remove any further cable assemblies that have become exposed by the separation of parts. Maintain visual cues as to which cable to reattach where. For example, place them on the work surface face-up in the order of removal. Or take photos with a digital camera or smartphone.

Step 5: Remove the LCD-containing chassis from the front frame or bezel and glass assembly by unscrewing a second batch of screws. Store the second set of screws in a second bowl. Remove any further parts such as the camera.

Step 6: Don’t touch the LCD face. Separate the existing, damaged glass from the bezel or front frame by waving the heat gun over the adhesive join and pulling apart. Wear gloves here because the process involves further breaking the glass.

Tip: Be patient while the heat gun loosens the adhesive and be careful not to break the bezel or front frame while removing the glass. You need the bezel intact.

Step 1: Attach fresh two-sided tape to areas of the bezel that have lost their stickiness. Use the existing adhesive where possible. Do not allow tape to overlap the visual part of the glass.

Step 2: Look for any foam padding or seals and reattach. Do not touch the inside of the glass. You won’t be able to get rid of the fingerprints after assembly.

Step 3: Thread the digitizer cable and remount the new digitizer glass to the bezel by firmly pressing it into place. Then remove any dust from the LCD and glass with canned air.

You may have to assemble and disassemble a few times. The two sets of screws use similar holes. It is easy to insert the initial set of screws into the wrong holes. You will realize that only when the second set does not fit because you already used the hole.

Replacing damaged touchscreens and digitizer panels is not rocket science, but the process does require careful attention to details. Following visual guides and screenshots can make the difference between initial success and having to make second or third efforts.

When a laptop screen breaks, you’ll see various visual defects depending on precisely what broke. You may notice stuck, or incorrectly colored pixels, lines of color, bleeding colors, chunks of the screen appear black, or the screen may not turn on at all.

When a laptop screen is physically broken (such as a cracked screen), it’s usually due to physical damage. You may have dropped the laptop or dropped something on it. A laptop screen can even break if there is something as small as a bit of sand between it and the keyboard.

To fix your broken laptop screen, you’ll have to try each of these fixes. If the screen starts working, or you see enough improvement to begin using the laptop again, you can stop. If it stops working again in the future, return to the list and try the rest of the fixes.

If your screen is physically cracked and the underlying panel is damaged, these fixes won"t work. To fix a physically cracked or broken screen, the only option is to replace the screen.

Restart your laptop. The screen not appearing to work may be caused by an operating system issue, or some other conflict will be cleared by simply restarting the computer. Since restarting is so easy, it should be the first thing you try.

Close the laptop and reopen it. Examine your keyboard and screen areas for any debris, and clean them thoroughly. If your laptop uses a visible latch, clean the latch mechanism. Carefully close the laptop, ensure it is completely closed, and open it back up. If the screen sometimes turns on and sometimes doesn’t, you probably have a bad lid sensor.

Plug in an external monitor. If your screen is entirely black, try plugging in an external monitor. If the external monitor doesn’t work, your laptop may not be on, or it may be asleep or in hibernation mode. Plug it in, and make sure it"s on.

Update your video drivers. If your screen isn’t completely black, but you see visual defects on the screen, try updating your video drivers. You may have a malfunctioning or glitchy driver.

Try to unstick your stuck pixels. If you’re dealing with one or more stuck pixels, you can use an app to try and unstick them. These apps typically cycle between colors rapidly or generate digital snow to force a dead or stuck pixel to start working again.

Try to fix your burn-in. If it looks more like you have ghosts of old images stuck on your screen, then you can try a white screen saver or a few other potential fixes to remove the burn-in.

Check your screen and backlight connections. If you have experience with disassembling laptops, you can remove the bezel around your screen, hinge covers, or other case components to reveal the screen and backlight wires and connectors. Make sure everything is fully seated and the cables aren’t crimped or broken.

Replace the screen. If nothing else works, then your screen probably has to be replaced. Screens with large black or colored bars, black holes, or colors that seem to run are typically beyond repair. If it"s a cracked screen, that’s also a clue you’ll have to replace it.

Make use of your broken laptop by salvaging the hard drive as an external hard drive and selling any other parts that still work. If the display still works, use it as a standalone monitor. If you decide to sell your laptop, perform a factory reset to wipe your personal files.

Getting your screen professionally repaired will likely cost $200 or more. You may be able to find a screen and replace it yourself for less than $100. Before you spend money on repairs, consider upgrading to a new laptop.

Check and replace the power supply if necessary. Detach any bootable media drives, docking stations, and newly installed components that could be interfering with startup. You may need to clear the motherboard CMOS by reseating the CMOS battery.

Even if your tablet is in a case, there’s always a risk it could end up with a broken screen one day. Whether you drop it, sit on it, or expose it to extreme heat, it’s not that hard to crack the glass digitizer or the LCD below it.

If that happens to you, is there any chance you can actually replace your tablet screen with a new one? The answer is yes, but how easily depends not only on your own skills but what model of tablet you have.

Before you do anything, you should Google your tablet to see if anyone else has successfully fit one with a new display. Make sure you search for the exact model. You should hopefully find teardown guides and YouTube videos that demonstrate how to get the tablet apart and fix it.

Doing your research beforehand will enable you to see how difficult it is to replace the screen---if it’s possible at all. You might decide it’s not worth the expense or that it’s best left to a professional.

To find a new screen, just Google the name or model number of your tablet, followed by “replacement screen”. There are numerous specialist sellers who stock replacement parts for tablets. Make sure to read customer reviews to help you find a reliable seller.

Another good source of spare parts for tablets is eBay. Again, be sure to search for the exact model of tablet you want to fix, because even different iterations of the same device can have different screens. For example, the 2017 Amazon Fire HD 10 will have a different screen to the 2019 edition.

As always, look at eBay sellers’ feedback to help you decide on who to buy from. Watch out for items coming from China too, as they will usually take a long time to arrive and may incur import fees.

You may see digitizers being sold separately from LCDs. While it"s possible to replace these separately, they"re normally glued together, making it extremely difficult to separate them. In most instances, you should buy a combined digitizer and LCD unit.

You’ll often get some of these tools included with your replacement display. However, the quality varies, and there’s no guarantee they’ll fit your tablet. If you find that’s the case, then you should look to buy better tools separately. Toolkits for opening phones and tablets can be found online for a few dollars.

For most tablets, you’re also going to need a heat gun to get the screen and the back casing off. It’s common for them to be glued in place, and warming that glue makes it possible to unstick it.

You’ll also need to replace the glue. There are specialist glues you can use for this purpose, but other adhesives may work as well. Just don’t use anything brittle like superglue or weak like wood glue. In a pinch, double-sided tape will work, but only short-term.

If you’re lucky, this is a simple case of pulling off the back or using your spudgers to pry it away. Unfortunately, most tablets these days are glued together---front and back. There are some signs that manufacturers are open to making their devices more repairable, but there"s still a lot of work to be done in this area.

If your tablet"s back case is glued on, you’ll need to carefully warm the casing around the edges using your heat gun. Then you need to push your spudgers between the back case and the body of the tablet to break the glue and get them apart.

When you’ve gained access to the insides of your tablet, you will probably have to remove most, if not all, of the components before you can safely take the screen off. That usually means the battery, the motherboard, cameras, various other cables, the power switch, and the display itself.

If, like most tablets these days, yours has a glued-on screen, you’re going to need your heat gun again. One section at a time, carefully warm up the edge of the screen with your heat gun, but don’t linger in one place too long---you don’t want to melt any plastic parts below the glass.

Next, try to push a plectrum or credit card between the glass and the body of the tablet. It should go in with a little force, but if it doesn’t try warming up the screen some more. Once you get the plectrum in, try to slide it around under the screen, further breaking the glue.

Alternate between heating the screen and prying it away. Ideally, you won’t break the glass in the process, but it’s not a problem if you do. After all, the screen is already broken.

After removing the old display, put your new screen in place, and replace the motherboard and battery. Reconnect all the cables and cameras. Attach the cable for the new display then replace the screws.

Before going any further, this is a good opportunity to test if the new display is working. Turn on the tablet, check you get a picture, and that the touch functionality is operating as normal.

Assuming all is okay, return the back casing to how it was originally. Then glue the screen on, and use clothes pegs to hold it in place while it dries.

While it’s usually possible to replace a broken tablet screen, it’s not always easy. Whether it’s worth it depends largely on how much a replacement display will cost you, compared to the price of just buying a new tablet.

While you might enjoy the challenge, fixing your own electronic devices is always going to be a risk. It’s usually much cheaper than buying a new tablet or paying a repair shop, but if you get it wrong, then it’s money down the drain.

The most important thing is to do your research before you start. If it’s too expensive or beyond your abilities to fix your tablet yourself, it’s best to find out sooner rather than later.

There is nothing more heartbreaking than to see your phone’s screen getting cracked from a simple drop. I know I"ve been there plenty of times with cheap to expensive smartphones. Though getting a phone screen cracked is a quite common problem, you need to know some ways to cope with the cracked screen. Have you noticed that once the screen gets a minor crack, it starts spreading? If so, you may be wondering how to stop a crack from spreading on phone instead of replacing or taking it straight to a service store. You need to take preventive actions to stop the spreading of the cracked phone. Here are some of the best ways, that I"ve learned as well as what industry professionals recommend doing:

First, you need to assess the damage and know if your phone’s screen has shattered. There is a chance that there are some small glass particles here and there. So, be very careful and do not cut your fingers. Assess whether the screen of your phone has cracked, or fully shattered. Depending on it, there are some temporary solutions that you can try. Also, you need to determine whether the screen is actually damaged or just the protective layer on it.

Why is it important to take immediate steps when the screen is broken? Of course, the smartphones are designed in such a way that the dust, moisture and debris are kept away from entering into the machine. Once the screen cracks, that protection is compromised and your phone is vulnerable to moisture and dust.

If it is just a crack on your phone’s screen, then you can apply a temporary seal to prevent the crack from spreading or growing further. For this temporary seal, you need to apply a compound called cyanoacrylate. Tilt the phone back and forth for covering the entire crack properly. You have to apply it evenly and wipe away any excess left over. Now, let the glue dry first before using. Be advised that this is not a preferred method, and is only a temporary fix. You can also apply a screen protector to cover the crack until you get it professionally repaired.

If your phone screen is cracked to a great extent or shattered, then it is best for you to visit a professional. Take your phone to a service center or a  mobile repair professional to get the screen fixed. It is important to take a permanent step in repairing the screen in order to avoid the dust and debris from getting into the phone. Also, this will help you to stop the screen from cracking further causing more problems.

An alternative to replacing a cracked smartphone screen, using the above steps will help stop a crack from spreading on the phone. As always, DIY projects can cause more havoc if user error occurs, so consulting or having the phone serviced at a repair shop is always the best solution. Plus, it usually comes with a warranty.

For many shoppers, there’s comfort in choosing a familiar brand. But before you buy a new TV, there’s something you should know: Even if a TV carries a brand name you recognize, that model might have little connection to the company that built that brand over the course of decades.

For example, RCA, an iconic TV brand, now appears on sets produced by Curtis International, a Canadian company. Sharp TVs? For the past several years they’ve been manufactured by the Chinese TV brand Hisense, but the brand recently changed hands again (see below).

“For many years, TV making was limited to the few large consumer-electronics companies that could afford the investment,” says Paul Gagnon, senior research director for consumer devices at Omdia, a market research firm. But then it became easier to source components, which in turn increased competition and lowered pricing and profits. “For some brands,” he says, “the TV business here in the States was not profitable anymore.”

Companies including JVC, Magnavox/Philips, and Toshiba exited the U.S. market, licensing or selling their brands to companies in China, Taiwan, and elsewhere looking to break into the U.S. market.

Consumer Reports has seen a wide range of quality in televisions carrying licensed brands. For instance, some Hisense-made Sharp sets have done well in our TV ratings—its higher-end sets even rival some of the top models from the dominant brands—while others didn’t do as well. Meanwhile, several RCA- and Westinghouse-branded sets are near the bottom of the list.

One area where many of these licensed TV brands fall short is in HDR performance, which can present brighter, more vivid images with greater contrast and a wider array of colors, much closer to what we see in real life. We’ve also found that many also deliver less-than-compelling sound compared with sets from the major brands.

No matter which kind of TV you buy, it’s smart to use a credit card that doubles the manufacturer’s warranty. Some retailers, such as Costco, grant you the same, or an even a better, cushion. This is particularly important with licensed brands because the manufacturers’ warranty periods may be shorter than what the major brands provide. And it might be tougher to get a licensed-brand set serviced, especially if it requires parts from overseas.

You can also ask retailers for a 30-day guarantee that allows you to return a TV if you’re unhappy with the picture quality, even if that goes past their normal return window.

Below you’ll find a list of licensed TV brands and who makes their sets. (If you’re reading on a phone, you can rotate the device to landscape mode for a better view of the chart.)

AmazonIn 2021, Amazon launched its first two series of Amazon Fire TV Edition televisions under its own brand. Previously, they’d been available from a few TV brands, including Insignia, Pioneer, Toshiba, and Westinghouse, in the U.S. market. The sets are sold exclusively through Amazon’s website and at Best Buy stores.

InsigniaInsignia is Best Buy’s value-oriented house brand for consumer electronics products, including televisions. Insignia, with TVs made under contract by several TV manufacturers, is one of the few TV brands that offer both Amazon Fire TV and Roku smart TV platforms.

JVCThe JVC TV brand was licensed to the Taiwan manufacturer AmTran until 2018, when that license was acquired by Shenzhen MTC, a Chinese TV company. The TVs are marketed here in the U.S. by JMC, a company based in Irvine, Calif. JVC is among several brands that sell smart TVs using the Roku TV platform.

MagnavoxOnce a U.S. TV market leader, the Philips-owned Magnavox brand is now licensed by Funai Electric. The Japanese manufacturer also controls the U.S. licenses for the Emerson, Philips (see below), and Sanyo brand names. As a historical footnote, Funai was the last remaining company to make VCRs; it stopped producing them in 2016.

OnnOnn is a Walmart private-label house brand for a variety of electronic products, including TVs and soundbars. Walmart doesn’t disclose which companies are making the products, but if you look through its TV manual, you’ll see that warranties are the responsibility of “Element TV Company,” the same company that handles Element TVs, and a company that assembles televisions in South Carolina.

PhilipsThe Philips brand in the U.S. is licensed to Funai, a Japanese company, via a subsidiary called P&F USA. A multiyear licensing deal—which also includes the Magnavox name—was renewed in 2018, though the company declined to disclose for exactly how long.

PioneerPioneer, with its Kuro plasma TV line, was once lauded as making the best TVs you could buy. But the company exited the TV market in 2010 and sold its home electronics division to Onkyo in 2014. Voxx International acquired Onkyo’s assets last year and reached a licensing deal for the Pioneer and Pioneer Elite brands, but the deal didn’t include TVs. Instead, our research indicates that Compal Electronics, a Taiwanese manufacturer, now has the license for Pioneer TVs in the
