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.

Researchers said about a quarter of the chemicals from screens they tested might be pollutants. Photo: Getty alt=Researchers said about a quarter of the chemicals from screens they tested might be pollutants. Photo: Getty

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.

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.

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.

Scientists say cracked screens and leaking chemicals are a worldwide problem. Photo: Shutterstock alt=Scientists say cracked screens and leaking chemicals are a worldwide problem. Photo: Shutterstock

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.

"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.

Broken screen replacement service is provided from thousands of repairs stores and phone parts wholesalers worldwide, iPhone of which are mostly engaged in. So how to purchase reliable LCD screens among so many quality grades from China suppliers? Let me firstly elaborate on the quality grades of the iPhone LCD digitizer assembly that most repair stores and traders used to replace the broken ones.

According to the investigation, 90% of the Chinese iPhone LCD screen suppliers are found selling third-party manufactured screens and seldom sell genuine original LCD screens. Therefore, if your phone screen is broken, there would be a high chance for your screen to be replaced with a non-original one. Why? Maybe the cost and quality are relatively competitive, so why not?

As known, Foxconn is authorized to assemble iPhone, so there are some original iPhone LCD screens leaked from the assemble factory. And there are brought out from the factory for replacement. However the price is definitely high and still, some people care more about the quality of the screen than how much they cost, so for this group of customers, the Original Quality of LCD digitizer assemblies are preferred.

For some LCD digitizers, the LCDs are still working while the front glasses are broken, which can be recycled. Some factories recycled these broken screens by removing the broken front glass and attach a new one, then the LCD digitizer assembly would be new again, which is what called refurbished. Brand new original LCD screens are limited, and the refurbished ones can replenish the shortage of the new original LCD digitizer assemblies, for their quality would be more stable than the third-party manufactured.

Some Chinese factories purchase the original single LCD display, not compete LCD screen from the original factory, and then attach high copy front glass, backlight, etc, materials into a complete LCD screen, which quality is not stable and the display color is slightly different from the ones with high copy backlight. Well, their price would be cheaper and loved by many repair shops and wholesalers.

Under the shortage of original LCD screens, many Chinese factories begin to produce the high copy LCD screen. The stock and supply are getting less and less since about 2015, which leads the price goes higher and higher. Therefore the Chinese manufacturer starts to produce LCD screens with high copy raw materials. With competitive prices and good quality that meet most iPhone users’ needs, they are also popular among many wholesalers and repair shops.

With the premium quality of LCD and OLED screens tested strictly, we’ve helped many clients enlarge their markets worldwide. If you wholesale the LCD digitizer assembly or retail them in your repair shop, more information and sample are supported for your reference, please do not hesitate to contact us or leave your comment to discuss more.

Have you ever been on a train and had the sun shine on your book from behind you making it hard to read or on your smartphone screen creating a glare and making it hard to see?

When you"re working on your PC, similar poor conditions may develop without you realizing it. For example, if the lights are near the center of the room, and your PC is set up with you facing the wall, although the level of brightness is different, you could experience something similar to sunlight shining on your screen from behind you like on the train. If that"s the case, consider changing the layout.

What can further worsen your eye fatigue in a situation like this is the light reflected from your display. Shiny glare panels are made to provide accurate blacks and colorful display, so they are good for watching videos, but they also tend to reflect outside light. In an office or similar setting, lights and other displays can be reflected on your screen, throwing off your focus and causing eye fatigue.

For regular PC work, an LCD with a non-glare panel that does not reflect light is easier to use. If the product you"re currently using has a glare panel, you can affix low-reflection film to the screen.

Fluorescent lights are brightly reflected on the glare panel, making the screen hard to see. These conditions can easily strain your eyes (left). A non-glare panel can substantially reduce the reflection of fluorescent lights and reduce the strain on your eyes (right). The difference is as plain as day.

It’s also important not to make the lights in the room too bright. It"s common for advice to focus on not letting the room be too dark, but if the lights are too bright, it creates a difference between the screen brightness and ambient light, and that"s also no good. More specific details on screen brightness are provided in Point 5. Also pay attention to the temperature setting on your air conditioner and the direction in which it blows. These things can cause dry eyes, and your seat should never be positioned so that the air conditioner is blowing directly in your face.

Generally speaking, the distance between the user and the screen should be at least 40 centimeters or 50 centimeters in the case of a wide screen. The reason you should be further away from a wide screen is that the wider screen will not fit completely into your field of vision unless you sit further back. The conditions will vary slightly depending on other factors as well, including screen resolution, text size and your eyesight.

No matter what the situation, if you are viewing a screen at a distance of less than 30 centimeters for long periods of time, your eyes are obviously going to become fatigued. If you have an A4-sized sheet of paper, hold it up longways between you and the screen on which this article is displayed and see if there is enough room for it to fit. An A4-sized sheet of paper is about 30 centimeters (297 millimeters) long, so if you"re viewing the screen from a shorter distance than this, you"re too close. If you"re viewing it at a distance of about 1.5 times that length, you"re safe for now.

Once you"re at the proper distance from the display, try to have it so that your line of sight is directly ahead or slightly downward when viewing the screen. You should avoid looking up at the screen, because that can cause dry eye.

Displays that do not allow sufficient adjustment of the angle and height of the screen can lead users to adjust their posture to the screen position, which prevents them from working in the correct posture. Choose a display that has rich features including a tilt function allowing the screen to be tilted up and down and a height adjustment function.

The adjustment mechanism of the LCD is also important for working on a PC in a posture that does not strain the eyes, neck and shoulders. Choose a product that allows the screen to be lowered just above the table top and flexible tilt adjustments (photograph: EIZO"s FlexScan EV2436W.

But when you give specific numbers like this, most people have no idea what they mean. So what you want to remember is that the trick to adjusting the brightness is using white paper like copy paper. Compare the paper under the lighting in the room to the screen, and adjust the brightness of the display so that the brightness matches as closely as possible. This will put the brightness at about the right level.

Particularly, when using the display for work, you"ll often be comparing paper documents with documents on the screen, so by adjusting the brightness of the screen to the brightness of the paper under the lighting, you"ll reduce the strain on your eyes, making this an effective measure against eye fatigue.

Put white paper next to the screen as shown, and adjust the display brightness while comparing it to the paper. Screen too bright compared to the paper (left), and display brightness adjusted to appropriate level so that the brightness of the paper and the screen are roughly the same (right).

What you need to remember is that if the brightness of the room where the display is installed changes dramatically in the morning, afternoon and evening, the brightness of the screen needs to be changed accordingly, or there"s no point. If you have to adjust it frequently like that, doing it manually is bothersome, and keeping it up becomes difficult. Consider purchasing a display that comes with a function to automatically adjust screen brightness to the optimal setting according to external light.

The majority of LCDs today have LED backlights. In some cases, the brightness adjustment mechanism (dimming system) causes eye fatigue. Specifically, caution is required with the system called PWM (Pulse Modulation), which is employed by most displays. In this system, the LED element blinking time is adjusted to control the display brightness — extending the time that it"s on makes it brighter, and extending the time that it"s off makes it darker.

For some people, this blinking of the screen is experienced as flickering, leading to eye fatigue. There is a difference among individuals in how this flickering is experienced. Many people using the same display will not notice anything at all, so even in an office where the same model is purchased in bulk, it"s difficult to figure out that the display is the cause.

The only way to prevent this is to address it with the display itself. Some displays prevent flickering by employing special dimming systems such as DC (Direct Current), a system that, in principle, does not produce flickering, and EyeCare Dimming, a hybrid system used in some EIZO products. By purchasing a product like this, you may eliminate eye fatigue for which the cause was unknown.

We"d like to add a note about the EyeCare dimming system. This hybrid system uses DC dimming at high brightness settings and PWM dimming at low brightness settings as it does a better job than DC dimming at reproducing colors at low brightness. PWM dimming is only used at low brightness settings, so the blinking luminance difference is smaller, thereby controlling flickering.

EIZO"s FlexScan EV series employs the unique EyeCare Dimming system. We put a small USB fan in front of the screen to check for flickering. At high brightness, DC dimming is used, and the light emitting elements do not blink, so the shape of the blades appears circular (left). At low brightness, PWM dimming is used, and the blades appear separate from each other, so you can see that high-speed blinking that can"t be perceived is taking place (right).

The reason it has recently been the subject of attention is that there are many LCD products with LED backlights that have a high color temperature display (white appears bluish), and there are more cases where the user is subjected to stronger blue light than with conventional displays, so this type of problem has come under closer scrutiny.

Some methods to address the problem are to wear blue light blocking glasses or to apply blue light reducing film to the LCD screen. Also remember that on products that allow the display picture quality to be adjusted, you can lower the color temperature on the display.

For example, results of an experiment (results of EIZO study) show that if you change the 6,500-7,000K color temperature used in common displays to 5,000K, the 400-500nm wavelengths corresponding to blue light can be cut by about 20%. Furthermore, by adjusting the screen brightness to a proper level that does not cause eye fatigue, you can reduce blue light by a total of 60-70%. Many of the aforementioned blue light blocking glasses only cut up to 50% of blue light, so this is more effective.

However, lowering the color temperature causes the screen display to change to reddish or yellowish in color, and color reproducibility is lowered. For that reason, it"s best if you can lower the color temperature for working with office documents and put it back to normal when doing creative work dealing with photographs and images.

Cutting down on PC and smartphone use before bedtime is also a surprisingly important point. The light put off by PC and smartphone screens, including the aforementioned blue light, is said to be effective in waking you up. Looking at these screens before bedtime tends to make it harder to fall asleep. Considering this, it"s actually not a good idea to read e-books on smartphones or tablets before bedtime.

For example, EIZO"s FlexScan EV series of LCDs places emphasis on addressing eye fatigue and has features to address points 1 (installation environment), 2 (posture during use), 3 (proper rest), 5 (brightness), 6 (flickering) and 7 (blue light) above.

In Paper mode, the color and contrast display is similar to paper. With this excellent feature, the color temperature is lowered instantly with the touch of a button, and blue light is substantially reduced (left). If you use the Auto EcoView function, the built-in illuminance sensor detects ambient brightness and automatically takes the display brightness down to the optimal level in real time (right). The aforementioned EyeCare Dimming system suppresses flickering of the screen display at the same time.

The value of considering replacing the display itself is significant as a trump card for addressing eye fatigue. At home, it will help protect your eyes and the eyes of your loved ones, and at the office where you sit in front of the screen for long hours, it"s sure to contribute to greater efficiency and an improved working environment.

To resize a LCD is literally to cut the glass, polarizers, circuits and circuit boards to a new size. Years ago, it was thought impossible to preserve the original performance of a previously manufactured LCD once the glass circuits are cut. However, Litemax has done the impossible, over and over again, becoming the world"s leading pioneer and leader in LCD resizing solutions.
