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.

If your phone has image display issues, an unresponsive touch screen or physical cracks or scratches on the glass, this LCD and touch screen assembly is what you need

This is not an easy job for someone who has no technical skills with Disassembling or Assembling Cellphones/mobile phones, so only purchase this item if you know how to install it

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.

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.

What exactly is short in the market? Your iPhone’s screen is one solid unit made up of several elements that are fused together with OCA (optically clear adhesive). The exterior glass, the digitizer panel (touch sensor), the polarizer and LCD panel. The LCD panel is the key component that is in short supply. Originally Apple had 3 manufacturers to produce LCD panels (LG, Sharp and Toshiba). Apple’s authorized manufacturers have the exclusive technology to produce LCD panels. Other Chinese manufacturers can copy the glass, digitizer, polarizers, OCA, flex cables, backlights, frames and everything except for the main component of the LCD assembly.

How were we getting these parts before? A big leak in Apple’s supply chain. The iPhone 5, 5S and 5C all share most of the same raw components including the LCD panel, the only difference is the flex cable and plastic frame. Independent factories in China can produce these components and can manufacture any 5 series assembly from an LCD panel. Shown on the left is a pulse pressing machine, used to connect the flex cable to the LCD. We use one of these to repair LCDs with damaged flex cables.

So what’s happening?A few things, first Apple has cut off LG and Toshiba, making Sharp their exclusive supplier for iPhone LCD panels and implemented very tight security. Secondly, they have had Foxconn destroy stockpiles of series 5 LCD panels to reduce the parts and material leakage to factories that re-engineer them for the independent repair industry. Along with this strategy, Apple has instructed Foxconn to reduce series 6 materials leakage from their manufacturing centers. Lastly, Apple is working aggressively with US Customs to seize inbound parts.

How long is this shortage going to last? In short,we have no idea. At the time of this writing, LCD prices have been steadily rising for 6 months and replacement iPhone 6S LCDs cost twice what Apple charges for their repair service. Apple does not intend to compete with independent repair shops, instead they are squeezing the profit out of the industry. LCD refurbishing may help shops cut cost but without new LCD panels entering the system it won’t last long.

What does this mean for the independent repair community?Apple is the only repair operation that is immune. Even the Chinese LCD refurbishing plants used by the large chain repair companies are running out of LCDs. Continually rising costs may push out the big chains but with lower overhead and clever problem-solving, the owner-operated shops stand a fighting chance.

What can we do?Apple has done everything in their power to protect their repair monopoly. When there’s only one repair shop around, prices and wait time goes up and quality goes down. Apple has every incentive to eliminate the parts market. Don’t let them. Check out the Right to Repair Bill.

China, we’re told, can make anything. If you need some PCBs in a few weeks, there are a few factories in China that will do it. If you need a nuclear reactor, yep, there’s probably a factory in China that’ll do it because nuclear reactors are listed as one of the items facing new tariffs when imported into the United States. No, I am not kidding. What about LCDs? What about old-school character LCDs? Is it possible to find a factory in China that will make you the LCD you want? That’s what [Robert Baruch] will find out, because he’s repairing an old computer with new parts.

The object of this repair and restomod is a TRS-80 Pocket Computer (PC-1), otherwise known as the Sharp PC-1211. It looks like a calculator, but no, it’s a legitimate computer you can program in BASIC. [Robert] bought this computer for a bit more than $5 on eBay ‘for repair’, which means the zinc-air battery was dead, and unfortunately, the LCD was shot. The LCD technically works, but it just doesn’t look good. Sometime in the last thirty years, moisture got in between the layers of glass, polarizing film, and liquid crystal. This is not unique to [Robert]’s unit — a lot of these PC-1s have the same problem, many of these broken seals rendering the computers themselves useless.

This is an ancient computer, and replacements for this LCD are impossible to find, but because the Sharp PC-1211 is well documented, it is possible to find the datasheet for the original display. With that, it’s just a question of finding an LCD manufacturer that will do it. So far, the costs look good — $800 USD ($300 for tooling and 10 samples, $500 for another 200 LCDs) is what it’ll take to get a few units. [Robert] already has a few people interested in repairing their own Pocket Computers. You can follow the eevblog thread here, or check out the video below.

Since the iPhone 7/7 Plus has been released for quite a long time, finally the China made iPhone 7/7 Plus screen replacementscame out in the market. we’ve got some iPhone 7 series LCD screen replacements samples and done some tests on them, now let’s take a closer look at these new iPhone 7 series LCD screen replacements!(TianmaandLGsources for testing)

After installing all the sample screens to the iPhone 7/7 Plus rear housing assembly, we found that all the China made iPhone 7 series screen replacements are fitting well just like the original ones - the home button fits well, the screen assembly and the rear housing also fits well.

From the picture below, we can see that there is no difference between the China made iPhone 7 series display and the original ones, however, back to the rear side, we can easily figure out which one is which, cause the original one has Apple logo on it while the China made screen has none.

By comparing these two iPhone 7 screens, we can find that the screen flex cables are much different, there are extra IC on the China-Made iPhone 7 screen while the original one has none. And the original iPhone 7 series screen flex cable is integrated together while on the China-Made iPhone 7 series screen the touch function flex cable is soldered to the display and 3D touch flex cable.

Another difference between the original and China made iPhone 7 screen replacements is the exposed IC on the after-market iPhone screen, just like other China-Made iPhone 5 or 6 series screen replacement, which has more potential risk of electrostatic damage and more likely to get damaged and this problem needs to be improved.

During our test, we found that the display color between our after-market iPhone 7 screen and original screen seems a little different although they are not effecting the touch function. And to be honest, there may have some black dots on the screen because of impurities within the screen module when laminating the LCD and backlight together, without any doubt, this can be solved with technical improvement.

The screen touch sensitivity is another big concern for all of us, luckily, during our test, almost all home button and touch functionality on both iPhone 7 and 7 Plus works well, except one piece of iPhone 7, the 3D touch function is not acting so well on the central part of the screen.

The China-Made iPhone 7 series LCD screen assembly replacement still remains to be improved in quality and performance compared to the original ones, the exposed IC, heavier screen flex cable ribbon, and the screen color difference, the touch function stability, although the price is attractive. However, the China made iPhone 7 series screen replacement is under the improvement, and sooner or later their quality and performance can be quite close to original ones and acceptable, if you"re going to stock up some non-original iPhone 7 series LCD screen replacement, pay more attention and we’ll keep you updated with further information about after-market iPhone 7 series screen replacement!

Unfortunately, in most cases, you cannot fix a broken TV screen. TV manufacturers do not sell screen replacements, and there is no secondary market for used screens. That’s because the screen is the most expensive part of the TV, by far. Replacing it would cost more than buying a new TV!

In many cases, your local electronics or TV repair shop won’t even consider working on your broken TV screen. They know that it’s just not worth their time.

If you bought your TV recently, chances are incredibly high that it came from China. Specifically, the BOE Technology factory in Hefei, the capital of China’s Anhui Province.

The BOE factory, where most US TV screens are made today, is almost a mile long and cost about 7 BILLION dollars to build! Sony, Samsung, LG, Vizio, etc. all buy their TV screens from BOE.

“Liquid Crystal display screens are made by putting two thin sheets of glass together. On one of the sheets transistor “cells” formed by first depositing a layer of indium tin oxide (ITO), an unusual metal alloy that you can actually see through. That’s how you can get electrical signals to the middle of a screen.

Then you deposit a layer of silicon, followed by a process that builds millions of precisely shaped transistor parts. This patterning step is repeated to build up tiny little cells, one for each dot (known as a pixel) on the screen. Each step has to be precisely aligned to the previous one within a few microns. Remember, the average human hair is 40 microns in diameter.”

This is the number one reason your TV screen is so costly – they are incredibly challenging to build, and as a result there are only a few companies in the world that make them.

I’ve also heard that only 1 out of every 3 TV screens pass testing at the END of the manufacturing process. That means 2 out of every 3 screens made are worthless!

The screens are made in China and then have to be shipped across the world to be sold in the US. The cost to ship them is high, and a lot of damage can happen during the journey.

So the complexity, and shipping both contribute to the high cost of TV screens. It’s why no one sells the screen separately, it just doesn’t make financial sense.

If your TV screen has an imperfection, discoloration, lines, streaks, spots, etc., then there is a good chance that your warranty will cover it (if it’s within the allotted time period). Most TV warranties are in place for the first year, and they cover these types of manufacturer defects.

And the even better news here is thatthe majority of issues you’re likely to encounter with your TV will happen within the first year (when you’re covered by the manufacturer).

You can always try selling it. Your broken TV isn’t worth much, but to the right person, it’s worth something. Someone who knows what they are doing will take your TV apart, and sell off each individual piece.

Technically, you could do this yourself, but it’s time consuming and you risk damaging the parts. I wouldn’t bother. Instead, try listing the whole TV for sale. Getting something for a broken TV it is better than nothing.

If it turns out no one is willing to buy it, you can try listing it on those same marketplaces for free!Tons of people usually respond when they can get something for no cost, even if it’s broken.

Find a local electronics recycler. There are a lot of these out there. You can look up the closest one to you using Earth911’s website. Type in “TV” and then your Zip Code to find the nearest option to you. Once you find the closest location, you just have to drop off your TV.

Local electronics stores typically recycle products that they sell. A great example of this is Best Buy. They have a nationwide recycling program. But keep in mind, they will charge you a small fee!

Your town likely collects e-waste. Check out your town/cities trash website and see what their policies are for electronic waste. Some towns have special pick up days, others have drop off locations. I would just call your city’s public works department and ask for a place to recycle or dispose of old electronics.

Buy a TV screen protector. You can buy a screen that covers your TV and protects it against damage, and many are waterproof! These provide great added protection from possible bumps and contact with liquids from pets and children.

Mount your TV on the wall.This way your television is up off the ground, and out of reach. It won’t stop your kids from throwing a toy at it, but at least they can’t bump into it, or accidentally knock something, or someone into it.

Don’t allow video games. This might sound harsh (especially for the kids), but I’ve heard too many stories of Nintendo Wii controllers being accidentally thrown at the TV. If you don’t hook up a video game console to your TV, this can’t happen.

Most TV repair shops won’t even bother trying to fix a broken screen. In the end, between a screen replacement and the repair costs, you’d spend the same amount for a brand new TV!

If your TV is cracked or damage because of something you did, your warranty is unlikely to cover it. In that case, consider selling your broken TV or disposing of it.
