how to clean ipad lcd screen made in china

I used to have this same problem, but not any more. I came up with the perfect method of cleaning the LCD panel. First of all, I had no idea that alcohol would damage the LCD. I normally use 90% Isopropyl Alcohol for cleaning everything on the smartphones and tablets that I repair. I might change that back to a pre-mixed 50% solution, but the 50% does not remove grease as well. I honestly don"t think a 1-time cleaning using the 90% will cause a problem. I could believe that continued cleaning with the alcohol could cause damage, however.

What works best for me is to follow this 3-step procedure. And take note, scrubbing an LCD with a back-and-forth motion will only get you frustrated, just as the previous poster had mentioned. I"ve been there, rubbing on an LCD for upwards of an hour, only ending with the same grease smudges that I started with. Well anyway, here"s my 3-step process:

1. Using a micro fiber or dust-free cloth, or even a soft toilet paper, put a liberal amount of the alcohol on your cleaning cloth and use "flood-strokes" on the LCD in one direction ONLY. Wipe down the LCD in as few strokes as possible, as wide of a stroke as you can with your cleaning cloth or TP. You should use enough alcohol that it leaves a wet film on the LCD.

2. Blow dry (with your mouth or a heat gun on low) the alcohol. It will disappear very quickly. If you see any spots, repeat step 1, and then do this again. You will see residue on the screen, but it should be very uniform, and in the direction that your flood strokes were in step 1. If you do this right, you may not see any streaks at all.

3. Using your hot breath (hopefully your breath isn"t so bad that you melt the LCD, so be careful here), steam up the surface of the LCD and use the lint-free cloth to wipe the steam. This will get rid of all the residue left behind by the alcohol. It"s okay to wipe in a back-and-forth motion when using the hot-steamy-breath application of moisture. In only 5 minutes, your LCD should be completely free of streaks, grease, and dirt. Blow away any excess lint, and get the glass digitizer put on it as quickly as you can before your LCD attracts dust out of the air.

One thing I would also recommend is that you have a good filter in your HVAC system. Some people I know of actually use a hood that forces air through a filter, and into the hood. This way, you don"t have any ambient air coming into contact with your LCD, because you are operating in a positive-pressure environment with incoming air that is filtered, and thus exhausting into the room after leaving the hood.

I will be writing a post on this and possibly doing a video for my blog site, which is the Carlton Zone Blog. Check the site soon. I would be glad to post videos and advice for repairs, because I do a lot of this.

The way you clean your computer screen largely depends on what it"s made of - you have to be more careful with LED/LCD screens than glass-coated ones.

We"ve all had that moment - you"re sitting at your desk on a normal workday, then the sun starts shining directly on your screen, and you realize you don"t know when you last cleaned it. In fact, it may have been so long that you"ve forgotten how you"re supposed to clean it.

If this sounds like you, don"t feel too bad - most experts recommend that you should only clean your computer screen every three to six months. So if you"ve waited half a year since the last time you cleaned, it makes sense that you might not remember all the do"s and don"ts of the process.

Here"s a helpful guide to help you remember exactly how to clean your specific computer screen, whether it"s a Mac or PC, including which products you should and shouldn"t use for your specific type of display.

Glass-coated screens: The screens you find on most Mac computers are glass-coated. Displays like this are a little less delicate than LED or LCD screens.

LED/LCD screens: These screens are mostly found on Windows computers. Unlike glass-coated screens, they"re made up of tiny liquid crystals and can be very easily damaged if you"re not careful. Most touchscreens and matte displays are LED/LCD.

You may want to look on your manufacturer"s website and check what kinds of solutions are safe for the screen type you have - factors like whether your screen is matte or a touchscreen may affect this.

If you have a glass-coated screen on your computer, you have a few more options as to what cleaners you can use, but you should still be careful. You can use one of the solutions listed above, but you can also use:

Turn off your computer before cleaning - this is just safe practice where any amount of liquid is involved, but more specifically, any static on the screen could create a shock and damage the internal components.

Use filtered or distilled water if you need to use it, especially in areas with hard water - minerals like calcium and magnesium in the water you use could also damage your screen.

Wipe in tight, Z-shaped motions, or directly up and down or side to side. Wiping in circles can create uneven pressure and ultimately lead to screen damage. It"s also more likely to create streaking.

Use any fabric that feels rough to the touch - even a fabric as soft as a cotton shirt has snags and uneven parts that can damage a computer screen. Microfiber cloths are ideal because the fibers are so tiny that they can cover every inch of the screen with even pressure at the same time, eliminating any opportunity for scratches.

Spray any cleaning solution directly onto the screen. To avoid any risk of damage from excess moisture, spray the solution directly onto the microfiber cloth instead.

Apply pressure when you clean the screen. This will likely damage the internal components of the screen and could leave scratches or spots of discoloration or dead pixels that won"t go away.

Even if you"re working on a particularly stubborn spot, don"t scrub - rather, leave the damp cloth sitting on the screen for several minutes, then try to gently wipe it away again.

Once you"ve turned off your computer and dusted off the screen, mist a dust-free side of your microfiber cloth with a cleaning solution that is safe for the type of screen you have.

Wipe the screen in a consistent, non-circular motion without applying too much pressure. Make sure no moisture accumulates, especially at the corners - if it does, use a dry corner of microfiber cloth to gently wipe it away.

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!

It can be really frustrating to find several fingerprints on the display of your smartphone. Unfortunately, most smartphones today do not support fingerprint resistance. Thus, there is a continuous need to always wipe our smartphone screens to make them look cleaner. While many people are comfortable with a simple wipe using any clean cloth, some are not. Some users believe that they need some sort of disinfectant to make the smartphone screen clean. During the pandemic, various alcohol-containing disinfectants and cleaners have become common household items. We hold mobile phones in our hands every day and they can easily get contaminated with various pathogens. Since various alcohol-containing cleaners can not only clean oil stains but can also kill germs, wouldn’t it be appropriate to use them to wipe the smartphone screen? Well, don’t be too sure about how appropriate alcohol is for cleaning a smartphone screen.

While you may be tempted to use alcohol-based disinfectant to wipe your smartphone screen, please don’t. This is because if you do it incorrectly, it is likely to damage your phone or other electronic devices. Because using alcohol to wipe the smartphone screen is likely to cause irreversible serious damage to the screen. This is particularly true for LCD screens. So, why does alcohol have a strong erosive effect on LCD screens?

The liquid crystal screen is composed of multi-layer materials and its core is a sandwich structure with a layer of liquid crystal molecules sandwiched between two polarizers. Both the polarizer and the liquid crystal molecules themselves are very soluble in alcohol. Once corroded by alcohol, they will dissolve immediately and the screen will become mottled.

However, modern LCD screens, especially various touch screens, are not so fragile. Because we will also set a glass cover on the top layer of the screen, this cover mainly prevents scratches from damaging the screen. Furthermore, this later can naturally block various moisture and solvents from the outside from directly interacting with the structure below. But even so, wiping the screen with alcohol-based cleaners is a dangerous practice for two main reasons.

First, the surface of the glass cover is actually coated with a special organic film, such as an oleophobic film. This can reduce oil adsorption and ease fingerprints from dirtying the screen. Most of these coatings contain various organic compounds, and their resistance to alcohol is very weak. If they are wiped with alcohol from externally, the coatings are more likely to fall off. This will cause the display to become blurry. Of course, if the screen of the mobile phone is covered with film, then there is no need to worry too much about this problem.

Second, although the top layer of the LCD screen, that is, its surface is not so squeamish, its sides are still very fragile. Most of the LCD screens damaged by alcohol are actually because the alcohol penetrated into the gaps on the side of the screen. This means that as the user wipes with alcohol, the alcohol, finds its way into the sides of the display. It manoeuvres from the glass panel and drills directly into the lower structure. The surface tension of alcohol is weak and the capillary effect is strong. Once it finds its way into the side of the display, it will quickly penetrate into it. As we will all expect, the consequences are naturally very irritating.

If somehow, a small amount of alcohol enters the inside of the screen, you can immediately turn off the device to dry naturally. Alternatively, you can use a hairdryer to dry it carefully and this will not affect subsequent use.

From time to time, there is usually a need to clean the display of our smartphones. We also need to clean the screen of our tablet or computer. When we have such a need, all we have to do is spray some special LCD screen cleaner and wipe it with a soft cloth. This will make the screen clean and appear brand new. The LCD screen cleaner has a very good removal effect on fingerprints and oil films, and many wet wipes also have similar functions.

The active ingredients contained in these cleaning products are mainly surfactants. They have a good cleaning effect on oil stains and will not damage various organic coatings. If there is no similar cleaning agent, the LCD screen can also be cleaned with a damp cloth dipped in a very small amount of pure water. However, be very careful not to let water flow into the gaps around the screen.

To sum up, if it is just for cleaning, it is not safe to use alcohol. If there is a need for disinfection, then you should be cautious. Some mobile phone products will be sterilized with alcohol. It is recommended to read the instructions before disinfection. In addition, when disinfecting a mobile phone with alcohol, it is also recommended to first dip the alcohol on a soft cloth, and then gently wipe it with the soft cloth. Do not spray or pour alcohol directly on the screen, so as to prevent the alcohol from flowing everywhere and increase the risk of eroding the original screen and damaging the mobile phone.

There are multiple types of LCD screen cleaners that users can purchase off the shelf. If you feel that a simple cloth wipe is not enough, then try and purchase any of the LCD screen wipes on the market. As much as you can, try to avoid the use of alcohol or alcohol-based disinfectant to clean your smartphone. The adverse effect of this could be worth much more than the need to clean or disinfect the device.

Garmin, Avidyne, and Dynon all publish recommendations for their own equipment, but they essentially agree on the technique. For the displays themselves, get the cloth wet with the alcohol solution and wipe the screen area that people touch. You shouldn’t have so much liquid it runs down the screen as you wipe, but it’s good to see some moisture left behind on the screen.

Leave the screen wet for at least 30 seconds. This detail is overlooked by some and important if you want sanitization. You can let the alcohol solution evaporate off, or you can clean it with a microfiber cloth or avionics screen cleaner like iCloth. Just remember: Sanitize first, then clean. Include your iPad or other portable avionics in your cleaning as well. You can’t infect yourself, but your iPad could be a vector into the cockpit for something that affects others.

Never use ammonia or bleach cleaners (like pre-moistened Clorox wipes) on any avionics surface. They can damage the anti-glare and oleophobic coatings on screens and can even remove the painted text on the bezel. In truth, even alcohol can affect oleophobic coatings, but there’s not much you can do there. Don’t use paper towels on any glass surface as it can leave tiny scratches.

As for the rest of the cockpit, wiping with isopropyl alcohol or a solution of 10-percent Clorox in water will disinfect other surfaces such as the flight controls, power quadrant, etc. The same caveat applies about not getting water inside items—like the push-to-talk switch on the yoke—and letting surfaces stay damp for at least 30 seconds before wiping away any excess. It might help to go through your start and runup checklists to see all the items you touch … it’s amazing how many things there are.

Don’t forget about your headset, and especially the mic which its right at your lips. Consider leaving it in the bag until it can go straight to your head. Wiping it down before and after use isn’t a bad idea, either. Likewise with oxygen masks or cannulas.”

Wired reported Friday that only one display manufacturer, Samsung, was supplying Apple with the Retina display for its new iPad. Although a conflicting report from Reuters has surfaced today, IHS iSuppli analyst Vinita Jakhanwal stands by what she originally told us. In last week"s article, she said, “Meeting pre-order demand is still a concern. A single display supplier doing this will be challenging."

Our Friday story was corroborated on Tuesday by a Bloomberg report that also quoted Jakhanwal. And thus began wide speculation over whether Apple would be able to fulfill demand for its third-generation tablet.

But the story took a 180-degree turn early today when Reuters reported that a source "close to the matter" says both LG and Samsung are in full swing producing the high-resolution display. Wired reached out for comment from Samsung and LG. Samsung told us it has nothing to comment, and we hadn"t yet heard from LG by press time.

"Apple has likely qualified three sources for display of the new iPad, and we are maintaining that. We haven"t changed our position from there. All three suppliers have been working to reach mass volume production to meet the launch of new iPad, but at this point, it’s likely that the most volumes may be coming from Samsung. LG and Sharp are likely to pick up volume production soon, in April."

Shipping date estimates for the new iPad have recently slipped: Customers ordering today are facing two- to three-week delivery waits, suggesting demand is intense, and supplies are limited. Demand for major new Apple products like the iPhone and iPad is always extremely high, making it difficult to tell whether sheer consumer interest is increasing shipping delays, or if production isn"t ramping up quickly enough overseas.

Producing a 2048 x 1536 display is a technical challenge by any measure, so Apple"s suppliers may be experiencing a brand new set of issues. And one analyst says sales thus far have already broken Apple"s records, but definitive pre-order numbers aren"t yet known. The third-generation iPad goes on sale at Apple Stores starting at 8 a.m. on Friday, March 16.

Apple is always looking to diversify its suppliers; this helps to improve existing technologies and make them less expensive. This time, TCL’s subsidiary CSOT wants to enter Apple’s LCD supply chain for upcoming Macs and iPads.

The publication says that CSOT is a “fierce competitor” to BOE in the global LCD market, but the company is ahead of CSOT in LCD panels for notebooks, tablets, and monitors as well as with the OLED technology for smartphones.

BOE, as you probably know, has for years been a third supplier of displays for Apple’s older LCD iPhones, but only started making OLED panels for Apple as of the iPhone 12. It was on track to pick up orders for 30-40M iPhones this year. It will also be responsible for around five million units of iPhone 14 OLED panels.

Not only that, but BOE is also supplying LCD panels to Apple for MacBooks and iPads. Analyst firm Omdia says the Chinese company will be the largest supplier of LCD panels for iPad this year.

CSOT also formed a team during the first half of the year to review building an OLED production line aimed at iPhones. CSOT’s expansion plan will, besides BOE, also threaten South Korean display maker LG Display, which leads the supply of LCD panels to Apple for high-end devices.

LG Display is expected to supply 14.8 million LCD panels to Apple for MacBooks this year, according to Omdia, making its share in this specific supply chain 55%. Having another competitor in the supply chain like CSOT could add pressure on LG Display to cut unit prices.
