clean ipad lcd panel made in china

If you"ve owned your iPad for more than a week, you"ve noticed that it doesn"t look nearly as good as when it first came out of the plastic. Fingerprint smudges, dust specks, grease streaks - it"s hard to keep a device clean.

With a soft lint-free cloth - a microfiber cleaning cloth that you can find on Amazon is ideal - wipe the iPad"s screen with small circular motions. The iPad"s screen is oleophobic, meaning that any oils or fingerprints should come off easily.

If necessary, lightly dampen the cloth with water or 70 percent isopropyl alcohol. If you do this, make sure to only wipe the hard and non-porous surfaces (the casing and display). This should also help if something is stuck on your iPad"s screen, like a piece of dirt. Just make sure to dampen the cloth itself - don"t pour or spray water directly onto the iPad.

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.

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.

The company was caught having changed the circuit width of the thin film transistors on the OLED panels it made for iPhone 13 earlier this year, people familiar with the matter said.

The Chinese display panel sent a C-level executive and employees to Apple’s headquarters following the incident to explain why they changed the circuit width of the transistors.

They also asked the iPhone maker to approve the production of OLED panels for iPhone 14, but didn’t receive a clear response from Apple, they also said.

Cupertino seems poised to give the order for around 30 million OLED panels it intended to give BOE before the incident to Samsung Display and LG Display instead.

HONG KONG/TAIPEI (Reuters) - A debt-laden Chinese technology firm seeking to ban all shipments of Apple’s popular iPad tablet into and out of the country has been told that China’s customs authorities are unlikely to intervene in the trademark battle.

Proview Technology, the Chinese company embroiled in a legal battle with Apple Inc over the iPad name, said on Wednesday that customs authorities had told it that the sheer size of the market and the popularity of iPads would make it difficult to impose a ban.

On Tuesday, lawyers representing Proview Technology (Shenzhen) Co Ltd said the company would seek a ban on exports of Apple’s iPads from China, a major manufacturing base, a move that could deal a blow to the U.S. technology giant’s sales globally.

Authorities in some Chinese cities had ordered retailers to stop selling Apple’s iPad due to the dispute. Proview has asked authorities in about 20 cities, including Shijiazhuang near Beijing, to stop the sales.

Apple lost a case to Proview Technology (Shenzhen) in a Shenzhen court in southern China late last year, when the court agreed that Proview owned the iPad trademark. The next hearing for this case is on February 29.

Proview International’s shares last traded at HK$0.20. On Tuesday, Apple’s shares ended at $509.46, setting a record high on hopes of strong iPhone 4S demand and investor optimism over the potential launch of a new iPad in 2012.An employee stands next to an empty display desk which was used to put Apple iPads at a dealership in Hefei, Anhui province, February 15, 2012.

Apple says it bought Proview’s worldwide rights to the trademark in 10 different countries several years ago, including rights to the iPad name from a Taiwan subsidiary of Proview International.

Back then, the Proview Taiwan unit had sold the rights to IP Application Development Ltd, a London-based company that was set up by Apple, for 35,000 pounds, Proview’s executives and lawyers said. IP Application Development then sold the iPad name to Apple for 10 pounds months later, they said.

“We spent a lot of resources on it. It’s the same concept as the iPad today, except that back then, there were practically no LCD screens,” Yang said.

Some analysts also think Apple plans to announce a smaller iPad to safeguard its market share as rivals including Samsung Electronics and Amazon.com Inc begin selling cheaper, seven-inch tablets.

AU Optronics, the world"s No.4 LCD maker, will ship about 400,000 to 500,000 panels in September for Apple"s reported small-sized iPad, Taiwan"s DigiTimes said, citing industry supply chain sources. link.reuters.com/haj62t

The report comes on the day that the U.S. government asked a federal court to impose a $1 billion fine on AU Optronics over its role in a cartel that fixed the prices of LCD panels over a number of years.

She is one of scores of young workers in the city of Suzhou who were poisoned by the chemical n-hexane, which they say was used to clean Apple components including iPhone touch screens.

The chemical"s potential risks are well-known in industry, as are safe exposure limits. But the Wintek manager who decided to switch from alcohol to n-hexane for cleaning – apparently because it dried more quickly – did not assess the dangers. It was used without proper ventilation.

Asked if they knew what products they were working on, three of the affected Wintek employees said team leaders told them they were working for Apple. They instantly recognised pictures of an iPhone and said they were cleaning touch screens, adding that items for other brands were not affected because Apple had isolated its production line. A lawyer acting for 44 of the poisoning victims also said several had named Apple.

Bai Bing said she and her colleagues were cleaning components including Apple logos – the kind that appear at the bottom of desktop screens – when she fell ill.
