Our phone lines and emails have been going crazy in the past
couple days. Many of you in the repair community may have heard about the new cheaper screens selling between
$40-$60 wholesale price for the iPhone 6. We’ve heard it all. Customers calling
saying our prices are expensive compared to other wholesalers. One problem, there
is a major issue that has not been addressed. Those are copy screens and right
now there are a few different screens out in the market, they are TM, LT, JDF,
Copy TM, and of course OEM. Here are the current known issues with the different screens currently
being supplied that will hopefully make you think twice before getting those
cheaper screens. Especially with iOS 9.3 now out.

What is a TM Screen?
OEM iPhone manufacturers use In-cell
technology to make the LCD screens, while 3rd party manufacturers
have to choose other economic methods due to cost and risk. TM manufacturer
adopt the G+F structure, which build the senor part on a film layer then assemble
the film layer with the glass lens to be a whole digitizer touch screen. This is the better out of LT and JDF.
What is a LT Screen?
LT manufacturer use the OGStechnology to make the digitizer touch screen. The touch sensor is
embedded on the glass lens and the cover lens is made very thin to make sure
the digitizer work as good as possible to receive the command from fingers. The
LT LCD screen is so thin that we can see the dots and diamond textures beneath
the cover lens. The thin screen makes the glass very fragile
What is a JDF Screen?
JDF manufacturer use the G+G structure
for its LCDs. G+G means glass plus glass. The digitizer touch sensor is made on
a glass lens then the glass assembled with the cover lens as a whole digitizer
touch screen assembly. Apparently, this kind of structure will increase the
thickness of the digitizer touch screen, but it makes it possible that when the
screen break, the digitizer screen works as usual. In the opposite, once the LT
OGS LCD screen breaks, the whole LCD screen assembly goes bad, and it can't be
repaired except replacing the whole part. By the way, the G+F and G+G structures
both help prevent this bad situation.

In Summary:
TM screens are considered the best aftermarket screens out on the
market and closest thing to OEM. Although they are not the cheapest they do
work the best and are the best alternative to OEM. However currently the TM
name is being slaughtered by the copy TM making its circulation in the market.
How can you get TM screens? That depends on how much you trust your supplier. You
must know that price difference between OEM and TM and sometimes is not much
depending on the supply.
Copy TM screens are being sold for half of the current price of TM the
main problem is the copy TM screens do not work on iOS 9.3 for an unknown
issue. All we know is that if a customer tries upgrading or restoring their
device on iOS 9.3 phone will not work at all. However, these are reports from
the market, but lets not forget the 30% defect rate either. These copy screens
are selling for the cheapest and will not be remanufactured once stock is out.
LT screens are fragile which means a simple drop will most likely
crack the screen. Not to mention they take huge amount of power from the device
resulting in a shorter battery life and could potentially short the customers
iPhone®. On the bright side these screens have been discontinued from the
market due to these issues, but there are still screens in circulation from Chinese
suppliers who are trying to get rid of the stock.
JDF screens are not fragile like LT, but they still absorb huge
amounts of energy from the device and like the LT it does drain the battery a
lot faster and consumers will come back to complain. Due to the high energy
consumption the screens have been linked to cause a weaker signal output to the
devices, specifically RF. I would like to note these are only about 50% of the
screens with that issue and because of that reason these screens are still
making their way around the market. They are compatible with iOS 9.3 but
overall screen defect rate is almost 40%.
