I think you cannot buy all original LCD panel directly from those real manufacturers such as LG/sharp/Toshiba/etc. these LCD panel manufacturers were authorized by apple, that apple used them to install on their iPhone 4/4s/5/5g/5c/5s/6/6s. They would not sell these LCD panel directly to wholesalers or distributors in the market, because this way will violate the agreement with apple signed which cannot sell these LCD display assembly to third party without permission, even if they can sell those lcd panel to others, may I ask who is able to purchase 1000000pcs at a time? If you are not larger mobile phone manufacturer, since this is MOQ for them to sell.
However why are there still big quantity flows into the market?
Who can buy it unless apple or other cell phone manufacturers?
I think there is reason that should catch your attention! Apple often authorized them to produce larger amount of LCD panel display assembly for their new iPhone model, apple QC team go to their factory for regular inspection on lcd panel, as we know, apple have very rigid standard on their quality, when their QC found defective rate exceeded 97~98% during the inspection, batch bulk must be returned back and lcd panel manufacturers must re-produce again to supplement those defective items.
The question is manufacturers must have to face high loss for that defective batch bulk item which is returned back, but they also did not want to destroy and ruin them since they invested too much money on producing those panels, so they found a market channels to dump these LCD panel via someone be called “parallel traders”. Most demand market on these LCD panels is just in Shenzhen and Guangzhou China, some of them use to OEM or sell, so you can see why so many wholesalers shout out to you that they have high quality or lower price iPhone LCD panel display or send you email endless every night through group sending software.
Another question is that LCD panel with defective rate is really poor quality or not? In fact, those defective rates is only lower than good rate of apple set up, at least 90% of those LCD panels are still good quality.
Anyway, i have also good channels to help you if you are interested in it, but I am willing to provide you with useful information what you need to know.
