Difference Between Original Vs. Fake LCD And Panel In Iphone

How to diagnose OEM (Original Equipment Manufacture) iPhone LCD and panel from high copy versions?
You might decided to change your phone’s LCD and you might not be able to diagnose OEM or Refurbished ones from high copy (when manufacturer release a product, it might have problems like hardware problem, or motherboard problem and … . in this situation, product returns to manufacturer, and they present its LCD and panel as Refurbished).
The easiest way to diagnose high copy LCD is to check it if there’s any tag on it! If there wasn’t any tag on LCD and panel, you can read this article to figure out how to diagnose OEM LCD from high copy versions.
1.    In OEM LCDs, there’s soap pad or small piece of sponge around the tape cables, and when you touch them you can feel how smooth they are. But in high copy versions, cables don’t have soap pad or they don’t have small piece of sponge and when you touch these cables, there are no smooth and soft spots. Also, high copy LCDs are less flexible than OEM LCDs.
 

2.    In iPhone OEM cables, there are Apple logo in one or two sides of cables, but you can see in high copy LCDs , Apple logo is been engraved with sharp object on cables.
 

3.    In high copy LCDs, the adhesive that keeps light sensor’s plastic is way too much weaker than OEM LCDs.

4.    In OEM LCDs, you see a white rectangular part in camera’s lens area which there’s no such a thing in high copy LCDs.

5.    The adhesive which is been used in OEM LCD to keep the guard of camera is so much stronger than the adhesive in high copy LCDs and in high copy versions the guard always fells off. Also in OEM LCDs which are black, there’s a blue loop to avoid and reflect the darkness so it could capture the pictures with good quality, there’s no such a thing on high copy LCDs.
 

6.    Soldering or adhesive which is done for sticking the backlight to LCD, is been done clearly in OEM, but not in high copy LCDs.
7.    OEM and high copy LCDs have serial number and logo, but there’s a difference: in OEM LCDs, serial number and logo are in smaller size and darker color and they have scratching mark, while in high copy LCDs, serial number and logo are in a bigger size and lighter color and they don’t have any scratching mark, and they can easily be gone by using alcohol pads!
 

 
8.    In OEM LCDs, on the top, in the left corner you can see a black matte tag which high copy LCDs don’t have this kind of tags, or if they have it, its not matte!

9.   OEM screens are Oleo. This means that they are resistive to fingerprint and make the screen anti-fingerprint (not 100%) and presents fluent touch and also it prevents scratches from appearing on the screen. Another feature of this OEM screen is feature of being waterproof. If a water drops on the screen, water drop moves without getting spread. But in high copy LCDs, water drop can spread easily.

10.    when you compare OEM LCDs with high copy LCDs, you can obviously see that OEM screen is much better with high quality, brightness and functions than high copy LCDs.


11.    whenever you pull your finger around the panel, you can feel how smooth it is, but if you do the same thing with high copy panel, you won’t feel it smooth.

12.    OEM LCD screens are matte than high copy LCDs.


 
13.    on OEM panel, there have to be a “V” sign on cables. You cant find this “V” sign on cables in high copy LCDs.


if you notice, there’s a “V” sign on the cable
 
If there’s V sign on digitizer cable and LCD cable, it means that digitizer and LCD are OEM.
if there isn’t V sign on Digitizer, but there is V sign on LCD cable, it means Digitizer is high copy, but LCD cable is OEM.
If none of the Digitizer and LCD cable don’t have V sign, it means they both are high copy and they are not OEM.
at the end, I should remind you that this article was about iPhone's LCD and touch. I hope after reading this, you could be able to diagnose OEM LCD and panel from high copy versions.😉💚
