How to identify from appearance for INCELL, OLED(China), newOLED(China) and OEM.
Thickness of mobile phone screen after installation:
INCELL>Original Thickness.(thicker 0.5-1.0mm)

OLED(China)=newOLED(China)>Original Thickness.(thicker 0.3-0.8mm)

OEM=Original Thickness.

The width of the black border on the side of the phone screen:
INCELL>OLED(China)=newOLED(China)=OEM(Ori)---(0.3mm-0.6mm)
The width of the black border at the bottom of the phone screen:
INCELL>OLED(China)>newOLED(China)=OEM(Ori)---(0.5mm-0.8mm)

Maximum Brightness:  INCELL:720-750 OLED(China):780-810 OEM(Original):820-850

If there are repair buyers and wholesale buyers who need to identify different types of screens through technology and display effects, please contact customer service directly. We will explain all relevant technical issues to you. (Due to the technical composition of the PINZHENG factory's products, it is not possible to fully disclose them)

About INCELL/OLED(China)/newOLED(China)(Upgraded)/AMOLED/OEM

Incell

Advantages: the price is very favorable, the quality is stable.

Disadvantages: The brightness and resolution are 70% of the original, the power consumption is high, the black borders around are thicker than the original, the screen thickness is thicker than the original, and the black interface displays dark gray, but it can meet daily use.

OLED(China)

Advantages: The price is moderate, with a resolution and brightness of about 85% of the original, making it the most cost-effective type.

Disadvantages: The black border at the bottom is wider than the original. Cannot display a pure black interface. The black interface will display a gray color. The screen thickness is only slightly thicker than the original.Power consumption higher than the original.

OEM

Advantages: All products are made of original materials.

Note: This product is not assembled by Apple, but by Pinzheng using original materials.

About 3D Touch and Face ID: 
All models: All products have this feature

All Support Face ID, Unless The Camera Chip Damaged Or Replaced.

iOS 18.1 can directly support True Tone.

The following two methods can solve the problem of the phone not being recognized, even if iOS ≤ 18.1, it can still have True Tone function.
Method 1: Transplant IC chips
All models can be ported with IC chips to achieve True Tone function and automatic brightness adjustment.
Method 2: Copy the IC chip code
X-XR-XS-XSMAX: IC-chip no encryption system, 100% probability, it can achieve True Tone function and automatic brightness adjustment by copying the IC chip code.
11-11pro-11promax-12-12pro-12pro-12promax-12mini: 

The IC chip has an independent encryption system, and there is a 50% chance that the True Tone function and automatic brightness adjustment can be achieved by successfully copying the IC chip code, and if the copy is unsuccessful, the IC chip can only be transplanted.
13,14,15 series : there is a two-layer encryption system, and True Tone and automatic brightness adjustment can only be achieved by porting the IC chip.

Due to system encryption issues, if the handset cable has been replaced, but the handset sensor chip has not been transplanted at the same time, the above functions cannot be realized.
(incell: does not support chip transplantation, OLED/AMOLED/OEM: supports chip transplantation)
