Firstly, let's run a cosmetic inspection of the screen. We can see that the iPhone 12 has a narrower bezel than the iPhone 11 Pro, so the iPhone 12 bezel may be a little easier to disassemble.
In addition to that, the iPhone 12 bezel doesn’t wrap around the glass lens anymore. Therefore, the material requirements for the bezel adhesive will be relatively high to prevent the adhesive from falling off. To dig deeper, we will refurbish the iPhone 12 screen.
Remove the ear speaker flex cable first. Since the ear speaker flex cable is very easy to damage, please be noted that we need to heat the screen before removing it.
Besides, the iPhone 12 ear speaker sensor ring is integrated into the bezel.
As the ear speaker flex cable part has more adhesive, we can dip more adhesive remover to make it loose.
Hold the two corners of the bezel in both hands, and detach the bezel slowly with caution.
Our original thought was to separate the bezel in a complete manner and then reuse it. But now the bezel is broken here. So please notice that this part of the bezel is made of plastic material, which is extremely easy to break. If you want to separate the bezel completely, you need to pay extra attention.
In order not to induce damage, we use a thin film to remove the flex cable part.
Remove the bezel and it can be seen that the 3M adhesive used in the bezel flex cable part is no longer the cold adhesive. The 3M adhesive makes the bezel relatively easy to remove.
Remove excess adhesive on the ear speaker flex cable part.
Start separating the OLED along the bottom layer of the glass lens with Cutting Wire.
Through our observation, we found that the touch panel of the iPhone 12 screen is better than that of the iPhone 11 Pro, which is not easy to damage. To put it specifically, the touch panel of the iPhone 12 is thicker and the cut lines are clearer and wider.
Connect the OLED and ear speaker flex cable. The display and touch function works well.
A point worth mentioning is that not connecting the ear speaker flex cable will lead to the absence of light-sensing. The screen will be too dark to be tested.
