Several situations that need to use this cable

There are two ways to install the fingerprint cable, one is to install in the backlight, the other is to install outside the backlight.

To install it in the backlight, we need to heat the screen first, using a screen splitter or a hair dryer.Below we will use the screen splitter to demonstrate how to install the fingerprint cable into the screen backlight.


① Set the temperature of the screen splitter to 60℃.


② After the backlight is heated (about 30s), we only remove the backlight iron sheet with the 3D touch sensor. Note that if the remaining fingerprint cable is not conducive to our operation, we can cut it first.

③ Remove the 3D touch sensor cable.

④ Tear off the double-sided adhesive protection of the fingerprint cable and then stick it back to the backlit iron sheet.

⑤ Reinstall it back on the screen, install and test.

2. The method of installing the fingerprint cable outside the backlight


① Cut off the original fingerprint cable on the screen.


② Glue the fingerprint cable to the display cable of the screen.
