IFixit disassembled display iPhone 6s to look at implementation 3D Touch

Soon after the release of iPhone 6s and iPhone 6s Plus, iFixit craftsmen were able to disassemble them and examine the changes made by Apple to the hardware of the devices.

Parsing iPhone 6s

It turned out that there are a lot of interesting things inside, and recently they have done another analysis iPhone 6s, this time completely dedicated to the phone display. Of particular interest here, of course, is the technology 3D Touch implemented in the display of the new iPhone.

Disassembly was carried out in 12 steps. It was decided not to set a repairability rating, as iFixit usually does, motivated by this: “This disassembly will not include a repairability rating, since the process of parsing and assembling the screen is better left to professionals with their special (and cool) tools.” The last, thirteenth, step demonstrates eight different layers from which Apple assembles a solid display.

Here's what we found. Disassembly results showed that the sensor 3D Touch is installed in the back of the display panel, and therefore, according to them, it is quite simple to separate it from the backlight, digitizer and the display itself. What's more, the Home button cable has been replaced with a track that runs along the touchpad 3D Touch, so you don't have to deal with the cable when fixing the screen.

Well, about the new touch panel:

“The touchpad is a grid of rectangular capacitor boards connected to the power controller by thin strips. These boards would be too large for a touch sensor, but their job is not to track your finger on the screen, as the digitizer is doing now. These sensors are designed to measure the distance to the finger, or, equivalently, the force of pressure on the screen. ”

Apple shoved a bunch of technologically advanced pieces into the display of the new iPhone 6s and 6s Plus, and the teardown from iFixit sheds light on them.
