Having already completed the iPhone 6s teardown on launch day, the folks over at iFixit have once again dissected the device’s display in order to find out exactly how Apple implemented the 3D Touch feature, and what will that do to the screen repair procedure. “To satisfy our curiosity, we cut, pried, hot-wired, and scraped at the display assembly of our brand-new iPhone 6s, and examined the entrails for signs and portents”.

And here’s what the teardown experts found out:

  • The 3D Touch sensor assembly lives on the very back of the display panel, and is fairly easily separated from the backlight, display, and digitizer glass.
  • The home button cable has been replaced by traces along the side of the 3D Touch sensor panel, eliminating the need to transfer the cable for certain display repairs.
  • The sensor panel is a grid of rectangular capacitor plates, connected to the controller IC by very tiny traces. These plates would be huge for a touch sensor—luckily their job isn’t to pinpoint your fingertip on the screen, as the in-screen digitizer will still handle that. These sensors measure the distance to your finger, equating to the force of a press through pliable glass.
