Popular teardown site iFixit decided to take a closer peak at the iPhone 6s by breaking down the device's display assembly and revealing each of the layers.

Apple touts the iPhone 6s as being built with the 3D Touch technology which allows the device to sense deeply the way its user presses the display. This way, the user can do all essential phone activities quicker and simpler.

"This time, we're breaking down the Retina HD display assembly layer-by-layer to give you the skinny on what makes this year's hardware so unique," said iFixit.

The teardown begins with some added descriptions on the iPhone 6s display. According to the site, the device's 3D Touch feature is facilitated by the use of a capacitive sensor layer. The glass cover is made by dual ion-exchange which is responsible in making it pliable. The phone's Retina HD display, which measures 4.7 inches and has a resolution of 1334 by 750 pixels, also comes with an integrated touch digitizer.

The first thing that has to be removed is the phone's plastic mounting frame since this is the part that contains the clips which make the display secured to the phone's body. Next, the plastic mounting frame is removed in one solid piece by simply cutting around the perimeter of its assembly. Apart from cutting, some level of heat was also applied, the purpose of which is perhaps to "melt down" the new adhesive gasket which secures the display to the body.

In the third step, the mounting frame from the front panel was successfully removed.

All in all, the teardown involved 13 steps which revealed the eight layers found in the display of the iPhone 6s. It turns out that these eight layers include a plastic mounting frame, backlight, metal-backed layer (mylar sheet), second layer of sensors (found underneath the mylar sheet), LCD, front glass, polarizing film, and the edge-lit LED backlight.

According to iFixit, the mylar sheet found in this year's iPhone iteration is now built to work with two purposes in mind. The new purpose is "to obscure the 3D Touch sensors from view" while the old purpose is "to reflect diffused light outward instead of wasting light on the internals of the iPhone."
