Rumor: the Apple iPhone 7 might ditch in-cell touch panels to achieve thinner bezels
Digitimes, a Taiwanese publication with a mixed track record of reporting on upcoming products, recently quoted unnamed industry sources who claim that Apple will go back to the glass-on-glass touchscreen technology after relying on in-cell touch panels for about four consecutive years (counting here the upcoming iPhone 6S generation, which will most likely have an in-cell display panel). Starting with the iPhone 5, Apple switched from glass-on-glass touch panels to in-cell ones, a technology that is still used today on most modern flagships. In essence, the in-cell touch technology reduces the thickness of the display unit by integrating the touch panel in the display glass and has long been hailed as a way to make smartphones thinner without reducing the size of the battery.
As you could probably anticipate, Apple is definitely not going back to the old glass-on-glass technology with the 2016 iPhone 7. Instead, the report claims that the next-gen iPhone will make the switch to a new and improved version of the tech called ultra-thin glass-on-glass. The publication claims that Apple is facing some bottlenecks with in-touch panels, and that the technology is keeping the manufacturer from introducing new features and increasing the resolution. Furthermore, the in-cell touch tech is said to impose limitations on how thin the bezels can go, as these touch panels suffer from poor sensitivity right next to the edges.
As with all rumors, especially iPhone-centric ones, make sure to digest this info with a grain of salt. Even if Apple is truly planning to explore ultra-thin glass-on-glass touch panels, it's probably too early in the development cycle for the feature to be a lock for the upcoming iPhone 7. Thoughts?
