Of all the fundamental elements that make up an iPhone, the screen is the first that we always find and with which we identify the most. Therefore, keeping it in the best possible condition is essential for a good user experience. So much so that Apple plans to introduce a screen break detector in future foldable iPhones.

Anticipate damage to screens

If we add future screens or flexible screens to the screens we already know and use, it is even more judicious to add the detection of small breaks. Because? Because while it is obvious that significant damage will be visible without warning being required, small, almost imperceptible damage can reduce the resistance of the display and be the impact of more serious damage.

Faced with this situation, Apple is studying the possibility of including a rupture detector in future foldable iPhones, which we know from the patent entitled “Electronic device display with monitoring circuitry using a crack detection resistance” in which the company wishes to use the resistance. screen to measure its integrity.

Apple’s proposal is to add an additional section on the edges of the screen which, in addition to providing the connection with the device, would allow, among other things, breakage sensors. Thanks to deformation detection resistors, Apple was able to measure the stiffness of a screen. A mechanism that would be accompanied by a circuit capable of slightly heating the screen in certain areas to increase its malleability.

Timely notice would allow a repair to be arranged before the situation made it impossible to use the phone.

This same resistance measurement system could be extended to the entire edge of the screen to detect possible breaks, which would result in a high level of resistance. By measuring the distance from the point of collection of measurements to the point of maximum resistance, the system could determine the region of the screen affected.

By presenting this information to the user, we might be warned about the possibility of needing to repair or replace the screen without having to wait until the situation is unbearable. In a way, this technology reminds us of the battery service advisories of our Macs, we don’t have to wait for the battery to run out or the screen to break to schedule an appointment and repair. .

With these kinds of patents, we can clearly see the amount of technology and research and development behind small functions that, although they may seem far away now, we will take for granted in a few years. Ultimately, developing a foldable phone is more than adding a flexible screen to something that already exists, it’s thinking about lots of details and supporting technologies so that the user experience is the best it can be. .
