Apple does not want its users to use iPhones with broken screens

In the future, iPhones may come with a system that notifies users of a damaged screen using a resistor to detect fractures, in a patent granted to the Cupertino-based technology giant by the United States Patent and Trademark Office, The company highlights how it wants to introduce a mechanism that will solve the problem for unnoticed cracks on the iPhone screen or restrict those who choose to continue using an iPhone with a broken screen.

And according to a report by Apple Insider, the device's patented electronic display with a control circuit uses a break-detection resistor Apple wants to add a section called a "curved tail portion" to the edge of the screen, as this section will then be used to interface with the phone system. To notify users about screen cracking.

How it works?

Apple wants to pair a strain-sensing resistor with a temperature-compensating resistor to create metal zigzag traces, and the patent says that strain measurements can be obtained by subtracting the temperature-compensating resistor from the pressure-sensing resistor, essentially meaning that a warm display may be more flexible and therefore more prone to cracking than the cold version.

The patent also mentions a crack detection line consisting of a ring-shaped signal path with two parallel metals running along the perimeter of the active region of the screen. Which indicates cracks in the line and in structures elsewhere on the screen.

In simple words, the device will be able to check the line resistance to detect fractures to see if the phone has a crack on the screen or not.
