Folding iPhone Patent Application Shows How the Company Could Prevent Damage In Cold Weather

A new patent application from Apple, titled 'Electronic Devices with Flexible Displays,' describes how the company could prevent foldable smartphone displays from getting damaged in extreme temperatures. 'While at or in the region of typical temperatures hospitable to humans, folding systems may work fine, but adhesives and other elements used in a device's production may become more resistant to flexing at cold temperatures, which could cause unwanted wear or damage to the display if attempted in such conditions,' reports AppleInsider. 'To mitigate the cold temperature, Apple simply suggests there should be some way to warm up the area of the display panel where the bend takes place.' From the report: As part of Apple's solution, an onboard temperature sensor is used to determine how warm the device is, and whether or not there is any danger to allowing the screen to be flexed by the user. The warming process itself can be performed by a heating element located near to the section that bends the most, with heat conductors transferring the warmth to where it is required. A heating element may not be practical to add to such a device, which has led to Apple suggesting an alternative, namely using the heat generated by illuminating the screen. To do this, a screensaver could be used that concentrates most on the bent section, such as by making it brighter and lit up more than the rest of the screen.

As the heating process could take time to complete, Apple notes there is a danger of the display being flexed before it is safe to do so, something it has also considered. Aside from warning the user on an attempt to bend, Apple believes the use of a latching mechanism to keep the device closed while folded may be worth investigating, both as a mechanical latch and by the folded device being held shut by magnets. When the temperature of the area is relatively safe, the latching system can be disengaged and the user will be free to open the device once again. The patent application does not seem to answer the question of how to prevent the user from folding up an unfolded device, but it could be feasible some form of locking mechanism could be used when the smartphone is flat.
