On paper, foldable smartphones seem the ideal idea: they allow consumers to have access to large screens that can be folded into formats that can be stored. But in reality, their designs present many challenges.
Detailed in a recently published patent, the Cupertino giant thinks that heat is the key to preventing damage to the screen. Thanks to a variety of sensors, the device in question will be able to follow the temperature of the billboard. If it's too cold, separate components will then heat a specific part of the screen. According to the patent, this should allow the flexible panel to easily adapt to its new position, thus reducing any potential deterioration.
The addition of a dedicated heating component to a device that can generate unnecessary clutter, Apple also suggested the implementation of an alternative solution. This would automatically increase the brightness of the display in the affected area to warm the panel. Once hot enough, the brightness will be automatically reduced.
