Apple has actually filed a patent application for a self-healing display screen which it says is for a collapsible gadget with a display which covers the fold. The most apparent application of this would, of course, be for a foldable iPhone.
The concept would resolve one of the main problems found in early folding smartphones, such as the one which turned the unfortunate launch of Samsung’s Galaxy Fold into a PR catastrophe.
When you fold a screen onto itself, any dust or other debris that gets caught is most likely to damage the screen. It’s this issue the Apple creation aims to fix.
Displays are normally formed from rigid planar substrates. Although satisfactory in numerous situations, stiff display screens such as these may be hard to incorporate into specific devices, such as gadgets with bendable housings.
During operation of an electronic device, the screen cover layer for the electronic device might be scratched or dented. To improve the aesthetic appeals of the electronic device, it might be preferable for the presence of scratches and dents to be minimized. To assist reduce the variety of damages, scratches, or other flaws in a display cover layer, the screen cover layer might consist of a layer of self-healing material.
The patent application says that the suitable would be for the gadget to repair itself automatically, without the user requiring to do anything –– for example, while charging.
Self-healing may take place in the layer of self-healing material without triggering (e.g., when the self-healing coating is dented, the material of the finish may fill the damage even without external intervention). The self-healing may be initiated or expedited by externally applied heat, light, electric present, or other types of external stimulus.
When heat is utilized as a stimulus for the self-healing process, the display cover layer may include transparent conductors that form a heating layer in the display screen cover layer. The heating layer may be used to generate heat to promote self-healing. The heating layer might be utilized to generate heat in action to user input, according to an established schedule, or when the electronic gadget is charging.
Apple has previously proposed using heat to prevent damage occurring in the first place.
To assist in bending about the bend axis without damage when the display is cold, a part of the screen that overlaps the bend axis may be selectively warmed.
While Apple is rarely in any rush to bring new innovation to market, it does seem inescapable that we’ll see a folding iPhone eventually. Lots of Apple fans have actually said they’d purchase one, amongst them company co-founder Steve Wozniak.
