According to reports, Apple has obtained a patent for a self-healing display material. It might be employed in the iPhone maker's future foldable smartphone. This substance is said to help the display recover from scratches and dents, and it might be a game changer in the world of foldable smartphones. Samsung now holds the lion's share of foldable smartphones on the market, and it employs a unique material to protect the foldable display from external elements and ensure longevity.
According to Patently Apple, the self-healing material layer may be integrated in the folding iDevice's display cover layer. Elastomer might be used to make it. The layer might appear on the cover display's flexible section or on the entire panel. The paper also indicates that self-healing may occur without prompting in the layer of self-healing material.
This might imply that if and when the cover layer is dented or damaged, the self-healing material included in the cover layer could repair the defect without the need for human interaction. According to the paper, "self-healing may be triggered or accelerated by externally provided heat, light, electric current, or other sort of external stimulation."
Assume, for example, that the cover layer of the aforementioned iDevice is damaged by a scratch or dent. The cover layer should be free of flaws in order to provide a smooth touch experience. Heat may be used as a stimulus for the self-healing process by the layer of self-healing material. According to the paper, "the heating layer may be employed to create heat in response to human input, according to a predefined schedule, or when the electronic device is charging."
A translucent dielectric layer with slits has also been described as part of the display cover layer. The slits can be filled with a material that matches the index. These slits in the flexible section may aid in enhancing the flexibility of the display cover layer.
