Apple has reportedly acquired a patent for a display material that has self-healing properties. The material is believed to help the display recover from scratches as well as dents and might be a breakthrough technology as far as foldable smartphones go. Currently, Samsung has the largest share of foldable smartphones on the market worldwide and it employs a special material to protect the foldable display from external factors and enhance their durability.
According to a patently Apple report, the self-healing material layer may be included in the display cover layer of the folding iDevice. It might be made of elastomer. The layer may be present either in the flexible area of the cover display or on the full display. Deposit that self-healing may occur in the layer of self-healing material without prompting.
This might make the claim that if and when the cover layer is dented or scratched, the self-healing material included in the cover layer might correct the anomaly without a user''s external intervention. The report also states that self-healing may be initiated or expedited by externally applied heat, light, electric current, or other type of external stimulus.
If the cover layer of the above-mentioned iDevice is damaged by a scratch or a dent, it should be avoided. Heat may be used as a tool for self-healing, according to a predetermined schedule, or when the electronic device is charging.
The display cover layer may include a transparent dielectric layer with slits. In the flexible portion, these slits may assist in increasing the flexibility of the display cover layer.
