Apple bags patent for foldable self-healing display: Report


Apple has reportedly secured a patent for a display material that has self-healing properties. It can be used in future foldable smartphones from the iPhone-maker. This material is reported to help the display recover from scratches as well as dents and could be a key technology as far as foldable smartphones go. Currently, Samsung has a major share of foldable smartphones in the market globally and it uses a special material to protect the foldable display from external factors and make them durable.

according to a report good Patented by Apple, the display cover layer of the folding iDevice may incorporate a self-healing material layer. It can be made from elastomer. The layer can be present either in the flexible area of ​​the cover display or on the full display. The report also mentioned that self-healing can occur without any indication in the layer of self-healing material.

This could mean that if and when the cover layer is scratched or scratched, the self-healing material included in the cover layer can correct the discrepancy without outside intervention from the user. The report also states that “self-healing may be initiated or accelerated by externally applied heat, light, electric current, or other types of external stimuli.”

For example, let us imagine a situation when the cover layer of the above mentioned iDevice gets damaged by a scratch or dent. To provide a smooth tactile experience, the cover layer should be without any discrepancies. The self-healing material layer can use heat as a stimulus for the self-healing process. “The heating layer can be used to generate heat in response to user input, according to a predetermined schedule, or while the electronic device is charging,” the report said.

It is also mentioned that the display cover layer may also include a transparent dielectric layer with slits. Slits can be filled with index-matching material. In the flexible part, these slits can help increase the flexibility of the display cover layer.
