Stunningly preserved 700-year-old SHIP discovered beneath the streets of Tallinn was part of the Hanseatic. Referring to that outer shell as a 'display cover layer,' it adds that, 'to help mitigate the number of dents, scratches, or other imperfections in a display cover layer, the display cover layer may include a layer of self-healing material.'Īccording to Apple Insider, specifics about this miraculous self-healing material are pretty slim, other than it would employ 'a layer of elastomer.' Used in Apple Watches, Sapphire glass is thinner and more durable and scratch-resistant than the Gorilla Glass currently used in most high-end smartphones. The application for 'Electronic Devices With Flexible Display Cover Layers' says they 'may have an outermost layer formed from clear glass, transparent plastic, sapphire, or other transparent materials that serve as a protective layer for thin-film transistor circuitry and other display structures.' The proposed technology would use elastomer, a pliant material that returns to its original form when heated.Īpple's application suggests it could be used in phones, laptops, tablets, watches and other devices. 
In October it emerged the company patented its own self-healing screen technology.
The researchers are not the first or only people to try and fix the problem of smashed screens, with tech giant Apple also turned its expertise to the issue. The combination of these two layers has thus far only been tested in a laboratory but the researchers write that it could 'eventually be widely used in outdoor applications'. The top layer involves the linseed oil capsules whereas the bottom layer is the ubiquitous glass-like material used in phones, tablets and other gadgets called CPI.ĬPI is a transparent plastic which is strong, flexible and conducts electricity and is used not only in entertainment devices but also in solar panels. It is called a polymer bilayer film (PBF) which is a sandwich of two layers stuck together to form a single material. The study, published in the journal Composite Part B: Engineering, shows how the material was made and how effective it was. The process can take hours but is accelerated by warmer temperatures and UV light.ĭr Yong-Chae Jung, head of the center at Institute of Advanced Composites Materials at the Korea Institute of Science and Technology (KIST), led the study. Linseed oil is used to treat cricket bats and preserve art piece because it has no colour, is readily available and hardens a room temperature. Researchers tested how a material which combines existing plastic screens a layer of linseed oil microcapsules which release if cracks appear and harden in the fissures before hardening and repairing the damage automatically
