, fingerprints on the screen never seem to go away.
In its latest patent filing, Apple details another solution to battle greasy fingers. The solution involves applying a coating of an oil resistant material that would bond with the screen in a special environment.
are prone to gradual wear and tear due to humidity and heat.
The method that Apple uses currently to apply the coating is placing a bunch of pellets of coating in a chamber with the glass then superheating the pellets, which vaporize and coat the glass.
hopes to improve upon the shortcomings of this method by using a different technique of applying the oleophobic substance on the screen.
The oleophobic ingredient could be provided as part of a raw liquid material in one or more concentrations. To avoid adverse reactions due to exposure to air, heat, or humidity, the raw liquid material can be placed in a bottle purged with an inert gas during the manufacturing process.
The bottle could be placed in a liquid supply system having a mechanism for controlling the amount of raw liquid material that passes through the liquid supply system. Upon reaching the vaporizing unit, the liquid could be vaporized and the oleophobic ingredient within the liquid can then be deposited on the electronic device component surface. As the liquid supply is drained from the bottle, additional inert gas is supplied in its place to further prevent contamination.
The patent application was filed in February this year, so lets hope the
 display comes with the improved oil resistant coating.
