Apple is researching increasing the nano-texture glass that it launched on the Professional Show XDR, to carry the expertise’s advantage of higher anti-reflective properties to the iPhone or iPad
“Antireflective Therapy for Textured Enclosure Parts,” is a
“>newly-revealed
patent utility that’s involved with bringing this expertise to extra units. As ever, Apple desires to cowl itself for all prospects, so these units embrace “a cell phone, a pocket book computing gadget (e.g., a pocket book), a pill computing gadget (e.g., a pill), a transportable media participant, a wearable gadget, or one other sort of moveable digital gadget.”
And simply to make certain, a tool with one among these nano-texture screens “may additionally be a desktop pc system, pc element, enter gadget, equipment, or just about some other sort of digital product or gadget element.”
Nonetheless, the drawings consider an iPad-like gadget, whereas the remainder of the textual content avoids being particular however does point out telephones a few instances. Regardless of the gadget, Apple is evident that there needs to be a show that exhibits “graphical outputs which are seen by means of the textured area of the glass member.”

Element from the patent displaying nano-texture glass being utilized in a transportable gadget
This “textured area” is specified as being “substrate floor, a set of protrusions extending outwardly from the substrate floor, every protrusion of the set of protrusions having a width higher than or equal to about 750 nm and fewer than about 10 microns.” It goes into extra element about these protrusions, nevertheless it’s finally describing strategies of etching onto the glass.
“[For instance, chemical] etching strategies for glass members might contain utilizing an acid to take away parts of the glass member,” continues Apple. “Etching strategies additionally embrace reactive ion etching, which [may be] mixed with lithography.
In every proposed system, the tip result’s a tool that has a single piece of glass which has this etched texture. It is this which makes nano-texture work effectively at decreasing reflectivity, because it prevents mild being mirrored proper again on the person.
There are vital engineering challenges to doing so, nevertheless. Partially because of extra floor space, even on the “nano” degree, the gadget might lend itself to scratching extra simply. Apple minimizes this by requiring and together with a particular material for cleansing, and it is not clear how it will additional shield a tool like an iPhone that’s supposed to be routinely pocketed by customers, typically by accident adjoining to onerous particles like sand within the pocket or cash, keys, and different accoutrements of recent life close by.
The patent utility is credited to a few inventors, Joseph C. Poole, Matthew S. Rogers, and Naoto Matsuyuki. The latter two have beforehand labored on a patent utility relating to a potential glass keyboard.
