A glass keyboard could possibly be versatile, and now have a show beneath
Apple checked out utilizing single glass panels and touch-sensitive membranes when it was making an attempt to resolve its MacBook Professional butterfly keyboard issues, however the now newly-patented expertise additionally solves mud and put on points.
Attributable to their design, keyboards are in a position to be affected by components gumming up the mechanism, stopping the keys from easily reducing and elevating when pressed.
Whereas old style keyboards are much less inclined, the chiclet-style pocket book keyboards, like those used within the MacBook Professional lineup, could also be susceptible. They’ll simply be stopped from working effectively if mud, crumbs, or liquids enter below the keys and affect the mechanism.
This difficulty was one cause why Apple launched particularly its third-generation butterfly mechanism. That featured a silicone membrane used each to deflect mud and to quieten typing.
That was in 2018, however a 12 months earlier than, Apple had began submitting patent purposes for a unique answer. The applying and the design went via a number of revisions, and was truly granted in 2019.
However all these years later, Apple has been granted the identical patent once more. Patents get reapplied for, and sometimes re-approved, each time there may be some vital change, even when that change will not be instantly obvious on studying the documentation.
Extra vital than patent re-filing procedures, although, is that Apple did reapply. In some type, then, this little patent known as simply “Computer with Keyboard,” continues to be labored on by Apple.
It is now not going to be a repair for the butterfly keyboard, as that’s gone gone, and if not completely forgotten, at the least not missed. The butterfly points are actually thus far behind us that even a long-standing lawsuit about it has been settled.
But the rationale that the butterfly keyboard issues are behind Apple is that the corporate merely reverted to the older and far more fashionable scissor mechanism. It is such a considerably higher keyboard that really Apple could keep it up.
Nonetheless, reapplying for this patent is a sign that the corporate remains to be pursuing new keyboard designs — and the glass panel keyboard described on this patent does have potential benefits. That begins with the way it removes the necessity for unfastened or particular person keys, and for any type of common scissor or switching mechanism in any respect.
The patent actually describes how a keyboard could possibly be created with out shifting elements. In Apple’s proposal, a glass sheet could be used rather than the movable keys, with raised sections to indicate the place every key’s positioned.
Because the person presses down on one of many raised key sections, the keyboard detects the pressure enter to that, “key” and handles it within the typical manner inside an software.

Using raised keys would allow the proposed keyboard to supply a type of tactile suggestions to customers, permitting customers to know precisely the place their fingers are positioned in relation to the middle of every key. Whereas that is related in idea to a digital keyboard on a display screen, reminiscent of on a smartphone or pill, it’s a lot more durable to the touch sort on a digital keyboard as a result of not having the ability to contact the keys.
To supply a stage of springiness much like a standard key’s deflection, Apple suggests using a raised aspect wall across the raised key area, which could be configured to deform on enter. In some components, the keys can buckle, with a decrease layer together with components to push the important thing again into place and to detect every press.
Because the panel is glass, there may be then the additional benefit that Apple may embrace a show below it. That might enable for the important thing symbols to be outlined by a secondary show within the decrease part of the pocket book, making it comparatively easy to vary the keyboard structure to a unique language or an application-specific model.
Moreover, aspect sections could possibly be used as a type of trackpad alongside the keyboard aspect. That is one space that the patent’s illustrations completely ignore, and as an alternative present solely keys throughout the entire base of a MacBook Professional.
Discover no separate trackpad. As an alternative, the entire floor may act as one.
Nonetheless, the patent textual content makes a quick nod to trackpads. “[Substantially] the entire top case, from edge to edge, may define a touch-sensitive surface,” it says.
“In this way, touch or trackpad inputs, such as clicks, taps, gestures (e.g., swiping, pinching), and multi-touch inputs, may be detected on any portion of the top case,” it continues, “including on individual key regions within the keyboard region as well as on portions of the top case outside of the keyboard region.”
Whereas the thought can actually eradicate the potential for dirt-based keyboard mechanism failures, it additionally has a byproduct of doubtless making the keyboard even thinner, permitting for an even bigger battery to be included, or an total slimmer pocket book profile.
As Apple does file a lot of patent purposes on a weekly foundation, the publication of an thought will not be a assure the idea will seem in a future Apple product, however does counsel areas of Apple’s curiosity.
That is removed from the primary keyboard-based patent Apple has utilized for. Even again in March 2018, across the time it first filed this as a patent software, it alsoapplied for a “keyless keyboard.” That used the same secondary touchscreen show within the decrease part of a keyboard, however concentrated extra on using flat contact panels than variations with keyboard-shaped raised components.
In February of the identical 12 months, Apple was granted a patent for “Dual display equipment with enhanced visibility and suppressed reflections,” once more suggesting using a touch-enabled OLED show as a keyboard.
In August 2018, a trio of filings named “Device having integrated interface system” largely advised using plastic or glass to change the encompassing space of the MacBook keyboard, and even the keyboard itself, with touch-sensitive capabilities.
The patent is credited to a few inventors, together with the prolific Paul X. Wang. His earlier associated work features a patent software concerning using a glass keyboard for energy.
