Apple TV could let you view two shows on one screen — here’s how
Apple tree Television receiver could allow you view ii shows on one screen — hither'due south how
A contempo Apple patent awarding, published last Thursday, details a new multi-view screen engineering that could let multiple viewers watch different content simultaneously on a unmarried screen. This could pave the fashion for monitors and displays being used past several people at once.
Patent application 20210099692 was spotted by PatentlyApple this week, and it's a fascinating glimpse into possible future features or products out of Cupertino, with applications beyond laptops, tablets, monitors and fifty-fifty TVs.

Titled "Method and device for operating a lenticular display," Apple tree's patent application shows a lenticular layer paired with a video brandish to show "unlike content at unlike angles."
While most proof-of-concepts for this technique are built around showing one user a pair of images, or two users dissimilar images, Apple's patent awarding suggests that it can serve more than than two users, claiming "whatsoever number of users may be nowadays in the example operating surround and take different content presented".
Lenticular what now?
Lenticular displays apply a serial of lenses manufactured into a single transparent canvas, with individual lenticules that nowadays a different portion of an image based on the position of the viewer. Traditionally, these are paired with prints or displays that slice an prototype into fine vertical strips. By alternating the strips from i image to another, changing the angle of view lets the viewer encounter images in rapid succession. Put it on a baseball card or a Happy Meal toy, and you tin utilize two or three of these segmented images to create the illusion of move. Sometimes that means a moving cartoon grapheme, other times, it'south to create the illusion of an object in 3D.
Lenticular displays do something similar by aligning the lenticules with individual scan lines in a display. If ane ready of browse lines shows one video, and the other set shows something different, you lot can use a unmarried display to testify different videos to different users at the same time.
Apple tree's proposed multi-view screen would employ more than than a simple lenticular layer. Information technology would incorporate the lens technology alongside cameras for user position tracking. Liquid crystal layers could guide imagery to unlike specified viewing angles and color filters would proceed the filtered images looking articulate and undistorted.
Where would multi-view tech show upwards?
Apple'south patent application provides examples of using the technology to bear witness dissimilar shows with unlike content ratings to different family members, letting the grown-ups watch TV-MA rated shows while the kids watch something more age-appropriate. One interesting tidbit suggests showing an edited version of the same prove to the younger viewers, letting the entire family lookout man the same program, but with age-appropriate edits for the different family members who might be watching.
It'southward not the first time lenticular displays have been used in consumer tech. The Nintendo 3DS uses ane to provide spectacles-free 3D, providing a slightly different motion-picture show for the right and left heart of the user to create the illusion of depth. Other attempts to use like lenticular engineering science have tried to scale upward the glasses-gratuitous 3D concept to laptops and TVs, but these products have never caught on.
It'due south non even the first time that Apple tree has toyed with the idea of using lenticular screens for its displays. The visitor filed an application dorsum in 2016 that used the same technology as a privacy tool, limiting screen visibility to the user and restricting and off-angle viewing that could be used to sneak a peek at sensitive or private information.
