Ever wished for a bit more privacy while using your smartphone? Well, it looks like Apple is working on making that happen with some innovative screen technology. Recent reports reveal two granted patents shedding light on the tech giant’s efforts to enhance iPhone screen privacy.
The two options that Apple is researching are using a privacy film layer over the screen and displays with adjustable angles of view.
The first patent, “Privacy films for curved displays,” explores the possibility of adding a privacy film layer to the screen. This film acts like a polarizing filter, allowing light to emit in only one direction. While similar film layers exist in the market, they prove to be somewhat limited as visibility is restricted to a single point. This can pose challenges not only for onlookers but also for the device user.
While anyone trying to view the screen from an angle will see a blurry or completely obscured image, this film layer does not provide complete privacy, as anyone standing directly behind the user will still be able to see the screen.
Moving on to the second patent, “Displays with adjustable angles of view,” Apple takes a subtler approach by proposing alterations to the viewing angle of the display.
According to the patent, in a private viewing mode, the control circuitry applies a current to electrodes, causing the electrochromic material to become more opaque, thereby limiting the display’s angle of view.
Unlike the first approach with an external film layer, this second method integrates privacy features directly into the display itself. These patents hint at Apple’s ongoing efforts to enhance user privacy without compromising display quality. As technology continues to evolve, it will be interesting to see how these innovations shape the future of smartphone displays.
