Apple could create a full-screen display for the
iPhone that doesn't have any notches or holes for cameras or other sensors, by moving the display panel to create a window whenever a photo is being taken.
One of the recognizable,
often copied, and complained about elements of the iPhone's design is the notch at the top of the display. Intended to allow the TrueDepth camera array to function, the size of the notch has been a problem for quite some time.
While Apple has been considering ways to
shrink down the notch for future devices, what it could ideally do is get rid of the notch altogether. However, doing that introduces other issues, chiefly about having a display and a camera sensor occupying the same space in a device.
