Display expert Raymond M. Soneira:
Introducing a slightly curved cylindrically concave screen is a
very important and major innovation in Smartphone display
technology — very far from being a marketing gimmick as has been
widely reported. The Galaxy Round screen curvature is very subtle,
just 0.10 inches away from flat, which is similar to the slight
curvature in a handheld magnifying mirror. But that small
curvature is the key to a series of optical effects that result in
significantly reducing interference from reflected ambient light
by a large factor. It substantially improves screen readability,
image contrast, color accuracy, and overall picture quality, but
can also increase the running time on battery because the screen
brightness and display power can be lowered due to the reduced
light interference from ambient light reflections.
But that’s for a concave display. Bloomberg’s report regarding Apple’s supposedly forthcoming displays describes “larger displays with glass that curves downward at the edges” — downward sounds like convex, not concave. It’s possible that Bloomberg’s source is describing a design where the display is flat but the glass surface above the display tapers at the edge of the device.
