Why the Galaxy Round’s curved display is worth exploring
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
Far from labeling Samsung’s curved display as a gimmick, DisplayMate president Raymond Soneira has written a detailed post which describes why the Galaxy Round’s form factor is worth exploring. Among other reasons, she cites:
Form Factor and Screen Privacy
…It is more comfortable to hold because the hand nicely fits the entire curved back instead of just holding it along the left and right edges. It also improves screen privacy because the curvature makes it harder for other people to see the screen.
Screen Readability in Ambient Light
…So if there is a way to reduce those screen reflections, it will not only improve the screen readability, image contrast, color accuracy, and overall picture quality, but also increase the running time on battery. One way is to reduce the screen Reflectance. It has been steadily coming down, and the Galaxy Note 3 and Galaxy Round have about 5 percent Reflectance, among lowest I have ever measured for mobile displays.
