Believe it or not, the curved screen on the Samsung Galaxy Round smartphone isn’t just a marketing gimmick: The curvature actually causes a series of optical effects that result in improved contrast, color accuracy, readability, and overall image quality — especially under ambient light that usually makes smartphone screens almost unreadable, such as daylight or fluorescent office lighting.
This new information about curved displays comes from Raymond Soneira, who is one of the few authorities on display technology, image quality, and color calibration. From thestory on his site, it sounds like Samsung gave him a Galaxy Note 3, the Galaxy Round (which is the Note 3 but with a curved display), and a standalone, free-standing OLED display from the Round (which he could bend and flex to his heart’s content). While he hasn’t yet produced his usual slew of images and graphs, it’s clear that he’s very surprised by the massive gain in image quality afforded by the curved display.
