effects of curving large displays
This study investigated the benefits of a curved display compared with a flat display, and discovered the optimal radius of curvature for large-size curved television based on the subjective judgment on aesthetics and usability. The experimental results showed that the optimal radius of curvature varies depending on the display size and it increases as the size becomes larger. The curvature with a radius equal to 2000 mm is optimal for a 55-inch television, and the curvature with a radius range between 2000 mm to 3000 mm is appropriate for 65-inch and 75-inch televisions.
