Photos are already trickling down of the flexible screen - unlike the previous 240x400 pixels attempts, this one sports a quite decent 480x800 resolution. Samsung says that ghosting is almost negligible on the flexible display with 0.4" (1cm) radius. The screen has a quick response time, low power consumption, and a thin profile. The usual rigid glass substrate is swapped for a special plastic one, with some of the technology coming from the Galaxy S's screen. The existing plastic substrates melt at 350-400 degrees, so no circuitry could be implemented in them.
Very exciting times, and we can't wait for Samsung to show the transparent and 3D displays as well, in a few days.
