Samsung announced its Galaxy S6 smartphone last month, including an Edge variant that curves the screen over the sides of the handset. The Edge uses Samsung's third-generation flexible display, and the firm expects the underlying technology to eventually power foldable and rollable displays. Although the current tech is merely bendable, we now know a little bit more about how it works.
Instead of arranging display elements on rigid glass, Samsung deposits them on a polyimide plastic substrate. At under a millimeter thick, this substrate is purportedly half the thickness of the material used in conventional mobile displays. Samsung claims the resulting AMOLED is "potentially more bendable than a human hair," though it doesn't detail the limits of the bending radius or how well the display holds up to repeated bending stress.
The display spreads 1440x2560 pixels over a 5.1" diagonal, producing a razor-sharp pixel density of 577 PPI. Samsung claims "almost 100%" coverage of the Adobe RGB spectrum, a wider gamut than the sRGB color space. More impressively, perhaps, the firm pegs the display's response time at only 0.01 milliseconds. That's much faster than the 8-ms response of typical mobile LCDs, Samsung says, and it puts even the best desktop monitors to shame.
