Samsung spills details on flexible AMOLED display

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.
