Samsung have been demonstrating a 4-inch OLED panel that, at 0.05mm thick, is flexible enough to flutter in the breeze from a fan. Coined the “flapping display”, the OLED was manufactured in the normal way up until the point where it would be sealed in a glass substrate; instead, they used a new membrane sealing technology that both protects the display but leaves it flexible.
According to a Samsung representative, the 0.05mm thickness was a relatively arbitrary figure rather than the limits of the manufacturing process. “It is technically possible to make the panel thinner,” they explained, “however, it is difficult to further reduce the thicknesses of the flexible substrates and circuit components around it.”
The 480 x 272 resolution OLED has a 100,000:1 contrast ratio and 200cd/m2 luminance, and is capable of displaying 100-percent of the NTSC color range. Low-molecular organic EL materials were used, together with a low-temperature polysilicon TFT control circuit almost as thin as the overall display itself.

That’s very cool. I am interested in what type of products Samsung will offer with this new technology. Or maybe it’s just a boast like “Look what we can do.” Who knows. Very interesting none the less.
