Samsung shows new 4" flexible AMOLED that is so thin (0.05mm) it 'flaps' in the wind

Samsung has shown their new 4" Flexible AMOLED (480x272, contrast 100,000:1, 200cd/m2 luminence). It is very thin - 0.05mm in fact - that it 'flaps' in the wind (Samsung placed it near a fan...).

Samsung calls it the 'flapping display'. They claim they can actually make it thinner, but it's a bit difficult.

To achieve this thickness, Samsung etched an OLED panel that uses a normal glass substrate. The drive circuit was formed by low-temperature polysilicon TFTs. Also, low-molecular organic EL materials were employed.

The panel was not sealed by a glass substrate but by membrane sealing technology using a sputtering method. That's why the 0.05mm thickness is almost the thickness of the drive circuit board.
