Samsung Flexible Devices







Samsung YOUM (The Flexible Phone)

In January 2013 Samsung officially launched their flexible OLED displays, calling them YOUM displays. YOUM panels are bendable - but it's likely that the first product to use those displays will actually be rigid. The display can be "curved" thought. A plastic based AMOLED will also be shatterproof, and also lighter and thinner compared to glass based OLEDs.






Is it really a surprise? Samsung's vice Chairman Kwon just revealed (source) that the company is getting a great amount of orders from electronics makers for it futuristic lineup of flexible organic light emitting diode (OLED) displays.





How are YOUM panels fabricated

According to reports, Samsung is still using LTPS for their plastic based panels. The production process is too hot for the plastic substrate (it will melt) and so the LTPS transistors are deposited on glass and the glass is later delaminated. The encapsulation technology is Vitex's multi-layer technology which is very slow (the panel has to enter the evaporation chamber 6 times). All this means that plastic displays will be more expensive than glass ones, at least until Samsung can use better production technologies.
