Samsung's Flexible Display Hits a Technical Snag

Samsung Display, which is pushing for the commercialization of its flexible display within this year, has caught on in a technical snag
near to a plastic substrate, ie encapsulation technology, Samsung Display has improved its Technology, which had been regarded as the biggest technological obstacle, -commercialization degree.
It was said that Samsung Display was turning its eyes to other technologies since the adoption of Vitex System's encapsulation technology come, it is having difficulty upgrading its encapsulation technology, the patent on which Samsung Display purchased from U.S. company Vitex System at the end of 2011.
Since excessively lengthens the MANUFACTURING time. OLEDs are vulnerable to moisture and Oxygen, encapsulation processes are crucial to the commercialization of flexible displays,
Samsung Display is reportedly reviewing various encapsulation technologies that can replace the encapsulation technology developed by Vitex System
Samsung Display said " As we have accumulated expertise in this field, progress is being made ​​in substrates as well as encapsulation technology. We have developed a new technology than can shorten the encapsulation process to less than 2 minutes by using the Vitex System-developed encapsulation technology. " Samsung flexible commercialization of technologies bag, a problem this year to promote the commercialization of flexible displays Samsung Display bags ran into technical difficulties. 15 According to industry sources, the Samsung display `Vitex` bag closer to commercialization, to the level of olrateuna plastic substrate process technology, until now, has hit the biggest technical barriers, to buy patents and confidence seemed encapsulation struggling. expected, the processing time is too long, if you apply a technique recently turned to other technologies, organic light-emitting diode (OLED) is susceptible to moisture and oxygen, which prevents this bag Encapsulation process is essential. Bought a bag of glass and aluminum and other metal bag is generally difficult to apply to the display of a flexible plastic substrate, the Samsung display, the end of 2011, the last bag technology-related patents from the United States Vitex. The Vitex technical stacked alternating layers of organics • Mineral water and oxygen injection to block the way. Looking to amass multiple layers, typically 7-8 layers to build the process is time-consuming. Suffer from tens of minutes saw the encapsulation process may be over, usually 2 to 3 minutes per sheet glass, has become the bottleneck to improve productivity. But prototyping technology known that the limit for the mass production process the Samsung display a variety of encapsulation technologies are introduced to replace the Vitex. Way once more, using thick-film hybrid approach or the use of certain substances sealed through the glass membrane and moisture penetration has emerged as an alternative, rather than the biggest worry was the plastic substrate process technology development has been proceeding smoothly. Mounted even hundreds of high-temperature process for forming a thin film transistor (TFT), but can not stand the plastic. After the TFT process on a glass substrate coated with polyimide (PI) and instead of glass as a way to pull off the plastic substrate. Difficult to remove the glass, and to maintain the uniformity of the substrate after removing the difficult suffered headaches. But is said to be the know-how accumulated over a long period of time, while preparing for the mass production of side display Samsung "As we build up know-how as well as the substrate, the technical progress in the bag has been Vitex also can be reduced to a one-component technology okmun@etnews.com munbogyeong reporter has developed, "he said.
