Presentation Summary

  • Recently, demanding issues evolved from flat panel displays (FPDs) system are concerned with development of high-performance and low cost thin-film transistors (TFTs) backplanes on desired substrates by easy-to-process yet highly integrated system.
  • In particular, even though active-matrix display with printable, novel semiconductors is attractive among FPDs, it is not realized because new organic semiconductors comparable to conventional a-Si TFT technologies are not developed.
  • For the production of well-defined and very uniform printed OTFT arrays, we have molecularly designed ambient processable functionalized conjugated copolymers with liquid-crystalline nature, enabling the high-performance OTFTs.
  • Our approaches enable the realization of polymer based flexible color-display, and offer a promising solution for the advance of future display.

Since its foundation, Samsung SDS has provided comprehensive ICT services and contributed to the growth of Samsung Group as a global company.
Samsung SDS has established 17 overseas offices in ten countries starting with SDS America in 1997, and has set up eight data centers in six countries since its first data center in Gwacheon, Korea in 1992.
Samsung SDS's business is organized according to the clients' business environments and needs.
It provides various ICT services such as business consulting,
network system integration (NSI), smart infrastructure engineering (SIE),
ICT outsourcing, business process outsourcing (BPO), ICT infra, and ICT solution.
 
In case of the composition of researchers at S.A.I.T, close to 40% hold Ph.D degree and in terms of the majors, 37% of researchers here hold electronics major and others spread across the board.
 
SAIT has 3 research centers, 1 technology center and 1 frontier lab .
 
Those are Future IT Research Center , Materials & Devices Research Center , Emerging Technology Research Center, Material Technology Center and Frontier Research Lab.
 
Last year we spent 300 million US dollars for research budget of 1300 employees.
