Definition of “Flexible” Display
 Flat – made on plastic or other non-glass substrates for the purpose of
lightness/ruggedness
 Conformable – bent once in application
 Bendable/Foldable – intended to be bent or flexed repeatedly during use
 Rollable – intended to be rolled and unrolled during use

Conclusion
• Explore emerging market
– Light-weight, thin, unbreakable, and flexible features of display are
expected to lead to a new era for existing ICT product design and emerging
applications such as education.
• Driving new business
– Korean companies dedicate on commercialization and mass production of
flexible display. Taiwan has accumulated enough capabilities on display
industry over the past years and is suitable to get into the new business of
flexible display.
