Presentation Summary

TFT- LCD processes need to be changed to low cost technologies reducing photolithography and vacuum processes.
It is possible to produce the CF arrays of TFT-LCDs by the roll printing technology.
Printing technologies should be developed optimally for all processes of TFT-LCDs regarding each fields : Machines, Materials and Processes.

Speaker Biography (Soon-sung Yoo)

I'm a team leader of Future Process team of LG Display R&D Center.

My team is developing the new concept technologies of TFT-LCD processes for better performance and more cost effect.

I received BS and MS in physics from Kyung Hee University.

I developed TFT-LCD process technologies and set up the first fab. of TFT-LCD panels.

My research was mainly on process innovation and performance improvement for TFTs and achieved 3mask process for TFTs several years ago and now focus on some kinds of printing technologies for high resolution of TFT level and R2R technology for high productivity and flexible display.
