Display glass to adapt to new apps, Corning exec says

Although the flat-panel LCD TV market will be a key driver for Corning Inc.'s glass development and expansion plans, system-on-glass applications, organic light-emitting diodes (OLEDs) and flexible substrates will also be in the mix, according to a company executive.

During a breakfast presentation at the Society for Information Display Conference Wednesday (May 25), Peter Bocko, division vice president and director of commercial technology for Corning's Display Group, said glass would serve as the platform for several value-added display applications.Bocko said he envisions display glass increasingly integrating circuit functions to improve functionality and lower cost.He also expects this approach to spawn more system-on-glass applications.

Attempting to debunk the myth of "disruptive" OLED technology, Bocko said many OLED displays would use the same active-matrix LCD platform, utilizing Corning glass materials.

Bocko said Corning was exploring development of non-glass materials for flexible substrates. He did not elaborate.

While most of Corning's glass is used for amorphous silicon thin-film transistor (TFT) substrates, Bocko said the company was increasing production of higher-grade glass for polysilicon TFT substrates heavily used in mobile LCD displays.

Bocko claimed Corning is the only supplier currently producing glass for seventh-generation fabs. He added the company is developing eighth-generation glass technology, though generation 10 glass technology might be the practical limit for glass makers due to issues such as handling, Bocko added.
