To create such a thin display Sony used a new organic semiconductor material it developed called peri-Xanthenoxanthene (PXX), which is resistant to oxygen, moisture, light, and heat exposure. The new display is also the first flexible organic thin-film transistor (OTFT) that uses something called an integrated flexible gate-driver circuit, allowing Sony to lose the rigid driver IC chips usually found in other types of displays.
The video above shows the display being rolled and unrolled around a cylinder 4 millimeters in diameter. Although image quality is not flawless -- in fact some funky horizontal and vertical lines are visible -- it still represents a breakthrough in this area of display research. The technology will be shown off this week at the Society for Information Display 2010 International Symposium in Seattle.
