Rollable OLED color display unveiled

The full-color, foldable display is a reality—in prototype, at least. Universal Display Corporation (UDC) has presented a prototype of a long hoped-for rollable display with full-color and full-motion. The screen measures 4 inches on the diagonal and consists of a flexible metal foil with an active-matrix OLED (or AMOLED) display. The whole thing (minus any support gear such as power supply, drive electronics, etc.) is about .1 mm thick and has a mass of less than 6 grams.

This flexible, full-color AMOLED prototype highlights several key advantages of the Company's proprietary OLED technologies over conventional liquid crystal displays (LCDs). Flexible OLED displays are significantly thinner and lighter weight than existing LCDs. The use of metal foil, instead of the glass that is typically used in LCDs, also offers significantly enhanced thermal and mechanical durability. These features may offer important advantages for today's cell phones, PDA's and lap-top computers.
