During a session at the Flexible Display Conference here earlier this week, a presentation updating the cost model in roll-to-roll manufacturing painted a less-than-glowing picture of the technique. Presented by consulting firm Abbie Gregg Inc. (Tempe, Ariz.), the study concluded that a combination of high costs and poor availability of production tools are hindering the adoption of roll-to-roll manufacturing.

The study found that the tooling cost of setting an active-matrix flexible organic light-emitting diode (OLED) substrate line amounted to roughly $177 per square foot. The cost of tooling a passive-matrix polymer light-emitting diode (PLED) line is far less, at $45 per square foot.
