The paperlike display market has yet to home in on one type of technology. Currently, there are opportunities in improved color paperlike, fully flexible, low-cost paperlike and self-edge displays, and other labeling applications.
According to the report, both display technologies face challenges. One problem is with the substrates. To make truly flexible OLEDs and paperlike displays, flexible substrates must withstand manufacturing processes. Gasman said that, developing better substrates requires changes in processes rather than in materials. For example, the use of lasers for curing ink helps to focus the heat, so less is used over a shorter period.
The lack of technical expertise in printing for displays is another challenge. Gasman indicated that manufacturers are still unsure which printing process works best with displays. They must develop a sense of what works and what doesn’t, he said.
Another stumbling block is the low durability of blue OLEDs, which are essential for full-color displays. And, finally, there is a need for cost-effective conductive inks that can help produce large, high-resolution displays with long lifetimes.
