Taiwan-based EPD (electrophoretic display) maker E Ink Holdings (EIH) brought in consolidated revenues of NT$2.086 billion (US$72.3 million) for May, slipping 15.38% on month but rising 17.75% on year. January-May revenues of NT$14.637 billion increased 72.62% on year, according to the company.

The sequential decrease was mainly due to decreased shipments of FFS (fringe field switching) TFT-LCD panels produced by its South Korea-based subsidiary Hydis, E Ink indicated. Many clients have adjusted their tablet PC product plans and rescheduled shipments of FFS panels from the second quarter to the third quarter, E Ink said.

But E Ink has seen booming shipments of EPD to North America, Europe and Russia markets and expects to ship 20-30 million EPDs in 2011, double or triple its 2010 shipments.
