Delta Electronics is ready to begin volume production of electrophoretic display (EPD) products in 4.1-, 8.2-, 13.1- and even 21-inch sizes targeting niche market applications, including industrial applications, frozen warehouses and out-door signage, according to the company.

Delta is currently showcasing its EPD products at the ongoing Computex 2011 with the 13.1-inch models receiving the most inquiries from potential buyers, the company noted.

The display of the 21-inch e-paper is to demonstrate Delta's steadiness and cost control in EPD production, said the company.
