SiPix is a developer and manufacturer of electronic paper. The company provides electronic paper materials, display modules, and system reference designs for specific applications. The company was founded in 1999 in Boston and moved to Silicon Valley in 2000. In 2009, AU Optronics invested in SiPix and the company moved its operations to Lingko, Taiwan.

Technology
SiPix material is based on electrophoretic display technology first demonstrated by Matsushita Electric Industrial Co, in 1969. Charged particles are dispersed in a non-polar fluid and move in the presence of an electric field. SiPix encapsulates the electrophoretic dispersion by means of micro-embossing and a proprietary sealing process. The company has coined the term Microcup® to describe the technology.

Product Applications
SiPix and Smart Displayer created the world’s first ISO7810 compliant display card in 2006. The card utilized the display to show a one-time-password for authentication purposes. SiPix partnered with Taiwan based ADATA in 2007 to create the world’s first SD flash memory with an incorporated display. The display showed the amount of free memory left on the device. In 2009, Western Digital launched a series of external hard drives with smart displays using SiPix technology. The display was used as a customizable “e-label” and showed the amount of free hard disk space.
