From the press release:
Yuan Tai Technologies Inc. announced today that it has changed the international version of its name from Prime View International (PVI) to E Ink Holdings Incorporated (E Ink). This change was approved at the Annual General Meeting held today. With this change Yuan Tai Technologies reaffirms its strong commitment to ePaper, an industry that it has pioneered for over a decade.
Back before PVI bought E-ink, PVI were the manufacturing licensee for E-ink's screen technology patents. Then PVI bought E-ink last year, and now they've changed the company name to reflect the high profile subsidiary. It was a good move.
