After outing business dealings with Apple, Pixelworks appoints ex-Apple exec to board

The newly-elected Pixelworks board member worked at Apple from 2001 to 2011, during which time he moved from manager to vice president of hardware engineering and technology, reports BusinessWire. During his tenure, Tupman led teams working on mobile devices like the iPhone and iPod.

"It gives me great pleasure to welcome David Tupman to Pixelworks' board of directors," said President and CEO of Pixelworks Bruce Walicek. "David's extensive experience in management and advisory roles at leading consumer electronics and industrial companies will add immeasurable value to the Board. The Board and I look forward to working with him as we continue to execute on our strategy of bringing the very highest video quality to all screens."

In March, a Pixelworks filing with the U.S. Securities and Exchange Commission revealed business from Apple represented over ten percent of its revenue for 2013. Other big-name companies mentioned in the report include Hitachi and NEC, while the firm is known to have held previous dealings with Panasonic and Seiko Epson.

What exactly Apple purchased from Pixelworks is unknown, as are any outstanding orders for 2014.

Pixelworks specializes in video and pixel processing hardware and software that could theoretically benefit Apple's Retina displays. Of note, one of the company's target markets is portable device screens, an area where Apple has traditionally been an industry leader.
