"because people would laugh at them". Canon also had an ongoing OLED development process that started in the midst of the lawsuit. In 2007 they announced a joint deal to form "Hitachi Displays Ltd.", with Matsushita and Canon each taking a 24.9% share of Hitachi's existing subsidiary. Canon later announced that they were purchasing Tokki Corp, a maker of OLED fabrication equipment. In April 2009 during NAB 2009, Peter Putman was quoted as saying "I was asked on more than one occasion about the chances of Canon's SED making a comeback, something I would not have bet money on after the Nano Technologies licensing debacle. However, a source within Canon told me at the show that the SED is still very much alive as a pro monitor technology. Indeed, a Canon SED engineer from Japan was quietly making the rounds in the Las Vegas Convention Center to scope out the competition." Canon officially announced on 25 May 2010 the end of the development of SED TVs for the home consumer market, but indicated that they will continue development for commercial applications like medical equipment. On 18 August 2010, Canon decided to liquidate SED Inc., a consolidated subsidiary of Canon Inc. developing SED technology, citing difficulties to secure appropriate profitability and effectively ending hopes to one day see SED TVs in the home or the room or the living room.
