Pioneer is also asking NEC to buy back a plasma plant it bought from NEC 3 years ago for $400 million.
The company that is credited with delivering the best TV in the world will now focus on 50" or larger panels.
Last month research company DisplaySearch reported that Pioneer had witnessed a 39% decline in plasma sales Vs 62% growth in the overall plasma market during the last two quarters.
According to Reuters it would be Pioneer's latest step away from a vertically integrated business model, in which manufacturers conduct production of key parts as well as assembly of finished products, after its decision last year to buy liquid crystal display panels from Sharp Corp to start offering LCD TVs.
