Japan’s Sony and South Korean rival Samsung are dissolving their joint venture in liquid crystal display panels as Sony tries to stanch years of losses in its TV business.

The joint venture called S-LCD was set up in 2004. Sony, which fell behind in flat panel TVs, invested in a Samsung panel factory to ensure a steady supply of panels for its LCD TVs.

Sony’s TV operation has lost money for seven straight years and the company is straining to return that key business to profit.

The prices of TVs as well as panels have been dropping so it makes more sense to buy panels at the market rate than to invest in production.

Sony, which makes Bravia TV sets, does not make its own LCD panels.

It said it will enter a new partnership with Samsung to buy panels, and will also continue buying panels from other manufacturers.

Sony said it will suffer a loss of 66 billion yen ($846 million) for the third quarter of this fiscal year, which ends later this month, because of the declining value of investment in S-LCD.

Getting out the production venture will produce substantial savings after January 2012, when the deal is completed, according to Sony.

It was still unclear how Sony’s profit forecast for the fiscal year through March 2012 will be affected, said company spokesman Takashi Uehara.
