Future Sony large-sized liquid crystal displays (LCDs) will be probably made by LG Display, according to sources.

Earlier this week the Korea Times reported that LG Display was in 'advanced talks' with Sony to supply large-sized LCDs for the Japanese maker's high-end flat-screen televisions.

"We are negotiating with Sony to expand LCD supplies toward large-sized ones," LG Display chief executive officer (CEO) Kwon Young-soo said on the sidelines of a technology forum in Seoul, although refusing to discuss the details of the talks as the agreement hasn't been finalized.

LG Display is already providing Sony with LCD panels used for screens in portable devices and small-to-mid-sized televisions in the 20- and 30-inch range. However, adding Sony to its list of premium customers would boost LG Display's attempt to overtake domestic rival Samsung Electronics for supremacy in the flat-screen industry.

Sony and Samsung have been operating an LCD joint venture in Korea since 2004. However, it seems that Sony is trying secure a stable LCD supply for its large-panel TVs form a different source.

LG Display has been a major screen provider for Apple over the past years by providing the panel of the iPad and the new iPad 2 models.
