The LCD equivalent of a format war is in the works

Competition between Samsung LCD and LG.Philips LCD (LPL) has never been stronger: both companies just officially declared differing next generation LCD standards.  Since LCD substrate factories are so expensive to manufacturer (usually in excess of a billion dollars), all manufacturers of LCDs typically abide by "generation" standards so that component supplies do not need to constantly change.  For example, Samsung, LG.Philips LCD and AUO 7G facilities all produce glass substrates with dimensions of 1950x2250mm.  All 6G facilities produce glass with dimensions of 1850x1500mm.

DisplayBank reports that LG.Philips LCD has declared the 8G standard to be 2160x2400mm -- the resulting substrate can be cut into exactly eight 47" LCD screens or exactly six 52" screens.  Samsung LCD has declared the official 8G standard to be 2160x2460mm, which can be cut into eight 46" LCDs or six 52" screens. 

The rift in standards agreement ultimately will hurt consumers as component manufacturers will have to manufacturer components that will work for the 47" and 46" format sizes -- or chose to support only a single format size.  Ultimately, this will lead to component cost increases.  Typically, the LG.Philips LCD has been the first to market, and thus all other LCD substrate standards were based off panel sizes set by LPL.
