As usual with OLED displays, we're taking one step forward only to find there are hundreds more to go. LG has today officially announced a new $226 million investment in its OLED production facilities, which will markedly expand its ability to churn out ultrathin canvases of wonder. The not so good news, however, is that this production line is still being built -- with a planned activation in the third quarter of 2010 -- and the effects of the new cash infusion will not be felt until the second half of next year. Should you have the patience to endure such protracted roadmaps, you should be seeing a lot more from LG in the mobile display space -- where Samsung currently holds the technological lead with its Super AMOLED screens -- as well as the luxury TV market that already counts the 15-inch 15EL9500 among its numbers. The Korean manufacturer describes OLED screens as one of its "new growth engines," alongside e-paper and solar cells, so even if we may consider development slow, it's looking increasingly likely that OLED TVs will eventually make their way into the mainstream.
