LG.Philips LCD Co. has developed what is says is the world's largest organic light-emitting diode (OLED) display panel with its sister firm LG Electronics Inc. OLED screens emit their own light, eliminating the need for backlighting and allowing equipment makers to develop slimmer and more power efficient monitors, which is just fine by us. Despite the competition from LCD products, the OLED market is supposed to grow from $429 million this year to $4 billion in 2008.
