OLED panels are the next big thing when it comes to TVs and other consumer electronics. The OLED screen promises more compact dimensions, less power consumption and brighter images. Small OLED screens are currently found on some cell phones and LCD TV makers are looking for larger OLED screens to use in HDTVs. Reuters reports that Samsung recently unveiled a 31-inch active-matrix OLED screen. Samsung says it will have a 31-inch OLED prototype TV on display at CES 2008 in January.
