Sony has managed to make large OLED screens. At the Consumer Electronics Show here, Sony is showing off a 27-inch OLED panel, along with other, small OLED screens.
Still, a lot of work remains, and both executives emphasized that Sony is not announcing products or a definitive commitment to OLED TVs. The company, for instance, has to figure out how to mass-manufacture them at a price consumers are willing to pay. SED, a TV format promoted by Toshiba, has been delayed several times. Critics say that when it comes out, Toshiba will have challenges making SED, which stands for surface conduction electron emitter display, competitive in price with plasma or LCD.
