Samsung confirmed on Friday that its 55-inch OLED SMART HDTV will be shown at Berlin IFA trade show in late August. Samsung describes the new televisions as even "more premium" than its OLED models, although that may be in terms of functionality rather than design or display technology.

Samsung unveiled its OLED TV at the Consumer Electronics Show in January, however details remain scarce. Both television sets will reportedly support the newest iteration of Samsung AllShare, which will add a 5GB cloud account to its local DLNA-based service, along with a remote login system, in the latter part of 2012. Using a single account login, the feature will allow users to remotely access any of their Samsung devices located anywhere in the world.
