To provide the ultimate slimness in an OLED TV, the speaker and circuit parts have been separated and provided in an all-in-one external box. The 4mm ultra-thin screen sits completely flush to the wall to let viewers concentrate on the content they are watching. The all-in-one box which contains a 60W speaker provides rich sound while also allowing various devices to be connected to the box and providing use convenience. By adopting a simple shape design and using the thick, woven type of fabric used in curtains and sofas, it is designed to look and feel more like an interior design object rather than an electronic device.
