GREAT WALL

Designer: SAMSUNG

Concept: THE WALL

Odds of production: EVEN BIG DREAMS CAN COME TRUE

At the annual Consumer Electronics Show in January, the major television manufacturers often attempt to grab headlines by showing off their ambitious visions for the future of visual displays — dazzling concepts that aren’t quite ready for prime time. This year, Samsung went big — literally — by introducing the Wall, a gargantuan screen measuring more than 12 feet diagonally and composed of an array of micro-LED panels. However, unlike other multiscreen displays, it is almost completely seamless — one has to walk right up to the screen to even notice the faint line between panels. Because they are modular, the micro-LED panels — which use light-emitting diodes (LEDs) smaller than a micrometer to produce a vibrant 4K picture — can theoretically be arranged in any configuration and to any desired size. — JOHN LYON
