LG’s InstaView Door-in-Door refrigerator ($10,888) was recognised by Red Dot for successfully combining beautiful design with interactive technology. The refrigerator features a 29-inch LCD touch display, which instantly turns transparent with just two knocks, letting customers peer inside without opening the door. The Smart Tag menu lets users add stickers and tags on the screen to indicate which foods are stored inside, as well as input the expiration date of each item.
