An anonymous reader writes "If you want a large, interactive display on your wall, typically you have to make space for it by moving any pictures out of the way, and finding room next to any shelves or lighting you have installed. Samsung's idea is to remove that problem by creating a transparent display that replaces an actual window, or at least sit over the top of one. The display uses ambient light during the day and then can switch over to a more traditional black background as a night time mode. If you want to shut the daylight out it has virtual blinds you can draw to help darken a room. And from the outside you just like you are tapping your window as none of the graphics can be seen. Yes, your neighbors will talk."
