Samsung designed The Frame TV  to look like a piece of art with a completely flush mount, thin frame, motion sensor, brightness sensor, and an invisible connection.

Samsung's The Frame is a TV that's just as much a piece of art as it is a television. Switch it on and it's a 4K Ultra HD; switch it off and it'll display any of hundreds of pieces of art.
Instead of turning off like a normal TV, leaving a blank black rectangle on the wall, The Frame TV is designed to always show its picture when someone is in the room. It uses a motion sensor that keeps the image onscreen as long as it senses movement. 
The virtually undetectable invisible connection replaces unsightly TV cables, leaving your space beautifully uncluttered.
The customizable Frame has the flexibility to fit into any home’s décor. You can change the black bezel to a wood, white, or metal frame, perfectly complementing your home.
The Samsung Frame TV is available in 55-inch size for 1,999 USD and the 65-inch size for 3,299 USD.
