This new idea is for a TV that can detect your face!When you are in the room with the TV it realizes whether or not your attention is on the screen or somewhere else. When it is somewhere else such as on the phone, doodling, or reading a book, it automatically reduces the brightness so that it can reduce the amount of energy used. When your attention comes back to the TV and you are looking at it it goes back to regular so that it is easier to see.
