TV-Lift
A Television-lift, TV-lift for short, or also TV lifting system, is an electrically powered mechanical system which lifts or moves televisions vertically or horizontally out of furniture, ceilings or partition walls. The main reason for using a TV lift system is in order to integrate a television into the existing interior design of a room without the television disrupting the overall design appearance. Due to the high overall project costs associated with TV lifts, they are regarded as a luxury product and are as a consequence most commonly to be found in more up-scale homes and apartments, conference rooms, private jets or yachts.
== History ==
The first TV lifts were launched on the market in the USA at the beginning of the1950s. As a consequence of the fact that the cathode-ray televisions of the time were usually heavy and bulky, the first TV lifts were also very large and bulky constructions which required quiet a large amount of space for their installation. At the beginning, there were primarily TV lifts which lifted the cathode-ray television upwards out of a piece of furniture or a room divider. The vertical ceiling lifts first came onto the scene in the mid-1970s as a result of the television manufacturing industry by that time having developed cathode-ray televisions which were flatter and lighter. At the beginning of the new millennium in the year 2000, plasma display televisions were introduced which meant that more compact systems (flat-lift devices) became available on the market. After the lighter LED televisions replaced the plasma screen technology in 2011, the technology could be refined even further.
