flat-screen
Synonym discussion
Sense: noun/1
Flat-screen is a general term for any thin television or monitor, regardless of the technology inside. LCD (liquid crystal display) and LED TV are specific display technologies that happen to be flat, but a flat-screen could also use other technologies. Plasma screens were an early flat type that used gas cells, but they are no longer common. In everyday conversation, people often use 'flat-screen' to mean any modern TV, while 'LCD' is more technical. For example: 'Let's buy a new flat-screen for the game room' (general) vs. 'This LCD panel has better colour accuracy' (technical, computer use).

Etymology
A modern compound formed from 'flat' (meaning level, even — from Old English 'flett') and 'screen' (a display surface — from Middle English 'screne', borrowed from Old French 'escren', meaning a shield or partition). The term became common in the 1990s and 2000s as LCD and plasma display technology replaced the bulky cathode-ray tube (CRT) televisions and monitors that had dominated since the mid-20th century.
