Flat-panel displays have been in use in television receivers and computer monitors since the early 1980s. Strictly speaking, all electronic display devices, except the cathode ray tube (CRT) can be classified as flat panel types. But Sony introduced a flat CRT television (Trinitron™) as early as 1982. What the world is waiting for now is the thin flat-panel display, which can be hung on a wall like a picture. However, in spite of early optimism after its introduction some years ago, lowering the cost of materials for the monolithic types and, more particularly, the assembly costs of hybrid devices have posed far greater problems in practical applications than originally expected.
