Flat panel displays (FPDs) are thin, flat, electronic devices used to display data. They are commonly used in notebook computers. Most styles include the housing and ports necessary to connect them to a computer.
Message LED displays are typically commercial or industrial signs. They allow for larger characters and longer viewing distances than their smaller digital cousins.
Liquid crystal display (LCD) modules are used at the component level in place of less efficient displays such as cathode ray tubes (CRTs). These modules do not include a housing and must be incorporated into a larger instrument or system.
