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.
Oscilloscopes translate an electronic signal into a pattern or waveform on a screen. As it is traced across the screen, the waveform creates a signature of the signal's characteristics.
Radio frequency identification (RFID) products read or write data to RF tags that are present in a radio frequency field projected from RF reading/writing equipment.
