<p>An electronic visual display 445 (e.g. liquid crystal display or LCD screen) comprises a generally planer short-range antenna 411 incorporated in a layer of the display 445 (e.g. a reflective LCD layer, a membrane or a PCB) or mounted on the rear or front surface of the electronic visual display 445. The antenna 411 may be a near field communication (NFC) antenna with a conductive loop or track 463 which follows a path adjacent to a perimeter of the display 445. An industrial metering device 423 (e.g. flow, conductivity or power metres) may comprise the electronic visual display 445 located in or behind a window 431 of a housing 403. The antenna 411 and the display 445 may be connected to electronic circuitry via a shared connection 407.</p> |
