Visual Display Unit


(VDU, or "video terminal", "video display terminal", VDT, "display terminal") A device incorporating a ref="module.php?name=Lexikon&file=search&eid=1&query=cathode ray tube">cathode ray tube (CRT) display, a keyboard and a {serial port}. A VDU usually also includes its own display electronics which store the received data and convert it into electrical waveforms to drive the CRT. VDUs fall into two categories: ref="module.php?name=Lexikon&file=search&eid=1&query=dumb terminals">dumb terminals and ref="module.php?name=Lexikon&file=search&eid=1&query=intelligent terminals">intelligent terminals (sometimes called "programmable terminals"). Early VDUs could only display characters in a single preset ref="module.php?name=Lexikon&file=search&eid=1&query=font">font, and these were confined to being layed out in a rectangular grid, reproducing the functionality of the paper-based ref="module.php?name=Lexikon&file=search&eid=1&query=teletypes">teletypes they were designed to replace. Later models added graphics facilities but were still driven via serial communications, typically with several VDUs attached to a single multi-user computer. This contrasts with the much faster single ref="module.php?name=Lexikon&file=search&eid=1&query=bitmap displays">bitmap displays integrated into most modern single-user ref="module.php?name=Lexikon&file=search&eid=1&query=personal computers">personal computers and ref="module.php?name=Lexikon&file=search&eid=1&query=workstations">workstations. The term "Display Screen Equipment" (DSE) is used almost exclusively in connection with the health and safety issues concerning VDUs. {Working with VDUs - UK Heath and Safety Executive (http://www.hse.gov.uk/pubns/indg36.pdf)}.
