The time period during which an individual message is on display. Posters are normally contracted on a monthly basis, rotating bulletins typically display for a two-month period, and the term for permanent bulletins depends on the individual contract.
In a statistical report, the display period is the time between each generated statistic. The report period is the time between the first and last display period. For example, if viewing a report of 24- one hour values, the display period is 1 hour and the report period is 1 day.
