Definition of display

Marketing: merchandise arranged to catch the eye and attract attention, in order to promote sales. Displays are differentiated by their placement and type-for example, window displays, in-store displays, floor displays, or point-of-purchase advertising displays. There are also island displays or end-aisle displays, where the merchandise is stacked and readily accessible; upright displays especially made to hold the product; and cabinet displays (see display case), where the product is readily viewable but not accessible. Displays are used most frequently as collateral material in advertising campaigns, and show a relationship to the campaign through the use of an identifying mark as a visual symbol or logo.
Printing:
