An independent, stand-alone, battery powered information display module (1) to visually display computer generated, alpha-numeric information on one or more liquid crystal displays (4, 6). The module has particular application for storing and displaying pricing and related information associated with a shelf item commonly offered for sale in a retail establishment, such as a grocery store or the like. Pricing information is supplied by a computer (60) to the price display module for storage and eventual display by way of a hand-held, portable data terminal (52). The portable data terminal is electrically connected to the display module by a multi-terminal connector (54), whereby electrical contact pins (36, 37, 38) of the connector are aligned for engagement with respective electrical contact strips (8, 9, 10) located at the face of the display module and connected to the memory (40) thereof. A multi-conductor electrical cable (45) extends from the contact pins of the connector to be coupled to the portable data terminal to permit the two-way transfer of information between the memory of the display module and the computer. |
