Abstract
A system for electronically displaying sales item data such as price and item description on store shelves utilizes a central store microprocessor/computer to control the display system. Standard shelf display tags are replaced by an electronic display device and display bus system. The display bus system is comprised of a printed circuit board, with conductors which run parallel so that electrical contact can readily be made by a display module which is mounted to the printed circuit board. All of the store shelf edge channels are installed with a printed circuit board electronic bus system. In an alternate embodiment a fully integrated display strip is substituted for individual display modules. A central controller processes information from a store computer signal and sends the information to the display modules or display strips using a specialized signal format comprised of a series of tones with frequencies less than 10,000 khz. Item descriptions, sales prices, sales alerts, regular prices, and per unit quantity prices can all be added or changed via a central store computer.
