Logic Controls pole displays are widely known as the market leaders for PC-based POS systems. They have long set the standard for reliability, value and functionality – reasons why most value-added resellers ask for Logic Controls displays by name.

One of the reasons why Logic Controls’ pole displays are the market leaders is because of their well deserved reputation for unsurpassed reliability. The LD9000 uses special display technology and unique circuit design to achieve this reliability. In addition, the units are made with special, high durability plastic that is UV-resistant and prevents color fading.

The LD9000 is a 2×20 line, 9.5mm character height display that comes with much functionality that simply is not found in other vendors’ offerings. “Smart scrolling,” user-definable characters, and a built-in real-time clock are all standard features of the unit’s firmware. In addition, the LD9000 comes with a wide variety of interfaces, can emulate many popular command sets, and has better visibility due to an optically matched lens and wider character pitch. Best of all, this premium pole display is also one of the most affordable on the market.
