| It has been recognized that LED display used in the freeway should have a feature which the system can report in real time the LED open-circuit or short-circuit errors. Macroblock's LED Drivers with Error Detection can meet such requirements. Thus, when the messages of traffic conditions are correctly displayed, the display error, if any, will be reported immediately to the central office. In addition, the backward compatibility is featured by exploiting Macroblock's Share-I-O™ Technique. The customer can easily upgrade from legacy design. With such solution, the customer has given its credit to Macroblock for the successful implementation of the LED display for freeway traffic information in Korea. |
