ELECTRIC SIGN BOARD DRIVING SYSTEM CAPABLE OF STABLY OUTPUTTING AN IMAGE THROUGH AN ELECTRIC SIGN BOARD, AND A METHOD THEREOF

摘要

PURPOSE: An electric sign board driving system and a method thereof are provided to improve the reliability of a product and to reduce errors regarding the operation time of an electric sign board.;CONSTITUTION: An image processor(1) selectively receives image information from at least two display systems(3,4). The image processor compares the frame data which is included in the image information according to a time difference. The image processor determines whether the display system, which provides present image information, is normally operated. When the present display system is in an abnormal state, the image processor receives the image information from a different display system. An electric sign board(5) outputs the image information of the image processor.;COPYRIGHT KIPO 2011
