Abstract
A plasma display electrode short circuit and broken circuit detecting method and a device are provided. The detecting circuit comprises FPC electrode connecting films, connecting film sockets on a circuit board and a detecting circuit board. Column and row FPC films lead out electrodes to be detected to interface sockets of column and row detecting circuit boards, thus ensuring each electrode is independent and no physical connection exists between electrodes. In addition, a LED is connected with each electrode. A voltage of 5V is imposed to one end of the electrode to confirm whether the connected electrode suffer from short circuit or broken circuit according to brightness of different LED and find out which electrode undergoes problems.
