  • Publication number: 20170075462
    Abstract: The present disclosure relates to a touch screen panel and a touch display device. Several isolation electrodes are arranged in gaps between adjacent touch electrodes, and the isolation electrodes and the touch electrodes are insulated from each other. Therefore, even if a touch electrode and an adjacent isolation electrode are short-circuited during production, such a short circuit will only integrate the isolation electrode into part of the touch electrode while the isolation electrode is still insulated from other touch electrodes, since the isolation electrode is isolated from both other isolation electrodes and other touch electrodes. In this way, the risk of short circuits in the touch screen panel will be greatly reduced.
