Patent number: 9164612Abstract: The spread of nascent cracks through a flexible electrodes layer is blocked or impeded by patterning at least one of the electrodes to have crack-spread blocking boundaries and/or crack-spread impeding choke points, where the crack-spread blocking boundaries are placed to block linear growth of cracks and the crack-spread impeding choke points are placed and sized to serve as bottlenecks that impede linear growth of cracks through the corresponding electrode. Additionally, greater flexibility is provided by including a pattern of elongated strips of narrow width electrode material longitudinally extending in different directions, where the provided flexibility is greater than what it would be if a pattern of elongated narrow width electrode strips longitudinally extending in different directions was not provided. One example of crack-spread blocking boundaries and flexibility enhancing patterning is that of shaping each electrode to have serpentine fingers extending longitudinally in different directions.Type: GrantFiled: December 11, 2013Date of Patent: October 20, 2015Assignee: Samsung Display Co., Ltd.Inventor: Byung-Hoon Chae
