Flexible touch display panel

摘要

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. One example of crack-spread impeding choke points is that of shaping each electrode to have dose but spaced apart openings for example in a grid pattern.

1. A flexible touch display panel comprising:
a display device including a substrate, a display unit formed on the substrate, and an encapsulation film formed on the display unit to encapsulate the display unit; and a touch film that is arranged on the display device, including a plurality of interconnected first sensing electrodes and a plurality of interconnected second sensing electrodes that are electrically insulated from the first sensing electrodes and yet predominantly formed in a same layer as that of the plurality of first sensing electrodes, wherein each of the plurality of first sensing electrodes includes:
first electrode patterns that are each independently longitudinally extending according to a certain first direction and arranged in parallel to one another; andfirst connecting patterns for connecting neighboring electrode patterns among the first electrode patterns.
