Abstract
A touch-sensing electrode structure includes multiple first electrodes and multiple second electrodes. Each first electrode includes a longitudinal part extending in a first direction and multiple branch parts connected to the longitudinal part. The second electrodes are disposed on at least one side of each longitudinal part, and each of the second electrodes at least spreads over a region between two adjacent branch parts of each of the first electrodes.
