Patent ID: 8917254

Claim:
A touch unit comprising: multiple first axial electrodes extending in a first direction, each first axial electrode including multiple first sensing electrodes connected with each other and arranged in the first direction, each first sensing electrode being formed with a hollow section in a central position, each first axial electrode having at least one first extension end extending in two opposite directions along the first direction and each end of each first axial electrode having a second extension end extending in a single direction along the first direction, adjacent first and second extension ends defining therebetween a passageway in communication with the hollow section, wherein each second extension end and a respective horizontal portion thereof are connected with the adjacent first extension end and a respective horizontal portion thereof; and multiple second axial electrodes, each second axial electrode including multiple second sensing electrodes, each having a square shape, and multiple respective second connection lines, the second sensing electrodes being respectively disposed in the hollow sections of the first sensing electrodes, one end of the second connection line being connected with the second sensing electrode and extending in a second direction through the passageway.
