Abstract
A touch display panel which includes a first substrate, a second substrate, at least a multi-sensing structure, a display medium and at least a display controlling device is provided. The multi-sensing structure is disposed between the first substrate and the second substrate, and the multi-sensing structure includes a sensing upper electrode and a plurality of first sensing lower electrodes. The sensing upper electrode is disposed on the second substrate. The first sensing lower electrodes are disposed on the first substrate and electrically connected to each other in series, wherein a plurality of first sensing gaps are designed between the first sensing lower electrodes and the sensing upper electrode, and the first sensing gaps have different distances. The display medium is sandwiched between the first substrate and the second substrate. The display controlling device is disposed on the first substrate for controlling the display medium.
