A touch display module includes a display panel and a touch sensing layer. The touch sensing layer is embedded in the display panel and includes a plurality of sensing electrode groups. The sensing electrode groups are sequentially arranged along a first axial direction. One of the sensing electrode groups includes a first electrode block, a second electrode block, and a third electrode block spaced apart from each other. The first electrode block is located at a same side of the second electrode block and the third electrode block in the first axial direction and is located between the second electrode block and the third electrode block in a second axial direction perpendicular to the first axial direction.

Touch display module, electronic apparatus, and touch position detection method

An electronic device with touch sensing function is provided, which includes multiple touch structures arranged along an X-axis. Each touch structure includes a first electrode, a second electrode, and a third electrode. The first electrode includes an upper-half electrode and a bottom-half electrode coupled with each other. The upper-half electrode and the bottom-half electrode extend toward each other along a Y-axis and are both substantially triangular, and the X-axis is substantially perpendicular to the Y-axis. The second electrode is substantially triangular, and a first side and a second side of the second electrode face the bottom-half electrode and the upper-half electrode, respectively. The third electrode is disposed between the bottom-half electrode and the first side of the second electrode, and the third electrode is substantially strip-shaped.
