  • Patent number: 11586328
    Abstract: A circuit board includes multiple of first touch sensing electrodes, multiple of second touch sensing electrodes, and multiple of dummy patterns. The first touch sensing electrodes extend along a first direction. The second touch sensing electrodes extend along a second direction. The first touch sensing electrodes are electrically insulated from the second touch sensing electrodes. The first direction is not parallel to the second direction. The dummy patterns are positioned on the areas between the first touch sensing electrodes and the second touch sensing electrodes. The first touch sensing electrodes, the second touch sensing electrodes, and the dummy electrodes are non-transparent.

  • Patent number: 11442585
    Abstract: 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.

  • Patent number: 11416106
    Abstract: An electronic device with touch sensing function is provided, which includes first touch electrodes, second touch electrodes, and pixel circuits. The first touch electrodes are in parallel with a Y-axis, in which each first touch electrode includes first electrode blocks and bridge patterns. The first electrode blocks are coupled with the bridge patterns in series. The second touch electrodes are in parallel with an X-axis, in which each second touch electrode includes second electrode blocks and connection patterns. The second electrode blocks are coupled with the connection patterns in series and the X-axis is substantially perpendicular to the Y-axis. The pixel circuits are arranged as corresponding to the first touch electrodes and the second touch electrodes in a projection direction. The pixel circuits are configured to receive one or more voltages from the first touch electrodes and the second touch electrodes.

  • Patent number: 11086466
    Abstract: 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.
