Abstract: An electrode structure of a capacitive touch panel is provided, which includes a plurality of receiving electrodes and a plurality of driving electrodes. Each of the receiving electrodes has a hexagonal electrode structure. Each of the driving electrodes includes a main region. Each of the main regions has a quadrilateral electrode structure. The area of each driving electrode is larger than that of each receiving electrode. By using the foregoing electrode structure, the capacitive touch panel can not only provide sensing signals with less noise but also increase the intensity of input signals to enhance the signal to noise ratio.

Abstract: A capacitive touch panel is disclosed to include a plurality of sensing channels disposed along a first direction and a second direction, respectively, and including a plurality of sensing modules. Each of the plurality of sensing modules includes a sensing unit and a plurality of dummy units being separately disposed to form a plurality of boundaries. A plurality of extension rays of the plurality of boundaries, the first direction and the second direction are interlaced to form a plurality of angles being in the range from zero degrees to ninety degrees or from ninety degrees to a hundred and eighty degrees. A plurality of connecting units is disposed along the first direction and the second direction for connecting the plurality of sensing modules. The first direction is perpendicular to the second direction and the plurality of sensing channels is perpendicular to each other on a projective plane.

Abstract: A synchronization method for an active stylus includes transmitting a first downlink signal according to at least one first timing parameter, configured for a first touch device, after the active stylus moves to the first touch device, and transmitting a second downlink signal according to at least one second timing parameter, configured for a second touch device, after the active stylus moves to the second touch device. With the synchronization method and its control circuit, the active stylus can communicate to various touch devices accurately or communicate to different touch devices alternately, even though the active stylus may move from one touch device to another.
