摘要： The present invention discloses a method for recognizing multiple active capacitive styluses, a touch control unit, a touch panel, and a touch system. The method includes the steps of: obtaining recognization signals sent by multiple active capacitive styluses, and recognizing coordinates of each active capacitive stylus and its report point removing ghost point coordinates from the report point coordinates in a mutual capacity mode of a work cycle of a touch panel, to obtain actual coordinates of each active capacitive stylus. The present invention accurately recognizes the specific positions of the multiple active capacitive styluses by eliminating the coordinates of the ghost points and has the advantages of high positioning accuracy and strong user experience.

摘要： A touch panel includes a transparent substrate and a sensing pattern formed on the transparent substrate. The sensing pattern is in the form of a mesh structure. The mesh structure includes a plurality of conductive wires intersecting with each other to form a plurality of grids and a plurality of nodes connected between the grids. The grids are formed by the conductive wires intersecting with each other, and the nodes are formed at the intersection points of the conductive wires. The node has an annular shape with a center hole being defined in a center portion of the node. Due to the nodes having an annular shape, the surface resistance at the nodes is decreased and the signal attenuation is accordingly reduced. The conductive wires are connected firmly without the risk of breakage after the sensing pattern is formed.
