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 capacitive 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.

Method for recognizing multiple capacitive styluses, touch control unit, touch panel and system

A touch display panel includes a TFT substrate, a CF substrate disposed above the TFT substrate, a liquid crystal layer sandwiched between the TFT substrate and the CF substrate, and a touch sensor formed on the CF substrate. The touch sensor includes a plurality of first electrodes, a plurality of second electrodes, a plurality of third electrodes, a plurality of bridges and an insulating layer. Each of the second electrodes is continuous, each of the first electrodes is interrupted by the second electrodes to form a plurality of electrode sections, and two adjacent electrode sections of the first electrode are electrically connected via a bridge. A plurality of blank areas are defined and surrounded by the first electrodes and the second electrodes, and the third electrodes are respectively disposed within the blank areas. The first electrodes, the second electrodes and the third electrodes are electrically insulated from each other.

Touch display panel and method for manufacturing the same

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.
