1. A touch module, comprising: a substrate and at least one group of touch patterns, each group of touch patterns comprising:
a conductive bridge, formed on one side of the substrate and having a plurality of bridging positions arranged at intervals in a first direction;
an insulating support portion, formed on the one side of the substrate and provided on the conductive bridge, the insulating support portion comprising a plurality of first support portions arranged at intervals in the first direction, and a second support portion located between adjacent first support portions, the first support portion and the second support portion adjacent being separated from each other by at least one first partition opening, each of the first support portions corresponds to one of the bridging positions, and the first supporting portion has a via hole exposing the bridging position; and
a touch electrode portion, comprising a plurality of first touch electrodes arranged at intervals in the first direction, and a second touch electrode located between adjacent first touch electrodes and insulated from the first touch electrodes, each of the first touch electrodes being formed on one of the first support portions and electrically connected to the bridging position through the via hole, and each of the second touch electrodes is formed on the second support portion.
