1. A display module, comprising an active area and a bonding region located at one side of the active area; wherein a plurality of touch signal lines and a plurality of common-electrode units are provided within the active area, and the common-electrode units are electrically connected to the touch signal lines; at least one driving chip is provided within the bonding region; the display module further comprises a mainboard, and the mainboard comprises a power-supply chip;
each of the at least one driving chip comprises a plurality of output terminals and at least one input terminal; the output terminals are electrically connected to the touch signal lines, and each of the at least one input terminal is electrically connected to the power-supply chip;
each of the at least one driving chip comprises a first side edge and a second side edge that are opposite, and both of the first side edge and the second side edge extend in a direction from the active area pointing to the bonding region; and
for a same instance of the at least one driving chip, a resistance value between a first output terminal of the driving chip and the power-supply chip is substantially equal to a resistance value between a second output terminal of the driving chip and the power-supply chip, wherein the first output terminal refers to an instance of the output terminals that has a lowest distance to the first side edge, and the second output terminal refers to an instance of the output terminals that has a lowest distance to the second side edge.
