1. A display module, comprising:
a display panel, wherein a non-display surface of the display panel includes a plurality of side edges, and the plurality of side edges include at least one selected side edge; the display panel includes a plurality of bonding electrodes disposed on the non-display surface, and the plurality of bonding electrodes are sequentially arranged at intervals along a selected side edge; the plurality of bonding electrodes are divided into a first bonding electrode group and a second bonding electrode group; the first bonding electrode group includes a portion of the plurality of bonding electrodes, and the second bonding electrode group includes another portion of the plurality of bonding electrodes;
a first flexible circuit board having a first wiring region and a first fan-out region that are connected to each other, wherein the first wiring region is closer to the selected side edge than the first fan-out region; the first flexible circuit board includes a plurality of first conductive contact pieces that are arranged at intervals in the first wiring region; and each first conductive contact piece is electrically connected to a bonding electrode in the first bonding electrode group; and
a second flexible circuit board having a second wiring region and a second fan-out region that are connected to each other, wherein the second wiring region is closer to the selected side edge than the second fan-out region; the second flexible circuit board includes a plurality of second conductive contact pieces that are arranged at intervals in the second wiring region; and each second conductive contact piece is electrically connected to a bonding electrode in the second bonding electrode group,
wherein the first wiring region is closer to the selected side edge than the second wiring region in a first direction; the first fan-out region and the second wiring region have a distance therebetween in a second direction; the first direction is perpendicular to the second direction; and the second direction is an extension direction of the selected side edge; and
in the second direction, a minimum distance between the first fan-out region and the second wiring region is greater than 1 mm.
