Claim 0:
1. A display panel, comprising a display substrate and pixel units, wherein a multiplexing circuit and the pixel units are arranged on a first surface of the display substrate, the display panel further comprises a wave-absorbing material layer arranged on a second surface of the display substrate, the wave-absorbing material layer is configured to absorb electromagnetic wave interference signals;
the second surface is a surface opposite to the first surface;
the multiplexing circuit comprises N input pins and M output pins, N is different from M, and N and M both are positive integers; and
the input pins are connected to a driver integrated circuit and the output pins are connected to the pixel units;
wherein the first surface comprises a display region and a peripheral region at a periphery of the display region; the second surface comprises a first region and a second region; an orthographic projection of the display region onto the second surface overlaps the first region, and an orthographic projection of the peripheral region onto the second surface overlaps the second region; the multiplexing circuit is arranged in the peripheral region;
the display panel further comprises a first back film layer arranged in the first region of the second surface; and
the wave-absorbing material layer is arranged on a side of the first back film layer that is far away from the display panel;
or,
the first surface comprises a display region and a peripheral region at a periphery of the display region; the second surface comprises a first region and a second region, an orthographic projection of the display region onto the second surface overlaps the first region, an orthographic projection of the peripheral region onto the second surface overlaps the second region; and
the wave-absorbing material layer is arranged in the first region and the multiplexing circuit is arranged in the peripheral region;
wherein the display panel further comprises a first heat-dissipation film layer, wherein the first heat-dissipation film layer and the wave-absorbing material layer are arranged at a same level, and an orthographic projection of the first heat-dissipation film layer onto the second surface and an orthographic projection of the wave-absorbing material layer onto the second surface are both in the first region; and
wherein the display panel further comprises a second heat-dissipation film layer, wherein the second heat-dissipation film layer is arranged on a side of the first heat-dissipation film layer that is far away from the first back film layer; an orthographic projection of the second heat-dissipation film layer onto the second surface at least covers the orthographic projection of the first heat-dissipation film layer onto the second surface and the orthographic projection of the wave-absorbing material layer onto the second surface.
