1. A display panel, comprising:
a first voltage terminal;
a gate driving circuit, wherein the gate driving circuit comprises multiple stages of first output terminals, and the multiple stages of first output terminals sequentially output shift signals at intervals; and
a detection circuit, comprising:
a voltage divider circuit connected between the first voltage terminal and a reference voltage terminal, wherein the voltage divider circuit comprises multiple stages of voltage output terminals, and the voltage output terminals are arranged in one-by-one correspondence with the first output terminals;
multiple first switching units arranged in one-by-one correspondence with the multiple stages of voltage output terminals, wherein control terminals of the first switching units are connected to the voltage output terminals corresponding thereto, and first terminals of the first switching units are connected to a first power supply terminal; and
multiple second switching units arranged in one-by-one correspondence with the multiple first switching units, wherein control terminals of the second switching units are connected to the first output terminals corresponding thereto, first terminals of the second switching units are connected to second terminals of the first switching units corresponding thereto, and second terminals of the second switching units are connected to a second output terminal.
