1. A micro light-emitting diode display panel, comprising:
a plurality of display units arranged in an array and each of the plurality of display units comprising a first sub-pixel, wherein the first sub-pixel comprises a first micro light-emitting diode and a second micro light-emitting diode with the same color of the first micro light-emitting diode; and
a control element configured to control light emission of the first micro light-emitting diode and the second micro light-emitting diode and determine operating currents of the first micro light-emitting diode and the second micro light-emitting diode,
wherein in a same display image, the operating current of the first micro light-emitting diode increases as an operating temperature of the first sub-pixel increases, and
wherein an impedance of the first micro light-emitting diode is smaller than an impedance of the second micro light-emitting diode.
