1. A display panel, comprising:
a transparent substrate;
a plurality of electrode blocks on the transparent substrate, wherein each of the plurality of electrode blocks comprises a closed-shaped slit;
a plurality of conductive bonding blocks, wherein each of the plurality of conductive bonding blocks is on a surface of a corresponding one of the plurality of electrode blocks away from the transparent substrate and each of the plurality of conductive bonding blocks is partially embedded in the slit of the corresponding one of the plurality of electrode blocks; and
a plurality of micro light emitting diodes (micro LEDs), wherein each of the plurality of micro LEDs is fixed on and electrically connected to a corresponding one of the plurality of electrode blocks by the corresponding one of the plurality of conductive bonding blocks, along a thickness direction of the display panel, a projection of each of the plurality of micro LEDs on the transparent substrate partially covers the slit of the corresponding one of the plurality of electrode blocks, and a portion of the slit not covered by the plurality of micro LEDs is configured for transmitting light, such that light emitted by the micro LEDs transmits through a portion of the slit not covered by the plurality of micro LEDs to a side of the transparent substrate away from the plurality of micro LEDs.
