1. A microfluidic channel backplane, comprising:
a base;
a plurality of microfluidic channels disposed above the base, each microfluidic channel of the plurality of microfluidic channels including a first end and a second end;
a sample-adding channel communicated with first ends of the plurality of microfluidic channels, the sample-adding channel being configured to add a sample to be detected into the microfluidic channel backplane; and
an enrichment channel including a first enrichment sub-channel and a second enrichment sub-channel; the first enrichment sub-channel being communicated with second ends of the plurality of microfluidic channels, and one end of the second enrichment sub-channel being communicated with the first enrichment sub-channel; the enrichment channel being configured to receive the sample to be detected obtained after enrichment through the plurality of microfluidic channels, wherein
the sample-adding channel and the enrichment channel are disposed at a side of the plurality of microfluidic channels away from the base.
