Imaging Backplane, Driving Method Thereof and Fingerprint Identification Panel

An imaging backplane, comprising:

• M rows and N columns of imaging structures, 2M rows of first signal lines, 2N columns of second signal lines, a first reset sub-circuit and a second reset sub-circuit,
• wherein each imaging structure comprises a first imaging unit and a second imaging unit, the first imaging unit of the imaging structure of row i and column j is connected with the first signal line of row 2i-1 and the second signal line of column 2j-1 respectively, and the second imaging unit of the imaging structure of row i and column j is connected with the first signal line of row 2i and the second signal line of column 2j respectively, wherein 1≤i≤M and 1≤j≤N;
• the first reset sub-circuit is respectively connected with a first reset terminal, a low-level power supply terminal and the second signal lines of all odd-numbered columns, and is configured to provide a signal of the low-level power supply terminal to the second signal lines of all the odd-numbered columns under control of the first reset terminal, to reset the first imaging units;
• and
• the second reset sub-circuit is respectively connected with a second reset terminal, the low-level power supply terminal and the second signal lines of all even-numbered columns, and is configured to provide the signal of the low-level power supply terminal to the second signal lines of all the even-numbered columns under control of the second reset terminal, to reset the second imaging units.
