Abstract: The present disclosure provides a display panel and a display device. The display panel includes a plurality of fingerprint recognition circuits. At least one of the plurality of fingerprint recognition circuits includes a light sense signal obtaining unit and a subtracted. The light sense signal obtaining unit is configured to obtain a first light sense voltage value and a second light sense voltage value, the first light sense voltage value is related to a first power voltage value, the second light sense voltage value is related to a second power voltage value, and the first power voltage value is greater than the second power voltage value. The subtracted is configured to subtract the second light sense voltage value from the first light sense voltage value to obtain a light sense data value.
