Abstract
The present disclosure provides a display panel, a method for driving the display panel, and a display device. The display panel includes a control unit including first and second processing circuits. A pixel circuit located within the fingerprint recognition region is connected to the first and second processing circuits of the corresponding control unit. In the fingerprint recognition mode, a pixel circuit located within the non-fingerprint recognition region receives a first light emission control signal, so that the light-emitting element does not emit light in first period and second sub-period and emits light in first sub-period. The second processing circuit provides a second light emission control signal, and a pixel circuit located within fingerprint recognition region responds to the second light emission control signal, so that the light-emitting element does not emit light in first period and emits light in first sub-period and second sub-period.
