Abstract:
Disclosed are a display panel, a driving method thereof and a display device. The display panel includes: a light-shielding layer including imaging apertures, a light-emitting element layer including first light-emitting elements and second light-emitting elements, a touch functional layer, and a fingerprint recognition module. The orthographic projection of the second light-emitting element on the light-shielding layer is closer to the corresponding imaging aperture than the orthographic projection of the first light-emitting element on the light-shielding layer. In a first detection stage, the first light-emitting elements emit light, the second light-emitting elements do not emit light, and the fingerprint recognition module generates a first fingerprint image. In a second detection stage, the second light-emitting elements emit light, and the fingerprint recognition module generates a second fingerprint image. The first fingerprint image and the second fingerprint image are combined into a fingerprint image.
