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.

Abstract: A liquid crystal module includes an array substrate, a color film substrate, and a liquid crystal layer. The array substrate and the color film substrate are disposed oppositely. The liquid crystal layer is disposed between the array substrate and the color film substrate. The array substrate includes a pixel electrode and a capacitor metal layer arranged on a side of the pixel electrode away from the liquid crystal layer. The capacitor metal layer and the pixel electrode form a storage capacitor. The color film substrate includes a reset electrode assembly. In a reset period, the reset electrode assembly is configured to access to a reset voltage signal to orient liquid crystal molecules along a first orientation direction. The reset electrode assembly includes an adjustment structure. During the reset period, the adjustment structure is configured to reduce a capacitive reactance load when the reset voltage signal is turned off.
