Abstract: A method for imaging a fingerprint under a screen, including: acquiring a finger pressing area formed by a finger pressing on the screen; determining a first light source and a second light source of the screen based on the finger pressing area, wherein arrangement directions of the first light source and the second light source are not perpendicular to a long axis of the finger pressing area; acquiring a first fingerprint image after the first light source is turned on, and a second fingerprint image after the second light source is turned on; and splicing the first fingerprint image and the second fingerprint image to acquire a target fingerprint image.

Abstract: A display panel is disclosed. The display panel includes a back plate, a plurality of pixel units formed on the back plate, and a plurality of deformation units for providing haptic feedback. Each deformation unit is on one or more corresponding pixel units of the plurality of pixel units, and when being applied a drive voltage, undergoes a deformation corresponding to a haptic feature of a visual object displayed by the corresponding pixel units. Thereby, there is provided a display panel with haptic feedback, which is simple in structure and easy to implement.
