Abstract: A display device, an electronic equipment, and a method for driving a display device are disclosed. The display device includes a first light source group, a second light source group, a first image sensor group, and a second image sensor group. The first light source group is configured to emit light of a first determined frequency to illuminate a first partial region of a detection object, the second light source group is configured to emit light of a second determined frequency to illuminate a second partial region of the detection object, the first image sensor group is configured to receive the light of the first determined frequency emitted by the first light source group and reflected by the detection object, and the second image sensor group is configured to receive the light of the second determined frequency emitted by the second light source group and reflected by the detection object.

Abstract: A light source module and a display module are provided. The light source module includes: a substrate; a plurality of first light sources spaced on the substrate, each of the plurality of first light sources being configured to emit visible light; a depth sensor on the substrate; and a first blocking member configured to shield visible light but transmit invisible light. The depth sensor includes a second light source configured to emit invisible light and a light receiving member configured to sense invisible light, an orthographic projection of the second light source on the substrate is located within an orthographic projection of a gap between two adjacent first light sources on the substrate, an orthographic projection of the first blocking member on the substrate at least partially covers the orthographic projection of the second light source on the substrate.

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.
