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.
