The invention discloses a display device and a driving method of the display device, and belongs to the technical field of display. The display device comprises a display panel, a display area of the display panel is provided with multiple photosensitive sensors at intervals, a light output side of the display panel is provided with at least one auxiliary panel, the auxiliary panels can form multiple photic areas arranged at intervals, the spacings among the multiple photic areas forms a shade area, and light emitted by an object located above the auxiliary panel can form an image of the object on the photosensitive sensor through the photic area. According to the display device, there is no need to independently set a recognition area for an object recognition (finger recognition) module, object recognition can be achieved directly at the display area of the display device, thus narrow border design can be achieved, and the cost is saved. Meanwhile, when the photic area is utilized to image, light outwards emitted around an object area can be absorbed by the shade area, therefore interference light can be reduced, and thus the accuracy of the object recognition can be improved.
