1. A display device, wherein the display device comprises:
a flexible display panel comprising a display region and a peripheral region surrounding the display region, wherein the display region comprises a slidable region and a fixed region;
a driver integrated circuit (IC) disposed in the peripheral region;
a plurality of detection circuits disposed in the peripheral region and close to the slidable region;
at least one input signal line, wherein one end of the at least one input signal line is electrically connected to the driver IC and the other end of the at least one input signal line is electrically connected to the plurality of detection circuits;
at least one control signal line, wherein one end of the at least one control signal line is electrically connected to the driver IC and the other end of the at least one control signal line is electrically connected to the plurality of detection circuits; and
at least one detection signal line, wherein one end of the at least one detection signal line is electrically connected to the driver IC and the other end of the at least one detection signal line is electrically connected to the plurality of detection circuits;
wherein each of the plurality of detection circuits is turned off under control of a control signal provided by the at least one control signal line, and is configured to transmit a detection current to the at least one detection signal line based on an input signal provided by the at least one input signal line when detecting external ambient light; the driver IC stores a corresponding relationship between a current range and a length of an effective display region in a first direction, wherein the effective display region comprises the fixed region and an expanded region of the slidable region, and the first direction is an arrangement direction of the slidable region and the fixed region; the driver IC is configured to determine the length of the effective display region of the flexible display panel in the first direction based on a magnitude of the detection current in the at least one detection signal line and the corresponding relationship and control the effective display region to display an image based on the length of the effective display region.
