Abstract: The present invention comprises: a first region, having a display area for outputting images, for receiving touch input or acquiring fingerprint data by means of a touch entered on the display area; a touchscreen comprising a second region for receiving touch input; and a control unit for switching the first region from a touch receiving mode, which receives touch input, to a fingerprint sensing mode when a touch input is entered in the first region, wherein the touchscreen is provided with a touch sensor layer for receiving touch input at a first sense resolution in the touch receiving mode, and the control unit which, in the fingerprint sensing mode, switches the first region from the first sense resolution to a second sense resolution, which is higher than the former, so as to acquire fingerprint data, and maintains the second region at the first sense resolution so that the former receives touch input.
