Electronic device

An electronic device, comprising:

• a window;
• a display module;
• a fingerprint sensing layer disposed at a lower part of the window;
• a touch sensing layer having a specific area disposed between the fingerprint sensing layer and the display module, and a remaining area disposed between the window and the display module;
• a first circuit board connected to the fingerprint sensing layer to process fingerprint information;
• a second circuit board connected to the touch sensing layer to process a touch input;
• and
• a controller,
• wherein the touch sensing layer includes a plurality of Rx electrode lines and a plurality of Tx electrode lines,
• wherein the fingerprint sensing layer includes a plurality of Tx electrode lines and a plurality of Rx electrode lines,
• wherein the plurality of Rx electrode lines of the fingerprint sensing layer includes first Rx electrode lines overlapping part of the plurality of Rx electrode lines of the touch sensing layer, and second Rx electrode lines which are remaining electrode lines of the plurality of Rx electrode lines,
• wherein each of the plurality of Rx electrode lines of the fingerprint sensing layer further includes a switch unit so as to be connected to the first circuit board, and
• wherein the controller controls the switch unit such that the first Rx electrode lines are connected to the second circuit board, and the second Rx electrode lines are disconnected from the second circuit board while the touch input is being sensed.

An electronic device, comprising:

• a touch screen including a display area for displaying an image,
• a window disposed above the touch screen, and
• a controller,
• wherein the touch screen comprises:
• a touch sensing layer for receiving a touch input applied to the display area and receiving the touch input at a first sensing resolution;
• and
• a fingerprint sensing layer overlapping a specific area of the display area and disposed between the window and the touch sensing layer, and configured to sense a fingerprint at a second sensing resolution, which is higher than the first sensing resolution, when a finger is touched on the specific area, and
• wherein the controller controls the fingerprint sensing layer so that the second sensing resolution of the specific area is changed to the first sensing resolution in order to receive a touch input of a finger making contact with the specific area based on a specific control command.
