Electronic device supporting fingerprint verification and method for operating the same

An electronic device, comprising:

• a display in which a fingerprint recognition area is formed in at least one portion thereof and which includes a display pixel layer;
• a rear panel, formed under the display, comprising a first hole aligned with a portion of the display pixel layer;
• a bracket, disposed under the rear panel to support the display, comprising a sensor accommodating area aligned with the portion of the display pixel layer and having a size corresponding to a fingerprint sensor;
• the fingerprint sensor disposed under the display pixel layer and adapted to acquire image information to be used for authentication of a fingerprint corresponding to an object that approaches the fingerprint recognition area using, at least partially, light radiated from the display pixel layer and reflected by the object;
• and
• a processor adapted to display, on the display, the fingerprint recognition area when a function associated with a fingerprint recognition is executed,
• wherein the sensor accommodating area in the bracket has a second hole passing through the bracket, and the fingerprint sensor is disposed in the sensor accommodating area such that an air gap between the display and the fingerprint sensor is formed at least by a portion of the second hole.
