    Abstract: The present disclosure relates to an electronic device with a display device having enhanced display power consumption. The electronic device includes: a housing; a transparent member disposed in at least a portion of the housing, and includes an upper surface and a lower surface; a first anti-reflection layer coupled to the upper surface of the transparent member; and a display panel coupled to at least a portion of the lower surface of the transparent member by a visually transparent adhesive member, and housed in the housing. The display panel includes: a polarizing film layer coupled to the adhesive member and including an upper surface and lower surface; a light emitting layer disposed under the lower surface of the polarizing film layer; and a second anti-reflection layer disposed on the lower surface of the polarizing film layer between the lower surface of the polarizing film layer and the light emitting layer.

    Abstract: Disclosed is an electronic device that includes a housing including a first plate facing a first direction, the first plate including a fingerprint sensing area, a second plate facing a second direction opposite to the first direction, and a side member interposed between the first and second plates, a touch screen display interposed between the first and second plates and having at least a portion exposed through the first plate of the housing, a fingerprint sensor interposed between the touch screen display and the second plate, and a processor connected to the fingerprint sensor. The processor may determine whether the fingerprint sensing area is contaminated and determine whether to register a fingerprint image captured by the fingerprint sensor based on whether the fingerprint sensing area is contaminated. In addition, it is possible to implement other various embodiment understood through the disclosure.

    Abstract: Provided are an electronic device and operation method thereof. The electronic device may include: a display having a biometric sensing region; a biometric sensor disposed in the biometric sensing region; and a processor. The processor may be configured to: operate a first sub-region of the biometric sensing region according to a first display attribute and operate a second sub-region of the biometric sensing region according to a second display attribute; while the first sub-region is operated according to the first display attribute and the second sub-region is operated according to the second display attribute, obtain, through the biometric sensor, a signal corresponding to an external object, wherein the signal is generated at least partially based on light that is emitted from the first sub-region or the second sub-region and reflected by the external object; perform authentication on the external object if the signal satisfies a specified condition; and prevent authentication on the external object if the signal does not satisfy the specified condition.
