Abstract: Various embodiments of the disclosure relate to an electronic device including an under display camera (UDC). The electronic device includes: a housing, a display, and a camera disposed inside the housing overlapping a portion of the display and acquiring light passing through the display from outside. The display includes a first area in which a first pixel overlapping with at least a portion of the camera and a first pixel driving circuit for driving the first pixel are disposed, and a second area, other than the first area, in which a second pixel and a second pixel driving circuit for driving the second pixel are disposed. The first pixel driving circuit includes a first driving thin film transistor (TFT) having a first channel region having a straight shape does not include a curved shape, and the second pixel driving circuit includes a second driving TFT having a second channel region of a curved shape. A first channel width of the first driving TFT is greater than a second channel width of the second driving TFT, and a first channel length of the first driving TFT is less than a second channel length of the second driving TFT.

Abstract: An electronic device is provided. The electronic device includes a display, a display driver integrated circuit (IC) that controls the display, a camera disposed in a display area, and a processor connected with the display driver IC and the camera. The display includes a normal area having a first pixel density, a camera light-receiving area where the camera is disposed and at least one pixel is disposed, the camera light-receiving area having a second pixel density lower than first pixel density, and a circuit area provided between the normal area and the camera light-receiving area and having a third pixel density, and a circuit that transfers a drive voltage to the pixel disposed in the camera light-receiving area is disposed in the circuit area. The third pixel density is lower than or equal to the first pixel density, and the third pixel density is higher than the second pixel density.

Abstract: The present invention is for registering and authenticating biometric data in an electronic device, the electronic device including: a display including a touch sensor; a fingerprint sensor for acquiring fingerprint data through at least a partial region of the display region of the display; and a processor. Here, the processor can be set to: acquire first touch information from a first user input using the touch sensor, in response to the first user input for registering a fingerprint of a user; acquire first fingerprint data using the fingerprint sensor; register the first fingerprint data as fingerprint information based on the first touch information, the registering operation including an operation for classifying the first fingerprint data based on the first touch information; acquire second touch information from a second user input using the touch sensor, in response to the second user input for authenticating the fingerprint of the user; acquire second fingerprint data using the fingerprint sensor; select a candidate group for comparison from among the fingerprint information based on the second touch information; and compare fingerprint data included in the candidate group with the second fingerprint data.
