1. A device, comprising:
a touch-mode biometric sensor having a first side facing toward a user and a second side opposite to the first side;
a display arranged under the touch-mode biometric sensor, adjacent to the second side and configured to display an image in response to a sensing result, associated with a biometric feature of the user, of the touch-mode biometric sensor;
a frame disposed over the display and configured to conduct an electric current associated with a touch event to a finger of the user, wherein the frame comprises a bevel portion that overlaps a periphery of the display from a top-view perspective;
a first circuit board laterally surrounding the touch-mode biometric sensor, wherein the first circuit board comprises a sidewall and an upper surface adjacent to the sidewall, the sidewall of the first circuit board is in contact with the touch-mode biometric sensor, and the upper surface of the first circuit board is in contact with the frame;
a second circuit board supporting the display;
a third circuit board arranged under the second circuit board; and
a conductive pillar penetrating the first circuit board, the second circuit board, and the third circuit board to secure the first circuit board, the second circuit board, and the third circuit board, wherein the conductive pillar is configured to transmit an electrical signal from the third circuit board to the frame through the first circuit board,
wherein the image associated with the sensing result is overlapped with the finger during the touch event from the top-view perspective, and the touch event is configured to authenticate the user through recognizing a biometric pattern of the user.
