Abstract
A light guiding structure for fingerprint recognizing sheet is adapted between a circuit board and a protecting sheet for encompassing an image capture device. The light guiding structure includes a frame, side-emitting LEDs, and a light guiding sheet. The middle portion of the frame is defined as a hollowed portion. Conductive pairs are located on the frame and extended out of the frame to form a first contact and a second contact. The side-emitting LEDs are assembled to the frame and electrically connected to the conductive pairs. The light guiding sheet covers on the hollowed portion. The side-emitting LEDs are assembled around the periphery of the light guiding sheet. The light guiding structure can be directly assembled on the circuit board and encompass the image capture device, and therefore an electronic device can be provided with a fingerprint recognizing sheet having the light guiding structure.
