Abstract
An optical fingerprint sensing module attached to a base is provided. The base includes a first surface, a second surface and an opening extending through the first surface and the second surface. The optical fingerprint sensing module includes a fixing frame and a sensor integrated circuit (IC). The fixing frame is disposed in the opening of the base. The sensor IC is disposed in a receiving groove of the fixing frame and includes a plurality of photo sensors. The photo sensors receive light reflected from a user's finger through the opening of the base.
