Abstract: The present invention relates to a biometric imaging arrangement configured to be arranged under an at least partly transparent display panel and to acquire an infrared image of an object located on the opposite side of the least partly transparent display panel, the biometric imaging arrangement comprising: an image sensor comprising a detector pixel array configured to detect infrared light transmitted from the object for capturing an image, an at least partly transparent substrate comprising an array of microlenses, wherein each microlens is configured to redirect light through the least partly transparent substrate and onto the detector pixel array, wherein the at least partly transparent substrate further comprises optical decoupling areas configured to orthogonally redirect infrared light received from a side of the at least partly transparent substrate towards the object when being placed for imaging.

Abstract: In an aspect, a fingerprint sensing module configured to be integrated in a device for biometric authentication of a user of the device is provided. The fingerprint sensing module comprises a fingerprint sensor and a display configured to display information to the user; the display comprising pixel elements being arranged in the display such that the pixel elements do not obscure a sensing area of the fingerprint sensor in which area the fingerprint sensor is being configured to detect a finger of the user.
