This publication describes techniques for embedding an under-display fingerprint sensor (UDFPS) system, without increasing the thickness of an electronic device (e.g., smartphone) and/or decreasing the storage capacity of a battery of the smartphone. The described techniques allow a manufacturer to embed the UDFPS system outside the planar footprint of the battery of the smartphone. Also, these techniques enhance user experience by assembling the UDFPS system closer to the bottom edge of the smartphone, may enable the removal of a display flex support (backer), and may decrease the shear stress of a display bend of a display screen of the smartphone, increasing the mechanical strength the display screen.
