This publication describes systems and techniques directed at expediting fingerprint authentication by compensating for display luminance latency. In aspects, a computing device having a display and an under-display fingerprint sensor (UDFPS), includes a local high brightness mode (LHBM) manager configured to selectively adjust luminance settings in a high-luminance region of the display for predetermined intervals. In so doing, user input can be well-illuminated during an initial stage of UDFPS image capturing, facilitating UDFPS sensing and expediting fingerprint authentication.
