1. An electronic device comprising:
a device housing having a front side and a back side;
a front fingerprint scanner exposed at the front side of the device housing at a front fingerprint scanner location;
a back fingerprint scanner exposed at the back side of the device housing;
a blade assembly having a blade slidably coupled to the device housing and having a flexible display attached to the blade, the blade assembly having first and second fingerprint-on-display areas that are optically transmissive, enabling light from corresponding ones of the front and the back fingerprint scanner to pass through the blade assembly; and
a translation mechanism operable to slide the blade assembly relative to the device housing between a fully retracted position and a fully extended position, wherein in the fully retracted position the first and the second fingerprint-on-display areas are respectively positioned above the front fingerprint scanner and the back fingerprint scanner.
