Abstract: Provided are a combined fingerprint recognition touch sensor, an electronic apparatus including the same, and a fingerprint enrollment method to which the same is applied. The combined fingerprint recognition touch sensor includes parallel transmission lines extending in a touch sensing region, and a plurality of parallel reception lines extending in the touch sensing region to intersect the transmission lines. A signal transmitter includes a plurality of transmission groups so as to apply driving signals to the transmission lines. A storage is configured to store an enrolled fingerprint image to be compared with an enrolled fingerprint for fingerprint authentication. In the fingerprint enrollment mode, a fingerprint image of a finger is obtained through one touch operation by applying driving signals to transmission lines belonging to two or more transmission groups and reading a fingerprint image of a sensing zone including an initial touch region and a surrounding region.

Abstract: Disclosed is a method of driving a radiation detection apparatus using a variable voltage applying scheme. In the method, different voltages are applied in a standby step, where radiation is not irradiated onto the radiation detection apparatus, and an irradiation step where the radiation is irradiated. A voltage which is applied in the standby step has an absolute value lower than a voltage which is applied in the irradiation step, and is set to minimize a dark current which is generated in a photoconductor layer of the radiation detection apparatus in the standby step.
