1. A fingerprint detection array substrate, comprising:
a plurality of touch electrode blocks in a plurality of touch detection regions configured to detect a touch position, wherein a respective one of the plurality of touch electrode blocks extends substantially throughout a subpixel region of a respective subpixel, and is substantially outside an inter-subpixel region of the respective subpixel, touch electrode blocks in a respective one of the plurality of touch detection regions are inter-connected through bridges, forming a touch electrode unit, and the touch electrode unit is isolated from touch electrode blocks in adjacent touch detection regions of the plurality of touch detection regions;
a plurality of touch signal lines configured to respectively transmit touch signals to the plurality of touch detection regions, wherein a respective one of the plurality of touch signal lines is electrically connected to the touch electrode unit limited in the respective one of the plurality of touch detection regions;
a processor configure to determine a fingerprint scanning region comprising one or more touch detection regions in which the touch position is detected; and
a fingerprint sensor configured to perform fingerprint sensing limited in the fingerprint scanning region, wherein an area of the fingerprint scanning region is a fraction of a total area of the plurality of touch detection regions.
