Abstract: A method and device of fingerprint image generation for saving memory. The method includes generating a first fingerprint image of an original data size according to a plurality of first analog sensing signals which are read from a fingerprint sensor array before an exposure period ends. Then the first fingerprint image represented by a first data size which is equivalent to or smaller than the original data size is stored. a second fingerprint image of the original data size is generated after generating the first fingerprint image of the original data size according to a plurality of second analog sensing signals which are read from the fingerprint sensor array during the exposure period. The second fingerprint image represented by a compressed data size smaller than the original data size is then stored.

Abstract: A single-chip device for driving a panel including fingerprint sensing pixels, display pixels and touch sensors, electronic module therefor, and electronic apparatus including the single-chip device are provided. The single-chip device comprises a main body, a first group of pads and a second group of pads disposed in the main body. The main body has a left portion and a right portion with respect to an axis. The first group of pads comprise a plurality of first pads for driving the fingerprint sensing pixels, are disposed on both the left portion and the right portion and configured to be coupled to the fingerprint sensing pixels. The second group of pads comprise a plurality of second pads for driving the display pixels and the touch sensors, are disposed on both the left portion and the right portion and configured to be coupled to the panel.
