The invention provides a chip, a module and an electronic device. The chip comprises a third surface and a fourth surface in opposite arrangement, wherein a light sensing region is formed in the thirdsurface and is used for imaging light shot in a shooting module; a fingerprint recognition integration circuit is arranged on the fourth surface and is used for receiving a touch signal in the fingerprint recognition module and executing the corresponding operation. The light sensing chip and the fingerprint recognition integrated circuit are integrally arranged on the two surfaces of one chip, so that one chip realizes the two functions; the use of one chip can be further reduced; the manufacturing cost of the chip is reduced. Meanwhile, in the installation process, only one chip can be installed. Compared with the condition of the need of two chips in the prior art, the invention has the advantages that the installation cost of one chip can be reduced, so that the production cost of thechip is reduced.
