    Abstract: An electrical signal detection module includes a photoelectrical signal application circuitry, an operational amplifier, a gain control circuitry and a master control circuitry. The gain control circuitry includes at least two gain control sub-circuitries connected in parallel to each other, and a discharge switching sub-circuitry connected in parallel to the gain control sub-circuitries. Each gain control sub-circuitry includes a gain switching sub-circuitry and a gain capacitive sub-circuitry connected in series to each other. The master control circuitry is configured to apply a discharge switching signal to the discharge switching sub-circuitry, and apply a gain switching control signal to the corresponding gain switching sub-circuitry. The gain switching sub-circuitry is configured to control a first end and a second end of the gain switching sub-circuitry to be electrically connected to each other in accordance with the gain switching control signal. The discharge switching sub-circuitry is configured to enable a first end of the gain capacitive sub-circuitry connected to the gain switching sub-circuitry to be electrically connected to, or electrically disconnected from, a second end of the gain capacitive sub-circuitry in accordance with the discharge switching signal.

    Abstract: At least one embodiment of this disclosure provides a display apparatus for solving the problem of a low identification precision due to a relatively large distance between the finger and the fingerprint identification device. The display apparatus comprises a display panel and at least one fingerprint identification device. Each fingerprint identification device comprises a plurality of identification units arranged in an array, each identification unit being provided with a photosensitive element. The photosensitive element is used for performing photoelectric conversion of incident light. The fingerprint identification device further comprises a collimating filter layer arranged on a light entrance surface of the photosensitive element. The collimating filter layer comprises a plurality of strip-shaped light guide portions arranged to be spaced and parallel, a longitudinal direction of the plurality of strip-shaped light guide portions being substantially perpendicular to the light entrance surface of the photosensitive element.
