    Abstract: The embodiments of the present disclosure provide an optical fingerprint recognition apparatus and a display panel. The apparatus comprises: a light emitting structure (1), a collimating structure (2) and a plurality of photosensitive sensors (3); the light emitting structure (1) is used for generating detecting light; the collimating structure (2) is used for filtering the detecting light reflected by a finger, such that light with a scattering angle in a predetermined range transmits through the collimating structure (2); the photosensitive sensors (3) are used for receiving the light transmitted through the collimating structure (2) and acquiring fingerprint information according to the received light. The embodiments of the present disclosure are used for manufacturing a display panel. The present disclosure can enhance accuracy of the recognized fingerprint information during an optical fingerprint recognition process.

    Abstract: A print recognition module, a method for driving the same, and a display device are disclosed, where a synchronous scan component is added above a sensing surface of a photo sensor array, and the synchronous scan component can be divided into a first light shielding area and a first light transmitting area, both of which are varying dynamically; where the first light transmitting area is formed at least above a photo sensor being scanned to recognize a print, and the first light shielding area can shield the other photo sensors than the photo sensor being scanned to recognize the print, so that these photo sensors will not be illuminated by any light; and as the photo sensors are being scanned, the first light shielding area and the first light transmitting area, in the synchronous scan component are varying in synchronization therewith.
