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.
