Problems solved by technology

However, in the process of optical fingerprint recognition, when the distance between the finger and the sensor is large, the sensor may simultaneously receive light reflected by multiple ridges and / or valleys due to the scattering of the light reflected by the finger, resulting in The fingerprint information recognized by the light received by the sensor is inaccurate

Abstract

The embodiment of the invention provides an optical fingerprint identification device and a display panel, relating to the technical field of fingerprint identification. The device and the display panel are used for improving the accuracy of identified fingerprint information in the process of optical fingerprint identification. The device comprises a light emitting structure, a collimating structure, and a plurality of photosensitive sensors. The light emitting structure is used for generating detection light. The collimating structure is used for filtering the detection light reflected by a finger such that a light whose scattering angle in a preset range penetrates the collimating structure. The photosensitive sensors are used for receiving light which penetrates the collimating structure and obtaining the fingerprint information according to received light. The embodiment of the present invention is used for manufacturing the display panel.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to an optical fingerprint identification device and a display panel. Background technique [0002] Fingerprints refer to the uneven lines on the skin on the front of the end of a human finger; among them, the raised positions are called ridges, and the sunken positions are called valleys. Due to its lifelong invariance, uniqueness and convenience, fingerprints have almost become synonymous with biometric identification. [0003] At present, the fingerprint identification device integrated in the display module is generally installed in the non-display area such as the main menu key or the back of the display module, and the display module is developing in the direction of ultra-thin, high color gamut, wide viewing angle, and integration. Therefore, integrating the fingerprint identification device in the display area of ​​the display module to realize optical fin...
