Abstract

The embodiment of the invention provides an optical fingerprint collector which sequentially comprises an FPGA, a backlight, a sensor and an optical fiber, a filter layer is arranged on the side, close to the optical fiber, of the sensor, and the wavelength of light transmitted through the filter layer is consistent with that of the backlight. According to the optical fingerprint collector, the backlight is arranged behind the sensor and the optical fiber, the light emitted by the backlight reaches the optical fiber after passing through the sensor, the rear filter layer is arranged on the sensor, when the filter layer receives the light incident from the outside, only the light with the wavelength consistent with that of the backlight is allowed to enter the sensor, and no matter how strong the outside light is, the sensor cannot be damaged. The light of the external light reaching the sensor through the finger does not affect the normal fingerprint collection of the sensor, the optical fingerprint collector is not limited to a certain working environment, and the collection result is more accurate.

Description

technical field [0001] The present disclosure relates to the field of displays, in particular to an optical fingerprint collector. Background technique [0002] The uniqueness of fingerprints makes fingerprint imaging widely used. Fingerprint imaging recognition technology is widely used in fingerprint collection, smart devices, fingerprint locks and other fields. The optical fingerprint sensor is a key device to realize fingerprint collection, which converts optical signals into electrical signals to realize fingerprint collection. [0003] The optical fingerprint collector mainly realizes the fingerprint collection by the optical path. Since the optical fingerprint collector will work outdoors, the external strong light is relatively large interference, resulting in inaccurate fingerprint collection results. Contents of the invention [0004] In view of this, the embodiment of the present disclosure proposes an optical fingerprint collector to solve the following proble...
