Problems solved by technology

However, the metal light-shielding layer will form a large-area metal area on the surface of the glass substrate. When the display panel is pressed, the metal light-shielding layer will generate greater stress, thereby making the glass substrate easily deformed and affecting the subsequent manufacturing process; the metal light-shielding layer is A large-area metal lay

Abstract

The invention relates to the technical field of fingerprint identification, and discloses a fingerprint identification sensor, a manufacturing method thereof and a display device so as to improve theproduct quality of the display device. The fingerprint identification sensor comprises a plurality of fingerprint identification units arranged in an array mode, and is characterized in that each fingerprint identification unit comprises a substrate base plate, an image acquisition device arranged at one side of the substrate base plate and a first grating structure and a second grating structurewhich are sequentially arranged at the other side of the substrate base plate, the first grating structure is provided with a first imaging hole opposite to image acquisition device in position, the second grating structure is provided with a second imaging hole opposite to the image acquisition device in position, and a slit extending direction of the first grating structure is perpendicular to the a slit extending direction of the second grating structure.

Description

Technical field [0001] The present invention relates to the technical field of fingerprint identification, in particular to a fingerprint identification sensor, a manufacturing method thereof, and a display device. Background technique [0002] With the rapid development of e-commerce and e-banking, people have higher and higher requirements for security. How to accurately identify personal identity and protect information security is a key social problem that must be solved in the current information age. Biometric identification uses the inherent physiological characteristics or behavioral characteristics of the human body to perform personal identification, which has high security and is gradually used in people's daily life. Biometric recognition usually includes face recognition, fingerprint recognition, iris recognition, voice recognition, or hand blood vessel distribution recognition.
