Abstract
The invention relates to a fingerprint identification structure, which comprises a plurality of point light sources and a substrate, wherein the plurality of point light sources are used for emittingsignal light; the substrate is located on the backlight side of the point light sources, a plurality of photosensitive induction units are arranged on the side, which deviates from the point light sources, of the substrate, and the photosensitive induction units are used for receiving the signal light reflected by the fingerprint of the finger so as to identify the fingerprint. The invention further relates to a fingerprint identification display substrate and a manufacturing method thereof. The photosensitive induction units are arranged on the side, which deviates from the point light sources, of the substrate, the distance between the photosensitive induction units and a finger touch interface is increased, and the magnification of the fingerprint image is increased, so that an invalidarea in the fingerprint image formed by lightening one point light source is covered by an image area in the fingerprint image formed when the point light source adjacent to the point light source islightened, and the fingerprint identification effect is improved.
Description
technical field [0001] The invention relates to the technical field of manufacturing touch products, in particular to a fingerprint recognition structure, a fingerprint recognition display substrate and a manufacturing method thereof. Background technique [0002] When the fingerprint identification device collects fingerprints, due to the characteristics of the photosensitive element, the formed image includes image areas and invalid areas, which leads to inaccurate collected fingerprints and reduces the fingerprint identification effect. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a fingerprint recognition structure, a fingerprint recognition display substrate and a manufacturing method thereof, which solve the problems of inaccurate collected fingerprints and poor fingerprint recognition effect. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: ...
