Embodiment Construction

[0076] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0077] Most of the existing optical imaging structures adopt the optical lens structure. In order to meet the requirements of the lens structure and the optical path, there is an optical lens 3 alignment above each photosensitive sensing unit in the photosensitive sensor array, which requires the photosensitive sensing unit It has extremely high precision alignment with the optical lens. In order to achieve the above-mentioned accuracy, in general implementation schemes, the photosensitive sensing unit and the optical le...

Abstract

The invention provides an optical fingerprint identification device and a preparation method thereof, and a touch terminal, relates to the technical field of display terminals, and aims to alleviate the technical problem of high process complexity of an existing touch terminal with a fingerprint identification function. The optical fingerprint identification device is used for being installed at the bottom of an OLED display device. The optical fingerprint identification device comprises a photosensitive sensor array and an optical film layer. The optical film layer is arranged above the photosensitive sensor array. A optical signal which is emitted from the direction of the OLED display device in a preset angle range passes through the optical film layer and then is emitted into the photosensitive sensor array.

Description

technical field [0001] The present invention relates to the technical field of display terminals, in particular to an optical fingerprint identification device, a preparation method thereof, and a touch terminal. Background technique [0002] Full-screen is the mainstream configuration of current mobile phones, and the use of full-screen mobile phones has also made Organic Light-Emitting Diode (OLED) under-screen fingerprints a popular research direction. like figure 1 As shown, its basic structure is that a fingerprint recognition component 2 is placed under the OLED panel 1, and the fingerprint recognition component 2 includes two parts, an integrated optical imaging structure and an image sensor array. [0003] In current products, most of the optical imaging structure adopts an optical lens (lens) structure. In order to meet the requirements of the lens structure and the optical path, an optical lens 3 is arranged on the top of each photosensitive sensing unit 4 in the ...
