Embodiment Construction

[0048] When light is incident on a surface of an object, the ups and downs of the surface will cause different reflected light. The image sensing device provided by the present invention recognizes the object image based on the above principles. For example, since a fingerprint has ridges (or ridges) and grooves, the present invention The provided image sensing device can identify fingerprints through the light reflected by the finger, that is, the image sensing device provided by the present invention can be applied to fingerprint recognition / identification / fingerprint authentication . For the sake of brevity, the following uses a fingerprint image sensing device as an example. However, those skilled in the art should understand that the application of the present invention is not limited thereto.

[0049] see figure 1 , which is a schematic diagram of an embodiment of the image sensing device of the present invention. In this embodiment, the image sensing device 100 can b...

Abstract

An image sensing apparatus includes a substrate, a light guide plate, a plurality of photosensors and a light source. The substrate has a first side. The light guide plate has a light exit surface and a light entry surface, wherein the light exit surface faces the first side of the substrate. The photosensors are disposed on the first side of the substrate. The light source is disposed near the light entry surface of the light guide plate, wherein light generated from the light source enters the light guide plate through the light entry surface. After entering the light guide plate, the light generated from the light source is incident to the substrate through the light exit surface of the light guide plate, or travels in the light guide plate by total internal reflection.

Description

technical field [0001] The invention relates to image sensing, in particular to an image sensing device for fingerprint recognition by detecting reflected light. Background technique [0002] Due to the popularity of personal mobile devices (eg, smart phones), many users use their mobile devices to use related services that require personal data, such as e-commerce transactions and member data management. In order to ensure the security of the transaction, the service provider will provide relevant user services after confirming the user's personal data provided by the client (for example, entering the user name and account password). However, such authorization verification methods have Risk of fraudulent use by others. [0003] Therefore, there is an urgent need for an authorization verification mechanism with high security to ensure the rights and interests of users. Contents of the invention [0004] In view of this, one of the objectives of the present invention is ...
