Embodiment Construction

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0040] It should be pointed out that in the drawings, for clarity of illustration, the dimensions of layers and regions may be exaggerated. Also it will be understood that when an element or layer is referred to as being "on" another element or layer, it can be directly on the other element or intervening layers may be present. Further, it will b...

Abstract

The invention provides a fingerprint identification sensing apparatus and a manufacturing method thereof, and a terminal device. The fingerprint identification sensing apparatus comprises: a substrate which comprises a first surface and a second surface opposite to the first surface, wherein the first surface of the substrate is provided with a groove; a first conductor layer disposed on the bottom surface of the groove; a protective layer which is disposed in the groove and covers the first conductor layer; a second conductor layer disposed on the second surface, wherein the first conductor layer and the second conductor layer form two electrodes of a capacitor for transmitting radiofrequency signals; and a radiofrequency field induction module disposed at one side of the second surface of the substrate. According to the invention, the problem in the prior art that fingerprint identification is realized by arranging through holes and the problem that a part of a conductive material, higher than a transparent cover plate, is easily worn and corroded during application can be solved.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a fingerprint identification sensing device, a manufacturing method thereof, and a terminal device. Background technique [0002] In existing terminal equipment, the introduction of RFID (Radio Frequency Identification, radio frequency identification) technology provides a new option for realizing fingerprint identification. For example, a terminal device in the prior art makes a metal ring penetrating through a transparent cover around a physical key, so that a radio frequency signal can be transmitted to a finger touching the key through the metal ring. Thus, the finger constitutes one pole of the capacitor, and the sensor array at the bottom of the key constitutes the other pole of the capacitor, so the distance between the finger surface and the sensor array will vary with the unevenness of the finger surface in various places. Different distances cause different electric fie...
