Problems solved by technology

And because the capacitive fingerprint recognition technology judges the valley and ridge of the fingerprint by detecting the capacitance, so as to carry out fingerprint recognition, therefore, when the finger is wet, it is easy to cause recognition error or malfunction.
For mobile phones using optical fingerprint recognition technology, an additional image acquisition unit is required for image acquisition, which will increase production costs

Embodiment Construction

[0025] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0026] The invention provides a fingerprint identification device, which combines figure 1 with figure 2 As shown, the fingerprint identification device camera module 20 , light emitting module 30 and optical waveguide module 40 , the camera module 20 includes structures such as a lighting lens 21 , a prism group 22 and a photosensitive device 23 . The optical waveguide module 40 has a light incident surface. The light-emitting module 30 emits light toward the outside of the fingerprint identification device, and at least a part of the light from the light-emitting module 30 can be reflected by the fingerprint on the light-emitting side of the light-emitting ...

Abstract

The invention provides a fingerprint recognition device. The fingerprint recognition device comprises a camera module, a light emitting module and an optical waveguide module, wherein the camera module comprises a lighting lens; the optical waveguide module comprises a light-in surface; the light emitting module emits light toward the outer part of the fingerprint recognition device; at least a part of the light of the light emitting module can be reflected to the light-in surface of the optical waveguide module by a fingerprint at a light-out side of the light emitting module; and the opticalwaveguide module is used for carrying out total reflection on the light on the light-in surface for multiple times so as to enable the light to irradiate to the lighting camera. Correspondingly, theinvention provides display equipment. During fingerprint recognition, the display equipment is capable of preventing the problem of mis-recognition caused by fingerprint water touch and then controlling the generation cost.

Description

technical field [0001] The invention relates to the field of smart devices, in particular to a fingerprint identification device and a display device. Background technique [0002] Fingerprint recognition technology has been widely used in many fields, and devices such as mobile phones used in daily life are increasingly integrated with fingerprint recognition functions. At present, capacitive fingerprint recognition technology is mostly used on mobile phones, and a capacitive fingerprint recognition structure is integrated on the back of the mobile phone or the main key (Home key). Since the capacitive fingerprint recognition technology detects the valleys and ridges of the fingerprint by detecting the capacitance, and then performs fingerprint recognition, when the finger gets wet, it is easy to cause recognition errors or failures. However, for mobile phones utilizing optical fingerprint recognition technology, additional image acquisition units need to be provided for i...
