Embodiment 1

[0040] According to an embodiment of the present invention, an embodiment of a fingerprint detection device is provided, image 3 is a side view of a fingerprint detection device according to an embodiment of the present application, such as image 3 As shown, the device includes:

[0041] The glass cover 10 is used for touch operation bearing fingerprints.

[0042] At least one set of detection equipment, wherein at least one set of detection equipment includes:

[0043] The light source 20 is disposed on one side of the glass cover 10 for emitting detection light, wherein the detection light enters the glass cover from one side.

[0044] Specifically, when the detection light emitted by the above-mentioned light source 20 passes through one side of the cover glass 10 and irradiates the upper surface of the cover glass, if a certain part of the upper surface of the cover glass contacts the fingerprint valley 51, the light will pass through the cover through multiple total r...

Embodiment 2

[0061] According to an embodiment of the present invention, an embodiment of a detection method of a fingerprint detection device is provided. The horizontal resolution of the photosensitive array of the fingerprint detection device is greater than the vertical resolution. It should be noted that the flow chart shown in the accompanying drawings The steps may be performed in a computer system, such as a set of computer-executable instructions, and, although a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different from that shown or described herein. A step of.

[0062] Figure 10 It is a flow chart of the detection method of the fingerprint detection device according to the embodiment of the present invention. The detection method of the fingerprint detection device proposed in this embodiment can be applied to the fingerprint detection device proposed in Embodiment 1, such as Figure 10 As shown, the me...

Abstract

The invention discloses a fingerprint detecting device and a detecting method thereof, a touch screen and an electronic device. The device comprises: a glass cover plate for bearing touch operation offingerprints; at least one group of detection devices, wherein at least one group of detection devices comprises a light source which is arranged at one side of the glass cover plate and used for emitting detection light rays and the detection light rays enter the glass cover plate from one side; a lens which is arranged between a photosensitive array and the other side of the glass cover plate and used for converging the detection light rays reflected by the glass cover plate to obtain converged light; and the photosensitive array which is arranged at the other side of the glass cover plateand used for determining the image information of the fingerprints according to the converged light, wherein the horizontal resolution of the photosensitive array is greater than the longitudinal resolution of the photosensitive array. By means of the device disclosed by the invention, the technical problem of poor fingerprint recognizing effect in conventional under-the-screen fingerprint recognizing techniques is solved.

Description

technical field [0001] The invention relates to the field of fingerprint identification, in particular to a fingerprint detection device and a detection method thereof, a touch screen and electronic equipment. Background technique [0002] With the development of mobile phone technology, full screen has become a major trend in the development of smart terminals. However, for the traditional capacitive fingerprint recognition technology, it is difficult to complete the task of removing the main control key (Home key) due to many limitations such as capacitive detection cannot penetrate thicker glass. [0003] figure 1 It is a schematic diagram of fingerprint recognition under the screen, combined with figure 1 As shown, using the optical fingerprint identification technology, the fingerprint identification module is placed under the screen, so as to realize optical fingerprint identification for fingerprints in a specific area. But this method requires the display screen t...
