Description

technical field

The utility model relates to the field of fingerprint identification, in particular to a fingerprint identification device, a touch screen and terminal equipment provided with the device.

Background technique

With the development of science and technology, the application of portable terminal devices in people's daily life is becoming more and more extensive, and their functions are becoming more and more powerful. But while the portable terminal device has more and more functions, it also carries a lot of private information. If these private information are leaked or stolen, it will bring inconvenience to the user and cause immeasurable losses. Therefore, it is very necessary to set up a security structure on the portable terminal.

Then, for encryption using passwords and other methods, the user needs to remember the preset password, and there is also the possibility of the password being leaked or cracked. Human fingerprints are formed by the interaction of genetics and the environment, and their complexity can not only provide enough for identification, but also have uniqueness and invariance. Therefore, fingerprint identification has become an encryption method used by some electronic devices.

However, for a terminal device equipped with a fingerprint identification device, the fingerprint identification module needs to be installed under the cover. As the user's input interface, the cover plate needs certain strength, so the thickness of the cover plate is often greater than 300 microns. Although the increase in the thickness of the cover plate increases the strength of the cover plate, it also affects the recognition efficiency of the fingerprint identification module for fingerprints.

In order to realize the fingerprint identification function and meet the thickness requirements of the cover plate, the existing electronic products usually use LGA (Land Grid Array, grid array packaging) packaging technology to open through holes on the surface of the cover plate to expose the touch sensing area of the fingerprint sensor , so that the fingerprint sensor can perform fingerprint detection. However, if this method is adopted, the strength of the cover plate cannot be guaranteed, and the cover plate is easily damaged. The cover plate is generally made of glass, and the glass is more likely to break when cutting to form through holes, resulting in a lower yield rate, lower production efficiency, and increased production costs.

In order to facilitate the understanding of the utility model, the utility model will be described more fully below with reference to the relevant drawings. Preferred embodiments of the present utility model are provided in the accompanying drawings. However, the invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present utility model more thorough and comprehensive.

It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of this invention. The terminology used in the description of the utility model herein is only for the purpose of describing specific embodiments, and is not intended to limit the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in FIG. 1 , FIG. 2 , FIG. 3 and FIG. 4 , a fingerprint identification device 100 in this preferred embodiment includes a cover element 120 and a fingerprint identification module 140 .

The cover element 120 includes a first surface 122 and a second surface 124 parallel to each other, and the second surface 124 defines a groove 126 .

The fingerprint recognition module 140 includes at least one fingerprint sensor 142 configured to sense a fingerprint of a user's finger. One end of the fingerprint sensor 142 for sensing fingerprints is disposed in the groove 126 for sensing fingerprints on the first surface 124 .

The above-mentioned fingerprint identification device 100, the second surface 124 is provided with a groove 126, and the fingerprint identification module 140 is partially installed in the groove 126, thus reducing the distance for the fingerprint identification module 140 to sense fingerprints and improving the sensitivity of the fingerprint identification module 140. Accuracy and accuracy, it is easier to recognize the fingerprint on the first surface 122. At the same time, the thickness of the area not provided with the groove 126 is thicker, which ensures that the cover plate element 120 has sufficient strength and is not easily damaged.

When the fingerprint identification device 100 is installed on a terminal device such as a mobile phone or a computer, the cover element 120 is located on the outermost layer to protect the internal components of the terminal device, and the user can complete various functions of the terminal device by touching the cover element 120. touch operation. Moreover, the first surface 122 is located on the side facing outward of the fingerprint recognition device 100 , and the second surface 124 is on the side facing the interior of terminal equipment such as mobile phones and computers, that is, the side closer to electronic components. Since the groove 126 is disposed on the second surface 124, the overall flatness of the first surface 122 can be ensured, so the appearance is more beautiful.

The cover element 120 is made of transparent and/or non-transparent materials, specifically, any one of tempered glass, toughened glass, polycarbonate, sapphire, and ceramics can be used. Preferably, it can be made of high-strength materials to effectively protect various elements located on the second surface 124 side. For example, the Moore hardness value of sapphire is 9, second only to that of diamond, so the second surface 124 of the cover element 120 will not be scratched by sand.

Since the cover element 120 is used as the user's input interface, it will often accept the user's touch and press and other usage behaviors, and it will come into contact with other objects or even collide with other objects during use. Therefore, the cover member 120 needs to achieve a certain strength. The thickness of the area of the cover element 120 not provided with the groove 126 is 300-400 microns, which can ensure the strength of the cover element 120 .

In this way, the overall thickness of the cover element 120 of the electronic device is below 500 microns, so that the cover element 120 of the electronic device can not only meet the requirements of the rigidity of the input interface, but also not increase the thickness of the electronic device. Without digging holes, the fingerprint sensor 142 is cleverly embedded in the cover element 120 to solve the technical problem of the present invention.

The thickness of the area where the groove 126 is opened on the cover element 120 is less than 150 microns, so as to ensure that the fingerprint sensor 142 can identify the fingerprint.

The fixing surface is recessed inwardly relative to the second surface 124 , and the guiding surface extends from the second surface 124 toward the first surface 122 and surrounds the fixing surface. The guiding surface connects the second surface 124 and the fixing surface, and surrounds the fixing surface. In this way, the fingerprint sensor 142 can be easily positioned in the groove 126 .

The guide surface extends obliquely from the second surface 124 toward the fixed surface, so that the cross-sectional diameter of the groove 126 gradually decreases from the second surface 124 toward the fixed surface, so that the fingerprint recognition module 140 is installed in the groove 126, And through the groove 126 for accurate positioning. In this way, the smooth transition between the fixing surface and the first surface 122 ensures the strength of the cover element 120 and makes the edge of the groove 126 less likely to be damaged. The overall shape of the groove 126 can be circular, square or other regular shapes, or irregular, as long as it can accommodate the fingerprint sensor 142 .

Press the cover element 120 in the area corresponding to the first surface 122 and the fingerprint recognition module 140, and the fingerprint recognition module 140 can collect fingerprint information and output a signal.

The fingerprint recognition module 140 includes a fingerprint sensor 142 , a fingerprint recognition chip 144 and a circuit substrate 146 . The fingerprint sensor 142 is electrically connected to the fingerprint identification chip 144 through a circuit substrate 146 . Fingerprint sensor 142 includes a set of capacitive elements configured to sense a fingerprint by capacitively coupling to the ridges of the fingerprint.

Specifically, the fingerprint sensor 142 includes a plurality of fingerprint recognition units arranged in a matrix. The fingerprint identification unit may include sensing electrodes and driving electrodes. There is a detection gap between the sensing electrode and the driving electrode, which can constitute a basic capacitor. When the finger presses the position corresponding to the fingerprint identification module 140 on the first surface 122, since the dielectric constant of the fingerprint ridge is 10 to 20 times that of air, the sensing The capacitive coupling between the electrodes and the drive electrodes changes differently depending on whether the fingerprint ridges or the fingerprint valleys are located above the detection gap. In this way, the fingerprint ridges and fingerprint valleys are determined, and a fingerprint image is obtained for fingerprint collection and identification.

It can be understood that the working principle of the fingerprint sensor 142 is not limited to this, and optical fingerprint sensors, piezoresistive fingerprint sensors and radio frequency fingerprint sensors can be used, and different types can be selected according to needs.

Further, the fingerprint sensor 142 is electrically connected to the circuit substrate 146 through wires, and the circuit substrate 146 is electrically connected to the fingerprint identification chip 144 . In this embodiment, the fingerprint recognition chip 144 can be installed on the circuit substrate 146 through conductive glue, so as to be electrically connected with the circuit substrate 146 .

It can be understood that the electrical connection between the fingerprint sensor 142 and the circuit substrate 146, and between the circuit substrate 146 and the fingerprint identification chip 144 is not limited to this, as long as the fingerprint sensor 142 is electrically connected to the fingerprint identification chip 144, so that the chip receives and process the fingerprint data collected by the fingerprint sensor 142 .

In this embodiment, the circuit substrate 146 is a flexible circuit board. The flexible circuit board is a kind of highly reliable and better flexible printed circuit board made of polyimide or polyester film as the base material. It has the characteristics of high wiring density, light weight, thin thickness and good bendability. The application of the flexible circuit board in the fingerprint recognition module 140 can reduce the size of the fingerprint recognition module 140 , have lighter weight, and have a longer service life.

The fingerprint identification device 100 also includes at least one ink layer 160 . The ink layer 160 covers the second surface 124 and extends to the guiding surface to surround the fingerprint identification module 140 . Specifically, the ink layer 160 can be white, black or other colors, and can be printed on the cover element 120 through a stamp printing process.

In this embodiment, the ink layer 160 is more than two layers. In this way, the electronic components under the cover element 120 can be shaded, so that the color of this area is consistent with other areas. The ink layers of different colors on the guide surface can make it easier for the user to identify the area where the fingerprint identification module 140 is located, improving the speed and accuracy of fingerprint identification.

In other embodiments, the ink layer 160 may not be provided as required, and the cover element 120 is provided in a transparent shape. When the cover element 120 is made of non-transparent material, the ink layer 160 can also be omitted.

In the above-mentioned fingerprint identification device 100, the fingerprint identification module 140 is arranged in the groove 126 of the cover plate element 120, which can reduce the distance between the fingerprint sensor 142 and the fingerprint on the first surface 122, and make the distance less than 200 microns, so that the fingerprint can be detected quickly and accurately. is identified by the fingerprint module 140, which is convenient for the user to operate. Moreover, the cover element 120 does not need to open a through hole, but only needs to open the groove 126 on the second surface 124 , which ensures the strength of the cover element 120 and is not easy to be damaged, and prolongs the service life of the fingerprint identification device 100 .

As shown in FIG. 6 , the second embodiment of the present invention provides a fingerprint identification device 200 . The structure of the fingerprint identification device 200 is substantially the same as that of the above-mentioned fingerprint identification device 100 , including a cover element 220 and a fingerprint identification module 240 .

The cover element 220 includes a first surface 222 and a second surface 224 arranged in parallel, and the second surface 224 defines a groove 226 . The groove 226 includes a guiding surface and a fixing surface (not shown). The fingerprint identification module 240 includes a fingerprint sensor 242, a fingerprint identification chip and a circuit substrate.

The difference of this embodiment is that, in this embodiment, the color of the ink layer 260 disposed on the guide surface and other regions of the second surface 224 is different. In this way, the user can quickly locate the location of the fingerprint sensor 242 by distinguishing the color, thereby improving the speed and accuracy of fingerprint recognition.
