Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an input device having a fingerprint sensor and a portable electronic device including the fingerprint sensor,

The present invention relates to an input device having a fingerprint sensor and a portable electronic device including the same.

BACKGROUND ART [0002] Recently, with the public's attention focused on portable electronic devices including smartphones and tablet PCs, research and development on related technical fields are being actively conducted. In many cases, a portable electronic device incorporates a touch screen integrated with a display as a display device as one of input devices for receiving a specific command from a user. The portable electronic device may also include various function keys or soft keys as an input device other than a touch screen.

1 shows a general shape of a smartphone which is a portable electronic device. Referring to FIG. 1, a display unit 1100 is installed on a front surface of a portable electronic device 1000. The display unit 1100 includes a capacitive touch screen. When the user's body (such as a finger) touches the display unit, the display unit 1100 senses a change in capacitance of the built-in capacitor to detect whether the user touches the touch screen.

The capacitive type touch screen is very convenient in that the reaction is immediate, no separate input tool is needed, and multi-touch is possible. However, the user must perform a touch over a predetermined area or pressure on the touch screen Which has a disadvantage in that accurate input is difficult.

To solve this problem, touch screen technology using an electromagnetic pen has been introduced. The electromagnetic pen is also referred to as an Electro-Magnetic Resonance (EMR) pen and has a built-in condenser and a coil inside. A loop coil is disposed on the touch screen. An electromagnetic wave generated by conduction of a current through the loop coil is absorbed by the electromagnetic pen. The electromagnetic pen emits the electromagnetic wave absorbed by the loop at a specific frequency. So that the position of the electromagnetic pen is sensed. The touch screen input method using the electromagnetic pen gives a feeling of a writing instrument familiar to the user and can transmit a more precise sense of touch. Further, even when the user touches the touch screen with his or her hand to use the pen, it becomes possible to selectively recognize only the input of the pen.

Recently, a combined touch screen that can be used for both cases by combining the electrostatic capacity type and the electromagnetic pen type has been developed and commercialized.

A home key 1200 and a function key 1300 for performing various functions such as execution confirmation, execution cancellation, menu display, and reverting may be provided below the portable electronic device 1000. The home key 1200 or the function key 1300 is an input device separate from the display unit 1100 having a touch screen. The input key is theoretically a mechanical switching type key, (Mainly used for the hometown 1200) or a capacitive sensor (mainly a function key 1300) in a mechanical switching mode because of reasons such as limitation of the accommodation space, Use) has been used.

Accordingly, in order for the user to use the function key 1300 while inputting a command to the display unit 1100 in the form of an electromagnetic pen, the user must touch the function key 1300 with a finger other than the electromagnetic pen, .

Meanwhile, since the security of portable electronic devices has become more important in recent years, a form in which a fingerprint sensor is embedded in the home key 1200 has been introduced. The fingerprint sensor is a sensor for detecting fingerprints of a human being. The fingerprint sensor performs user registration or authentication procedures through a fingerprint sensor, thereby protecting the data stored in the portable electronic device and preventing a security accident in advance.

Portable electronic devices also incorporate a navigation function that performs manipulation of a pointer, such as a cursor, into a fingerprint sensor. In addition, a switching function that receives information from a user may be incorporated into the fingerprint sensor.

However, since the hometown key 1200 of the fingerprint sensor type and the function key 1300 of the electrostatic capacity type are separately mounted on the portable electronic device, conventionally, a separate process is required, resulting in process inefficiency and cost increase There was a problem of. In addition, as described above, the function key 1300 is also inconvenient in the user experience when using the electromagnetic pen when the display unit 1100 supports the electromagnetic pen input.

Therefore, it is urgently required to develop an input device incorporating a fingerprint sensor and a portable electronic device including the same, which can solve such a problem.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when a part is referred to as being "connected" to another part, it includes not only "directly connected" but also "indirectly connected" . Also, when an element is referred to as "comprising ", it means that it can include other elements, not excluding other elements unless specifically stated otherwise.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 (a) is a perspective view of an input device for a portable electronic device according to an embodiment of the present invention, and FIG. 2 (b) is a plan view thereof. Here, the portable electronic device includes a portable phone, a smart phone, a PDA, a tablet PC, a notebook computer, a portable sound recorder (MP3 player), and the like.

As shown, the input device 10 includes a base substrate 100, a fingerprint sensor module 200, and a composite sensing sensor 300. Here, the compound sensing sensor 300 is shown as being composed of two sensors 300a and 300b installed on both right and left sides of the fingerprint sensor module 200, but it may be composed of one sensor or three or more sensors. The fingerprint sensor module 200 corresponds to the home key 1200 of the portable electronic device 1000 shown in FIG. 1 and the two hybrid sensing sensors 300a and 300b correspond to the two function keys 1300a And 1300b, respectively.

The fingerprint sensor module 200 is disposed on the base substrate 100 and includes a fingerprint sensor that recognizes the fingerprint of the user. The fingerprint sensor module 200 may further include a dome switch for recognizing pressing of the user's finger.

The composite sensing sensor 300 is located on the base substrate 100 and is spaced apart from the fingerprint sensor module 200 and senses the approach or contact of the conductor and the electromagnetic pen. As described above, the fingerprint sensor module 200 and the complex sensor 300 are integrated on the same base board 100. By mounting the packaged input device on the portable electronic device, And the composite detection sensor 300 are separately mounted on the portable electronic device, the process can be simplified, the cost can be reduced, and the process time can be shortened.

The configuration, function, and operation of the specific fingerprint sensor module 200 will be described below with reference to FIG. 3 to FIG. 7. The configuration, function, and operation of the specific composite sensor 300 8 and Fig. 9 will be described later.

FIG. 3 is a cross-sectional view taken along the line A-A 'in FIG. 2 (b), FIG. 4 is a perspective view of the fingerprint sensor shown in FIG. 3, and FIG. 5 is a schematic configuration diagram of the fingerprint sensor shown in FIG.

As shown, the fingerprint sensor module 200 may include a bracket 210, a fingerprint sensor 220, a bezel 230, and a coating layer 240. The fingerprint sensor 220 includes a flexible connection part 221 formed with an external interface connection line and the connection part 221 may be connected to an upper surface or a lower surface of the base substrate 100 through an adhesive 500 . The details of this will be described later.

The bracket 210 is a member for fixing the fingerprint sensor 220, and determines the overall shape of the fingerprint sensor module 200. When the fingerprint sensor module 200 is used in a flexible substrate or a flexible display, the bracket 210 is preferably made of a flexible material.

The fingerprint sensor 220 is a member having a fingerprint sensing function and is disposed on the upper side of the bracket 210 and includes a sensing unit 223 formed on the flexible substrate 222 and a sensor circuit unit electrically connected to the sensing unit 223 224) (see FIG. 5).

The configuration of the sensing unit 223 and the sensor circuit unit 224 will be described in detail with reference to FIG. The sensing portion 223 is provided on the upper surface of the substrate 222 and the sensor circuit portion 224 is provided on the lower surface of the substrate 222. [ 5B is a bottom view of the substrate 222. FIG. 5C is a sectional view of the sensing unit 223 and the sensor circuit unit 224 are clearly shown in the figure.

The substrate 222 may be a flexible substrate, and may be formed of, for example, a polymide film, but is not limited thereto.

The sensing unit 223 includes a plurality of driving electrodes 223a and an image receiving electrode 223b formed on a substrate 222. [ The driving electrode 223a and the image receiving electrode 223b may be composed of conductor lines.

The driving electrode 223a receives a driving signal from the sensor circuit unit 224 and transmits a signal to the image receiving electrode 223b. The image receiving electrode 223b receives a signal transmitted from the driving electrode 223a via the user (more precisely, the user's finger).

One end of the image receiving electrode 223b positioned on the upper surface of the substrate 222 is formed to extend in the horizontal direction. A plurality of driving electrodes 223a are formed so as to extend in parallel to each other so as to be perpendicular to the extending direction of the image receiving electrode 223b (see Fig. 5 (a)). The image receiving electrode 223b is electrically connected to the sensor circuit portion 224 on the lower surface of the substrate 222. [

One end of the plurality of driving electrodes 223a is spaced apart from the image receiving electrode 223b by a predetermined distance. The other end of the plurality of driving electrodes 223a is electrically connected to the sensor circuit unit 224 on the lower surface of the substrate 222. [

5, the driving electrode 223a and the image receiving electrode 223b are spaced apart from each other, and the driving signal transmitted from the driving electrode 223a is received by the image receiving electrode 223b via the user. At this time, it is possible to recognize the fingerprint by measuring the change of the electric field according to presence or absence of the fingerprint bone or the fingerprint located on the finger of the user.

In the accompanying drawings, only nine driving electrodes 223a are shown, but this is an example, and 200 driving electrodes, for example, may be provided. Divided signal is supplied to the plurality of driving electrodes 223a, the signal is sequentially received from the image receiving electrode 223b, and the fingerprint information of one line can be received. When a user slides a finger with respect to the fingerprint sensor 220, an entire fingerprint image is obtained by stacking the above fingerprint information.

On the other hand, the fingerprint sensor 200 may have more image receiving electrodes than the driving electrodes. In this case, in response to the driving signal applied from the driving electrode, the plurality of image receiving electrodes measure the change of the electric field in accordance with the presence or absence of the fingerprint bone or the fingerprint acid, and the fingerprint can be recognized.

5 (b) and 5 (c), the sensor circuit portion 224 may have an external interface connection line 225 electrically connected to the outside. The external interface connection line 225 is provided on the connection unit 221 and may be, for example, a USB (Universal Serial Bus) or SPI (Serial Peripheral Interface) connection line.

The connecting portion 221 is integrally formed on the flexible substrate 22, and thus has flexibility. The connection part 221 is formed to protrude from the fingerprint sensor module 200 and the connection part 221 is flexible so that the connection part 221 is greatly curved so that the tip part 221a thereof is bonded to the base substrate 100) (see Fig. 3). The adhesive 500 may be made of, for example, an anisotropic conductive film (ACF).

As described above, the fingerprint sensor 220 can be implemented by a COF (Chip-On-Flex) method. In particular, only the sensing unit 223, that is, the driving electrode 223a and the image receiving electrode 223b are formed on the upper surface of the substrate 222, and the sensor circuit unit 224 connected to the sensing unit 223 is formed on the lower surface of the substrate 222 ), It is possible to make the overall contour compact. In addition, it is easier to install the glass on the fingerprint sensor module 200 by not providing the sensor circuit portion on the upper surface of the substrate 222, which is a particularly useful effect in portable electronic devices such as a smart phone. In addition, unlike the conventional technique, the fingerprint sensor 220 is implemented on a flexible substrate, but it does not necessarily require a metal bezel for a driving electrode, thereby contributing to softening of a fingerprint sensor module and further an electronic device. .

The fingerprint sensor 220 basically has a fingerprint detection function. For this purpose, the fingerprint sensor 220 may store information on the characteristic points of the fingerprint (for example, a portion where the fingerprint is divided as in the 'Y' point), and compare the characteristic points to detect whether the fingerprint matches have. In this case, the time taken to detect the fingerprint can be shortened, and the miniaturization can be achieved through simplification of the processor, so that the mountability to the electronic apparatus can be improved.

On the other hand, the fingerprint sensor 220 can have a pointer operation function together with a fingerprint detection function. That is, the fingerprint sensor 220 may include a pointer manipulation function that detects a change over time of the user fingerprint image and moves a pointer such as a cursor based on the movement.

Referring again to FIG. 3, the bezel 230 is positioned on the side surface of the fingerprint sensor 220 and forms the edge of the fingerprint sensor 220. Accordingly, the user can recognize the area where the fingerprint sensor module 200 is located in the portable electronic device through the bezel 230. [ The bezel 230 may be formed to cover all or a part of the edge of the fingerprint sensor 220. The bezel 230 is generally made of resin or rubber, but is not particularly limited thereto.

The bezel 230 may be formed to be integrated with the bracket 210. For example, the bezel 230 and the bracket 210 may be simultaneously formed by injection molding. Here, the bezel 230 may be formed to support the flexible portion of the fingerprint sensor 220. The bezel 230 can serve as a support for fixing the substrate 222 so as to prevent the flexible substrate 222 from swinging due to a step caused by the sensor circuit portion 224. [

The coating layer 240 is located above the bezel 230 and the fingerprint sensor 220. The coating layer 240 may be implemented as a plurality of layers, and various functions may be performed depending on the function of the layer.

For example, the coating layer 240 may include a post-processing layer (not shown) made of a thin film using a paint. The post-processing layer may be formed by, for example, a printing process, a color spray process, a primer process, or an ultraviolet (UV) coating process.

The coating layer 240 may perform various functions such as implementing color on the fingerprint sensor module 200 or reinforcing the upper surface side strength of the fingerprint sensor module 200. Particularly, since the fingerprint sensor 220 includes the sensing portion 223 and the sensor circuit portion 224 located on the upper and lower surfaces of the flexible substrate, the above-described strength enhancement effect is more advantageous. In order to allow the fingerprint sensor 220 to perform proper fingerprint sensing, it is known that the thickness of the coating layer 240 including the post-processing layer is preferably 0.1 mm or less.

A dome switch 250 may be provided on the lower surface of the bracket 210. That is, the dome switch 250 may be positioned between the bracket 210 and the base substrate 100. The dome switch 250 is a mechanical or electrical switching device that detects whether a user is pressed and receives input of desired information or commands. By providing the dome switch 250, a user can switch a pointed menu or icon So that it can be conveniently selected.

As described above, the configuration of the input device 10 according to the embodiment of the present invention has been described, but the present invention is not limited to these embodiments. 6 is a cross-sectional view of an input device for a portable electronic device according to another embodiment of the present invention (a cross-sectional view taken along line AA 'in FIG. 2B), and FIG. 7 is a perspective view of the fingerprint sensor of FIG. Are shown.

Unlike the previous embodiment, in the fingerprint sensor module 200 according to the present embodiment, the dome switch 250 is positioned below the base substrate 100. In addition, in the fingerprint sensor 220, the connection portion 221 protrudes to the side of the fingerprint sensor module 200. The dome switch 250 is disposed on the lower surface of the base substrate 100 instead of connecting the connection portion 221 of the fingerprint sensor 220 to the lower surface of the base substrate 100 as in the previous embodiment, The connection portion 221 of the fingerprint sensor 220 is coupled to the upper surface of the base substrate 100, specifically, between the fingerprint sensor module 200 and the region where the composite sensor 300 is located, using an adhesive.

Next, the composite detection sensor 300 will be described in detail with reference to FIGS. 8 and 9. FIG.

FIG. FIG. 3 is a schematic diagram illustrating a process of detecting a change in magnetic field by a composite detection sensor provided in the apparatus; FIG.

As described above, the compound sensing sensor 300 according to an embodiment of the present invention can sense the approach or contact of a conductor such as a finger of a user or a conductive pen instead of the finger, through a change in capacitance, In addition, the approach or contact of the electromagnetic pen can be detected through the magnetic field. That is, the hybrid sensing sensor 300 is capable of sensing both of a capacitive sensing method and an electromagnetic induction sensing method. Accordingly, while the user uses the touch screen of the display unit using the electromagnetic pen, the user can continuously operate the separate function key using the electromagnetic pen.

FIG. 8 shows a capacitance sensing process. The complex sensing sensor 300 includes a transmitting electrode 310 and a receiving electrode 320 provided on a substrate. The transmitting electrode 310 receives a driving signal from a separate circuit unit and sends the driving signal to the outside, and the receiving electrode 320 receives the driving signal transmitted through a conductor (user). The electric field E formed from the transmitting electrode 310 to the receiving electrode 320 is different from the case where the user does not approach or contact the user when the user U approaches or contacts the compound sensing sensor 300 to a sufficient degree , Which is recognized as a change in capacitance. Thus, it is possible to detect whether or not the user U has made a touch.

FIG. 9 shows an electromagnetic induction sensing process using an electromagnetic pen. Here, the electromagnetic pen is a pen using an electromagnetic wave, and collectively refers to an EMR pen, a magnetic pen, and the like.

The hybrid sensing sensor 300 includes a loop coil 330 and a magnetic sensor 340 provided on a substrate for sensing electromagnetic waves. When a current is passed through the loop coil 330, a magnetic field M is generated, and the magnetic field M is absorbed by the electromagnetic pen 600.

The electromagnetic pen 600 includes a capacitor 610 and a coil 620, and can discharge the absorbed magnetic field M at a predetermined frequency. The magnetic field M emitted by the electromagnetic pen 600 can be absorbed again by the loop coil 330 of the composite sensing sensor 300 so that the magnetic sensor 340 can detect that the electromagnetic pen 600 is sufficiently strong It is possible to detect whether it has been accessed or contacted. When a plurality of loop coils 330 are installed, it is possible to sense not only the approach / contact of the electromagnetic pen 600, but also the position where the electromagnetic pen 600 approaches / contacts.

After the fingerprint sensor module 200 and the composite sensor 300 are installed on the base substrate 100, a process of attaching a glass on the base substrate 100 or mounting the same on an electronic device may be followed . The description thereof will be omitted because it is beyond the scope of the present invention.

In particular, a fingerprint sensor can be used to provide a convenient home key having a security function. Further, by using a composite sensing sensor capable of both the capacitive type and the electromagnetic pen type input, it is possible to provide a function key that gives a good user experience.
