In recent years, a sensing light is emitted and an optical signal is changed according to the movement of a finger, A pointing device for receiving desired information or commands has been developed and applied to many portable electronic devices.

On the other hand, most of the currently available laptops are equipped with a touch pad 18 at the lower end of the keyboard to provide the user with the same mouse environment as the desktop PC (see FIG. 1).

The touch pads on the recently released notebooks provide not only the pointing function, but also the functions that allow the user to control the screen in various ways through multi touch. For example, you can use two fingers to enlarge or reduce the screen displayed on the monitor as you do on a tablet PC, or you can scroll the page up and down.

In the case of a touch pad that provides a conventional multi-touch function, it is advantageous in that the user can easily and intuitively perform various screen controls using his / her finger.

However, due to the size of the touch pad, not only a mounting space of a certain area or more is required on the notebook, but also a restriction is imposed on the mounting position in consideration of the shape of the terminal and the usage behavior of the user.

In addition, due to the size of the touch pad, most of them are located at the bottom of the keyboard. Therefore, in order to use the touch pad while performing the keyboard-oriented operation, it is inconvenient to repeatedly lower the hand to the bottom of the keyboard.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems,

And a user can more conveniently control a user interface on the screen by using a plurality of pointing devices.

Furthermore, by disposing a plurality of pointing devices at the central portion of the keyboard, it is intended to solve the inconvenience that the user repeatedly moves his / her hand to the lower portion of the keyboard to use the touch pad while using the keyboard.

In addition, an object of the present invention is to enable a user to easily lock a desired file by using a pointing device supporting a navigation function of a pointer or a cursor and a pointing device supporting a fingerprint authentication function on a display screen.

According to an embodiment of the present invention, a method of controlling a screen by using a plurality of pointing devices includes: a program or file corresponding to a program or a file from a first pointing device in a state in which a controller is positioned in an area of an item displaying a program or a file; Determining whether a dome click signal is detected for selecting a signal; Determining whether a fingerprint input signal is detected from a second pointing device while a dome click of the first pointing device is maintained; And when a fingerprint input signal is detected from the second pointing device, locking the selected program or file according to the fingerprint input signal.

FIG. 2 is an exemplary diagram for explaining a terminal according to an embodiment of the present invention, and FIG. 3 is a block diagram illustrating a configuration of a terminal according to an embodiment of the present invention. A terminal according to the present invention can be a notebook, a tablet PC, a smart phone, an E-book, and the like.

2 and 3, the mobile terminal 100 according to the present invention includes a first pointing device 101 that supports navigating a pointer or a cursor on a screen, and a second that supports a user fingerprint authentication function. A pointing device 103, a communication unit 105, a display unit 107, a memory 109, and a control unit 111 are provided.

The first pointing device 101 generates and moves a cursor or a pointer on the screen of the portable terminal through the movement of the finger so that the same pointing technology as that of the PC (Personal Computer) is implemented. In addition, the first pointing device 101 allows the scroll function to move the displayed content on the screen up or down or to the left or right.

For example, when the user moves his / her finger after raising his / her finger on the first pointing device 101, the cursor (or pointer) on the screen moves according to the moving direction. At this time, the first pointing device 101 may sense the physical contact of the finger or may sense the light reflected by the finger, and may generate the motion detection signal accordingly.

Here, the 'finger' may be understood as another part of the body, and the first pointing device 101 may be another replaceable object capable of grasping the movement even if it is not a body.

In this case, the first pointing device 101 may be implemented as an optical track pad (OTP), but may also include an optical joystick, a hall sensor, a fingerprint recognition sensor, a pressure sensor, And may include a dome click switch S / W that can detect a finger pressing operation of a user.

Here, the optical track pad (OTP) is an optical mouse for a portable terminal, and is an optical pointing device that implements an optical mouse function used in a personal computer in a mobile device. The technology for such an optical touch pad (OTP) is a disclosed technology, and a detailed description thereof will be omitted.

The second pointing device 103 is a separate input device physically separated from the first pointing device 101 and is an input device of the same configuration that performs the same function as the first pointing device 101 described above.

In addition, the second pointing device 103 performs a user fingerprint authentication function.

More specifically, the second pointing device 103 is

2, the first pointing device 101 is located on the left side of the keyboard of the terminal 100 and the second pointing device 103 is located on the right side. However, the present invention is not limited thereto.

The communication unit 105 forms a communication channel between the portable terminal 100 and the base station, and takes charge of a series of communications for transmitting and receiving necessary signals. The communication unit 105 may include an RF transmitter for up-converting and amplifying the frequency of the transmitted signal, an RF receiver for low-noise amplifying the received signal and down-converting the frequency. In particular, when the communication unit 105 accesses a web site via the wireless Internet, the communication unit 105 takes charge of communication between the portable terminal 100 and the base station.

The display unit 107 may include a display device such as an LCD, an OLED, and an LED.

The display unit 107 is under the control of the control unit 111 to display a series of operation states, operation results, and a plurality of pieces of information in the portable terminal 100.

The memory 109 stores data and programs necessary for implementing the present invention.

The control unit 111 detects whether the first input signal from the first pointing device 101 and the second input signal from the second pointing device 103 are input to control the screen displayed on the display unit 107. [

When an input signal is detected from the first pointing device 101 and the second pointing device 103, the control unit 111 executes a predefined screen control function using the sensed input signal. At this time, the input signal may be a displacement signal corresponding to the finger movement or a dome click signal generated by the pressing of the dome click switch.

More specifically, when the first input signal and the second input signal are simultaneously detected from the first pointing device 101 and the second pointing device 103 (in this case, The input signal is a displacement signal), the control unit 111 computes the first input signal as a first displacement for one of two or more different axial directions, and the second input signal as one of two or more different axial directions Direction as the second displacement. Then, the control unit 111 executes a predefined screen control function based on the combination of the first displacement and the second displacement described above.

For example, the control unit 111 may control the operation of switching the screen, moving the home page, scrolling the page, zooming in, zooming out, moving the previous program, moving the next program, clockwise rotation of the object, Directional rotation of the screen.

If the second input signal is sensed from the second pointing device 103 while the first input signal is sensed from the first pointing device 101, the control unit 111 controls the first And executes the predefined screen control function based on the combination of the displacement and the second displacement. For example, the controller 111 performs functions such as text selection, multiple icon selection, window movement, file, and the like.

In addition, the controller 111 may detect the first input signal (for example, a signal generated when the user clicks on a specific program or file displayed on the screen) from the first pointing device 101. When a fingerprint input signal (for example, a signal generated from the second pointing device by swiping a finger from the top to the bottom) is detected, the control unit 111 combines the first input signal and the second input signal. Based on this, the predefined screen control function is executed. For example, the controller 111 performs a function of locking a file or a program selected by a user (for example, a click).

Each screen control function will be described in more detail with reference to the following description.

On the other hand, it is preferable that the above-described screen control function in the control section 111 is executed only when the absolute values of the first side and the second displacement for a predetermined time exceed the set critical displacements respectively. When the first displacement and the second displacement do not exceed the corresponding critical displacements, by preventing the predefined screen control function from being performed, it is possible to minimize the occurrence of erroneous operation due to the user's fine finger movement. That is, when a value below the critical displacement is detected, it is ignored, thereby preventing the screen control from being executed regardless of the intention of the user.

FIG. 4 is a flowchart for explaining a method of controlling a screen using a plurality of pointing devices according to the present invention. When a first input signal and a second input signal are detected from a first pointing device and a second pointing device, Fig.

Referring to FIG. 4, the controller determines whether the first input signal and the second input signal are simultaneously detected from the first pointing device and the second pointing device (S110).

If it is determined in step S110 that the first input signal and the second input signal are detected at the same time, the controller calculates the first input signal as a first displacement in one of two or more different axial directions (S120). Then, the control unit computes the second input signal as a second displacement in one of two or more different axial directions (S130).

Steps S120 and S130 may be performed simultaneously.

In step S120, the control unit receives the first input signal (DELTA x, DELTAy) from the first pointing device for a predetermined period of time, calculates a sum (absolute value) of DELTA x ) Is selected to determine whether the finger movement in the first pointing device is the X-axis direction or the Y-axis direction. When the axial direction is determined, it is determined whether the selected value is the positive or negative direction of the axial direction, and the first displacement is calculated.

In step S130, the second displacement is calculated in the same manner as in step S120.

If the first displacement and the second displacement are calculated through steps S120 and S130, the controller determines whether the calculated first displacement and the second displacement exceed the critical displacement, respectively, at step S140. When a value lower than the critical displacement is detected, it is possible to prevent the screen control from being executed regardless of the intention of the user by ignoring the value.

If it is determined in step S140 that the first displacement and the second displacement exceed the threshold displacement, the controller performs a predefined screen control function using the first displacement and the second displacement (S150).

Hereinafter, an exemplary screen control function that can be performed in step S150 will be described with reference to FIGS. 5 to 11. FIG.

5, it is assumed that two or more program windows (for example, an Internet browser window and an office program window) are executed on the screen, and the first pointing device 101 and the second pointing device 103 simultaneously output Z (For example, when a dome click signal is simultaneously detected from the first pointing device and the second pointing device) from the first pointing device 101, Axis is detected from the second pointing device 103 at the same time, the control unit divides the screen at the same ratio to display two windows currently being executed on the screen (Fig. 5 Reference). That is, when the user swipes both fingers outward in a state where the user has clicked the first pointing device 101 and the second pointing device 103 with the finger, Is displayed.

6, when a displacement in the opposite directions with respect to the X-axis direction is simultaneously detected from the first pointing device 101 and the second pointing device 103, the control unit displays the activated or selected object (image, Web page, image, program page, etc.) according to the corresponding displacement.

For example, when a displacement in the X-axis positive direction is sensed from the first pointing device 101 and a displacement in the X-axis negative direction is sensed from the second pointing device 103, the selected object is contracted, When a displacement with respect to the X-axis sound direction is sensed from the first pointing device 101 and a displacement with respect to the X-axis positive direction is sensed from the second pointing device 103, the selected object is enlarged (Figs. 9).

When the displacements of the first pointing device 101 and the second pointing device 103 in the opposite directions with respect to the Y-axis direction are simultaneously detected, the control unit displays the activated or selected objects (image, web page, Etc.) to rotate clockwise or counterclockwise according to the displacement.

For example, when a displacement in the Y-axis positive direction is detected from the first pointing device 101 and a displacement in the Y-axis negative direction is detected from the second pointing device 103, When a clockwise rotation is performed and a displacement in the Y-axis negative direction is sensed from the first pointing device 101 and a displacement in the Y-axis positive direction is detected from the second pointing device 103, The object is rotated counterclockwise.

10, the control unit 111 detects the displacement of the X-axis sound direction from the first pointing device 101 and the second pointing device 103 at the same time or simultaneously detects the displacement of the X- If a displacement is detected, the movement to the previous or next application is performed.

For example, assuming that 'A', 'B', and 'C' applications are currently running and that the 'A' application program is active, the first pointing device 101 and the second pointing device 103 is simultaneously detected from the first pointing device 101 and the second pointing device 103, a movement to the previous application program ('C') is performed, If a displacement in the positive direction is sensed, the movement to the next application ('B') is performed.

Next, referring to FIG. 11, FIG. 11 is a diagram illustrating an example in which the present invention is applied to 'Windows 8', an operating system of Microsoft Corporation. The operating system 'Windows 8' consists largely of [Start Screen], [All Apps Screen], and [Desktop Screen].

Under the Window 8 operating system environment, the control unit 111 detects the displacement of the Y-axis sound direction simultaneously from the first pointing device 101 and the second pointing device 103, , Screen switching is performed sequentially.

For example, the first pointing device 101 and the second pointing device 103 can communicate with each other on the assumption that there is a [Start screen - All Apps screen - Desktop screen] The control unit 111 switches the screen from the [Start screen] to the [Desktop screen], and when the displacement from the first pointing device 101 and the second pointing device 103 is detected At the same time, when the displacement of the Y-axis sound direction is detected, the control unit 111 switches the screen from [Start Screen] to [All Apps Screen].

Meanwhile, the above-described steps S120 and S130 are not limited to the above-described method.

As another example, a value obtained by calculating the first input signals? X1 and? Y1 and the second input signals? X2 and? Y2 as vectors may be used, and the first input signals? X1 and? Y1 and the second input signals DELTA x2, DELTA y2) may be used as a specific coordinate value.

Hereinafter, a screen control method according to another embodiment of the present invention will be described with reference to FIGS. 12 to 14. FIG. The first pointing device 101 and the second pointing device 103 support the left button click and the right button click in the same manner as the PC mouse environment. To this end, the first pointing device 101 And the second pointing device 103 are each provided with a dome click switch S / W for detecting the finger pressing operation of the user.

12, in a screen where a selectable text such as a word program or a text displayed on a web page is displayed, the control unit 111 determines whether or not a displacement in the Z-axis direction is sensed from the first pointing device 101 (I.e., the first pointing device 101 maintains a dome click), when a second input signal is detected from the second pointing device 103 The control unit 111 determines whether the first pointing device 101 has been clicked or not based on the second input signal from the second pointing device 103 based on the point on the screen where the first pointing device 101 is clicked, As in 12, let the text area be selected. That is, the control unit 111 designates the start point of the text area according to the dome click signal from the first pointing device 101, and enlarges or reduces the area according to the displacement signal from the second pointing device 103 . This is the same concept as selecting the text by moving the mouse with the left mouse button of the PC clicked.

Next, referring to FIG. 13, in a desktop screen in which a plurality of selectable icons are displayed, the control unit 111 determines whether the first pointing device 101 holds a dome click, When the second input signal is detected from the device 103 (in this case, the second input signal is a displacement signal generated by the swipe motion of the finger), the control unit 111 determines whether the first pointing device 101 is clicked The plurality of icons are selected in accordance with the second input signal from the second pointing device 103 on the basis of the point on the screen. That is, the control unit 111 designates the start point of the area for icon selection according to the dome click signal from the first pointing device 101, and enlarges the area according to the displacement signal from the second pointing device 103 Or reduced. This is the same concept as selecting multiple icons by moving the mouse with the left mouse button of the PC clicked.

Referring to FIG. 14, in a screen in which one or more program windows are displayed, the controller 111 receives a dome click (click) from the first pointing device 101 in a state where a pointer is positioned in a predetermined area of a top portion of a program window displayed on the screen ) Signal is detected, it is determined whether or not the second input signal is sensed from the second pointing device 103 while the first pointing device maintains the dome click. When the second input signal is detected from the second pointing device, the control unit 111 changes the position of the program window displayed on the screen in accordance with the second input signal from the second pointing device 103. [ This is the same concept as moving the position of the program window by moving the mouse while positioning the pointer at the top of the program window and then clicking the button outside the PC.

15 to 18 are diagrams for explaining a method of controlling the UI displayed on the screen by using the first pointing device 101 and the second pointing device 103 individually.

15, the controller 111 changes the position of the pointer displayed on the screen according to the first input signal input from the first pointing device 101, on the desktop screen in which a plurality of selectable icons are displayed Or select an icon located on a specific icon. That is, when the first input signal is a displacement signal, the controller 111 moves the pointer on the screen according to the displacement signal. If the first input signal is a dome click signal, the controller 111 selects or selects an icon at a point where the pointer is located. . The control unit 111 determines whether a dome click signal is detected from the second pointing device 103 while a specific icon on the screen is selected. If the dome click signal is detected, an option to control the corresponding icon Window (the same as when you right-click a specific icon in the PC environment) is displayed on the screen. At this time, in a state where the option window is displayed on the screen, the user can selectively activate the control items displayed on the option window by swiping the second pointing device 103 in the vertical direction.

Referring to FIG. 16, in a screen where a web page is displayed, the control unit 111 changes the position of the pointer displayed on the screen according to the first input signal input from the first pointing device 101, Execute the item selectively. The control unit 111 determines whether the displacement signal is sensed from the second pointing device 103. When the displacement signal is sensed, the control unit 111 allows the contents displayed on the web page to be moved up or down or left or right according to the displacement signal Allow page scroll functionality to be implemented (same as when operating the mouse wheel in a PC environment). Here, the page scrolling means an operation of moving the page or data displayed on the display unit up and down.

16, the present invention is not limited to the web page screen. The present invention can be applied to other application programs (e.g., office programs, image editing programs, etc.) having windows or frames that can be vertically or horizontally scrolled This is self-evident.

17, on the screen where the media playback program is being executed, the control unit 111 determines whether a displacement signal is sensed from the second pointing device 103, and when the displacement signal is sensed, Increases or decreases the volume according to the signal.

 17, on the screen where the media playback program is being executed, the control unit 111 determines whether a displacement signal is sensed from the second pointing device 103, and when the displacement signal is sensed, Increases or decreases the volume according to the signal.

Next, referring to FIG. 18, FIG. 18 is an example of a [Start screen] of the operating system 'Windows 8' of Microsoft Corporation. [Start screen] of 'Windows 8' consists of menu items of tile type of different colors. In general, in PC mouse environment, place the pointer on each menu item and click the right button of mouse , An option window (Unpin from Start, Unistall, Smaller, etc.) is displayed at the bottom of the screen to control the corresponding menu item.

Under the Windows 8 operating system environment, the controller 111 changes the position of the pointer displayed on the screen according to the first input signal input from the first pointing device 101. At this time, the controller 111 automatically switches to the 'activation mode' when the pointer enters the image area representing the tile-shaped menu item (that is, when the pointer is located inside the image area) The position of the pointer displayed on the screen is changed according to the first input signal only when the pointer is located outside the image area indicating the menu item of the form. Here, 'activation mode' means that the corresponding menu item is selected (that is, activated), and generally selected menu items are differentiated from other menu items. If a dome click signal is detected from the second pointing device 103 while a specific menu item is active, the control unit 111 displays an option window (Unpin from Start, Uninstall, Smaller, etc.) ) Is displayed at the lower end of the screen.

FIG. 19 is an exemplary diagram for describing a method of setting a lock on a specific program or file displayed on a screen by using the first pointing device 101 and the second pointing device 103. In this case, 'lock' means to prevent the use of the file or program by a user other than the user who set the lock.

Referring to FIG. 19, in a screen displaying one or more programs or files selectable by a user, the controller 111 may display the first pointing device 101 while the pointer is positioned in an area within an item displaying a program or file. When the dome click signal is detected, the first pointing device 101 determines whether the fingerprint input signal is detected from the second pointing device 103 while the dome click is maintained.

In this case, the 'fingerprint input signal' may be generated by the user swiping a finger from the top to the bottom on the second pointing device 103.

When the fingerprint input signal is detected from the second pointing device 103, the controller 111 locks a program or file displayed on the screen according to the fingerprint input signal from the second pointing device 103. do.

For reference, unlocking (ie, entering or executing) a locked file or program may be achieved by a method as illustrated in FIG. 20.

Referring to FIG. 20, when a user selects (ie, clicks) a file or program that is locked using the first pointing device 101 and inputs a fingerprint using the second pointing device, You can run a program or file.

21 illustrates an embodiment of a second pointing device 103 in accordance with the present invention. 21 and 22 are a perspective view and a cross-sectional view showing an embodiment of a pointing device according to the present invention.

The pointing device 103 according to an embodiment of the present invention includes a signal output terminal 110, a housing 120, and a sensor 130.

The signal output terminal 110 emits, i.e., outputs, a sensing signal for pointing. The housing 120 accommodates the sensor 130 and the sensor 130 has pixels arranged for pointing in an array form. It has a sensing area.

In this embodiment, the sensor 130 is mounted on a substrate (PCB, 140), for example, a printed circuit board (PCB), the signal output terminal 110 is the outer (outer side of the sensor 130). ) Is electrically connected to the housing 120. The housing 120 surrounds and protects the sensor 130, and an outer circumferential surface of the housing 120 is stepped. In the present exemplary embodiment, the signal output terminal 110 refers to a portion of the substrate 140 where the sensing signal is output (emitted).

More specifically, the signal output terminal 110 emits a sensing signal for pointing, and the sensing signal is radiated to a subject such as a finger through the housing 120. The sensing signal is not limited to the RF signal because various types of sources such as light or radio waves, for example, a radio frequency (RF) signal, may be used as the sensing signal.

In addition, when an electrical signal including an RF signal is output from the signal output terminal 110 in the state in which the fingerprint of the finger is in contact with the pointing device 100, A difference in electrical characteristics occurs, for example, a difference in capacitance due to a height difference between a peak and a valley of a fingerprint occurs, and accordingly, the sensor 130 detects a fingerprint image and a finger movement.

Specifically, the sensor 130 or the budda fingerprint sensor generates an image or a template through the above-described electrical characteristic difference, and the generated fingerprint image or template may not only identify a fingerprint, authenticate a user, but also move a finger (movement distance / It also tracks the direction of movement. In the present invention, a configuration for performing all movements of a subject (finger) for identification, authentication, and navigation (pointing) of a fingerprint is called a sensor, particularly a fingerprint sensor.

Thereafter, the fingerprint image sensed by the sensor 130 is converted into an electrical signal and then transferred to a microcomputer (not shown) of an electronic device such as a mobile phone through the substrate 140.

In the present embodiment, the housing 120 functions as an antenna for transmitting the sensing signal output from the signal output terminal 110 to the outside, that is, the subject (finger) side, for this purpose, the housing 120 is It is electrically connected to the signal output terminal 110. Accordingly, the sensing signal generated by the signal output terminal 110 propagates to the subject, that is, the finger, through the housing 120 as a medium.

The housing 120 is provided with a conductive part for transmitting the sensing signal to the outside, such as a conductive material such as a metallic conductor or a conductive coating as in another embodiment described later is applied to the housing 120 Can be.

The housing 120 is coupled to the substrate 140 in a manner such as surface mount (SMT), but is not limited thereto, and fixes the sensor 130 interposed therebetween. In addition, the housing 120 has a case shape surrounding the periphery of the sensor 130 and has an outer circumferential surface forming a step to facilitate mounting of the pointing device to an electronic device such as a mobile terminal. When the pointing device 100 is mounted on the electronic device, the inside of the electronic device may not be identified from the outside of the electronic device by the lower flange of the housing 120, thereby providing a concise appearance.

In the present embodiment, the housing 120 has a conductive signal transmitting portion.

In more detail, the housing 120 uses the conductive member 121 as a signal transmitting unit for transmitting the sensing signal, for example, the RF signal, and the housing member 122 as a synthetic resin material (synthetic resin). An antenna frame is disclosed as an example of the conductive part.

The antenna frame 121 is provided inside the housing member 122 as a metal material, and the housing member 122 is a main frame forming an edge of the housing and forms the flange of the housing described above. The housing member 122 is a part in contact with the electronic device, and may be produced in a form suitable for assembly to a portable terminal by injecting a synthetic resin such as plastic.

In addition, the housing 120 is electrically connected to the signal output terminal 110 and configured to output a sensing signal (RF signal) to the upper side of the sensor, that is, the region where the subject is located. In the present embodiment, the antenna frame 121, that is, the conductive part is combined with the housing member 122 to form the housing 120, and one side of the antenna frame 121 is electrically connected to the signal output terminal 110. Connected to receive the sensing signal and the upper end of the antenna frame 121 is exposed to the upper surface of the pointing device to emit the sensing signal to the outside. Here, the antenna frame 121 and the signal output terminal 110 on the substrate 140 may be bonded by a conductive adhesive, for example, a conductive material such as silver epoxy, and the antenna frame 121. By exposing to the top surface of the pointing device, a glossy, brilliant, or glossy image can be implemented.

Thus, when the bottom surface of the finger, that is, the finger surface on which the fingerprint is formed, is located above the sensor 130, the sensing signal is transmitted to the bottom of the finger through the housing 120, in particular the antenna frame 121. Propagated to cotton. When the sensing signal propagates to the subject (finger) through the housing 120, the sensing signal causes a difference in capacitance due to a difference in electrical characteristics of a valley and a ridge of a fingerprint of a finger. do. The signal sensed by the sensor 110 may be converted into an electrical signal, amplified by an amplifier (not shown), and transmitted to a microcomputer of the portable terminal through a connector such as a flexible printed circuit board (FPCB) 150.

Here, the antenna frame 121 may be fixed to the housing member 122 by insert injection, but is not limited thereto. When the insert is injected, the antenna frame 121 is first manufactured according to the standard of the sensor 130, and the housing member 122 meets the standard of the portable terminal, more specifically, the mounting part of the pointing device. Inserts are injected in shape and size.

On the other hand, the pointing device 100 according to an embodiment of the present invention may further comprise a dome switch 160. The dome switch 160 may be used to generate a signal for selecting a pointed menu or icon.

The pointing device 100 according to the present invention may further include a UV resin layer 170 coated on an upper surface of the sensor 130, that is, the surface of the sensor facing the object. It is possible to prevent or minimize the generation of scratches due to external stimuli on the surface of the 130). The UV resin layer 170 may be coated only on the upper side of the sensor 120, but may be further coated on the upper side of the housing 120 as well as the upper side of the sensor 130. The UV resin layer 160 may have a thickness of 70 μm or less.

As described above, in one embodiment of the present invention, since the housing 120 includes an antenna frame that is a signal transmitting unit 121 and a housing member that is a synthetic resin unit 122, the housing 120 is included in a standard or design of an electronic device. Not only can it be suitably mounted, but also outputs the RF signal output from the signal output terminal 110 (RF terminal) to the bottom surface of the finger, so that the sensing signal for fingerprint recognition and movement detection can be efficiently applied to the sensor 130. Allow input.

Meanwhile, the housing 120 may have a color in accordance with design requirements. For example, the surface of the housing, in particular, the surface of the antenna frame 121 is formed with a color layer painted in accordance with the design requirements can be improved aesthetics. The color layer may be protected by coating the UV resin layer 170 on the color layer.
