Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object present in the vicinity without using a mechanical contact by using an electromagnetic force or infrared rays. The proximity sensor 141 may be disposed at an inner region of the mobile terminal covered by the touch screen described above or near the touch screen.

Examples of the proximity sensor 141 include a transmission photoelectric sensor, a direct reflection photoelectric sensor, a mirror reflection photoelectric sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of the object by the change of the electric field according to the proximity of the conductive object. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, an action of allowing the object to be recognized without being in contact with the touch screen so that the object is located on the touch screen is referred to as a "proximity touch", and the touch The act of actually touching an object on a screen is called a "contact touch." The position at which the object is in close proximity touch on the touch screen means a position where the object is perpendicular to the touch screen when the object is in close proximity touch.

Here, the touch object is an object applying a touch to the touch sensor and may be, for example, a finger, a touch pen or a stylus pen, a pointer, or the like.

As such, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and then transmits the corresponding data to the controller 180. As a result, the controller 180 can know which area of the display unit 151 is touched. Here, the touch controller may be a separate component from the controller 180 or may be the controller 180 itself.

Meanwhile, the controller 180 may perform different control or perform the same control according to the type of touch object that touches the touch screen (or a touch key provided in addition to the touch screen). Whether to perform different control or the same control according to the type of touch object may be determined according to the operation state of the mobile terminal 100 or an application program being executed.

On the other hand, the controller 180 can calculate the position of the wave generation source through the information detected from the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the property that the light is much faster than the ultrasonic wave, that is, the time that the light reaches the optical sensor is much faster than the time when the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generation source may be calculated using a time difference from the time when the ultrasonic wave reaches the light as the reference signal.

On the other hand, the camera 121, which has been described as the configuration of the input unit 120, includes at least one of a camera sensor (eg, CCD, CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The photo sensor may be stacked on the display element, which is configured to scan the movement of the sensing object in proximity to the touch screen. More specifically, the photo sensor mounts a photo diode and a transistor (TR) in a row / column to scan contents loaded on the photo sensor by using an electrical signal that changes according to the amount of light applied to the photo diode. That is, the photo sensor calculates coordinates of the sensing object according to the amount of light change, and thus, the position information of the sensing object can be obtained.

It is apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit and essential features of the present invention.

As multimedia functions become more important, the wireless communication technology performed by the mobile terminal 100 may be performed in various forms such as short distance, long distance, or between devices. Since different frequency bands (resonant frequencies) are used, different antennas must be used. do.

In order to support the transmission and reception of large amounts of data, LTE (4th generation mobile communication), the 4th generation mobile communication technology, has emerged. There is a need for an ultra-wideband mobile communication technology capable of transmitting and receiving. Fifth generation mobile communication technology is being developed. Wireless technology for 5G mobile communication is called NR (New Radio) in 3GPP (3rd Generation Partnership Project), and International Telecommunications Union (ITU) is called International Mobile Telecommunication (IMT-20-2020). It is a communication method implemented by the method.

In addition to transmitting fast and large amounts of data through 5G mobile communication, the reliability of data transmission may be improved and a function of supporting IoT may be added according to the spread of the Internet of Things (IOT).

5G is a mobile communication technology with a maximum download speed of 20Gbps and a minimum download speed of 100Mbps. In addition, the Internet of Things (IoT) service can be provided to a million devices within a 1㎢ radius, and free communication is possible even at a high speed train of 500 km per hour. The download speed is 280 times faster than LTE. It is a wireless communication technology that can download a 1GB movie in 10 seconds.

5G mobile communication has noticeably improved response speed as well as transmission speed. If the data transfer rate is an indicator of how much data can pass through at one time, the response rate determines how long it takes for small data to travel.

At 4G, the response speed is up to 10-50ms (milliseconds, milliseconds). At 5G, this response is about 10 times faster. Thanks to this, 5G will be actively introduced in the fields of autonomous vehicles and the Internet of Things (IoT), where a large amount of data must be seamlessly exchanged with a central server.

Frequency bands of the centimeter wave (sub-6: 3 GHz to 30 GHz) and the millimeter wave (mmWave: 30 GHz to 300 GHz) may be used, and a communication method using a signal of a frequency band below 6 GHz is particularly called Sub-6.

Sub-6 includes N41 using the signal band of 2.5GHz to 2.7GHz and N78 using the signal band of 3.3GHz and 3.8GHz and below, and the frequency band used may vary from country to country. For products with specifications available around the world, antennas are needed that achieve performance in both frequency bands.

The existing LTE antenna has been improved several times, and the structure of the antenna is complicated. For broadband LTE, an antenna structure capable of extending a bandwidth at a resonant frequency is required, and a signal of another frequency band may be received for LTE-Advenced (LTE-A) using signals of several frequency bands instead of one frequency band. There is a need for a plurality of antennas or antennas capable of multi-resonance.

A plurality of antennas are used to cover all signals such as a frequency band below 1 GHz (low band) and a signal around 2 GHz (mid band) and a frequency band above 2.2 GHz (high band). It is necessary to provide.

In addition, a plurality of antennas are required to apply a multiple input multiple output (MIMO) technique. Multi-input / output method has two or more antennas in the base station and the mobile terminal to transmit data through several paths, and detects it at the receiving end to reduce interference and lower each transmission rate. Can transmit

Since the antenna for transmission is more sensitive to interference than the antenna for reception, it is generally located in a position that minimizes interference with other electronic components. It is electrically connected to a wireless communication unit for LTE communication can transmit or receive a signal corresponding to the resonance frequency of each antenna.

As described above, only four antennas for improved LTE mobile communication may be applied, and additionally, antennas for wireless communication such as WIFI, Bluetooth, and GPS may be additionally provided.

Even if the mobile communication method using 5G mobile communication is put into practical use, 5G communication is limited due to the lack of facilities for 5G communication and existing terminals cannot perform 5G communication. The terminal also needs a mobile terminal 100 that can use both methods.

Since the 5G antenna uses a beamforming method to control the radiation direction, the radiation direction is limited. Therefore, a plurality of 5G antennas are required to secure the radiation range in all directions and to prevent the radiation performance from deteriorating when the user grabs the mobile terminal 100 by hand. The mobile terminal 100 of the present invention may include an antenna 250 radiating toward the rear surface and an antenna 200 radiating toward the side surface.

The LTE antenna may be positioned above or below the mobile terminal 100 to minimize mutual interference with a conductive object such as a display unit 151, a printed circuit board (not shown), and a middle frame 105. Recently, an antenna may be implemented by using a metal side case 104. The side case 104 of the mobile terminal 100 is not only used as an antenna, but also a space in which an opening for outputting sound of the sound output unit and a second operation unit 123b positioned at the side thereof are disposed is shown in FIGS. 1B and 1C. As is, the lower part of the 2nd operation part 123b remains.

As illustrated in FIGS. 1B and 1C, the antenna module 210 for 5G mobile communication may be disposed at positions not overlapping with the second operation unit 123b among the left and right sides of the mobile terminal 100. When the antenna radiator is disposed inside the side case 104, transmission and reception of signals are impossible by the metal side case 104. Therefore, the side case 104 corresponding to the portion where the antenna module is located needs to be replaced with a non-metallic material.

2 is a view for explaining the configuration of the antenna module 210 and the side case of the mobile terminal 100 of the present invention, Figure 3 is an exploded perspective view of the antenna module 210 of FIG. The antenna module 210 is disposed toward the side of the mobile terminal 100 and the position at which the antenna module 210 is radiated should be a non-metal material. The side case 104 includes a metal part 104a and a non-metal part 104b. ).

The side case 104 may be partitioned using the non-metal part 104b in an appropriate length according to the length of a signal to be transmitted and received so that the metal part 104a may be used as a plurality of antennas. In other words, the non-metal part 104b may be disposed between the metal parts 104a. In addition, as described above, the non-metal part 104b should also be disposed at a position corresponding to the radial direction of the antenna module 210 located inside the mobile terminal 100.

The case of the mobile terminal 100 may provide a unified appearance consisting of one body such as a unibody. Prefer Therefore, in consideration of design aspects, it is desirable to minimize the number of possible non-metal parts 104b. However, the side case 104 of the present invention must be additionally provided with a non-metal part 104b for the radiation performance of the antenna module 210 mounted therein, the non-metal located in the radial direction of the antenna module 210. The unit 104b is used as the light output unit.

Referring to FIG. 2, the antenna module 210 is disposed adjacent to the side case 104, and the non-metal part 104b is positioned corresponding to the mounting portion of the antenna module 210.

The non-metal part 104b of the side case 104 may be combined with the metal part 104a in a double injection method, or may be separately injection molded and bonded to form one side case 104. The non-metal part 104b has a light guide part 221 for guiding the light incident from the light source 225 mounted inside the case to exit the mobile terminal 100. As shown in FIG. 2, a hole is formed in the non-metal part 104b for the light guiding part 221 so that the light exit part 221a through which the light of the light guiding part 221 is emitted may be exposed to the outside. The light guide portion 221 may be inserted by forming a groove inside the 104b.

The former has the advantage that the brightness of the emitted light is good and the latter has the advantage of waterproof performance and the interface between the two members is not visible from the outside. The tape 224 may be further included to fasten the light guide portion 221 to the side case 104.

The antenna module 210 includes an antenna radiator for emitting a signal, and in this embodiment, a patch antenna radiator may be used to transmit and receive a millimeter wave (mmWave). An antenna module 210 packaged as a single wireless communication unit that is responsible for transmitting and receiving wireless signals may be used. Alternatively, the antenna module 210 may be controlled to mount a wireless communication unit on the main board and to transmit and receive a signal from the antenna radiator by using a signal line such as a flexible board or a coaxial cable.

The antenna module 210 may be disposed such that the antenna radiator of the antenna module 210 radiates toward the side case 104, and the non-metal part 104b is formed larger than the radiation area to transmit and receive signals from the antenna module 210. Can be minimized by the metal part 104a of the side case 104. The antenna module 210 may further include an antenna bracket 230 for fixing the antenna module 210 to the case of the mobile terminal 100. A tape 231 may be coupled to one side of the antenna bracket 230, and an opening may be formed in the antenna bracket 230 as shown in FIG. 3 so that signals transmitted and received by the antenna radiator are not disturbed.

The light source 225 may include an LED and may be disposed at both sides of the light guide part 221 so that uniform light is emitted from the light guide part 221. The antenna bracket 230 may include a first seating part on which the antenna module 210 is seated on one side, and a second seating part on which the light source 225 is seated on the other side. The controller 180 is connected to the flexible substrate 228 and the controller 180 may control the light emitted through the light guide unit 221 by controlling the light source 225 when the user has a notice.

As the antenna radiator, the antenna radiator for the centimeter wave may be implemented using the metal part 104a of the side case 104 in addition to the patch antenna. When using the metal part 104a of the side case 104, since the side case 104 forms an external appearance, length cannot be adjusted freely. In order to match the resonant frequency of the antenna radiator with the frequency of a signal to be transmitted and received, the conductive pattern 215 connected to the metal part 104a may be further included. The conductive pattern 215 may be implemented in the form of a conductive wire formed on the flexible substrate, and may be used as an antenna for contacting the metal part 104a of the side case 104 to transmit and receive signals with the metal part 104a.

4 is a cross-sectional view of A-A and B-B of FIG. 1C. The light guide part 221 of the present invention emits light such that the light incident part 221b through which light is incident, the light exit part 221a through which light is emitted, and the light incident from the light incident part 221b are directed toward the light exit part 221a. It may include a reflecting portion 221c to reflect. In the present exemplary embodiment, the light exit portion 221a may be exposed to the outside and the light incident portion 221b may protrude in the left and right directions. The light source 225 for supplying light to the light incident portion 221b may be disposed on the left and right sides of the light incident portion 221b and the light source 225 includes a conductive material so that the signal emitted by the antenna module 210 is not disturbed. The antenna module 210 may be spaced apart (d).

The light guide part 221 reflects the light incident from the light incident part 221b through the light exit part 221a while reflecting the light from the light reflection part 221c and forms a pattern in the reflection part 221c. It may be guided to be reflected to the light exit portion 221a without exiting through the 221c.

As shown in FIG. 4, a reflective sheet 223 may be further provided between the antenna module 210 and the light guide portion 221, that is, the reflective portion 221c. The reflective sheet 223 may be formed by coating the opposite surface of the light emitting portion 221a of the light guiding portion 221, and a member having good reflection such as white or silver may be formed between the antenna bracket 230 and the light guiding portion 221. Can be intervened in Since the reflective sheet 223 is located in front of the antenna module 210, the reflective sheet 223 may include a non-conductive material so as not to disturb the signal emitted by the antenna module 210.

5 to 6 illustrate various embodiments of the light guide portion 221 of the present invention. In FIG. 2, the light guide portion 221 is exposed together with the non-metal portion 104b of the side case 104. In the embodiment of FIG. 5, the non-metal portion 104b is not exposed to the side of the mobile terminal 100. The size of the light exit portion 221a of the light guide portion 221 can be greatly enlarged so that the light guide portion 221 and the metal portion 104a form a boundary. FIG. 5A is a view of the light guide portion 221 from the outside, and FIG. 5B is a cross-sectional view thereof, and the light guide portion 221 may have a shape that is wider toward the outside.

When both the non-metal part 104b and the light guide part 221 are exposed to the outside, the boundary between the non-metal part 104b and the light guide part 221 further appears so that the light guide part 221 and the metal part 104a directly contact each other. When placed, the exterior design has a cleaner effect.

FIG. 6 is a further embodiment of the light transmitting part 222, and may include a light transmitting part 222 covering the light guiding part 221 without being directly exposed to the light guiding part 221. The light transmitting unit 222 may use a translucent material so that light is lightly output, or a light transmitting unit 222 having a color added to a surface where the light transmitting unit 222 and the light guide unit 221 contact each other.

The light guide portion 221 of the embodiment of FIG. 2 may further include a light transmitting portion 222 (FIG. In the case where the light guide portion 221 does not penetrate the non-metal portion 104b and the non-metal portion 104b covers the light emitting surface of the light guide portion 221, the non-metal like the light transmission portion 222. The portion 104b may include a translucent material.

7 and 8 are tables showing illuminance and luminance according to the shape of the light guide portion 221 and the presence or absence of the position reflecting plate of the light source 225 of the present invention. FIG. 7 illustrates performance when the light guide portion 221 has a uniform width, that is, when the light guide portion 221 of the shape shown in FIG. 2 is used, and FIG. 8 shows a light guide portion that is widened toward the outside as shown in FIG. 5. This table shows the performance when using (221).

Referring to FIG. 7, design 1 is an embodiment in which light sources 225 and light guides 221b of light guides 221 are spaced apart from each other, and an improvement 1 is light guides 221 and light guides 221 of light guides 221. 221b is disposed adjacent to each other, and Improvement 2 is an embodiment in which a reflective sheet 223 is added.

When the light incident part 221b and the light source 225 are spaced apart from each other, the amount of light incident on the light guide part 221 is relatively small. Therefore, the luminous flux and average illuminance luminance of the light guide portion 221 are both low, resulting in only 1.28% system efficiency. In particular, the illuminance difference between the center and both ends is large, making it difficult to emit uniform light.

When the light incident part 221b and the light source 225 are disposed adjacent to each other, the luminous flux, average illuminance brightness, etc. of the light guide part 221 are improved several times or more, and the system efficiency is also improved six times or more to 8.78%. Distribution of illuminance The illuminance difference at both ends and center is reduced, so that it can provide more uniform light than the existing design.

Improvement 2 is the addition of the reflection sheet 223, it can be seen that the overall performance is improved than the improvement 1 and the illuminance distribution is also more uniform. This is because a large amount of light is transmitted to the center portion due to the reflective sheet 223.

FIG. 8 is an embodiment using the light guide portion 221 of FIG. 5. Design 2 is an embodiment in which the light guide portion 221 and the light source 225 are separated from each other, and the improvement 1 uses the light source 225 and the light guide portion 221. The case of adjoining arrangements and the improvement proposal 2 show the case where the reflection sheet 223 is further provided.

As illustrated in FIG. 8, an inclined surface may be formed on the light guide part 221 having a shape that is wider toward the outside and the reflection part 221c so that the light incident from the light source 225 is reflected in the front direction. As shown in the embodiment of FIG. 7, since the light incident from the light incident part 221b is reflected by the reflecting part 221c and directed toward the light exiting part 221a, the luminous flux may be improved. However, when the area of the light output part 221a is larger than that of the embodiment of FIG. 7, the average illuminance and luminance are lowered when the same light source 225 is used. When the light source 225 and the light receiving portion 221b of the light guide portion 221 are disposed adjacent to each other (improved proposal 1), the efficiency is further improved, and the addition of the reflection sheet 223 to the reflection portion 221c further improves the efficiency.

9 illustrates another embodiment of the present invention. The light guide portion 221 may be integrally formed with the side case 104 in a double injection method. When the light guide portion 221 is formed separately, the non-metal part 104b may be coated to be processed so that the boundary with the metal part 104a does not appear clearly. Can not be coated.

In this case, as shown in FIG. 9, the side case 104 and the light guide portion 221 are coated at the same time, so that the boundary surface is covered, and thereafter, the light from the light exit portion 221a is emitted to the outside in a micropore or slit shape. The coating can be partially removed.

10 is a graph showing the performance of the antenna module 210 of the present invention. The light guide part 221 and the light source 225 show the performance with and without the antenna module 210 located outside. As shown in FIG. 10A, whether the light guide unit 221 is added or not, the difference does not affect the radiation performance of the antenna module 210 as a difference within an error range. 10B illustrates a beam pattern, and the difference according to the presence or absence of the light guide portion 221 is minute.

Therefore, even if the side case 104 portion from which the metal portion 104a has been removed for antenna radiation, as shown in the present invention, does not affect the antenna performance.

The light output unit is a part that emits light to inform the user of an event occurring in the mobile terminal 100, and may provide different information according to the light blinking number of flashing patterns, and the like. Information can be provided. For example, the color of light emitted through the light guide part 221 may be changed to indicate a communication state. If not connected, the red sensitivity is low, and if it is yellow, it can be displayed as white.

In addition, when a new event occurs, the user may easily know which event has occurred by changing colors. In particular, an event occurring in a state where the display unit is turned off can be identified by a user without knowing through the display unit.

For example, a yellow phone call when prompted, a green battery alert can provide other information in colors such as red. These events may be representative of the color of the icon of the associated application or may be specified by the user.

In addition, the light source 225 may be blinking to notify the user of the occurrence of an event. For example, you can blink within a few seconds of an event to get the user's attention. In the case of having a plurality of light sources 225, the light source 225 may be selectively blinked to provide other information.

As described above, the mobile terminal of the present invention can form an optical output unit by utilizing the non-metal region for securing the radiation region of the antenna module 210, so that the mobile terminal 100 due to the large size non-metal portion 104b. The impact on the appearance was minimal.

The above detailed description should not be construed as limiting in all respects but should be considered as illustrative. The scope of the invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the invention are included in the scope of the invention.
