The proximity sensor may be configured to output different proximity signals according to a distance between the proximity-touched pointer and the touch screen (hereinafter referred to as "proximity depth").

A distance at which the proximity signal is output when the pointer approaches the touch screen is referred to as a detection distance. In short, by using a plurality of proximity sensors having different detection distances, the proximity signals output from the proximity sensors are compared, .

In FIG. 3, for example, a cross section of a touch screen on which three proximity sensors capable of sensing three proximity depths is disposed is illustrated. Of course, proximity sensors that detect less than three or more than four proximity depths are also possible.

Specifically, when the pointer is completely in contact with the touch screen (d0), it is recognized as a contact touch. If the pointer is located on the touch screen at a distance less than the distance d1, it is recognized as a proximity touch of the first proximity depth.

If the pointer is located on the touch screen at a distance d1 or less and less than the distance d2, the pointer is recognized as a proximity touch of the second proximity depth. When the pointer is spaced apart from the d2 distance by more than d3 distance on the touch screen, it is recognized as a proximity touch of a third proximity depth. If the pointer is located at a distance d3 or more on the touch screen, it is recognized that the proximity touch is released.

Accordingly, the controller 180 can recognize the proximity touch as various input signals according to the proximity and proximity positions of the pointer to the touch screen, and perform various operation controls according to the various input signals.

FIG. 4 shows various GPS (Global Positioning System) satellites 300. These satellites 300 may track the location of some or all of the mobile terminals 100. Although two satellites are shown, it is apparent to those skilled in the art that the location information can be obtained from more or fewer satellites. Other types of location tracking techniques (e.g., location tracking techniques that may be used in place of or in addition to GPS technology) may be used. If desired, some or all of the GPS satellites 300 may be configured to separately or additionally support satellite DMB transmission.

During operation of the wireless communication system, the base stations 270 receive reverse link signals from a plurality of mobile terminals 100. The mobile terminals 100 may be busy, are sending messages, and are performing other communications. Each reverse link signal received by the base station is processed at the base station. The processed data is transmitted to the connected base station controller 275. The base station controller 275 provides call resource allocation and provides mobility management functionality including orchestration of soft handoffs between the base stations 270. [ ). The base station controllers 275 also transmit the received data to the mobile switching centers (MSCs) 280. The mobile switching center 280 provides additional routing services for interfacing with the public switched telephone network (PSTN) 290. Similarly, the public switched telephone network 290 interfaces with the mobile switching center 280 and the mobile switching center interfaces with the base station controllers 275. The base station controllers 275 in turn control the base stations 270 to transmit forward link signals to the mobile terminals 100.

5 is a flowchart of a mobile terminal according to an embodiment of the present invention.

As shown in the drawing, the controller 180 of the mobile terminal 100 according to an embodiment of the present invention may detect the remaining amount of the battery 195 (S10).

The battery 195 may be built in the mobile terminal 100 to supply power to the mobile terminal 100 while carrying the mobile terminal 100. The battery 195 may be charged by receiving power through the wired charging module 191 and / or the wireless charging module 193. The state of charge of the battery 195 may be detected through the battery level detection module 142 of the sensing unit 140.

The remaining battery detection module 142 may detect the amount of power charged in the battery 195. That is, when the maximum amount of power that can be charged in the battery 195 is 1, it means that the amount of power currently charged in the battery 195 can be detected. The battery level detection module 142 may measure the current power amount substantially in real time or at regular time intervals.

The wired charging module 191 may be a device used to charge the battery 195 by receiving power through a wired wire. For example, it may be a device that receives power from an outlet and supplies power to the battery 195.

The wireless charging module 193 may be a device used to charge the battery 195 by receiving power via wireless. When the battery 195 is in a charged state, the wireless charging module 193 may be different from the wired charging module 191 in that a wireless power line is formed between the outlet and the mobile terminal 100. The charging of the battery 195 through the wireless charging module 193 may be performed by a magnetic induction method, a magnetic resonance method, or the like.

Wireless charging using a magnetic induction method may refer to a method of transmitting power wirelessly using an electromagnetic induction method. The electromagnetic induction method may be a method of charging through a magnetic field induced between a primary coil transmitting electricity and a secondary coil receiving electricity.

The wireless charging using a magnetic resonant method may be a wireless charging method using a principle that causes the transmitting side and the receiving side to resonate at the same frequency. Magnetic resonance may be capable of wireless charging at a relatively long distance. Further, the transmitting side and the receiving side may be in a one-to-many relationship. That is, it means that a plurality of mobile terminals 100 can be charged at the same time.

In operation S20, the detected battery remaining amount and the reference remaining amount may be compared.

The remaining amount may mean an amount of power remaining in the battery 195. The remaining amount may be detected through the battery remaining amount detection module 142.

The reference residual amount may be a preset value. When the case where the battery 195 is fully charged is 1, the reference residual amount may be set to 0.5, 0.3, 0.1, or the like. The reference residual amount may be appropriately adjusted by the time of manufacture of the mobile terminal 100 or by the user's setting.

The reference residual amount may be a plurality. For example, with 0.5, 0.3, and 0.1 as the reference remaining amount, it means that a corresponding operation can be performed for each reference remaining amount.

If the remaining battery level is less than the reference remaining amount, the step (S30) of checking the point where the wireless charging is possible may proceed.

Wireless charging may be possible within a certain radius from the device performing the wireless charging function. This may be similar to wi-fi that can be used only within a certain radius from the access point (AP). In addition, in the case of wireless charging using a magnetic induction method, a point where wireless charging is possible may mean a point where an apparatus for providing a magnetic induction method is provided.

In operation S40, the display 151 may be selectively activated according to the distance between the remaining battery level and the wireless charging point.

As described above, the remaining battery level may be detected through the remaining battery level sensing module 142.

The distance from the wireless charging point may be calculated based on the location information obtained through the location information module 115. That is, it means that the current location of the mobile terminal 100 can be known based on the GPS signal acquired through the location information module 115. In addition, the information on the wireless charging point can be obtained through the mobile communication module 112, the wireless Internet module 113, the short-range communication module 114 and the like.

The controller 180 may selectively activate at least a portion of the display 151 based on a distance between the remaining battery level and the point where the wireless charging is possible.

Activation of at least a portion of the display 151 means that the area displaying the image may be limited. For example, when the total area of the display 151 is 100%, it means that the image may be displayed in all the areas or the image may be displayed only in the 50% area. Furthermore, the position of the image displayed on the 50% portion may also be selectively selected. For example, it means that the image can be displayed on the center portion of the display 151 or the image can be displayed on the left or right side away from the center portion of the display 151.

Activation of at least a portion of the display 151 may be performed sequentially with respect to the plurality of reference residual amounts. For example, when the battery 195 is fully charged as 1, the reference residual amount may be set to 0.5, 0.3, and 0.1. The controller 180 displays an image on the 50% region of the display 151 when the battery level is 0.5, displays an image on the 30% region of the display 151 when the battery level is 0.3, and the battery level is 0.1. , The image may be displayed on the 10% area of the display 151.

Activation of at least a portion of the display 151 may be performed based on a distance between the remaining battery level and the point at which wireless charging is possible. For example, when the battery level is less than or equal to the reference level, the controller 180 may display an image only on 50% of the display 151. Therefore, the effect of reducing the consumption of power charged in the battery 195 can be expected. In addition, when the distance from the wireless charging point is farther than the reference distance, the controller 180 may display an image only below a predetermined area of the display 151. Therefore, it can be expected that the power consumption is reduced while moving to the point where the wireless charging is possible.

Activation of at least a portion of the display 151 may include a case of adjusting the brightness of the display 151. For example, when the remaining battery is low and the distance from the wireless charging point is far, it means that the brightness of the display 151 can be darkened.

By selectively activating at least a part of the display 151 according to the remaining amount of the battery and the distance between the points where the wireless charging is possible, the power charged in the battery 195 may be effectively used.

6 is a graph showing a change in the remaining battery capacity over time.

As shown in the drawing, power charged in the battery 195 of the mobile terminal 100 may be reduced by using the mobile terminal 100.

In the process of reducing the power charged in the battery 195, the remaining amount of the battery 195 becomes 70%, 50%, 30%, 10% of the state in which the battery 195 is fully charged, t1, t2, t3, There may be a time t4.

7 is a diagram showing a wireless charging possible region on a map.

As shown, the mobile terminal 100 may be located at the point P. The location of the mobile terminal 100 may be calculated through the location information module 115.

In the vicinity of the mobile terminal 100, there may be a point where wireless charging is possible. For example, A1 to A4 may be located. Information about A1 to A4 may be obtained through the mobile communication module 112, the wireless internet module 113, the short range communication module 114, and the like.

The information on A1 to A4 includes information on the location of A1 to A4, information on the range of wireless charging available through A1 to A4, information on the wireless charging strength of A1 to A4, and information on A1 to A4 wireless charging efficiency. And the like.

Knowing the information on the point P, which is the current location of the mobile terminal 100, and the information on the points A1 to A4, which are wireless charging points, the controller 180 can calculate a distance from the wireless charging point.

FIG. 8 illustrates a process in which the mobile terminal of FIG. 5 selectively activates a display.

As shown in the drawing, the mobile terminal 100 according to an embodiment of the present invention may selectively activate the display 151.

8A illustrates a case where the power charged in the battery 195 is higher than the first reference remaining amount. In this case, the controller 180 can cause the display 151 to be in the first state. The first state may be a state in which the display 151 is relatively bright. The brightness of the display 151 may be adjusted through the brightness of the back light. The remaining charge of the battery 195 may be displayed on the battery indicator BI.

8B may be a case where the power charged in the battery 195 is lower than the first reference remaining amount and higher than the second reference remaining amount. In this case, the controller 180 can cause the display 151 to be in the second state. The second state may be a state in which the display 151 is less bright than the first state.

FIG. 8C illustrates a case where the power charged in the battery 195 is lower than the second reference remaining amount and higher than the third reference remaining amount. In this case, the controller 180 can cause the display 151 to be in the third state. The third state may be a state in which the display 151 is less bright than the second state.

FIG. 8D may be a fourth state in which the battery 195 is being charged. If the battery 195 is being charged, the controller 180 can cause the display 151 to be in a first state or a brighter state.

9 is a graph illustrating a process of changing the light amount of the mobile terminal of FIG. 5.

As shown in the drawing, in the mobile terminal 100 according to an embodiment of the present invention, the brightness of the display 151 may vary according to the remaining amount of the battery 195. For example, when the maximum brightness of the display 151 is 100%, the brightness of the display 151 may be 70% to 10% as time passes from t1 to t4. In this case, the time points t1 to t4 may correspond to the time points t1 to t4 in FIG. 6. That is, it may be a point in time when the remaining amount of the battery 195 becomes 70% to 10%.

10 is a diagram illustrating a wireless charging area entry process of a mobile terminal according to one embodiment of the present invention.

As shown in the drawing, the mobile terminal 100 according to an embodiment of the present invention may selectively activate the display 151 as it enters an area where wireless charging is possible.

The mobile terminal 100 may be in the first position P1. The first location P1 may be outside of an area where wireless charging is possible. That is, when it is in the first position P1, it means that charging using wireless charging may not proceed. In this state, the controller 180 may perform a control operation to minimize the use of the battery 195 of the mobile terminal 100. For example, as described above, it means that an operation such as reducing the amount of light of the display 151 or reducing the display area of the display 151 may be performed.

The mobile terminal 100 may be in the second position P2. The second location P2 may also be outside of an area where wireless charging is possible. That is, similarly to the first position P1, the charging using the wireless charging may not be performed in the second position P2. However, unlike the first position P1, the second position P2 may be a point closer to the third position P3, which is an area in which the mobile terminal 100 can be wirelessly charged. In the case of approaching the third position P3, which is an area where wireless charging is possible, the controller 180 may enlarge the light amount, the display area, etc. of the display 151 at the first position P1.

The mobile terminal 100 may be in the third position P3. The third location P3 may be inside of an area where wireless charging is possible. When wireless charging is performed at the third position P3, the controller 180 may maximize the light intensity, the display area, and the like of the display 151.

11 is a diagram illustrating a display display according to a distance from a wireless charging area and a charging state of a mobile terminal according to an embodiment of the present invention.

As shown in the drawing, in the mobile terminal 100 according to an embodiment of the present invention, the display state of the display 151 may be changed according to the distance from the wireless charging area.

As illustrated in FIG. 11A, the controller 180 may display an image only in the first area DA1 of the display 151. The first area DA1 may be a smaller area than the entire area of the display 151. The display of the image in the first area DA1 may be when the mobile terminal is in the first position (P1 of FIG. 10). For example, when the remaining amount of the battery 195 is less than or equal to a certain level and the distance to the chargeable area is far, the image may be displayed only in the first area DA1.

As illustrated in FIG. 11B, the controller 180 may display an image only in the second area DA2 of the display 151. The second area DA2 may be a smaller area than the entire area of the display 151 but wider than the first area DA1. When the image is displayed in the second area DA2, the mobile terminal 100 may be in the second position (P2 of FIG. 10). For example, when the remaining amount of the battery 195 is less than a certain level but the distance to the chargeable area is relatively close, it means that the image may be displayed in the second area DA2.

As illustrated in FIG. 11C, the controller 180 may display an image only in the third area DA3 of the display 151. The third area DA3 may be an entire area of the display 151. When the image is displayed in the third area DA3, the mobile terminal 100 may be in the third position (P3 of FIG. 10). If the wireless charging is in a third position (P3 of FIG. 10), the wireless charging of the mobile terminal 100 may be possible. Accordingly, the image may be displayed on the entire surface of the display 151 regardless of the remaining amount of the battery 195.

12 is a diagram illustrating a volume change according to a distance from a wireless charging area and a charging state of a mobile terminal according to an embodiment of the present invention.

As shown in the drawing, the controller 180 of the mobile terminal 100 according to an embodiment of the present invention may change the volume of the output volume according to the distance from the wirelessly chargeable area. If D1 is closer to the wireless charging area than D2, D1 outputs the volume set by the user. D2 outputs 0.1 times the volume set by the user. have.

The controller 180 may adjust the output of the mobile terminal 100 based on not only the distance from the wirelessly chargeable area but also other conditions. That is, the horizontal axis of FIG. 12 indicates that the horizontal axis of FIG. 12 may be replaced by the distance to the region where the wireless charging is possible, the remaining amount of the battery 195, and the like. For example, when the remaining amount of the battery 195 is less than the reference remaining amount, it means that the volume can be reduced.

13 and 14 are views illustrating display displays according to a distance from a wireless charging area and a charging state of a mobile terminal according to an embodiment of the present invention.

As shown in these figures, the controller 180 of the mobile terminal 100 according to an embodiment of the present invention may selectively activate and / or deactivate a specific area of the display 151. The display 151 may display a qwerty keyboard for receiving text. The controller 180 may selectively activate / deactivate a portion of the display 151 based on factors such as the remaining amount of the battery 195 and / or the distance to the wireless charging region.

The area to be selectively activated / deactivated may be related to where the information to be transmitted to the user is located. For example, information received and newly output as a message, information input by the user, and the like may be information to be delivered to the user. On the contrary, in the case of information that is already output or information additionally added to the information to be transmitted, information that has little need to be transmitted to the user may be information. The controller 180 may selectively activate a portion on which information to be transmitted to the user is displayed based on such a criterion.

As illustrated in (a) of FIG. 13, the controller 180 may activate the first area DA1 at the moment a character is input. That is, the portion except for the first area DA1 may be inactivated or the backlight may be turned off. Even if portions other than the first area DA1 are darkened or deactivated, the user may input characters using the QWERTY keyboard displayed in the activated first area DA1.

As shown in FIG. 13B, the controller 180 may activate the second area DA2. That is, it means that the user can activate an input window area in which the user actually inputs a character.

As shown in FIG. 13C, the controller 180 may activate the third area DA3. That is, it is possible to activate the area in which the search result is displayed.

As shown in FIG. 13D, the controller 180 may activate the fourth area DA4, that is, only the most optimized result portion of the search results may be activated.

The controller 180 may not only fixedly activate and / or deactivate a specific area of the display 151 but also activate and / or deactivate an optimized point according to an operation state of a corresponding application.

As shown in FIG. 14A, when a message is received, the controller 180 can selectively activate only a part thereof.

As shown in (b) of FIG. 14, the controller 180 may selectively activate only the telephone number portion of the counterpart who is trying or making a call.

As illustrated in (c) of FIG. 14, the controller 180 may selectively activate only the photo part of the counterpart who attempts or makes a video call.

15 and 16 illustrate a method for displaying a wireless charging area of a mobile terminal according to an embodiment of the present invention.

As shown in these drawings, the controller 180 of the mobile terminal 100 according to an embodiment of the present invention can inform the user of information on where the wirelessly charged area is located.

As shown in FIG. 15A, a user may be photographing an image using the camera 121. In addition to displaying an image on the display 151, an indicator (IC) indicating a wireless chargeable area may be displayed. In addition, along with the indicator IC, information on which direction the wireless charging region is located may be displayed with respect to the current point where the mobile terminal 100 is located.

As shown in FIG. 15B, a map may be displayed on the display 151. On the map, first to fourth indicators IC1 to IC4 indicating the current location P of the mobile terminal 100 and a wirelessly chargeable location around the current location P may be displayed.

The first to fourth indicators IC1 to IC4 may also display the charging efficiency at the corresponding wirelessly chargeable positions. For example, it means that the charging efficiency of the device located at the point can be visually displayed by changing the color or changing the shape of the indicator.

As illustrated in (a) to (c) of FIG. 16, the map MI indicating a location where wireless charging is possible may be displayed in various forms. That is, the map may be displayed so as not to disturb the display of the currently running application as much as possible.

17 to 19 illustrate an operation of a mobile terminal according to another embodiment of the present invention.

As shown in these drawings, the mobile terminal 100 according to another embodiment of the present invention may be operated by a gesture operation in a state in which the wireless charging cradle 300 is mounted.

As illustrated in FIG. 17, a user may control the mobile terminal 100 through a gesture input using a hand H and / or a finger F in front of the mobile terminal 100.

When the user performs a gesture operation by using the hand H and / or the finger F, the operation may be photographed through the camera 121 located in the front of the mobile terminal 100. The controller 180 may execute a function corresponding to the corresponding gesture operation through image analysis of the captured gesture operation.

Control of the mobile terminal 100 through a gesture operation may be useful when the mobile terminal 100 is mounted on the contactless wireless charging cradle 300. When placed on the wireless charging cradle 300, the mobile terminal 100 may be located to correspond to the preset position and direction for optimal charging. While being located in this way, when the display 151 or the like is touched to operate the mobile terminal 100, the mobile terminal 100 may move. Therefore, while being located on the wireless charging cradle 300, it is possible to effectively charge by allowing the mobile terminal 100 to be controlled by the gesture operation.

As shown in FIG. 18, when the mobile terminal 100 is mounted on the wireless charging cradle 300, an image of the display 151 may be changed to correspond to the mounting direction. For example, when the mobile terminal 100 is mounted vertically, the image is displayed in the vertical direction, and when the mobile terminal 100 is mounted horizontally, the image may be displayed in the horizontal direction. Furthermore, the sound output module 152 may output a sound corresponding to the image.

As shown in FIG. 19, the mobile charging cradle 200 may be equipped with a mobile terminal 100. In order to allow the mobile terminal 100 to be mounted at an optimal position, the coupling guide 203 and the seating portion 202 may be provided in the wireless charging cradle 200.

The coupling guide 203 may allow the main body of the mobile terminal 100 to be naturally coupled to the proper position of the wireless charging cradle 200.

The seating part 202 may allow charging to proceed without shaking the main body of the mobile terminal 100 coupled to the home position.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention. Accordingly, such modifications or variations are intended to fall within the scope of the appended claims.
