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 of an object approaching a predetermined detection surface or an object existing in the vicinity of the detection surface without mechanical contact using an electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen. The proximity sensor 141 has a longer life than the contact type sensor and its utilization is also high.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. 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, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor senses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, do.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, etc. of a touch object to be touched on the touch screen on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, 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 transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object, which touches the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera 121, a photosensor, and a laser sensor. The camera 121 is a kind of camera sensor.

The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The cover side part protrudes from the edge of the main surface of the cover rear part 210 facing the rear surface of the terminal so as to surround the side surface of the terminal. More specifically, the cover side portion may protrude in a direction perpendicular to the main surface, and may be formed to surround a part of the side surface or to surround the side surface as a whole.

The connecting portion 230 may protrude outward from the edge of the cover rear portion 210 to connect the cover rear portion 210 and the cover front portion 220. [ The connection portion 230 may have a narrow width so as to be easily bent and the cover front portion 220 may be rotated to cover the display portion 151 using the warp of the connection portion 230. [ In this case, the connection part 230 may be provided with a support tab that is bent at one side of the cover rear part 210 and closely attached to one side of the corner of the mobile terminal.

The connection portion 230 may be integrally formed with the cover front portion 220 and may be coupled to the cover rear portion 210. In this case, the connection part 230 may be formed of the same material as the cover front part 220, and may extend from one side of the cover front part.

As another example, the connection portion 230 may be integrally formed with the cover rear portion 210 and may be coupled to the cover front portion 220. In this case, the connection portion 230 may be formed of the same material as the cover rear portion 210 and may extend from one side of the cover rear portion 210.

2B shows a state in which the cover 200 covers the display unit 151 of the mobile terminal.

In the covered state, since the mobile terminal 100 and the cover 200 are shaped like a diary, the portability of the user is improved. Also, since the cover 200 serves as a protective cover for covering the mobile terminal 100, the mobile terminal 100 can be more safely protected from an external impact or stimulus.

The cover rear portion 210 and the cover front portion 220 are arranged to be parallel to each other in a covered state and the connection portion 230 is formed in a part of the gap formed between the cover rear portion 210 and the cover front portion 220 As shown in Fig. In this case, the remainder of the gap may be filled by the provision of the cover side portion.

Referring to this figure, the cover 200 is formed to expose the time information of the display unit 151 to the outside in a state that the cover unit 151 is covered. More specifically, referring to FIG. 2B, the cover front portion 220 may include a window portion 240, and the window portion 240 may be a region made of a light-transmitting member. The window part 240 is formed to transmit the time information of the display part 151 on the outer surface of the window part 240 by light transmittance.

The window unit 240 is overlapped with the display unit 151 for outputting the time information. More specifically, the window part 240 may be positioned at an upper portion of the front surface of the display part 151 in a state that the cover front part 220 covers the display part 151. According to this structure, the user can recognize icons, texts, images, and the like output from the display unit 151 through the window unit 240 from the outside.

In addition, in the terminal of the present invention, when an event occurs in the terminal while the cover front is closed and the display unit 151 is inactivated, a portion of the display unit corresponding to the area exposed by the window unit 240 is referred to as And the cover 200 outputs the notification light to the outside by using the light generated by the activation of the display unit 151. In this case, among the areas of the display unit, a window may be activated so that a separate screen is displayed at a portion exposed to the outside. For this control operation, the cover 200 is provided with a mechanism for collecting light output from the display unit 151 to generate a specific pattern. Hereinafter, this pattern generating mechanism will be described in more detail.

Figure 3 is an exploded view of the cover 200 of Figure 2a, and Figure 4a is a cross-sectional view taken along line A-A of Figure 2b.

3 and 4A, a window hole 221 is formed in the cover front portion 220 and the window portion 240 (see FIG. 2B or FIG. 4A) is formed to cover the window hole 221 And a window 241. The window hole 221 may be located at a longitudinal center line of the display unit 151 of the terminal or a longitudinal center line of the front surface of the terminal while the cover 200 covers the terminal. However, the present invention is not limited thereto, and the window part 240 may have a structure in which only the window hole 221 is formed without the window 241.

The window 241 may have an outer surface formed on the same plane as one surface (outer surface: a surface exposed to the outside in a covered state) of the cover front portion 220, and may be made of glass, Transparent urethane, transparent synthetic resin, or the like.

The cover front part 220 is provided with a seating surface 222 on which the window 241 is seated and the seating surface 222 may be a surface having a height difference with respect to the outer surface of the cover front part, And is formed so as to surround the window hole 221.

Referring to FIGS. 3 and 4A, the cover 200 includes a guide unit 250 mounted on the cover front unit 220. The guide unit 250 guides the light output from the display unit 151 of the terminal to the window unit 240.

The guide part 250 covers at least a part of the display part 151 in a state that the cover 200 covers the display part 151. When the light outputted from the display part 151 is incident, To the specific region of the window portion 240. [ A specific pattern may be formed outside the cover 200 by the diffusion of light.

In this example, a structure for forming a circular pattern along the rim of the window part 240, more specifically, along the edge of the window 241, is disclosed. For this, the guide part 250 may be formed to surround the outer circumference of the window part 240. For example, the window part 240 is circular, and the window 241 may be circular. The guide part 250 may be formed to be larger than the window part 240 and cover the periphery of the window part 240.

The guide portion 250 may include a guide sheet 251, for example. The guide sheet 251 diffuses light incident on a part of one surface and emits light in a wider area on the other surface. As an example, the guide sheet may be a diffusion sheet or a diffusion film.

In the guide sheet, a diffusion layer is formed on one side of the base film by coating to diffuse the light. Alternatively, as shown in FIG. 4B, protrusions may be formed inside the guide sheet 251a.

3 and 4A, the guide sheet 251 covers a part of the window part 240, and the guide sheet 251 is provided with a through hole (not shown) corresponding to the window part 240, (252) are formed. For example, the center of the through hole 252 coincides with the center of the window 241 so that the overlapped portion overlapped by the window 241 in the guide sheet 251 forms an annular band, The size of the through hole 252 may be smaller than the window 241. With this structure, one surface of the guide sheet 251 can be the seating surface 222.

In this case, the window part 240 may include a coupling part (not shown) for coupling the seating surface 222 and the window 241. As an example of this, the engaging portion (not shown) may be an adhesive or a double-sided tape applied to only a part of the seating surface 222. As another example, it is also possible that a light-transmitting adhesive is applied to the whole of the seating surface 222.

According to the illustrated embodiment, the cover front portion 220 is formed with a recess portion 223 which is recessed along the thickness direction and receives the guide sheet 251.

The recess portion 223 may be formed on the other surface of the cover front portion 220 (inner surface, opposite surface of the cover front surface 220). In this case, the window hole 221 may be formed at the bottom of the recess portion 223. The guide sheet 251 may have a thickness corresponding to the depth of the recess portion 223 so that the guide sheet 251 is disposed on the same plane as the other surface of the cover front portion 220 .

In this case, the control unit of the terminal may illuminate an area covered by the guide seat portion of the display unit, so that light emitted from the guide unit is guided when the event is generated.

Also, the terminal is configured to detect opening / closing of the display unit 151 by the cover 200. For example, a magnet M may be mounted on the cover 200 and a sensor corresponding to the magnet may be mounted on the terminal. The sensor may be, for example, a Hole IC sensing a magnetic field. However, the present invention is not limited thereto. For example, it is possible to recognize that the cover is covered by using a proximity sensor, or to recognize that the cover is covered by using the illuminance sensor. The sensing of the opening and closing of the display unit 151 by the cover can be similarly applied to the modification of the present invention or other embodiments.

In this way, when an event occurs in the covered state, the display unit 151 is activated in order to light the covered area. In this case, the display portion may be activated globally or only a portion (e.g., a portion corresponding to the region of the guide sheet) may be activated and the remaining region may be deactivated. Light emitted from the display unit is incident on the guide sheet 251 by the activation, and the incident light is diffused into the overlapping portion and externally emitted. The light emitted to the outside becomes a notification light, and since the overlapping portion is an annular band, the announcement light forms an annular band. Light can be output for a certain time with maximizing the amount of light, and the user can recognize whether an event has occurred by viewing the light in the form of an annulus at this time. In this case, the intensity of the light can be controlled by the user.

The pattern generating mechanism according to the present invention described above may be configured with another example structure, and such another embodiment or modification will be described below. In the modifications or embodiments described below, the same or similar reference numerals are given to the same or similar components as those of the previous example, and the description is replaced with the first explanation.

The cover front part 320 is formed of a light transmitting material and transmits light output from the display part. In addition, when the light is incident on the cover front portion 320, the incident light may be diffused inside. As an example, the cover front portion 320 may be made of a material such as transparent silicone, transparent urethane, transparent synthetic resin, or the like.

A window hole 321 is formed in the cover front portion 320. However, in this example, the window hole 321 may be a through hole not covered by the window. The cover 300 can expose the time information of the display unit 151 to the outside while the display unit 151 is covered by the window hole 221.

5 and 6, the pattern generating mechanism in this example can be implemented by the structure of the blocking layer 360. [

The cover layer 360 is made of an opaque material and is formed on the outer surface of the cover front portion 320. The blocking layer 360 may be a printing layer formed by printing or a vapor deposition layer formed by vapor deposition.

The cover layer 360 is disposed to cover the cover front portion 320 so that an opaque region 371 is formed on the outer surface of the cover 300. In this case, the blocking layer 360 is formed so as not to cover the edge of the window hole 321 so that a transparent region 372 is formed along the edge of the window hole 321. In this case, both the opaque region 371 and the transparent region 372 become a diffusion region where light is diffused, and light is emitted to the outside from the transparent region 372. That is, the transparent region 372 has an annular band shape along the edge of the window hole 321, and thus the transparent region 372 can be referred to as a decoration portion.

According to the structure of the present exemplary embodiment, when an event occurs in the terminal, the display unit 151 is activated, light output from the display unit is incident on the transparent body of the cover front portion, and the incident light is transmitted through the transparent body And is emitted to the outside from the transparent region 372. The light emitted to the outside becomes a notification light, and since the transparent region 372 is an annular band, the announcement light forms an annular band.

The seating surface 422 may be a surface having a height difference with respect to the outer surface of the front surface of the cover, And is formed so as to surround the window hole 421.

7 and 8, the cover 400 includes a border area 480 for outputting light output from the display unit 151 of the terminal to the outside. For this purpose, the rim area 480 may be formed of a light transmissive material. The border area 480 may be a transparent area and the remaining area of the cover front part 420 excluding the window part 440 and the border area 480 may be an opaque area.

The cover 400 includes a guide unit 450 for guiding light emitted from the display unit 151 to the edge region 480 at least partially exposed to the outside in a state that the display unit 151 is covered, .

The guide part 450 diffuses incident light as a part of the guide part 450 and emits the light from another part. As an example, the guide portion 450 may include a diffusion sheet or a diffusion film.

More specifically, the guide part 450 is formed such that at least a part of the guide part 450 is exposed from the inner surface of the cover front part 420, and the exposed part covers the display part 151 in the covered state. Also, the guide part 450 is formed so that at least a part of the guide part 450 is overlapped with the edge area 480. With this structure, the guide unit 450 guides the light output from the display unit 151 of the terminal to the edge region 480.

As shown in this example, the rim area 480 of the cover front part 420 may be made of a transparent material and the rest may be made of an opaque material. In this case, a pattern generating mechanism can be implemented by a structure in which the diffusion sheet covers the display portion 151 together with the rim region 480. [ However, the present invention is not limited thereto. For example, the diffusion sheet protrudes from the edge of the cover front part 420 to be partially exposed to the outside, and a structure that emits light in the protruded part is also possible Do. As another example, the cover front part 420 may be formed of a transparent material, but a cover layer may be formed on one surface of the cover front part except for the edge area.

Further, the cover of the present invention is configured to detect the touch input of the user in response to the pattern generation. Hereinafter, such a structure will be described. 9A and 9B are conceptual diagrams of another embodiment of the present invention.

According to the illustration, the cover 500 has a window portion 540 and a touch sensing portion 590. More specifically, the window unit 540 is an area for exposing the time information of the display unit to the outside, and the touch sensing unit 590 may be an area for sensing the touch input of the user.

For example, in order to form the touch sensing unit 590, the cover front 520 of the cover 500 may have different materials according to the area. For example, the touch sensing unit 590 may be formed of a conductive material to sense a touch input to the touch sensing unit 590 on the touch screen of the terminal. In this case, other portions of the cover front portion 520 may be formed of a nonconductive material.

As another example, the material of the cover front part 520 is the same, but the touch sensing part 590 may include a conductive pigment.

As another example, the material of the cover front part 520 is the same, but a conductive material is applied to the touch sensing part 590, and the touch sensing part is formed of an elastic material, .

As another example, the cover front portion 520 may have a thickness different from that of the other portions of the touch sensing portion 590. For example, the touch sensing portion 590 may be configured to be thinner than other portions. For this, the touch sensing unit 590 may be formed to be recessed on the outer surface of the cover front unit 520.

Referring to FIG. 9B, the touch sensing unit 590 may include a separate touch sensor (not shown) mounted on the cover front unit 520. In this case, when the cover is mounted on the terminal, a wiring line 591 for electrically connecting the touch sensor (not shown) to the control unit of the terminal may be provided.

The wiring line 591 extends from the touch sensor of the cover front portion 520 and extends to the rear portion of the cover through the connection portion. A connection terminal 591a connected to the wiring line 591 is provided on the cover rear portion of the cover 591. The terminal body is provided with a connection terminal .

The terminal body and the cover described above can provide a new user interface to the user using the cover opening / closing, touch input, pattern generation, and the like. These user interfaces will be described in more detail below.

3, 5, 7, 9A, and 9B, when an event occurs in a state in which the display unit 151 is inactivated, the display unit 151 displays, And the cover 200 diffuses the light generated by the activation of the display unit 151 and outputs the notification light to the outside. At least a part of the display part activated here may be, for example, a window area or an area where the guide part is disposed. The notification light may be emitted to the outside through a guide sheet including a diffusion material provided in a guide unit 250 formed to cover the periphery of the window unit 240. Here, the at least a part may be an area corresponding to a position of the window disposed in the cover as described above, or a border area of the window.

In order to perform such a control operation, the cover 200 is provided with a mechanism for collecting the light output from the display unit 151 to generate a specific pattern. The description of the pattern generating mechanism will be described with reference to FIGS. 2A, 2B, , The description of Figs. 4A and 4B will be omitted.

Hereinafter, a method of outputting information when an event occurs on the mobile terminal using the pattern generation mechanism will be described in detail with reference to the accompanying drawings. FIG. 10 is a flowchart illustrating a method of providing a user interface for notifying an occurrence of an event using a cover in a mobile terminal according to the present invention. FIGS. 11A and 11B are conceptual diagrams for explaining FIG.

When an event occurs in the mobile terminal according to the present invention (S710), the control unit 180 detects whether the display unit is blocked by the cover (S720).

Herein, the 'event' refers to a case where an operation that affects the operation of at least one application installed in the mobile terminal occurs, a change occurs in information stored in a database (or a data file) associated with the at least one application, It means that data is transmitted or transmitted to an external terminal or an external network (or an external server) through the at least one application. For example, 'call reception' or 'message reception' may be an example of the event.

Furthermore, this 'event' may occur in association with the operation of the mobile terminal or the state of the mobile terminal, in addition to that occurring in association with the application installed in the mobile terminal. For example, if the battery charge amount of the mobile terminal is less than a preset reference value, the mobile terminal may generate an event to inform the battery amount information. As another example, an event may occur even when the wireless communication unit 110 of the mobile terminal moves out of the wireless communication network or enters the wireless communication network. As such, an event can occur in various cases relating to the driving, operation, and status of the mobile terminal, and in this specification, the type of event is not bound to the examples listed above, and there is information to inform the user at the mobile terminal, It can be understood that an event has occurred when it is generated or received.

Whether or not the display unit is blocked by the cover 200 when an event occurs can be detected in various manners. For example, the cover 200 is equipped with a magnet, and the mobile terminal is provided with a magnet The sensor can be mounted. Here, the sensor may be a Hole IC sensing a magnetic field. Accordingly, the control unit 180 can detect whether the display unit 151 is covered by the cover 200, based on a signal sensed by the sensor corresponding to the magnet. As another example, the mobile terminal can recognize whether the cover 200 is covered by the display portion 151 by using a proximity sensor or an illuminance sensor.

On the other hand, if it is determined in operation S710 and S720 that the event occurs in the mobile terminal and the display unit is covered by the cover, the notification light indicating that the event has occurred is output to the border area of the window unit provided in the cover (S730).

More specifically, the control unit 180 generates light by lighting the display area of the display unit corresponding to the boundary area of the window unit. The generated light is guided by the diffusion sheet (or diffusion material) included in the guide seat portion, and is emitted to the outside in the boundary region of the window portion. 3, the notification light may be embodied by a guide sheet 251 included in the guide unit 250 and diffusing light incident on a part of the surface and emitting light in a wider area on the other surface, as shown in FIG. 3 have. Here, the guide sheet may be a diffusion sheet or a diffusion film.

On the other hand, such a notification light can be formed in the boundary region of the window portion by the diffusion member without the guide portion 250.

In the present invention in which the pattern generating mechanism is combined with the cover having the structure as described above, when an event occurs in a state that the display unit 151 is covered with the cover 200, an area covered by the cover 200 The display unit 151 is activated to light up. The light output from the display unit 151 is incident on the guide sheet 251, and the incident light is diffused into the overlap portion and externally emitted. In other words, the light emitted to the outside becomes the annunciation light in the boundary region of the window unit 240 in this manner.

On the other hand, in a state in which the notification light is output in step S730, the event information corresponding to the generated event is output based on a touch of a preset method applied to one area 151 'of the display unit (S740).

Here, the event information may be brief information including at least one of the name of the event-generated application and the graphic image representing the application, detailed information including the content of the generated event, and the like. It is also possible that the event information is output from one area 151 'of the display unit at the same time that the notification light 310 is output.

If it is determined in step S720 that the display unit 151 is not covered by the cover, event information may be directly output to the display unit 151. [ In this case, the event information may be output through a pop-up window. Further, the manner in which the event information is output may be variously changed according to the setting of the mobile terminal.

More specifically, referring to the accompanying drawings, as shown in FIG. 11A, when an event occurs in the mobile terminal, when the display unit 151 is covered by the cover 200, The notification light 310 is outputted in the boundary region of the light source unit 240. [ That is, when an event occurs in the mobile terminal, when the cover unit 200 detects that the display unit 151 is covered by the cover 200, the control unit 180 displays the notification light 310 in the border area of the window unit 240 At least one area of the display unit 151 is activated. Accordingly, the user can recognize that an event has occurred on the mobile terminal through the notification light 310 even if the display unit 151 is covered with the cover 200. [

In the mobile terminal according to the present invention, when an event occurs in the mobile terminal in a state that the display unit 151 is covered with the cover 200, the notification light 310, as shown in FIG. 11A, As shown in FIG. 11 (b), in addition to the method of displaying the image in the border area of the window part 240, through one area 151 'of the display part exposed to the outside by the window part 240, And can output event information related to the generated event. Here, the event information may be brief information including at least one of the name of the event-generated application and the graphic image representing the application, detailed information including the content of the generated event, and the like. The event information can be output from one area 151 'of the display unit at the same time that the notification light 310 is output. Alternatively, the event information may be output after the notification light is output, based on a predetermined type of touch that is applied to one area 151 'of the display unit while the output of the notification light is maintained . In addition, the event information may be output based on a predetermined type of touch that is applied to one area 151 'of the display unit after the output of the notification light ends. That is, the event information can be output at various time points.

Here, the preset touch may be a slide touch that is continuous from one point to another, a tap touch that places one area 151 'of the display unit at least once.

In the present invention, while the event information is displayed, the display unit 151 may be controlled to output the notification light 310 together, or the output of the event information, the display, and the notification light 310 may be independently controlled . On the other hand, the notification light 310 may be displayed only for a predetermined time, and then the output may be terminated. Also, if the generated notification event is not acknowledged, the notification light 310 is displayed at the reference time interval, and then the output is ended after the display is performed for the predetermined time, or the output is continuously maintained until the event is confirmed .

In addition, although not shown, when event information corresponding to simple information is displayed in one area 151 'of the display unit, an event corresponding to the detailed information is displayed on the basis of touching one area 151' More information can be output.

11 (a) and (b), the controller 180 controls the operation of the cover 180 in order to output the notification light 310 at the boundary of the window unit 240 by being guided by the guide sheet 251, The area 310a (see FIG. 11B) overlapped with the display area heavy-duty guide sheet 251 of the display unit 151 covered with the light guide plate 240 can be activated to emit light. Here, the display area to be activated is not necessarily overlapped with the guide sheet 251 exactly.

That is, the display unit 151 may be divided into an activation region 310a corresponding to a portion overlapping the guide sheet 251 and a deactivation region corresponding to a portion not overlapping the guide sheet 251 .

When the display unit 151 is covered by the cover 200, the notification light 310 is displayed on the memory 170 in the boundary area of the window unit 240 among the display areas of the display unit 151 Information on the light emitting region to be emitted may be stored in advance and stored. The information on the light emitting area may be information on a position where the window part 240, the guide sheet 251, and the like are provided in the cover 200. Accordingly, when an event occurs in the mobile terminal while the display unit 151 is covered by the cover 200 based on the information about the light emitting region, the controller 180 emits the light emitting region, The notification light 310 may be formed in the boundary region of the light guide plate 240.

On the other hand, the control unit can recognize the type of the cover currently mounted on the terminal, based on the position of the magnet mounted on the cover 200. In the memory 170, information on the recognized cover may exist in advance, and information on the cover may include position information and shape information of the window disposed on the cover. The control unit 180 may determine which area of the display unit to emit light in order to form the notification light 310 in consideration of the information about the cover. The shape of the window portion may vary widely, and may be a circle, a square, a triangle, or the like.

On the other hand, the control unit 180 can recognize the cover on which the magnet is mounted by using a hole IC that senses a magnetic field.

Meanwhile, in the mobile terminal according to the present invention, it is possible to provide more specific information on an event by variously controlling the notification light formed at the boundary of the window part according to the type or number of events. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. 12A, 12B, and 12C are conceptual diagrams for explaining a method of notifying an occurrence of an event in a mobile terminal according to the present invention.

The output method (for example, color or lighting method) of the notification light 310 output from the boundary area of the window unit 240 as described above may be performed by the color or lighting method of the light output from the display unit 151 Can vary. Accordingly, the controller 180 controls the color or lighting method output from the display unit 151 according to the type of the event or the number of generated events, or controls the brightness or intensity of the color output from the display unit 151 Thereby allowing the user to control more specific information about the event.

As shown in FIGS. 12A and 12B, the control unit 180 controls the display unit so that the colors of the notification lights output at the boundaries of the window units are different according to the type of the generated event. can do. That is, the control unit 180 may control the display unit 151 to output the notification light in a unique color for each event. For example, when the first type of event (e.g., a message reception event) occurs as shown in (a) of FIG. 12A, When a second type event (for example, a missed call reception event) that is different from the first type is generated as shown in (b) of FIG. 12, , And a second color (e.g., red) different from the first color may be formed on the display unit 151. On the other hand, the inherent color for each event can be determined based on the user's selection. For example, in the present invention, the user can be given a selection as to which color of notification light is to be formed for an event. Therefore, although not shown, in the present invention, a setting screen for selecting a unique color for each event can be provided. Through this, the user can easily recognize what event has occurred by only the color of the notification light.

In addition, according to the present invention, even if the contents of the generated event are not displayed, information on the generated event can be provided to a user who recognizes a unique color according to the event. Therefore, the user can keep privacy by receiving event information through a color recognized only by the user, without exposing the information of the event currently generated to the third party.

As another example, in the mobile terminal according to the present invention, the lighting method of the light output from the display unit 151 can be controlled so that the lighting method of the notification light formed at the boundary of the window unit is changed according to the type of the generated event have. 12, an image is sequentially formed on the display unit 151 along the outer periphery of the window unit 240, and the image is displayed on the display unit 151 The control unit 180 may provide information on an event by using an image sequentially illuminated by the control unit 180. For example, the control unit 180 may generate a first type event (e.g., a message (A) and (b) of FIG. 12B, the display unit 151 is controlled so that the notification light is sequentially formed in the first direction with reference to the virtual reference axis a The control unit 180 can cause the light to sequentially light up. [0154] In addition, as shown in (c) and (d) The first reference axis (a) The user can sequentially turn on the light on the display unit 151 so that the notification light is sequentially formed (or emitted) in the second direction different from the direction of the notification light. The control unit 180 controls the display unit 151 so that the notification light is formed in the boundary region of the window when the first type of event (for example, a message reception event) The display unit 151 is turned on so as to form a notification light notifying the occurrence of the second kind of event in an area inside the notification light output to the border area when the second kind of event is generated, As described above, the notification light can be formed in the inner area sequentially from the outermost area of the window part.

On the other hand, as described above with reference to FIG. 12A, it is also possible to select from which direction the notification light will be sequentially formed in accordance with the type of event. Furthermore, although not shown, according to the present invention, not only the direction in which the notification light is formed but also the starting point of the notification light start may be different from each other. Thus, the point in time when the notification light starts to be illuminated can be selected by the user.

As another example, in the mobile terminal according to the present invention, more specific information about an event can be controlled to the user by controlling the speed at which the notification light is turned on for each event to be different from each other. More specifically, when the generated event is an event of the first type (for example, an event related to the first application), the control unit 180 determines whether the notification light is lit (E.g., a lighting rate at which an image for forming light is displayed) at a first rate, and when the generated event is a second type of event (e.g., an event related to the second application) different from the first type of event , It is possible to control the speed at which the notification light is lit (for example, the lighting speed at which the image for forming the notification light is displayed on the display unit) at a second speed different from the first speed.

In the above examples, the method of changing the color of the notification light, the lighting direction, and the lighting speed according to the type of the event has been independently described. However, in the present invention, at least two of the above examples may be implemented in combination. In other words, the color of the notification light differs depending on the type of the event and may be different from the lighting direction.

Meanwhile, in the mobile terminal according to the present invention, when a plurality of events are received for the same kind of event (for example, when a plurality of messages are received in a message reception event), the strength So that more specific information on the event can be provided. For example, as shown in FIG. 12C, when one message is received, the control unit 180 outputs the first dark light on the display unit 151, and two messages If received, the controller 180 may output the second darker light, which is darker than the first darker light, on the display unit 151. [ As a result, different notifications of the notification light 310 are formed in the border region of the window unit 240. The controller 180 controls the amount of current flowing in the display unit 151 to vary the brightness of the output light.

In addition, when the generated event is related to the state of the mobile terminal, based on the state of the mobile terminal (e.g., the generated event: the battery charging and related event, the state of the mobile terminal: (Or brightness) of the display unit 151 may be different from each other.

12A, 12B, and 12C illustrate examples in which the notification light is output. However, the present invention is not limited to the above description, It is possible to output event information together.

 Alternatively, the event information may be output after the notification light is output, based on a predetermined type of touch that is applied to one area 151 'of the display unit while the output of the notification light is maintained . In addition, the event information may be output based on a predetermined type of touch that is applied to one area 151 'of the display unit after the output of the notification light ends. That is, the event information can be output at various time points.

Hereinafter, a method of informing a user more effectively by using the notification light that there are a plurality of events of different kinds of unidentified events at the time when the notification light is displayed, will be described with reference to the accompanying drawings We will look at it in detail. 13A, 13B, 14A, 14B, 14C, and 14D are conceptual diagrams for explaining a method of notifying a plurality of events in a mobile terminal according to the present invention. In the following examples, the pattern generating mechanism for outputting the notification light follows the description of FIGS. 10, 11A, 11B, 12A, 12B and 12C.

In the present invention, when there are a plurality of notification target events to be guided through the notification light, the notification light is output in a plurality of colors, thereby informing the user that there are a plurality of notification target events. Here, the notification target event may occur before the time when the notification light is output corresponding to the currently generated event and the currently generated event, and may mean an unidentified event. That is, the notification target event means an unidentified event. As described above, when there are a plurality of notification target events, the control unit 180 can divide the outer periphery of the window unit 240 into a plurality of areas based on the number of the plurality of events. The control unit 180 may control the display unit to output notification lights of different colors around the divided areas.

For example, as shown in FIG. 13A, when there are two notification target events, the control unit 180 displays two notification target events in two different colors The display unit 151 can be controlled so that the notification lights 310a and 310b are formed. At this time, images corresponding to two colors are output to the display unit 151, and notification lights corresponding to the images can be formed in the border area of the window unit 240. [

On the other hand, in a state in which the notification lights 310a and 310b are formed in two different colors, a touch starting from one point of one area 151 'of the display unit corresponding to the window unit 240 is divided into two Event information of an event corresponding to one of the notification lights may be output when the user drags (or slides) the color of the notification light 310a or 310b toward the side where the notification light 310a or 310b is formed. Here, one point at which the drag (or slide) touch is started may be a central portion of one area 151 'of the display unit.

13A, if there are four notification target events, the control unit 180 determines that there are four notification target events, for example, The display unit 151 can be controlled so that the notification lights 310a, 310b, 310c and 310d are formed in a color. At this time, images corresponding to four colors are output to the display unit 151. [

Here, the different colors are determined based on the types of the plurality of events, and information on the different colors may be stored in the memory in association with information of applications corresponding to the plurality of events, have.

That is, the control unit 180 may control the display unit 151 to output the notification light in a unique color for each event. The inherent color of each event can be determined based on the user's selection. For example, in the present invention, the user can be given a selection as to which color of notification light is to be formed for an event. Therefore, although not shown, in the present invention, a setting screen for selecting a unique color for each event can be provided. Through this, the user can easily recognize what event has occurred by only the color of the notification light.

As described above, in the present invention, when there are a plurality of notification target events, the notification light can be formed in a plurality of colors corresponding to the number of notification target events in order to inform the user more effectively. Therefore, the user can grasp at a glance how many events have occurred and the specific color corresponding to the event, based on the number of colors of the notification light.

Meanwhile, in the mobile terminal according to the present invention, in addition to the method of outputting the graphic image for forming the notification light on the display unit 151, as shown in (c) and (d) A graphic object can additionally be output in an area corresponding to the output area. More specifically, as shown in FIG. 13 (c), the control unit 180 can output graphic objects output in the same color as the notification light to one area 151 'of the display unit. Further, the controller 180 may equally divide one area 151 'of the display unit into an area corresponding to the number of generated events, and output a graphic image having the same color as the notification light formed in the adjacent area have.

In this case, when the central portion of the area is selected, the controller 180 may display event information at a time by outputting all of the generated plurality of events. In addition, when the respective areas are individually selected, the controller 180 can output only the event information corresponding to the selected individual area to one area 151 'of the display unit.

As another example, in the present invention, when there are a plurality of notification target events, the notification light corresponding to the unique color of each event can be sequentially output. For example, when there are two notification target events corresponding to the first kind and the second kind of event, the control unit 180 responds to the first kind of event (for example, an event related to the first application) The second display unit 151 controls the display unit 151 to form the notification light of the first color corresponding to the second kind of event (for example, the event related to the second application) So that the display unit 151 can be controlled. That is, the control unit 180 may control the display unit 151 to sequentially form the notification lights corresponding to the first and second colors. Further, after the output retention time of the notification light corresponding to the second color has elapsed, the control unit 180 may form the notification light corresponding to the first color again as shown in FIG. 13B (c) . 13B, when the event of the third kind exists, the controller 180 displays the notification light of the third color corresponding to the event of the third kind, The control unit 151 can be controlled. 13A and 13B, there is shown an example in which event information is output together with FIG. 11A and FIG. 13B. However, in the case of FIGS. 13A and 13B, May be output to one area 151 'of the display unit.

Hereinafter, a method of outputting event information in the example shown in FIG. 13A will be described in more detail.

As described above, in the present invention, when an event is generated, the display unit can be controlled so that the notification light based on the color information associated with the generated event is output. Furthermore, the control unit 180 may output event information (for example, application information, status information, and the like) corresponding to the event generated in one area 151 'of the display unit together with the notification light.

For example, as shown in FIGS. 14A and 14B, in a state in which the notification light having a plurality of colors is output from the outer periphery of the window portion 240, Icons 311, 312, 313, and 314 representative of the event corresponding to the notification light may be output on the exposed region 151 'exposed through the window portion to correspond to the position where the notification light is formed. Here, the icons 311, 312, 313, and 314 may be arranged along the outer circumference of the window portion.

In particular, if a predetermined type of touch is applied to the window unit within a predetermined time after the notification light having a plurality of colors is output from the outer periphery of the window unit 240, It is possible to output a plurality of icons 311, 312, 313, and 314 each representing a corresponding application.

Further, when a plurality of icons are output, the controller 180 determines whether any one of the icons is displayed (see (b) of FIG. 14) The detailed information of the event corresponding to the selected icon can be displayed on the exposed area 151 '.

Further, in the present invention, when any one of the plurality of icons is selected to provide information on which event the present detailed information is outputted, the notification light having a plurality of colors along the outer circumference of the window portion is selected It is possible to switch to a color associated with an event (or application) corresponding to the icon.

On the other hand, if detailed information on one event is output through selection of the icon among the plurality of notification target events, the event in which the detailed information is output is regarded as confirmed. Therefore, as shown in FIG. 14 (c), the output of the icon corresponding to the event in which the detailed information is outputted is ended in the exposure area 151 ' The notification light is no longer formed. That is, the control unit 180 may control the display unit 151 so that the notification light corresponding to the event in which the detailed information is output is not formed.

That is, since the different colors forming the notification light each represent the plurality of notification target events, the controller 180 controls the color corresponding to the confirmed event among the plurality of notification target events to be different from each other It can be excluded from color.

As shown in Fig. 14C, when the detailed information on any one of the plurality of notification target events is output, (C) of FIG. 14C, when the touch of the predetermined type (for example, flicking, slicing, dragging touch, etc.) is again applied to the window portion, (Or the exposure area 151 ') to detailed information about the other one of the plurality of notification target events. In addition, when the detailed information output for the notification target event is completed, basic information (or default information) can be displayed on the exposed area 151 'of the display unit, as shown in (d) of FIG.

Meanwhile, in the present invention, icons displayed together with the above-mentioned notification light can be displayed in colors associated with applications (or types of events) corresponding to a plurality of icons, as shown in FIG. 14D. That is, the controller 180 may output images corresponding to the colors associated with the respective icons on the periphery of the icons, or may display the icons themselves in the associated color tones.

The description above shows a method of forming a notification light notifying of occurrence of an event in a mobile terminal covered with a cover which is guided by the guide sheet 251 and forms the notification light 310 at the boundary of the window portion 240 .

In the present invention, in addition to the method in which the light output from the display unit 151 is guided by the guide sheet 251 to form the notification light, the light output from the display unit 151 is reflected by the guide sheet 251 It is possible to control the display unit 151 to be formed as a notification light without being guided. The pattern generation mechanism for forming the light output from the display unit 151 as a notification light may be implemented by the structure of the cover according to FIG. 5 or by controlling the display unit 151. FIG.

10, 11A, 11B, 12A, 12B, 12C, 13A, 13B, 14A, 14B, 14A, 14B, , Fig. 14C and Fig. 14D, a detailed description thereof will be omitted.

Also, in the mobile terminal according to the present invention, a circular graphic image is output along the outer periphery of the window part 240 among the exposed area 240a formed by the window part 240, so that the notification light can be formed. That is, in this case, the output of the graphic image can replace the role of the notification light. For example, as shown in FIGS. 15A and 15B, the control unit 180 may output a graphic image corresponding to a specific color in a boundary region of the window unit 240.

More specifically, referring to the accompanying drawings, as shown in FIG. 15A, when an event occurs in the mobile terminal, when the display unit 151 is covered by the cover 200, A graphic image 410 (or notification light) corresponding to a specific color is output in an area corresponding to a boundary part of the window part 240 among the negative exposure areas 151 '. That is, when an event occurs in the mobile terminal, the control unit 180 detects that the cover unit 200 covers the display unit 151, and the graphic image 410 is output at the boundary of the window unit 240 At least one area of the display unit 151 is activated. Accordingly, the user can recognize that an event has occurred on the mobile terminal through the graphic image 410, even if the display unit 151 is covered by the cover 200. [

In the mobile terminal according to the present invention, when an event occurs in the mobile terminal while the display unit 151 is covered with the cover 200, as shown in FIG. 15A, In conjunction with the graphic image 410 in the exposure area 151 ', as shown in Figure 15 (b), in addition to the method of causing the graphic image 410 to be viewed at the border of the window part 240, Event information can be output. Here, the event information may be brief information including at least one of the name of the event-generated application and the graphic image representing the application, detailed information including the content of the generated event, and the like. Such event information can be output from the exposure area 151 'at the same time that the graphic image 410 is output. Alternatively, the event information may be displayed on the basis of a touch of a preset method applied to the exposure area 151 'while the output of the graphic image 410 is maintained after the graphic image 410 is output , ≪ / RTI > In addition, the event information may be output based on a predetermined type of touch applied to the exposure area 151 'after the output of the graphic image is terminated. That is, the event information can be output at various time points. In the present invention, while the event information is displayed, the display unit 151 may be controlled to output the graphic image 410 together, or the event information, the display, and the output of the graphic image 410 may be independently controlled . On the other hand, the notification light 310 may be displayed only for a predetermined time, and then the output may be terminated. Also, if the generated notification event is not acknowledged, the notification light 310 is displayed at the reference time interval, and then the output is ended after the display is performed for the predetermined time, or the output is continuously maintained until the event is confirmed .

Also, although not shown, when event information corresponding to simple information is displayed in the exposed area 151 'of the display unit, an event corresponding to the detailed information is displayed on the basis of the touch of the exposed area 151' More information can be output.

15 (a), when a touch is applied to one area 151a of the display unit in a state in which the notification light 410 is output, the mobile terminal of FIG. 15 (b), brief information or detailed information about the generated event can be output.

When the display unit 151 is shielded by the cover 200, the memory 170 may display the notification light 410 in the boundary area of the window unit 240 among the display areas of the display unit 151, Or a graphic image) is output, information about an area to which a graphic image is to be output may be stored in advance. The information on the exposure area may be information on the position where the window part 240 or the like is arranged in the cover 200. Accordingly, when an event occurs in the mobile terminal while the display unit 151 is covered by the cover 200 based on the information on the exposure area, the controller 180 controls the display unit 151 on the outer circumference of the window unit 240 By outputting the graphic image to the corresponding area, information on the event can be provided.

As shown in FIG. 15, even when a graphic image corresponding to the notification light is output in the boundary region of the window unit 240, 13A, 14B, 14C and 14D, the control method of outputting the notification light and the icon according to the kind and the number of the events can be similarly applied. Therefore, 11a, 11b, 12a, 12b, 12c, 13a, 13b, 14a, 14b, 14c and 14d.

16A and 16B are conceptual diagrams for explaining a method of notifying occurrence of an event by utilizing another area of the cover in the mobile terminal according to the present invention.

Referring to these drawings, when an event occurs in the terminal, the notification light 510 is output from the border area 480 (see FIG. 7) of the cover 200.

The control method described with reference to Fig. 10 can also be applied to the case in which the notification light is output in the border area as in this example. For example, when an event occurs in the mobile terminal according to the present invention, the control unit 180 detects whether the display unit is blocked by the cover. When an event occurs in the mobile terminal, when the display unit is covered with the cover, the notification light indicating that the event has occurred is output to the edge region 480 of the cover provided in the cover.

7, the warning light is a guide sheet (diffusion sheet) or the like, which is included in the guide unit 450 and diffuses the light incident on a part of the surface, Diffusion film).

In the present invention in which the pattern generating mechanism is combined with the cover having the structure as described above, when an event occurs in a state that the display unit 151 is covered with the cover 200, an area covered by the cover 200 The display unit 151 is activated to light up. The light output from the display unit 151 is incident on the guide unit, and the incident light is diffused into the rim area 480 and externally emitted. That is, the light emitted to the outside becomes annular light in the edge area 480 in this manner. Accordingly, the user can recognize that an event has occurred on the mobile terminal through the notification light 510 even if the display unit 151 is covered with the cover 200. [

In addition, although not shown, when there are a plurality of events, the controller 180 controls the display unit 480 to emit light, which is diffused into the border area 480, in a plurality of colors corresponding to the number of events 151 can be controlled. That is, the edge region 480 is divided into a plurality of regions, and light representing each of different events in each region may be emitted. That is, the outer region of the display unit 151 may be divided into a plurality of regions, and images of different colors may be output.

Event information on an event generated when the cover 200 is covered can be output on the display unit 151 when the display unit 151 is exposed to the outside, that is, when the cover 200 is opened have. The control unit 180 may output the summary information of the generated events in a list format or an icon or a widget format. The event information may be output on a home screen page or a lock screen. Further, the event information may be output in a pop-up window format on the home screen page or the lock screen.

Meanwhile, in the mobile terminal according to the present invention, when an event occurs in the mobile terminal in a state that the display unit 151 is covered by the cover 200, as shown in FIG. 16B (a) May be displayed in the border area 480 and the event information related to the generated event may be output through the exposed area 151 'of the display unit exposed to the outside by the window unit 240. [ Here, the event information may be brief information including at least one of the name of the event-generated application and the graphic image representing the application, detailed information including the content of the generated event, and the like. The event information can be output from the exposure area 151 'of the display unit at the same time that the notification light 510 is output. Alternatively, the event information may be output based on a predetermined type of touch that is applied to the exposed area 151 'of the display unit in a state where the output of the notification light is maintained after the notification light is output . In addition, the event information may be output based on a predetermined type of touch that is applied to the exposed area 151 'of the display unit after the output of the notification light ends. That is, the event information can be output at various time points.

In the present invention, while the event information is displayed, the display unit 151 can be controlled to output the notification light 510 together, or the output of the event information, the display, and the notification light 510 can be independently controlled . On the other hand, the notification light 510 may be displayed only for a predetermined time, and then the output may be terminated. Also, if the generated notification event is not confirmed, the notification light 510 is displayed at the reference time interval. After the notification light 510 is displayed for the preset time, the output is terminated or the output is continuously maintained until the event is confirmed .

As another example, the notification light 310 may be displayed in the boundary area of the window part 240 in addition to the method in which the notification light 510 is displayed in the border area 480, as shown in FIG. 16B (b) And notify that an event has occurred.

More specifically, when an event occurs, the notification light 510 of the border area 480 and the notification light 310 of the border area can be simultaneously output. In this case, the terminal and the cover may have at least one of the mechanisms described in Figs. 3 to 6 and the mechanism described in Figs. 7 and 8 together.

As another example, when an event occurs, the notification light 510 in the border area 480 and the notification light 310 in the border area can be sequentially output. More specifically, when a first type of event (e.g., a message reception event) occurs, the display unit 400 displays the notification light 510 in the border area 480 and the notification light 310 in the border area, The notification light 510 of the border area 480 and the notification area 510 of the border area 480 are generated when a second type of event (for example, a missed call reception event) It is possible to control the display unit 151 so that the other one of the notification lights 310 of the display unit 151 is formed. It is also possible that the notification lights 310 and 510 are sequentially output even when the number of events is the same for each event.

FIGS. 17A, 17B, 17C, and 17D are conceptual diagrams for explaining a method of controlling a mobile terminal using a touch on a cover. FIG.

The cover 200 includes a window unit 240 for exposing time information of the display unit 151 to the outside and a touch sensing unit 590 for sensing a touch input of the user. 17A, 17B, 17C, and 17D, when an event occurs in a state in which the display unit is inactivated, the notification light 310 may be output at the boundary of the window unit, but these examples are not necessarily limited thereto . For example, the terminal control related to the touch to the cover can be performed regardless of the notification light output.

Referring to FIG. 17A, if there is a touch input to the touch sensing unit 590, the terminal responds and drives an application related to an event occurring in the terminal. In addition, the details of the event may be output to the window unit 240 together with the application.

For example, as shown in FIG. 17A, the controller 180 controls the display unit 151 to form a notification light when a specific event (for example, a message reception event) occurs, It is possible to output an icon representative of the event in the exposure area 151 '. In this state, when a touch input such as a short touch, a long touch, a drag, or a flicking is applied to the touch sensing unit 590, the terminal senses the touch input. In this way, the cover 200 is operated so that the user can operate the display unit 151 while covering the display unit 151 of the terminal.

In this example, when a drag input is applied to the touch sensing unit 590, the terminal senses it and drives an application (for example, a message application) related to the specific event. At this time, the input of the control command of the user to the application may be restricted in other parts except for the touch sensing part 590. This is for preventing the application from being activated by inputting a control command that is not intended by a user, mainly in a terminal capable of touch input.

In addition, as shown in FIG. 17A, the control unit 180 drives an application related to the specific event, and an execution screen of the application is output to the exposure area 151 '. In this case, the contents of the received message may be displayed on the execution screen. That is, when the application is activated, the content of the received message is output to the exposure area. Also, when the contents of the message are output, the display unit 151 can be controlled so that the notification light disappears.

Referring to FIG. 17B, if there is a touch input to the touch sensing unit 590, the terminal controls a specific operation of an application currently being executed. For example, when a specific application is operated in the terminal and the cover 200 covers the display unit 151 of the terminal, an execution screen related to the application is output to the exposure area 151 '. In this state, the terminal receives the control command related to the operation of the application through the touch input to the touch sensing unit 590, and performs the control command.

17B, when the audio reproducing application is driven and the audio is reproduced (or when the reproducing is completed), the control unit 180 sets the exposure area 151 ' And outputs key (s) (audio reproduction control key) for controlling audio reproduction. In this case, even if there is a touch input to the window unit 240, the terminal does not process the touch input, and if there is a touch input to the touch sensing unit 590, it processes the control command related to audio reproduction. In addition, the control unit 180 may further store the representative image of the audio data (for example, a thumbnail image of the music file), audio data information (e.g., music title, artist name, It can also be displayed.

As an example of this, a position corresponding to a key (e.g., a playback key PLAY, a stop key STOP, a fast forward key FF, a backward key FR, etc.) When a touch (e.g., a short touch) is applied to a position corresponding to a lower portion of the touch panel (not shown)).

As another example, referring to (b) of FIG. 17B, when a drag input is applied to the touch sensing unit 590, the volume of the audio reproduction may be adjusted. In this case, when the drag input is sensed, the controller 180 may output an indicator indicating the degree of the volume control in the exposure area. In addition, the control unit may control the display unit 151 so that the notification light 310 blinks together with the volume control, thereby providing feedback to the user on the volume control.

Referring to FIG. 17C, if there is a touch input to the touch sensing unit 590, the terminal senses the touch input and controls the camera of the terminal in response to the touch input.

The control method starts by displaying the image input through the camera 121a or 121b on the display unit 151 when the camera 121 enters the camera mode in which the camera 121a or 121b, Lt; / RTI > At this time, if the cover is covered with the terminal, the image sensed by the camera is reduced to a size corresponding to the exposure area 151 'as a preview image and output to the exposure area 151'.

According to the illustrated embodiment, an indicator related to the current state of the sensed image may be output to the exposed region 151 '. The indicator may be, for example, a focus icon, a zoom icon, a brightness adjustment icon, a menu selection icon, or the like. In this case, if there is a touch input to the touch sensing unit 590, the terminal uses the touch input to change the position, the state, and the like of the icon.

17C, a focus icon is displayed together with the image sensed by the camera in the exposure area 151 ', and the touch sensing unit 590 displays the focus icon as shown in FIG. 17C (b) The position of the focus icon is shifted in response to the touch input. At this time, the camera 121a or 121b may be controlled so that the subject to be focused is changed in accordance with the movement of the focus icon. As another example of continuously moving a touch point such as a drag to the touch sensing unit 590, when a drag input is sensed in the touch sensing unit 590 while the camera is activated, the controller 180 ) Can process the drag input as an instruction to zoom or out of the camera.

As another example, before the zoom function is activated, the control unit 180 changes the focus of the camera in response to the drag touch with the touch sensing unit 590 and zooms in the drag input after the zoom function is activated In and zoom-out command. In this case, the zoom-adjusted image may be captured and stored when the drag is completed (or when the user releases the touch sensing unit).

Meanwhile, although not shown, the cover unit corresponding to the touch sensing unit 590 may be formed in a translucent manner to transmit screen information output to the display unit 151. That is, the user can recognize the screen information output to the display unit 151 through the semi-transparent cover unit. At this time, a control button for controlling a function currently being performed in the mobile terminal may be output to the display 151. [

For example, when the camera is activated, the control unit 180 displays a photographing function icon, a video switching function icon, a stop function icon, and the like on the display area of the display unit 151 corresponding to the touch sensing unit 590 When the touch input is applied, the position of the focus icon moves along the direction of the movement. In this state, when another touch input, for example, a short touch, a tap, or the like is applied to the touch sensing unit 590, the photographing is performed. As another example, when the drag is released, the photographing may be performed based on the subject on which the focus icon is located at the time of releasing the drag.

17D, if there is a touch input to the touch sensing unit 590 with the cover covering the display unit, the terminal processes the touch input as a control command for a predetermined application.

In this case, if there is a touch input to the touch sensing unit 590 in a state that the display unit is covered, one area 151 'of the display unit may be activated to output screen information related to the currently applied touch input .

In this embodiment, the terminal is made capable of executing the remote control application, and when the remote control application is executed, the execution screen of the remote control application may be output from the terminal.

 The touch input to the touch sensing unit 590 is defined as the operation of the remote control application or the control of the specific operation without outputting the execution screen of the remote control application. For example, when a short touch or a tap is applied to the touch sensing unit 590, the terminal senses the touch and transmits a driving signal (for example, a power signal) to an image display device do. In the exposure area 151 ', notification information indicating that the driving signal is transmitted may be output. In this case, the remote control application can be executed in the terminal together with the transmission of the driving signal. When the remote control application is executed, an associated execution screen may be output to the exposure area 151 '.

As another example, if a touch input is applied to the touch sensing unit 590 in the event that an event occurs in the terminal, the touch input is processed by inputting a control command related to a second application different from the first application processing the event . That is, the touch input to the touch sensing unit 590 may be defined as a specific function irrespective of the output of the notification light 310. As a more specific example, when a touch input is applied to the touch sensing unit 590 in a state that a message is received and the notification light 310 is being output, the touch input is transmitted to the first application 2 application (remote control application).

The control unit 180 may control the display unit 151 to change the notification light 310 into notification light of a different color or blink the notification light together with the control command related to the second application, Feedback to the processing of the command can be provided to the user.

The present invention also provides another method of providing feedback to a user. 18 is a conceptual diagram for explaining a method of providing feedback to a user when a cover is covered on a mobile terminal according to the present invention.

Referring to these drawings, the terminal may be configured to detect a touch input applied to a window portion of a cover. In this case, the terminal may be configured to detect a change in the amount of charge at a position corresponding to the window portion with the cover covering the terminal, or to sense the pressure applied to the cover.

The feedback provided to the user may be implemented as the notification light is changed according to the touch input. 18 (a), basic information (or default information) is displayed on the exposed area 151 'of the display unit. When an event occurs in this state, the notification light 310 Is output.

In this case, when the touch input is applied to the window unit 240, the terminal senses the touch input and releases the notification light 310. At this time, if there is another event, the terminal does not release the output of the notification light 310 but outputs the notification light as, for example, a dark color (see (b) in FIG. 18) Or shorten it. Through this, the user can know that another event exists, and receives feedback that the preceding event has been confirmed.

The control method may be repeated if an unidentified event is present. For example, when a touch input is applied to the window unit 240 in the state of FIG. 18 (b), if there is another event, the control unit displays the notification light in a darker color as shown in FIG. 18 (c) Can be output.

In addition, the sequential change of the notification light in the above-described control method can provide a new type of setting method to the user. For example, when an event occurs, the color of the notification light output may be set by a touch input to the window unit 240. For example, when the touch input is sequentially applied to the window unit 240, the colors of the notification light sequentially change, and when the notification light of any color is being output, (For example, long touch) is applied, the color of the notification light currently being output can be set as the color of the notification light that is output when the event occurs.

19A, 19B, 19C, 19D, 19E and 19F illustrate a method of providing a corresponding user interface when a cover having a circular window is covered on the mobile terminal according to the present invention Fig.

Referring to these drawings, information (for example, a first type of graphic user interface) that is output to the display unit in a state that the front surface of the terminal is opened by the cover 200, Information (e.g., a second type of graphical user interface). For example, the information output in the open state may be output at a position outside the circular window in the display unit, and the information output in the case of covering may be limited to the area corresponding to the circular window in the display unit.

For example, when the cover is opened and the home screen page is displayed on the display unit or when the cover is covered with the execution screen of a specific application being output, other information may be output in the exposure area 151 'of the display unit.

Here, the home screen page may be referred to as an idle screen, and the home screen page may be output on the display unit when the terminal is in a standby state. More specifically, an icon of an application installed on the mobile terminal, a folder where the icons are stored, or an icon of a widget may be displayed on the home screen page.

In addition, if the cover is covered, the information output in the exposed area 151 'of the display unit can be a lock screen. The lock screen may be a screen capable of only touch input related to the operation of releasing the lock state. The lock screen may be output when an event occurs in the terminal when the display unit is inactivated.

As a more specific example, referring to FIG. 19A, an image of an analog clock may be output to a circular window, that is, the exposure area 151 'when the cover 200 is covered. In addition, when the cover 200 is open, a digital clock or analog clock of a different size is output, and if the cover is covered, the analog clock can be output in the exposure area 151 '.

In addition, a status display window 610 may be displayed at the top of the image of the analog clock. The status display window 610 may be displayed or not displayed in some cases, and is displayed at the top of the window when displayed.

On the other hand, the state display window 610 may be changed in the area where the status display window 610 is output based on the drag or slide touch of the area where the status display window 610 is output. When the state display window 610 covers one area 151 'of the display unit over a certain range, a GUI screen as shown in FIG. 19 (b) may be output to the state display window 610.

In addition, when an event occurs in the terminal, the notification light 310 can be output from the border area of the window unit 240. [ That is, when an event occurs in the terminal, the image of the analog clock is output to the exposure area 151 ', and the notification light 310 is output in the boundary area of the window part 240. However, the present embodiment is not limited to the output of the notification light 310, for example, the output of the notification light 310 may be omitted.

19A, when a touch is applied to the window unit 240, the window unit is unlocked and the icon of the application installed in the mobile terminal or the icon of the widget Icon or the like may be displayed. However, the present invention is not necessarily limited to this. When an event occurs, the window is unlocked without a control operation related to (a) of FIG. 19A and the icon of the application installed in the mobile terminal or the widget an icon of a wiget can be displayed.

In this case, an icon of an application or widget in which an event has occurred may be output to the window unit 240. As another example, the icons may be arranged in the window unit 240 according to a rule set as a default.

In addition, the icons may be a part of the icons displayed on the home screen page. In this case, when the cover is opened, the icons may be arranged in a matrix form and then arranged in a circle along the periphery of the window portion 240 when the cover is covered.

On the other hand, when icons are dragged or slid into a predetermined area (for example, one area 151 'of the display unit) in a state where the icons are arranged as shown in FIG. 19A, The controller 180 may accept such a touch as a selection for the dragged or slidted icon. Accordingly, the control unit 180 may display event information of an application corresponding to the dragged or slidted icon, or may execute an application corresponding to the dragged or slidted icon.

Referring to FIG. 19B, when the cover is covered, the icons 620 output to the window unit 240 may be gathered at one point and expanded by the user's input. If the icons are gathered at one point and expanded according to the user's selection, other information may be displayed in a limited area of the window unit 240. [ The other information may be either the information displayed in the previous example or the information displayed in the exposure area in another example described below.

More specifically, for example, as shown in FIG. 19B (a), a plurality of icons 620 are output in a superimposed manner to each other, and a first icon (not shown) receiving an input expanding the plurality of icons 620 Expanded command reception icon) is output. When the user touches the first icon through the window unit 240, the terminal senses the touch and displays a plurality of icons 620 superimposed on each other on the window unit 240 as shown in FIG. And spread out to be arranged in a circle along the outer periphery. In this case, a second icon (meeting command receiving icon) for receiving the input for collecting the plurality of icons 620 is output. As shown in FIGS. 19B and 19C, when the touch input is applied to the second icon, the icons 610 that have been expanded are gathered at one point and overlapped with each other.

However, the spreading and gathering of icons may be applied to the window portion in other forms. For example, referring to FIG. 19C, a plurality of icons 620 may be gathered or unfolded by a drag input.

More specifically, for example, as shown in FIG. 19C, a plurality of icons 620 are output in a superimposed manner to each other, and a user inputs a drag input A plurality of icons 620 overlapped with each other are spread in a circular shape along the outer periphery of the window part 240 as shown in FIG. As shown in (b) and (c) of FIG. 19c, when the dragged input is applied to the plurality of opened icons 620, the icons 610 which have been expanded are gathered at one point again and overlapped with each other.

Referring to FIG. 19D, when a touch input is applied to any one of the displayed icons, the number of events may be displayed. For example, as shown in (a) of FIG. 19 (d), when an event occurs, the notification light 310 is output to the border area of the window unit 240. At this time, an icon of an application installed in the mobile terminal or an icon of a widget may be displayed while the window 240 is unlocked. As another example, if a touch is applied to the window unit 240 after the notification light 310 is output, the window unit is unlocked and the icon of the application or the icon of the widget (wiget) (icon) or the like may be displayed.

In this case, when a user's touch input (e.g., short touch, long touch, drag, flicking, tab, etc.) is applied to any one of the outputted icons (refer to (a) The number of events occurring is displayed while being inverted (see Fig. 19 (b)). In this case, icons other than the icon to which the touch input is applied can continue to maintain the output format. Also, the output of the notification light 310 may be maintained until a command for confirming an event is inputted.

19B, when a touch is applied to the corresponding icon again in a state where the number of generated events is displayed, brief information or detailed information on the generated event is displayed on one area 151 'of the display unit Can be output. The simple information or the detailed information can be output in a list format.

Referring to FIG. 19E, the touch input applied to the window portion can be set as a control command for performing a specific function of the terminal. As an example of this, when the touch input is applied to the background in which the icons are output, the editing function of the background can be performed.

19E, when the cover covers the terminal, an icon of an application or an icon of a widget is displayed in the exposed area 151 ' Can be displayed. The icons may be arranged sequentially along the periphery of the window portion on the background.

Referring to FIG. 19 (b), when a touch input (for example, a short touch, a long touch, a drag, a flicking, a tap, etc.) is applied to the background, an edit Function is performed. For execution of the editing function, an execution screen of an application additional function may be displayed in the exposure area 151 '.

If a touch input (for example, a short touch, a long touch, a drag, a flicking, a tap, etc.) is applied to the background as shown in Figs. 19E and 19B, a basic background screen including clock information and the like may be output instead of the screen information corresponding to the editing function as shown in FIG. Here, the output screen that is basically set may be the basic background screen. If the touch input (for example, short touch, long touch, drag, flicking, tab, etc.) is applied to the basic background screen, A GUI screen as shown in FIG. 19 (a) can be output. Here, the basic background screen may be screen information as shown in FIG. 19A (a).

19A is an icon corresponding to an application in which an event has occurred, the controller 180 displays a touch corresponding to a preset method (for example, a long touch, a drag Touch, or the like) is added, the event can be processed as being confirmed.

In the case of the control process of FIG. 19E, when an event occurs before, during, or after the start of the process, the notification light may be output to the boundary region of the window unit 240. However, this example is not necessarily limited to this, and the notification light may not be output during the control process.

Referring to FIG. 19F, the terminal may be configured to select information to be output to the exposure region 151 'through touch input to the exposure region 151'.

For example, in a state in which a first type screen 710 (for example, a screen including an image) is outputted to the exposed region 151 'of the terminal, the cover 200 and the terminal They can be combined with each other to receive only input that changes the screen.

In this case, the output of the screen of the first form may be performed as an event occurs in the terminal. When an event occurs in the state that the exposed region 151 'is inactive, the notification light 310 is output in the boundary region of the window unit 240, and the first-type screen can be output together with the notification light 310 (a)).

When a touch input is applied to the window unit 240 in a state in which the screen of the first form is output as shown in (b) of FIG. 19 (f), the terminal inputs the touch input to the first- The control command is changed to the screen. For example, if the first type of screen 710 is touched by the touch input (e.g., short touch, long touch, drag, flicking, tap, etc.) A screen of the second type is output (see Fig. 19 (c)). In this case, the screen of the second type may be, for example, a screen in which an icon of an application or an icon of a widget is sequentially arranged along the outer circumference of the window portion.

20A, 20B, 21A, 21B, 21C, 21D and 21E illustrate a case where a cover having a circular window is covered with a mobile terminal according to the present invention, FIG. 7 is a conceptual diagram for explaining a method of providing a user interface that can be used.

20A and 20B, when the terminal is covered by the cover 200, the terminal processes the touch input applied to a specific portion of the window unit 240 as a control command for performing a specific function can do. In addition, in these examples, the information that is output to the display unit in the state that the front surface of the terminal is opened by the cover 200 may be accompanied by switching to other information when the cover 200 is covered.

Referring to FIG. 20A, when the terminal is covered by the cover 200, an execution screen of a currently executed application (a reproduction application in this example, a gallery application as another example) is displayed in the exposure area. In addition, notification light 310 may be output in the border area of the window unit 240 according to the occurrence of an event. In addition, an indicator 810 may be provided inside the boundary area to indicate that the window 810 is an area for performing a specific function (volume adjustment in this example, brightness adjustment as another example) along the outer periphery of the window part 240.

The indicator 810 may be implemented in various forms as shown in FIGS. 20A and 20B. The indicator 810 may include touch inputs (for example, a short touch, a long touch, a drag, a flicking, Etc.). For example, when a plurality of images are arranged along the outer periphery of the window unit 240 as shown in FIG. 20A, when a short touch is applied to any one of the plurality of images, the volume is adjusted Brightness adjustment). As another example, if dragging is applied to an image formed along the outer periphery as shown in (b) of FIG. 20A, the volume (or brightness) may be adjusted to a size corresponding to the length of the drag.

In the control process of this example, when an event occurs before, during, or after the start of the process, the notification light 310 may be output to the border area of the window unit 240. [ However, this example is not necessarily limited to this, and the notification light may not be output during the control process.

Referring to FIG. 20B, when the terminal 200 is covered by the cover 200, the execution screen 910 of the audio playback application currently being executed is displayed in the exposure area 151 '. An image, a playback icon, and the like may be output to the execution screen 910. In this case, if a touch input is applied to the window unit 240, the touch input is processed as a control command that performs a specific function of the audio reproduction application.

For example, if a drag input is applied to the execution screen 910 as shown in FIG. 20B, the execution screen 910 may be reduced and a border image 920 wrapping the execution screen may be output . The reduced execution screen 910 and the border image 920 are combined with each other to form an image like a turntable.

At this time, the drag input may be applied to an area where the border image 920 is output. Depending on the direction of the drag input, fast forward (FF) and backward (FR) may be performed on the reproduced audio. That is, the backward winding is performed when the drag input is applied in the direction of winding the turntable, and the forward winding is performed when the drag input is applied in the reverse direction. As a result, an input of a form in which the turntable is wound or unwound can be applied.

FIGS. 21A to 21E illustrate a method of providing a user interface in which a specific image is changed in location or shape along the circumference of a circular window portion 240. FIG.

Referring to FIG. 21A, when the cover 200 is covered, an image of an analog clock can be output to the circular window portion 240, that is, the exposed region 151 '. In addition, when the cover 200 is open, a digital clock or analog clock of a different size is output, and if the cover is covered, the analog clock can be output in the exposure area 151 '.

In addition, the clock hands (hour hand or minute hand) of the analog clock can be rotated by the user's drag input. For example, when a first touch input (for example, a tap or a long touch) is applied to the window unit 240 while an image of an analog clock is output, an adjustment mode for adjusting the hour hand or the minute hand of the analog clock . In the adjustment mode, the notification light 310 may be output to the boundary region of the window unit 240. In this case, the notification light 310 performs a function of notifying that the control mode has been executed.

In addition, when the control mode is executed, the control unit 180 can notify that the control mode has been executed by using at least one of vibration and sound in addition to the notification light 310. [ That is, the user can be provided feedback via the notification information output through at least one of the notification light, the vibration, and the sound that the control mode has been executed.

In the adjustment mode, when the user applies a second touch input (e.g., a drag) to the hour hand or the minute hand, the hour hand or minute hand rotates by the second touch input. Thereafter, when the first touch input (for example, tap or long touch) is applied again, the adjustment mode can be ended. In response to the second touch input, at least one of the notification light, the vibration, and the sound may be output to provide feedback indicating that the second touch input is being effectively received.

As another example, referring to FIGS. 21B to 21D, when the cover 200 is covered, a dial image of the analog telephone can be output to the circular window portion 240, that is, the exposed region 151 '. In this case, when the cover 200 is open, the dial image is not output, and when the cover is covered, the dial image can be output in the exposure area 151 '.

When the user applies a touch input moving along the outer periphery of the circular window portion 240 to the dial image, the dial image rotates in response to the touch input. At this time, the inputted number can be set according to the degree of rotation. For example, when dragging is performed along the outer periphery of the window portion 240 to the end of rotation after touching any number ('8' in this example) (see FIG. 21B) (See Fig. 21B (b)). In this case, an indicator indicating the end point of the rotation may be output to the dial image, and the inputted number may be displayed inside the dial image. In this case, if the inputted number corresponds to the number of the counterpart terminal, a call signal connection to the counterpart terminal can be performed.

As another example, when a touch input (for example, a short touch, a long touch, a tap, or the like) is applied to the numbers listed in the dial image, an input for the corresponding number can be performed. Also in this case, the input number is displayed inside the dial image, and if the inputted number corresponds to the number of the counterpart terminal, a call signal connection to the counterpart terminal can be performed.

As another example, as shown in Fig. 21D, the numbers listed in the dial image may be designated as abbreviated numbers. The abbreviated number is a number that can be called by shortening the other party's telephone number, and is set by the user. More specifically, the telephone number of one of the other party is assigned to any one of the numbers listed in the dial image, and when the user inputs a touch input (e.g., a short touch, a long touch , Tap, etc.), the call signal connection can be performed to the designated telephone number.

However, this example is not limited to the abbreviated number, and the favorite function may be performed. As a specific example, a specific application or a specific web page is assigned to the number, and when a touch input is applied to a certain number, the corresponding application may be executed or a web page may be output.

The user interface in which the position or shape of the specific image changes along the circumference of the circular window portion 240 may be different from the above-described example. 21E,

Referring to FIG. 21E, when the cover 200 is covered, an image of the compass may be output to the circular window portion 240, that is, the exposed region 151 '. In this case, the output of the compass image may be performed in response to a specific control command being applied. For example, if a touch input (for example, a short touch, a long touch, a drag, a tap, etc.) set as a compass output command is applied to the window unit 240 while the exposure area 151 'is inactive, An image of the compass may be output to the exposed area 151 '.

The image of the compass outputted to the exposed region 151 'may be rotated in response to the movement of the position of the terminal. That is, the compass can be rotated to always point in the north-south direction regardless of the movement of the terminal.

At this time, the notification light 310 may be output to the boundary region of the window unit 240. In this case, the notification light 310 functions to notify that the image of the compass is outputted. As another example, if an event occurs in the terminal before or after the image of the compass is output, the notification light 310 may be output.

The mobile terminal described above can be applied not only to the configuration and method of the embodiments described above but also to the embodiments described above so that all or some of the embodiments may be selectively combined have.
