In addition to displaying the broadcast content BC, step S20 of displaying the contents of the message C may be performed.

The message C may be a short message service (SMS), a multimedia messaging service (MMS), an email, or the like. Even while the user is watching the broadcast content BC, the mobile terminal 100 may transmit / receive a phone call, a text message, an e-mail, or the like through the mobile communication module 112 of FIG. 1. When the mobile terminal 100 communicating with the mobile communication network receives the text message, the mobile terminal 100 may display the text message on the display unit 155 to notify the user. As described above, the message C may assume various cases. However, in the present embodiment, a case in which the message C is a received text message will be described, and description of the other case will be replaced.

The step S20 of displaying the content of the message C may include the step S21 of displaying the notification window 210, as shown in FIG. 4B.

In order to view a larger screen, the user generally views the broadcast content BC through the entire screen of the display unit 155. Accordingly, as shown in FIG. 5A, when a text message or the like is received, the notification window 210 may be displayed on the display unit 155. The notification window 210 may be minimized and displayed at the bottom of the display unit 155 in order to minimize interference with the user's viewing of the broadcast content BC. In addition, the notification window 210 may be displayed to be translucent so that the broadcasting content BC area overlapping the notification window 210 can be viewed.

If it is indicated that the message (C) has been received through the notification window 210, step (S23) to determine whether the notification window 210 is selected by the user may proceed.

As shown in FIG. 5B, the user may select the notification window 210 through a touch operation on the notification window 210. Various touch operations according to an embodiment of the present invention may include a proximity touch operation by a proximity sensor, including a touch operation in which the user selects the notification window 210. Hereinafter, a proximity touch operation will be described with reference to FIG. 5C, which is a conceptual diagram for describing a proximity depth of a proximity sensor.

As illustrated in FIG. 5C, when a pointer such as a user's finger is close to the touch screen, a proximity sensor disposed in or near the touch screen detects this and outputs a proximity signal.

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

The distance at which the proximity signal is output when the pointer approaches the touch screen is called a detection distance. By using a plurality of proximity sensors having different detection distances, the proximity depth can be known by comparing the proximity signals output from each proximity sensor.

In FIG. 5C, a cross section of a touch screen on which three proximity sensors capable of sensing three proximity depths is disposed is illustrated. Of course, proximity sensors that detect less than three or more than four proximity depths are also possible.

Specifically, when the pointer is completely in contact with the touch screen (D0), it is recognized as a touch touch. When the pointer is positioned below the D1 distance on the touch screen, the pointer is recognized as a proximity touch having a first proximity depth.

When the pointer is located at a distance of more than D1 and less than D2 on the touch screen, the pointer is recognized as a proximity touch having a second proximity depth. When the pointer is positioned away from the D2 distance or more than the D3 distance on the touch screen, the pointer is recognized as a proximity touch having a third proximity depth. When the pointer is positioned more than the distance D3 on the touch screen, the proximity touch is recognized as released.

Accordingly, the controller 180 may recognize the proximity touch as various input signals according to the proximity distance and the proximity position of the pointer touch screen, and perform various operation control according to the various input signals.

When the touch signal for the notification window 210 is received, step S25 of displaying the contents of the message C on the display window may be performed.

As shown in FIG. 5D, the contents of the message C may be displayed through the display window 212. The display window 212 may adjust transparency. When the display window 212 is semi-transparently displayed, even if the display window 212 is displayed on the display unit 155, it is possible to identify a portion of the broadcast content BC overlapping the display window 212. Accordingly, the user can watch the broadcast content BC and check the text message, the e-mail message, etc. displayed on the display window 212.

After displaying the contents of the message C, a step S30 of determining whether the first touch signal has been received is performed.

In one embodiment of the present invention, the first touch signal means a touch signal for a specific position of the display window 212. Specifically, it means a touch operation for a specific position that does not include a drag or flicking operation. As described above, the first touch signal may be a signal by a proximity touch.

As shown in FIG. 5E, the user may touch the inner region of the display window 212 with the tip of the finger F or the like. When the user touches the internal area of the display window 212, a first touch signal is generated, and the controller (180 of FIG. 1) receives the first touch signal.

When the first touch signal is received, step S40 of displaying the first and second indicators I1 and I2 around the display window 212 may be performed.

The first indicator (I1) is a letter or symbol representing the functions associated with the message (C). In other words, if the message (C) is a received text message, "Confirm" to treat the text message as read, "Reply" to send the text message to the sender of the text message, "Save" to save the text message in the archive In addition, the “delete” function of deleting the text message may be displayed as the first indicator I1.

When there are four or less functions to be displayed by the first indicator I1, each of the first indicators I1 is displayed at 90 degree angles on the upper, lower, left, and right sides of the display window 212, respectively, Can correspond. In addition, when there are more than four, it may be arranged around the display window 212 at appropriate intervals. However, in order to improve the identification power and facilitate the touch operation, the function indicated by the first indicator I1 may be limited to four or less.

The second indicator I2 is displayed so that the user can clearly recognize the direction in which the first indicator I1 is located. Accordingly, the second indicator I2 may be an arrow or the like displayed along an imaginary line from the display window 212 to each of the first indicators I1.

The first and second indicators I1 and I2 are displayed when the user touches the display window 212 and the first touch signal is received by the controller (180 of FIG. 1). Accordingly, viewing restriction of the broadcast content BC due to the display of the first and second indicators I1 and I2 may be minimized.

When the first and second indicators I1 and I2 are displayed, a step S50 of determining whether the second touch signal is received may be performed.

As shown in FIG. 5F, the second touch signal is a touch signal that is continuously generated in the direction of the first indicator at the point where the first touch signal is generated. That is, a drag or flicking operation is performed after the first touch signal is generated.

After reading the content displayed on display 212, the user must determine how to handle display 212 and text messages. If the user wants to delete the text message, the user may perform a desired function by dragging or flicking the touched direction toward the first indicator I1 marked as “delete”.

FIG. 5G illustrates a trajectory process of the second touch signal by the controller (180 of FIG. 1). As shown in FIG. 5F, the user may want to drag in the “delete” direction displayed at the bottom of the display window 212. However, the user's intention was the first trajectory R1 due to the instability of the touch operation using a finger or a stylus pen, etc., but the second trajectory R2 substantially out of this is received as the second touch signal. Can be. In this case, the controller (180 of FIG. 1) may compare the X-axis distance a and the Y-axis distance b of the second trajectory R2 to execute a function having the larger value. Meanwhile, although FIG. 5G assumes that four functions are displayed along the X and Y axes, the virtual axis may be provided to correspond to the number when the displayed functions are less than or more than four.

When the second touch signal is received, the display window 212 gradually becomes transparent, and the movement of the display unit 155 toward the outside (S60) may proceed.

As shown in FIG. 5F, a second touch signal facing downward may be received by the controller (180 of FIG. 1) by the user dragging in the “delete” direction displayed at the lower side.

As shown in FIG. 5H, when the second touch signal in the downward direction is received, an operation in which the first position display window 212 slides and moves in the touch signal direction may occur. The display window 212 slidably moved in the touch signal direction disappears from the display unit 155 as a result. As the display window 212 disappears while moving in the touch signal direction C, the user can clearly reconfirm that the function he or she wished to select was correctly selected.

While the display window 212 moves in the second proximity touch signal direction C, the transparency of the display window 212 may be adjusted. That is, it means that the display window 212 becomes more transparent and disappears. Therefore, even when the display window 212 disappears, the viewing of the broadcast content BC may be naturally performed.

When the display window 212 disappears, operation S70 may be performed in which a function selected by a user is performed.

That is, when the user selects the delete function of the received message, the message may be deleted and the result may be displayed through the pop-up window 214 as shown in FIG. 5I.

In operation S50 of determining whether the second touch signal is received, determining whether the first touch signal is released when the second touch signal is not received may be performed (S80). That is, after the user performs a touch operation for generating the first touch signal, it is determined whether the touch is released without performing the drag or flaking touch operation for generating the second touch signal.

When the first touch signal is released, the step S90 of maintaining the first and second indicators I1 and I2 for a predetermined time may be performed.

Even when the user releases the touch operation that has generated the first touch signal without a subsequent operation, the user can consider what function to select by maintaining the first and second indicators I1 and I2 for a predetermined time. can do.

Meanwhile, when the function selected by the user through the first touch signal is a function displayed on the entire display unit 155, the time shift function may be executed. That is, when the user selects 'Reply' from the first indicator I1 shown in FIG. 5F, a window for executing the reply function is displayed over the entire surface of the display unit 155 to display the broadcast content (BC). ) May not be able to watch smoothly. In this case, the broadcast content BC may be stored in the memory 160 of FIG. 1 from the moment when the user cannot watch. The stored broadcast content BC may be reproduced when the execution of another function is ended and the display unit 155 is able to display the broadcast content BC. In addition, by storing the broadcast content BC that is currently being received and simultaneously storing the broadcast content BC that has been stored, the user can watch the broadcast content BC continuously without interruption.

6 is a flowchart illustrating an information display method of a mobile terminal according to another embodiment of the present invention, and FIG. 7 is a diagram illustrating an operation of the mobile terminal of FIG. 6.

As shown in these figures, when the first touch signal is received, the mobile terminal 100 according to another embodiment of the present invention may include acquiring coordinates of the touch point 216 (S101).

As described above, the first touch signal is generated by the user touching the inside of the display window 212. In a typical usage environment, the user may touch the touch point 216 some distance from the center point 218, rather than touching the exact center point 218 inside the display window 212. Therefore, the mobile terminal 100 according to another embodiment of the present invention may display the first and second indicators I1 and I2 on the virtual line orthogonal to the obtained coordinates (S103). Specifically, as illustrated in FIG. 7, the first and second indicators I1 and I2 may be displayed on the top, bottom, left, and right sides of the touch point 216.

Since the first and second indicators I1 and I2 are disposed around the touch point 216, the drag or flicking direction for generating the second touch signal can be intuitively recognized. That is, in order to execute the “delete” function, it is possible to intuitively recognize that the user can always drag or flak downward with respect to the touch point 216, and, of course, the usability can be increased. The touch operation may be recognized by the controller 180 of FIG. 1 without an error. As such, when the first indicator I1 is located above, below, left, and right of the center point 218 irrespective of the touch point 216, the user may move left and down to execute the “delete” function. Or it may be clearly distinguished in consideration of the fact that it must be dragged or flicking obliquely downward.

8A and 8B illustrate an operation of a mobile terminal according to another embodiment of the present invention.

As shown in these figures, in the mobile terminal 100 according to another exemplary embodiment of the present invention, the display window 212 may be displayed at the bottom of the display unit 155.

Since the display window 212 is displayed as a single line of text window at the bottom of the display unit 155, an area that prevents viewing of the broadcast content BC may be minimized.

The display window 212 displayed as a text window may display the received text in a scrolling caption manner. That is, the received text message or e-mail message is represented by a single line of text, which means that the text is displayed in a manner that is displayed while scrolling left, right, or up and down.

    As shown in FIG. 8B, the first touch signal 212 may be generated by the user touching the display window 212. When the first proximity touch signal 212 is generated, since the first and second indicators I1 and I2 are displayed based on the touched point, they are similar to those of the above-described embodiments, and detailed description thereof will be replaced with the above description. Do it.

In the above-described embodiments, the case in which the displayed message is a received text message has been mainly described. However, the message is received by the mobile terminal while viewing the broadcast content such as the received e-mail message and needs to inform the user of the reception fact. Of course, content is possible.
