1 is a reference diagram illustrating a smart display monitor and a mobile terminal according to the present invention.

In FIG. 1, the smart display monitor 100 and the mobile terminal 200 are connected through a wired cable 300. However, according to an exemplary embodiment, a communication environment may be set based on wireless communication between the smart display monitor 100 and the mobile terminal 200.

The smart display monitor 100 may be connected to the mobile terminal to receive or provide predetermined data in both directions with the mobile terminal. The smart display monitor 100 will be described in more detail below with reference to FIGS. 2 to 4.

The mobile terminal 200 may provide predetermined data (eg, content data) to the smart display monitor 100.

Since the mobile terminal 200 may establish two-way communication with the smart display monitor 100, the mobile terminal 200 may receive information on a touch input input from the user by the smart display monitor 100 as input data. For example, even when a direct touch input is made to the smart display monitor 100 without direct touch input to the mobile terminal 200, the touch input optimized for the display environment of the mobile terminal 200 from the smart display monitor 100. The information can be received to perform processing as input data.

Although the mobile terminal 200 is described as an example of a portable computing device having a relatively small display screen, such as a smart phone and a tablet phone, the mobile terminal 200 may be implemented as a computing device having a display module of a predetermined size or more, such as a tablet PC. Of course it is obvious.

Wired cable 300 is a cable for connecting the mobile terminal 200 and the smart display monitor 100 by wire. For example, the wired cable 300 may be a cable capable of transmitting data according to a specific standard, such as a mobile high-definition link (MHL) cable.

FIG. 2 is a block diagram illustrating an embodiment of the smart display monitor of FIG. 1.

Referring to FIG. 2, the smart display monitor 100 may include a communication interface 110, a display 120, a video converter 130, and a controller 140. According to an embodiment, the smart display monitor 100 may further include at least one of the charge manager 150, the power terminal 151, the video input interface 160, the key input unit 180, and the speaker 190. .

The communication interface 110 may perform bidirectional communication with the mobile terminal 200.

In one embodiment, the communication interface 110 may include a wired communication module and a wireless communication module. For example, the communication interface 110 includes a mobile high-definition link (MHL) module that can be wired to the mobile terminal 200 and a wireless communication module that can perform short-range wireless communication with the mobile terminal 200. can do.

The display 120 may display predetermined image data. In addition, the display 120 may receive a touch input from the user. For example, the display 120 may be configured using a touch screen module.

The video converter 130 may convert the video data included in the content data provided from the mobile terminal 200 through the communication interface 110 to match the resolution of the display 120. For example, the video converter 130 checks the first resolution of the video data provided from the mobile terminal 200 and converts the checked first resolution into the second resolution of the display 120. Can be re-encoded.

The controller 140 may control other components of the smart display monitor 100 to display content data provided from the mobile terminal 200 or provide a touch input input from the user to the mobile terminal 200.

In one embodiment, the controller 140 displays the relative coordinate mode for the touch input of the display 120 based on the direction information of the mobile terminal 200, and reflects the relative coordinate mode from the touch input input from the user. Coordinate conversion to be provided as a user input to the mobile terminal 200.

In one embodiment, the control unit 140 generates an arrow having a direction corresponding to the direction information of the mobile terminal 200, and overlaps the arrow with the output image of the converted video data to deal with it as an OSD (On Screen Display). Coordinate mode can be displayed. For example, when the mobile terminal 200 is lying on the right side, the relative coordinate mode may be indicated by an arrow indicating the right direction. For another example, when the mobile terminal 200 stands vertically as shown in FIG. 1, the relative coordinate mode may be indicated by an arrow indicating an upward direction.

In one embodiment, the relative coordinate mode may include a portrait mode, a right landscape mode, and a left landscape mode according to the direction of the mobile terminal 200. Here, the controller may set the x-axis and the y-axis according to the relative coordinate mode, and perform coordinate remapping based on the coordinate information of the touch input input to the set x-axis and the y-axis according to the resolution of the mobile terminal. For example, when the relative coordinate mode is the right horizontal mode, the x-axis and the y-axis input to the display unit 120 are reduced according to the ratio of the resolution with the mobile terminal 200, and the coordinates are reflected by reflecting the x-axis and the y-axis as they are. You can remap it. This is because the display 120 may be directly associated with the right horizontal mode since the display 120 is generally long. As another example, when the relative coordinate mode is the left horizontal mode, coordinate remapping may be performed by inverting the x-axis input to the display unit 120 and reducing it according to the ratio of the resolution with the mobile terminal 200. In the case of the left landscape mode, it is assumed that the image is inverted. In this embodiment, regardless of the state in which the mobile terminal 200 is inverted, the user is inverted even when the user touches the display unit 120. As the input is reflected, the user's input becomes very easy.

In an exemplary embodiment, the controller 140 may independently perform the relative coordinate mode in displaying the converted video data, and the user's touch input may perform coordinate transformation by reflecting the relative coordinate mode. In more detail, the controller 140 automatically generates a direction for displaying the video data on the display unit 120 independently of the relative coordinate mode based on the resolution information of the video data converted by the video converter 130. However, the coordinate transformation may be performed by reflecting the relative coordinate mode with respect to the touch input input from the user. That is, the video data is optimized and displayed on the display unit 120, but the user's touch input on the displayed screen reflects the relative coordinate mode, thereby making the user's input easier.

In an embodiment, the controller 140 controls the content data to be provided through the MHL module of the communication interface 110, and the coordinate-converted user input is transmitted to the mobile terminal through the wireless communication module of the communication interface 110. 200). This is to allow for faster and easier control by avoiding consideration of interference or collision between channels by using different wireless channels for content data and user input.

According to an embodiment, the controller 140 may process the video input through the video input interface unit 160 to be given a higher priority than the video data included in the content data and output the video. For example, if an image is input from the rear camera by reversing the vehicle while watching a movie provided by the mobile terminal 200, the image of the rear camera is preferentially processed rather than the movie to provide safety and convenience to the user. For sake.

In one embodiment, the controller 140 may provide a request to turn off the display to the mobile terminal 200 when the charging power is being provided to the mobile terminal 200 by the charging manager 150. This has the effect of performing the charging of the mobile terminal 200 more quickly and comfortably.

The charge manager 150 may modulate the power provided through the power terminal 151 into the charge voltage of the mobile terminal 200 and provide the charge power to the mobile terminal 200 through the wired line. For example, the charge manager 150 may provide the modulated charging voltage to the mobile terminal 200 through a mobile high-definition link (MHL) cable.

The power supply terminal 151 is a means for receiving power from the outside. For example, the power supply terminal may receive power of a predetermined voltage from a vehicle power supply.

The video input interface 160 is an interface that can receive a separate external video input. For example, the video input interface 160 may be connected to a vehicle camera (eg, a rear camera) to receive a video input.

The key input unit 170 is a predetermined key set for user input.

The speaker 180 is a predetermined sound output means for its own audio output.

3 to 4 are reference views for explaining examples of output images of a smart display monitor and a mobile terminal according to an embodiment of the present invention.

In FIG. 3, the arrow 310 is an example of displaying a relative coordinate mode, and since the mobile terminal 200 is currently laid horizontally on the left side, it can be seen that the arrow 310 is indicated by the left arrow.

In FIG. 4, it can be seen that the mobile terminal 200 is laid on the right side so that the relative coordinate mode is represented by the right arrow 410 indicating the right horizontal mode. Even in such a case, it can be seen that the screen is output in accordance with the smart display monitor 100 without being inverted up and down. On the other hand, the touch input input by the user through the smart display monitor 100 converts the input coordinates according to the relative coordinate mode, it can be seen that can be converted to be correctly input in the right horizontal direction with respect to the mobile terminal 200. Can be.
