According to an exemplary embodiment, the display  120  may include a touch sensor configured to detect a touch. 
     According to various exemplary embodiments, the communication device  130  may support performing communication with the at least one external device  190 . The at least one external device  190  may be an electronic device, such as a smart phone, a PDA, or a tablet PC, capable of transmitting and receiving data by communicating with the display control apparatus  100 . 
     According to an exemplary embodiment, the communication device  130  may include at least one of a short-range communication device, a wired communication device, and a wireless communication device. For example, the short-range communication device may include various communication devices such as a Bluetooth module, an infrared communication device, a radio frequency identification (RFID) communication device, a wireless local access network (WLAN) communication device, an NFC communication device, a Zigbee communication device, or the like. For example, the wired communication device may include various communication devices such as a local area network module, a wide area network module, a value added network module, a universal serial bus (USB) module, a high definition multimedia interface (HDMI) module, an RS-232 (recommended standard 232) module, and the like. For example, the communication device  130  may include various communication devices such as, in addition to a Wi-Fi module and a wireless broadband module, global system for mobile communication (GSM), code division multiple access (CDMA), wideband code division multiple access (WCDMA), universal mobile telecommunications system (UMTS), time division multiple access (TDMA), long term evolution (LTE), 4G, 5G, or the like. 
     According to an exemplary embodiment, the communication device  130  may be configured to support a specified protocol that can be used for communication between components inside the vehicle  200 . For example, a controller area network (CAN), a local interconnection network (LIN), a FlexRay, or the like may be used as the specified protocol. 
     According to various exemplary embodiments, the memory  140  may be configured to store commands or data related to at least one other component of the display control apparatus  100 . According to an exemplary embodiment, the memory  140  may include programs, algorithms, routines, and/or instructions related to the operation (or control) of the display control apparatus  100 . For example, the memory  140  may include at least one program module instructing each operation of the processor  150  mentioned in various exemplary embodiments of the present disclosure. 
     According to various exemplary embodiments, the processor  150  may be operatively connected to components (e.g., the input device  110 , the display  120 , the communication device  130 , and the memory  140 ) and may be configured to perform overall operations of the display control apparatus  100 . 
     According to an exemplary embodiment, the processor  150  may be configured to output first information through the display  120 . The first information may be related to a function operated through the vehicle  200  and/or the external device  190 . As at least some of the functions operated through the vehicle  200 , an electronic map service, a vehicle status check function, a voice memo storage function, and the like may be included. In addition, at least some of the functions operated through the external device  190  may include a phone call function, a multimedia content playback function, and the like. For example, as illustrated in (a) of  FIG.  3 B , the first information including a menu  310  causing execution of at least one function (e.g., an electronic map, a phone call, a voice memo, a setting mode, or the like.) may be output through the display  120  of the vehicle  200 . 
     According to an exemplary embodiment, the processor  150  may be configured to detect the occurrence of a specified event while outputting the first information. The specified event may be a situation in which the driver does not recognize at least a part of the first information output through the display  120 . 
     For example, as illustrated in  FIG.  3 A , the specified event may include a situation in which at least a part of the display  120  is covered by the external device  190  in the vehicle  200 . However, this is only an example, and various exemplary embodiments are not limited thereto. For example, in addition to the external device  190 , a situation in which a driver&#39;s view on the display  120  is obstructed by other objects such as air fresheners or dolls may also be detected as the specified event. The detection of the specified event will be described later with reference to  FIGS.  5  to  7 B . 
     According to an exemplary embodiment when the occurrence of the specified event is detected, the processor  150  may be configured to control an output of the first information output through the display  120 . Controlling the output of the first information may mean outputting a part of the first information that is covered with the external device  190  through the external device  190  (e.g., the display of the external device  190 ). By controlling the output of the first information, it is possible to solve the problem that the driver does not recognize at least a part of the first information that is covered with the external device  190 . 
     For example, as illustrated in (b) of  FIG.  3 B , it may be assumed that at least a part (e.g., a menu that causes execution of the electronic map illustrated in (a) of  FIG.  3 A ) of the first information is covered with the external device  190  in a state in which the first information composed of the menu  310  causing execution of a function operated through the vehicle  200  and/or the external device  190  is output through the display  120 . In this case, the display  120  may be divided into a visible area that is not covered with the external device  190  and can be seen by the driver, and an invisible area that is not visible by the driver because it is covered with the external device  190 . In this regard, the processor  150  may be configured to provide at least a part of the first information corresponding to the invisible area of the display  120  (e.g., information covered by the external device  190  and not recognized by the driver among the first information) to the at least one external device  190  connected through communication. Accordingly, as illustrated in (c) of  FIG.  3 B , at least a part  310 - 2  of the first information corresponding to the invisible area may be output through the external device  190 , and at least a part  310 - 1  of the first information corresponding to the visible area may be output through the display  120 . In this regard, the external device  190  may be configured to adjust an output position and/or an output size with respect to at least a part of the first information. For example, at least a part of the first information may be output a full screen or a partial screen (e.g., a pop-up screen, a split screen, or the like.). of the external device  190 . 
     As described above, among the first information output through the display  120  of the vehicle  200 , some information corresponding to the invisible area may be output through the external device  190 . In this regard, the processor  150  according to various exemplary embodiments may be configured to determine an output method for the first information based on the size of the invisible area (or a degree of covering by the external device  190 ). 
     According to an exemplary embodiment, the output method for the first information may include a first mode for outputting the first information through the display  120  and the external device  190 , and may include a second mode for outputting the first information only through the external device  190 . 
     For example, when it is determined that the size of the invisible area covered by the external device  190  corresponds to a specified first level, the processor  150  may be configured to output the first information in a first output method. For example, when the size of the invisible area corresponds to the specified first level, as illustrated in (a) of  FIG.  4 A , less than a specified level of the display  120  is covered by the external device  190 , and there is relatively many an uncovered part  410  of the display  120 , so that the output of the first information may be possible. In this case, as illustrated in (a) of  FIG.  4 B , the processor  150  may be configured to output a part A- 2  of first information ‘A’ corresponding to the invisible area through the external device  190 , and may output the other part A- 1  of the first information ‘A’ corresponding to the visible area through the uncovered part  410  of the display  120 . 
     As another example, when it is determined that the size of the invisible area covered by the external device  190  corresponds to a specified second level, the processor  150  may be configured to output the first information in a second output method. For example, when the size of the invisible area corresponds to the specified second level, as illustrated in (b) of  FIG.  4 A , the display  120  is covered by the external device  190  by a specified level or more, relatively large external device  190  is mounted in the vehicle  200 , or a plurality of external devices  190  are mounted in the vehicle  200 , and uncovered part  420  of the display  120  is relatively small, so that the output of the first information may be actually impossible. In this case, as illustrated in (b) and (c) of  FIG.  4 B , the processor  150  may be configured to output all (A- 1  and A- 2 ) of the first information ‘A’ through the external device  190 . In this regard, the processor  150  may be configured to limit an operation of the display  120  or may be configured to allow display  120  to operate in a low power mode while the first information is output through the external device  190 . In this case, as illustrated in (b) of  FIG.  4 B , no information may be output through the uncovered part  420  of the display  120 , and thus unnecessary power consumption may be prevented from occurring. As another example, as illustrated in (c) of  FIG.  4 B , the processor  150  may be configured to output predetermined information ‘B’ through the uncovered part  420  of the display  120  while the first information is output through the external device  190 . The predetermined information ‘B’ may be information different from the first information that has been output (or currently output through the external device  190 ) through the display  120 . 
     As described above, among the first information output through the display  120  of the vehicle  200 , some information corresponding to the invisible area may be output through the external device  190  depending on an occurrence of the specified event. 
     According to an exemplary embodiment, the specified event may be generated by a driver&#39;s input. For example, when an input set to generate a specified instruction is detected, the processor  150  may output some information corresponding to the invisible area through the external device  190 . The specified instruction may be an instruction for instructing to output information on the invisible area through the external device  190 , and may be generated by at least one of a hard key input, a jog shuttle input, a touchpad input, or a voice input. 
     According to an exemplary embodiment, the occurrence of the specified event may be related to detecting an approach or a presence of the external device  190 . In this regard, the display control apparatus  100  may further include the sensor  160 . For example, as illustrated in  FIG.  5   , the sensor  160  may include at least one sensor  510  disposed around the display area of the display  120 , for example, along the edge of the display area. The at least one sensor  510  may be configured to irradiate predetermined light and to receive the light reflected from the object. However, this is only an example, and various exemplary embodiments are not limited thereto, and any sensor may be used as the configuration of the sensor  160  as long as it may detect the approach or presence of the external device  190 . 
     For example, when the at least one sensor  510  detects the approach or presence of the external device  190 , the processor  150  may be configured to output some information corresponding to the invisible area through the external device  190 . In this regard, the processor  150  may be configured to determine the position, direction, and size of the invisible area based on the number of sensors and the position of the sensor that detects the approach or presence of the external device  190 . 
     According to another embodiment, the occurrence of the specified event may be determined through an image analysis. In this regard, the display control apparatus  100  may include the at least one camera  170 . For example, the at least one camera  170  may be provided in a head lining  600  that is built into the ceiling of the vehicle  200 , as illustrated in  FIG.  6 A , and may have the angle of view capable of photographing the display  120 . However, this is only an example, and various exemplary embodiments are not limited thereto. For example, the at least one camera  170  may be located at any position where an image including the display  120  can be captured, such as an overhead console, a center console, and the like, without limitation. 
     For example, as illustrated in  FIG.  6 B , the processor  150  may be configured to divide an image  610  acquired through the at least one camera  170  into a plurality of areas  612 , and then may be configured to identify the invisible area of the display  120  covered by the external device  190 . For example, the processor  150  may be configured to distinguish an area corresponding to the external device  190  and an area corresponding to the display  120  from the divided areas, and may be configured to identify the position, direction, size, and the like of the invisible area through the ratio thereof. However, this is only an example, and the invisible area may be identified using various known image analysis methods. 
     According to another embodiment, the specified event may be related to a state of mounting the external device  190 . In this regard, the display control apparatus  100  may include at least one cradle  700  configured to be detachably attached to at least a part of the display  120  as illustrated in  FIGS.  7 A and  7 B . For example, the cradle  700  may be an articulated holder that enables parallel movement and rotation and fixation at any angle up, down, left, and right with respect to the external device  190  in a mounted state. However, this is only an example, and various exemplary embodiments are not limited thereto.
