     DETAILED DESCRIPTION 
     Reference will now be made in detail to the embodiments, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below to explain the embodiments by referring to the figures. 
     Certain exemplary embodiments will now be described in greater detail with reference to the accompanying drawings. 
     In the following description, same drawing reference numerals are used for the same elements even in different drawings. The matters defined in the description, such as detailed construction and elements, are provided to assist in a comprehensive understanding of the embodiments. Thus, it is apparent that the exemplary embodiments can be carried out without those specifically defined matters. Also, well-known functions or constructions are not described in detail since they would obscure the embodiments with unnecessary detail. 
     The exemplary embodiments of the present disclosure may be diversely modified. Accordingly, specific exemplary embodiments are illustrated in the drawings and are described in detail in the detailed description. However, it is to be understood that the present disclosure is not limited to a specific exemplary embodiment, but includes all modifications, equivalents, and substitutions without departing from the scope and spirit of the present disclosure. Also, well-known functions or constructions are not described in detail since they would obscure the disclosure with unnecessary detail. 
       FIG. 1  is a view for explaining an embodiment example of a remote control apparatus according to an embodiment of the present disclosure. 
     The remote control apparatus  100  is a configuration for controlling operations of a display apparatus. In an embodiment of the present disclosure, the remote control apparatus  100  may be a remote controller configured to emit an infrared ray of a predetermined frequency to a display apparatus to control operations of the display apparatus. Herein, the display apparatus may receive the emitted infrared ray, convert the infrared ray into electric signals corresponding to the frequency of the infrared ray, to perform various operations such as converting a channel and adjusting volume and the like. 
     Meanwhile, the user may request the display apparatus to provide a content using the remote control apparatus  100 , and control the display apparatus providing the content. For example, the user may select a channel using the remote control apparatus  100 , and the display apparatus may display a content of the selected channel through the remote control apparatus  100 . 
     The remote control apparatus  100  includes a plurality of control surfaces. The user may perform various control operations of selecting a channel of the display apparatus, adjusting volume, selecting an external input mode, and executing an application program and the like using the plurality of control surfaces. For this purpose, the plurality of control surfaces may be realized as at least one of a key pad including various function keys, number keys and special keys; a touch pad for sensing movements of fingers; and a track pad. 
     Herein, the plurality of control surfaces may each be mapped to each of a plurality of display areas or display regions provided on the screen of the display apparatus, and control each display area using the key pad, touch pad and track pad provided in each of the plurality of control surfaces. 
     For example, a user interface  120  may be configured as a first control surface  121 , second control surface  122  and third control surface  123  as illustrated in  FIG. 1 , in which case three areas of the screen of the display apparatus may each be mapped to a control surface. Herein, the plurality of display areas provided on the screen of the display apparatus may be matched to a layout of the plurality of control surfaces  121 ˜ 123  of the user interface  120 . More specific explanation thereof will be made hereinafter with reference to  FIGS. 4 and 6 . 
     Meanwhile, the plurality of control surfaces  121 ˜ 123  may have a physically divided structure. That is, the physically divided plurality of control surfaces  121 ˜ 123  may serve a function of enabling the user to input a command desired by the user by only touching. Herein, the physically divided structure may be for example a structure including a groove between the plurality of control surfaces  121 ˜ 123 , or a structure where the plurality of control surfaces  121 ˜ 123  protrude on a plane. However, there is no limitation thereto, and thus the physically divided structure may be one of various structures that enable differentiating between each control surface by only touching. 
     The user terminal apparatus  100  may sense a touch interaction on each of the plurality of control surfaces  12 ˜ 123 , generate a signal corresponding to the touch interaction, and transmit a corresponding signal to the display apparatus through the communicator  110 , thereby controlling the display apparatus. 
     More specifically, the user terminal apparatus  100  may generate a direction signal corresponding to a direction of the touch interaction, and control a function corresponding to the display apparatus according to the direction signal. For example, the user terminal apparatus  100  may perform a function of volume up according to an upward direction signal generated according to the upward direction touch interaction. 
     Furthermore, as illustrated in  FIG. 1 , the user terminal apparatus  100  may be provided with keypads  124 ˜ 126  for executing a predetermined function besides the plurality of control surfaces  121 ˜ 123 . 
     Furthermore, the plurality of control surfaces  121 ˜ 123  may have an arch structure of a certain gradient. More specifically, as illustrated in  FIG. 1 , the plurality of control surfaces  121 ˜ 123  may be configured to have an arch structure where a second control surface adjacent to a first control surface forms a predetermined angle with the first control surface, and a third control surface adjacent to the second control surface forms a predetermined angle with the second control surface. Accordingly, it is possible to differentiate each of the plurality of control surfaces  121 ˜ 123  by touching without even seeing the user terminal apparatus  100 . 
     Meanwhile, the user terminal apparatus  100  may be embodied as one of various formats such as a portable mobile phone, PMP, PDA, and notebook and the like. 
       FIG. 2  is a block diagram schematically illustrating a configuration of a remote control apparatus or device according to an embodiment of the present disclosure. 
     According to  FIG. 2 , the remote control apparatus according to an embodiment of the present disclosure includes a communicator  110 , user interface  120  and controller or processor  130 . 
     The communicator  110  is a configuration for performing communication with the display apparatus  200 . More specifically, the communicator  110  may perform communication with the display apparatus  200  in a short distance wireless communication method such as an RF (Radio Frequency: RF) communication including Bluetooth, Zigbee, and Wi-Fi or Infrared Ray (IP) communication. For this purpose, the communicator  110  may be provided with a communication module that may be used in each of the communication methods. 
     In response to a predetermined event occurring, the communicator  110  may perform communication with the display apparatus  200  in a pre-defined communication method and be in an interlocked state. Herein, the interlocked state may be a state where communication between the remote control apparatus  100  and display apparatus  200  is initiated, where network is being formed, or where a device pairing is being performed. 
     For example, in a case of performing communication in a Bluetooth communication method, the communicator  110  may perform pairing with the display apparatus  200  through a Bluetooth communication module, and be in a state where it may communicate with the display apparatus  200 . 
     Furthermore, in a case of having a Zigbee communication module, the communicator  110  may perform pairing with the display apparatus  200  through Zigbee communication module, and be in a state where it may communicate with the display apparatus  200 . 
     Furthermore, the communicator  110  may perform wireless communication with the display apparatus  200  using Wifi and the like. For example, the communicator  110  may be directly connected to the display apparatus  200  without going through a separate network through a Wifi communication module and perform communication or may be connected to the network using an access point and perform communication. As such, the communicator  110  may perform communication with the display apparatus  200  using various communication methods. 
     Herein, a predetermined event may occur in at least one of the remote control apparatus  100  and display apparatus  200 . For example, an event may be a user command of selecting the display apparatus  200  as a subject device for control in the remote control apparatus  100 , or an event where the display apparatus  200  is turned on. 
     The user interface  120  is a configuration for inputting a user command. The user interface  120  may be provided with a plurality of control surfaces in order to receiving input of various user commands for controlling functions of the display apparatus. Accordingly, the user terminal apparatus  100  may be realized to include a touch sensor or an OJ (Optical Joystick) sensor using optic technology. 
     Herein, the plurality of control surfaces of the user interface  120  may be realized in various formats, but they may have a physically differentiated structure such that a user may recognize a format of manipulation that he/she is inputting by only touching. Especially, the plurality of control surfaces may be configured in an arch structure where the surfaces form a predetermined angle with one another, thereby providing a different touch through a gradient of each control surface. Thus, it is possible to refer that the plurality of control surfaces are differentiated into ridges. 
     Meanwhile, the user interface  120  may provide a UI screen representing functions allocated on each control surface using a light emitter provided below the plurality of control surfaces. For example, in response to a function allocated on a first control surface being a channel selecting button, the first control surface may display an arrow icon representing channel selecting through the light emitter. Furthermore, in response to a function allocated to a third control surface being a volume adjusting button, the third control surface may display a +/− icon representing volume adjusting through the light emitter. 
     Meanwhile, according to an arrangement state (width mode, length mode) of the remote control apparatus, the UI screen being displayed on the plurality of control surfaces may change. Detailed explanation thereof will be made with reference to  FIG. 5  hereinafter. 
     The processor  130  performs a function of controlling overall operations of the remote control apparatus  100 . 
     Especially, according to a user command being input through at least one of a plurality of control surfaces provided in the user interface  120 , the processor  130  may control the communicator  110  to transmit a signal for controlling a display area mapped with a control surface where the user command has been input to the display apparatus. 
     That is, regarding the plurality of control surfaces, the processor  130  may control each of the display areas separately using mapping information mapped with the display area such that the plurality of display areas are controlled separately. Herein, the plurality of control surfaces may have a layout that matches with a plurality of display areas, and the user may control each display area by intuitive manipulation. For example, the screen being displayed in the display apparatus may be divided into a first area, second area and third area sequentially, and accordingly, the remote control apparatus  100  is provided with a first control surface, second control surface and third control surface from the left side to have a layout that matches with the first to third areas. 
     In such a case, the first area may be controlled by the first control surface, the second area may be controlled by the second control surface, and the third area may be controlled by the third control surface. 
     Herein, the processor  130  may transmit a signal for controlling a UI screen displayed on an display area mapped with a control surface where a user command has been input of among a plurality of UIs (User Interfaces) provided in each of the plurality of display areas. 
     The user may control the UI screen provided in each display area through the remote control apparatus  100 . For example, the user may control a channel selecting UI displayed on the first area of the display screen to change a channel by touching an arrow icon displaying a channel selecting function allocated on the first control surface. 
     Meanwhile, the remote control apparatus  100  may further include a mode state detector configured to determine an arrangement state of the remote control apparatus  100  and to detect a length mode state or width mode state according to the determined arrangement state, and the processor  130  may control a UI screen corresponding to the detected mode state to be displayed on each of the plurality of control surfaces. 
     That is, the user may divide the remote control apparatus  100  by a length and width according to attributes of the UI screen being displayed. For example, in a case of merely selecting a channel or adjusting volume, it is convenient to divide the remote control apparatus  100  by length and manipulate the same, but in a case of selecting a replay section or inputting a letter while watching a movie, it is convenient to divide the remote control apparatus  100  by width and manipulate the same. 
     Accordingly, the processor  130  detects whether the arrangement state of the remote control apparatus  100  is a length mode state or a width mode state, and allocates a function corresponding to the detected mode state to the plurality of control surfaces. For example, in response to the arrangement state of the remote control apparatus  100  being a length mode state, a channel selecting function is allocated to the first control surface, but in response to the arrangement state of the remote control apparatus  100  being a width mode state, a replay section selecting function may be allocated. At the same time, the processor  130  may control a light emitter such that a UI screen corresponding to the detected mode state is displayed on each of the plurality of control surfaces. 
       FIG. 3  is a block diagram schematically illustrating a configuration of a display apparatus according to an embodiment of the present disclosure. 
     The display apparatus  200  is a configuration for displaying a content being received through an image signal such as a TV signal. The display apparatus  200  may output an image and sound to outside at the same time and provide various types of audiovisual contents to the user. 
     The display apparatus  200  may be provided with infrared receiving means configured to receive infrared ray emitted from the remote control apparatus  100  by an IR communication method or transmission means configured to receive a predetermined control command by an RF communication method from the remote control apparatus  100 , for example an RF communication module. 
     The display apparatus  200  may be any type of display apparatus that may be controlled by the remote control apparatus  100 . For example, the display apparatus  200  may be any type of display apparatus that may display images through a screen such as a TV including smart TVs and computer and the like. 
     According to  FIG. 3 , the display apparatus  200  according to an embodiment of the present disclosure includes a display  210 , communicator  220 , and a controller or processor  230 . 
     The display  210  is a configuration for providing a content screen. Especially, the display  210  may divide the screen being displayed into a plurality of display areas, and provide each of a plurality of UI screens in each of the display areas. The display  210  may display an environment setting menu, information on adjusting a channel and volume, and various contents information and the like, and the contents being displayed may include an image and text that represent the contents. The display  210  may be set to display only some of the plurality of UI screens. 
     The plurality of display areas may be divided in various ways. For example, the display areas may be divided into three areas in a length or width direction, or into two areas or in four or more areas. Such a dividing method may be predetermined according to a layout of a plurality of control surfaces mapped to each of the display areas. 
     The display  210  may be realized as an LCD (Liquid Crystal Display Panel) or OLED (Organic Light Emitting Diodes), but there is no limitation thereto. Furthermore, the display  210  may be realized as a flexible display, or transparent display and the like in some cases. 
     The communicator  220  is a configuration for performing communication with the remote control apparatus  100 . The communicator  220  may communicate with the display apparatus  100  according to a short distance wireless communication method such as an RF communication or infrared (IR) communication including Bluetooth, Zigbee, and Wi-Fi and the like. For this purpose, the communicator  220  may be provided with a communication module that may be used in each communication method. 
     The display apparatus  200  is provided with a communication module for performing communication in the same manner as the communicator  110  of the remote control apparatus  100 . The method for performing communication with the display apparatus  200  was explained with reference to  FIG. 2 , and thus repeated explanation will be omitted. 
     The processor  230  is a configuration for controlling overall operations of the display apparatus  200 . 
     Especially, in response to receiving a control signal corresponding to a user command input through at least one of a plurality of control surfaces provided in the remote control apparatus  100 , the processor  230  may control a display area corresponding to the received control signal of among the plurality of display areas. Herein, as aforementioned, each of the plurality of display areas provided in the screen is mapped with a plurality of control surfaces provided in the remote control apparatus  100 . 
     Furthermore, the processor  230  may control a UI screen corresponding to a control signal received from the remote control apparatus  100  of among a plurality of UI screens provided in each of a plurality of display areas, and may divide the screen in a plurality of display areas in a length or width direction based on attributes of the UI screen to be displayed on the screen and provide a UI screen. 
     Furthermore, in response to receiving a control signal according to a touch input of crossing the plurality of control surfaces from the remote control apparatus  100 , the processor  230  may control the plurality of display areas such that a different UI screen is sequentially displayed thereon, and in response to receiving a control signal according to a press input from the remote control apparatus  100 , the processor  230  may control such that at least a portion of a different UI screen is displayed in each of a plurality of display areas at the same time based on the press input method. Specific explanation thereof will be made hereinafter with reference to  FIGS. 8 a    to  9   c.

Accordingly, in response to a user command being input using the first control surface  121 , a signal for controlling the first area  10  mapped with the first control surface  121  may be transmitted to the display apparatus  200 . In such a case, a signal for controlling a UI screen provided in the first area  10  of among the plurality of display areas  10 ˜ 30  may be transmitted to the display apparatus  200 . 
     Meanwhile, as illustrated in (b) of  FIG. 4 , the second control surface  122  of the remote control apparatus  100  is mapped with the second area  20  of among the plurality of display areas of the screen provided in the display apparatus  200 .
