Also, at least one video device may be connected to the display device 1, and additional content may be provided through a video signal input from the video device. Furthermore, the display apparatus 1 may store another content in the storage unit 14, and the content stored in the storage unit 14 may be provided.

The display device 1 uses a UI menu for convenient retrieval of contents that can be provided through various paths as described above. Fig. 5 shows an example of a UI menu 131 displayed by the display device 1 shown in Figs. 1 and 2. Fig. The main body control unit 16 controls the image processing unit 12 to display the UI menu 131 through the display unit 13. [

The UI menu 131 includes a plurality of UI items 132 corresponding to each of a plurality of contents that can be provided, as shown in Fig. 5, a plurality of UI items 132 are arranged in a lattice shape, but the arrangement form of the plurality of UI items 132 is not limited to this, and may be arranged in various forms. For example, the information on the content includes the channel number 133, the channel name 134, the title 135, and the like of the corresponding content. Although not shown, the information on the content may include a thumbnail image of the content. For convenience of illustration, the content information for some UI items 132 in FIG. 5 is omitted.

A user can search for and select a desired content using a plurality of UI items 132. [ Body control 16 highlights any UI item 132 so that the user can select any of a plurality of UI items 132 (see reference numeral 136 in FIG. 5). The main body control section 16 moves the highlight 136 to another UI item 132 and displays it according to a user's instruction using the key input section 22 and / or the touch input section 21 of the remote control device 20, The user can select the content of the UI item 132 when the desired UI item 132 is highlighted.

The content that can be displayed through the plurality of UI items 132 is a part of the entire contents that the display device 1 can provide. The display device 1 displays a UI item 132 (hereinafter, referred to as a "page ") corresponding to the content that can be displayed on the screen at a time, taking into consideration a situation where all of the contents can not be displayed all at once on the screen. The UI menu 131 may include information 137 and 138 about the page to which the content of the currently displayed UI item 132 belongs. Reference numeral 137 denotes the second page among the 7 pages in total, and numeral 138 denotes a bar-shaped indicator.

Further, the display device 1 can classify the entire contents into categories and display the UI items 132 of the contents according to the categories. Examples of such categories may include an entire channel, TV, radio, external input (corresponding to content from a video device), and the like. The UI menu 131 may include information 139 of the category to which the content of the currently displayed UI item 132 belongs.

The main body control unit 16 sets the currently displayed UI item 132 to the UI item 132 corresponding to the content belonging to another page other than the currently displayed page or the content belonging to another category other than the currently displayed category, Can be displayed and displayed. The instruction of the user corresponding to such switching of the page and / or category (hereinafter also referred to as "movement") may be made by the key input unit 22 and / or the touch input unit 21 of the remote control device 20 . For example, the key input unit 22 includes four buttons arranged vertically, horizontally, and vertically. When the upper and lower buttons are pushed, movement between the categories is performed. When the buttons arranged to the left and right are pushed, have. Here, in order that the contents to be newly displayed when the movement between the page and / or the category is made can be determined, the arrangement order of the categories and the arrangement order of the contents belonging to one category are determined in accordance with a predetermined criterion in the display device 1. Therefore, when there is an instruction to move between the page and / or the category from the user, the main body control unit 16 determines the content to be newly displayed with reference to the arrangement order, and displays the UI item 132 corresponding to the determined content. FIG. 6 is a diagram for further illustrating the movement of such pages and / or categories. The UI item 132 shown by the solid line in FIG. 6 represents the currently displayed page and category, and the UI item 132 shown by the dotted line represents virtually the previous or next page or the previous or next category. The reference numbers in the circles shown on the UI items 132 in each case indicate the arrangement order of pages or categories. For example, in the case of inter-page movement, the order of arrangement of " 21 ", "22 ", and" 23 " On the other hand, the UI menu 131 may further include information (139a and 139b) informing in advance what the next or previous category is.

The movement of the page and / or the category may be performed by the motion of the user using the touch input unit 21. [ 7 shows an example of the motion of the user instructing the movement of the page and / or the category using the touch input unit 21. As shown in Fig. 7 shows the movement of the user's finger 30 as the motion of the user, but the motion of the user is not limited thereto.

7, the user can move the finger in the up, down, left and right directions (see the arrows in FIG. 7 and 30a, 30b, 30c and 30d) while touching the contact surface 211 of the touch input unit 21 . The main body control unit 16 determines to move to the next or previous page or the next or previous category according to the direction of the user's motion on the contact surface 211 and switches the UI item 132 accordingly Can be displayed. In this embodiment, inter-category movement corresponds to the upper and lower motions (reference numerals 30c and 30d), and page-to-category movement corresponds to the left and right motions (reference numerals 30a and 30b) Liver movement can be accomplished, but this is only one example, and can take many forms. Therefore, according to the display device 1 of the embodiment of the present invention, a large number of contents can be retrieved more quickly and conveniently by an intuitive and simple operation using the touch input unit 21. [

The main body control unit 16 can determine the amount of movement of the page and / or category corresponding to the motion of the user on the contact surface 211 of the touch input unit 21. [ Specific factors for determining this amount of movement include, for example, the distance traveled by the user's motion on the contact surface 211 and its speed. 8 and 9 are diagrams for explaining the amount of movement of a page and / or a category corresponding to a movement distance and a speed of a motion, respectively. Similar to FIG. 6, in FIG. 8 and FIG. 9, the UI item 132 shown by the solid line represents the currently displayed page, and the two UI items 132 shown by the dotted line virtually represent the following pages. The reference numbers in the circles shown on the UI items in each case represent the arrangement order of the pages (in order of "1", "2", and "3"). In the embodiment of the present invention illustrated using Figs. 8 and 9, only the movement of the page is illustrated and explained, but it should be noted that the same can be applied to the category.

Referring to FIG. 8, two motions of moving the touch input unit 21 are displayed at the lower end. When both of the motions of the two cases are moved to the right (i.e., the corresponding UI item is moved to the next page) . Reference numerals 30e and 30f shown at the lower left of FIG. 8 denote the positions of the user's fingers corresponding to the start and end points of the motion when the motion is small, and reference numerals 30g and 30h, And the positions of the user's fingers corresponding to the start point and the completion point of the motion in the large case, respectively. That is, the former corresponds to a case where the moving distance of the motion is small, and the latter case corresponds to the case where the moving distance of the motion is large. The main body control section 16 can determine the amount of movement such that the movement of the page is relatively large when the movement distance of the motion is large as compared with the case where the movement distance of the motion is small. For example, in a state in which the UI item 132 of the page with the current arrangement order is "1 " is displayed and the movement distance of the motion is small, the main body control unit 16 sets UI items It is possible to switch to the UI item 132 of the page in the arrangement order "3 " arranged next to the arrangement order" 2 " .

As another example, referring to FIG. 9, similarly to FIG. 8, there are two types of motions for moving the touch input unit 21 at the lower end. In the case where both motions are moved in the right direction UI item is moved to the next page). Reference numerals 30i and 30j shown at the bottom left of FIG. 9 denote the positions of the user's fingers corresponding to the start and end points of the motion when the motion is slow, and reference numerals 30k and 30l, And the position of the user's finger corresponding to the start point and the completion point of the motion in the fast case, respectively. That is, the former corresponds to a case in which the speed of the motion is low, and the latter corresponds to the case in which the speed of the motion is high. The main body control section 16 can determine the amount of movement such that the page moves relatively more when the speed of motion is higher than when the speed of motion is low. For example, in the state where the UI item 132 of the page in which the current arrangement order is "1" is displayed, the main body control unit 16 sets the UI item of the page whose arrangement order is "2" 132, it is possible to switch to the UI item 132 of the page in the arrangement order "3 " arranged next to the arrangement order" 2 "

In any case, there is no particular limitation on the amount of movement of the page corresponding to one motion, and only one page may be moved or several pages more or less depending on the degree of motion of the user. Therefore, according to the display device 1 of the embodiment of the present invention, it is possible to search for a large number of contents more conveniently and quickly by only the intuitive and simple motion of the user on the touch input unit 21. [

10 and 11, a display device 1 according to another embodiment of the present invention will be described. 10 shows another example of the motion of the user instructing the movement of the page and / or the category by using the touch input unit 21. As shown in Fig. 10, the motion of the user indicating the movement of the page and / or the category is not limited to the up, down, left, and right directions, and also the diagonal direction is possible (the arrows 30m, 30n, 30p). If it is determined that there is a motion of the user in the diagonal direction, the main body control unit 16 can consider this as a combination of motion in the left and right direction and motion in the up and down direction, and determine the amount of movement of each of the corresponding page and category. For example, if the motion of the user is the diagonal direction of the upper right (see reference numeral 30n), the main body control section 16 can switch the UI item 132 to the next page and the previous category to display it. FIG. 11 is a diagram for explaining the movement of pages and / or categories corresponding to the motion of the user shown in FIG. 10; FIG. The UI item 132 shown by the solid line in FIG. 11 represents the currently displayed page and category, and the UI item 132 shown by the dotted line represents virtually the previous or next page or the previous or next category. The reference numbers in the circles shown on the UI items 132 in each case indicate the arrangement order of pages or categories. 11, "or " 13 "," 22 ", and "Quot; 31 "or" 33 ".

Hereinafter, a display device 1 according to still another embodiment of the present invention will be described. The display device 1 can provide a simple UI menu for searching for another channel while viewing any content (hereinafter also referred to as "channel"). 12 shows a simplified UI menu according to an embodiment of the present invention. 12, reference numeral 1311 denotes an image of a channel currently viewed, and reference numeral 1312 denotes a simplified UI menu for channel search. 12, the simple UI menu 1312 includes a plurality of UI items 1313, and each UI item 1313 shows channel information such as a channel name and a channel number. The plurality of UI items 1313 are arranged in a three-dimensional band shape, and the UI item 1313 corresponding to the channel currently being watched is positioned at the front.

The simple UI menu 1312 can start or cancel the display of the channel image 1311 if the user instructs it to view the channel image 1311. For example, when a touch like the one shown in FIG. 3 (a) is made through the touch input unit 21 during viewing of the channel image 1311, the display of the simplified UI menu 1312 can be started. In addition, if a touch of the same type as shown in FIG. 3A is again displayed during the display of the simple UI menu 1312, the display of the simplified UI menu 1312 can be canceled.

On the other hand, the plurality of UI items 1313 can be switched and displayed according to the user's instruction. For example, when switching to the downward direction, the current frontmost channel "781 " moves down one level and the channel" 412 " In this case, the background image 1311 may be changed to the channel "412 " at the same time. The switching of the channel may be performed according to a user's instruction using the key input unit 22 and the touch input unit 21. In particular, the main body control section 16 can determine the amount of movement of the plurality of UI items 1313 according to the motion of the user on the touch input section 21.

Since the contents described in the above embodiments can be similarly applied to the movement amounts of the plurality of UI items 1313 in this embodiment, a detailed description thereof will be omitted.

In addition, the channels appearing through the plurality of UI items 1313 can be classified into predetermined categories, and the categories can be switched and displayed according to a user's instruction. The simple UI menu 1312 can display information 1314 indicating the category to which the current channel belongs. The main body control unit 16 can switch the categories of the plurality of UI items 1313 according to the motion of the user on the touch input unit 21. [ In this case, the motion of the user can be left or right. The contents described in the above embodiment can be similarly applied to the conversion of the category of the plurality of UI items 1313 in this embodiment and the amount of movement thereof, and a detailed description thereof will be omitted. As described above, according to the display device 1 of the embodiment of the present invention, it is possible to search for another channel more conveniently and quickly during viewing by only intuitive and simple motion of the user on the touch input unit 21. [

13 to 15, a display device 1 according to still another embodiment of the present invention will be described. The display apparatus 1 can provide a channel information window for providing channel information during viewing of a channel image. 13 shows two examples of the channel information window 1315 according to an embodiment of the present invention. As shown in FIG. 13, the channel information window 1315 has a window shape and can be displayed in a superimposed manner on a partial area of the channel image 1311. The channel information window 1315 may include information on various channels such as information on other channels, viewing history, and the like.

The start and release of the display of the channel information window 1315 can be made according to the motion of the user on the touch input unit 21. [ FIG. 14 is a diagram for explaining the start of display of the channel information window 1315 according to an embodiment of the present invention. FIG. 15 is a diagram for explaining the cancellation of display of the channel information window 1315. FIG. Referring first to FIG. 14, the lower left end of FIG. 14 shows a user's motion on the touch input unit 21 to start displaying the channel information window 1315. FIG. Reference numerals 30q and 30r respectively denote positions of the user's fingers corresponding to the start and end points of the motion when the channel information window 1315 is displayed. In this case, as shown in the figure, it is shown that the user's finger moves as if it goes inward from the right edge 21a of the touch input unit 21. When it is determined that there is a motion of the user as shown at the lower left end of Fig. 14 during the viewing of the channel image 1311, the main body control section 16 sets the channel information window 1315 in the right side of the screen (See 1315a, 1315b and 1315c in Fig. 14).

Referring to FIG. 15, the lower left end of FIG. 15 shows the motion of the user on the touch input unit 21 for canceling the display of the channel information window 1315. FIG. Reference numerals 30s and 30t denote the positions of the user's fingers corresponding to the start and end points of the motion when the channel information window 1315 is released. In this case, as shown in the figure, the finger of the user moves from the inside to the right edge 21a of the touch input unit 21 as shown. When it is determined that there is a motion of the user as shown at the lower left end of Fig. 15 during the display of the channel information window 1315, the main body control section 16 displays the channel information window 1315 in the right side The display can be released as if it is escaped to the edge (see 1315d, 1315e and 1315f in Fig. 14).

In the above embodiment, the channel information window 1315 enters or exits from the right edge. However, the channel information window 1315 may be formed in various forms. As described above, according to the display device 1 of the embodiment of the present invention, the channel information can be more conveniently used only by intuitive and simple motion of the user on the touch input unit 21. [

Hereinafter, a control method of the display apparatus 1 according to an embodiment of the present invention will be described with reference to Figs. 16, the main body control unit 16 controls the video signal receiving unit 11 to receive the video signal of the channel selected by the user, and controls the display unit 11 based on the video signal received by the video signal receiving unit 11. [ And controls the image processing unit 12 so that the image is displayed on the display unit 13 (1601).

The main body control unit 16 determines whether there is a touch input of the user using the touch input unit 21 during the video viewing of the channel (1602). If there is no touch input by the user using the touch input unit 21 (No in 1602), the main body control unit 16 performs the operation 1601 again. On the other hand, when there is a user's touch input using the touch input unit 21 (Yes in 1602), the main body control unit 16 displays a UI menu (refer to reference numeral 131 in FIG. 5 or reference numeral 1312 in FIG. 12) (1603). The main body control unit 16 performs a channel search using the UI menu 131 or 1312 according to a user's instruction.

The main body control unit 16 confirms whether there is a touch input of the user using the touch input unit 21 during the display of the UI menu 131 or 1312 (1604). If there is no touch input by the user using the touch input unit 21 (No in 1604), the main body control unit 16 performs the operation 1603 again. On the other hand, if there is a touch input of the user using the touch input unit 21 (Yes in 1604), the main body control unit 16 cancels the display of the UI menu 131 or 1312 (1605). The main body control unit 16 confirms whether to continue the operation (1606). If the main body control unit 16 determines that the operation is to be continued (Yes at 1606), the main body control unit 16 returns to the operation 1601, otherwise ends the operation (No at 1606).

The control method of the display apparatus 1 will be described with reference to Fig. The display main body 10 displays a UI menu 131 or 1312 for channel search according to a user's instruction (1701). Meanwhile, the remote controller 20 senses the motion of the user on the touch input unit 21 (1702). The display main body 10 receives a remote control signal corresponding to the user's motion from the remote control device 20 (1703). Next, the display main body 10 determines the amount of movement of the page and / or the category of the UI item 132 or 1313 corresponding to the motion of the user, and displays the currently displayed UI item 132 or 1313 by the determined movement amount The UI item 132 or 1313 of the page and / or the moved category is displayed (1704).

Operation 1704 in Fig. 17 will be described in detail with reference to Fig. The main body control unit 16 analyzes the motion of the user and confirms the direction of the motion (1801). As a result of the operation 1801, when the direction of the motion is the left-right direction (Yes in 1802), the main body control unit 16 moves the page of the UI item 132 or 1313 by the amount of movement corresponding to the motion and displays the moved page. On the other hand, as a result of the operation 1801, when the direction of the motion is not the left-right direction (No of 1802) and the up and down direction (Yes of 1804), the main body control unit 16 displays the UI item 132 or 1313 by the movement amount corresponding to the motion, (1805). If the direction of the motion is neither the horizontal direction nor the vertical direction (No in 1804), the main body control unit 16 confirms whether to continue the operation (1806). If it is determined that the operation is to be continued (Yes in 1806) The operation returns to the operation 1801, otherwise (No in 1806), the operation is terminated. In the present embodiment, it is exemplified that only the left and right direction and the up and down direction are considered as the direction of the motion, but the present invention is not limited thereto, and the direction of the motion may be the diagonal direction as described with reference to Figs.

Another example of the control method of the display device 1 will be described with reference to Fig. The display device 1 displays an image based on a video signal of a channel selected by the user (1901). The display device 1 senses the touch input of the user using the touch input unit 21 during the display of the image (1902). As a result of the operation 1902, if the touch input is not a movement from the edge of the touch input section 21 inward (No of 1903), the operation 1901 is performed again. If the touch input is a movement from the edge of the touch input unit 21 to the inside (Yes in 1903), the display device 1 displays the channel information window 1315 as if entering the screen during the video display (1904).

The display device 1 senses the touch input of the user using the touch input unit 21 during the display of the channel information window 1315 (1905). As a result of the operation 1905, if the touch input is not the movement from the inside to the edge of the touch input unit 21 (No of 1906), the operation 1905 is performed again. If the touch input is from the inside to the edge of the touch input unit 21 (Yes in 1906), the display device 1 cancels the display of the displayed channel information window 1315 as if the displayed channel information window 1315 is out of the screen (1904). The display device 1 confirms whether the operation is to be continued (1908). If it is determined that the operation is to be continued (Yes in 1908), the display device 1 returns to the operation 1901, and otherwise (No in 1908), the operation is terminated.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
