This means that the display device does not need to connect to an external host and can still connect to the Internet. In another embodiment of the present invention, the display device needs to be connected to an external host in order to connect to the Internet. These embodiments are described below.

  Hereinafter, a first embodiment of the present invention in which the display device has the ability to connect to the Internet will be discussed. FIG. 1 shows a functional block diagram of the first embodiment of the present invention. In the first embodiment of the present invention, a display device 100 such as a television can be connected to the Internet.

  As shown in FIG. 1, the display device 100 includes a command receiving module 110, a processing module 120, an on-screen display (OSD) module 130, a screen 140, and a network module 150.

  The command receiving module 110 receives a control command UC from a remote controller (not shown) of the display device 100, and the control command UC is generated by pressing a button on the remote controller.

  The OSD module 130 generates an image on the screen 140 in order to generate a control menu image. The control menu image is added to the image signal received by the display apparatus 100, so that both the control menu image and the received image signal can be displayed on the screen 140.

  The processing module 120 is connected to the command receiving module 110 and the OSD module 130 and controls the OSD module 130 according to the control command UC received by the command receiving module 110.

  The screen 140 displays an image signal DATA (such as website contents) and an image generated by the OSD module 130.

  The network module 150 performs network transmission / reception. In this embodiment, the network module 150 outputs image data DATA to the screen 140 by processing input data IN such as website contents.

  FIG. 2 is a flowchart of cursor control according to the first embodiment of the present invention, and FIGS. 3 to 6 are operation diagrams of images displayed on the screen 140 according to the first embodiment of the present invention. Show. The following description will be given with reference to FIGS.

  First, as Step 210, the user presses a predetermined button or a combination of a plurality of buttons on the remote controller, and transmits a first control command that causes the display apparatus 100 to enter the human machine interface. . For example, the user can input “000” by pressing the “0” button three times in succession using the remote controller to cause the display apparatus 100 to enter the human machine interface. In this embodiment, entering the human machine interface means entering the cursor control mode.

  Next, as step 220, in response to the first control command transmitted by the remote controller, the processing module 120 controls the OSD module 130 to display a plurality of first layer partial areas on the screen 140.

  FIG. 3 shows a schematic diagram of a display device 100 that has not yet entered the human machine interface. Here, the screen 140 of the display apparatus 100 displays an image signal DATA that is the original image 310 and a cursor 320. FIG. 4 shows a schematic diagram of the original image 310, the cursor 320, and the nine first layer partial areas 410-490.

  More precisely, the processing module 120 receives and analyzes control commands. When the first control command is received as a control command indicating that the display device enters the human machine interface, the processing module 120 displays four grid lines 405 on the screen 140 (two of which are oriented horizontally and the rest The OSD module 130 is controlled so as to define nine first layer partial areas 410 to 490. The OSD module 130 further displays nine reference symbols 407_1 to 407_9 in the first layer partial areas 410 to 490, respectively. In the present embodiment, the reference symbols 407_1 to 407_9 may be Arabic numerals 1 to 9, respectively, and these Arabic numerals 1 to 9 correspond to the Arabic numeral buttons 1 to 9 on the remote controller, and the first hierarchy. Partial regions 410 to 490 are represented. For example, the reference symbol 407_2 of the first hierarchical partial area 420 is the Arabic numeral “2”, which means that the first hierarchical partial area 420 is selected when the user presses the Arabic numeral button 2 on the remote controller. Means. In the default state, the cursor 320 is displayed in the first layer partial area 450.

  In addition, the display color of the grid lines 405 may be different from the display colors of the reference symbols 407_1 to 407_9 so that they can be conveniently identified. For example, the display color of the grid line 405 may be red, and the display color of the reference symbols 407_1 to 407_9 may be yellow. Note that the display color, the number of first layer partial areas, and the number of reference symbols in the above description are used as examples for description, and are not intended to limit the present invention.

  Next, at step 230, it is determined whether any one of the Arabic numeral buttons 1 to 9 is pressed. That is, it is determined whether or not the next control command (that is, the second control command) has been received. When the result of step 230 is NO, the method returns to step 220 to wait for the next control command. Step 240 is executed when the next control command is received.

  In step 240, the cursor is moved to the destination in response to the Arabic numeral button pressed by the user. Specifically, the processing module 120 analyzes which of the Arabic numeral buttons is pressed and identifies which of the first layer partial areas 410 to 490 is a desired area. Next, the cursor is moved to the inside of the selected first layer partial region among the first layer partial regions 410 to 490.

  Next, as step 250, the OSD module 130 displays a plurality of second layer partial areas inside one of the first layer partial areas 410 to 490 under the control of the processing module 120. Specifically, the processing module 120 controls the OSD module 130 to display nine second layer partial areas inside the corresponding first layer partial area in accordance with the pressed Arabic numeral button.

  Steps 240 and 250 will be described with reference to FIG. FIG. 5 shows a schematic diagram in which nine second layer partial areas are displayed on the screen 140. The case of pressing the Arabic numeral button “8” is taken as an example. When the Arabic numeral button “8” is pressed, the cursor 320 is moved to a desired first layer partial region 480, and second layer partial regions 510 to 590 are further displayed in the first layer partial region 480. The In addition, in order to allow convenient identification, the OSD module 130 further displays grid lines 505 (horizontal and vertical directions) and reference symbols 507_1 to 507_9 in the first layer partial area 480. The cursor 320 is set so as to be positioned inside the second layer partial area 550 as a default setting. That is, the user only has to press the Arabic numeral button “8”, and the cursor 320 is moved to the corresponding position (first layer partial region 480). Further, the OSD module 130 divides the selected partial area in preparation for the user's next instruction.

  In the present embodiment, in order to define a more accurate position, one of the second layer partial areas 510 to 590 can be selected and divided. For example, while the screen 140 displays the second hierarchical partial areas 510 to 590, the cursor 320 is moved to the second hierarchical partial area 570 when the Arabic numeral button “7” is pressed. As shown in FIG. 6, third layer partial areas 610 to 690, grid lines 605 (horizontal and vertical directions), and reference symbols 607 </ b> _ <b> 1 to 607_9 are displayed inside the second layer partial area 570.

  Further, when the cursor moves to a desired destination, the user presses another button (such as an Arabic numeral button “0”) on the remote controller to select a target object where the cursor is located. Event can be generated. That is, at this time, pressing the Arabic numeral button “0” on the remote controller is equivalent to clicking the left button on the mouse.

  Note that the first embodiment of the present invention is not limited to displaying only partial regions of three layers. By repeating the above steps, the first embodiment of the present invention displays more than three partial areas on the screen in order to display more partial areas even in a much smaller area. This makes it more convenient to move the cursor to a desired position (partial area) with good operating accuracy.

  Hereinafter, a second embodiment of the present invention in which the display device is connected to an external host will be discussed. FIG. 7 discloses a functional block diagram of a display apparatus according to the second embodiment of the present invention. In the second embodiment of the present invention, the display device 700 such as a television cannot connect to the Internet and receives the image signal DATA transmitted by the external host 780 such as a personal computer, for example, the content of the website. There is a need to.

  As shown in FIG. 7, a display apparatus 700 according to the second embodiment of the present invention includes a command receiving module 710, a processing module 720, an OSD module 730, a screen 740, an event generation module 760, and input / output (I / O) An interface 770 is provided. The command receiving module 710, the processing module 720, the OSD module 730, and the screen 740 may be the same as or similar to the command receiving module 110, the processing module 120, the OSD module 130, and the screen 140 in the first embodiment. In the present specification, detailed description thereof will be omitted.

  The event generation module 760 generates a cursor movement event and a cursor hitting event according to the control command triggered by the user, and then notifies the external host 780 via the I / O interface 770. Specifically, after the processing module 720 analyzes the control command UC received from the command receiving module 710, if the control command UC represents a cursor movement or a cursor hit, the processing module 720 displays the movement control signal and hitting. Each of the control signals is used to notify the event generation module 760 to generate a cursor movement event or a cursor hitting event, and the cursor movement event and the cursor hitting event are then sent to the external host via the I / O interface 770. 780.

  When the user desires to move the cursor, that is, when any of the Arabic numeral buttons “1” to “9” is pressed, the event generation module 760 generates a cursor movement event in response thereto. It is necessary to notify the external host 780.

  However, the resolution of the image signal DATA output from the external host 780 to the display device 700 may be different from the resolution of the screen 740. Here, it is assumed that the resolution of the screen 740 is 1920 × 1080 and the resolution of the image signal DATA is 800 × 600. Under such a condition, the event generation module 760 generates the image signal from the first coordinates (x1, y1) related to the selected partial area according to the resolution of the screen 740 of the display device 700 and the resolution of the image signal DATA. It is necessary to execute coordinate transformation for generating the second coordinates (x2, y2) corresponding to.

  According to the description of the embodiment described above, the selected partial area can be any partial area from the first hierarchical partial area to the second hierarchical partial area. More specifically, taking FIG. 5 as an example, the Arabic numeral button “8” is pressed, and the first coordinates (x1, y1) are the selected partial region, for example, the second layer portion. Since the cursor is located at the center position of the area 550, the cursor is shown at the center position of the second layer partial area 550. Further, the second coordinate (x2, y2) is obtained from the event generation module 760 using, for example, a lookup table or internal calculation.

  The relationship between the first coordinates (x1, y1) and the second coordinates (x2, y2) is as follows.

[Equation 1]
x2 / x1 = 800/1920
[Equation 2]
y2 / y1 = 600/1080

  Accordingly, when the display apparatus 700 enters the human machine interface, the external host 780 notifies the event generation module 760 about the resolution of the image signal DATA. On the other hand, the display apparatus 700 can directly analyze the image signal DATA to obtain the resolution of the image signal DATA. The event generation module 760 includes the second coordinates in the notification information of the cursor movement event and notifies the external host 780 of the second coordinate.

  When the user's control command is a cursor hit, the event generation module 760 needs to generate a cursor hitting event in response to this and notify the external host 780 of it. For example, in the above embodiment, when the Arabic numeral button “0” is pressed, this is regarded as a cursor hitting event, and the event generation module 760 generates a cursor hitting event in response to this, and the cursor It is necessary to notify the external host 780 of the hitting event.

  Further, the I / O interface 770 receives the image signal DATA transmitted by the external host 780, and this image signal DATA is displayed on the screen 740. Further, the I / O interface 770 transmits the cursor movement event and the cursor hitting event generated by the event generation module 760 to the external host 780, thereby causing the corresponding operation to be executed.

  In the second embodiment, the cursor movement / hit operation is the same as or similar to that in the first embodiment, and therefore the detailed description thereof will not be repeated herein.

  According to the cursor movement method and the display device using the same disclosed by the above-described embodiment of the present invention, when a user uses a display device such as a television to connect to the Internet, the response on the remote controller By pressing the arabic numeral button, the cursor movement / hit can be easily achieved, and its operation is very simple and intuitive. Thus, such an operation is consistent with people's long-standing practice of using a remote controller to control a television. Furthermore, the cursor movement method of the present invention can be applied to an ordinary television remote controller, and therefore, there is no need to purchase an extra wireless mouse and no extra cost is imposed.

  Although the present invention has been described with respect to what is presently considered to be the most practical and preferred embodiments, it should be understood that the invention need not be limited to the above-described embodiments. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims.
