For reference, the definitions and functions of the HSD 161, the ADI 162, the HSI 163, the HUD 164, and the CNI 165 have been briefly described in the background. In addition, it is merely illustrative that the aeronautical instrument devices such as HSD 161, ADI 162, HSI 163, HUD 164, and CNI 165 are integrated into one multi-function displayer 160. FIG. . That is, it is apparent to those skilled in the art that the multi-function display device 160 according to the embodiment of the present invention may include other aeronautical instrument devices.

HSD 161, ADI 162, HSI 163, HUD 164, and CNI 165 distribute respective corresponding aircraft instrument information and symbols. Aeronautical instrument information and symbols provided by the HSD 161, ADI 162, HSI 163, HUD 164, and CNI 165 are displayed at the display device 167 via respective corresponding viewports. Is displayed.

The controller 166 configures a layout between the plurality of viewports according to the input signal received from the display device 167. In this case, the controller 166 may configure a layout between the plurality of viewports according to various layout strategies by using parameters regarding reference position coordinates, height, and width of each viewport. This placement strategy can be programmed into the controller 166.

The controller 166 displays the aircraft instrument information and symbols provided by the HSD 161, the ADI 162, the HSI 163, the HUD 164, and the CNI 165 based on the layout between the plurality of viewports thus configured. Control the display device 167.

The display device 167 operates in a touch screen manner. By way of example, display device 167 may use other display technologies other than liquid crystal display (LCD) or light emitting polymer display (LPD) for touchscreen functionality. In addition, capacitive technology, resistive technology, infrared technology, surface acoustic wave technology, and the like are mainly used as touch sensing technology, but the present invention is not limited thereto.

The display device 167 converts a touch of the screen into an electrical signal. This electrical signal is provided as an input signal to the controller 166. The display apparatus 167 may be configured to correspond to the HSD 161, the ADI 162, the HSI 163, the HUD 164, and the CNI 165 based on the layout between the plurality of viewports configured in the controller 166. Place the viewport on one screen.

It is assumed that the screen of the display device 167 of the multi-function displayer 160 according to an embodiment of the present invention is a 20 x 8 inch screen. However, it will be apparent to those skilled in the art that the display apparatus 167 of the multi-function display device 160 according to the embodiment of the present invention can be configured in various sizes. The layout of a plurality of viewports disposed on the screen of the display device 167 will be described in detail with reference to FIGS. 2 to 8 below.

2 is a diagram illustrating an initial screen of a multi-function displayer according to an embodiment of the present invention.

2, first to fourth viewports V1 to V4 are disposed on an initial screen. The first viewport V1 is configured in size of 8 x 8 inches. The first viewport V1 is disposed on the left side of the initial screen. The first viewport V1 displays aeronautical instrument information and symbols provided by the HUD. An icon I11 for changing the size of the first viewport V1 and an icon I12 for changing the position of the first viewport V1 are displayed in the first viewport V1.

The second viewport V2 is configured 4 by 4 inches in size. The second viewport V2 is disposed at the upper center of the initial screen. The second viewport V2 displays aeronautical instrument information and symbols provided by the HSI. An icon I21 for changing the size of the second viewport V2 and an icon I22 for changing the position of the second viewport V2 are displayed in the second viewport V2.

The third viewport V3 is configured to be 4 x 4 inches in size. The third viewport V3 is disposed at the lower center of the initial screen. The third viewport V3 displays aeronautical instrument information and symbols provided by the ADI. An icon I31 for changing the size of the third viewport V3 and an icon I32 for changing the position of the third viewport V3 are displayed in the third viewport V3.

The fourth viewport V4 is sized 8 x 8 inches. The fourth viewport V4 is disposed on the right side of the initial screen. The fourth viewport V4 displays aeronautical instrument information and symbols provided by the HSD. An icon I41 for changing the size of the fourth viewport V4 and an icon I42 for changing the position of the fourth viewport V4 are displayed in the fourth viewport V4.

Here, the position where the icon for changing the size or position of each viewport is displayed is not limited to one place. However, in one embodiment, an icon for changing the size of each viewport may be displayed at the lower right of each viewport, and an icon for changing the position of each viewport is displayed at the upper right of each viewport. Can be.

 For reference, a layout between a plurality of viewports arranged on the initial screen may be configured differently. For example, two viewports having a size of 4 × 4 may be disposed at the upper left and lower left of the initial screen, respectively. In addition, two viewports having a size of 8 x 8 may be disposed at the center and the right side of the initial screen, respectively.

As another example, two viewports having a size of 4 × 4 may be disposed at the upper right and lower right sides of the initial screen, respectively. In addition, two viewports having a size of 8 × 8 may be disposed at the left and the center of the initial screen, respectively.

A portion of the screen of the display device displays respective corresponding toggle icons for calling up a plurality of hidden viewports that are not placed on the current screen. For example, the first toggle icon TI1 and the second toggle icon TI2 may be displayed on the lower left of the full screen. That is, the first toggle icon TI1 and the second toggle icon TI2 are overlaid on the first viewport V1.

Here, the toggle icon displayed on the full screen is not limited to two. Therefore, the toggle icon will be displayed as many as the number of hidden viewports that are not placed on the screen. Toggle icons and invocation of viewports that are not placed on the screen will be described in greater detail below with reference to FIGS. 6 to 8.

3 is a diagram illustrating an example in which the size of a viewport is changed on the screen of FIG. 2. Referring to FIG. 3, when the icon I21 for changing the size of the second viewport V2 is touched, the second viewport V2 is changed to an 8 × 8 inch size and disposed at the center of the screen. Accordingly, the layout between the plurality of viewports needs to be reconfigured so that a blank space does not appear on the entire screen of the display device.

For example, the first viewport V1 is sized 4 x 4 inches and disposed at the upper left of the screen. The third viewport V3 is disposed at the lower left side of the screen while maintaining the size of 4 x 4 inches. The size and position of the fourth viewport V4 are not changed. This is exemplary and the layout between the plurality of viewports may be differently reconfigured.

In general, the user will be provided with aeronautical instrument information, which is considered to be more important through an 8 x 8 inch viewport. On the other hand, the user will be provided with aeronautical instrument information, which is considered less important, through a 4 x 4 inch viewport.

For example, a user who thinks that aircraft information provided by HSI is more important may need to change the size of the second viewport on the initial screen. To do this, the user will touch an icon I21 for changing the size of the second viewport. At this time, the layout between the viewports around the second viewport whose size is changed is reconfigured so that a blank does not appear on the entire screen of the display device. This layout reconstruction is done according to the placement strategy programmed in the control unit 166 of FIG.

As described above, by touching an icon for changing the size of the viewport, the size of the viewport can be changed and the layout between the adjacent viewports can be easily reconfigured.

4 and 5 are views illustrating an example in which the position of the viewport is changed on the screen of FIG. 3. 4 and 5, when the icon I42 for changing the position of the fourth viewport V4 is touched and dragged over the second viewport V2, the second viewport V2 and the fourth viewport The position of V4 is changed.

If the two viewports are resized, the size of the two viewports will change. In addition, when the sizes of the two viewports are changed with each other, as described above, the layout between neighboring viewports should be reconfigured so that no gap occurs in the entire screen. The layout strategy for reconfiguring this layout is programmed in the control unit 166 of FIG. Equations 1 and 2 are part of an example pseudocode for the placement strategy for reconstruction of the layout.

Big () {

current_small = prev_Big;

current_Big = prev_small;

other_current_small.x = current_small.x;

}

Small () {

current_Big = prev_small;

current_small = prev_Big;

other_current_small.x = current_small.x;

}

Referring to Equations 1 and 2, it is assumed that there are large viewports and small viewports. At this time, the layout strategy for reconstructing the layout is divided into a case where the large sized viewport moves (Equation 1) and a small sized viewport moves (Equation 2). Equations 1 and 2 also define changes in the size and position of the viewports affected when the layout is reconstructed. The size and position of the viewport are cyclically changed by the layout strategy for reconstructing the layout.

As described above, by touching and dragging an icon for changing the position of the viewport onto another viewport, the position between the viewports may be changed and the layout between the viewports in the vicinity may be easily reconfigured.

6 and 7 exemplarily show how a hidden viewport is called on the screen of FIG. 2. Referring to FIG. 6, the fifth viewport V5 that is hidden when the first toggle icon TI1 is touched on the initial screen is called. The fifth viewport V5 called is 20 x 2 inches in size and appears at the bottom of the entire screen. In this case, the fifth viewport V5 overlaps with the viewports already arranged on the entire screen.

The fifth viewport V5 displays aeronautical instrument information and symbols provided by the CNI. An icon I51 for changing the size of the fifth viewport V5 and an icon I52 for changing the position of the fifth viewport V5 are displayed in the fifth viewport V5. An icon I51 for changing the size of the fifth viewport V5 may be displayed at the lower right of the fifth viewport V5. An icon I52 for changing the position of the fifth viewport V5 may be displayed on the upper right side of the fifth viewport V5.

Here, the fifth viewport V5 may be disposed at a position of another viewport. For example, referring to FIG. 7, the fifth viewport V5 may be disposed at a position of the third viewport V3. To this end, the icon I52 for changing the position of the fifth viewport V5 may be dragged and dropped onto the third viewport V3. In this case, the fifth viewport V5 is 4 × 4 inches in size and is disposed in place of the third viewport V3 at the lower center of the entire screen. As a result, the third viewport V3 does not appear on the screen. Instead, it will be displayed as a third toggle icon TI3 for calling the hidden third viewport V3 without being placed on the screen.

As described above, according to the multi-function display device according to the embodiment of the present invention, the viewport displaying the aircraft instrument information, which is considered to be less important for the user's convenience, may not be disposed on the entire screen. Instead, it may be displayed as a toggle icon corresponding thereto. In addition, as described above, when the toggle icon is touched, the corresponding viewport may be called again.

FIG. 8 is a diagram illustrating a view of calling a viewport for setting a user mode on the screen of FIG. 2. Here, the user mode refers to a layout between a plurality of viewports arranged on the entire screen configured according to the user's convenience.

Referring to FIG. 8, the sixth viewport V6 that is hidden when the second toggle icon TI2 is touched on the initial screen is called. The called sixth viewport V6 appears at the bottom of the entire screen in a size of 20 x 2 inches. In this case, the sixth viewport V6 overlaps with the viewports already disposed on the entire screen.

The sixth viewport V6 displays a plurality of setting buttons for setting a user mode. For example, the first to fourth setting buttons SB1 to SB4 may be sequentially displayed on the upper left side in the sixth viewport V6.

In addition, a sixth viewport V6 displays a selection button for selecting a user mode. As the number of stored user modes increases, the number of corresponding selection buttons will also increase. As an example, assume that two user modes are stored. Therefore, in the sixth viewport V6, the first selection button UB1 and the second selection button UB2 corresponding to each of the two user modes may be sequentially displayed at the lower left.

In this case, the first user mode may be selected by touching the first selection button UB1. Thus, the plurality of viewports will be placed in full screen according to the layout of the first user mode. Then, the second user mode may be selected by touching the second selection button UB2. Thus, the plurality of viewports will be placed in full screen according to the layout of the second user mode.

When the first setting button SB1 is touched, the configuration between the viewports currently arranged on the screen is stored as one user mode. In this case, a new selection button will be added and displayed in the sixth viewport V6.

When the second setting button SB2 is touched, a state in which the selected user mode can be deleted is changed. Thereafter, when the selection button corresponding to the user mode to be deleted is touched, the corresponding user mode is deleted. In this case, the selection button corresponding to the deleted user mode may not be displayed in the sixth viewport V6.

When the third setting button SB3 is touched, the configuration between the viewports currently arranged on the screen is initialized. That is, the current screen will be converted to the initial screen. On the other hand, when the 4 setting button SB4 is touched, all stored user modes are initialized.

According to the multi-function display device according to the embodiment of the present invention, the layout between the plurality of viewports may be reconfigured for the user's convenience in the same manner as described with reference to FIGS. 3 to 7. In addition, as described in FIG. 8, the reconfigured layout may be stored, deleted, and initialized as a user mode.
