In order to have a better understanding of the above-mentioned and other aspects of the present invention, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

Please refer to FIG. 1, which shows a schematic diagram of a display system 100 according to an embodiment of the present invention. The display system 100 includes a display module 110 and a controller 120. The controller 120 can be configured inside or outside the display module 110 to control the screen operation function of the display module 110. In one embodiment, the display module 110 is, for example, a touch display device, such as an electronic whiteboard, and the display module 110 may also be a projector, which achieves a touch function through image processing technology. In addition, the size of the display module 110 is, for example, between 43 inches and 86 inches, but it can also be larger, such as 98 inches.

The display module 110 is used for displaying a first frame F1, the first frame F1 includes a partial image F11, and the partial image F11 is located in a first region R1 of the first frame F1. The controller 120 is used to capture a partial image F11 of the first frame F1 and display the partial image F11 in a second region R2 that is different from the first region R1. In response to an operation on one of the first area R1 and the second area R2, the controller 120 performs the same operation on the other of the first area R1 and the second area R2.

In this embodiment, the partial image F11 covers the second area R2 of the first frame F1. In other words, the first area R1 and the second area R2 are both located on the same screen (such as the first screen F1) of the same display device (such as the display module 110).

As shown in Figure 1, the first area R1 is located outside the user's arm range A1 on the display surface 110s of the display module 110, and the second area R2 is located at the arm range A1 of the display surface 110s of the display module 110 within. In this embodiment, since the controller 120 responds to the operation of the user U1 on the second area R2, it performs the same operation on the first area R1. Therefore, even if the first area R1 is located outside the arm movement area A1 of the display module 110, the first area R1 can be operated by operating the second area R2.

As shown in Figure 1, the display module 110 displays the boundary line R11 of the first area R1 of the first frame F1, wherein the boundary line R11 is, for example, a solid line or a dotted line, and the boundary line R11 can dynamically flash or maintain the same form statically . In an embodiment, after a predetermined time has elapsed, the controller 120 may hide the boundary line R11 of the first region R1. For example, within the predetermined time, if the size or position of the first region R1 does not change, the controller 120 may hide the boundary line R11 of the first region R1. In a case where the boundary line R11 of the first region R1 is hidden, when the size or position of the first region R1 is changed, the controller 120 may restore the display of the boundary line R11.

Please refer to FIG. 2, which shows a schematic diagram of another screen operation method of the display system 100 of FIG. 1. The controller 120 can track the moving position of the user U1, and move the second area R2 to the second position P2 corresponding to the first position P1 after the user U1 moves, so that the second position P2 is adjacent to the first position P1. For example, as shown in FIG. 2, the display system 100 further includes a position detector 130, which can be disposed on the upper part of the display module 110 to detect the position of the user U1 in the past. When the position detector 130 detects that the user U1 moves in a direction D1 to the first position P1, the controller 120 accordingly moves the second area R2 to a second position P2, where the second position P2 is adjacent to the first position P2. The position P1 is convenient for the user U1 to operate the second area R2 nearby. In one embodiment, the user U1 moves a distance in the direction D1, and the controller 120 accordingly moves the second area R2 in the direction D1 by the same distance.

In another embodiment, the user U1 can adjust the position of the second region R2 by touch. For example, the user U1 touches the partial image F11 in the second area R2 with multiple fingers (such as two fingers), and then moves the multiple fingers to the second position P2 as shown in FIG. 2 at the same time. After releasing the finger, the controller 120 moves the second area R2 to the area corresponding to the second position P2 accordingly. In this example, the position detector 130 may not be needed. In addition, the touch mode of the screen operation method of this embodiment is not limited by the above-mentioned multi-finger touch mode.

Please refer to FIG. 3, which shows a schematic diagram of another screen operation method of the display system 100 of FIG. 1. In response to the copy command, the controller 120 copies the partial image F11 in the second region R2 to a third region R3 that is different from the second region R2, wherein the operation on the partial image F11 in the third region R3 does not reflect to the second region R2 Partial image inside F11. For example, the user can edit the partial image F11 in the third region R3. Since there is no linkage relationship between the third region R3 and the second region R2, the edited partial image F11 does not reflect the content of the second region R2. In one embodiment, in response to a storage command from the user, the controller 120 stores the partial image F11 in the third region R3 as an image file (not shown).

In one embodiment, the aforementioned copy command is generated by, for example, long pressing (for example, 1 second to 3 seconds) the second area R2, and when waiting for the second area R2 to float on the screen, drag the floated second area R2 To the position of the third region R3 in FIG. 3, and then after releasing the floating second region R2, the controller 120 copies the partial image F11 in the second region R2 to the third region R3. In addition, the touch method of the screen operation method of this embodiment is not limited by the above touch method.

Please refer to FIG. 4, which shows a schematic diagram of another screen operation method of the display system 100 of FIG. 1. The controller 120 responds to a zoom command and zooms the size of the second region R2 without changing the range of the first region R1. The zoom command is generated, for example, as follows: the user touches a corner C1 of the second area R2 with a finger, and while waiting for the second area R2 to float, drags the floated second area R2 to the position C1' in Figure 4, and then After releasing the floating second region R2, the controller 120 reduces the size of the second region R2 to the second region R2' shown in FIG. 4, where the position C1' is a corner of the second region R2'. In addition, the touch method of the screen operation method of this embodiment is not limited by the above touch method.

As shown in Figure 4. In another embodiment, the zoom command is generated as follows: the user touches a corner C1 of the second region R2 with a finger, and when waiting for the second region R2 to float, drags the floating second region R2 outward, and then After releasing the floating second region R2, the controller 120 enlarges the size of the second region R2. In the embodiment, whether the size of the second region R2 is reduced or enlarged, the size of the first region R1 may not be changed.

In another embodiment, the controller 120 may respond to a zoom command to zoom the size of the first region R1 without changing the range of the second region R2. The method of generating the zoom command in this example is similar to the previous embodiment. For example, the user touches a corner of the first region R1 with a finger, and when waiting for the first region R1 to float, drags the floating first region R1 outward or inward. Then, after releasing the floating first area R1, the controller 120 enlarges or reduces the size of the first area R1. In the embodiment, whether the size of the first region R1 is reduced or enlarged, the size of the second region R2 may not be changed.

Please refer to FIG. 5, which shows a schematic diagram of another screen operation method of the display system 100 of FIG. 1. The controller 120 responds to the zooming of one of the first region R1 and the second region R2, and zooms the other of the first region R1 and the second region R2.

For example, the user long presses the second area R2 with multiple fingers (such as two fingers), waits for the second area R2 to rise, and then the multiple fingers simultaneously draw the distance between each other, and then after releasing the floating second area R2, the controller 120 reduces the size of the second region R2 to the second region R2' shown in FIG. 5 and at the same time correspondingly reduces the size of the first region R1 to the first region R1' shown in FIG. For another example, the user long presses the second area R2 with multiple fingers (such as two fingers), and when waiting for the second area R2 to float, the multiple fingers simultaneously extend the distance between each other, and then release the floating second area R2 to control The device 120 enlarges the size of the second area R2 and correspondingly enlarges the size of the first area R1. In an embodiment, the enlargement or reduction of one of the first region R1 and the second region R2 can be reflected (or linked) to the other of the first region R1 and the second region R2.

Please refer to FIG. 6, which shows a schematic diagram of another screen operation method of the display system 100 of FIG. 1. The controller 120 can respond to the editing of the partial image F11 in the first region R1, and correspondingly edit the partial image F11 in the second region R2. For example, one of multiple users can edit the partial image F11 in the first area R1 (as shown in Figure 6, the user tick below the image C), and the controller 120 can edit the image in the second area R2 accordingly. The partial image F11 (as shown in Figure 6, the controller 120 also correspondingly tick below the image C), so that the other one of the multiple users can change from the content of the partial image F11 in the second region R2 nearby Know the editing content of the partial image F11 in the first region R1.

In another embodiment, the controller 120 can respond to the editing of the partial image F11 in the second region R2, and correspondingly edit the partial image F11 in the first region R1. For example, one of the multiple users can edit the partial image F11 in the second area R2, and the controller 120 correspondingly edits the partial image F11 in the first area R1, so that the other of the multiple users can follow nearby The content change of the partial image F11 in the first region R1 learns the editing content of the partial image F11 in the second region R2.
