Please refer to FIG. 1 , which is 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 disposed 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 can also be a projector, and the touch function can be achieved through image processing technology. In addition, the size of the display module 110 is, for example, between 43 inches and 86 inches, but can also be larger, such as 98 inches.

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

In this embodiment, the partial image F11 covers the second region R2 of the first frame F1. In other words, both the first region R1 and the second region R2 are located in the same frame (eg, the first frame F1 ) of the same display device (eg, the display module 110 ).

As shown in FIG. 1 , the first region R1 is located outside the arm movement range A1 of the display surface 110s of the display module 110 , and the second region R2 is located in the arm movement 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 second region R2 by the user U1, the first region R1 performs the same operation. Therefore, even if the first area R1 is located outside the arm movable range area A1 of the display module 110 , the first area R1 can be operated by operating the second area R2 .

As shown in FIG. 1, the display module 110 displays the boundary line R11 of the first region R1 of the first frame F1, wherein the boundary line R11 is, for example, a solid line or a dashed line, and the boundary line R11 can be dynamically flashed or statically maintained in the same form . In one 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 is not changed, the controller 120 may hide the boundary line R11 of the first region R1. In the 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.

The controller 120 can track the moving position of the user U1, and move the second region 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 downward. 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 region R2 to a second position P2, wherein the second position P2 is adjacent to the first position The position P1 is convenient for the user U1 to operate the second area R2 nearby. In one embodiment, when the user U1 moves a distance in the direction D1, the controller 120 moves the second region R2 by the same distance in the direction D1 accordingly.

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 region R2 with multiple fingers (eg, two fingers), and then moves the multiple fingers simultaneously to the second position P2 as shown in FIG. 2 . After releasing the finger, the controller 120 moves the second region R2 to the region corresponding to the second position P2 accordingly. In this example, the location detector 130 may not be needed.
