The display module is configured to display a first frame including a part image, wherein the part image is located in a first region of the first frame. The controller is configured on the display module and is configured to capture the part image of the first frame and displays the part image in a second region different from the first region. The controller responds to an operation for one of the first region and the second region, the same operation for the other of the first region and the second region is performed. ## Claims ### Claim 1 A screen operation method of a display system, comprises: capturing a part image of a first frame displayed on the display system, wherein the part image is located in a first region of the first frame; displaying the part image on a second region different from the first region; in response to an operation of the display system on one of the first region and the second region, performing the same operation on another of the first region and the second region; and displaying, by a display device, the first frame; wherein the first region is located outside a user's arm movement scope with respect to a display surface of the display device, and the second region is located inside the user's arm movement scope with respect to the display surface of the display device. ### Claim 2 (depends on 1) The screen operation method according to claim 1, further comprises: displaying, by a second display device, a second frame, wherein the part image is displayed on the second region of the second display device, and the second region movably covers a portion of the second frame. ### Claim 3 (depends on 2) The screen operation method according to claim 2, wherein the first display device and the second display device are connected in parallel. ### Claim 4 (depends on 1) The screen operation method according to claim 1 wherein the part image covers the second region of the first frame. ### Claim 5 (depends on 1) The screen operation method according to claim 1, further comprises: tracking a first position of a user; and moving the second region to a second position so that the second position is adjacent to the first position. ### Claim 6 (depends on 1) The screen operation method according to claim 1, further comprises: in response to a copy instruction, copying the part image of the second region to a third region different from the second region, wherein the operation on the part image of the third region does not reflect to the part image of second region. ### Claim 7 (depends on 1) The screen operation method according to claim 1, further comprises: in response to a scaling instruction, scaling size of the second region without changing range of the second region. ### Claim 8 (depends on 1) The screen operation method according to claim 1, further comprises: in response to a scaling instruction, scaling size of the first region without changing range of the first region. ### Claim 9 (depends on 1) The screen operation method according to claim 1, wherein step of performing the same operation on another of the first region and the second region comprises: in response to scaling for one of the first region and the second region, scaling another of the first region and the second region. ### Claim 10 (depends on 1) The screen operation method according to claim 1, wherein step of performing the same operation on another of the first region and the second region comprises: in response to scrolling for the part image in the second region, correspondingly continuously moving position of the first region. ### Claim 11 (depends on 1) The screen operation method according to claim 1, wherein step of performing the same operation on another of the first region and the second region comprises: in response to movement for the second region, correspondingly moving the first region. ### Claim 12 (depends on 1) The screen operation method according to claim 1, wherein step of performing the same operation on another of the first region and the second region comprises: displaying boundary lines of the first region of the first frame; and after a predetermined time elapses, hiding the boundary lines of the first region. ### Claim 13 (depends on 1) The screen operation method according to claim 1, wherein step of performing the same operation on another of the first region and the second region comprises: in response to editing for the part image of the first region, correspondingly editing the part image of the second region. ### Claim 14 A display system, comprises: a display module configured to display a first frame, wherein the first frame comprises a part image located in a first region of the first frame; a controller disposed on the display module and configured to capture the part image of the first frame and display the part image on a second region different from the first region; wherein in response to an operation for the display module on one of the first region and the second region, the controller is configured to perform the same operation on another of the first region and the second region; and wherein the display module comprises a display device configured to display the first frame; the first region is located outside a user's arm movement scope with respect to a display surface of the display device, and the second region is located inside the user's arm movement scope with respect to the display surface of the display device. ### Claim 15 (depends on 14) The display system according to claim 14, wherein display module further comprise a second display device, wherein the second display device is configured to display a second frame, and the second region movably covers a portion of the second frame and displays the part image. ### Claim 16 (depends on 15) The display system according to claim 15, wherein the first display device and the second display device are connected in parallel. ### Claim 17 (depends on 14) The display system according to claim 14, wherein the display module is one display device, and the first region and the second region are in the display device. ### Claim 18 A display system, comprises: a display module configured to display a first frame, wherein the first frame comprises a part image located in a first region of the first frame; a controller disposed on the display module and configured to capture the part image of the first frame and display the part image on a second region different from the first region; wherein in response to an operation for the display module on one of the first region and the second region, the controller is configured to perform the same operation on another of the first region and the second region; wherein the display module comprises a display device configured to display the first frame; the first region is located outside a user's arm movement scope with respect to a display surface of the display device, and the second region is located inside the user's arm movement scope with respect to the display surface of the display device; and in response to a copy instruction, copy the part image of the second region to a third region different from the second region, wherein the operation on the part image of the third region does not reflect to the part image of second region.
