FIG. 9C illustrates a keyboard provided with a plurality of keys and operable to provide user operation to generate corresponding user commands. Fig. 9D shows a mouse provided with a wheel and left and right buttons. Fig. 9E shows a handwriting input panel provided with a touch panel for receiving touch to generate user instructions. Fig. 9F shows a presentation pen provided with a laser emitter and a switching control key.

The image controller 11 is coupled to the touch display 10. The image controller can judge the input image source of the image. The image controller 11 can execute an application program corresponding to the input image source, and the image controller 11 operates the application program according to the coordinate information to control the input image source, so as to control the image displayed by the touch display 10. In general, the display system 1 can receive the laser signal LS sent by the external laser remote controller 13, so as to control the display operation of the display system 1.
In detail, the touch display 10 may be, for example, but not limited to, a touch display 10 having an optical touch function. In addition to the touch display 10 being used for displaying images, the touch display 10 further includes a touch screen (not shown in fig. 1). Therefore, the touch display 10 can receive the light signal to determine the touch operation of the user on the touch display 10 and the coordinate information of the touch operation. Further, the touch panel of the touch display 10 may also receive the laser signal LS emitted to the position P1 on the touch display 10 and provide the coordinate information of the position P1 to the image controller 11.
The image controller 11 is coupled to the touch display 10. The image controller 11 can control the touch display 10 to display an image.

In detail, referring to fig. 4A to 4C for details of the laser remote controller 13, fig. 4A is a schematic diagram of the laser remote controller 13 according to an embodiment of the present invention. In the laser remote controller 13 depicted in fig. 4A, it may include a laser transmitter 130, a laser receiver 131, a controller 132, a transmission interface 133, and a key 134. Laser transmitter 130 may emit laser signal LS.

In one embodiment, the display system 2 can integrate application programs of different input image sources through the keys of the laser remote controller 13 b. For example, referring to fig. 5, fig. 5 shows a table 500 of input control signals generated by the keys 134-1 to 134-6 of the laser remote controller 13b according to an embodiment of the present invention, wherein the table divides the operation into 7 modules, and the image controller calls according to the input source and the application program.

In detail, at a first time, the laser signal LS emitted from the laser remote control 13 may be directed to the position P1 as shown in fig. 7D, and at a second time after the first time, the laser signal LS emitted from the laser remote control 13 may be changed to be directed to the position P2 in fig. 7E. In this embodiment, the image displayed by the touch display 10 may be, for example, an image source from a computer device, and the position at which the laser signal LS is directed may be changed from the position P1 to the position P2 according to the user operation. Correspondingly, in step S21, the touch display 10 may provide corresponding coordinate information to the image controller 11 to reflect the change of the laser signal LS from the position P1 to the position P2. In step S22, the image controller 23 may determine the application program of the input image source.

Specifically, the laser remote controller 13 may have a laser ranging function, and the distance information between the laser remote controller 13 and the touch display 10 is calculated by receiving the laser signal LS reflected by the touch display 10.

In this way, in step S21, in addition to the touch display 10 providing the coordinate information to the image controller 11, the laser remote controller 13 may provide the distance information to the image controller 11 to indicate the change of the distance between the laser remote controller 13 and the touch display 10. Next, in step S22, the image controller 11 may determine an application corresponding to the input image source. Finally, in step S23, the image controller 11 may control the application program according to the laser signal LS, the coordinate information of the laser signal LS, the converted input control signal and the distance information. In this way, the image controller 11 can display the image according to the first magnification corresponding to the distance D1 with the position P1 irradiated by the laser signal LS as the center, and display the image according to the second magnification corresponding to the distance D2 with the position P2 irradiated by the laser signal LS as the center, thereby achieving the zooming operation of the image through the additional distance information.
In an embodiment, when the laser remote controller 13 adjusts the magnification of the displayed image with different distances, the laser remote controller 13 can also adjust the range of the displayed image, that is, when the laser remote controller 13 adjusts the magnification of the displayed image with changing the distance between the laser remote controller 13 and the touch display 10, the laser remote controller 13 can also change the position of the laser signal LS to the touch display 10. In this way, the image controller 11 can adjust the image displayed according to the change of the coordinate information, and the image controller 11 can adjust the magnification of the displayed image according to the change of the distance information, so that the touch display 10 can zoom according to the position of the laser signal LS directed to the touch display 10.
In one embodiment, the display system 2 may adjust all or part of the displayed image by the distance between the laser remote controller 13 and the touch display 10. For example, when the displayed image is a map image, the display system 2 can adjust the overall magnification of the map by changing the distance between the laser remote controller 13 and the touch display 10, so as to zoom the map. Alternatively, when the display image is a movie image including a subtitle, the display system 2 may adjust the size of the subtitle only according to the laser signal LS emitted to the subtitle and the distance between the laser remote controller 13 and the touch display 10.
In addition, among the various image operations illustrated in fig. 7A to 7G, the corresponding operation is not limited to be performed only when a specific key receives an instruction. For example, the display system 2 is not limited to performing the zoom operation only when the zoom key receives the user command. In one embodiment, when the display system 2 includes the remote controller 13a, for example, as shown in fig. 4B, and only has the buttons 134, the image controller 11 can execute the application program in step S22. In step S23, the application program and the user interface of the application program are operated according to the laser signal LS and the coordinate information, so as to control the input image source. In one embodiment, when the display system 2 includes a remote controller 13b, such as that shown in fig. 4C, and has the buttons 134-1 to 134-6, the image controller 11 can perform the zooming operation corresponding to the button 134-4 receiving the zooming user command when pressed.
In this way, the user can control the display system 2 by using the laser signal LS, and intuitively operate to control the image displayed by the touch display 10 under the condition of visual feedback. On the other hand, in some cases, the control direction of the user operation controller and the display direction of the display may deviate, which may cause inconvenience in operation of the whole system. For example, when a user uses a device such as a motion sensing remote controller or a mouse as the controller, the control direction of the user is not consistent with the direction of the display when the user is not facing the display, which causes inconvenience in operation. Therefore, the display system 2 can also provide an intuitive operation interface for users, thereby effectively improving the convenience and user experience of the display system and the display method.

In step S41, the touch display 10 may determine whether the laser signal LS is received, so as to perform step S42 when determining that the laser signal LS is received, and perform step S43 when determining that the laser signal LS is received. In step S42, when the touch display 10 receives the laser signal LS, the touch display 10 can instruct the image controller 11 to receive the laser signal LS and provide the coordinate information of the position to which the laser signal LS is directed. In step S43, when the touch display 10 does not receive the laser signal LS, the touch display 10 can instruct the image controller 11 that it does not receive the laser signal LS.

In step S51, the image controller 11 may determine whether the touch display 10 indicates that it receives the laser signal LS and the corresponding coordinate information. When the determination result of step S51 is yes, the operation flow may execute step S52. On the contrary, when the determination result of step S51 is no, the operation flow may repeatedly perform step S51 to determine whether the touch display 10 receives the laser signal LS. Next, in step S52, the image controller 11 may determine the input image sources of the images displayed on the touch display 10, and classify the images according to the input image sources of the displayed images. In one embodiment, when proceeding to step S52, the image controller 11 may further send a confirmation signal to the laser remote controller 13 in response to the touch display 10 receiving the indication of the laser signal LS. In step S53, the image controller 11 may determine an application corresponding to the input image source. In one embodiment, the image controller may determine the corresponding application program according to the classification of the input image source. In step S54, the image controller 11 can execute the application program and display the corresponding user interface according to the control of the laser signal LS. In step S55, the image controller 11 may determine whether an input control signal provided by the laser remote controller 13 is received. When the determination in step S55 is yes, the flow proceeds to step S56. When the determination in step S55 is no, the process returns to step S55 to determine whether the input control signal is received. In step S56, the image controller 11 can operate the user interface of the application program according to the laser signal LS, the coordinate information corresponding to the laser signal LS and the input control signal, and returns to step S54 after the completion.
