In some cases, some universal remote controllers still need to remain controllers of the original factory for pairing, so that even if a user uses the universal remote controller, the user is limited by a complicated pairing process, and the burden of storing each controller cannot be completely eliminated.
For example, fig. 9A to 9G illustrate a plurality of remote control key configurations corresponding to a plurality of image sources respectively. Fig. 9A shows a tv remote controller, which is provided with a power key, a video record key, a mute key, a number key, a channel switch key, a volume switch key, a return key, and a plurality of function menu keys. Fig. 9B shows a network streaming media remote controller, which is provided with a power button, a main menu case, a direction selection case, a control button, a return button, a volume control button, a set function button, and the like. FIG. 9C illustrates a keyboard having a plurality of keys and operable by a user to generate corresponding user commands. FIG. 9D shows a mouse with a scroll wheel and left and right buttons. FIG. 9E shows a handwriting input panel, which is provided with a touch panel for receiving touch to generate user commands. FIG. 9F shows a presentation pen with a laser transmitter and a switch control button.
Therefore, the user is burdened by the numerous remote controller configurations corresponding to different input image sources, and the prior art needs to be improved.

The touch display 10 can display an image. The touch display 10 can receive the laser signal LS at the position P1 and generate the coordinate information corresponding to the position P1. The image controller 11 is coupled to the touch display 10. The image controller can determine the input image source of the image. The image controller 11 may execute an application corresponding to the input image source, and the image controller 11 operates the application according to the coordinate information to control the input image source, so as to control the image displayed on the touch display 10. In general, the display system 1 can receive the laser signal LS from the external laser remote controller 13, and then control the display operation of the display system 1.
In detail, the touch display 10 can be, for example, but not limited to, a touch display 10 with an optical touch function. In addition to the touch display 10 being capable of displaying images, the touch display 10 further includes a touch panel (not shown in fig. 1). Therefore, the touch display 10 can receive the optical 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 can 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 may control the touch display 10 to display an image. In one embodiment, the video controller 11 may receive a plurality of video sources 12-1-12-m, and the video sources 12-1-12-m may be, for example, television video sources, streaming video sources, or one of Over The Top (OTT) video sources, Universal Serial Bus (USB) video sources, and High Definition Multimedia Interface (HDMI) video sources. The image controller 11 receives data provided by the image sources 12-1 to 12-m, performs image processing, and displays images of one or more of the image sources 12-1 to 12-m on the touch display 10 according to user selection or preset control. On the other hand, the image controller 11 may also receive the coordinate information of the position P1 provided by the touch display 10 when the laser signal LS is transmitted to the position P1 on the touch display 10. Accordingly, the image controller 11 can determine which of the image sources 12-1 to 12-m is the input image source according to the source of the image. The image controller 11 can select a corresponding application program according to the input image source and operate the application program according to the coordinate information to control the input image source.

Specifically, for the image source of the image displayed on the touch display 10, the image controller 11 can determine whether the laser signal LS is displayed on the touch display 10 according to the coordinate information, and determine the position to which the laser signal is emitted according to the coordinate information. Further, the image controller 11 can determine which of the image sources 12-1 to 12-m the input image source is according to the source of the image. The image controller 11 can select a corresponding application program to call out different control modules according to the input image source, and operate the application program according to the coordinate information to control the input image source.

In one embodiment, the buttons 134 can sense different user pressing pressures to generate corresponding user commands. In this way, the controller 132 can recognize the user commands with different pressing rules and generate the input control signal corresponding to the user commands accordingly.
In the embodiment shown in FIG. 4C, the laser remote control 13b is provided with keys 134-1 to 134-6.

In one embodiment, the display system 2 can integrate the applications of different input image sources through the keys of the laser remote controller 13 b. For example, referring to fig. 5, fig. 5 is a table 500 showing the generation of input control signals by the buttons 134-1 to 134-6 of the laser remote controller 13b according to the embodiment of the present invention, wherein the table divides the operation into 7 modules, and the image controller makes a call according to the input source and the application program. In general, the image controller 13b can integrate a plurality of remote controllers as shown in fig. 9A to 9G according to the content of the table 500, thereby effectively improving the convenience of the user in operation.
In detail, the buttons 134-1 through 134-6 are listed in columns of the table 500. The different modes of operation of keys 134-1 to 134-6 are exemplarily listed in the second row of table 500.

In the first time period shown in fig. 7F, the laser remote controller 13 can emit the laser signal LS at a distance D1, and in the second time period shown in fig. 7G, the laser remote controller 13 can be changed to emit the laser signal LS at a distance D2. As such, 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 also 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 video controller 11 determines the application corresponding to the input video source. Finally, in step S23, the image controller 11 can 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 at the first time with the position P1 to which the laser signal LS is directed as the center and according to the first magnification corresponding to the distance D1, and display the image at the second time with the position P2 to which the laser signal LS is directed as the center and according to the second magnification corresponding to the distance D2, thereby achieving the zoom 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 at different distances, the laser remote controller 13 may also adjust the range of the displayed image, that is, when the laser remote controller 13 adjusts the magnification of the displayed image by changing the distance between the laser remote controller 13 and the touch display 10, the laser remote controller 13 may also change the position of the laser signal LS emitted to the touch display 10. In this way, the image controller 11 can adjust the frame of the displayed image according to the change of the coordinate information, and the image controller 11 can also 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 emitted 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 display image is a map image, the display system 2 can adjust the magnification of the whole 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 subtitles, the display system 2 may adjust only the size of the subtitles in the movie image according to the laser signal LS emitted to the subtitles and along with the change of the distance between the laser remote controller 13 and the touch display 10.
In addition, the various image operations illustrated in fig. 7A to 7G are not limited to the corresponding operations that can be performed only when a specific key receives an instruction. For example, the display system 2 is not limited to performing the zooming operation only when the zooming key receives the user command. In one embodiment, when the display system 2 includes a remote controller 13a, such as the one shown in fig. 4B, and only has the key 134, the image controller 11 may execute the application program in step S22. In step S23, the application and the user interface of the application 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 the one shown in FIG. 4C, and has buttons 134-1 to 134-6, the image controller 11 can perform the zooming operation when the button 134-4 receives the zooming user command.
In this way, the user can control the display system 2 by using the laser signal LS, and intuitively operate the display system with visual feedback to control the image displayed on the touch display 10. On the other hand, in some use cases, the control direction of the user operating the controller and the display direction of the display may deviate, thereby causing inconvenience in operation of the whole system. For example, when the 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 screen in 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 the user, thereby effectively improving the convenience and the user experience of the display system and the display method.

In step S30, the operation flow of fig. 8A may be started when any one of the keys of the laser remote controller 13 or the power key is pressed. In step S31, the laser remote controller 13 may emit a laser signal LS. In step S32, the laser remote controller 13 may determine whether an acknowledgement (acknowledge) signal returned by the image controller 11 is received, wherein after receiving the indication of receiving the laser signal LS and providing the coordinate information from the touch display 10, the image controller 11 determines that the laser signal LS is emitted onto the screen of the touch display 10, and provides the acknowledge signal accordingly. When the determination of receiving the confirmation signal is yes, step S33 is executed. When the determination of receiving the confirmation signal is negative, step S34 is executed to stop emitting the laser signal LS. In step S33, the laser remote controller 13 can determine whether any key is pressed, and execute step S35 to send a corresponding input control signal when any key is pressed. And re-executes step S32 when not pressed to determine whether an acknowledgement signal is received.
Fig. 8B is an operation flow of the touch display 10 according to an embodiment of the invention. The operation flow illustrated in fig. 8B may be executed by the touch display 10 illustrated in fig. 1 or fig. 3. In step S40, the touch display 10 can be activated to start executing the operation flow. 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 emitted. In step S43, when the touch display 10 does not receive the laser signal LS, the touch display 10 may indicate to the image controller 11 that it does not receive the laser signal LS.
Fig. 8C is a flowchart illustrating an operation of the image controller 11 according to an embodiment of the invention. The operation flow illustrated in fig. 8C may be executed by the image controller 11 illustrated in fig. 1 or fig. 3. In step S50, the video controller 11 can be activated to start executing the operation flow. 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 in the step S51 is no, the operation flow may repeatedly execute the step S51 to determine whether the touch display 10 receives the laser signal LS. Next, in step S52, the image controller 11 determines the input image source of the image displayed on the touch display 10 and classifies the input image source according to the displayed image. In an embodiment, when the step S52 is entered, the image controller 11 may further send a confirmation signal to the laser remote controller 13 in response to the indication that the touch display 10 receives the laser signal LS. In step S53, the video controller 11 determines the application corresponding to the input video source. In one embodiment, the image controller may determine the corresponding application according to the classification of the input image source. In step S54, the image controller 11 executes the application program and displays the corresponding user interface according to the control of the laser signal LS. In step S55, the image controller 11 determines whether an input control signal provided by the laser remote controller 13 is received. When the determination of step S55 is yes, the flow proceeds to step S56. When the determination of step S55 is no, go back to step S55 to determine whether an 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 then returns to step S54.
In summary, the display system and the display method of the present invention can intuitively operate the touch display according to the laser signal, and effectively integrate the control of the plurality of image sources. Therefore, the display system and the display method can effectively eliminate the complex control signal matching process aiming at a plurality of image sources or the hardware burden brought by operating a plurality of controllers of a plurality of image sources. In addition, the key configuration of the laser remote controller and the application program of the image controller for judging the input image source can effectively integrate and uniformly control the key control of different image sources, and the operation convenience of the display system and the display method is improved.
