Therefore, it does not affect the user's viewing of the enlarged information display area 35' at all.

Fig. 5 is a control flow diagram of a display capable of increasing the information display area according to a preferred embodiment of the present invention. Please refer to FIG. 5, taking the display 1 shown in FIG. 4 as an example, after the display 1 is turned on (step S501), the microcontroller 142 of the display 1 judges whether the video processor 141 has a video signal input from the computer 2 (step S502), And until it is judged that there is a video signal input from the computer 2, the display panel 11 is controlled to display the picture according to the video signal of the computer 2 received by the video processor 141, for example, the web browser application executed by the computer 2 is presented on the picture as shown in FIG. Window 3 screen of the program and window interfaces such as the tool bar 33 of window 3 are hidden (step S503 ). At this time, the touch module 12 of the display 1 is the same as the existing touch module, sensing whether there is a touch input (step S504), and generating a touch point signal to output to the computer 2 when the touch input is sensed. the motherboard 21 of the computer 2 to make the motherboard 21 of the computer 2 perform corresponding operations according to the touch point signal (step S505 ). When no touch input is sensed or a touch point signal output has been generated, the microcontroller 142 then determines whether a user commands the display 1 to enter the OSD touch mode by pressing the switch key 131 (step S506). Switch the key 131, then the display 1 enters the OSD touch mode (step S507), if the switch key 131 is not pressed, then return to step S503.

After the display 1 enters the OSD touch mode (step S507 ), the microcontroller 142 controls the video processor 141 to superimpose and display the OSD tool bar 36 on the screen displayed on the display panel 11 (step S508 ). At this time, although the touch module 12 of the display 1 still senses whether there is a touch input (step S509), it will transmit the generated touch point signal to the microcontroller 142 when the touch input is sensed (step S510 ). Determine whether the touch point of the user is in the option icon 362 of the OSD tool bar 36 by the microcontroller 142 (step S511), if the touch point is not in the option icon 362 of the OSD tool bar 36, it means an invalid touch input, Therefore return to step S509 and continue to monitor whether there is a touch input. If the touch point is in the OSD tool bar 36 option icon 362, it means that it is a valid touch input. The microcontroller 142 judges that the user has touched A certain option of the OSD toolbar 36, and according to the touched option, a hotkey signal is output to the mainboard 21 of the computer 2 through the control circuit board 122, so that the mainboard 21 of the computer 2 executes the corresponding function according to the hotkey signal (step S512). Then, the micro-controller 142 then determines whether there is a user ordering the display 1 to leave the OSD touch mode by pressing the switch key 131 (step S513). If the switch key 131 is pressed, it means that the user commands the display 1 to leave the OSD touch mode. The microcontroller 142 controls the video processor 141 to stop superimposing the OSD tool bar 36 on the screen displayed on the display panel 11, and controls the display 1 to leave the OSD touch mode and return to step S503 (step S514). , it means that it is still in the OSD touch mode, so return to step S508.

In the OSD touch mode, when the microcontroller 142 senses no-touch input, it starts timing and judges whether the no-touch input exceeds the preset time (step S515), if the no-touch input has not exceeded the preset time, then Return to step S509 to continue timing and monitor whether there is any touch input. If no touch input exceeds the preset time, stop timing and control the video processor 141 to stop superimposing the OSD tool bar 36 on the screen (step S516 ). Then, the micro-controller 142 then judges whether there is a touch input from the user (step S517). If there is a touch input, it means that the user intends to resume displaying the OSD tool bar 36, so it returns to step S508. If there is no touch input, Then return to step S516 to continue to stop displaying the OSD toolbar 36 .

In one embodiment, when entering the OSD touch mode, the microcontroller 142 first controls the video processor 141 to display the OSD tool bar corresponding to the first application program in the preset sequence on the screen displayed on the display panel 11, using Or press the switching key 131 every time to make the microcontroller 142 control to switch and display the OSD tool bar corresponding to the next application program on the screen according to the preset order. In other words, the user can switch between multiple Cycle through the OSD toolbars corresponding to different applications. In this way, the user can press the switching key 131 several times according to the running application displayed on the screen until the OSD toolbar corresponding to the running application is switched.

In another embodiment, when entering the OSD touch mode, the microcontroller 142 first controls the video processor 141 to superimpose and display the OSD function menu on the screen displayed on the display panel 11. When the corresponding OSD tool bar option of the application being executed displayed on the screen is selected, the video processor 141 is controlled to superimpose and display the selected OSD tool bar on the screen. In addition, the user can add, delete, move, and edit the OSD tool bar and the options of the OSD tool bar through the OSD function menu, wherein the options for editing the OSD tool bar include icons for editing options and corresponding hotkey signals.

In summary, the display of the present invention provides users with the ability to enter or leave the OSD touch mode through the switch key of the display. In the non-OSD touch mode, the touch module of the display will sense the The touch input is output to the computer to make the computer perform corresponding operations. In the OSD touch mode, the microcontroller of the display superimposes the OSD toolbar on the displayed screen, and the touch module passes the sensed touch input by Output to the computer and send to the microcontroller, and when the microcontroller judges that a certain option of the OSD tool bar is touched, a hotkey signal is generated according to the touched option to output to the computer through the touch module to make the computer execute the corresponding In this way, the effect of increasing the information display area can be achieved when the computer is used to execute the application program and hide the screen presented by the toolbar of its window. In addition, the OSD toolbar can be translucent so that it will not affect the user's viewing of the information display area, and the OSD toolbar can be hidden or stopped displaying when the OSD toolbar is not touched by the user within a preset time after the OSD toolbar is displayed. It does not affect the user viewing the information display area at all. Moreover, the display of the present invention can be directly applied to any computer without prior installation of additional software on the computer.

Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Anyone skilled in this art can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, this The scope of protection of the invention should be defined by the claims.
