[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0017] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0018] This application provides an all-in-one machine that supports display switching. Please refer to Figures 1 to 3 As shown, the all-in-one machine includes a shell, a display screen and a switching switch arranged on the shell, a controller, and a display input interface for detecting whether an external display signal is input. The controller is electrically connected to the display screen, the switching switch and the display input interface, respectively. The display screen is used to play and display video signals. When the display input interface detects that an external display signal is input, the controller switches between the all-in-one machine local display, input display and window same-screen display according to the display switching signal of the switching switch.

[0019] In the utility model, the switching switch is arranged on the housing of the integrated machine, so as to facilitate operation. The switching switch can be an existing press-type button or a touch-type button.

[0020] The controller is connected between the switch and the display screen. Each time the switch is pressed, the controller outputs a switching signal to the display screen. The display screen switches between the local display of the all-in-one machine, the input display and the window display on the same screen according to the switching signal.

[0021] When there is no switch other than the power-on reset function on the all-in-one machine, this application adds an additional physical switch as a switching switch, and detects whether the switching switch is pressed to cyclically switch between local display, input display, and window display on the same screen. For details, please refer to Figure 1 As shown, when the all-in-one machine is running, the controller controls the display screen to default to local display, that is, to display the local desktop. The display input interface detects whether there is an external display signal input. When no external display signal input is detected, the controller will shield the switching signal of the switching switch and disable the switching function. When an external display signal input is detected, the controller detects whether there is a switching signal of the switching switch, that is, detects whether the switching switch is pressed. When the switching switch is detected to be short pressed for the first time, the controller controls the display screen to switch from local display to input display to display the screen information of the external display signal; when the controller detects that the switching switch is short pressed again, the controller displays the screen information of the input interface in a window to realize the same-screen display; when the controller detects that the switching switch is short pressed for the third time, the controller controls the display screen to switch to the local desktop. Similarly, the cyclic switching of local display, input display, and window same-screen display is realized by short pressing the switching switch multiple times.

[0022] When the all-in-one machine is in use, when the display input interface signal is disconnected and then reconnected, when the controller detects that there is a signal input to the display input interface after reconnection, the pressing of the switch is defined as the first pressing. According to the above process, the local display, input display, and window display on the same screen are cyclically switched by short pressing the switch multiple times.

[0023] When the integrated machine has a switch other than the power-on reset function, the existing keys of the integrated machine can be combined in a multiplexing editing mode to realize the conversion between the original key function and the switch key function. Among them, the keys in the multiplexing editing mode do not include the power-on key, that is, any one of the switch switches is different from the power-on key. For example, please refer to Figure 2 As shown, when the shell is also provided with a first button and a second button for volume adjustment or brightness adjustment, the first button and the second button are combined in a multiplexing editing manner to realize the function of a switching switch. When the display input interface detects that an external display signal is input, the first button and the second button are short pressed at the same time, and the first button and the second button output the display switching signal to enter the display switching mode. When the first button and the second button are short pressed at the same time again, the first button and the second button exit the display switching mode. The display switching mode includes switching between the local display of the all-in-one machine, the input display, and the window on-screen display. In the display switching mode, when the first button is short pressed for the first time, the display screen switches to the input display, when the first button is short pressed for the second time, the display screen switches to the window on-screen display, and when the first button is short pressed for the third time, the display screen switches to the local display.

[0024] The specific principle is as follows: when the controller detects an external display signal input through the display input interface, when the key signal of the first key or the second key is detected, the controller controls the first key or the second key to perform its original volume adjustment or brightness adjustment function. When the controller detects an external display signal input through the display input interface, and detects that the first key and the second key are short pressed at the same time, the functions of the first key and the second key are switched to the functions of the switch, and when the first key and the second key are short pressed at the same time again, the first key and the second key are switched to the original volume adjustment or brightness adjustment function.

[0025] When the functions of the first button and the second button are switched to the functions of the switching switch, when the first button is short pressed for the first time, the controller controls the display screen to switch from local display to input display to display the screen information of the external display signal. When the first button is short pressed for the second time, the controller displays the screen information of the input interface in a window to realize same-screen display; when the controller detects that the switching switch is short pressed for the third time, the controller controls the display screen to switch to the local desktop, and so on, by short pressing the first button multiple times to realize the cyclic switching of local display, input display, and window same-screen display. In addition, in one embodiment of the utility model, when the functions of the first button and the second button are switched to the functions of the switching switch, the second button can be set to a cycle mode opposite to the first button to make the operation more convenient.

[0026] During the use of the all-in-one machine, when the display input interface signal is disconnected and then reconnected, when the controller detects that there is a signal input to the display input interface after reconnection, the first button press is defined as the first press. According to the above process, the local display, input display, and window display on the same screen are cyclically switched by multiple short presses of the switch.

[0027] In one embodiment of the utility model, the display screen is a liquid crystal display screen. The utility model sets a switch on the housing of the all-in-one machine, and when the local display (local display) and the input display are switched, there is no need to run local software to display the input signal, and the local display, input display and window same-screen display of the all-in-one machine device can be quickly switched.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
