DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Detailed features and advantages of the present invention are described in the following detailed description, to the extent that a person skilled in the art can understand the technical contents of the present disclosure and implement it accordingly. In addition, according to the disclosed specification, claims and drawings, a person skilled in the art can easily understand the objectives and advantages of the present disclosure. The following embodiments are intended to further explain the aspects of the present invention in detail, without limiting the scope of the present disclosure in any way.

[0011] Please refer to Fig. 1. Fig. 1 is a block diagram of a display device according to an embodiment of the present disclosure. The display device 1 according to this embodiment of the present disclosure is suitable for electrical connection with a host 2 and an external operation device 3. The host 2 may be, for example, a commercially available game console, and the external operation device 3 may be, for example, a joystick of a remote control corresponding to the commercially available game console.

[0012] The display device 1 includes an imaging unit 11 , a display controller 13 , an image receiving port 15 , a command output port 17 , and at least one computing device 19 .

[0013] The imaging unit 11 may be, for example, a liquid crystal display (LCD) or other types of displays having similar specifications and functions, although the present disclosure is not limited thereto.

[0014] The display controller 13 is electrically connected to the imaging unit 11, and the display controller 13 may be, for example, a scaler or other type of controller having similar specifications or functions, although the present disclosure is not limited thereto.

[0015] The image receiving port 15 is electrically connected to the display control device 13, and is configured to obtain image data from the host 2 and transmit the image data to the display control device 13. The display control device 13 controls the imaging unit 11 to display the image data according to a display setting. Note that the image receiving port 15 may be other types of receiving ports having similar specifications and functions, such as a high-definition multimedia interface (HDMI (registered trademark)) or a personal computer display port (PC DP), but the present disclosure is not limited thereto.

[0016] The command output port 17 is electrically connected to the host 2, and the command output port 17 may be, for example, a Universal Serial Bus (USB) connector or another type of connector having similar specifications or functions, although the present disclosure is not limited thereto.

[0017] At least one computing device 19 is electrically connected to the display control device 13 and the command output port 17. In one example, there is only one computing device 19 electrically connected to the external operation device 3, and the electrical connection between the computing device 19 and the external operation device 3 can be made by wire or wirelessly.

[0018] The at least one computing device 19 has a host operation mode and a display operation mode, the at least one computing device 19 is configured to receive a control command from the external operation device 3, the at least one computing device 19 sends a control command to the host 2 via the command output port 17 in the host operation mode, and the at least one computing device 19 sends a control command to the display control device 13 to adjust a display setting in the display operation mode.

[0019] Please refer to FIG. 1. The display device 1 of the embodiment of the present disclosure further includes a control center 16, which is electrically connected to the display control device 13. The control center 16 can drive the computing device 19 to update its firmware through an electrical connection with the computing device 19. Operation protocols of more brands and models of the external operation device 3 can be installed in the computing device 19 through firmware updates, and thus the computing device 19 can support and determine more brands and models of the external operation device 3 through the operation protocols. For example, the display device 1 before being shipped from the factory installs and supports the operation protocol of the external operation device 3 only when the external operation device 3 is a joystick of the game console "Xbox One" manufactured by Microsoft. However, by updating the protocol firmware of the joystick of the Xbox One (registered trademark), data of the game console "Play Station (registered trademark)" manufactured by Sony, a Japanese company, can be installed in the computing device 19. Therefore, when the display device 1 is electrically connected to a PS4 game console manufactured by Sony, a desired operation can be performed on the PS4 game console manufactured by Sony using the plugged-in game console (i.e., the external operation device 3).

[0020] In some other embodiments of the present disclosure, the display device 1 may omit the design of the control center 16.

[0030] The control center 16 stores software, and the control center 16 drives one of the computing devices 19a and 19b via the software to update the firmware.

[0031] The switching device 14 is electrically connected to the hub 12 and the command output port 17. The switching device 14 may be, for example, a USB switch. The switching device 14 switches to a corresponding USB signal source according to an indicated signal source, such as a USB signal source of the host 2 or a USB signal source of the host 2'.

Note that the command output port 17 may be, for example, a USB output connector or another type of connector having similar specifications and functions, but the present disclosure is not limited thereto.

[0033] Depending on whether image data is sent from the host 2 via the first image receiving port 151 or image data is sent from the host 2' via the second image receiving port 152, the display control device 13 transmits a control command to control the switching device 14 to switch to the signal source of the host 2 or the host 2'. Depending on the switching operation of the switching device 14, the arithmetic device 19a and the arithmetic device 19b are electrically connected to either the first command output port 171 or the second command output port 172 via the hub 12 and the switching device 14.

[0034] That is, when image data received by the display control device 13 is sent from the host 2 via the first image receiving port 151, the display control device 13 may control the switching device 14 to switch to the first command output port 171, and the arithmetic devices 19a and 19b may be electrically connected to the first command output port 171 via the hub 12 and the switching device 14.

[0035] The connector 10a is electrically connected to the arithmetic device 19a and the external operation device 3, in other words, the arithmetic device 19a is electrically connected to the external operation device 3 by wire via the connector 10a. Also, the connector 10b is electrically connected to the arithmetic device 19b and the external operation device 3', in other words, the arithmetic device 19b is connected to the external operation device 3' by wire via the connector 10b.

[0037] The arithmetic device 19a is electrically connected to the display control device 13, and is electrically connected to a first command output port 171 and a second command output port 172 via the hub 12 and the switching device 14. The arithmetic device 19a has a host operation mode and a display operation mode, and is configured to receive a control command from the external operation device 3. In the host operation mode, the arithmetic device 19a transmits a control command to the host 2 via the first command output port 171, and transmits a control command to the host 2' via the second command output port 172. In the display operation mode, the arithmetic device 19a sends a control command to the display control device 13 to adjust the display settings.

[0038] The computing device 19b is electrically connected to the display control device 13, and is electrically connected to the first command output port 171 and the second command output port 172 via the hub 12 and the switching device 14. The computing device 19b has a host operation mode and a display operation mode, and is configured to receive a control command from the external operation device 3'.

In the display operation mode, the computing device 19b transmits a control command to the display control device 13 to adjust the display settings.

[0039] The computing device 19a and computing device 19b shown in the embodiment of FIG. 2 may support and determine more brands and models of external operation devices, such as the external operation device 3 and the external operation device 3′, by updating firmware.

[0040] The present disclosure provides a method of operation of a display device such as the display device shown in FIG. 1, the method of operation includes the steps of: receiving a control command from an external operation device 3 by at least one computing device 19; transmitting a control command to a host 2 via a command output port 17 by at least one computing device 19 when the at least one computing device 19 is in a host operation mode; transmitting a control command to a display control device 13 by at least one computing device 19 to adjust a display setting when the at least one computing device 19 is in a display operation mode; acquiring image data from the host 2 via an image receiving port 15 and transmitting the image data to the display control device 13; and controlling the image capture unit 11 so that the display control device 13 displays the image data according to the display setting. The method of operation of the display device 1 according to the above embodiment further includes the steps of receiving a control command from an external operation device 3 by at least one computing device 19; and switching between a host operation mode and a display operation mode by at least one computing device 19 in response to the switching command.

[0041] The method of operation of the display device 1 shown in FIG. 1 is also applicable to the display device 1' shown in FIG. 2 and will not be described here for the sake of brevity, as the concepts are similar.

[0042] The implementation of the operating method of the display device 1 is specifically shown in Figures 3, 4A and 4B, where Figure 3 is a flowchart for switching the mode of the computing device, and Figures 4A and 4B are flowcharts for the computing device sending control commands depending on the current mode.

[0043] Please refer to FIG. 1 and FIG. 3. As shown in FIG. 3, the display device 1 is in the stage "Start". The image receiving port 15 is electrically connected to the host 2, and in this case, the host 2 may be, for example, a commercially available game console such as PS4, PS5, Xbox One, or Nintendo Switch (registered trademark). In step S1, the external operation device 3 is plugged in. The external operation device 3 is plugged into an input socket via a plug of an electric wire, and the socket corresponds to the arithmetic unit 19 of the display device 1, so that the display device 1 is electrically connected to the external operation device 3. Note that the external operation device 3 may be, for example, a joystick of a commercially available game console of various brands. In step S2, the model of the external operation device 3 is confirmed, and the host 2 is notified that the external operation device 3 is connected. Note that the arithmetic unit 19 stores protocols corresponding to external operation devices of various brands and models, so that the display device 1 may be configured to notify the host 2 that the corresponding external operation device 3 has been plugged into the display device 1 in correspondence with external operation devices 3 of various brands and models, in order to make it easier for the host 2 to perform operations corresponding to the external operation device 3.

[0044] In step S3, the computing device 19 is in the host operation mode. If the computing device 19 successfully determines the model of the external operation device 3, the computing device 19 defaults to the host operation mode. In step S4, the computing device 19 determines whether it receives a switching command from the external operation device 3. After the computing device 19 defaults to the host operation mode, if the computing device 19 receives a switching command from the external operation device 3 again, the computing device 19 may exit the host operation mode and switch to the display operation mode. Alternatively, if the computing device 19 does not receive a switching command from the external operation device 3, the computing device 19 is still in the host operation mode.

[0045] In step S5, the arithmetic device 19 is in the display operation mode. When the arithmetic device 19 is in the host operation mode and receives a switching command from the external operation device 3, the arithmetic device 19 switches from the host operation mode to the display operation mode. In step S6, it is determined whether the arithmetic device 19 has received a switching command from the external operation device 3. If the arithmetic device 19 is in the display operation mode and receives a control command from the external operation device 3, the arithmetic device 19 switches from the display operation mode to the host operation mode. Alternatively, if the arithmetic device 19 is in the display operation mode and does not receive a switching command from the external operation device 3, the arithmetic device 19 remains in the display operation mode.

[0046] The implementation of the method of operation of the display device 1 shown in Figure 1 can also be applied to the display device 1' shown in Figure 2. As the concepts are similar, further description will not be given here for the sake of brevity.

[0047] Please refer to FIG. 1, FIG. 4A, and FIG. 4B. FIG. 4A is a flowchart of a computing device sending a control command when the computing device is in a host operation mode according to an embodiment of the present disclosure, and FIG. 4B is a flowchart of a computing device sending a control command when the computing device is in a display operation mode according to an embodiment of the present disclosure. As shown in FIG. 4A, in step S31, the computing device 19 receives a control command from the external operation device 3. In step S32, the computing device 19 sends the control command to the host 2 via the command output port 17 when the computing device 19 is in the host operation mode.

[0048] When the computing device 19 is in the host operation mode, the computing device 19 will transmit the control commands received from the external operation device 3 to the host 2, and the external operation device 3 will directly control the operation of the host 2 while transmitting the control commands.

[0049] As shown in FIG. 4B, in step S52, when the calculation device 19 is in the display operation mode, the calculation device 19 sends a control command to the display control device 13 to adjust the display settings, in step S53, the image receiving port 15 acquires image data from the host 2 and sends it to the display control device 13, and in step S54, the display control device 13 controls the imaging unit 11 in accordance with the display settings to display the image data.

[0050] When the computing device 19 is in the display operation mode, the computing device 19 transmits a control command to the display control device 13, and the external operation device 3 controls the imaging unit 11 to display the image data transmitted from the host 2 to the display device 1 according to the display setting. Note that the order of steps S52 and S53 can be interchanged, but the present disclosure is not limited thereto.

[0051] The flow charts of Figures 4A and 4B are also applicable to the display device 1' shown in Figure 2 and will not be described here for the sake of brevity, as the concepts are similar.

[0052] Please refer to FIG. 2, FIG. 5A and FIG. 5B. FIG. 5A is a schematic diagram of image data displayed by the imaging unit when the arithmetic device is in the host operation mode, and FIG. 5B is a schematic diagram of image data displayed by the imaging unit when the arithmetic device is in the display operation mode. For example, the external operation device 3 and the external operation device 3' may be game joysticks of the same brand and model (such as Sony PS4), and the host 2 and the host 2' may be game consoles of different brands. The external operation device 3 is electrically connected by wire to the arithmetic device 19a included in the display device 1 through a connector 10a, and the external operation device 3' is electrically connected by wire to the arithmetic device 19b included in the display device 1 through a connector 10b. When the external operation device 3 and the external operation device 3' are inserted, the arithmetic devices 19a and 19b are in the host operation mode by default. By pressing a preset key combination on the external operation device 3, such as the key "LT", the key "LB" and the key "Up", the external operation device 3 sends a switch command to the computing device 19a, thereby instructing the computing device 19a to switch between the host operation mode and the display operation mode. Similarly, by pressing a preset key combination on the external operation device 3', such as pressing the keys "LT", "LB" and "Up", the external operation device 3' sends a switch command to the computing device 19b, thereby instructing the computing device 19b to switch between the host operation mode and the display operation mode.

[0053] When a user selects a host 2 to play a game and turns on the host 2, the host 2 transmits current image data "a" to the display control device 13 via the first image receiving port 151, and the display control device 13 confirms that the source of the current image data "a" is the first image receiving port 151, and can control and switch the switching device 14 so that the calculation device 19a and the calculation device 19b are electrically connected to the first command output port 171 via the hub 12 and the switching device 14.

[0054] When the arithmetic device 19a is in the host operation mode, the external operation device 3 can directly control the host 2 to start the game by sending a control command. When the arithmetic device 19b is in the host operation mode, the external operation device 3' can directly control the host 2 to start the game by sending a control command. The host 2 sends the current image data "a" to the display device 1 via the first image receiving port 151, and the display device 1 controls the imaging unit 11 to display the image data "a" as shown in FIG. 5A. When it is necessary to adjust the display settings during the game, the user simultaneously presses the keys "LT", "KB", and "Up" to switch the arithmetic device 19a and the arithmetic device 19b to the display operation mode, and the imaging unit 11 corresponding to the lower right of the image data "a" displays the display setting menu "b" as shown in FIG. 5B. The user can operate the display control device 13 by sending a control command using the arithmetic device 19a or the arithmetic device 19b, and cause the imaging unit 11 to generate the operation result. That is, the user can instantly adjust image data parameters such as brightness and contrast by operating the display setting menu "b" at the bottom right of the image data with the game joystick without having to move his / her body close to the display device and press a touch button, but these buttons arranged on the display device 1 are configured to adjust the display settings. Note that the user may also directly set the display settings using the game joystick held in his / her hand.

[0055] As described above, after adjusting the display settings, the user may press a preset key combination, such as the key "LT", the key "LB", and the key "Up" to switch the computing device 19a or the computing device 19b to the host operation mode in order to facilitate the subsequent processing of the game. In addition to pressing a preset key combination of a switching mode after adjusting the display settings in the display settings menu "b", the user may select "Exit" in the display settings menu "b" to close the display settings menu "b" at the lower right of the image data, so that the computing device 19a or the computing device 19b returns to the host operation mode. That is, the user may switch the computing device 19a or the computing device 19b from the display operation mode to the host operation mode by selecting "Exit" in the display settings menu "b".

[0056] In light of the above description, the present disclosure proposes a display device and an operation method of the display device. The at least one computing device can switch between a host operation mode and a display operation mode, so that when the at least one computing device is in the display operation mode, the at least one computing device transmits a control command received from an external operation device to a display control device to directly adjust the settings of the display screen. In this case, the user can directly set the parameters of the display screen using the external operation device while maintaining the distance between the user and the display device, without moving the body forward relative to the display device, thereby improving the user's experience and providing the user with real-time interaction with the display device.

[0057] Although the present disclosure is disclosed in the above embodiments, they are not intended to limit the present disclosure.All changes and modifications made without departing from the spirit and scope of the present disclosure shall be included in the scope of the present disclosure.The claims of the present disclosure can be referred to the appended claims.
