Description

Display operation method and display device

The present invention relates to an operating method, and more particularly to a display operating method suitable for use in a display device. The present invention also relates to a display device having an OSD interface display function.

Most monitors on the market feature an OSD (On-Screen Display) interface. Often referred to as the "On-Screen Display" or "On-Screen Display Control Menu," the OSD primarily displays the monitor's configuration options, allowing users to adjust parameters such as brightness, contrast, and aspect ratio.

When users use display devices for different purposes, they often have different display requirements. For example, for work, users may want to lower the display brightness to avoid eye fatigue, while for entertainment, users may prefer to increase the display brightness and contrast to enhance the viewing experience.

Based on the above, how to make the OSD interface more user-friendly becomes a topic worth discussing.

Therefore, one of the objectives of the present invention is to provide a display operation method that can make the OSD interface more convenient to operate.

In the OSD mode, the processing unit controls the display unit to present the operation performed on the firmware through the input device according to at least one operation signal from the input device.

In some embodiments of the display operating method of the present invention, in step (A), in the operating system mode, the processing unit treats each operation signal from the input device as a system operation signal to be used to operate the operating system; in step (B), in the OSD mode, the processing unit treats each operation signal from the input device as a firmware operation signal to be used to operate the firmware, and the processing unit does not treat any operation signal as a system operation signal.

In some embodiments of the display operating method of the present invention, the display device further includes a prompt unit electrically connected to the processing unit. In step (A), when the cursor is located within the first display area, the processing unit further controls the prompt unit to output a first prompt notification corresponding to the first host device. When the cursor is located within the second display area, the processing unit further controls the prompt unit to output a second prompt notification corresponding to the second host device.

Another object of the present invention is to provide a display device that can make the OSD interface easier to operate.

The display device of the present invention is suitable for cooperating with an input device that can be operated by a user. The display device includes a processing unit suitable for being electrically connected to the input device, and a display unit electrically connected to the processing unit. The processing unit is used to: control the display unit to display a system interface based on an operating system, and the processing unit operates in an operating system mode, wherein, in the operating system mode, the processing unit controls the display unit to present the operation performed on the operating system through the input device in the system interface according to at least one operation signal from the input device; when the processing unit controls the display unit to display the system interface When an on-screen display (OSD) activation command is received in the case of a computer 24/7 operation, the display unit is controlled to display an OSD interface based on a firmware according to the on-screen display activation command, and the processing unit switches from the operating system mode to an OSD mode, wherein in the OSD mode, the processing unit controls the display unit to present the operation performed on the firmware through the input device according to at least one operation signal from the input device.

In some embodiments of the display device of the present invention, in the operating system mode, the processing unit treats each operation signal from the input device as a system operation signal to be used to operate the operating system. In the OSD mode, the processing unit treats each operation signal from the input device as a firmware operation signal to be used to operate the firmware, and the processing unit does not treat any operation signal as a system operation signal.

In some embodiments of the display device of the present invention, the display device further includes a storage unit electrically connected to the processing unit, and the firmware is stored in the storage unit. The processing unit is also adapted to be electrically connected to a host device, and the operating system is installed on the host device. In the operating system mode, the processing unit transmits each system operation signal to the host device, so that the host device performs operations based on the operating system according to the system operation signal. In the OSD mode, the processing unit does not transmit any operation signals to the host device.

In some embodiments of the display device of the present invention, the processing unit is adapted to be electrically connected to a first host device and a second host device. In the operating system mode, the processing unit controls the display unit to display two system interfaces simultaneously in a first display area and a second display area, respectively. The two system interfaces are based on two operating systems, and are respectively a first system interface displayed in the first display area and a second system interface displayed in the second display area. The two operating systems are respectively a first operating system installed on the first host device and including the first system interface, and a second operating system installed on the second host device and including the second system interface. The processing unit uses each operation signal from the input device as a signal to be used for operating the display. The processing unit further controls the display unit to display a cursor corresponding to the input device, and, when a cursor position corresponding to the cursor is located within the first display area, the processing unit uses the first host device as the transmission target of the system operation signal, and transmits the system operation signal to the first host device instead of to the second host device. When the cursor position is located within the second display area, the processing unit uses the second host device as the transmission target of the system operation signal, and transmits the system operation signal to the second host device instead of to the first host device.

In some embodiments of the display device of the present invention, the display device further includes a prompt unit electrically connected to the processing unit. When the cursor is located within the first display area, the processing unit controls the prompt unit to output a first prompt notification corresponding to the first host device. When the cursor is located within the second display area, the processing unit controls the prompt unit to output a second prompt notification corresponding to the second host device.

The utility of the present invention is that the display device allows users to use the same input device to operate the operating system through the system interface and the firmware through the OSD interface. This eliminates the need for users to operate hardware other than the input device in order to adjust settings through the OSD interface, making OSD interface operation more convenient.

Before the present invention is described in detail, it should be noted that, unless otherwise specified, the term "electrically connected" as used in this patent specification is used to describe the "coupled" relationship between computer hardware (e.g., electronic systems, devices, apparatuses, units, components), and generally refers to "wired electrical connections" achieved by physically connecting multiple computer hardware components through conductive/semiconductor materials, as well as "radio connections" achieved by wireless data transmission using wireless communication technologies (such as, but not limited to, wireless networks, Bluetooth, and electromagnetic induction). On the other hand, unless otherwise specified, the "electrical connection" described in this patent specification also generally refers to a "direct electrical connection" achieved by directly coupling multiple computer hardware components to each other, and an "indirect electrical connection" achieved by indirectly coupling multiple computer hardware components through other computer hardware components.

The term "unit" as used in this patent specification refers to computer hardware, not software. For example, a "processing unit" is used to represent computer hardware that performs data processing. On the other hand, a "unit" as used in this patent specification can refer to a single piece of computer hardware that performs a specific function, or a group of computer hardware that performs similar functions. For example, a "processing unit" can refer to a single processor that performs data processing, but it can also refer to a group of processors.

This patent specification provides multiple embodiments of the same invention. Therefore, in the following description, similar elements between different embodiments are represented by the same numbers.

1 , the present invention provides an embodiment of a display device 1 . In FIG1 , the embodiment is in a first application scenario, and in the first application scenario, the display device 1 is suitable for use with a host device 2 and an input device 3 .

The host device 2 is, for example, a desktop computer and includes a computer-readable storage medium (e.g., a hard drive, not specifically shown). Furthermore, an operating system 20 (OS) is installed on the computer-readable storage medium of the host device 2. The operating system 20 is a familiar operating system found in conventional desktop or laptop computers and will not be described in detail here.

The input device 3 is a USB human interface device (also known as a USB HID device) for manual user operation. For the purposes of this embodiment, it is assumed that the input device 3 in FIG1 is a mouse (which may be a wired or wireless mouse). However, in actual applications of this embodiment, the input device 3 may also be a drawing tablet, touchpad, or joystick. Therefore, the input device 3 applicable to this embodiment is not limited to a mouse. Furthermore, the display device 1 can actually be used in conjunction with multiple different input devices simultaneously. For example, in addition to the input device 3 in FIG1 (using a mouse as an example), the display device 1 can also be used in conjunction with a keyboard.

In this embodiment, the display device 1 is a screen device (eg, a desktop screen or a wall-mounted screen). The display device 1 includes a processing unit 11, a storage unit 12 electrically connected to the processing unit 11, a display unit 13, and a prompt unit 14.

In this embodiment, the processing unit 11 is a processor implemented as an integrated circuit and having data processing and instruction transmission and reception functions. Furthermore, the processing unit 11 is adapted to be electrically connected to the host device 2 and the input device 3. It should be noted that in this embodiment, the processing unit 11 utilizes, for example, HDMI (High Definition Multimedia Interface) and USB transmission standards to communicate with the host device 2, and utilizes USB transmission standards to communicate with the input device 3. However, it should be understood that in different embodiments, the processing unit 11 may utilize any commonly used transmission standard to communicate with the host device 2 and the input device 3, and is not limited to this embodiment.

In this embodiment, the storage unit 12 is a data storage medium (such as, but not limited to, a flash memory or EEPROM) for storing digital data. The storage unit 12 stores a firmware F, which includes a plurality of configuration parameters. The values of these configuration parameters are used to specify the display mode of the display device 1. Specifically, these configuration parameters may include a brightness configuration parameter for setting display brightness, a contrast configuration parameter for setting display contrast, and a color temperature configuration parameter for setting color temperature. It should be noted that the firmware F can be implemented using display firmware in the prior art, and its content can be freely designed and adjusted according to the actual function of the display device 1, so its details are not described in detail here.

In this embodiment, the display unit 13 is a display panel module, that is, the portion of the display device 1 used to display images. More specifically, the display unit 13 can be implemented as an LCD panel or an LED panel, but is not limited thereto.

In this embodiment, the prompt unit 14 comprises, for example, a plurality of light-emitting elements that can be controlled by the processing unit 11 to emit light. However, in other embodiments, the prompt unit 14 can also be implemented as a sub-screen independent of the display unit 13. Specifically, any hardware capable of outputting visual prompts under the control of the processing unit 11 is a feasible embodiment of the prompt unit 14.

It should be noted that, in similar implementations, the processing unit 11 may also be a circuit assembly including a processor and a circuit board, or a collection of multiple processors. The storage unit 12 may also be a collection of multiple storage media of the same or different types. Furthermore, in other implementations, the display device 1 may also be implemented as, for example, a head-mounted display device 1, or other computer hardware devices or equipment with display functions. Therefore, it should be understood that, whether it is the display device 1 as a whole, the processing unit 11, the storage unit 12, the display unit 13 or the prompt unit 14, its actual implementation in terms of computer hardware is not limited to this embodiment.

1 , 2 , and 3 , the following exemplarily illustrates how the display device 1 of this embodiment implements a display operation method in the environment of the first application scenario (ie, the environment of FIG. 1 ).

First, in step S11, the processing unit 11 controls the display unit 13 to display a system interface 201 (illustrated in FIG. 3 ) based on the operating system 20 based on the graphical data received from the host device 2. Furthermore, the processing unit 11 operates in an operating system mode. The system interface 201 is a graphical user interface (GUI) included in the operating system 20. Furthermore, when the processing unit 11 operates in the operating system mode, it allows a user to operate the operating system 20 via the system interface 201 using the input device 3.

More specifically, in the first application scenario of this embodiment, the graphical data indicates the content to be displayed by the display unit 13 and is generated, for example, by a graphics processor (GPU) (not shown) included in the host device 2. Furthermore, the graphics processor of the host device 2 transmits the graphical data to the processing unit 11 using, for example, the HDMI transmission standard. Furthermore, since the input device 3 in the first application scenario of this embodiment is a mouse, the processing unit 11 controls the display unit 13 to display a cursor 30 corresponding to the input device 3. The position of the cursor 30 displayed on the display unit 13 moves accordingly as the input device 3 moves.

When the processing unit 11 operates in the operating system mode and controls the display unit 13 to display the system interface 201, the process proceeds to step S12.

In step S12, when the processing unit 11 receives one or more operation signals from the input device 3 in the operating system mode, the processing unit 11 controls the display unit 13 to present the operations performed by the user on the operating system 20 through the input device 3 in the system interface 201 according to the (etc.) operation signal(s).

Specifically, each operation signal described in step S12 is generated by the input device 3 based on a user operation received by the input device 3, and the input device 3 transmits each operation signal to the processing unit 11 using the USB transmission standard. Since the input device 3 is a mouse in the first application scenario of this embodiment, each operation signal can, for example, indicate at least one of a movement operation, a left-click operation, a left-double-click operation, a left-drag operation, a right-click operation, a scroll wheel scroll operation, and a scroll wheel press operation received by the input device 3. When any operation signal indicates that the input device 3 is subjected to a moving operation, the operation signal actually indicates the displacement distance and direction of the input device 3. Thus, the processing unit 11 can calculate the current position of the cursor 30 in the display unit 13 (for example, presented as a two-dimensional coordinate) based on the displacement distance and direction indicated by the operation signal.

More specifically, when the processing unit 11 operates in the operating system mode, the processing unit 11 treats each operation signal from the input device 3 as a system operation signal to be used to operate the operating system 20, and transmits each system operation signal to the host device 2 using the USB transmission standard. Consequently, the host device 2 can operate the operating system 20 based on the system operation signal (the operation here is equivalent to the user's operation on the operating system 20 via the input device 3), generate graphic data indicating the operation results, and transmit the graphic data to the processing unit 11 using the HDMI transmission standard. In this way, the processing unit 11 can control the display unit 13 to present the operation results on the system interface 201 based on the graphic data from the host device 2. For example, the operation performed by the host device 2 based on the system operation signal may be moving the cursor 30, executing or closing a software program, opening or closing a folder or menu, selecting or removing files, or any other operation in the operating environment of the existing operating system.

When the processing unit 11 operates in the operating system mode and controls the display unit 13 to display the system interface 201, the process proceeds to step S13.

In step S13, when the processing unit 11 receives an on-screen display (OSD) activation command in the operating system mode, the processing unit 11 controls the display unit 13 to display an OSD interface 101 based on the firmware F according to the OSD activation command. Furthermore, the processing unit 11 switches from the operating system mode to an OSD mode. The OSD interface 101 is a graphical user interface included in the firmware F and includes a plurality of configuration options corresponding to the configuration parameters. It is worth mentioning that when the processing unit 11 operates in the OSD mode, its purpose is to allow the user to directly use the input device 3 to operate the firmware F through the OSD interface 101 without using other hardware other than the input device 3 (such as a remote control) to operate the firmware F.

In this embodiment, the on-screen display activation command comes from, for example, the input device 3. In other words, the user can directly operate the input device 3 to output the on-screen display activation command to the processing unit 11. This operation can be performed using a pre-set shortcut key (e.g., clicking the left button, clicking the right button, and then pressing the scroll wheel) to trigger the input device 3 to output the on-screen display activation command. Furthermore, as shown in FIG3 , in the OSD mode, the processing unit 11 controls the display unit 13 to display the OSD interface 101 on top of the system interface 201, such that the OSD interface 101 covers (obscures) a portion of the system interface 201, but this is not limiting.

When the processing unit 11 operates in the OSD mode and controls the display unit 13 to display the OSD interface 101, the process proceeds to step S14.

In step S14, when the processing unit 11 receives one or more other operation signals from the input device 3 in the OSD mode, the processing unit 11 controls the display unit 13 to present the operations performed by the user on the firmware F through the input device 3 according to the other (other) operation signals.

Specifically, each operation signal described in step S14 is also generated by the input device 3 according to the user operation received by the input device 3 and transmitted to the processing unit 11, and is similar to the operation signal(s) described in step S12.

More specifically, when the processing unit 11 operates in the OSD mode, the processing unit 11 interprets each operation signal from the input device 3 as a firmware operation signal for operating the firmware F. Based on the firmware operation signal, the processing unit 11 performs an operation on the firmware F (here, the operation is equivalent to an operation performed by a user on the firmware F via the input device 3), and controls the display unit 13 to present the result of the operation. Specifically, for example, the operation performed by the processing unit 11 based on the firmware operation signal may include changing the value of a setting parameter and adjusting the display mode of the display unit 13 in real time based on the value of the setting parameter (e.g., reducing the overall display brightness of the display unit 13). It should be understood that the operation performed by the processing unit 11 according to the firmware operation signal may also be other operations that can be implemented using the OSD mechanism of the prior art, and is not limited to the above-mentioned example.

It should be emphasized that in this embodiment, the processing unit 11 does not treat any operation signal from the input device 3 as a system operation signal when in the OSD mode. More specifically, when the processing unit 11 is operating in the OSD mode, the processing unit 11 does not transmit any operation signal from the input device 3 to the host device 2. This prevents the host device 2 from performing unintended operations when the user operates the firmware F.

When the processing unit 11 operates in the OSD mode and controls the display unit 13 to display the OSD interface 101, the process proceeds to step S15.

In step S15, when the processing unit 11 receives a command to terminate the on-screen display, it controls the display unit 13 to stop displaying the OSD interface 101 (i.e., closes the OSD interface 101) based on the command. Furthermore, the processing unit 11 switches from the OSD mode to the operating system mode. In this embodiment, the command to terminate the on-screen display may come from the input device 3, for example. In other words, the user may directly operate the input device 3 to input the command to the processing unit 11.

The above is an example of implementing the display operating method in the first application scenario according to this embodiment. By implementing the display operating method in the first application scenario according to this embodiment, the display device 1 allows the user to use the same input device 3 to operate the operating system 20 through the system interface 201, output the on-screen display start command to trigger the processing unit 11 to control the display unit 13 to display the OSD interface 101 and switch the processing unit 11 to the OSD mode, operate the firmware F through the OSD interface 101, and output the on-screen display end command to trigger the processing unit 11 to close the OSD interface 101 and switch back to the operating system mode. In this way, the user does not need to operate any hardware other than the input device 3 in order to adjust the setting parameters through the OSD interface 101, thereby making the operation more convenient.

Referring to FIG. 4 , a second application scenario of this embodiment is described below.

In the second application scenario of this embodiment, different from the first application scenario (please refer to FIG. 1 ), the display device 1 is used in conjunction with two host devices each having two operating systems installed thereon.

For ease of explanation, the two host devices in the second application scenario are referred to as a first host device 2A and a second host device 2B, respectively, as shown in FIG4 . The operating system installed in the first host device 2A is referred to as a first operating system 20A, and the operating system installed in the second host device 2B is referred to as a second operating system 20B. The first host device 2A and the host device 2 in FIG1 can be, but are not limited to, the same computer. In other words, the first operating system 20A and the operating system 20 in FIG1 can be the same operating system. Furthermore, it is assumed that the input device 3 in FIG4 and the input device 3 in FIG1 are the same mouse.

More specifically, in the second application scenario of this embodiment, the processing unit 11 is adapted to be electrically connected to the first host device 2A and the second host device 2B. Furthermore, the processing unit 11 can communicate with each of the first host device 2A and the second host device 2B using HDMI and USB transmission standards.

4 , 5 , and 6 , the following exemplifies how the display device 1 of this embodiment implements the display operation method in the environment of the second application scenario (i.e., the environment of FIG. 4 ).

First, in step S21, the processing unit 11 controls the display unit 13 to display a first system interface 201A based on the first operating system 20A and a second system interface 201B based on the second operating system 20B, as shown in FIG6 , based on the first graphic data received from the first host device 2A and the second graphic data received from the second host device 2B. Furthermore, the processing unit 11 operates in the operating system mode.

Specifically, the first system interface 201A is a graphical user interface (GUI) included in the first operating system 20A, and the second system interface 201B is a graphical user interface (GUI) included in the second operating system 20B. Furthermore, in the second application scenario of this embodiment, when the processing unit 11 operates in the operating system mode, it allows the user to use the input device 3 to operate the first operating system 20A via the first system interface 201A, and also to use the input device 3 to operate the second operating system 20B via the second system interface 201B.

More specifically, in the second application scenario of this embodiment, the processing unit 11 utilizes picture-in-picture (PiP) technology to control the display unit 13 to simultaneously display the first system interface 201A and the second system interface 201B in a first display area 130A and a second display area 130B, respectively. As shown in FIG6 , the first display area 130A and the second display area 130B are arranged side by side and have the same area in this embodiment. Furthermore, since the input device 3 is a mouse, the processing unit 11 also controls the display unit 13 to display the cursor 30 corresponding to the input device 3. It should be noted that the relative position and area size relationship between the first display area 130A and the second display area 130B can be freely set and adjusted according to needs, and is not limited to this embodiment.

In the second application scenario of this embodiment, the first and second graphic data both indicate content to be displayed by the display unit 13. The first graphic data is, for example, generated by the graphics processor of the first host device 2A and transmitted to the processing unit 11 by the graphics processor of the first host device 2A using the HDMI transmission standard. The second graphic data is, for example, generated by the graphics processor of the second host device 2B and transmitted to the processing unit 11 by the graphics processor of the second host device 2B using the HDMI transmission standard.

When the processing unit 11 operates in the operating system mode and controls the display unit 13 to display the first system interface 201A and the second system interface 201B, the process proceeds to step S22.

In step S22, when the processing unit 11 receives one or more operation signals from the input device 3 in the operating system mode, the processing unit 11 controls the display unit 13 to display, on one of the first system interface 201A and the second system interface 201B, the user's operation performed on the first operating system 20A or the second operating system 20B via the input device 3 based on the operation signal(s). Each operation signal is generated by the input device 3 based on a user operation received by the input device 3.

Specifically, in the operating system mode, the processing unit 11 treats each operation signal from the input device 3 as a system operation signal to be used to operate a single one of the first operating system 20A and the second operating system 20B, and transmits the system operation signal to a single corresponding one of the first host device 2A and the second host device 2B.

More specifically, when the processing unit 11 receives an operation signal from the input device 3, if the processing unit 11 determines that the cursor position corresponding to the cursor 30 is within the first display area 130A (i.e., the cursor 30 is located within the portion of the display unit 13 displaying the first system interface 201A), the processing unit 11 designates the first host device 2A as the destination for the system operation signal and transmits the system operation signal as a first system operation signal to the first host device 2A. Furthermore, in this situation, the processing unit 11 does not transmit any first system operation signal to the second host device 2B to avoid triggering the second host device 2B to perform an operation unintended by the user.

Conversely, if the processing unit 11 determines that the cursor is located within the second display area 130B (i.e., the cursor 30 is located within the portion of the display unit 13 displaying the second system interface 201B), the processing unit 11 designates the second host device 2B as the destination for the system operation signal and transmits the system operation signal as a second system operation signal to the second host device 2B. Furthermore, in this situation, the processing unit 11 does not transmit any second system operation signal to the first host device 2A to avoid triggering the first host device 2A to perform an operation not intended by the user.

In addition, in this embodiment, if the processing unit 11 determines that the cursor position is located within the first display area 130A, the processing unit 11 also controls the prompt unit 14 to continuously output a first prompt notification corresponding to the first host device 2A (for example, controlling one of the light-emitting elements of the prompt unit 14 to light up or flash), thereby prompting the user that currently only the first operating system 20A can be operated using the input device 3. Similarly, if the processing unit 11 determines that the cursor position is within the second display area 130B, the processing unit 11 also controls the prompt unit 14 to continuously output a second prompt notification corresponding to the second host device 2B (for example, controlling another light-emitting element of the prompt unit 14 to light up or flash), thereby reminding the user that currently only the second operating system 20B can be operated using the input device 3.

When the processing unit 11 operates in the operating system mode and controls the display unit 13 to display the first system interface 201A and the second system interface 201B, the process proceeds to step S23.

In step S23, when the processing unit 11 receives the on-screen display activation command in the operating system mode, the processing unit 11 controls the display unit 13 to display the OSD interface 101 (shown in FIG. 3 ) in accordance with the on-screen display activation command. Furthermore, the processing unit 11 switches from the operating system mode to the OSD mode. Since the operations of the processing unit 11 in step S23 are substantially the same as those in step S13, the details will not be repeated here. Furthermore, if the processing unit 11 is operating in the OSD mode and controls the display unit 13 to display the OSD interface 101, the process proceeds to step S24.

In step S24, when the processing unit 11 receives one or more additional operation signals from the input device 3 in the OSD mode, the processing unit 11 controls the display unit 13 to present the user's operations on the firmware F via the input device 3 based on the additional operation signal(s). Since the operation of the processing unit 11 in step S24 is substantially the same as that in step S14, the details will not be repeated here. Furthermore, if the processing unit 11 is operating in the OSD mode and also controls the display unit 13 to display the OSD interface 101, the process proceeds to step S25.

In step S25, when the processing unit 11 receives an on-screen display end instruction from the input device 3, the processing unit 11 controls the display unit 13 to stop displaying the OSD interface 101 according to the on-screen display end instruction, and the processing unit 11 also switches from the OSD mode to the operating system mode.

The above is an example of implementing the display operating method in the second application scenario according to this embodiment. By implementing the display operating method in the second application scenario according to this embodiment, the display device 1 allows the user to use the same input device 3 to operate the first operating system 20A and the second operating system 20B through the system interface 201, output the on-screen display start command to trigger the processing unit 11 to control the display unit 13 to display the OSD interface 101 and switch the processing unit 11 to the OSD mode, operate the firmware F through the OSD interface 101, and output the on-screen display end command to trigger the processing unit 11 to close the OSD interface 101 and switch back to the operating system mode. In this way, the user does not need to operate other hardware other than the input device 3 in order to operate different operating systems or adjust setting parameters through the OSD interface 101, so the operation is more convenient.

In another embodiment of the display device 1 of the present invention, referring to FIG1 , unlike the first application scenario of the aforementioned embodiment, the operating system 20 can also be installed within the storage unit 12 of the display device 1 itself. This allows the display device 1 to display a system interface 201 (shown in FIG3 ) based on the operating system 20 for user operation, without requiring interaction with the host device 2 . In this embodiment, the display device 1 is equivalent to a built-in embedded single-board computer (SBC); in other words, the display device 1 itself is equivalent to an all-in-one computer.

It should be noted that steps S11 to S15, steps S21 to S25 and the flowcharts of FIG. 2 and FIG. 5 of this embodiment are merely used to illustrate one possible implementation of the display operation method of the present invention. It should be understood that even if steps S11 to S15 and steps S21 to S25 are combined, split, or reordered, if the resulting process achieves substantially the same effect as in the present embodiment in substantially the same manner, they still fall within the applicable aspects of the display operating method of the present invention. Therefore, steps S11 to S15 and steps S21 to S25 of the present embodiment and the flowcharts of Figures 2 and 5 are not intended to limit the applicable scope of the present invention.

In summary, by implementing the display operating method, the display device 1 allows the user to use the same input device 3 to operate the operating system 20 via the system interface 201 and to operate the firmware F via the OSD interface 101. This eliminates the need for the user to operate hardware other than the input device 3 in order to adjust settings via the OSD interface 101, making the operation of the OSD interface 101 more convenient and effectively achieving the purpose of the present invention.

However, the above description is merely an example of the present invention and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made within the scope of the patent application and the contents of the patent specification of the present invention are still within the scope of the present patent.
