The present invention discloses a display device, a hardware plug-in connected to the display device, and a display device control method, especially a display device with a custom interface or a designated operating system interface, a hardware plug-in connected to the display device, and a display device Control Method.

With the rapid development of science and technology, various display systems are also widely used in daily life. For example, the projector can be connected to a computer to project the image of the computer onto the screen. The liquid crystal display can be connected to an audio-visual signal source (such as an optical disc drive) to provide users with various multimedia experiences. The current display system also provides various image parameters for users to set. For example, a liquid crystal display can use a built-in processor (such as a Scaler) to execute an on-screen display (OSD) function to provide a graphical user interface (GUI).

In a more advanced display system, the display system can support the external function of a hardware plug-in (Hardware Dongle). For example, when the hardware plug-in is connected to the liquid crystal display, the user can perform specific functions of the hardware plug-in, such as executing specific applications. However, for users, even if the hardware plug-in is connected to the LCD, the LCD still only displays its built-in graphical user interface. The built-in graphical user interface can be regarded as a simplified and positive control interface for the function menu. Moreover, when a user operates a hardware plug-in to execute a special application, the hardware plug-in only provides an image source. In other words In other words, although the functions of the LCD display can be expanded through hardware plug-ins, the LCD display still only displays its built-in graphical user interface, so the built-in graphical user interface may be inconsistent with the extended functions. Therefore, users often cannot intuitively select the functions to be executed from the built-in graphical user interface, which causes inconvenience in operation.

In addition, traditional hardware plug-ins require external power supplies. For example, driving a hardware plug-in requires an additional Universal Serial Bus (USB) port or a DC converter. Since the hardware plug-in is connected to the LCD display, an external power supply is still needed, which causes inconvenience in operation.

FIG. 4 is a schematic diagram of the display system of FIG. 1 executing the display device control method.

FIG. 1 is a block diagram of an embodiment of the display system 100 of the present invention. The display system 100 includes a display device 10 and a hardware plug-in 11. The display device 10 is connected to the hardware plug-in 11. The display system 100 of the present invention can be applied to any device with image display function. For example, the display device 10 in the display system 100 may be a projector, which has the ability to project an image UI onto a plane. Display device in display system 100 The device 10 can also be a liquid crystal display, a tablet computer, a notebook computer or any kind of display. The hardware plug-in 11 is a portable (Portable) hardware device, such as a universal serial bus (USB) hardware plug-in or a high-definition multimedia interface (High-Definition Multimedia Interface, HDMI) hardware plug-in . The display device 10 includes a first processor 10a, a first memory 10b, and a connection port 10c. The first processor 10a can be any processing element, such as a scaler. The first memory 10b is coupled to the first processor 10a. The first memory body 10b stores a first interface. The first interface can be defined as a built-in interface of the display device 10 for adjusting various operating parameters. The connection port 10c is coupled to the first processor 10a. Port 10c can be any wired or wireless port, such as a universal serial bus (USB) port, a high-definition multimedia interface (HDMI) port, an infrared port, a Bluetooth wireless port, or wireless fidelity (W-Fi) port and so on. For a single display device 10 (the hardware plug-in 11 is not yet connected to the display device 10), the first processor 10a can control the display device 10 to display the first interface. The first interface can list at least one first operation option, such as control modes such as turning on, turning off, adjusting color contrast, adjusting image brightness, and so on. The user can control at least one first operation option through the first interface, so that the first processor 10a executes at least one first function. For example, the user can select a shutdown option through the first interface to control the first processor 10a to shut down the display device 10.

However, as mentioned above, the first interface is a built-in interface with relatively simple and positive functions. Therefore, the display system 100 can introduce the hardware plug-in 11 to generate a more advanced and optimized second interface, as described below. The hardware plug-in 11 includes a signal transceiver 11a and a second processor 11b. The second processor 11b is coupled to the signal transceiver terminal 11a. The second processor 11b can be any processing element, such as a microprocessor. The signal transmitting and receiving terminal 11a can correspond to the specifications of the connection port 10c of the display device 10. For example, when the connection port 10c is an HDMI port, the signal transceiver 11a may be a plug corresponding to the HDMI port. The hardware plug-in 11 may also include a second memory 11c. The second memory 11c is coupled to the second processor 11b. The second memory 11c can be used to install the operating system supporting the hardware plug-in 11 and the data of the second interface thereof, such as the data of the Android operating system and the Android interface. The second memory 11c can also store various applications under the operating system, such as applications YouTube. In the display system 100, the first processor 10a can establish a data connection with the signal transceiver 11a through the connection port 10c. After the data link is established, the second processor 11b can generate a second interface to the first processor 10a. The first processor 10a can generate a control signal through the second interface to perform at least one function. Moreover, the first interface of the display device 10 (such as a native built-in interface) is different from the second interface of the hardware plug-in 11 (such as a control interface under the Android operating system). The first processor 10a supports at least one first function, such as the aforementioned built-in functions such as turning on, turning off, adjusting color contrast, and adjusting screen brightness. The second processor 11b supports at least one second function, such as the function of executing various applications (YouTube, Netflix). After the data connection between the display device 10 and the hardware plug-in 11 is established, the first processor 10a can integrate at least one first function and at least one second function to display the second interface. In other words, the at least one first function can be regarded as at least one built-in function in the display device 10. The at least one second function may include at least one expandable application function corresponding to the operating system of the hardware plug-in 11. When the display device 10 displays the second interface, the user can freely control the built-in functions of the display device 10 and the application functions of the hardware plug-in 11. In other words, the second interface can be regarded as a customized interface with high operating convenience.

In the display system 100, the display device 10 may include a control panel 10d. The control panel 10d is coupled to the first processor 10a. The control panel 10d is used to input at least one second operation option corresponding to the second interface. Moreover, the display system 100 may also include a smart phone 12 or a remote control 13. The signal transceiver terminal 11a of the hardware plug-in 11 can receive the control data of the smart phone 12 or the remote control 13 through the wireless communication device 11d. The smart phone 12 or the remote control 13 can be used to remotely input at least one second operation option corresponding to the second interface. For example, when the wireless communication device 11d supports Bluetooth communication, the wireless communication device 11 can establish a connection with the smart phone 12. In addition, the control data of the smart phone 12 can be transmitted to the HDMI signal transceiver 11a through the wireless communication device 11d. The signal transceiver 11a then transmits the control data to the first processor 10a through the connection port 10c to control the display device. However, the display system 100 is not limited by the aforementioned control mode. For example, an application can be installed in the smart phone 12 to optimize operation efficiency. The smart phone 12 or the remote control 13 can also be directly wirelessly connected to the display device 10 to directly control the first processor 10a of the display device 10. Any reasonable technical or hardware changes belong to the scope of the present invention.

FIG. 2 is a schematic diagram of the first two-way communication between the display device 10 and the hardware plug-in 11 in the display system 100. In this description, in the display system 100 of the present invention, the display device 10 and the hardware plug-in 11 support a two-way communication function. In other words, the data link between the display device 10 and the hardware plug-in 11 can be used to transmit the video signal and control signal of the second interface, as described below. After the display device 10 is connected to the hardware plug-in 11, the display device 10 can generate a second interface (such as a control interface under the Android operating system). The second interface contains multiple second operation options. After the user selects at least one second operation option by any means such as the control panel 10d, the smart phone 12 or the remote control 13, the first processor 10a can transmit the control signal S1 corresponding to the at least one second operation option to the second Processor 11b. If the control signal corresponds to at least one second function, the second processor 11b performs at least one second function according to the control signal. For example, the user uses the second interface displayed on the display device 10 to choose to execute the video and audio playback function of the application YouTube. At this time, the first processor 10a generates a control signal S1 to request the second processor 10b to execute the application YouTube under the operating system (such as the Android operating system). Then, the second processor 10b can transmit the image data S2 of at least one second function (such as the video playback function of the application YouTube) to the first processor 10a. Therefore, the display device 10 can play the video of the application YouTube. In other words, in Figure 2, in addition to providing a more advanced and optimized second interface, the hardware plug-in 11 can also be regarded as a hardware with extended functions so that the display device 10 can perform additional functions. (Such as the video playback function of the app YouTube). Therefore, users can enjoy a more novel control interface experience and advanced application functions.

FIG. 3 is a schematic diagram of the second two-way communication between the display device 10 and the hardware plug-in 11 in the display system 100. In Figure 3, after the display device 10 is connected to the hardware plug-in 11, the display device 10 can generate a second interface (such as a control interface under the Android operating system). The second interface contains multiple second operations Options. After the user selects at least one second operation option by any method such as the control panel 10d, the smart phone 12, or the remote control 13, the first processor 10a can transmit the control signal S3 corresponding to the at least one second operation option to the second Processor 11b. As mentioned above, the display device 10 supports at least one first operation option of many first interfaces, such as built-in options such as turning on, turning off, adjusting color contrast, adjusting screen brightness, and so on. In addition, the second interface (such as the control interface under the Android operating system) includes at least one second operation option. However, the position, design pattern, operation method, or path of at least one first operation option of the first interface and at least one second operation option of the second interface may be different. Therefore, the first processor 10a can correspond at least one first operation option of the first interface to at least one second operation option of the second interface. For example, the built-in shutdown option of the first interface corresponds to the shutdown option of the second interface under the Android system. In Figure 3, if the control signal S3 of at least one second operation option corresponds to at least one first function, the second processor 10b can correspond the control signal to the operation code through the second interface, and send the command signal S4 to control the first function. A processor 10a executes at least one first function corresponding to the control code. For example, if the user selects the first operation option of adjusting the color tone in the second interface. Since adjusting the color tone is a built-in function of the display device 10, there is a corresponding operation code (Control Code). Therefore, the second processor 10b that generates the second interface will issue a command signal S4 to control the first processor 10a to execute the function of “adjusting color tone” in the second interface. Subsequently, the first processor 10a can adjust the image tone according to the operation code for adjusting the tone. In other words, in Figure 3, the hardware plug-in 11 can provide a more advanced and optimized second interface. Even if the user chooses to execute the built-in function (the first function) of the display device 10, the user can enjoy a more novel control interface experience.

In addition to the aforementioned operation modes, the display system 100 can also optimize the built-in interface content in an automated manner. For example, the first processor 10a in the display device 10 can detect the stability of the hardware plug-in 11 on the port 10c of the display device 10 when the hardware plug-in 11 is inserted into the port 10c. If the hardware plug-in 11 is stably connected to the port 10c, the first processor 10a can automatically adjust the format or content data in the first interface, and further correspond at least one first operation option of the first interface to the second interface. The ultimate in interface One less second operation option. In other words, after the format or content data in the first interface is adjusted, the first processor 10a can communicate with the second processor 11b to convert the first interface to the second interface. Finally, the display device 10 can automatically display the second interface. For example, the information on the second interface can be presented with a relatively novel pop-up message, so that the user can enjoy a novel control interface experience. Moreover, the hardware plug-in 11 can be driven without an external power supply. In other words, after the hardware plug-in 11 is inserted into the connection port 10c, the hardware plug-in 11 can be directly driven by the power provided by the connection port 10c. Since the hardware plug-in 11 does not require an additional power supply port, the user can activate the hardware plug-in 11 in a plug-and-play manner to automatically generate a second interface, thereby increasing the convenience of operation.

FIG. 4 is a schematic diagram of the display system 100 executing the display device control method. The display device control method includes steps S401 to S404. Any reasonable technical changes belong to the scope disclosed in the present invention. Steps S401 to S404 are described below.

Step S401: Establish a data link between the display device 10 and the hardware plug-in 11; Step S402: After the data link is established, the display device 10 generates a second interface through the hardware plug-in 11; Step S403: The display device 10 uses the second interface The interface generates a control signal; step S404: execute at least one function according to the control signal.

The details of steps S401 to S404 have been described in detail in the foregoing, so they will not be repeated here. In the display system 100, the display device 10 itself has a built-in first interface. The function of the first interface is relatively simple and positive. However, after the user connects the hardware plug-in 11 to the display device 10 through the connection port 11c, the display device 10 can automatically convert the first interface to the second interface and display the second interface. Since the second interface can be regarded as an advanced and optimized operating interface, users can enjoy a better interface experience.

In summary, the present invention describes a display system. The display device in the display system has a built-in first interface. However, the display device can automatically display a more advanced and optimized second interface through a hardware plug-in. Moreover, users can also switch back to the built-in first interface at any time. therefore, For users, in addition to enjoying a more novel control interface experience, they can also enjoy the convenience of operation.

The foregoing descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made in accordance with the scope of the patent application of the present invention shall fall within the scope of the present invention.
