Background Art

[0002] Currently, the firmware update operation of the display usually needs to be performed through the USB interface of the display. One method is that the user inserts a mobile storage device storing the updated version of the display firmware into the USB interface of the display, and then starts the firmware update process from the on-screen display (OSD) menu of the display. Another method is that the user connects an external computer to the USB interface of the display via a USB cable. After the external computer downloads the updated version of the firmware, the firmware update process is executed through the external computer with specific instructions. If the display does not have a reserved USB interface, the display can usually only be sent to the manufacturer's maintenance point for the engineers to perform the firmware update process, which causes inconvenience to the user and increases time and cost. Therefore, how to propose a solution to the above problem that allows users to update the firmware of the display by themselves has become a problem that today's displays need to solve.

For example, when the remote control device 300 is a mouse or a keyboard, the remote control device 300 is communicatively connected to the smart device 200 via a Bluetooth interface, an infrared transmission interface, or a USB interface. For example, when the remote control device 300 is a smart phone, the remote control device 300 communicates with the smart device 200 via a Bluetooth interface, an infrared transmission interface, a USB interface, or a wireless LAN interface. For example, when the remote control device 300 is a Bluetooth remote control, the remote control device 300 communicates with the smart device 200 via a Bluetooth interface. For example, when the remote control device 300 is an infrared remote control, the remote control device 300 communicates with the smart device 200 via an infrared transmission interface. For example, when the remote control device 300 is a Wi-Fi remote control, the remote control device 300 communicates with the smart device 200 via a wireless LAN interface.

[0029] like Figure 1 As shown, the connector 110 of the display 100 is physically connected to the connector 210 of the smart device 200, for example, the connector 210 is a male connector and is physically connected to the connector 110 which is a female connector by insertion, and for example, the connector 110 and the connector 210 are physically connected by cable interconnection. In some embodiments of the present invention, the connector 210 and the connector 110 both include a High Definition Multimedia Interface (HDMI) interface, but the present invention is not limited to this. In another embodiment of the present invention, the connector 210 and the connector 110 both include a Digital Video Interface (DisplayPort, DP) interface. In another embodiment of the present invention, the connector 210 and the connector 110 both include a Universal Serial Bus Type-C (USB-C) interface.

[0030] Figure 21 is a flow chart of a display setting method 1000 according to a first embodiment of the present invention, comprising steps S11 to S14. In step S11, the remote control device 300 transmits a setting instruction to the smart device 200 through a transmission interface. In step S12, the smart device 200 converts the setting instruction into a display setting instruction corresponding to the setting instruction. In step S13, the smart device 200 transmits the display setting instruction to the display 100. In step S14, the display 100 performs a setting action corresponding to the display setting instruction.

[0031] In the first embodiment of the present invention, in step S13, the connector 210 and the connector 110 both include HDMI interfaces, and the smart device 200 transmits the display setting instruction to the display 100 via the display data channel (DDC). Specifically, in step S13, the connector 210 and the connector 110 both include HDMI interfaces, and the smart device 200 transmits the display setting instruction to the display 100 via the display data channel (DDC) in accordance with the monitor control command set (MCCS) standard established by the Video Electronics Standards Association (VESA). In other words, the display setting instruction transmitted by the smart device 200 to the display 100 is an MCCS instruction. Specifically, in step S12, the smart device 200 converts the setting instruction into an MCCS instruction. Specifically, the embodiments of the present invention can actually support any function within various display control command set (MCCS) standard specifications, such as but not limited to adjusting color temperature, saturation, HUE, brightness, contrast, volume, etc. For details, please refer to the "VESA Monitor Control Command Set Standard" document of the VESA Association.

[0032] In the first embodiment of the present invention, in step S14, the display 100 adjusts the display parameters accordingly according to the display setting instruction. The above-mentioned adjusted display parameters are substantially the display parameters that can be adjusted through the on-screen display (OSD), for example, including but not limited to: adjusting brightness, adjusting contrast, adjusting volume, etc. In other words, the setting instruction transmitted by the remote control device 300 in step S11 involves adjusting the display parameters. Generally speaking, the key operation of adjusting the parameters of traditional displays is quite cumbersome, and many steps are required to adjust a display parameter through the OSD. In contrast, through the display setting method 1000 of the first embodiment of the present invention, the user can adjust the display parameters without using any hardware buttons or OSD on the display 100. On the other hand, through the display setting method 1000 of the first embodiment of the present invention, the display 100 does not need to make hardware buttons thereon, so as to reduce the production cost of the display 100.

[0033] Figure 3 1 is a detailed system module diagram of a corresponding system 10 of a display setting method according to some embodiments of the present invention. Figure 3 As shown, the smart device 200 includes a connector 210, an input / output interface controller 220, a processing circuit 230 and an output circuit 240.

The interface circuit 222 is used to enable the smart device 200 to communicate with the remote control device 300 and receive setting instructions from the remote control device 300. The processor 232 receives the control instruction from the interface circuit 222 and is used to convert the setting instruction into a display setting instruction. The processor 232 is also used to convert the digital audio and video content received by the smart device 200 through the Internet into audio and video data. The memory 234 is used to store data related to the smart device 200, such as the setting parameters and browsing history of the smart device 200. The memory 234 can also be used to store the display parameters (such as current brightness, current volume, current firmware version, etc.) read back by the smart device 200 from the display 100. The audio and video output interface circuit 242 is used to receive audio and video data from the processor 232 and output the audio and video data to the display 100. The MCCS instruction circuit 244 is used to receive display setting instructions from the processor 232 and transmit the display setting instructions to the display 100.

[0034] like Figure 3As shown, the display 100 includes an input circuit 120, a processing circuit 130, an on-screen display (OSD) circuit 140, an audio-visual processing circuit 150, and an output circuit 160.

The screen setting menu unit 142 is used to receive the display setting instruction processed by the processor 132 from the processor 132, and to adjust the display parameters of the display 100 accordingly according to the display setting instruction processed by the processor 132. The audio and video processor 152 is used to receive the audio and video data from the audio and video input interface circuit 122, and to process the audio and video data. The mixing circuit 154 is used to receive the adjusted display parameters from the screen setting menu unit 142, and to receive the processed audio and video data from the audio and video processor 152, and to mix the processed audio and video data and the adjusted display parameters. The audio and video output circuit 162 is used to receive the mixed audio and video data from the mixing circuit 154, so that the mixed audio and video data can be displayed on the display screen of the display 100 accordingly.

[0035] Figure 42 is a flow chart of a display setting method 2000 according to a second embodiment of the present invention, comprising steps S21 to S28. In step S21, the remote control device 300 transmits a setting instruction to the smart device 200 through a transmission interface, wherein the setting instruction in step S21 involves a firmware update of the display 100. In step S22, the smart device 200 reads the version information of the current version firmware of the display 100 from the display 100. In step S23, the smart device 200 determines whether there is an updated version firmware relative to the current version firmware, if so, proceeds to step S24, otherwise the process ends. In step S24, when the smart device 200 determines that there is an updated version firmware, the smart device 200 downloads the updated version firmware. In step S25, the smart device 200 converts the setting instruction into a display setting instruction corresponding to the firmware update. In step S26, the smart device 200 transmits the display setting instruction corresponding to the firmware update to the display 100. In step S27, the smart device 200 transmits the updated version firmware to the display 100. In step S28 , the display 100 executes a setting action accordingly according to the display setting instruction.

[0036] In the second embodiment of the present invention, the connector 210 of the smart device 200 and the connector 110 of the display 100 both include HDMI interfaces, and information is transmitted between the smart device 200 and the display 100 via a display data channel (DDC). Specifically, in step S22, the smart device 200 reads the version information of the current version of the firmware of the display 100 from the display 100 via the display data channel (DDC). Specifically, in step S26, the smart device 200 transmits a display setting instruction (i.e., MCCS instruction) corresponding to the firmware update to the display 100 via the display data channel (DDC) and in accordance with the display control command set (MCCS) standard. In other words, in step S25, the smart device 200 converts the setting instruction into an MCCS instruction. Specifically, in step S27, the smart device 200 transmits the updated version of the firmware to the display 100 via the display data channel (DDC).

[0037] In the second embodiment of the present invention, in step S23, the smart device 200 connects to the server providing firmware through the network to determine whether there is an updated version of the firmware. The server providing firmware can be a remote server, such as an Over-the-Air (OTA) server, or a local server. In the first embodiment of the present invention, in step S24, when the smart device 200 determines that there is an updated version of the firmware, the smart device 200 downloads the updated version of the firmware from the firmware OTA server.

[0038] In the second embodiment of the present invention, in step S28, the display 100 executes the firmware update program accordingly according to the display setting instruction. Generally speaking, the firmware update of a traditional display needs to be performed through the USB interface of the display and using the hardware buttons and OSD on the display. If the display does not have a reserved USB interface, the display can only be sent to the manufacturer's maintenance point and the firmware update can be performed by engineers. Relatively speaking, through the display setting method 2000 of the second embodiment of the present invention, the user can perform the firmware update without using any hardware buttons or OSD on the display 100, which is convenient for the user to update the firmware of the display by himself. On the other hand, through the display setting method 2000 of the second embodiment of the present invention, the display 100 does not need to make hardware buttons thereon, so as to reduce the production cost of the display 100.

[0039] In some embodiments of the present invention, before step S11 of the display setting method 1000 of the first embodiment of the present invention and before step S21 of the display setting method 2000 of the second embodiment of the present invention, the remote control device 300 completes pairing with the smart device 200 through the display 100, so that the display 100 becomes a private display that can only be controlled by the remote control device 300. Figure 5 For example, steps S31 and S32 are added before step S11 of the display setting method 1000 of the first embodiment of the present invention. Figure 5 is a flow chart of a display setting method 3000 according to a third embodiment of the present invention. In step S31, the display 100 is powered on so that the display 100 displays a unique pairing code on its display screen, such as a two-dimensional code (such as a QR code, a PDF417 code, etc.), a one-dimensional code, a string of characters, or a pairing name, etc. In step S32, the remote control device 300 completes pairing with the smart device 200 through the unique pairing code displayed on the display screen of the display 100 (for example, the remote control device 300 scans the unique pairing code or types the unique pairing code, etc.), so that the display 100 becomes a private display that can only be controlled by the remote control device 300.

[0040] Specifically, in the third embodiment of the present invention, after the remote control device 300 has been paired with the smart device 200, other control devices except the remote control device 300 can no longer be paired with the smart device 200, and the display 100 cannot be controlled by the smart device 200 to perform setting actions. Generally speaking, the traditional digital video converter box with networking function does not limit that only a single remote control device can be paired with it, resulting in any remote control device being able to pair with the digital video converter box, and privacy cannot be protected. For example, any remote control device can view the browsing history of the digital video converter box through the display. In contrast, in the third embodiment of the present invention, a set of unique pairing codes is set, and if a specific remote control (i.e., the remote control device 300) is not used, the display 100 cannot be controlled by the smart device 200 to perform setting actions, and the relevant data of the smart device 200 cannot be viewed through the display 100.

[0041] In the third embodiment of the present invention, the display 100 becomes a private display that can only be controlled by the remote control device 300. When other control devices other than the remote control device 300 attempt to pair with the smart device 200 or attempt to control the display 100 to perform a setting action through the smart device 200, the smart device 200 transmits a display setting instruction to the display 100 to switch the input signal source of the display 100. Specifically, the smart device 200 transmits a display setting instruction (MCCS instruction) to the display 100 via the display data channel (DDC) and in accordance with the display control command set (MCCS) standard, so that the input signal source of the display 100 is switched to other external devices other than the smart device 200, such as external devices physically connected to other connectors of the display 100 (not shown, such as HDMI interface, DP interface, VGA interface, USB-C interface, etc.) different from the connector 110. In this way, any remote control device can no longer control the display 100 to perform a setting action through the smart device 200, so as to realize the function of the display 100 as a private display that can only be controlled by the remote control device 300.

[0042] In addition, in the third embodiment of the present invention, the display 100 becomes a private display that can only be controlled by the remote control device 300. When other control devices other than the remote control device 300 attempt to pair with the smart device 200 or attempt to control the display 100 to perform setting actions through the smart device 200, in addition to the above-mentioned method of switching the signal source of the display 100, the smart device 200 can also transmit MCCS instructions to the display 100 to control the display 100 from being controlled by other control devices, such as dimming the brightness of the display screen of the display 100, reducing the display resolution of the display screen of the display 100, making the display screen of the display 100 not display a picture, and making it impossible to use the physical buttons on the display 100 for operation, etc.

[0043] Specifically, the display 100 becomes a private display that can only be controlled by the remote control device 300. When other control devices other than the remote control device 300 attempt to pair with the smart device 200 or attempt to control the display 100 through the smart device 200 to perform setting actions, the smart device 200 will transmit the display setting command to the display 100 via the display data channel (DDC) and in accordance with the display control command set (MCCS) standard to lock the display 100 and prevent it from being controlled by other control devices. When the display 100 is locked, it can only be unlocked by an authorized unit through the network, or the smart device 200 can be reset. However, even if the smart device 200 is reset, the content of the smart device 200 cannot be forcibly obtained.

[0044] Figure 6 is a protection flow chart of a private display according to the third embodiment of the present invention. In step S41, the remote control device 300 completes pairing with the smart device 200 through the display 100, so that the display 100 becomes a private display that can only be controlled by the remote control device 300. In step S42, the smart device 200 determines whether other connectors of the display 100 are physically connected to other external devices. If so, it proceeds to step S44, otherwise it proceeds to step S43. In step S43, the smart device 200 determines whether other control devices other than the remote control device 300 transmit data to the smart device 200 to control the display 100 to perform setting actions. If so, it proceeds to step S44, otherwise it returns to step S41. In step S44, the smart device 200 transmits the display setting command to the display 100 via the display data channel (DDC) and in accordance with the display control command set (MCCS) standard. In step S45 , the input signal source of the display 100 is maintained to be from the smart device 200 and the display 100 does not respond to the external device physically connected to other connectors of the display 100 , so as to protect the display 100 from being controlled by the external device.

[0045] Figure 7 is a protection flowchart of a private display according to a third embodiment of the present invention. Figure 7 and Figure 6 Similar, the difference is Figure 7 Replace with step S55 Figure 6 In step S45, the input signal source of the display 100 is switched to the external device, and the extended display identification data (EDID) of the display 100 is changed to only support the minimum resolution and limit the use of resources of the external device on the display 100 to protect the display 100 from being easily controlled by the external device.

[0046] In summary, the present invention provides a display setting method that allows users to update the display firmware by themselves through a smart device, without using any physical buttons or screen setting menus (OSD) of the display, thereby improving the convenience of users in operation. In addition, the display setting method provided by the present invention also allows users to adjust the display parameters of the display through a smart device, without using any physical buttons or screen setting menus (OSD) of the display, thereby improving the convenience of users in operation, and also allows the display to not need to make hardware buttons thereon, thereby reducing the production cost of the display. Finally, the display setting method provided by the present invention allows the display to become a private display that can only be controlled by a unique remote control device. Without using the unique remote control device, it is impossible to control the display through a smart device to perform setting actions and it is impossible to view relevant data of the smart device through the display, thereby protecting the display from being controlled by an external device.
