[0037] Please refer to Figures 1 to 3 , Figure 3 FIG. 1 is a state machine diagram of the shortcut controller 100 according to an embodiment. Figure 1 and Figure 2 As shown, the shortcut controller 100 includes a switch key 110. The switch key 110 is used to switch the mode of the shortcut controller 100. Figure 3 As shown, the shortcut controller 100 has an on-screen display mode (OSD mode) M1 and a computer shortcut key mode M2. The user can switch the shortcut controller 100 to the on-screen display mode M1 or the computer shortcut key mode M2 ​​through the switch key 110. When the shortcut controller 100 is in the on-screen display mode M1, the screen parameter adjustment of the display 200 is performed corresponding to the pressing operation of the shortcut controller 100. When the shortcut controller 100 is in the computer shortcut key mode M2, the shortcut operation of the shortcut controller 100 is performed to perform a shortcut operation of the computer 300.

[0038] That is, the shortcut controller 100 of this embodiment has two functions: adjusting the screen parameters of the display 200 and performing shortcut operations on the computer 300. The signal contents required by these two functions are different, so the disclosure allows the shortcut controller 100 to achieve dual functions through appropriate signal conversion operations.

[0039] Please refer to Figure 4 , Figure 41 is a block diagram of a display assembly 1000 according to an embodiment. The display assembly 1000 includes the above-mentioned shortcut controller 100, the above-mentioned display 200 and the above-mentioned computer 300. The shortcut controller 100 includes the above-mentioned switch key 110, a plurality of the above-mentioned control keys 120i, a processing unit 130 and a data transmission unit 140. The switch key 110 is used to switch the mode of the shortcut controller 100, such as a lever, a rebound button, or a touch sensor pad. The control key 120i is used for the user to input signals by pressing, touching, rotating, etc., such as a rebound button, a touch sensor pad, a 360-degree direction rod, a turntable, or a roller. The processing unit 130 is used to execute various processing procedures or judgment procedures, such as a circuit, a chip, a circuit board or a storage device for storing program codes.

[0040] The display 200 includes a display unit 210, a judgment unit 220, a screen adjustment unit 230, a command processing unit 240, a storage unit 250, a controller connection unit 260, a data transmission unit 270 and an image transmission unit 280. The display unit 210 is used to display an image, such as a display panel or a projection lens and an optical module. The judgment unit 220 is used to perform a judgment procedure. The screen adjustment unit 230 is used to perform a screen adjustment procedure. The command processing unit 240 is used to process commands. The judgment unit 220, the screen adjustment unit 230 and / or the command processing unit 240 are, for example, circuits, chips, circuit boards or storage devices storing program codes. The controller connection unit 260 is used to connect to the quick controller 100, such as a USB connection port, a Bluetooth communication module, an infrared transmission module or a WIFI transmission module. The data transmission unit 270 is used to transmit commands, such as a USB connection port, a Bluetooth communication module, an infrared transmission module or a WIFI transmission module. The image transmission unit 280 is used to receive images, such as a D-SUB port, a DVI-D port, an HDMI port, a DisplayPort port, a type-C port, a Bluetooth communication module, or a WIFI transmission module. Although the data transmission unit 270 and the image transmission unit 280 are both connected to the computer 300, they operate independently and transmit different contents. Even if the data transmission unit 270 and the image transmission unit 280 use the same type of port, the data transmission line L1 connected to the data transmission unit 270 is different from the image transmission line L2 connected to the image transmission unit 280. Even if the data transmission unit 270 and the image transmission unit 280 use the same type of transmission module, the data transmission channel used by the data transmission unit 270 is different from the image transmission channel used by the image transmission unit 280.

[0041] The computer 300 includes a data transmission unit 310, an image transmission unit 320 and a processing unit 330. The data transmission unit 310 is used to receive commands, such as a USB port, a Bluetooth communication module, an infrared transmission module or a WIFI transmission module. The image transmission unit 320 is used to transmit images, such as a D-SUB port, a DVI-D port, an HDMI port, a DisplayPort port, a type-C port, a Bluetooth communication module, or a WIFI transmission module. Although the data transmission unit 310 and the image transmission unit 320 are both connected to the display 200, they operate independently and the transmission contents are different. Even if the data transmission unit 310 and the image transmission unit 320 use the same type of port, the data transmission line L1 connected to the data transmission unit 310 is different from the image transmission line L2 connected to the image transmission unit 320. Even if the data transmission unit 310 and the image transmission unit 320 use the same type of transmission module, the data transmission channel used by the data transmission unit 310 is different from the image transmission channel used by the image transmission unit 320. The processing unit 330 is used to execute various processing programs, various analysis programs or various control programs, and is, for example, a circuit, a chip, a circuit board or a storage device storing program codes.

[0042] In this embodiment, through the above components, the display 200 can receive the screen adjustment command CM1 or the computer shortcut command CM2 from the shortcut controller 100. When the display 200 receives the screen adjustment command CM1, the display 200 can adjust at least one screen parameter; when the display 200 receives the computer shortcut command CM2, it can automatically convert the command and transfer it to the computer 300 for the computer 300 to perform shortcut operations. The operation of the above components is also described in detail with a flowchart below.

[0043] Please refer to Figures 5A-5B , Figures 5A-5B1 is a flow chart of an operation method of a display assembly 1000 according to an embodiment. In step S110, the processing unit 130 of the shortcut controller 100 determines whether the shortcut controller 100 is in the screen adjustment mode M1 or the computer shortcut key mode M2 ​​according to the switch key 110. For example, when the switch key 110 is switched, a switch signal S1 can be sent to the processing unit 130. After receiving the switch signal S1, the processing unit 130 can switch between the screen adjustment mode M1 and the computer shortcut key mode M2. Alternatively, the switch key 110 can output different mode signals (not shown) to the processing unit 130 according to different switch positions. After receiving the mode signal, the processing unit 130 can determine whether the shortcut controller 100 is in the screen adjustment mode M1 or the computer shortcut key mode M2. Alternatively, the switch key 110 can be triggered and output an actuation signal (not shown) to the processing unit 130 only when it is switched to a certain preset position. The processing unit 130 switches the shortcut controller 100 to the computer shortcut key mode M2 ​​only when receiving the activation signal.

[0044] If the shortcut controller 100 is in the screen adjustment mode M1 , the process proceeds to step S120 ; if the shortcut controller 100 is in the computer shortcut key mode M2 ​​, the process proceeds to step S150 .

[0045] In step S120, the processing unit 130 of the shortcut controller 100 determines whether the control key 120i of the shortcut controller 100 is pressed. When the control key 120i is pressed, a pressing signal S2i is output to the processing unit 130. If one or more control keys 120i are pressed, step S130 is entered.

[0046] In step S130, the processing unit 130 of the shortcut controller 100 generates a screen adjustment command CM1. In this step, the processing unit 130 adds a first flag FG1 to the pressing signal S2i to generate the screen adjustment command CM1. The first flag FG1 is, for example, added before the pressing signal S2i or after the pressing signal S2i.

[0047] Next, in step S140 , the shortcut controller 100 transmits the screen adjustment command CM1 to the display 200 via the data transmission unit 140 .

[0048] In addition, when the shortcut controller 100 is determined to be in the computer shortcut key mode M2 ​​in the above step S110 and then enters step S150, the processing unit 130 of the shortcut controller 100 determines whether the control key 120i of the shortcut controller 100 is pressed. When the control key 120i is pressed, a pressing signal S2i is output to the processing unit 130. If one or more control keys 120i are pressed, then enter step S160.

[0049] In step S160, the processing unit 130 of the shortcut controller 100 generates a computer shortcut command CM2. In this step, the processing unit 130 adds the second flag FG2 to the pressing signal S2i to generate the computer shortcut command CM2. The second flag FG2 is, for example, added before the pressing signal S2i or added after the pressing signal S2i.

[0050] Next, in step S170 , the shortcut controller 100 transmits the computer shortcut command CM2 to the display 200 via the data transmission unit 140 .

[0051] After step S140 and step S170, the process enters step S210. In step S210, the display 200 receives the screen adjustment command CM1 or the computer shortcut command CM2 through the controller connection unit 260. In this step, the controller connection unit 260 simply receives the information and transfers it to the determination unit 220.

[0052] Next, in step S220, the determination unit 220 of the display 200 determines whether the screen adjustment command CM1 or the computer shortcut command CM2 is received. In this step, the determination unit 220 can determine whether the screen adjustment command CM1 or the computer shortcut command CM2 is received according to the first flag FG1 or the second flag FG2. If the screen adjustment command CM1 is received, the process proceeds to step S230; if the computer shortcut command CM2 is received, the process proceeds to step S240.

[0053] In step S230 , the screen adjustment unit 230 of the display 200 adjusts at least one screen parameter according to the screen adjustment command CM1 .

[0054] In step S240 , the command processing unit 240 of the display 200 sends a detection signal Q1 to the computer via the data transmission unit 270 to detect whether the computer 300 uses the first operating system or the second operating system.

[0055] Next, in step S310 , the computer 300 receives the detection signal Q1 through the data transmission unit 310 .

[0056] Then, in step S320 , the processing unit 330 of the computer 300 inquires whether the computer 300 adopts the first operating system or the second operating system according to the detection signal Q1 , and generates a reply signal A1 .

[0057] Next, in step S330 , the computer 300 transmits a reply signal A1 to the display 200 via the data transmission unit 310 .

[0058] Then, in step S250 , the display 200 receives the reply signal A1 through the data transmission unit 270 .

[0059] Next, in step S260, the command processing unit 240 of the display 200 analyzes the response signal A1 to determine whether the computer 300 uses the first operating system or the second operating system. If the computer 300 uses the first operating system, the process proceeds to step S270; if the computer 300 uses the second operating system, the process proceeds to step S280.

[0060] In step S270, the command processing unit 240 of the display 200 converts the computer shortcut command CM2 into a human interface device (HID) command CM21' according to the first operating system. In this step, the storage unit 250 of the display 200 stores a command conversion table TB1 corresponding to the first operating system, and the command processing unit 240 converts the computer shortcut command CM2 into a human interface device command CM21' according to the command conversion table TB1.

[0061] In step S280, the command processing unit 240 of the display 200 converts the computer shortcut command CM2 into a human interface device command CM22' according to the second operating system. In this step, the storage unit 250 of the display 200 stores a command conversion table TB2 corresponding to the second operating system, and the command processing unit 240 converts the computer shortcut command CM2 into a human interface device command CM22' according to the command conversion table TB2.

[0062] Next, in step S290, the display 200 transmits the human interface device command CM21' or the human interface device command CM22' to the computer 300 through the data transmission unit 270. In this step, the data transmission unit 270 used by the display 200 is, for example, a USB port. The data transmission unit 270 transmits the human interface device command CM21' or the human interface device command CM22' through the data transmission line L1. The data transmission line L1 is different from the image transmission line L2 connecting the display 200 and the computer 300.

[0063] Then, in step S340, the data transmission unit 310 of the computer 300 receives the human interface device command CM21' or the human interface device command CM22'. In this step, the data transmission unit 310 used by the computer 300 is, for example, a USB port. The data transmission unit 310 receives the human interface device command CM21' or the human interface device command CM22' via the data transmission line L1. The data transmission line L1 is different from the image transmission line L2 connecting the computer 300 and the display 200.

[0064] Next, in step S350 , the processing unit 330 of the computer 300 performs a shortcut operation (such as shutdown, hibernation, restart, copy, paste, etc.) according to the human interface device command CM21 ′ or the human interface device command CM22 ′.

[0065] Through the above steps, the shortcut controller 100 has two functions: adjusting the screen parameters of the display 200 and performing quick operations on the computer 300. The display 200 can receive the screen adjustment command CM1 or the computer quick command CM2 from the shortcut controller 100. When the display 200 receives the screen adjustment command CM1, the display 200 can adjust the screen parameters; when the display 200 receives the human interface device command CM21' or the human interface device command CM22', the command can be automatically converted and transferred to the computer 300 for quick operations by the computer 300. The present disclosure allows the shortcut controller 100 to achieve dual functions through appropriate signal conversion.

[0066] In summary, the present invention provides a display component, an operating method of the display component, and a display. The display component includes a shortcut controller and a display. The shortcut controller includes a switch key and a plurality of control keys. The switch key is used to switch between a screen adjustment mode and a computer shortcut key mode. When the shortcut controller is in the screen adjustment mode and one or more of the plurality of control keys are pressed, a screen adjustment instruction is generated; when the shortcut controller is in the computer shortcut mode and one or more of the plurality of control keys are pressed, a computer shortcut instruction is generated. The display includes a judgment unit, a screen adjustment unit, a command processing unit, and a data transmission unit.
