Description of the Invention: Field of the Invention Field of the Invention The present invention relates to an acceptable external image, and more particularly to an external input device that can be used as a stand-alone display device. [Prior Art] Flat-panel displays, such as liquid crystal displays, plasma displays, etc., are usually used in conjunction with a computer mainframe to display image (image) signals from the host computer (4). Therefore, when the computer is turned off, the flat panel display has a function. However, because of this, when the computer is turned off or has not been used for a long time, the (four) flat panel display will be redundant and take up space because it cannot be used. Therefore, if the flat panel display is turned off by the computer and can be operated by the user for other purposes, the application of the flat panel display can be more flexible and diversified. To this end, as shown in FIG. 1, U.S. Patent No. 6,930,655 discloses a display system i (9) having a single-core nuclear and PC peripheral mode, the display system 1 having a display 102 and a mode disposed in the display 1 〇 2 Switching circuit 114 and a subsystem 112. The mode switching circuit 114 is connected to a personal computer 104 and a peripheral device 1〇6, which determines whether the personal computer 104 is powered on and connected to the display by detecting the potential provided by the personal computer to the connector pin of one of the displays 102. . When the personal computer 1〇4 is not turned on or the display 102 is not connected, the mode switching circuit 114 causes the display 102 to operate in a stand-alone mode and connects the peripheral device 106 to the subsystem 112, so the sub-system 200919439 system ii2 can use the periphery. The function of the device 1〇6, the image generated after the interaction appears on the display 1G2. When the personal computer (PC) 1G4 is powered on and connected to the display, the mode switching circuit 114 causes the display 1 and the peripheral device to work: in the pc peripheral mode 'subsystem i 12 delivers its original character to the personal computer 104, so the display 1 The 〇 2 is used to display an image generated by the computer 〇 4 and the personal computer 104 can use the functions of the peripheral device 1 〇 6. In addition, the display H 1G2 also allows the user to control the mode switching circuit 114 in a manual switching manner. In particular, in the case where the personal computer is turned on and connected to the display 102, for example, when the personal electric (four) 1〇4 is in a sleep state, the mode switching circuit 114 disclosed in the above U.S. patent cannot correctly discriminate the state to enter the state. Stand-alone mode 'so let the user work in stand-alone mode with manual switching. The above-mentioned Wu Guoqian case has reached 4 more ways of displaying the display 102 and the surrounding 1G6 by the mode switching circuit 1H. When the display U) 2 is in the stand-alone mode, the subsystem 112 is matched with the peripheral device 1 () 6, and the specific function can be completed; when the single mode is skipped, the display of the n 1G2 and the peripheral device (10) becomes the peripheral device of the personal computer HM. . For example, when the subsystem ιΐ2 is a jpEG arranging device and the peripheral device H)6 is a storage medium such as a card reader or a hard disk drive, the display 1 〇 2 has a field digital image read by the storage material 1G6 in the stand-alone mode. Function; after the stand-alone mode, the individual (4) (10) can use the display 102 to display images and access the data of the storage medium 1〇6. For the self-computer, but because it is based on the detection of the connection state of the display and the personal computer connection mode, this switching method can not correctly determine the personal hm 1 () 2 connection but is in a sleep state 'so in this case 6 200919439 : The user must switch the display to the stand-alone mode by manual switching. Moreover, the display 1〇2 and the peripheral device I 〇6 must work in the same working mode and the same mode switching, so that the display system 100 is limited in the application. For example, the display system i (9) cannot accept the peripheral device I% to perform its stand-alone function while displaying the image signal of the personal computer 104. The display system, system! (9) It is also impossible to execute and display the subsystem 112 (four) image signal when the personal computer 1 4 is connected to the peripheral device 1G6. Moreover, in stand-alone mode, the display 1〇2 must be paired with the peripheral device i(10) to be able to express its specific functions (such as the aforementioned #JpEG decoding m2 and storage medium 1〇6, when the storage medium is missing. The device 112 cannot display its function), and in addition, it has no built-in unique application functions for the user to operate.

The switching circuit 161 receives the input mode control signal control of the system controller 133 of the control unit 13, and when receiving the aggregate input mode signal, sends the input signal of the input device 3, 4 to the external image via the hub 162. The signal source 2, and upon receiving the local wheeling mode signal, sends the input signals of the wheeling devices 3, 4 to the 5H control unit 13 via the output main controller 163. Therefore, the control unit 13 of the present embodiment controls the operation mode of the image wheeling unit 12 as follows: 13 200919439 it m ^ μ (1) When the system is turned on or reset, the default map of the memory 131 is displayed. Like the round-out list:, the controller 133 checks the core image display mode, the initial mode of the system controller 13疋2 is the external image, and the display mode control signal of the as_output is the sound mode of the display mode. The external image display mode of the external image signal is set to output as early as 12 (2). When the image output unit u is the input unit 16 is in the local input mode 2: image display mode and switching control switching When the signal is received, the display mode is output; the controller 133 receives the mode display, and the control signal is an external image display mode to display the image input port.兀12 Switch to the external image display display 槿 or: — (1) When the system is turned on or reset, the image controller unit 12 of the preset image output unit 12 in the system m° memory 131 is stupid. The initial mode of the native image display mode, the system controller + machine map is a native image of the non-mode control signal α like the Bell no-right signal, to the image output unit Xia 〗 〖Haiben The native image display mode of the machine image signal. < (7) When the image wheeling unit 12 receives the nailing machine in the external image controller 133, the display mode of the wheel is displayed as the image of the machine. The control circle image is not pulled (4) to rotate the image to the local image display mode. 2 cut () field image output unit 12 detects an abnormal external circle notification control unit 亓 17 4 round image δ ΐ ΐ 5 tiger and image output single 'hand, system controller 133 day win, system controller U3 will ; The 12 is set to output the local image signal of the local image display 14 200919439 mode and display an indication of an abnormal external image signal. The operation of the two units 13 to control the switching control unit 16 is as follows: = When the system is powered on or reset, if the core record (4) (3) presets the cut, two, and the initial mode of the early π 16 is a pooled input mode, the system is protected. The input mode control signal of the two outputs is a set input mode: the number word change control unit 16 is set to the aggregate input mode. — The system controller 133 receives the mode switching signal and switches the control: =^1 in the local input mode, "control 11133 causes the output of the input signal to be - the input mode signal is collected to switch the control unit 16 Switch to the aggregate input mode. (7) The system controller is in the local input mode of the switch control unit 16 2 breaks the function menu or the local function display area on the display panel, the domain is selected, and the external image signal is normal. When the switch control switch 16 is switched to the aggregate input mode. The main wheel is held in the $: When the power is turned on or reset, if the core memory ΐ3ι preset switching system = 16 initial mode is the local input mode, the system control The input mode control signal that is cut out is the local wheel mode signal to set the knife change control unit 16 to the local input mode. The unit system controller 133 receives the mode switching signal and switches the control chart. In the display mode, the secret control H 133 makes the wheel out/in the outer 7 round out mode control 15 200919439 The signal is - the machine turns into the die number, (4) (four) the local input mode. (3) When the image output unit (4) detects an abnormal notification control unit] 7 * 卩 image Λ 5 tiger combined signal is - the local dry:: / controller 133 makes the output input mode control input wedge signal, In order to control the switching in the local input mode, the path is set to 70 16 as early as. Therefore, according to the above description, the flat mode can be summarized into the following three types: Working mode 1 of the device 1 • External image display mode + aggregation input mode = The output unit 12 only processes the signal from the external image signal control unit 16 to input the input device 3, "transmission - I red to the outside. The image source is returned from the 詈 3, 4 β to the device 1 and the wheeling device 3 4 Peripheral device for external image signal source. *, 弋 local image display mode + local input mode in and two from ^ early ^ 12 stacking the local image signal from the control unit 13: and external image signal from the external image signal source 2, and cut The input signal of the wheeling devices 3, 4 is sent to the system controller 133 of the control unit ^. Therefore, the flat display device i and the input device have the built-in local function of the Μβ, and the flat display device ι also serves as the peripheral device of the image signal source. Thus, the user can operate and use its native function while displaying an external image signal. Mode 3: Local Image Display Mode + Collection Input Mode The image output unit 12 stacks the local image gas number from the control unit 13 and the external image signal from the external image signal source 2, but the switching control 16 200919439 The single t16 sends the input signals of the input devices 3, 4 to the external image signal source 2. Therefore, the flat display device 丨 is a peripheral device of the local function, and the input device 3, 4 周边 peripheral device of the external image signal source, and the flat display device 也是 is also the peripheral device of the external image signal source 2. Thus, the user can operate the external signal source 2 while displaying a local function image signal. The switching flow and operation mode of the flat display device 1 between the above three modes will be further explained below. Referring to FIG. 6 and FIG. 2, when the plane display device 1 connected to the external image signal source 2 is turned on or reset, as shown in step 6, the plane display device 1 is set in mode i, that is, its image output. The unit 12 only accepts external image signals from the external image signal source 2, and the switching control unit 16 sends the input signals of the input devices 3, 4 to the external image signal source 2. Therefore, when the user operates the input devices 3, 4, although the input devices 3, 4 are connected, the face display device! On the 'but actually send the input signal to the external image and 'in mode 1, as in step 62' image output unit] Mei Xun, and as in step 63, determine whether the external image signal 2 is positive or not External image signal, and inform the system controller (3) normal 'If step 64, the system controller 133 determines the mode switching key (5):, is it triggered (touch)? If not, it will remain in mode], if there is, then = mode, switch the flat display device to mode, and accept the image signal from the control unit, and the d = number stack, and make the switch control 16 The input device 3, 4: = 17 200919439 is sent to the system controller 133 of the control unit 丨3. At the same time, the control unit 13 causes the local image processor 122 of the image wheeling unit 12 to generate one of the phone book, the notepad, the moon, the clock, the computer, the exchange rate converter and the temperature display as shown in FIG. The function menu 7 (the local image signal display area) of the local function options such as the humidity display is displayed on the display panel 11, and an input is generated when one of the local function options is selected by the SD control button or the input devices 3, 4. When the signal is given to the control unit 13, the control unit 13 executes an application corresponding to the native function option. At this time, since the input device 3 (mouse) and the input device 4 (keyboard) are connected to the system controller 133 through the switching control unit 16, when the user moves the mouse 3, as shown in FIG. 5, the mouse 3 The generated coordinate signal will be decoded by a mouse decoder 134 preset in the system controller 133 and sent to the image output unit 12, so that a cursor corresponding to the movement of the mouse 3 is generated on the display panel 11, and when used, When the cursor of the mouse 3 is operated, in the function menu 7 t, for example, the computer, the option, the system controller 133 takes out the graphics and characters that generate the computer image from the core record L body 131 and sends the image to the image output. The local image processor 122 of the unit 12 is configured to display on the display panel n as shown in FIG. 8 - a virtual computer (the local image signal display area) for use. The user can select the virtual computer on the mouse. The digits and the different paykeys or & keyboard 4 directly input the numbers and arithmetic symbols for calculation. "In addition, as shown in FIG. 4, since the local application unit 18 includes the data memory 1 8 1 for storing the functions of the local device such as the electric thin and the five own books, the time is provided by using two: (4) RTC circuit 182, and one or more 18s for sensing, such as temperature, humidity, smoke, or toxic gas. 200919439 Therefore, the flat display device of the present embodiment is more powerful, clock, and note. This and the environmental sensing resources = machine two. For this reason, the control unit 13 makes the core memory (3) more

And the time display block 7 3 simultaneously displays a "long". Station, option and _,, close the 'Tiantian select resident' option, the time display block 73 is closed, but still receives the time information sent by the system control $133 and is in the long-standing display area ghost 74 (this The time information is continuously displayed in the machine image signal display area. If the close option is selected, the time display block 73 is closed and returned to the function menu / 〇 and when the control unit 13 is based on the input device 3, 4 or the 〇 SD control button 19 200919439 In the execution function menu 7, for example, the phone book, the function, the record data 13 related to the phone book in the data memory 181 of the local machine ==_18 is read and the local image of the image output unit 12 is read. After processing, it is output to the display panel 丨 1. Therefore, as shown in FIG. 1A, the display panel 11 displays a phone book 71 (the local image signal display area) for the user to view the previously recorded call. Information (eg with mouse 3) , the upper page, the next page option), or the user can also click the "Add" option on the phone book 71 to re-export (10) disk 4 to output the phone information you want to add in the phone book 71 ( The input signal of the keyboard 4 is decoded by the keyboard decoding H U5 built in the system controller 133 and then output to the local image processor ! 22 of the image output unit 12 and stored in the data memory 181 through the application device interface 134. Finally, the user simply clicks on the phonebook 71 and closes, and the option can return to the function menu 7 to select other functions., an environment sensing function option in the function menu 7, for example, temperature , is selected by the input device 3, 4 or the 〇SD control button 15 to generate a round-trip signal to the system controller 133 a temple system controller 133 to obtain the environment sensing function option (ie, "temperature,") An environmental sensing information (ie, temperature) measured by the environment sensor 183 (eg, a temperature sensor) is sent to the image output unit 12 to display environmental sensing information (ie, temperature) on the display panel. Similarly, other such as The ambient humidity sensing function can also be implemented as described above. Finally, as shown in step 66 of FIG. 6, the user only needs to touch the mode switching key 151 again, and the system controller 133 switches the working mode to mode 1 'to make the plane display. The device 1 only accepts the external image signal input by the external image signal source 2 and sends the input signals of the input devices 3, 4 to the external image signal 20 200919439 source 2. In addition, when the flat display device 1 is still in mode 2 Mode switching can also be performed, that is, as in step 67, when the system controller 133 determines that the user moves the mouse 3 cursor to the display other than the function menu 7 (or display blocks 71, 72, 73) in the display panel u. When the area is selected, in step 68, the system controller 133 first determines whether the external image signal outputted by the external image signal source 2 is normal, and if so, determines that the user wants to retain the currently executed local function. In this case, the input (10) of the input device 3, 4 is sent to the (4) image signal source 2. In this case, as in step 69, the control unit 13 switches the flat display device 1 to mode 3, so that the switching control unit 16 will input Device 3 , * is connected to the external image signal source 2 through the hub 162, and the input signals of the input devices 3, 4 are sent to the external image signal source 2 through the hub 152. Therefore, while the user controls the external image signal source 2 through the input device 3, 4 input command, the function originally turned on or in the mode 2 is continued without being turned off. Therefore, in mode 3, when the user wants to use the local function of the function menu 7 t again, then (4) 7G is passed, that is, the user presses the key switch key 151 once, and the system switches to mode 2. ^Of course, in step 68, when the system controller 133 determines that the image of the external image 5 is not normal, the system remains in mode 2' and displays an abnormal external image signal. Tips. Red again, returning to step 63, when the system controller 133 determines that the output image signal like the source 2 is abnormal, the system controller 133 J automatically sets the system to mode 2, and automatically The display panel 11 displays 21 200919439 not correct external image signal prompts and function menu 7, so that the user can directly select the local function options listed in the function menu 7 through the wheeling devices 3, 4 and use the function, as above Said. In addition, the system controller 133 can also input the external image signal according to the condition of the image output unit 12 to input the image output unit. 2 If the external image signal is normally input, the operation flow is as described above. Otherwise, the system is forced to switch to the mode < h, and the working mode is automatically switched by judging whether the external image signal is normal or not. In addition, the system controller 133 can also perform mode switching according to an option in the 主SD main menu. That is to say, a "mode switch" option can be added to the QSD main menu. When the flat display device i is in the mode, the user selects the coffee control button 150, and the mode switch "option", the system controller m That will receive the option signal and switch the flat display device i to mode 2. When the device i is in mode 2, the user clicks the mouse or OSD control button 150, mode switch, option, system The controller (1) receives the option signal and switches the flat display device 1 to the mode operation. As shown in the above description, the flat display device 1 of the present invention switches the mode switching signal according to the mode switching key hi by the control unit, respectively - Display mode control (4) control image output single AI and control the signal control switching & 以 in the wheel-in mode, so that the plane display device can switch between two different working modes according to the user selection = It can provide more flexible and active applications. In addition, regardless of the external image signal source image signal, the flat display device can be operated according to the user's choice, = 22 200919439 杈 2, and accept the local image signal and accept Enter the input signal of the device and interact with it. In addition, the 'flat display device 提供 provides the built-in local function in mode 2 for the user to operate, so that the flat display device does not display the external image m number.
