A data storage unit 16, an OSD image reading unit 17, a touch panel controller 18, an instruction signal output unit 18, a key code data storage unit 20, and a keyboard position changing unit 21 are provided.

  The display device 1 is preferably an FP (flat panel display) such as a liquid crystal display, an EL display, or a plasma display in order to make the main body thin. The display device 1 may be a CRT display. The touch panel 12 is an input device provided for performing touch input on the display screen 11. When the touch input is performed, the touch panel 12 generates a voltage signal corresponding to the touch position.

  The image signal / I / F unit 13a is a communication control unit for the display device 1 to communicate with the computer 2 via the image signal cable 3a. The USB / I / F unit 13b is a communication control unit for the display device 1 to communicate with the computer 2 via the USB cable 3b. The image signal VS from the computer 2 is input to the image processing unit 14 via the image signal / I / F unit 13a. The image display unit 15 outputs a drive signal for driving the display screen 11 from the image signal VS processed by the image processing unit 14. As a result, an image from the computer 2 is displayed on the display screen 11.

  The OSD image data storage unit 16 is a memory that stores image data displayed by an on-screen display (OSD) function. In this specification, the OSD function means a function for displaying and operating a display setting screen or the like on a display screen. In the present embodiment, the OSD image data storage unit 16 stores keyboard image data 161 together with brightness adjustment image data, contrast adjustment image data, and the like.

  When a keyboard image display instruction is given by a predetermined operation, the OSD image reading unit 17 reads the keyboard image data 161 from the OSD image data storage unit 16 and outputs a keyboard image signal KS to the image processing unit 14. The image processing unit 14 superimposes the image signal VS from the computer 2 and the keyboard image signal KS, and outputs these signals to the image display unit 15. As a result, the keyboard image is superimposed on the image from the computer 2 and displayed on the display screen 11. The OSD image reading unit 17, the image processing unit 14, and the image display unit 15 correspond to the keyboard image display unit described in the claims.

  FIG. 2 is a front view of the display device 1. Below the display screen 11 of the display device 1, a power switch SW1, a brightness adjustment switch SW2, a contrast adjustment switch SW3, and a keyboard image display switch SW4 are provided. The brightness adjustment switch SW2, the contrast adjustment switch SW3, and the keyboard image display switch SW4 are OSD display switches. When the brightness adjustment switch SW2 and the contrast adjustment switch SW3 are pressed, the brightness adjustment image and the contrast adjustment image are displayed. Is displayed.

  Further, when the keyboard image display switch SW4 is pressed, the keyboard image 11a is displayed superimposed on the image from the computer 2. The user can give an operation instruction to the computer 2 by touch-inputting the key of the keyboard image 11a.

  Specifically, when touch input is performed on the touch panel 12 illustrated in FIG. 1, the touch panel controller 18 generates touch data indicating the touch position and inputs the touch data to the instruction signal output unit 18. The instruction signal output unit 18 includes a determination unit 191 and a key code output unit 192, and touch data from the touch panel controller 18 is input to the determination unit 191.

  The determination unit 191 determines whether or not the touch position is within the region of the keyboard image 11a, and outputs the touch data to the key code output unit 192 when the touch position is within the region of the keyboard image 11a. The key code data storage unit 20 stores key code data 201 indicating the correspondence between the keys of the keyboard image and the key codes. When touch data is input, the key code output unit 192 refers to the key code data 201 stored in the key code data storage unit 20 and outputs the key code of the key corresponding to the touch position of the keyboard image. . The key code is output as an instruction signal to the computer 2 via the USB / I / F unit 13b, whereby the computer 2 performs information processing according to the key code.

  Further, when the touch position is outside the region of the keyboard image 11a, the determination unit 191 outputs the touch data as it is to the USB / I / F unit 13b. Thereby, the touch data is output to the computer 2 as an instruction signal. Since images other than the keyboard image 11a are displayed by image signals from the computer 2, the computer 2 performs information processing based on the touch data.

  In FIG. 1, the OSD image data storage unit 16 and the key code data storage unit 20 are illustrated separately, but they may be the same memory.

  Further, the keyboard position changing unit 21 shown in FIG. 1 has a function of moving the position of the keyboard image by a predetermined operation. The keyboard image is moved by operating a key indicating a moving direction such as “↑” or “↓”. As a result, it is possible to avoid the inconvenience that the part to be browsed is hidden by the keyboard image, and the convenience of the input operation is improved.

  FIG. 3 is a flowchart showing an input operation procedure of the display device 1. For example, when the user presses the keyboard image display switch SW4 shown in FIG. 2 to give a keyboard image display instruction (step S1), the image processing unit 14 shown in FIG. 1 receives the keyboard image signal from the OSD image reading unit 17. Based on the above, a keyboard image is displayed on the display screen 11 (step S2). Subsequently, when touch input is performed on the touch panel 12 (“YES” in step S3), the determination unit 191 illustrated in FIG. 1 determines whether the touch position is within the keyboard image area based on the touch data from the touch panel controller 18. Is determined (step S4). When the touch position is within the keyboard image area (“YES” in step S4), the key code output unit 192 generates and outputs a key code from the touch data (step S5). On the other hand, when the touch position is outside the area of the keyboard image (“NO” in step S4), the determination unit 191 outputs the touch data as it is (step S6).

  As described above, in the display device 1, the keyboard image 11 a is displayed by the OSD image reading unit 17 reading out the keyboard image data 161 in the OSD image data storage unit 16 built in the display device 1. That is, the keyboard image 11a is displayed by the function of the display device 1 itself.

  Therefore, unlike the conventional configuration shown in FIG. 7, for example, even if the OS of the computer 2 does not start up even when the computer 2 is turned on, the display device 1 displays the keyboard image 11a on the display screen 11. Can be displayed, and the user can perform a startup operation on the computer 2 by touch-inputting the keyboard image 11a. Even when the computer 2 is frozen, the user can perform a restart operation on the computer 2 by displaying the keyboard image 11a and performing touch input. These effects will be described with reference to FIG.

  FIG. 4 is a flowchart showing the operation of the information processing system 100. First, the display device 1 and the computer 2 are turned on, that is, the information processing system 100 is turned on (step S11). Here, when the OS of the computer 2 does not start (“NO” in step S12), the user instructs the keyboard display on the display device 1 to display a keyboard image (step S13). Subsequently, activation of the OS of the computer 2 is instructed by a touch operation on the keyboard image (step S14).

  As a result, an OS activation instruction is transmitted from the display device 1 to the computer 2. Subsequently, when the OS of the computer 2 is activated (“YES” in step S12), but the OS of the computer 2 is frozen (“NO” in step S15), the user uses the keyboard in the display device 1 as in step S13. Display is instructed to display a keyboard image (step S16). Subsequently, the computer 2 is instructed to restart by a touch operation on the keyboard image (step S17). As a result, a restart instruction is transmitted from the display device 1 to the computer 2. Thereby, the process proceeds to step S12.

  In step S17, the end of the computer 2 may be instructed by a touch operation on the keyboard image. Thereby, the termination instruction is transmitted from the display device 1 to the computer 2, and the computer 2 can be safely terminated.

  Further, when the power of the display device 1 is supplied from the computer 2, it is desirable that the display device 2 is activated first when the computer 2 is turned on. Thereby, the instruction signal can be transmitted from the display device 1 to the computer 2 before the OS of the computer 2 is started.

  Further, even in a normal operating state, the computer 2 does not need to perform a calculation process for displaying a keyboard image, so that the burden of the calculation process of the computer 2 can be reduced as compared with the configuration shown in FIG.
