The display panel 12 generates corresponding control according to the input signal of the touch panel 14. Fig. 2 is a block diagram showing the function of another embodiment of the notebook computer according to the present invention. The VGA (video graphics array) controller 22 is controlled by the central processing unit 25 for outputting an image signal, which is respectively transmitted to the 0506-A42003-TW/FINAL/4 201109884, a display panel 21 and a VGA/USB bridge controller 23 . The first display panel 21 displays a corresponding image according to the received image signal. In this embodiment, the image signal is a VGA image signal, and the VGA/USB bridge controller 23 is configured to convert the image signal into a first image signal conforming to the USB format and transmit the image signal to the touch panel 24, so that the touch panel .24 displays the corresponding image. When the central processing unit 25 executes the application 26, the VGA controller 22 controls the VGA controller 22 to generate and transmit φ a second image to the first display panel 21 according to an input signal received by the touch panel 24. 21 Display the second image. When the central processing unit 25 executes the application 26, a function menu or a control interface is generated on the touch panel 24 for the user to select a function to be used, or a virtual keyboard can be generated on the touch panel 24. For users to use. The control unit 27 receives an external signal input by the user through a button, a keyboard or a control interface on the touch panel 24, and controls the function of the touch panel 24 to be a touch panel, a touch panel, a tablet, a virtual keyboard or the like. When the function of the touch panel 24 is a touch screen, the user can directly control the notebook from the control interface displayed on the touch panel 24. When the function of the touch panel 24 is a touch panel, the user can control the cursor on the first display panel 21 through the touch panel 24. When the function of the touch panel 24 is a tablet, the user can write on the tablet, and recognize the word written by the user through the recognition software, and display it on the first display panel 21. When the touch panel 24 is simulated as a virtual keyboard through a program, the user can type directly through the virtual keyboard. In addition, the user can set the function of the touch panel 24 to touch the 0506-A42003-TW/FINAL/ 5 201109884 board or the touch screen. You can also set the quick key switch, or set the function of the touch panel to be the touchpad when executing some software. When the other software is executed, the function of the touch panel 24 is the touch screen. The user can also set the touch panel 24 to be simulated as a virtual keyboard through the program when certain specific programs are executed. Fig. 3 is a block diagram showing the function of another embodiment of the notebook computer according to the present invention. The image processing unit 33 generates an image signal which is transmitted to the first display device 31 and the VGA/USB bridge controller 34, respectively. The first driving circuit 35a of the first display device 31 receives the image signal for driving and displaying on the first display panel 36a. The VGA/USB bridge controller 34 provides a USB interface to the second display device 32 having a USB interface and converts the image signal into a first image signal conforming to the USB format. The USB/VGA bridge controller 3 in the second display device 32 converts the image signal into a second image signal and transmits it to the second driving circuit 35b. After receiving the second image signal, the second driving circuit 35b is driven and displayed on the second display panel. It should be noted that the second image signal may be the same as the image signal generated by the image processing unit 33, or it may be that the different image signal 'depends on the driving mode of the first touch panel.
