[0025] In order to further clarify the technical means adopted by the present application and its effects, the following describes in detail the preferred embodiments of the present application and its accompanying drawings.

[0026] Please refer to Figures 1 to 4 The present application provides a notebook computer, which comprises a shell 2, a mainboard 4 installed in the shell 2, and a decorative sheet 6 installed on the shell 2 and covering the mainboard 4. One side of the mainboard 4 facing the decorative sheet 6 is provided with a keyboard touch area 42 and a mouse touch area 44 located at one side of the keyboard touch area 42, and the other side of the mainboard 4 is provided with a central processing unit 46 and a touch chip 48 electrically connected with the central processing unit 46.

[0027] The decorative sheet 6 is provided with a keyboard identification area 62 corresponding to the keyboard touch area 42 and a touchpad identification area 64 corresponding to the mouse touch area 44. The keyboard identification area 62 is provided with a key identification 620 of the keyboard to indicate that touching the key identification 620 can realize the input of the corresponding key of the keyboard. The key identification 620 is formed by silk printing process.

[0028] The decorative sheet 6 is a mylar decorative sheet, which has flexibility to improve the touch operation feeling and can make the touch surface flat, and can also be of different colors according to the needs to play a decorative role and meet the individualized requirements of users. The thickness of the decorative sheet 6 is 0.4-0.6 mm, and the material of the decorative sheet 6 is polycarbonate (PC).

[0029] As shown in Figure 2 and Figure 4 The keyboard touch area 42 and the mouse touch area 44 are respectively provided with a first capacitive touch sensing circuit 420 and a second capacitive touch sensing circuit 440, and the first capacitive touch sensing circuit 420 and the second capacitive touch sensing circuit 440 are respectively electrically connected with the touch chip 48 to realize the touch operation.

[0030] The principle of realizing the touch operation of the present application is as follows:

[0031] 1. When the user touches the keyboard identification area 62 of the decorative sheet 6, the touch chip 48 obtains the position coordinates of the touch position according to the change of the capacitance value of the first capacitive touch sensing circuit 420 at the corresponding keyboard touch area 42, identifies the corresponding preset input key according to the position coordinates, and transmits the identification result to the central processing unit 46 to realize the key input operation of the keyboard.

[0032] 2、When the user touches the touch panel identification area 64 of the decorative sheet 6, the touch chip 48 obtains touch information (such as cursor movement or confirmation click key information) at the touched position according to the change of the capacitance value at the second capacitive touch sensing circuit 440 at the corresponding mouse touch area 44, and transmits the touch information to the central processing unit 46 to realize mouse operation.

[0033] Specifically, the shell 2 comprises a base 21 and a face shell 22 rotatably connected with the base 21, and the upper surface of the base 21 is provided with a downwardly recessed mounting groove 212, and the main board 4 is mounted in the mounting groove 212.

[0034] Specifically, one side of the main board 4 facing the decorative sheet 6 is flush with the upper surface of the base 21, and the decorative sheet 6 is attached to the main board 4 and the base 21.

[0035] Preferably, the decorative sheet 6 is attached to the main board 4 and the base 21 by back adhesive. When attached, a layer of back adhesive can be coated on the side of the decorative sheet 6 close to the main board 4, and then the decorative sheet 6 is attached to the main board 4 and the base 21.

[0036] Specifically, the notebook computer further comprises a display screen 7 mounted on the face shell 22 and a camera 8 mounted on the face shell 22 and located on the side of the display screen 7 away from the base 21.
