IX. INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The present invention relates to a portable computer, and more particularly to a portable computer. [Prior Art] In recent years, with the development of high performance and diversification of various electronic devices such as mobile phones and touch navigation systems, electronic devices in which a translucent touch panel is mounted on the front surface of a display device such as a liquid crystal are gradually increasing. The user of the electronic device visually confirms the display content of the display device located on the back of the touch screen through the touch screen, and presses the touch panel with a finger or a pen to operate. Thereby, various functions of the electronic device can be operated. The portable computer in the prior art usually integrates the liquid crystal display and the computer main body, and at least one touch screen is disposed on one surface of the liquid crystal display, and the touch screen can be used as a signal input device instead of a mouse and a keyboard for signals. The input, thereby controlling the various functions of the portable computer to turn on and off, and the input of text. The touch screen can be generally divided into four types according to the working principle and the transmission medium, which are resistive, capacitive inductive, infrared, and surface acoustic wave. Among them, resistive touch screens and capacitive touch screens are widely used in portable computers due to their high resolution, high sensitivity and durability. However, the capacitive and resistive touch screens of the prior art typically include an indium tin oxide layer (IT layer) as a transparent conductive layer, which is prepared by ion beam sputtering or > 贱 bond 4 process, Kazuhiro Noda et al.

The ITO layer is used in the preparation process, requires a high vacuum environment and needs to be heated to 200 to 30 CTC, thus making the production cost of Tingsheng sound higher. In addition, the prior art germanium layer as a transparent conductive layer has disadvantages such as insufficient mechanical properties, difficulty in bending, and uneven distribution of resistance. In addition, the transparency of the cockroach will gradually decrease in the moist air. As a result, the touch screen that is first cut and the portable computer that uses the touch screen have disadvantages such as low durability, low sensitivity, linearity, and poor accuracy. In view of this, it is necessary for a portable computer using a touch screen to have the advantages of durability, sensitivity, linearity, and accuracy. SUMMARY OF THE INVENTION A portable computer includes: a display screen having a display surface; a computer main body disposed on a surface of the far display surface of the display screen; and at least one touch screen, The touch screen is disposed on the display surface of the =7F screen, wherein the touch screen is a touch screen using a carbon nanotube as a transparent conductive layer. Compared with the prior art, the portable computer using the nano- and S-layer as the transparent conductive layer of the touch screen provided by the embodiment of the present technical solution has a black-and-white, one-to-one, and can be directly used due to the touch screen using a carbon nanotube. The input operation and text data 'and thus can replace the traditional keyboard and mouse input device' simplifies the structure of the portable computer and reduces the thickness, so that the portable computer is more convenient to carry. Second, since the carbon nanotubes have good transparency under wet and wet conditions, the use of a carbon nanotube layer as a transparent conductive layer of the touch screen can make the touch screen have better transparency, thereby facilitating the use of the carbon nanotube. The resolution of the touch screen of the laptop. Because of the excellent mechanical properties of the carbon nanotubes, the composition of the carbon nanotubes = carbon nanotubes has good properties and mechanical strength, so the nano-carbon layer can be used as a transparent conductive layer of the touch screen. Correspondingly, the durability of the touch screen is improved, thereby improving the durability of the portable computer using the touch screen. 4. Because of the excellent electrical conductivity of the carbon nanotube, the nano-carbon layer of the nano-carbon layer is uniform. The resistance distribution, therefore, the use of 纮Γ: pebbles anodic layer as a transparent conductive layer' can correspondingly improve the touch screen: and accuracy, thereby improving the resolution and accuracy of the portable computer using the touch screen.
