Description of the invention: [Technical field to which the invention pertains] The present invention relates to a desktop computer, and more particularly to a touch type desktop computer. [Prior Art] In recent years, with the development of various types of electronic devices such as mobile phones and touch navigation systems, and the development of diversified electronic devices, a light-sensitive touch panel is gradually installed on the front surface of a display device such as a liquid crystal. 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 to operate the operation by means of a finger or a pen. Thereby, various functions of the electronic device can be operated. The display screen of the desktop computer in the prior art can be a liquid crystal display. The surface of the liquid crystal display screen is provided with at least one touch screen, which can be used as a signal input device instead of a mouse and a keyboard for inputting signals, thereby controlling opening and closing of various functions of the desktop computer, and text The input of the ❹ word. The touch screen can be generally classified into four types according to the working principle and the transmission medium, and is respectively a resistive type, a capacitive sensing type, an infrared line type, and a surface acoustic wave type. Among them, resistive touch screens and capacitive touch screens are widely used in desktop computers due to their advantages such as resolution, high sensitivity and durability. However, the capacitive and resistive touch screens of the prior art typically include an indium tin oxide layer (ITO layer) as a transparent conductive layer, which is prepared by ion beam sputtering or sputtering, Kazuhiro Noda et al. in the catalog of Production of Transparent Conductive Films with Inserted 6 201015154 - Si〇2 Anchor Layer, and Application to a Resistive Touch Panel ( Electronics and Communications in Japan, Part 2, .V〇 1.84, P39-45 (2001)) describes the use of ITO/ Si02/PET layer, touch screen. The ITO layer is used in the preparation process, requires a high vacuum environment and needs to be heated to 200 to 300 ° C. In view of this, the preparation cost of the germanium layer is high. Further, the prior art ITO layer as a transparent conductive layer has disadvantages such as insufficient mechanical properties, difficulty in bending, and uneven distribution of resistance. In addition, ITO will gradually decrease in transparency in humid air. Thus ® causes the previous touch screen and the desktop computer using the touch screen to have poor durability, low sensitivity, linearity and poor accuracy. In view of this, it is necessary to provide a desktop computer using a touch screen which has the advantages of durability, sensitivity, linearity, and accuracy. SUMMARY OF THE INVENTION A desktop computer includes: a computer host; a display connected to the host computer via a data line, the display includes a display screen; and a touch screen disposed on the display surface The touch screen includes at least one transparent conductive layer, wherein the transparent conductive layer in the touch screen is a carbon nanotube structure. Compared with the prior art, the desktop computer using the carbon nanotube structure as the transparent conductive layer of the touch screen provided by the embodiments of the present technical solution has the following advantages: one of the 'operating commands and words can be directly input through the touch screen using the carbon nanotubes The data, which can replace the traditional input devices such as keyboards and mice, simplifies the structure of the desktop computer. Second, because the carbon nanotubes have good transparency under wet conditions at 7 201015154, the use of a carbon nanotube structure as a transparent conductive layer of the touch screen can make the touch screen have better transparency and thus facilitate Improve the resolution of desktop computers using this touch screen. Third, due to the excellent mechanical properties of the carbon nanotubes, the carbon nanotube structure composed of carbon nanotubes has good toughness and mechanical strength, so the carbon nanotube structure is used as a transparent conductive layer of the touch screen. The durability of the touch screen can be correspondingly improved, thereby improving the durability of the desktop computer using the touch screen. Fourth, since the carbon nanotubes have excellent electrical conductivity, the carbon nanotube structure composed of carbon nanotubes has a uniform resistance distribution, and thus, the above-mentioned carbon nanotube structure is used as a transparent conductive layer, which can be correspondingly Improve the resolution and accuracy of the touch screen, thereby increasing the resolution and accuracy of the desktop computer to which the touch screen is applied.
