The hardness of the protective layer 36 is 7H (H is the Rockwell hardness test, unloading The depth of the indentation remaining under the initial test force, except for the main test force). It will be appreciated that the hardness and thickness of the protective layer 36 can be selected as desired. The protective layer 36 may be directly bonded to the transparent conductive layer 34 by a bonding agent. Furthermore, in order to reduce the electromagnetic interference generated by the display device 'avoiding an error in the signal emitted from the touch panel 30', a shielding layer 35 may also be provided on the second surface 322 of the substrate 32. The shield layer 35 may be formed of a transparent conductive material such as an indium tin oxide (ITO) film, a tin oxide film (ITO) film, or a carbon nanotube film. The carbon nanotube film can be a aligned or otherwise structured carbon nanotube film. In this embodiment, the carbon nanotube film comprises a plurality of carbon nanotubes, and the plurality of carbon nanotubes are oriented in the above-mentioned carbon nanotube film, and the specific structure thereof may be the same as that of the transparent conductive layer 34. The carbon nanotube film acts as an electrical grounding point and acts as a shield, thereby enabling the touch screen 30 to operate in a non-interfering environment. 09712827(^单单Α〇1(Η第15/30 pages 1013287013-0 1373727 __July 26, 2011 shuttle replacement page [0038] In addition, the touch screen 30 further includes a touch screen controller 39, The touch screen controller 39 is for controlling and calculating information touched by the user. The display screen 180 further includes a display controller 182 for controlling data input or output of the display screen 180. [0039] A specific process of displaying the portable computer 200 according to the second embodiment of the present technical solution through the touch of the touch screen 30 will be specifically described below. [0040] In use, a predetermined voltage is applied to the transparent conductive layer 34. The voltage is applied through the electrode 38. The transparent conductive layer 34 is formed to form an equipotential surface on the transparent conductive layer 34. The user visually confirms the display of the display screen 180 disposed behind the touch screen 30 while pressing or approaching the touch screen by a touch object 150 such as a finger or a pen. When the protective layer 36 of 30 is operated, a coupling capacitor is formed between the touch object 150 and the transparent conductive layer 34. For high frequency current, the capacitor is a direct conductor. The finger draws a portion of the current from the contact point. This current flows out of the electrode on the touch screen 30, respectively, and the current flowing through the four electrodes is proportional to the distance from the finger to the four corners. The touch screen controller 39 passes this Accurate calculation of the four current ratios results in the location of the touch point. Thereafter, the touch screen controller 39 transmits the digitized touch position data to the computer host 190 through the built-in input port; after that, the computer host 190 processes the received data. Then, the processed data is transmitted to the display controller 182 of the display 180 through the built-in output port, so that the display 180 can be displayed according to the data accepted by the display controller 182, so that the user's data is in and out. The display computer 180 is correspondingly displayed on the display screen. [0041] The portable computer provided by the embodiment of the present technical solution adopts a touch screen containing a carbon nanotube, and has the following advantages: First, due to the use of the carbon nanotube touch 1282# single number A〇101 Page 16 of 30 1013287013-0 1373727 Modified on July 26, 2011, the replacement page touch screen can be directly input. And the text data, so as to replace the traditional keyboard and mouse input devices, simplifying the structure of the portable computer, reducing the thickness, thereby making the portable computer more convenient to carry. Second, because the carbon nanotubes are wet Under the condition of good transparency, the use of the carbon nanotube layer as the transparent conductive layer of the touch screen can make the touch screen have better transparency, which is beneficial to improve the resolution of the portable computer using the touch screen. The carbon nanotube has excellent mechanical properties, and the carbon nanotube layer composed of carbon nanotubes has good toughness and mechanical strength. Therefore, the carbon nanotube layer is used as a transparent conductive layer of the touch screen, and the touch screen can be correspondingly improved. Durability, which in turn improves the durability of a portable computer using the touch screen; fourthly, because of the excellent electrical conductivity of the carbon nanotubes, the carbon nanotube layer composed of carbon nanotubes has a uniform resistance distribution, thus The use of the above carbon nanotube layer as a transparent conductive layer can correspondingly improve the resolution and precision of the touch screen The accuracy, in turn, increases the resolution and accuracy of the portable computer to which the touch screen is applied.
