Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a touch screen and a display device. [Prior Art] [0002] 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 in front of a display such as a liquid crystal are gradually increasing. . The user of the electronic device visually confirms the display content of the display located on the back surface of the touch panel by the touch screen, and presses the touch screen to operate by a finger or a pen. Thereby, various functions of the electronic device can be operated. r [0003] According to the working principle of the touch screen and the transmission medium, the existing touch-screens are generally divided into four types, namely, resistive, capacitive sensing, infrared, and surface acoustic wave. Resistive touch screens and capacitive touch screens are widely used in display devices due to their high resolution, high sensitivity and durability.现有 [0004] The existing resistive touch screen generally comprises an upper substrate, the upper surface of the upper substrate is formed with an upper transparent conductive layer; the lower substrate, the upper surface of the lower substrate is formed with a transparent conductive layer; and a plurality of dot isolation A Dot Spacer is disposed between the upper transparent conductive layer and the lower transparent conductive layer. The dot spacer is used to achieve electrical insulation between the upper transparent conductive layer and the lower transparent conductive layer in a non-pressed state. The upper transparent conductive layer and the lower transparent conductive layer are usually made of an indium tin oxide (ITO) layer (hereinafter referred to as an IT0 layer) having a conductive property. When the substrate is pressed with a finger or a pen, the upper substrate is twisted so that the upper transparent guide at the pressing place 098145179 Form No. 1010101 Page 3 of 28 0982077224-0 201124898 The electric layer and the lower transparent conductive layer are in contact with each other. The voltage is sequentially applied to the upper transparent conductive layer and the lower transparent conductive layer through the external electronic circuit, and the touch screen controller measures the voltage change on the first conductive layer and the voltage change on the second conductive layer, respectively, and performs accurate calculation. Converted to contact coordinates. The touch screen controller passes the digitized contact coordinates to the central processor. The central processor issues corresponding commands according to the contact coordinates, initiates various function switching of the electronic device, and controls the display of the display through the display controller. [0005] However, the I TO layer as a transparent conductive layer is usually prepared by a process such as ion beam sputtering or evaporation, and a high vacuum environment is required in the preparation process and heating to 200 to 300 ° C is required, thus The preparation cost of the IT0 layer is high. In addition, after the IT0 layer is continuously bent, the resistance at the bend is increased, which has the disadvantage that the transparent conductive layer has insufficient mechanical and chemical durability. In addition, since a plurality of dot spacers are generally disposed in a dot form between the upper transparent conductive layer and the lower transparent conductive layer, the upper transparent conductive layer and the lower transparent conductive layer are realized in a non-pressed state. Electrical insulation performance is not good enough. SUMMARY OF THE INVENTION [0006] In view of the above, it is necessary to provide a touch panel and a display device which are excellent in durability and can better achieve electrical insulation between the upper transparent conductive layer and the lower transparent conductive layer in a non-pressed state. [0007] A touch screen includes: a first electrode plate, the first electrode plate includes a first substrate, a first conductive layer and two first electrodes. The first conductive layer is disposed on the first substrate a surface, the two first electrodes are electrically connected to the first conductive layer; and a second electrode plate, the second 098145179 Form No. A0101 Page 4 / Total 28 Page 0992077224-0 201124898 [0008] Ο [0009 [0012] [0012] The electrode plate is spaced apart from the first electrode plate, the second electrode plate includes a second substrate, a second conductive layer and two second electrodes, and the second conductive layer is disposed On the surface of the second substrate and opposite to the first conductive layer, the two second electrodes are electrically connected to the second conductive layer; wherein the touch screen further comprises a transparent insulating layer disposed on the first Between a conductive layer and a second conductive layer, and at least one of the first conductive layer and the second conductive layer comprises a carbon nanotube structure. A display device using the touch panel described above, further comprising a display, the touch screen being disposed on a side of the display facing the user. Compared with the prior art, since the transparent conductive layer using the carbon nanotube structure has uniform resistance distribution and light transmittance and excellent mechanical properties, the resolution and accuracy of the touch panel and the display device using the above transparent conductive layer are compared. Higher and more durable. In addition, the transparent insulating layer is disposed between the first conductive layer and the second conductive layer, and the transparent insulating layer can better realize the electric power between the upper transparent conductive layer and the lower transparent conductive layer in a non-pressed state. insulation.

The carbon nanotubes are arranged in a preferred orientation along the same film. The preferred orientation refers to the direction in which the carbon nanotubes are pulled and the overall extension direction of the 'nanocarbon tubes is substantially the same direction. Too much of the majority of the carbon nanotubes extend substantially parallel to the surface of the ^(tube). Further, in the carbon nanotube film, the tube is connected by van der Waals force. Specifically, most of the nanocarbon/mother-nano carbon nanotubes extending substantially in the direction of the second carbon nanotube film are passed through the carbon nanotubes adjacent to each other in the extension direction, and the Valli is connected end to end. There are randomly arranged carbon nanotubes in the carbon nanotube film, and these green sputums do not significantly affect the overall orientation of most of the carbon nanotubes in the nanocarbon film. The wave of carbon nanotubes does not require a large-area carrier support, and as long as the support is provided on both sides, it can maintain its own membranous state, that is, the carbon nanotubes are placed (or When the two supports are arranged at intervals - the distance between the two supports, the carbon nanotube film _ vacant remains in its own state.

Preferably, the carbon nanotubes of the carbon nanotube rolled film are parallel to the surface of the substrate or the carbon nanotube film: the surface is different according to the manner of rolling, the carbon nanotube The carbon nanotubes in the rolled film have different arrangements. Because the carbon nanotubes in the carbon nanotube film are attracted to each other through the van der Waals force, the carbon nanotube film is a self-supporting structure, which can be self-supported without substrate support. .
