Field of the Invention The present invention relates to a touch panel and a display device, and more particularly to a touch panel using a carbon nanotube as a transparent conductive layer and a display device using the same. [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 use of such an electronic device 视觉 视觉 visually confirms the display content of the display device located on the back surface of the touch panel by the touch panel ‘ while pressing the touch panel with a finger or a pen to perform a ladder operation, thereby operating various functions of the electronic device. According to the working principle of the touch screen and the transmission medium, the touch screens in the prior art are divided into four types, namely, resistive, capacitive, infrared, and surface acoustic waves. Among them, the capacitive touch screen is widely used due to its high accuracy and strong anti-interference ability. Capacitive touch screens of the prior art (see "Research on Continuous Film Capacitive Touch Screens", Li Shuben et al., Optoelectronics Technology, Vol. 15, P62 (1995)), a glass substrate, a transparent conductive layer, and A plurality of metal electrodes are disposed in the capacitive touch screen, and the material of the glass substrate is two glasses. The transparent conductive layer is a transparent material such as an oxidized tin oxide (ITO) or a bismuth tin oxide (AT0). The two electrodes are formed by printing a conductive metal (e.g., silver) having a low electrical resistance. Placed at each corner of the transparent conductive layer. Further, the transparent conductive layer is coated with the protective layer by a hardening or densification process of the liquid glass material, followed by heat treatment to form a hardened layer. Fee... When a touch object such as a finger touches the surface of the touch screen, a coupling capacitor is formed between the touch object such as a finger and the transparent conductive layer in the touch screen due to the human body electric field. For high-frequency currents, the capacitor is a direct conductor, and the touch of a finger or the like picks up a small current from the contact point. This current flows from the electrodes on the touch screen, 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 calculates the position of the touch point by accurately calculating the ratio of the four currents. . Therefore, the transparent conductive layer is an essential component for the touch screen. In the prior art, the transparent conductive layer usually adopts an ITO layer. However, the ITO layer as a transparent conductive layer has disadvantages such as insufficient mechanical and chemical durability. Further, the use of the ITO layer as the transparent conductive layer has a phenomenon in which the resistance value distribution is uneven, resulting in the problem that the capacitive touch screen of the prior art has low resolution and low precision of the touch screen. In view of this, it is indeed necessary to provide a touch screen having high resolution, high precision, and durability, and a display device using the touch screen. SUMMARY OF THE INVENTION A touch screen includes a substrate, a transparent conductive layer disposed on a surface of the substrate, and a plurality of electrodes, wherein the plurality of electrodes are spaced apart from each other and electrically connected to the transparent conductive layer connection. Wherein, the transparent conductive layer further comprises a carbon nanotube layer, wherein the carbon nanotube layer comprises a plurality of carbon nanotube long lines arranged in parallel and spaced apart, and the two ends of each of the nano carbon tubes are respectively Two opposing electrodes are electrically connected, and each of the electrodes is electrically coupled to one end of at least one long line of carbon nanotubes. A display device comprising a touch screen, the touch screen comprising a substrate; a transparent conductive layer disposed on a surface of the substrate; and a plurality of electrodes respectively spaced apart and transparent with the 8 200928911 The conductive layer is electrically connected; a display device is disposed opposite to a surface of the transparent conductive layer facing the substrate of the touch screen. Wherein the transparent conductive layer further comprises a carbon nanotube layer, the tube 1 comprises a plurality of long carbon nanotubes arranged in parallel and spaced apart, and the two ends of the long non-meter carbon tube are respectively Electrically coupled to two opposing electrodes, and each of the electrodes is electrically coupled to one end of at least one of the long lines of carbon nanotubes. Compared with the prior art touch screen and display device, the touch screen and the display device provided by the present technical solution have the following advantages: First, since a plurality of carbon nanotube long lines in the transparent conductive layer are parallel and spaced apart, the The transparent conductive layer has better mechanical properties, so that the above transparent conductive layer has better mechanical strength and toughness. Therefore, by using the above-mentioned nano carbon tube long line as a transparent conductive layer, the durability of the touch screen can be correspondingly improved. Further improving the durability of the display device using the touch screen; second, the plurality of carbon nanotube long lines in the transparent conductive layer are parallel and spaced apart, so that the transparent conductive layer has a uniform resistance ❹ distribution and light transmittance. And each of the electrodes is electrically connected to one end of a long line of at least one of the carbon nanotubes in the transparent conductive layer, so that the two electrodes at the touch point connected to the long line of the carbon nanotube can be detected. The current changes to more accurately determine the position of the touch point, thereby facilitating the improvement of the touch screen and the display device using the touch screen Resolution and accuracy. [Embodiment] Hereinafter, the technical solution will be further described in detail with reference to the accompanying drawings. Referring to FIG. 1, FIG. 2 and FIG. 3, the touch screen 20 includes a substrate 22, a transparent layer 24, a protective layer 26, and a plurality of electrodes 28. The base 2 has a surface 221 and a second surface opposite to the first surface 221. The transparent electrode 24 is disposed on the first surface of the base 22 and is disposed on the surface 221 of the monthly isoelectric layer; the plurality of electrodes 2 are disposed apart from each other and electrically connected to the transparent conductive layer 24 for forming an equipotential on the transparent surface surface.

Preferably, the plurality of electrodes 28 are respectively recorded on opposite ends of the dielectric layer, and the substrate 22 is a curved surface or a planar structure. The substrate μ is formed of a hard material such as glass, stone, diamond or plastic or a flexible material. The substrate 22 serves primarily as a support. The transparent conductive layer 24 includes a plurality of carbon nanotube long wires 240 arranged in parallel and spaced apart, and a transparent conductive layer provided with a plurality of carbon nanotube long wires 24 ( ) is disposed correspondingly with a plurality of electrodes. Each of the two ends of each of the long carbon nanotubes is electrically connected to two opposite electrodes, and each of the electrodes is electrically connected to one end of the long line of at least one of the transparent conductive layers 24.

The position on the long line of the carbon nanotubes in turn combines the position of the long carbon nanotube line on the touch screen 20 to determine the touch location of the touch point on the touch screen 20. Therefore, the touch screen provided by the embodiment of the technical solution is advantageous for improving the resolution and accuracy of the touch screen 20. In the present embodiment, the size of the long carbon nanotube line can be obtained according to actual needs. In this embodiment, a 4-inch substrate is used to grow a super-sequential carbon nanotube array, and the diameter of the long carbon nanotubes may be from 0.5 nm to 100 μm, and the length thereof is not limited. The carbon nanotubes in the long line of the nanotube can be one or more of a single-walled carbon nanotube, a double-walled carbon nanotube, and a multi-walled carbon nanotube.

The carbon nanotube array is a plurality of pure carbon nanotube arrays formed of a plurality of carbon nanotubes that are parallel to each other and perpendicular to the substrate. The carbon nanotube array is substantially the same area as the above substrate. By controlling the growth conditions as described above, the super-aligned carbon nanotube array contains substantially no impurities such as amorphous carbon or residual catalyst metal particles. In the present embodiment, the carbon source gas may be selected from a chemically active carbon gas compound such as acetylene, ethylene or decane. The preferred carbon source gas in the present embodiment is acetylene; the shielding gas is nitrogen* gas or an inert gas, which is preferred in this embodiment. The shielding gas is argon. 〇 It can be understood that the carbon nanotube array provided by the embodiments of the present technical solution is not limited to the above preparation method' and may be a graphite electrode constant current arc discharge deposition method, a laser evaporation deposition method or the like. : Pulling a carbon nanotube from the carbon nanotube array using a stretching tool to obtain a carbon nanotube film or a nano carbon tube wire. The preparation of the stomach & mC tube film or nano carbon tube wire specifically includes the following steps (a) selecting a plurality of carbon nanotube segments of a certain width from the above carbon nanotube arrays. Width of the tape contacts the carbon nanotube array to select a plurality of carbon nanotube bundles of a certain width; (b) stretches the plurality of nanotube bundles at a certain speed along the growth direction of the base 12 200928911 Forming - a continuous tantalum carbon tube thin _ Nylon carbon tube filament. During the above stretching process, the plurality of carbon nanotube bundles are gradually separated from the substrate by pulling under the pulling force, and the selected carbon nanotube bundles are respectively combined with other nanotube bundles due to the van der Waals force. The two are continuously pulled end to end to form a carbon nanotube film or a carbon nanotube wire. The carbon nanotubes = membrane or nanocarbon tube bundles of a parallel nep (four) tube bundle. The carbon nanotubes in the carbon nanotubes Ο 或者 2 or the carbon nanotubes are substantially parallel to the stretching direction of the carbon nanotube film or the carbon nanotube filament. The microstructure of the nano retanning film obtained in this embodiment can be seen in Fig. 4. Step 1. The long-term treatment of the carbon nanotube film or the nephron tube by using an organic solvent or applying a mechanical external force. _L Description Step - The damaged carbon nanotube film or the nano carbon tube wire can be treated with a cereal agent to obtain a long-term carbon nanotube tube. The specific treatment process includes: dropping the organic solvent on the surface of the carbon nanotube film or the surface of the nano carbon tube by infiltrating the non-carbon carbon nanotube thinner carbon nanotube wire. The organic _ is a volatile organic compound such as ethanol, hydride, (d), dioxane or gas, and is preferably used in the present embodiment. The carbon nanotube film or the nano carbon tube filament is infiltrated by an organic solvent, and then, under the action of volatile organic solvent_surface tension, the carbon nanotubes are thinner than the carbon nanotubes of the carbon nanotubes (four). Partially integrated into the nano & bundle 'so 'the carbon nanotube film shrinks the growth line. The nano carbon tube long line ^ volume ratio is small 'no H and has good mechanical strength and secret, application ^ machine solvent treatment The latter carbon nanotube film or nano carbon tube long wire can be conveniently applied to the macroscopic field. 13 200928911 The above steps—the prepared carbon nanotube film or the nano carbon tube wire can also be obtained by applying mechanical external force—nano Long carbon tube. The long carbon line of the carbon nanotube is a stranded structure composed of a plurality of carbon nanotubes connected end to end. The specific treatment process includes: providing a tail (10) to accommodate the carbon nanotube film or nano carbon The spinning shaft of the tube yarn. After the tail of the spinning shaft is combined with the nanotube film or the carbon nanotube wire, the spinning shaft is rotated (four) the carbon nanotube film or the carbon nanotube Silk, forming a long line of carbon nanotubes. Understandably, The rotation mode of the above-mentioned spinning shaft is not limited to m to m inversion, or combination of forward rotation and reverse rotation. The above-described prepared carbon nanotube array can also be processed by applying mechanical external force to obtain a long line of carbon nanotubes. The nano carbon f long line is a twisted wire structure composed of a plurality of carbon nanotube bundles connected end to end. The specific processing process includes: providing a spinning shaft with a tail carbon nanotube array. The tail of the spinning shaft After combining with the nano-revision array, the carbon nanotubes begin to wrap around the shaft. The spinning shaft is rotated in a rotating manner and moved away from the array of carbon nanotubes. When the spinning axis moves, the long carbon nanotubes begin to be spun. 'Other carbon nanotubes can be wrapped around the long line of the carbon nanotubes to increase the length of the carbon nanotubes. It can be understood that the spinning axis The rotation mode is not limited, it can be forward rotation, reverse rotation, or combination of forward rotation and reverse rotation.
