Field of the Invention The present invention relates to a touch panel and a display device using the same, and more particularly to a carbon nanotube-based touch panel 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 element such as a liquid crystal are gradually increasing. The user of such an electronic device operates by pressing the touch panel by a finger, a pen, or the like while visually checking the display content of the display element located on the back surface of the touch panel through the touch panel. Thereby, various functions of the electronic device can be operated. According to the working principle of the touch screen and the transmission medium, the previous touch screens are generally divided into four types, namely, resistive, capacitive inductive, red-Φ outer-line and surface acoustic wave. Among them, the resistive touch screen is the most widely used, please refer to the document "Production of Transparent Conductive Films with Inserted Si02 Anchor Layer, and Application to a Resistive Touch Panel" Kazuhiro Noda, Kohtaro Tanimura. Electronics and Communications in Japan, Part 2, Vol. 84, P39-45 (2001) ° The prior 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 lower transparent conductive layer; A plurality of dot spacers (Dot 6 200929635 'Spacer) are disposed between the upper transparent conductive layer and the lower transparent conductive layer. Wherein, the upper transparent conductive layer and the lower transparent conductive layer are usually made of an indium tin oxide (IT) layer having a conductive property (hereinafter referred to as an ITO layer). When the upper substrate of the finger or the pen (four) is used, the upper substrate is twisted so that the upper transparent conductive layer and the lower transparent conductive layer at the pressing portion are in contact with each other. The voltage is sequentially applied to the upper transparent conductive layer and the lower transparent conductive layer by an external electronic circuit, respectively. The touch screen & controller measures the voltage change on the first (four) layer and the voltage change on the second conductive layer, respectively, and performs accurate calculation. Convert it to contact coordinates. The touch screen controller passes the digitized contact coordinates to the ten central processor. The central processor issues a corresponding command according to the contact coordinates, activates various function switching of the electronic device, and controls the display of the display component through the display controller. ❹ *However, the '(four) layer as a transparent conductive layer is usually prepared by ion beam spraying or steaming. In the process of preparation, a high straight space environment is required and heating to 3 sails is required, thus making the layer of the layer The preparation cost is relatively good. In addition, the one-layer layer as a transparent conductive layer has disadvantages such as insufficient mechanical properties, difficulty in f-bending, and uneven distribution of resistance values. In addition, the transparency of the ιτ〇 in the thirsty air will gradually decrease, resulting in the disadvantages of the previous resistive touch screen, such as low sensitivity, low sensitivity, poor linearity and low accuracy. High sensitivity. In view of this, it is necessary to provide a touch screen and display device with good durability, linearity and accuracy.

The super-sequential carbon nanotube array is pure for a plurality of carbon nanotubes that are parallel to each other and grow perpendicular to the substrate. Nano carbon tube array. The above-mentioned controlled growth conditions, the super-sequential carbon nanotube array methyl group does not contain impurities such as amorphous carbon or residual catalyst metal particles, etc. The nano carbon array _ nano carbon The tubes are in close contact with each other to form an array by van der Waals force. The carbon nanotube array is substantially the same area as the above substrate. 12 200929635 ·' In this embodiment, the carbon source gas may be chemically selected such as acetylene, ethylene or decane. The preferred carbon source gas in the present embodiment is acetylene; the shielding gas is nitrogen or an inert gas, and the preferred shielding gas in this embodiment is argon.
