Description of the Invention: [Technical Field] The present invention relates to a touch screen and a display device, and more particularly to a touch panel using a carbon nanotube and a display device using the same. [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 with translucent touch panels are mounted in front of display devices such as liquid crystals. Equipment is gradually increasing. The user of such an electronic device visually confirms the display content of the UI device located on the back of the touch panel by the touch panel, and presses the touch panel with a finger or a pen to operate. Thereby, various functions of the electronic device can be operated. [0003] According to the working principle of the touch screen and the transmission medium, the previous touch screens are divided into four types, namely, resistive, capacitive, infrared, and surface acoustic wave. Resistive touch screens and capacitive touch screens are widely used (K. Noda, K_Tanimura, Electronics 〇 and Communications in Japan, Part 2, Vo 1. 84, No. 7, P40 (2001); Li Shuben, Wang Qingdi, Ji Jianhua , Optoelectronic Technology, Vol. 15, P62 (1995)). [0004] The conventional resistive touch screen generally includes a first substrate, a first transparent conductive layer is formed on the first surface of the first substrate, and a second substrate is formed on the second surface of the second substrate. a layer of the first transparent conductive layer opposite to the second transparent conductive layer; and a plurality of dot spacers disposed on the first transparent conductive layer and the second transparent conductive layer between. Wherein, the 098127641 Form No. A0101 Page 3 / 39 pages 0982047410-0 201108051 A transparent conductive layer and a second transparent conductive layer are generally made of an indium tin oxide (Indium Tin Oxide, ΙΤ 0) layer (under the layer) Weigh ΙΤ 0 layer). When the first substrate is pressed with a finger or a pen, the first substrate is twisted such that the first transparent conductive layer and the second transparent conductive layer at the pressing point are in contact with each other. The voltage is sequentially applied to the first transparent conductive layer and the second transparent conductive layer by an external electronic circuit, and the electronic circuit can detect the pressed position. Further, the electronic circuit can initiate various functional switching of the electronic device based on the detected pressed position. [0005] The capacitive touch screen of the prior art includes a glass substrate and a transparent conductive layer. In the capacitive touch panel, the transparent conductive layer is a transparent material such as indium tin oxide (IT0) or antimony tin oxide (ITO). When a touch object such as a finger touches the surface of the touch screen, a coupling capacitor is formed between the touch object and the transparent conductive layer in the touch screen due to the human body electric field. For high-frequency currents, the capacitance is a direct conductor, and the touch of a finger or the like draws a small current from the contact point. The touch screen controller accurately calculates this current to get the touch point: ·. Therefore, improving the conductivity of the transparent conductive layer will help improve the accuracy and sensitivity of the touch screen.

Specifically, in use, a predetermined voltage is applied to the electrode 28 to the transparent conductive layer 24, thereby forming an equipotential surface on the transparent conductive layer 24. The user visually confirms the display of the display device 530 disposed behind the touch screen 20, and when the user touches or approaches the transparent protective layer 26 of the touch screen 20 by a touch object 570 such as a finger, the touch object 570 and the transparent conductive layer 24 form a Face-to-face capacitance For high-frequency current, the capacitor is a direct conductor, so the finger draws a part of the current from the contact point. This current flows out from the electrode 28 of the touch screen 20 and flows through the four electrodes. The current is proportional to the distance from the finger to the four corners, and the touch screen controller 5 4 得出 derives the position of the touch point by accurately calculating the ratio of the four currents. The 'touchscreen controller 540' then transmits the digitized touch location data to the central processor 550. The central processor 550 then receives the touch location data described above and executes it. Finally, central processor 550 transmits the touch location data to display controller 560 to display touch information from contact 570 on display device 530. Form No. A0101 Page 22 of 39 nq8<201108051 [0063] It will be understood that the second embodiment of the touch screen provided by the present invention can also be used in the above display device. [0064] The touch screen using the carbon nanotube metal composite layer as the transparent conductive layer and the display device using the touch screen provided by the embodiment of the invention have the following advantages: First, because the carbon nanotubes and the metal have good mechanical properties, The carbon nanotube metal composite layer composed of a carbon nanotube and a metal has good toughness and mechanical strength, and is resistant to bending, so that the durability of the touch cymbal can be improved accordingly, thereby improving the display device using the touch screen. Durability, secondly, because the carbon nanotube metal composite layer has high light transmittance, the transparency of the touch screen can be improved, thereby improving the transparency of the display device using the touch device; and third, due to the carbon nanotubes The metal composite layer comprises a plurality of uniformly distributed carbon nanotubes, and the carbon nanotubes have excellent electrical conductivity, and in addition, the surface of each of the carbon nanotubes in the carbon nanotube metal composite layer is formed with metal conductive# Dream, the metal conductive material has good electrical conductivity, so 1 the nano tube metal composite layer has a good electrical conductivity and a low electrical resistivity. The resistance distribution of the sentence, therefore, the use of the above-mentioned carbon nanotube metal composite layer as a transparent conductive layer can relatively improve the sensitivity and accuracy of the touch screen, thereby improving the sensitivity and accuracy of the display device using the touch screen. Fourthly, when the material of the substrate in the practice of the present invention is a flexible material, a flexible touch device can be prepared, which is suitable for use in a flexible display device. [0065] In summary, the present invention has indeed met the requirements of the invention patent, and the patent is filed according to law-t$. The above is only a preferred embodiment of the invention, and the patent cannot be restricted by this. range. Any person skilled in the art will be able to make equivalent modifications or variations in accordance with the spirit of the present invention. 098127641 Form No. A0101 Page 23 of 39 0982047410-0 201108051 All should be covered by the following patents.
