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 sensing, red 0 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 Si〇2 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 which 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 number of point spacers (Dot 200929637
Spacer)設置在上透明導電層與下透明導電層之間。其中， 該上透明導電層與該下透明導電層通常采用具有導電特 性的銦錫氧化物（indium Tin 0xide，IT〇)層（下稱汀〇層）。 當使用手指或筆按壓上基板時，上基板發生扭曲，使得按 壓處的上透明導電層與下透明導電層彼此接觸。通過外接 的電子電路分別向上透明導電層與下透明導電層依次施 加電壓，觸摸屏控制器通過分別測量第一導電層上的電壓 變化與第二導電層上的電壓變化，並進行精確計算，將它 轉換成觸點坐標。觸摸屏控制器將數字化的觸點坐標傳遞 給中央處理器。中央處理器根據觸點坐標發出相應指令， 啓動電子設備的各種功能切換，並通過顯示器控制器控制 顯示元件顯示。 然而，ΙΤΟ層作爲透明導電層通常釆用離子束濺射或 蒸鍍等工藝製傷，在製備的過程，需要較高的真空環境及 需要加熱到200〜300°C ’因此’使得ΙΤ〇層的製備成本較 ❹高。此外，ΙΤΟ層作爲透明導電層具有機械性能不够好、 難以彎曲及阻值分布不均勻等缺點。另外，ιτ〇在潮渴的 空氣中透明度會逐漸下降。從而導致先前的電阻式觸摸屏 及顯示裝置存在耐用性不够好，靈敏度低、線性及準確性 較差等缺點。 有#于此’確有必要提供一種耐用性好，且靈敏度高、 線性及準確性强的觸摸屏及顯示裝置。 【發明内容】 -種觸摸屏，包括：一第一電極板，該第一電極板包 7 200929637 括一第一基體及一第一導電層設置在該第一基體的下表 面；以及一第二電極板，該第二電極板與第一電極板間隔 設置’該第二電極板包括一第二基體及一第二導電層設置 在該第二基體的上表面；其中，上述第一導電層和第二導 電層：的至少-個導電層包括至少兩個重叠的奈米碳管 層’每一奈米碳管層包括多個定向排列的冑米碳管，且相 鄰的兩個奈米碳管層中的奈米碳管沿同一方向排列。 -㈣不裝置’包括：—觸摸屏’該觸摸屏包括一第 -電極板及-第二電極板，該第__電極板包括—第一基體 及第¥電層&置在該第一基體的下表自，該第二電極 板與第-電極板間隔設置，且包括一第二基體及一第二導 電層設置在該第二基體的上表面；及-顯示設備，該顯示 設備正對且靠近上述觸摸屏的第二電極板設置；其中，上 述第導電層和第二導電層中的至少—個導電層包括至少 兩個重叠的奈米碳管層，每一奈米碳管層包括多個定向排 ❹列的奈米碳管’且相鄰的兩個奈求碳管層中的奈米碳管沿 同一方向排列。 本技術方案實施例提供的釆用至少兩個重叠設置的奈 米碳管層作爲透明導電層的觸摸屏及顯示裝置具有以下優 點八，由于奈米碳管具有優異的力學性能，則由定向 排歹J的不米碳s組成的單個奈米碳管層具有較好的勃性及 機械强度’故采用該至少兩個奈米碳管層作透明導電層， 可以相應的提高觸摸屏的耐驗，進而提高使用該觸摸屏 的顯不裝置的耐用性；其二，由于奈米碳管具有優異的導 8 200929637 電性能’則由定向排列的奈米碳管組成的奈米碳管層具有 均勻的阻值分布，因而，采用上述至少兩層奈米碳管層作 透明導電層，可以相應的提高觸摸屏及顯示裝置的分辨率 和精確度。 【實施方式】 以下將結合附圖詳細說明本技術方案提供的觸摸屏及 顯示裝置。' 请參閱圖1及圖2，本技術方案實施例提供一種觸摸 屏1〇’該觸摸屏10包括一第一電極板12，一第二電極板 14以及叹置在第一電極板12與第二電極板14之間的多個 透明點狀隔離物16。 該第一電極板12包括一第一基體12〇Spacer) is disposed between the upper transparent conductive layer and the lower transparent conductive layer. The upper transparent conductive layer and the lower transparent conductive layer are usually made of an indium tin oxide (IT) layer (hereinafter referred to as a tantalum layer) having a conductive property. When the upper substrate is pressed with a finger or a pen, the upper substrate is twisted so that the upper transparent conductive layer and the lower transparent conductive layer at the pressing contact 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. Convert to contact coordinates. The touch screen controller passes the digitized contact coordinates to the 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. However, the ruthenium layer is usually used as a transparent conductive layer by ion beam sputtering or vapor deposition. In the process of preparation, a high vacuum environment is required and heating to 200 to 300 ° C is required. The preparation cost is relatively high. In addition, the ruthenium layer as a transparent conductive layer has disadvantages such as insufficient mechanical properties, difficulty in bending, and uneven distribution of resistance. In addition, the transparency of ιτ〇 will gradually decrease in the thirsty air. As a result, previous resistive touch screens and display devices have disadvantages such as insufficient durability, low sensitivity, linearity, and poor accuracy. It is indeed necessary to provide a touch screen and display device with high durability, high sensitivity, linearity and accuracy. A touch screen includes: a first electrode plate, the first electrode plate package 7 200929637 includes a first substrate and a first conductive layer disposed on a lower surface of the first substrate; and a second electrode a second electrode plate is spaced apart from the first electrode plate.

The touch screen and the display device using the at least two overlapping carbon nanotube layers as the transparent conductive layer provided by the embodiments of the present technical solution have the following advantages. 8. Since the carbon nanotubes have excellent mechanical properties, the directional drainage is performed. The single carbon nanotube layer composed of J carbon-free s has good boobility and mechanical strength. Therefore, the at least two carbon nanotube layers are used as the transparent conductive layer, which can improve the durability of the touch screen. Improve the durability of the display device using the touch screen; secondly, because the carbon nanotube has excellent conductivity 8 200929637 'the electrical performance', the carbon nanotube layer composed of the aligned carbon nanotubes has a uniform resistance. The distribution, therefore, using the at least two layers of carbon nanotubes as the transparent conductive layer can correspondingly improve the resolution and accuracy of the touch screen and the display device.
