Electronics and Communications in Japan, Part 2， Vol.84， P39-45(2001) » [0004] 先前的電阻式觸摸屏一般包括一上基板，該上基板的下 表面形成有一上透明導電層；一下基板，該下基板的上 表面形成有一下透明導電層；以及多個點狀隔離物（Dot 096151269 表單編號A0101 第3頁/共26頁 1003318265-0 1354920 100年08月31日’梭正替換頁The present invention relates to a touch screen and a display device using the same, and more particularly to a carbon nanotube-based touch screen and A display device using the touch screen. [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 display elements such as liquid crystals are gradually increasing. . The user of such an electronic device operates by pressing the touch panel with a finger or a pen while visually checking the display content of the display element located on the back surface of the touch panel via the touch panel. 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 prior touch screens are generally divided into four types, namely, resistive, capacitive sensing, infrared, 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〇2Anchor Layer, and Application to a Resistive Touch Panel" Kazuhiro Noda, Kohtaro Taniraura. Electronics and Communications in Japan, Part 2, Vol .84, P39-45 (2001) » [0004] The prior resistive touch screen generally includes an upper substrate, the upper surface of which is formed with an upper transparent conductive layer, and the lower substrate has a transparent surface formed on the upper surface thereof. Conductive layer; and a plurality of dot spacers (Dot 096151269 Form No. A0101 Page 3 / Total 26 Page 1003318265-0 1354920 100 Aug. 31
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採用具有導電 特性的姻錫氧化物（Indium Tin Oxide, ΙΤ0)層（下稱 ΙΤ0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。 [0005] 然而，ΙΤ0層作爲透明導電層通常採用離子束濺射或蒸鍍 等工藝製備，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ΙΤ0層的製備成本較高 。此外，ΙΤ0層作爲透明導電層具有機械性能不够好、難 以彎曲及阻值分佈不均勻等缺點。另外，ΙΤ0在潮濕的空 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。 [0006] 有鑒於此，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】

二導電層142時可直接黏附在所述第—基體12〇或第二基 體140上。 & [0031] 另外，可使用有機溶劑處理上述黏附在第一基體12〇或第 二基體140上的奈米碳管帶狀膜結構。具體地，可通過試 管將有機溶劑滴落在奈米碳管帶狀膜結構表面浸潤整個 奈来碳管帶狀膜結構。該有機溶劑爲揮發性有機溶劑， 如乙醇、曱醇、丙網、二氣乙烧或氣仿，本實施例中採 用乙醇》該奈米碳管帶狀膜結構經有機溶劑浸濶處理後 ，在揮發性有機_的表面張力的作用下，該奈米碳管 帶狀膜結構可牢固地貼附在基體表面，且表面體積比二 小，黏性降低，具有良好的機械强度及動性。 剛所述第-導電層122中的奈求碳管帶狀膜結構的兩端與所 述第一電極124電連接，所述第二導電層142中的奈米碳 管帶狀膜結構的兩端與所述第二電極144電連接。所述第 -導電層122中的奈来碳管帶狀膜結構的排列方向可偏離

另外，該第一電極板12上表面可進一步設置一透明保護 膜126，該透明保護膜126可由氮化矽、氧化矽、苯丙環 丁烯（BCB)、聚酯以及丙烯酸樹脂等材料形成。該透明保 護膜126也可採用一層表面硬化處理、光滑防刮的塑料層 ，如聚對苯二曱酸乙二醇酯（PET)膜，用於保護第一電 極板12，提高耐用性。該透明保護膜126還可用於提供一 些其它的附加功能，如可以减少眩光或降低反射。 [0035] 此外，可選擇地，爲了减小由顯示設備産生的電磁干擾 ，避免從觸摸屏10發出的信號産生錯誤，還可在第二基 體140的下表面上設置一屏蔽層（圖未示）。該屏蔽層可 由銦錫氧化物（IT0)薄膜、銻錫氧化物（ΑΤΟ)薄、鎳 金薄膜、銀薄膜膜或奈米碳管薄膜等導電材料形成。本 實施例中，所述的屏蔽層包含一奈米碳管薄膜，該奈米 碳管薄膜中的奈米碳管的排列方式不限，可爲定向排列
