面安裝透光性的觸控面板的電子設備逐步增加。這樣的 電子設備的利用者通過觸控面板，一邊對位於觸控面板 背面的顯示設備的顯示内容進行視覺確認，一邊利用手 指或筆等方式按壓觸控面板來進行操作。由此，可以操 作電子設備的各種功能。 [0003] 按照觸控面板的工作原理和傳輸介質的不同，先前技術 中的觸控面板分爲四種類型，分別爲電阻式、電容式、 紅外線式以及表面聲波式。其中電容式觸控面板因準確 度較高、抗干擾能力強應用較爲廣泛。 [0004] 先前技術中的電容型觸控面板（請參見“連續薄膜電容式 觸控面板的研究”，李樹本等，光電子技術，vol 15， p62( 1995))包括一玻璃基板，一透明導電層，以及複數 金屬電極。在該電容型觸控面板中，玻璃基板的材料爲 納鈣玻璃。透明導電層爲例如銦錫氧化物（IT0)或銻錫 氧化物（ΑΤΟ)等透明材料。電極爲通過印製具有低電阻 的導電金屬（例如銀）形成。電極間隔設置在透明導電 0961493#單職 Α0101 第3頁/共30頁 1013075511-0 1364860 101年02月29日修正替換頁 層的各個角處。此外，透明導電層上塗覆有鈍化層。該 鈍化層由液體玻璃材料通過硬化或緻密化工藝，並進行 熱處理後，硬化形成。 [0005] 當手指等觸摸物觸摸在觸控面板表面上時，由於人體電 場，手指等觸摸物和觸控面板中的透明導電層之間形成 一個耦合電容。對於高頻電流來說，電容為直接導體， 手指等觸摸物的觸摸將從接觸點吸走一個很小的電流。 這個電流分別從觸控面板上的電極中流出，並且流經這 四個電極的電流與手指到四角的距離成正比，觸控面板 控制器通過對這四個電流比例的精確計算，得出觸摸點 的位置。 [0006] 因此，透明導電層對於觸控面板為一必需的部件，先前 技術中透明導電層通常採用ITO層，然，ITO層目前主要 採用濺射或蒸鍍等方法製備，在製備的過程，需要較高 的真空環境及加熱到200〜300°C，因此，使得ITO層的製 備成本較高。此外，ΙΤ0層作爲透明導電層具有機械和化 學耐用性不够好等缺點。進一步地，採用ITO層作透明導 電層存在電阻阻值分布不均勻的現象，導致先前技術中 的電容式觸控面板存在觸控面板的分辨率低、精確度不 高等問題》 【發明内容】 [0007] 有鑒於此，確有必要提供一種分辨率高、精確度高及耐 用的觸控面板，以及一種方法簡單、成本低的觸控面板 的製備方法及使用該觸控面板的顯示裝置。 [0008] 一種觸控面板，該觸控面板包括一基體；一透明導電層 1013075511-0 _49380織 A()1Q1 ^ 4 1 ^ 30 1 1,364860 1〇1年〇2月29曰核正替換頁 ，該透明導電層設置於上述基體的一表面；以及至少兩 個電極*該至少兩個電極間隔設置並與該透明導電層電 連接"其中，上述透明導電層包括一奈米碳管層，該奈 米碳管層包括各向同性或沿一固定方向取向或不同方向 取向排列的複數奈米碳管。 • [0009] 一種觸控面板的製備方法，包括以下步驟：提供一奈米 碳管陣列及一基體，該奈来碳管陣列形成於一基底；擠 壓上述奈米碳管陣列獲得一奈米碳管層形成在基體的一 個表面；以及提供至少兩個電極，並將至少兩個電極間 隔設置並與上述奈米碳管層形成電連接，從而形成所述 的觸控面板。 [0010] 一種顯示裝置，其包括一觸控面板，該觸控面板包括一 基體，一透明導電層，該透明導電層設置於上述基體的 一表面，以及至少兩個電極，該至少兩個電極間隔設置 並與該透明導電層電連接；一顯示設備，該顯示設備正 對且靠近觸控面板的基體設置。其中，上述透明導電層 包括一奈米碳管層，該奈米碳管層包括各向同性或沿一 固定方向取向或不同方向取向排列的複數奈米碳管。 [0011] 與先前技術相比較，本技術方案提供的觸控面板、觸控 面板的製備方法及顯示裝置具有以下優點：其一，由於 奈米碳管在所述的奈米碳管層中通過凡德瓦爾力相互吸 引，緊密結合，形成由複數奈米碳管組成的自支撑結構 ，從而使得上述的奈米碳管層具有較好的機械強度和韌 性，故，採用上述的奈米碳管層作透明導電層，可以相 應的提高觸控面板的耐用性，進而提高了使用該觸控面 1013075511-0 09614938#單編號A〇101 第5頁/共30頁 1364860 101年02月29日梭正替換k 板的顯示裝置的耐用性。其二，所述奈米碳管層包括各 向同性或沿一固定方向取向或不同方向取向排列的複數 奈来碳管。故，採用上述的奈米碳管層作透明導電層， 可使得透明導電層具有均勻的阻值分布和較好的透光特 性’從而提高觸控面板及使用該觸控面板的顯示裝置的 分辨率和精確度。其三，由於奈米碳管層為通過一施壓 裝置擠壓奈米碳管陣列獲得，製備方法簡單，且該方法 無需真空環境和加熱過程，故採用上述方法製備的奈米 碳官層作透明導電層，有利於降低觸控面板及使用該觸 控面板的顯示裝置的成本。 【實施方式】 乂下將結合附圖對本技術方案作進一步的詳細說明。 [0013] 明參閱圖1和圖2

由於所述奈米碳管層包括各向同性或沿一固定方向取向 或不同方向取向排列的複數奈米碳管。因此所述奈米碳 管薄膜具有很好的透光特性和阻值分布，故採用上述的 奈米碳管層作透明導電層可以提高觸控面板的分辨率和 精確度。 [0017] 本技術方案實施例中獲得的奈米碳管層的厚度爲0. 5奈米 〜100微米，奈米碳管層的長度及寬度不限。該奈米碳管 層包括各向同性或沿一固定方向取向或不同方向取向排

壓力的作用下奈米碳管陣列與生長的基底分離，從而形 成由複數奈米碳管組成的具有自支撑結構的奈米碳管薄 膜；之後，將上述奈米碳管薄膜通過導電粘結劑如導電 銀膠等粘結在基體22的第一表面221。其二，將上述基體 22的第一表面221直接覆蓋在上述奈米碳管陣列上；提供 一施加裝置施加一定的壓力於基體第二表面222上；在壓 力的作用下奈米碳管陣列與生長的基底分離，從而形成 由複數奈米碳管組成的具有自支撑結構的奈米碳管薄膜 粘附在基體22的第一表面221。 [0031] 另外，在施壓的過程中，奈米碳管陣列在壓力的作用下 會與生長的基底分離，從而形成由複數奈米碳管組成的 具有自支撑結構的奈米碳管薄膜，且所述的複數奈米碳 管基本上與奈米碳管薄膜的表面平行。本技術方案實施 例中，施壓裝置爲一壓頭，壓頭表面光滑，壓頭的形狀 及擠壓方向决定製備的奈米碳管薄膜中奈米碳管的排列 、

轴狀壓頭沿不同方向礙壓時，可獲得奈米碳管沿不同方 向取向排列的奈米碳管薄膜。 [0032]可以理解，當採用上述不同方式擠壓上述的奈米碳管陣 列時，奈米碳管會在壓力的作用下傾倒，並與相鄰的奈 米碳管通過凡德瓦爾力相互吸引、連接形成由複數奈米 碳官組成的具有自支撑結構的奈米碳管薄膜。所述的複 數奈米碳管與該奈米碳管薄膜的表面基本平行並爲各向 同性或沿一固定方向取向或不同方向取向排列。另外， 在廢力的作用下，奈米碳管陣列會與生長的基底分離， 從而使得該奈米碳管薄膜容易與基底脫離。 闺本技術領域技術人貞應明白，上述奈米碳#陣列的傾倒 程度（傾角）與壓力的大小有關，壓力越大，傾角越大 。製備的奈米碳管薄膜的厚度取决於奈米碳管陣列的高 度以及壓力大小。奈米碳管陣列的高度越大而施加的壓 力越小，則製備的奈米碳管薄膜的厚度越大；反之，奈 米碳管陣列的高度越小而施加的壓力越大，則製備的奈

G奈米~50奈 米。當該奈米碳管層中的奈米碳管爲多壁奈米碳管時， 該多壁奈米碳管的直徑爲1.5奈米〜50奈米。 [0036] 步驟三：提供至少兩個電極28，將上述至少兩個電極28 間隔設置並與奈米碳管層形成電連接，從而形成觸控面 板20。 [0037] 其中，所述奈米碳管層用作透明導電層24,所述電極28 可以採用濺射、電鍍、化學鍍等沈積方法直接形成在透 明導電層24上。另外，也可用銀膠等導電粘結劑將上述 的電極28粘結在透明導電層24上。本實施例中，上述至 1013075511-0 單編號A〇101 第13頁/共30頁 [0038][Technical Field] The present invention relates to a touch panel, a method of manufacturing the touch panel, and a display device using the touch panel, in particular The invention relates to a carbon nanotube-based touch panel, a method of manufacturing the touch panel, and a display device using the touch panel. [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 light-transmitting touch panels are mounted in front of display devices such as liquid crystals Gradually increase. The user of such an electronic device visually confirms the display content of the display device located on the back surface of the touch panel through the touch panel, and presses the touch panel to operate by means of a finger or a pen. Thereby, various functions of the electronic device can be operated. [0003] According to the working principle of the touch panel and the transmission medium, the touch panel of the prior art is divided into four types, namely, a resistive type, a capacitive type, an infrared type, and a surface acoustic wave type. Capacitive touch panels are widely used due to their high accuracy and strong anti-interference ability. [0004] Prior art capacitive touch panels (see "Research on Continuous Thin Film Capacitive Touch Panels", Li Shuben et al., Optoelectronics Technology, vol 15, p62 (1995)) include a glass substrate, a transparent conductive layer , and a plurality of metal electrodes. In the capacitive touch panel, the material of the glass substrate is nano-calcium glass. The transparent conductive layer is a transparent material such as indium tin oxide (IT0) or antimony tin oxide (ITO). The electrode is formed by printing a conductive metal (e.g., silver) having a low electrical resistance. The electrode spacing is set in transparent conductive 0961493#sole Α0101 Page 3 of 30 1013075511-0 1364860 Modified on February 29, 2011 Correction page corners of each layer. Further, the transparent conductive layer is coated with a passivation layer. The passivation layer is formed by a hardening or densification process of a liquid glass material, followed by heat treatment to form a passivation layer. [0005] When a touch object such as a finger touches the surface of the touch panel, a coupling capacitance is formed between the touch object such as a human body and a transparent conductive layer in the touch panel. For high-frequency currents, the capacitor is a direct conductor, and the touch of a finger or the like will draw a small current from the contact point. The current flows out from the electrodes on the touch panel, and the current flowing through the four electrodes is proportional to the distance from the finger to the four corners. The touch panel controller obtains a touch by accurately calculating the ratio of the four currents. The location of the point. [0006] Therefore, the transparent conductive layer is an essential component for the touch panel. In the prior art, the transparent conductive layer usually adopts an ITO layer. However, the ITO layer is currently mainly prepared by sputtering or evaporation, in the process of preparation, A higher vacuum environment and heating to 200 to 300 ° C are required, thus making the preparation of the ITO layer costly. In addition, the ΙΤ0 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 non-uniform distribution of the resistance value, which results in the problem that the capacitive touch panel of the prior art has low resolution and low precision of the touch panel. 0007] In view of the above, it is indeed necessary to provide a touch panel with high resolution, high precision and durability, and a method for preparing a touch panel with simple method and low cost, and a display device using the same. [0008] A touch panel comprising a substrate; a transparent conductive layer 1013075511-0 _49380 woven A () 1Q1 ^ 4 1 ^ 30 1 1, 364860 1 〇 1 year 〇 February 29 曰 nuclear replacement a transparent conductive layer disposed on a surface of the substrate; and at least two electrodes * the at least two electrodes are spaced apart and electrically connected to the transparent conductive layer, wherein the transparent conductive layer comprises a carbon nanotube layer The carbon nanotube layer comprises a plurality of carbon nanotubes that are isotropic or oriented in a fixed orientation or oriented in different directions. [0009] A method for preparing a touch panel, comprising the steps of: providing a carbon nanotube array and a substrate, wherein the carbon nanotube array is formed on a substrate; and extruding the carbon nanotube array to obtain a nanometer A carbon tube layer is formed on one surface of the substrate; and at least two electrodes are provided, and at least two electrodes are spaced apart and electrically connected to the carbon nanotube layer to form the touch panel. [0010] A display device includes a touch panel, the touch panel includes a substrate, a transparent conductive layer, the transparent conductive layer is disposed on a surface of the substrate, and at least two electrodes, the at least two electrodes Intersected and electrically connected to the transparent conductive layer; a display device that is disposed opposite to and adjacent to the base of the touch panel. Wherein, the transparent conductive layer comprises a carbon nanotube layer comprising a plurality of carbon nanotubes which are isotropic or oriented in a fixed direction or in different directions. [0011] Compared with the prior art, the touch panel, the touch panel manufacturing method and the display device provided by the technical solution have the following advantages: First, since the carbon nanotube passes through the carbon nanotube layer Van der Waals forces are attracted to each other and closely combine to form a self-supporting structure composed of a plurality of carbon nanotubes, so that the above-mentioned carbon nanotube layer has good mechanical strength and toughness, so the above-mentioned carbon nanotubes are used. The layer is made of a transparent conductive layer, which can improve the durability of the touch panel, thereby improving the use of the touch surface 1013075511-0 09614938#单号A〇101 Page 5 of 30 pages 1364860 February 29, 2011 The durability of the display device that is replacing the k-board. Second, the carbon nanotube layer comprises a plurality of carbon nanotubes that are isotropic or oriented in a fixed orientation or oriented in different directions. Therefore, using the above-mentioned carbon nanotube layer as a transparent conductive layer can make the transparent conductive layer have a uniform resistance distribution and good light transmission characteristics, thereby improving the resolution of the touch panel and the display device using the touch panel. Rate and accuracy. Thirdly, since the carbon nanotube layer is obtained by extruding a carbon nanotube array through a pressure applying device, the preparation method is simple, and the method does not require a vacuum environment and a heating process, so the nano carbon layer prepared by the above method is used. The transparent conductive layer is advantageous for reducing the cost of the touch panel and the display device using the touch panel. [Embodiment] The present technical solution will be further described in detail with reference to the accompanying drawings. Referring to FIGS. 1 and 2, the touch panel 20 includes a substrate 22, a transparent conductive layer 24, a protective layer 26, and at least two electrodes 28. The base 22 has a first surface 221 and a second surface 222 opposite the first surface 221. The transparent conductive layer 24 is disposed on the first surface 221 of the substrate 22; the at least two electrodes 28 are respectively disposed at or at each corner of the transparent conductive layer 24, and are electrically connected with the transparent conductive layer 24 for An equipotential surface is formed on the transparent conductive layer 24. The protective layer 26 can be disposed directly on the transparent conductive layer 24 and the electrode 28. [0014] The base 22 is a curved or planar structure.

In this embodiment, the method for preparing a super-sequential carbon nanotube array adopts a chemical vapor deposition method. The specific steps include: (a) providing a flat substrate, the substrate may be selected from a P-type or N-type germanium substrate, or A sand substrate having an oxide layer formed thereon, preferably a 4-inch germanium substrate is used in the embodiment; (b) a catalyst layer is uniformly formed on the surface of the substrate, and the catalyst layer material may be iron (Fe), uranium (Co) or nickel ( Ni) or any combination of alloys 1 C c _ 御卢单号 A0101 Page 9 / Total 30 pages 1〇13〇75511~〇1364860 __ February 29, 2010 Nuclear replacement page) The above formed catalyst The substrate of the layer is annealed in air oxygen at 700 to 900 ° C for about 30 minutes to 90 minutes; (d) the treated substrate is placed in a reaction furnace, heated to 500 to 740 ° C in a protective gas atmosphere, and then passed through The carbon source gas is reacted for about 5 to 30 minutes to grow to obtain a super-sequential carbon nanotube array having a height of 200 to 400 μm. The super-sequential carbon nanotube array is a pure carbon nanotube array formed by a plurality of carbon nanotubes that are parallel to each other and grown perpendicular to the substrate. The super-sequential carbon nanotube array is substantially free of impurities such as amorphous carbon or residual catalyst metal particles by the above controlled growth conditions. The carbon nanotubes in the array of carbon nanotubes form an array by close contact with van der Waals forces. The carbon nanotube array is substantially the same area as the above substrate.

[0028] Further, in the embodiment, the substrate 22 is a rectangular glass substrate, and the substrate 22 has substantially the same area as the carbon nanotube array; wherein the substrate 22 has a first surface 221 and is opposite to the first surface 221 The second surface 222 ° [0029] Step 2: Extrusion of the above carbon nanotube array to obtain a carbon nanotube layer formed on the surface of the substrate 22. 〇96_梦单号A0101 Page 10/Total 30 Page 1013075511-0 1364860 101. February 29th Revision Replacement [0030] Specifically, the carbon nanotube layer comprises a carbon nanotube film . Wherein, since the carbon nanotube provided by the technical solution has good viscosity, the above-mentioned substrate 22 can be relatively firmly adhered to the carbon nanotube array. Therefore, the above-described carbon nanotube array is extruded to obtain a carbon nanotube layer formed on one surface of the substrate 22, which includes the following two methods. Firstly, an application device is provided to apply a certain pressure to the carbon nanotube array; under the action of pressure, the carbon nanotube array is separated from the grown substrate to form a self-supporting structure composed of a plurality of carbon nanotubes. The carbon nanotube film is thereafter bonded to the first surface 221 of the substrate 22 by a conductive adhesive such as a conductive silver paste or the like. Secondly, the first surface 221 of the substrate 22 is directly covered on the carbon nanotube array; an application device is applied to apply a certain pressure to the second surface 222 of the substrate; and the carbon nanotube array is under pressure The grown substrate is separated to form a carbon nanotube film having a self-supporting structure composed of a plurality of carbon nanotubes adhered to the first surface 221 of the substrate 22. [0031] In addition, during the pressing process, the carbon nanotube array is separated from the grown substrate by pressure, thereby forming a carbon nanotube film having a self-supporting structure composed of a plurality of carbon nanotubes. And the plurality of carbon nanotubes are substantially parallel to the surface of the carbon nanotube film. In the embodiment of the technical solution, the pressing device is an indenter, the surface of the indenter is smooth, and the shape and extrusion direction of the indenter determine the arrangement and manner of the carbon nanotubes in the prepared carbon nanotube film. Specifically, when the planar indenter is pressed in a direction perpendicular to the substrate grown by the carbon nanotube array, the carbon nanotube film is isotropically aligned (see FIG. 4); When the roller-shaped indenter is pressed in a certain fixed direction, the carbon nanotube can be obtained along the fixed 09614938# single number A〇101 page 11/total 30 page 1013075511-0 1364860 [ιοί年02月29 The modified carbon nanotube film arranged in the direction of the direction of the ^ (see Figure 5); when the roller-shaped indenter is pressed in different directions, the carbon nanotubes aligned in different directions can be obtained. film. [0032] It can be understood that when the above-mentioned carbon nanotube array is extruded in the above different manner, the carbon nanotubes are poured under the action of pressure and are attracted to each other by adjacent vanadium tubes through the van der Waals force. And connecting to form a carbon nanotube film having a self-supporting structure composed of a plurality of nano carbon members. The plurality of carbon nanotubes are substantially parallel to the surface of the carbon nanotube film and are oriented isotropic or oriented in a fixed direction or in different directions. In addition, under the action of waste force, the carbon nanotube array is separated from the grown substrate, so that the carbon nanotube film is easily detached from the substrate. It should be understood by those skilled in the art that the degree of tilting (inclination) of the above-mentioned nanocarbon # array is related to the magnitude of the pressure, and the greater the pressure, the larger the inclination angle. The thickness of the prepared carbon nanotube film depends on the height of the carbon nanotube array and the pressure. The higher the height of the carbon nanotube array and the lower the applied pressure, the greater the thickness of the prepared carbon nanotube film; conversely, the smaller the height of the carbon nanotube array and the higher the applied pressure, the prepared The smaller the thickness of the nano-carbon thinner, the smaller the diameter of the carbon nanotubes in the carbon nanotube film of the present embodiment is at an angle α with the surface of the carbon nanotube film, wherein α is greater than or equal to zero degrees and less than or equal to 15 degrees. . It is understood that the conductivity of the carbon nanotube film is related to the above-mentioned loss angle. Specifically, the smaller the angle, the better the electrical conductivity of the prepared carbon nanotube film. Conversely, the larger the angle, the lower the conductivity of the prepared carbon nanotube film. [〇〇34] Further, the above-mentioned carbon nanotube layer can be verified in the second step of the present embodiment, 09614938#单号Α〇101, page 12/total 30 page 1013075511-0 1.364860, February 29, 101 A carbon nanotube film prepared by a hundred or a plurality of carbon nanotube films arranged in an overlapping manner. Specifically, the carbon nanotube film may be further coated on another carbon nanotube array, and the carbon nanotube covered with the carbon nanotube film is extruded by the pressing device provided in step 2 of the embodiment of the present technical solution. The array forms a double-layered carbon nanotube film, and the carbon nanotube films in the double-layered carbon nanotube film are tightly bonded by van der Waals force. By repeating the above steps, a carbon nanotube layer containing a multilayered carbon nanotube film can be obtained. [0035] In this embodiment, the width and length of the carbon nanotube film are related to the size of the substrate on which the carbon nanotube array is grown, and the width and length of the carbon nanotube film are not limited, and may be according to actual needs. be made of. In the embodiment of the technical solution, a 4-inch substrate growth super-sequential carbon nanotube array is used. The thickness of the carbon nanotube layer is from 0.5 nm to 100 μm. When the carbon nanotubes in the carbon nanotube layer are single-walled carbon nanotubes, the diameter of the single-walled carbon nanotubes is from 0.5 nm to 50 nm. When the carbon nanotubes in the carbon nanotube layer are double-walled carbon nanotubes, the double-walled carbon nanotubes have a diameter of 1. G nanometers to 50 nanometers. When the carbon nanotubes in the carbon nanotube layer are multi-walled carbon nanotubes, the multi-walled carbon nanotubes have a diameter of 1.5 nm to 50 nm.

The touch panel controller 40, the central processing unit 50, and the display device controller 60 are connected by a circuit, the touch panel controller 40 is connected to the electrode 28 of the touch panel 20, and the display device controller 60 is connected to the display device. 30. [0047] The principle of the touch panel 20 and the display device 100 in this embodiment is as follows: The touch panel 20 can be directly disposed on the display surface of the display device 30 when applied. The touch panel controller 40 positions the selection information input based on an icon or menu position touched by the touch object 70 such as a finger, and transmits the information to the central processing unit 50. The central processing unit 50 controls the display of the display device 30 via the display controller 60. [0048] Specifically, a predetermined voltage is applied to the transparent conductive layer 24 when in use. A voltage is applied to the transparent conductive layer 24 through the electrode 28 to form an equipotential surface on the transparent conductive layer 24. The user visually confirms the display of the display device 30 disposed behind the touch panel 20, and when the user touches or approaches the protective layer 26 of the touch panel 20 by a touch object 70 such as a finger or a pen, the touch object 70 and the transparent conductive layer are operated. A coupling capacitor is formed between 24. For high frequency currents, the capacitor is a direct conductor, so the finger draws a portion of the current from the contact point. The current flows from the electrodes on the touch panel 20, respectively, and the current flowing through the four electrodes is proportional to the distance from the finger to the four corners. The touch panel controller 40 obtains an accurate calculation of the ratio of the four currents. The location of the touch point. After that, the touch panel controller 40 transmits the digitized touch position data to the central processing unit 50 493# single number A 〇 101 page 16 / total 30 pages 1013075511-0 1364860 [ιοί年. 〇 2 months after the replacement i . Then, the central processing unit 50 accepts the above-described touch position data and executes it. Finally, the central processing unit 50 transmits the touch position data to the display controller 6A, thereby displaying the touch information issued by the touch object 7 on the display device 30.
