Abstract
Description
本發明涉及一種觸控裝置，尤其涉及一種三維觸控裝置。The present invention relates to a touch device, and more particularly to a three-dimensional touch device.
近年來，伴隨著移動電話與觸摸導航系統等各種電子設備的高性能化和多樣化的發展，在液晶等顯示設備的前面安裝透光性的觸控面板的觸控式電子設備逐步增加。這樣的觸控式電子設備的使用者通過觸控面板，一邊對位於觸控面板背面的顯示設備的顯示內容進行視覺確認，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。In recent years, with the development of high performance and diversification of various electronic devices such as mobile phones and touch navigation systems, touch electronic devices in which a translucent touch panel is mounted on the front surface of a display device such as a liquid crystal are gradually increasing. The user of such a touch-sensitive 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 using a finger or a pen. Thereby, various functions of the electronic device can be operated.
按照觸控面板的工作原理和傳輸介質的不同，現有的觸控面板分為四種類型，分別為電阻式、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、抗干擾能力強而應用較為廣泛。According to the working principle of the touch panel and the transmission medium, the existing touch panels are divided into four types, namely, resistive, capacitive, infrared, and surface acoustic wave. Among them, the capacitive touch panel is widely used due to its high accuracy and strong anti-interference ability.
先前技術中的電容型觸控面板包括一玻璃基板，一透明導電層，以及複數金屬電極。在該電容型觸控面板中，玻璃基板的材料為納鈣玻璃。透明導電層為例如銦錫氧化物（ITO）或銻錫氧化物（ATO）等透明材料。電極為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。The capacitive touch panel of the prior art includes 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 (ITO) or antimony tin oxide (ATO). The electrode is formed by printing a conductive metal (for example, silver) having a low electrical resistance. The electrode spacing is disposed at each corner of the transparent conductive layer. Further, the transparent conductive layer is coated with a passivation layer. The passivation layer is formed by a hardening or densification process of the liquid glass material, followed by heat treatment.
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，電容是直接導體，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。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 finger and a transparent conductive layer in the touch panel due to a human body electric field. For high-frequency currents, the capacitor is a direct conductor, and the touch of a finger or the like picks up 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.

步驟二：採用一拉伸工具從奈米碳管陣列中拉取奈米碳管獲得一奈米碳管拉膜。Step 2: Pulling a carbon nanotube from the carbon nanotube array using a stretching tool to obtain a carbon nanotube film.
該奈米碳管拉膜的製備具體包括以下步驟：（a）從上述奈米碳管陣列中選定一定寬度的複數奈米碳管片斷，本實施例優選為採用具有一定寬度的膠帶接觸奈米碳管陣列以選定一定寬度的複數奈米碳管束；（b）以一定速度沿基本垂直於奈米碳管陣列生長方向拉伸複數該奈米碳管束，以形成一連續的奈米碳管拉膜。The preparation of the carbon nanotube film comprises the following steps: (a) selecting a plurality of carbon nanotube segments of a certain width from the carbon nanotube array, and the embodiment preferably uses a tape having a certain width to contact the nanometer. The carbon tube array selects a plurality of carbon nanotube bundles of a certain width; (b) stretching the plurality of carbon nanotube bundles at a constant speed along a growth direction substantially perpendicular to the carbon nanotube array growth direction to form a continuous carbon nanotube bundle membrane.
在上述拉伸過程中，該複數奈米碳管束在拉力作用下沿拉伸方向逐漸脫離基底的同時，由於凡得瓦力作用，該選定的複數奈米碳管束分別與其他奈米碳管束首尾相連地連續地被拉出，從而形成一奈米碳管拉膜。該奈米碳管拉膜包括複數首尾相連且定向排列的奈米碳管束。該奈米碳管帶狀膜中的奈米碳管的排列方向基本平行於奈米碳管拉膜的拉伸方向。During the above stretching process, the plurality of carbon nanotube bundles are gradually separated from the substrate in the stretching direction under the action of the tensile force, and the selected plurality of carbon nanotube bundles and the other carbon nanotube bundles are respectively end-to-end due to the effect of the van der Waals force.

The arrangement of the carbon nanotubes in the carbon nanotube film is substantially parallel to the stretching direction of the carbon nanotube film.
通過上述直接拉取獲得的擇優取向的奈米碳管拉膜比無序的奈米碳管薄膜具有更好的均勻性，即具有更均勻的厚度以及具有更均勻的導電性能。同時該直接拉伸獲得奈米碳管拉膜的方法簡單快速，適宜進行工業化應用。The preferentially oriented carbon nanotube film obtained by the above direct drawing has better uniformity than the disordered carbon nanotube film, that is, has a more uniform thickness and has more uniform electrical conductivity. At the same time, the direct stretching method for obtaining the carbon nanotube film is simple and rapid, and is suitable for industrial application.

The plurality of electrodes may be directly formed on the first transparent conductive layer 112 by a deposition method such as sputtering, electroplating, or electroless plating. Alternatively, the plurality of electrodes may be bonded to the first transparent conductive layer 112 by a conductive adhesive such as silver paste.
