201122630 六、發明說明: 【發明所屬之技術領域】 [0001]本發明涉及一種觸摸屏及顯示裝置,尤其涉及一種採用 奈米碳管的觸摸屏及使用該觸摸屏的顯示裝置。 【先前技#亍】 [〇〇〇2]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,在液晶等顯示器的前面 安裝透光性的觸摸屏的電子設備逐步增加。這樣的電子 設備的利用者通過觸摸屏,一邊對位於觸摸屏背面的顯 不器的顯示内容進行視覺確認,一邊利用手指或筆等按 壓觸摸屏來進行操作。由此,可以操作電子設備的各種 功能。 [0003] 按照觸摸屏的工作原理和傳输介質的不同,先前的觸摸 屏分為四種類型,分別為電阻式、電容式、紅外線式以 及表面聲波式。其中電阻式觸摸屏及電容式觸摸屏的應 用比較廣泛(K. Noda,K. Tanimura,Electronics and Communications in Japan, Part 2, Vol. 84’ No· 7’ P40 (2001 );李樹本,王清弟,吉建華, 光電子技術,Vol. 15,P62 (1995))。 [0004] 先前的觸摸屏一般包括一第一基板,該第一基板的第一 表面形成有一第一透明導電層;一第二基板,該第二基 板的第二表面形成有一第二透明導電層;該第一透明導 電層與該第二透明導電層相對設置;以及多個點狀隔離 物(Dot Spacer),該多個點狀隔離物設置在第一透明導 電層與第二透明導電層之間。其中,所述第一透明導電 098145169 表單編號A0101 第4頁/共31頁 0982077214-0 201122630 層與第二透明導電層通常採用具有導電特性的銦錫氧化 物(Indium Tin Oxide, ΙΤ0)層(下稱ΙΤ0層)。當使用 手指或筆按壓第一基板時,第一基板發生扭曲,使得按 壓處的第一透明導電層與第二透明導電層彼此接觸。通 過外接的電子電路分別向第一透明導電層與第二透明導 電層依次施加電壓,電子電路能夠檢測出被按壓的位置 。進一步地,電子電路可根據檢測的被按壓位置啟動電 子設備的各種功能切換。 [0005] 然而,ΙΤ0層作為透明導電層具有機械和化學耐用性不夠 好等缺點,且存在電阻不均勻且電阻值範圍較小的現象 。從而導致先前的觸摸屏存在耐用性差、靈敏度低及準 確性較差等缺點。因此,提高透明導電層的耐用性及導 電性能,將有利於提高觸摸屏的耐用性、靈敏度及精確 度。 【發明内容】 丨 [0006] 有鑒於此,確有必要提供一種精確度高、靈敏度高及耐 用性好的觸摸屏,以及使用該觸摸屏的顯示裝置。 [0007] —種觸摸屏,該觸摸屏包括一第一電極板,該第一:電極

第5頁/共31頁 0982077214-0 201122630 中的至少一個透明導電層為一奈米碳管層,該奈米碳管 層由複數奈米碳管組成,且該複數奈米碳管沿同—方向 擇優取向排列;所述第一電極板與第二電極板之間設置 一透明絕緣體,該透明絕緣體的折射率大於真空的折射 [0008] [0009] [0010] 一種顯示裝置,該顯示裝置包括一顯示器以及設置在所 述顯示器面向使用者一侧的觸摸屏,其中,該觸摸屏為 上述結構。 與先前技術相比較,本發明提供的觸摸屏及顯示裝置具 有以下優點:第一,奈米碳管具有優異的力學特性使得 奈米奴管層具有良好的韌性及機械強度,且耐彎折,故 採用奈米碳管層作為透明導+ 電層,可以相應的提高觸摸 屏的耐用性;進而提高使用該觸摸屏的顯示裝置的耐用 性;第二,由於奈米碳管層包括多個均勻分佈的奈米碳 管,且奈米碳管具有優異的導電性,故,择用該奈米碳 管層也具有優異的導電性,均勻的阻值分佈,因此,採 用該奈米碳管層料透明導電料以相應的提高觸摸屏 的靈敏度及精確度,進而提高應用該觸摸屏的顯示裝置 的靈敏度和精確度。 【實施方式】 下面將結。關及具體實施例’對本制提供的觸摸屏 以及使用該職屏的顯*裝置作進-步的詳細說明。 [0011] 098145169

所述第一基板120為透明的直具有—定柔軟度的薄膜或薄 板。所述第一基板120的材料為塑膠或樹腊等柔性材料。 所述第二基板140為透明基板。所述第二基板140的材料 可以為玻璃、石英、金剛石等硬性材料,也可以為塑膠 及樹脂等柔性材料。具體地,所述柔性材料包括聚碳酸 酯(PC)、聚甲基丙稀酸曱酯(PMMA)、聚對苯二甲酸乙二 醇酯(PET)等聚酯材料,聚醚颯(PES)、纖維素酯、聚氣 乙烯(PVC)、笨並環丁烯(BCB)及丙烯酸樹脂等材料。所 述第一基板120和第二基板140的厚度分別為1毫米〜1釐 米。本實施例中,所述第一基板120與第二基板丨4〇的材 料均為PET,厚度均為2毫米。可以理解,形成所述第一 基板120的材料並不限於上述列舉的材料,只要能使第一 基板120起到支撐的作用,並具有一定柔性及較好的透明 度即可。形成所述第二基板丨4〇的材料並不限於上述列舉 098145169 表單編號A0101 第8頁/共31頁 0982077214-0 201122630 [0016] Ο [0017] Ο [0018] 的材料,只要能使第二基板140起到支撐的作用,並具有 一定的透明度即可。 所述第一黏膠層128的作用是使所述第一透明導電層122 黏附於所述第一基板120的第一表面1 202。所述第二黏膠 層148的作用是使所述第二透明導電層142黏附於所述第 二基板140的第二表面1404。所述第一黏膠層128與第二 黏膠層148的折射率的範圍為1. 30~1. 80。所述第一黏膠 層128與第二黏膠層148的材料為熱塑膠或UV (Ultraviolet Rays) 膠, 如聚曱基丙烯酸甲酯 、聚氣乙烯等 。本實施例中,所述第一黏膠層128與第二黏膠層148的 材料相同,均為聚甲基丙烯酸甲酯,且其折射率的範圍 為1.45~1.53 。 所述第一透明導電層122及第二透明導電層142均具有導 電且透明的特性,該第一透明導電層122及第二透明導電 層142均為一奈米碳管層,該奈米碳管層為複數奈米碳管 ; 丨; ,且該複數奈米碳管沿同一方向擇優取向排列。其中, 所述奈米碳管層包括至少一個奈米碳管膜。當所述奈米 碳管層包括多個奈米碳管膜時,該奈米碳管膜可以平行 且無間隙共面設置或層疊設置,且該多個奈米碳管膜中 的奈米碳管基本沿同一方向擇優取向排列,即相鄰的奈 米碳管膜中的奈米碳管的排列方向基本一致。 請參閱圖3,所述奈米碳管膜是由複數奈米碳管組成的自 支撐結構。所述複數奈米碳管為沿同一方向擇優取向排 列。所述擇優取向是指在奈米碳管膜中大多數奈米碳管 的整體延伸方向基本朝同一方向。而且,所述大多數奈 098145169 表單編號A0101 第9頁/共31頁 0982077214-0 201122630 米碳管的整體延伸方向基本平行於奈米碳管膜的表面。 進一步地,所述奈米碳管膜中多數奈米碳管是通過凡德 瓦爾力首尾相連。具體地,所述奈米碳管膜中基本朝同 一方向延伸的大多數奈米碳管中每一奈米碳管與在延伸 方向上相鄰的奈米碳管通過凡德瓦爾力首尾相連。當然 ,所述奈米碳管膜中存在少數隨機排列的奈米碳管,這 些奈米礙管不會對奈米破管膜中大多數奈米碳管的整體 取向排列構成明顯影響。所述自支撐為奈米碳管膜不需 要大面積的載體支撐,而只要相對兩邊提供支撐力即能 整體上懸空而保持自身膜狀狀態,即將該奈米碳管膜置 於(或固定於)間隔一定距離設置的兩個支撐體上時, 位於兩個支撐體之間的奈米碳管膜能夠懸空保持自身膜 狀狀態。所述自支撐主要通過奈米碳管膜中連續的,通 過凡德瓦爾力首尾相連延伸排列的奈米碳管而實現。 [0019] 具體地,所述奈米碳管膜中基本朝同一方向延伸的多數 奈米碳管,並非絕對的直線狀,可以適當的彎曲;或者 並非完全按照延伸方向上排列,可以適當的偏離延伸方 向。因此,不能排除奈米碳管膜的基本朝同一方向延伸 的多數奈米碳管中並列的奈米碳管之間可能存在部分接 觸。 [0020] 具體地,所述奈米碳管膜包括多個連續且定向排列的奈 米碳管片段。該多個奈米碳管片段通過凡德瓦爾力首尾 相連。每一奈米碳管片段包括多個相互平行的奈米碳管 ,該多個相互平行的奈米碳管通過凡德瓦爾力緊密結合 。該奈米碳管片段具有任意的長度、厚度、均勻性及形 098145169 表單編號A0101 第10頁/共31頁 0982077214-0 201122630 狀。該奈求碳管膜中的奈米碳管沿同一方向擇優取向排 列。 [0021] ❹ 所述奈米碳管拉膜可藉由從奈米碳管陣列直接拉取獲得 。可以理解,藉由將複數個奈米碳管拉膜平行且無間隙 共面鋪設或/和層疊鋪設,可以製備不同面積與厚度之奈 米碳管結構。當奈米碳管結構包括複數個層疊設置的奈 米碳管拉膜時,相鄰的奈米碳管拉膜中的奈米碳管之排 列方向形成一夾角α,0° S α €90°。所述奈米碳管膜的 結構請參見於2008年8月16日公開的第200833862號中 華民國公開專利申請公佈本。由於該奈米碳管膜中的奈 米碳管具有很好的柔韌性,使得該奈米碳管膜具有很好 的柔韌性,可以彎曲折疊成任意形狀而不易破裂;因此 ,所述奈米碳管層也具有較好的柔韌性,從而使得採用 該奈米碳管層作透明導電層的觸摸屏10具有較好的耐用 性,進而使得使用該觸摸屏10的顯示裝置具有較好的耐 用性。 Ο [0022] 該奈米碳管層中的奈米碳管包括單壁奈米碳管、雙壁奈 米礙管及多壁奈米碳管中的一種或多種。所述單壁奈米 碳管的直徑為0. 5奈米〜50奈米,雙壁奈米碳管的直徑為 1.0奈米~50奈米,多壁奈米礙管的直徑為1.5奈米~50奈 米。所述奈米碳管的長度大於50微米。優選地,該奈米 碳管的長度優選為200微米~900微米。 可以理解,所述第一透明導電層122及第二透明導電層 142中的一個透明導電層可以為所述奈米碳管層,另一個 透明導電層可以為ΙΤΟ、ΑΤΟ等其他透明可導電的材料。 098145169 表單編號Α0101 第11頁/共31頁 0982077214-0 [0023] 201122630 [0024] 所述第一電極124與所述第二電極144的材料為金屬、奈 米碳管或其他導電材料,只要確保該第一電極124與該第 二電極144能導電即可。本實施例中,該第一電極124與 第二電極144的材料為銀。可以理解,用於柔性觸摸屏的 上述電極還應具有一定的韌性和易彎折度。 [0025] 所述透明絕緣體15填充於所述第一透明導電層122與所述 第二透明導電層142之間,並與該第一透明導電層122及 第二透明導電層142接觸,且使得該第一透明導電層122 與該第二透明導電層142電絕緣。所述透明絕緣體15可以 保證其在受到按壓時,可以使該第一透明導電層122與所 述第二透明導電層142電連接;當受到按壓之後,所述透 明絕緣體15能夠保證該第一透明導電層122與第二透明導 電層142電絕緣。其中,請參閱圖5,由於所述第二透明 導電層142為奈米碳管層,該奈米碳管層包括複數奈米碳 管1422,該複數奈米碳管1422之間具有一定的間隙。當 該第二透明導電層142通過所述第二黏膠層148黏附於所 述第二基板140時,由於該第二黏膠層148具有一定的黏 性,所以該黏膠就會填充於所述複數奈米碳管1422之間 的間隙中,並形成突起1482 ;所述透明絕緣體15填充於 所述複數奈米碳管1422之間的間隙中,並與所述突起 1482接觸。另外,還由於奈米碳管具有吸光的特點,所 述光束從奈米碳管之間的間隙中射出,所以,所述光束 從第二基板140經過所述第二黏膠層148射到所述透明絕 緣體15之後才能射出。 [0026] 圖4為所述觸摸屏中沒有圖2中的透明絕緣體15時,光束 098145169 表單編號A0101 第12頁/共31頁 0982077214-0 201122630 Ο 經過第二透明導電層142與第二黏隳層時的光路放大 示意圖。由於該第二黏膠層148具有〆定的黏性’其會攀 攸到所述奈米礙管1422的表面,所以填充於所述奈米碳 管1422之間的間隙中的黏膠會形成突起I482。一部分複 合光束直接通過所述第二黏膠層148時會經過所述突起 1482,由於所述第二黏膠層148的材料的折射率與真空的 折射率相差較大’該突起1482相當於光學三棱鏡,因此 ,複合光束經過所述突起1482時會產生色散現象。即, 由於複合光束包括多個不同波長的單色光,•該多個單 色光在該第二黏膠層148中的折射率不柯’故該多個單色 光從該第二黏膠層148射出時的折射,角也不同,從而使得 該部分複合光束從該第二電極板14射出時為多個分散的 單色光。另一部分複合光束通過所述第;黏膠層148的相 鄰突起1482之間的平坦部分以複合光的形.式從5玄第二電 極板14射出。 ;; [0027] ❹ . ^ : 由此可見,從所述第二電極板14射向第-電極板12的光 —部分為複合光,另一部分為單色光。所述第一電極板 12的結構及材料與所述第二電極板14的結構及材料相同 ’所以,所述第一電極板12中的第一透明導電層122中也 會有第一黏膠層128形成的突起。當所述第一電極板12與 第二電極板14之間沒有透明絕緣體15時,所述複合光經 過所述第一黏膠層128的突起時也會發生色散現象,從所 述第-基板120射出多個分散的單色^。當所述複合光經 過所述第一黏膠層128的相鄰突起之間的平坦部分時,仍 會从複合光從所述第_基板12Q射出。所述單色光經過所 098145169 表單編號A0101 第13頁/共31頁 0982077214-0 201122630 述第一黏膠層128時,不會發生色散,其仍以單色光從所 述第一基板120射出。 [0028] 當從第一基板120射出的多個分散的單色光進入到使用者 的視線時,使用者就會看到所述觸摸屏出現彩色條紋, 從而影響觸摸屏的解析度。 [0029] 為了使複合光束經過所述突起1482時不產生色散現象, 所述透明絕緣體15的材料與所述第二黏膠層148及第一黏 膠層128的材料有關。具體地,所述透明絕緣體15的材料 根據所述第二黏膠層148及第一黏膠層128的折射率選擇 ,該透明絕緣體15的折射率與所述第二黏膠層148及第一 黏膠層128的折射率越接近越好。由於本發明實施例中的 第二黏膠層148及第一黏膠層128的折射率在1. 30〜1. 80 之間,因此,所述透明絕緣體的折射率越接近 1. 30~1. 80越好。本實施例中,由於所述第二黏膠層148 及第一黏膠層128的折射率為1. 45〜1. 53,因此,所述透 明絕緣體15選擇為折射率為1. 48的松油醇較好,其折射 率比較接近第二黏膠層148及第一黏膠層128的折射率。 [0030] 所述透明絕緣體15的材料不限於為松油醇,其折射率大 於真空的折射率即可;這是因為當所述透明絕緣體15的 折射率大於真空的折射率時,複合光束從所述突起1482 射向所述透明絕緣體15時的折射角小於圖4中複合光束從 所述突起1482射向真空時的折射角,因此,當所述透明 絕緣體15的折射率大於真空的折射率時,所述突起1482 對複合光束起的色散作用相對於圖4中的色散作用較弱。 具體地,該可以透明絕緣體15的材料可以為聚乙烯、聚 098145169 表單編號A0101 第14頁/共31頁 0982077214-0 201122630 Ο [0031] 氯乙烯、聚苯乙烯、聚曱基丙烯酸曱酯、純淨水、松油 醇、丙醇、甲醇、乙醇、乙趟、四氯化碳、白油、松節 油、撖禮油、丙酮、二硫化碳、甘油或三氯甲烧等。所 述透明絕緣體15的形態不限,其可以為液態或固態。由 於液體具有一定的流動性,有利於在其受到按壓時能夠 迅速從按壓處向非按壓區域流動,實現第一透明導電層 122與第二透明導電層142電連接;且在按壓後,能夠迅 速從非按壓區回到剛才的按壓處,使得按壓處可以重新 實現按壓前的第一透明導電層122與第二透明導電層142 的電絕緣;有利於提高觸摸屏10的靈敏度,因此,該透 明絕緣體15優選為液態。 Ο 可以理解,當所述透明絕緣體15為固態時,其為軟質的 透明絕緣膜,該透明絕緣膜在壓力的作用下會發生形變 、密度減小,可以實現所述第一透明導電層122和第二透 明導電層142的電連接,且當該透明絕緣膦失去壓力的作 用後,其能夠回復至受到壓力前的狀態,即重新使得所 述第一透明導電層122和第二透明導電層142電絕緣。當 所述透明絕緣體15為液態時,由於液體具有一定的流動 性,其通過注射或塗覆等方式填充於所述第一透明導電 層122、第二透明導電層142以及絕緣框架18形成的封閉 空間中。 [0032] 可以理解,當所述第一透明導電層122及第二透明導電層 142中的一個透明導電層不是奈米碳管層,而是其他材料 層時,如,當所述第一透明導電層122為不是奈米碳管層 ,第二透明導電層142為奈米碳管層時,所述透明絕緣體 098145169 表單編號Α0101 第15頁/共31頁 0982077214-0 201122630 15的材料只根據所述第二黏膠層148的折射率選擇,無需 根據第一黏膠層128的折射率選擇。 [0033] 凊參閱圖5,光束從第二基板14〇需要經過所述透明絕緣 體15才忐射向所述第一電極板丨2。由於所述透明絕緣體 15的折射率與所述第二黏膠層148的折射率接近或相同, 即,所述透明絕緣體15的折射率與所述突起1482的折射 率接近或相同;當光束從所述突起1482射向所述透明絕 緣體15時的折射角非常小或幾乎等於零,故該突起 1482對複合光束的色散作用非常小或基本上不使複合光 束發生色散。這也就是說’射向第一電極板12的光中大 部分為複合光束,只有一少部分為單色光或幾乎沒有單 色光。 [0034] 射向所述第一電極板12中的光依次經過所述第一黏膠層 128、第一基板120才能射出所述觸摸屏1〇,被使用者看 到。由於第一電極板12的結構與所述第二電極板丨4的結 構相同,所以所述太秤分的複合光束從所述第一電極板 12射出,只有一少部分或幾乎沒有單色光從該第一電極 板12射出;因此,使用者在使用觸摸屏ι〇時,看到的彩 色條紋比較弱,或幾乎看不到彩色條紋,進而使得觸摸 屏10的解析度比較高。 [0035] 故,所述透明絕緣體15具有消除或減弱觸摸屏的彩色條 紋,提高觸摸屏的解析度的作用。 [0036] 所述多個點狀隔離物16設置在第二電極板14的第二透明 導電層142上’且該多個點狀隔離物16彼此間隔設置。所 098145169 表單編號A0101 第16頁/共31頁 0982077214-0 201122630 述絕 緣框架18設置於所述第一電極板12’的第—表面1

極板12與第二電極板14電絕緣即可。 〇 [0038] 所述屏蔽層146設置於所述第二基板ho的第_表面14〇2 。該屏蔽層146是為了減小由顯示器產生的電磁干擾,避 免從觸摸屏10發出的信號產生錯誤。該屏蔽層ι46可由奈 米碳管、導電聚合物等導電材料形成。本實施例中,所 述的屏蔽層146為由奈米碳管組成的奈米碳管膜,該屏蔽 層146作為電接地點,起到遮罩的作用’從而使得觸摸屏

Description of the Invention: [Technical Field] The present invention relates to a touch screen and a display device, and more particularly to a touch screen using a carbon nanotube and a display device using the same. [Previous technology #亍] [〇〇〇2] In recent years, with the development of high performance and diversification of various electronic devices such as mobile phones and touch navigation systems, a translucent touch panel is mounted in front of a display such as a liquid crystal. Electronic equipment has gradually increased. The user of such an electronic device operates by pressing the touch panel with a finger or a pen or the like while visually checking the display content of the display 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 previous touch screens are divided into four types, namely, resistive, capacitive, infrared, and surface acoustic waves. Among them, resistive touch screens and capacitive touch screens are widely used (K. Noda, K. Tanimura, Electronics and Communications in Japan, Part 2, Vol. 84’ No· 7’ P40 (2001); Li Shuben, Wang Qingdi, Ji Jianhua, Optoelectronic Technology, Vol. 15, P62 (1995)). [0004] The prior touch screen generally includes a first substrate, the first surface of the first substrate is formed with a first transparent conductive layer; a second substrate, the second surface of the second substrate is formed with a second transparent conductive layer; The first transparent conductive layer is disposed opposite to the second transparent conductive layer; and a plurality of dot spacers disposed between the first transparent conductive layer and the second transparent conductive layer . Wherein, the first transparent conductive 098145169 Form No. A0101 Page 4 / Total 31 page 0982077214-0 201122630 The layer and the second transparent conductive layer usually adopt an indium tin oxide (Indium Tin Oxide, ΙΤ0) layer with conductive properties (below 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 contact each other. A 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] However, the ΙΤ0 layer has disadvantages such as insufficient mechanical and chemical durability as a transparent conductive layer, and there is a phenomenon in which the resistance is uneven and the resistance value range is small. As a result, previous touch screens have disadvantages such as poor durability, low sensitivity, and poor accuracy. Therefore, improving the durability and electrical conductivity of the transparent conductive layer will help to improve the durability, sensitivity and accuracy of the touch screen. SUMMARY OF THE INVENTION [0006] In view of the above, it is indeed necessary to provide a touch panel having high accuracy, high sensitivity, and high durability, and a display device using the same. [0007] A touch screen includes a first electrode plate, the first electrode pad includes a first substrate, a first adhesive layer, and a first transparent conductive layer, and the first transparent conductive layer passes through The first adhesive layer is disposed on a surface of the first substrate; and a second electrode plate includes a second substrate, a second adhesive layer, and a second transparent conductive layer. The second transparent conductive layer is disposed on the second substrate through the second adhesive layer, and the second transparent conductive layer is opposite to and spaced apart from the first transparent conductive layer; wherein the first transparent conductive layer And at least one transparent conductive layer in the second transparent conductive layer 098145169, Form No. A0101, Page 5 of 31, 0982077214-0, 201122630, is a carbon nanotube layer composed of a plurality of carbon nanotubes, And the plurality of carbon nanotubes are arranged in a preferred orientation along the same direction; a transparent insulator is disposed between the first electrode plate and the second electrode plate, and the refractive index of the transparent insulator is greater than the refractive of the vacuum [0008] [0009] 0010] a display device, The display device includes a display and a display disposed on said side facing a user of the touch screen, wherein the touch screen above structure. Compared with the prior art, the touch screen and the display device provided by the invention have the following advantages: First, the carbon nanotube has excellent mechanical properties, so that the nanotube layer has good toughness and mechanical strength, and is resistant to bending, so The use of a carbon nanotube layer as a transparent conductive + electrical layer can correspondingly improve the durability of the touch screen; thereby improving the durability of the display device using the touch screen; second, since the carbon nanotube layer includes a plurality of uniformly distributed nai The carbon nanotubes and the carbon nanotubes have excellent electrical conductivity. Therefore, the carbon nanotube layer is also excellent in electrical conductivity and uniform resistance distribution. Therefore, the carbon nanotube layer is transparently conductive. In order to improve the sensitivity and accuracy of the touch screen, the sensitivity and accuracy of the display device to which the touch screen is applied are improved. [Embodiment] The following will be the case. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A detailed description of the touch screen provided by the system and the display device using the screen is made.

Page 6 of 31 n〇 « 201122630 ❹ [ 0012], a transparent protective film 126 and a shielding layer 146. The first electrode plate 12 and the second electrode plate 14 are disposed at a relatively interval. The transparent insulator 15, the plurality of transparent dot spacers 16 and the insulating frame (4) are disposed between the first-electrode board 12 and the second electrode board 14, and the insulating frame 18 will The first electrode plate 12 is spaced apart from the second electrode plate (four), and the plurality of transparent dot spacers 16 are dispersed in the transparent insulator h.

The first substrate 120 is a planar structure having a first surface 12〇2 and a second surface 12〇4 disposed opposite the first surface 1202. The second surface 1204 is away from the second electrode plate 丨4 ^ The first transparent conductive layer 122 and the two first electrodes 124 are disposed on the first surface 1202 of the first substrate 120|, and the first transparent conductive layer 122 is adhered to the first adhesive layer 128 through the second adhesive layer 128. The first surface 1202 of the first substrate 120.

[0013] The second electrode plate 14 includes a second substrate 14A, a second adhesive layer 148, a second transparent conductive layer 42 and two second electrodes 144. The second substrate 140 has a planar structure and has a first surface 1402 and a second surface 1404 disposed opposite the first surface 1402. The first surface 1402 is away from the surface of the insulating frame 18. The second transparent conductive layer 098145169 Form No. A0101, page 7 / page 31 0982077214-0 201122630 142 and the two second electrodes 144 are disposed on the second surface 14 〇 4 of the second substrate 140, the second transparent The conductive layer 142 is adhered to the second surface 1404 of the second substrate 140 through the second adhesive layer 148. The two second electrodes 144 are respectively disposed on the second transparent conductive layer 142 at two ends in the second direction, that is, the Y-directions shown in FIG. 1 , and are electrically connected to the second transparent conductive layer 142 , and The second transparent conductive layer 142 and the two second electrodes 144 are spaced apart from the first transparent conductive layer 22 and the two first electrodes 24, and the distance between the two is 1-2 micrometers. [0014] wherein the first direction and the second direction are as long as they can intersect. In the present embodiment, the first direction, i.e., the X direction, is perpendicular to the second direction, i.e., the gamma direction, i.e., the two first electrodes 124 are orthogonal to the two second electrodes 144. [0015] The first substrate 120 is a transparent straight film or sheet having a softness. The material of the first substrate 120 is a flexible material such as plastic or tree wax. The second substrate 140 is a transparent substrate. The material of the second substrate 140 may be a hard material such as glass, quartz or diamond, or a flexible material such as plastic or resin. Specifically, the flexible material includes polyester materials such as polycarbonate (PC), polymethyl methacrylate (PMMA), polyethylene terephthalate (PET), and polyether oxime (PES). , cellulose ester, polyethylene (PVC), stupid cyclobutene (BCB) and acrylic resin and other materials. The thickness of the first substrate 120 and the second substrate 140 are respectively 1 mm to 1 cm. In this embodiment, the materials of the first substrate 120 and the second substrate 均为4〇 are both PET, and the thickness is 2 mm. It is to be understood that the material forming the first substrate 120 is not limited to the materials listed above, as long as the first substrate 120 can serve as a support and has a certain flexibility and a good transparency. The material forming the second substrate 并不4〇 is not limited to the above-mentioned list 098145169 Form No. A0101 Page 8 / Total 31 page 0982077214-0 201122630 [0016] 的 [0018] , [0018] The substrate 140 functions as a support and has a certain transparency. The first adhesive layer 128 functions to adhere the first transparent conductive layer 122 to the first surface 1 202 of the first substrate 120. The second adhesive layer 148 functions to adhere the second transparent conductive layer 142 to the second surface 1404 of the second substrate 140. The refractive index of the first adhesive layer 128 and the second adhesive layer 148 is in the range of 1. 30~1. 80. The material of the first adhesive layer 128 and the second adhesive layer 148 is a thermoplastic or UV (Ultraviolet Rays) glue, such as polymethyl methacrylate, polyethylene gas, and the like. In this embodiment, the first adhesive layer 128 and the second adhesive layer 148 have the same material, all of which are polymethyl methacrylate, and the refractive index thereof ranges from 1. 45~1. 53. The first transparent conductive layer 122 and the second transparent conductive layer 142 are both electrically conductive and transparent. The first transparent conductive layer 122 and the second transparent conductive layer 142 are both a carbon nanotube layer. The tube layer is a plurality of carbon nanotubes; 丨; and the plurality of carbon nanotubes are arranged in a preferred orientation along the same direction. Wherein the carbon nanotube layer comprises at least one carbon nanotube film. When the carbon nanotube layer comprises a plurality of carbon nanotube membranes, the carbon nanotube membranes may be disposed in a parallel or gap-free coplanar arrangement or stacked, and the nanocarbons in the plurality of carbon nanotube membranes The tubes are arranged in a preferred orientation in the same direction, that is, the arrangement directions of the carbon nanotubes in the adjacent carbon nanotube membranes are substantially the same. Referring to Figure 3, the carbon nanotube membrane is a self-supporting structure composed of a plurality of carbon nanotubes. The plurality of carbon nanotubes are arranged in a preferred orientation along the same direction. The preferred orientation means that the majority of the carbon nanotubes in the carbon nanotube film extend substantially in the same direction. Moreover, the majority of the Nai 098145169 Form No. A0101 Page 9 of 31 0982077214-0 201122630 The overall extension of the carbon nanotubes is substantially parallel to the surface of the carbon nanotube membrane. Further, most of the carbon nanotubes in the carbon nanotube membrane are connected end to end by van der Waals force. Specifically, each of the plurality of carbon nanotubes extending substantially in the same direction in the carbon nanotube film is connected end to end with a carbon nanotube adjacent in the extending direction by van der Waals force. Of course, there are a small number of randomly arranged carbon nanotubes in the carbon nanotube membrane, which do not significantly affect the overall orientation of most of the carbon nanotubes in the nanotube membrane. The self-supporting carbon nanotube film does not require a large-area carrier support, but can maintain a self-membrane state as long as the supporting force is provided on both sides, that is, the carbon nanotube film is placed (or fixed on) When the two supports are disposed at a certain distance, the carbon nanotube film located between the two supports can be suspended to maintain the self-membrane state. The self-supporting is mainly achieved by continuous carbon nanotubes in the carbon nanotube film, which are arranged end to end by van der Waals force. [0019] Specifically, a plurality of carbon nanotubes extending substantially in the same direction in the carbon nanotube film are not absolutely linear and may be appropriately bent; or are not completely aligned in the extending direction, and may be appropriately deviated. Extend the direction. Therefore, it is not possible to exclude partial contact between the carbon nanotubes juxtaposed in the majority of the carbon nanotube membranes extending substantially in the same direction. [0020] Specifically, the carbon nanotube film includes a plurality of continuous and aligned carbon nanotube segments. The plurality of carbon nanotube segments are connected end to end by Van der Waals force. Each of the carbon nanotube segments includes a plurality of mutually parallel carbon nanotubes, and the plurality of mutually parallel carbon nanotubes are tightly coupled by van der Waals force. The carbon nanotube segments have any length, thickness, uniformity and shape. 098145169 Form No. A0101 Page 10 of 31 0982077214-0 201122630 Shape. The carbon nanotubes in the carbon nanotube film are arranged in a preferred orientation along the same direction. [0021] ❹ The carbon nanotube film can be obtained by directly pulling from a carbon nanotube array. It can be understood that the carbon nanotube structures of different areas and thicknesses can be prepared by laminating a plurality of carbon nanotube films in parallel and without gaps coplanar or/and lamination. When the carbon nanotube structure comprises a plurality of laminated carbon nanotube films, the arrangement of the carbon nanotubes in the adjacent carbon nanotube film forms an angle α, 0° S α €90° . For the structure of the carbon nanotube film, please refer to the publication of the Chinese Patent Publication No. 200833862, published on Aug. 16, 2008. Since the carbon nanotube in the carbon nanotube film has good flexibility, the carbon nanotube film has good flexibility and can be bent and folded into any shape without being easily broken; therefore, the nanometer The carbon tube layer also has better flexibility, so that the touch screen 10 using the carbon nanotube layer as a transparent conductive layer has better durability, thereby making the display device using the touch screen 10 have better durability. [0022] The carbon nanotubes in the carbon nanotube layer include one or more of a single-walled carbon nanotube, a double-walled nanotube, and a multi-walled carbon nanotube. The single-walled carbon nanotube has a diameter of 0. 5 nm ~ 50 nm, the diameter of the double-walled carbon nanotube is 1. 0 nm ~ 50 nm, the diameter of the multi-walled nano tube is 1. 5 nm ~ 50 nm. The carbon nanotubes have a length greater than 50 microns. Preferably, the length of the carbon nanotubes is preferably from 200 microns to 900 microns. It can be understood that one of the first transparent conductive layer 122 and the second transparent conductive layer 142 may be the carbon nanotube layer, and the other transparent conductive layer may be other transparent and conductive. material. 098145169 Form No. 1010101 Page 11/31 Page 0992077214-0 [0023] [0024] The material of the first electrode 124 and the second electrode 144 is metal, carbon nanotube or other conductive material, as long as it is ensured The first electrode 124 and the second electrode 144 can be electrically conductive. In this embodiment, the material of the first electrode 124 and the second electrode 144 is silver. It will be appreciated that the above electrodes for flexible touch screens should also have some toughness and ease of bending. [0025] the transparent insulator 15 is filled between the first transparent conductive layer 122 and the second transparent conductive layer 142, and is in contact with the first transparent conductive layer 122 and the second transparent conductive layer 142, and The first transparent conductive layer 122 is electrically insulated from the second transparent conductive layer 142. The transparent insulator 15 can ensure that the first transparent conductive layer 122 and the second transparent conductive layer 142 are electrically connected when pressed; the transparent insulator 15 can ensure the first transparent after being pressed The conductive layer 122 is electrically insulated from the second transparent conductive layer 142. Referring to FIG. 5, since the second transparent conductive layer 142 is a carbon nanotube layer, the carbon nanotube layer includes a plurality of carbon nanotubes 1422 having a certain gap between the plurality of carbon nanotubes 1422. . When the second transparent conductive layer 142 is adhered to the second substrate 140 through the second adhesive layer 148, since the second adhesive layer 148 has a certain viscosity, the adhesive is filled in the adhesive. In the gap between the plurality of carbon nanotubes 1422, a protrusion 1482 is formed; the transparent insulator 15 is filled in a gap between the plurality of carbon nanotubes 1422 and is in contact with the protrusion 1482. In addition, since the carbon nanotubes have the characteristic of absorbing light, the light beams are emitted from the gaps between the carbon nanotubes, so that the light beams are emitted from the second substrate 140 through the second adhesive layer 148. The transparent insulator 15 is described before it can be ejected. 4 is a view of the touch screen without the transparent insulator 15 of FIG. 2, the light beam 098145169, the form number A0101, the 12th page, the 31st page, the 0902277214-0 201122630, the second transparent conductive layer 142 and the second adhesive layer. The schematic diagram of the light path at the time. Since the second adhesive layer 148 has a determined viscosity which will climb to the surface of the nano tube 1422, the glue filled in the gap between the carbon nanotubes 1422 will form. Protrusion I482. A portion of the composite beam passes through the protrusion 1482 as it passes directly through the second adhesive layer 148. Since the refractive index of the material of the second adhesive layer 148 differs greatly from the refractive index of the vacuum, the protrusion 1482 corresponds to optics. The triangular prism, therefore, causes a dispersion phenomenon when the composite beam passes through the protrusion 1482. That is, since the composite beam includes a plurality of monochromatic lights of different wavelengths, the refractive index of the plurality of monochromatic lights in the second adhesive layer 148 is not so that the plurality of monochromatic lights are from the second adhesive. The refraction of the layer 148 when exiting is also different, such that the portion of the composite beam emerges from the second electrode plate 14 as a plurality of discrete monochromatic lights. Another portion of the composite beam passes through the flat portion between the adjacent protrusions 1482 of the first layer of adhesive layer 148 to form a composite light. The pattern is emitted from the 5th second electrode plate 14. ;; [0027] ❹ . ^ : It can be seen that the light that is incident from the second electrode plate 14 toward the first electrode plate 12 is partially combined light and the other portion is monochromatic light. The structure and material of the first electrode plate 12 are the same as the structure and material of the second electrode plate 14. Therefore, the first adhesive layer of the first electrode plate 12 may also have the first adhesive. The protrusions formed by layer 128. When there is no transparent insulator 15 between the first electrode plate 12 and the second electrode plate 14, the dispersion light may also occur when the composite light passes through the protrusion of the first adhesive layer 128, from the first substrate. 120 emits a plurality of scattered monochrome ^. When the composite light passes through a flat portion between adjacent protrusions of the first adhesive layer 128, it is still emitted from the composite substrate 12Q from the composite light. When the monochromatic light passes through the first adhesive layer 128, which is described in Form No. 098145169, Form No. A0101, Page 13/31, 0982077214-0 201122630, no dispersion occurs, and it is still emitted from the first substrate 120 by monochromatic light. . [0028] When a plurality of scattered monochromatic lights emitted from the first substrate 120 enter the line of sight of the user, the user may see color streaks appear on the touch screen, thereby affecting the resolution of the touch screen. [0029] In order to prevent the dispersion from occurring when the composite beam passes through the protrusions 1482, the material of the transparent insulator 15 is related to the materials of the second adhesive layer 148 and the first adhesive layer 128. Specifically, the material of the transparent insulator 15 is selected according to the refractive index of the second adhesive layer 148 and the first adhesive layer 128, the refractive index of the transparent insulator 15 and the second adhesive layer 148 and the first The closer the refractive index of the adhesive layer 128 is, the better. The refractive index of the second adhesive layer 148 and the first adhesive layer 128 in the embodiment of the present invention is 1. 30~1. Between 80, therefore, the refractive index of the transparent insulator is closer to 1. 30~1. 80 is better. In this embodiment, the refractive index of the second adhesive layer 148 and the first adhesive layer 128 is 1. 45~1. 53. Therefore, the transparent insulator 15 is selected to have a refractive index of 1. Preferably, the terpineol is 48, and the refractive index is closer to the refractive index of the second adhesive layer 148 and the first adhesive layer 128. [0030] The material of the transparent insulator 15 is not limited to terpineol, and its refractive index is greater than the refractive index of the vacuum; this is because when the refractive index of the transparent insulator 15 is greater than the refractive index of the vacuum, the composite beam is from The angle of refraction when the protrusion 1482 is incident on the transparent insulator 15 is smaller than the angle of refraction when the composite beam of FIG. 4 is emitted from the protrusion 1482 toward the vacuum, and therefore, when the refractive index of the transparent insulator 15 is greater than the refractive index of the vacuum At this time, the dispersion effect of the protrusions 1482 on the composite beam is weak relative to the dispersion in FIG. Specifically, the material of the transparent insulator 15 may be polyethylene, poly 098145169 Form No. A0101 Page 14 / Total 31 page 0982077214-0 201122630 Ο [0031] Vinyl chloride, polystyrene, polydecyl methacrylate, pure Water, terpineol, propanol, methanol, ethanol, ethyl hydrazine, carbon tetrachloride, white oil, turpentine, eucalyptus oil, acetone, carbon disulfide, glycerin or trichloromethane. The form of the transparent insulator 15 is not limited and may be liquid or solid. Since the liquid has a certain fluidity, it is convenient to be able to quickly flow from the pressing portion to the non-pressing region when it is pressed, so that the first transparent conductive layer 122 and the second transparent conductive layer 142 are electrically connected; and after pressing, can be quickly Returning from the non-pressing area to the pressing area, the pressing portion can re-energize the first transparent conductive layer 122 and the second transparent conductive layer 142 before pressing; the sensitivity of the touch screen 10 is improved, and therefore, the transparent insulator 15 is preferably in a liquid state. Ο It can be understood that when the transparent insulator 15 is in a solid state, it is a soft transparent insulating film, and the transparent insulating film is deformed under the action of pressure, and the density is reduced, and the first transparent conductive layer 122 and the first transparent conductive layer 122 can be realized. The second transparent conductive layer 142 is electrically connected, and when the transparent insulating phosphine loses the pressure, it can return to the state before the pressure, that is, the first transparent conductive layer 122 and the second transparent conductive layer 142 are re-introduced. Electrical insulation. When the transparent insulator 15 is in a liquid state, since the liquid has a certain fluidity, it is filled by the first transparent conductive layer 122, the second transparent conductive layer 142, and the insulating frame 18 by injection or coating. In space. [0032] It can be understood that when one of the first transparent conductive layer 122 and the second transparent conductive layer 142 is not a carbon nanotube layer but other material layers, for example, when the first transparent layer When the conductive layer 122 is not a carbon nanotube layer, and the second transparent conductive layer 142 is a carbon nanotube layer, the transparent insulator 098145169 Form No. 1010101 Page 15 / Total 31 page 0982077214-0 201122630 15 The material is only based on The refractive index selection of the second adhesive layer 148 does not need to be selected according to the refractive index of the first adhesive layer 128. [0033] Referring to FIG. 5, the light beam from the second substrate 14 is required to pass through the transparent insulator 15 to be directed toward the first electrode plate 2 . Since the refractive index of the transparent insulator 15 is close to or the same as the refractive index of the second adhesive layer 148, that is, the refractive index of the transparent insulator 15 is close to or the same as the refractive index of the protrusion 1482; when the light beam is from The angle of refraction of the protrusion 1482 when it is directed toward the transparent insulator 15 is very small or nearly equal to zero, so that the protrusion 1482 has a very small or substantially no dispersion of the composite beam. That is to say, most of the light that is incident on the first electrode plate 12 is a composite beam, and only a small portion is monochromatic or almost monochromatic. [0034] The light that is incident on the first electrode plate 12 passes through the first adhesive layer 128 and the first substrate 120 in order to emit the touch screen 1〇, which is seen by the user. Since the structure of the first electrode plate 12 is the same as that of the second electrode plate 4, the over-composited composite beam is emitted from the first electrode plate 12 with only a small portion or almost no monochromatic light. The first electrode plate 12 is emitted from the first electrode plate 12; therefore, when the user uses the touch screen, the color stripes seen are relatively weak, or the color stripes are hardly seen, and the resolution of the touch screen 10 is relatively high. Therefore, the transparent insulator 15 has the function of eliminating or weakening the color streaks of the touch screen and improving the resolution of the touch screen. [0036] The plurality of dot spacers 16 are disposed on the second transparent conductive layer 142 of the second electrode plate 14 and the plurality of dot spacers 16 are spaced apart from each other. 098145169 Form No. A0101 Page 16 of 31 0982077214-0 201122630 The insulating frame 18 is disposed between the first surface of the first electrode plate 12' and the second surface 1404 of the second electrode plate 14, Meter, version ^ The transparent insulator 15 is in contact. The plurality of dot spacers 16 and the insulating pivot frame 1 & are made of insulating resin or other insulating material, and can be separated by a child. [0037] The object 16 should be made of a transparent material. The plurality of dot spacers 16 and the insulating frame 18 can electrically insulate the first electrode plate 12 from the second electrode plate u to understand that when the size of the touch screen is small, the plurality of dot isolations are optional structures. As long as the insulating frame 18 can ensure that the first plate 12 and the second electrode plate 14 are electrically insulated. [0038] The shielding layer 146 is disposed on the first surface 14〇2 of the second substrate ho. The shield layer 146 is intended to reduce electromagnetic interference generated by the display and to avoid errors in signals emitted from the touch screen 10. The shield layer ι46 may be formed of a conductive material such as a carbon nanotube or a conductive polymer. In this embodiment, the shielding layer 146 is a carbon nanotube film composed of a carbon nanotube, and the shielding layer 146 acts as an electrical grounding point to function as a mask, so that the touch screen 1 can be interference-free. Working in the environment. It will be appreciated that the shield layer 146 is a • sj* selection structure. The transparent protective film 126 is disposed on the second surface 1204 of the first substrate 12A of the first electrode plate 12. The transparent protective film 126 may be directly bonded to the first substrate 120 by a bonding agent, or may be pressed together with the second substrate 120 by a hot pressing method. The transparent protective film 126 can be a surface-hardened, smooth and scratch-resistant plastic layer or resin layer. The resin layer can be formed from a material such as phenylcyclobutene (BCB), polyester, or acrylic resin. In the embodiment, the material for forming the transparent protective film 126 is polyethylene terephthalate (PET) for protecting the first electrode plate 12 ' 098145169 Form No. A0101 Page 17 of 31 0982077214-0 201122630 Improves durability. The transparent protective film 12 6 can be used to provide additional functions such as glare reduction or reflection reduction after special processing. It can be understood that the touch screen 10 may not be provided with the transparent protective film 126. [0〇39] It can be understood that the two first electrodes 124 may not be disposed on the second electrode plate 12, but may be disposed on the second electrode plate 14 together with the two second electrodes 144. . Specifically, the two first electrodes 124 are spaced apart from each other in the first direction and disposed on the surface of the second transparent conductive layer 142. The two second electrodes 丨4 4 are spaced apart from each other in the second direction. The surface of the second transparent conductive layer 142 is described, and the two first electrodes 124 and the two second electrodes 144 are electrically connected to the second transparent conductive layer 142, respectively, and the first direction intersects with the second direction.

[0041] The touch screen can be spaced apart from the display 430 or integrated on the display 430. When the touch screen 10 is integrated with the display 430, the touch screen 10 can be attached to the display by a transparent adhesive 098145169 Form No. A0101 Page 18 of 31 0982077214-0 201122630 430. When the display 430 is spaced apart from the touch screen 10, a passivation layer 424 may be disposed on the surface of the shield layer 146 of the touch screen 1 away from the second substrate 140. The passivation layer 424 may be made of benzocyclobutene (BCB), A flexible material such as polyester or acrylic resin is formed.
