Abstract
Description
本發明係有關於觸控技術領域,且特別係關於一種觸控面板及其製作方法。 The present invention relates to the technical field of touch control, and in particular, to a touch panel and a manufacturing method thereof.
傳統的觸控技術中,觸控面板係設置於液晶顯示器(liquid crystal display;LCD)、陰極射線管(cathode ray tube;CRT)、場發射顯示器(filed emission display;FED)、等離子(plasma display panel;PDP)或電激發光顯示(electroluminescent display)等圖像顯示元件的顯示面上,讓使用者可藉由碰觸觸控面板並觀看圖案顯示元件來輸入訊息。 In the traditional touch technology, the touch panel is arranged on a liquid crystal display (LCD), a cathode ray tube (CRT), a field emission display (FED), a plasma display panel (plasma display panel) ; PDP) or electroluminescent display (electroluminescent display) and other image display elements on the display surface, allowing users to input information by touching the touch panel and viewing the pattern display element.
觸控面板係多層結構,舉例而言,觸控面板具有蓋板作為第一層以及位於蓋板下方的一層或多層觸控感測結構,兩者係透過黏著層貼合。 The touch panel is a multi-layer structure. For example, the touch panel has a cover plate as the first layer and one or more layers of touch sensing structures under the cover plate, and the two are bonded through an adhesive layer.
本發明之實施方式採用將擴散層直接塗佈於光源、遮蔽層或蓋板上,而免除貼合或黏貼具有擴散功能之擴散 片的步驟。 In the embodiment of the present invention, the diffusion layer is directly coated on the light source, the shielding layer or the cover plate, so as to avoid lamination or sticking of diffusion with diffusion function. slice steps.
於部份實施方式中,一種觸控面板界定有一可視區及一緊鄰可視區的一非可視區,觸控面板包含一蓋板、一光源、一觸控感測結構、一遮蔽層以及一擴散層。光源係位於非可視區內,並被蓋板覆蓋。一觸控感測結構至少係位於可視區內,並被蓋板覆蓋。遮蔽層係位於非可視區內,並被蓋板覆蓋,遮蔽層具有一開口,遮蔽層之開口位於光源之一出光路徑上。擴散層係塗佈於光源、蓋板或遮蔽層,並位於光源之出光路徑上。 In some embodiments, a touch panel defines a visible area and a non-visible area adjacent to the visible area, the touch panel includes a cover plate, a light source, a touch sensing structure, a shielding layer and a diffusion layer. The light source is located in the non-visible area and covered by a cover plate. A touch sensing structure is at least located in the visible area and covered by the cover plate. The shielding layer is located in the non-visible area and is covered by the cover plate. The shielding layer has an opening, and the opening of the shielding layer is located on a light output path of the light source. The diffusion layer is coated on the light source, the cover plate or the shielding layer, and is located on the light output path of the light source.
於部份實施方式中,觸控面板更包含一抗反射層,抗反射層覆蓋蓋板。 In some embodiments, the touch panel further includes an anti-reflection layer, and the anti-reflection layer covers the cover plate.
於部份實施方式中,擴散層係塗佈於光源的面對蓋板的一頂面上。 In some embodiments, the diffusion layer is coated on a top surface of the light source facing the cover plate.
於部份實施方式中,擴散層係塗佈該蓋板之背對光源的一頂面上。 In some embodiments, the diffusion layer is coated on a top surface of the cover plate facing away from the light source.
於部份實施方式中,擴散層係塗佈於遮蔽層之面對光源的一底面上。 In some embodiments, the diffusion layer is coated on a bottom surface of the shielding layer facing the light source.
於部份實施方式中,一種觸控面板的製作方法包含形成具有一開口的一遮蔽層於一蓋板;形成一觸控感測結構於蓋板;設置一光源於遮蔽層之開口下方;以及塗佈一擴散層於光源、蓋板或遮蔽層上。 In some embodiments, a method of fabricating a touch panel includes forming a shielding layer having an opening on a cover plate; forming a touch sensing structure on the cover plate; disposing a light source under the opening of the shielding layer; and A diffusion layer is coated on the light source, the cover plate or the shielding layer.
於部份實施方式中,擴散層係塗佈於蓋板之背對觸控感測結構的一頂面上。 In some embodiments, the diffusion layer is coated on a top surface of the cover plate facing away from the touch sensing structure.
於部份實施方式中,方法更包含設置一抗反射層於該擴散層上方。 In some embodiments, the method further includes disposing an anti-reflection layer over the diffusion layer.
於部份實施方式中,擴散層係塗佈於光源的面對蓋板的一頂面上。 In some embodiments, the diffusion layer is coated on a top surface of the light source facing the cover plate.
於部份實施方式中,擴散層係塗佈於遮蔽層的面對光源的一底面上。 In some embodiments, the diffusion layer is coated on a bottom surface of the shielding layer facing the light source.
於上述實施方式中,由於觸控面板包含擴散層,故可擴散光源射出的光線。舉例而言,當光線通過擴散層時,擴散後的光線可均勻照射到蓋板的按鍵圖案上,免於讓光源射出的光線直接照射到蓋板的按鍵圖案。藉此,擴散層可提高光線的均勻性。此外,由於擴散層係直接塗佈於光源、蓋板或遮蔽層上,故此觸控面板可免去貼合或黏貼擴散片的步驟。如此一來,上述實施方式能在免於貼合或黏貼擴散片的情況下,將擴散層設置於觸控面板中。 In the above-mentioned embodiment, since the touch panel includes the diffusion layer, the light emitted by the light source can be diffused. For example, when the light passes through the diffusion layer, the diffused light can evenly irradiate on the key pattern of the cover, so as to prevent the light emitted from the light source from directly irradiating the key pattern of the cover. Thereby, the diffusion layer can improve the uniformity of light. In addition, since the diffusion layer is directly coated on the light source, the cover plate or the shielding layer, the touch panel can avoid the step of laminating or pasting the diffusion sheet. In this way, the above-mentioned embodiments can dispose the diffusion layer in the touch panel without attaching or sticking the diffusion sheet.
以上所述僅係用以闡述本發明所欲解決的問題、解決問題的技術手段、及其產生的功效等等,本發明之具體細節將在下文的實施方式及相關圖式中詳細介紹。 The above descriptions are only used to describe the problems to be solved by the present invention, the technical means for solving the problems, and their effects, etc. The specific details of the present invention will be described in detail in the following embodiments and related drawings.

As shown in FIG. 1 and FIG. 2 , the
請參閱第3圖,遮蔽層106係位於非可視區14內,並被蓋板108覆蓋。遮蔽層106在非可視區14可位於蓋板108與觸控感測結構104之間,於部份實施方式中,遮蔽層106在
非可視區14可位於蓋板108的下表面,其作用為遮蔽位於非可視區14內的其他電路元件,以保證產品的外觀,其中遮蔽層106的材料為不透光材料,例如有色油墨。於部份實施方式中,遮蔽層106為黑色矩陣(BM;black matrix)。遮蔽層106具有開口O,開口O係位於光源100之出光路徑OP上,開口O係為通過蝕刻的方式形成於遮蔽層106上的鏤空圖案P,如第1圖所示。此鏤空圖案P可為位於非可視區內的觸控功能按鍵圖案、產品的品牌標示或其他裝飾圖案。
Please refer to FIG. 3 , the
於部份實施方式中,觸控感測結構104在非可視區14可位於遮蔽層106的下表面且具有一部份對應至開口O,觸控感測結構104在非可視區14則可設置於蓋板108下方,例如可直接設置在蓋板108的下表面。於部份實施方式中,觸控感測結構104與蓋板108之間在可視區12範圍中亦可設置其他輔助元件層,但本揭露不以此為限。於部份實施方式中,觸控感測結構104可由可視區12延伸至位於非可視區14的圖案P的所在區域,以使觸控面板10位於非可視區14內的圖形按鍵具備觸控功能,但本揭露不以此為限。於部份實施方式中,觸控感測結構104包含第一感測部及一獨立於第一感測部之第二感測部,其中第一感測部位於可視區12,第二感測部位於非可視區14並對應於圖案P,使圖案P處具備觸控感測功能。觸控感測結構104係設置於圖案P所在區域內,由於觸控感測結構104的電極主要由透明導電材質所構成,因此不會遮蔽下方光源的光線。
In some embodiments, the
於部份實施方式中,觸控感測結構104可由透明
導電材料所組成。例如,氧化銦錫(indium tin oxide;ITO)、氧化銦鋅(indium zinc oxide;IZO)、氧化鎘錫(cadmium tin oxide;CTO)、氧化鋁鋅(aluminum zinc oxide;AZO)、氧化銦鋅錫(indium tin zinc oxide;ITZO)、氧化錫(tin oxide)、氧化鋅(zinc oxide)、氧化鎘(cadmium oxide)、氧化鉿(hafnium oxide;HfO)、氧化銦鎵鋅(indium gallium zinc oxide;InGaZnO)、氧化銦鎵鋅鎂(indium gallium zinc magnesium oxide;InGaZnMgO)、氧化銦鎵鎂(indium gallium magnesium oxide;InGaMgO)、氧化銦鎵鋁(indium gallium aluminum oxide;InGaAlO)、奈米碳管(Carbon Nano Tube;CNT)、銀奈米碳管或銅奈米碳管等、或其他透明導電材質,但本揭露不以此為限。
In some embodiments, the
光源100係位於非可視區14內,並被蓋板108覆蓋。於部份實施方式中,光源100具有面向遮蔽層106及蓋板108的出光面S1,且係位於遮蔽層之開口O的下方。於部份實施方式中,光源100係發光二極體或其他適合的發光元件。
The
於本實施方式中,觸控感測結構104下的光源100發出的部份光線會被遮蔽層106阻擋,部份光線可直接通過開口O,如此可凸顯出遮蔽層106的圖案。擴散層102係位於光源100之出光路徑OP上。舉例來說,如第3圖所示,擴散層102係塗佈於光源100之面對蓋板108的出光面S1上,且位於光源100和觸控感測結構104之間,光線依序通過擴散層102、觸控感測結構104、遮蔽層106的開口O以及蓋板108,擴散層102可擴散光源100射出的光線。於部份實施方式中,擴散層102
係包含擴散粒子的油墨或塗料,具有光擴散效果,並係以印刷、噴塗或濺鍍等方式形成於光源100的出光面S1上,但本揭露不以此為限。由於擴散層102係直接塗佈於光源100上,故觸控面板10無須額外的載板來支撐擴散層102,也就是說,觸控面板10免於貼合具有擴散功能的載板的步驟。於部份實施方式中,如第3圖所示,擴散層102係整面地塗佈於光源100的出光面S1上。也就是說,光源100的出光面S1係完全被擴散層102所覆蓋的。但本揭露並不此以為限。舉例來說,在其他實施方式中,如第4圖所示,擴散層102a僅部份地塗佈於光源100的出光面S1上。也就是說,光源100之出光面S1的一部份係被擴散層102a所覆蓋,而另一部份係未被擴散層102a所覆蓋。
In this embodiment, part of the light emitted by the
第5圖繪示根據本揭露另一實施方式之觸控面板的剖面***圖。如第5圖所示,本實施方式與第3圖所示的實施方式之間的主要差異在於:本實施方式所示之擴散層102b係塗佈於遮蔽層106面對光源100的底面S2上,也就是說,擴散層102b係位於觸控感測結構104及遮蔽層106之間,光線依序通過觸控感測結構104、擴散層102b、遮蔽層106的開口O以及蓋板108,擴散層102b可擴散光源100射出的光線,使擴散後的光線通過遮蔽層106的開口O。於部份實施方式中,擴散層102b係包含擴散粒子的油墨或塗料,並係以印刷、噴塗或濺鍍等方式形成於遮蔽層106面對光源100的底面S2上,但本揭露不以此為限。由於擴散層102b係直接塗佈於遮蔽層106上,故觸控面板10無須額外的載板來支撐擴散層102b,也就是說,觸控面板10免於貼合具有擴散功能的載板的步驟。於部
份實施方式中,如第4圖所示,擴散層102b係整面地塗佈於遮蔽層106面對光源的底面S2上。但本揭露並不以此為限。舉例來說,於其他實施方式中,如第6圖所示,擴散層102c係部份地塗佈於遮蔽層106面對光源的底面S2上。
