Description
本發明是有關於一種觸控顯示模組與顯示器，特別是一種消除莫瑞現象的觸控顯示模組與顯示器。 The invention relates to a touch display module and a display, in particular to a touch display module and a display for eliminating the Murray phenomenon.
隨著平面顯示器與觸控輸入裝置的技術快速發展，為了在有限的體積下，讓使用者有較大的可視畫面以及提供更方便的操作模式，某些電子產品將觸控面板與顯示面板結合，而構成觸控顯示面板。 With the rapid development of the technology of flat panel displays and touch input devices, in order to allow users to have larger visual images and provide more convenient operation modes under limited volume, some electronic products combine touch panels with display panels. And constitute a touch display panel.
觸控面板的操作原理為，當一導體物件(例如手指)接觸到觸控面板的觸控感測陣列時，觸控感測陣列的電氣特性(例如電阻值或電容值)會隨著改變，並導致觸控感測陣列的偏壓改變。此電氣特性上的改變會轉換為控制訊號傳送至外部之控制電路板上，並經由處理器進行資料處理並運算得出結果。接著，再藉由外部控制電路板輸出一顯示訊號至顯示面板中，並經由顯示面板將影像顯示在使用者眼前。 The operating principle of the touch panel is that when a conductor object (such as a finger) contacts the touch sensing array of the touch panel, the electrical characteristics (such as resistance value or capacitance value) of the touch sensing array may change. And causing the bias of the touch sensing array to change. This change in electrical characteristics is converted to a control signal that is transmitted to the external control board and processed by the processor for data processing. Then, a display signal is outputted to the display panel by the external control circuit board, and the image is displayed in front of the user through the display panel.
由於觸控面板為疊置於顯示面板之上，因此，當採用金屬網格的設計時，金屬網格的細線會因線條重疊而產生影像模糊的莫瑞效應(moiré phenomenon)。雖然當金屬網格 的線寬尺寸越小時，莫瑞效應越不明顯。然而，金屬網格的線寬尺寸受限於其製造方式，線寬尺寸越小的金屬網格需要更高的成本，且其線寬尺寸無法無限制的縮小。因此，如何能有效解决上述問題，實屬當前重要研發課題之一，亦成為當前相關領域亟需改進的目標。 Since the touch panel is superimposed on the display panel, when the design of the metal mesh is adopted, the thin line of the metal mesh may cause a moiré phenomenon of image blur due to overlapping lines. Although as a metal grid The smaller the line width size, the less obvious the Murray effect. However, the wire width of the metal mesh is limited by the way in which it is manufactured, and the metal mesh having a smaller line width requires a higher cost, and the line width size cannot be reduced indefinitely. Therefore, how to effectively solve the above problems is one of the current important research and development topics, and it has become an urgent target for improvement in related fields.

以下將以圖式及詳細說明清楚說明本發明之精神，任何所屬技術領域中具有通常知識者在了解本發明之較佳實施例後，當可由本發明所教示之技術，加以改變及修飾，其 並不脫離本發明之精神與範圍。 The spirit and scope of the present invention will be apparent from the following description of the preferred embodiments of the invention. The spirit and scope of the invention are not departed.
當觸控面板採用金屬網格設計時，金屬網格的細線會因線條重疊而產生影像模糊的莫瑞效應(moiré phenomenon)，其中金屬網格的線寬與莫瑞效應具有相關性。當金屬網格的線寬尺寸越大時，則莫瑞效應越明顯。反之，當金屬網格的線寬尺寸越小時，則莫瑞效應相對不明顯。然而，金屬網格的線寬尺寸受限於其製造方式，其線寬無法無限制的縮小，且小尺寸的線寬又會提高成本。因此，當金屬網格的觸控面板應用在高解析度面板上時，莫瑞效應的產生將會大幅破壞影像品質。 When the touch panel is designed with a metal mesh, the thin lines of the metal mesh may cause a moiré phenomenon of image blur due to overlapping lines, wherein the line width of the metal mesh is correlated with the Murray effect. When the line width of the metal mesh is larger, the Murray effect is more pronounced. Conversely, when the line width of the metal mesh is smaller, the Murray effect is relatively insignificant. However, the wire width of the metal mesh is limited by the way it is manufactured, the line width cannot be reduced without limitation, and the small line width increases the cost. Therefore, when the touch panel of the metal grid is applied to the high-resolution panel, the generation of the Murray effect will greatly degrade the image quality.
鑒於觸控面板因金屬網格產生影像模糊的莫瑞效應，本發明之觸控顯示模組於第二基板表面設置微結構，且微結構的延伸方向與第二基板的側邊夾一非垂直角，使得微結構霧化金屬網格的細線。因此，本發明之觸控顯示模組因莫瑞效應導致的影像模糊現象將大幅被改善。此外，微結構同時也使得本發明之觸控顯示模組的出光具有較高的準直性，使得其出光亮度提昇，並藉此改善金屬材料因透光不足而產生的低亮度。 The touch display module of the present invention is provided with a microstructure on the surface of the second substrate, and the extending direction of the microstructure is non-perpendicular to the side of the second substrate. The corners cause the microstructure to atomize the fine lines of the metal grid. Therefore, the image blurring phenomenon caused by the Murray effect of the touch display module of the present invention is greatly improved. In addition, the microstructure also makes the light output of the touch display module of the present invention have high collimation, so that the brightness of the light is improved, and thereby the low brightness of the metal material due to insufficient light transmission is improved.
請同時參照第1圖以及第2圖。第1圖為依照本發明之觸控顯示模組一實施例的側視示意圖，第2圖為依照本發明之第二基板一實施例的立體示意圖。觸控顯示模組100包含第一基板110、第二基板140、液晶層120、金屬網格觸控層130以及微結構142。第二基板140相對於第一基板110設置。液晶層120設置於第一基板110與第二基板140之間。金屬網格觸控 層130設置於第二基板140與液晶層120之間。微結構142設置於第二基板140上，且對應位於金屬網格觸控層130之另側。微結構142互相平行且凸出於第二基板140之表面，其中微結構142的延伸方向與第二基板140表面的側邊之夾角可為銳角或鈍角。 Please refer to both Figure 1 and Figure 2. 1 is a side elevational view of an embodiment of a touch display module in accordance with the present invention, and FIG. 2 is a perspective view of an embodiment of a second substrate in accordance with the present invention. The touch display module 100 includes a first substrate 110 , a second substrate 140 , a liquid crystal layer 120 , a metal grid touch layer 130 , and a microstructure 142 . The second substrate 140 is disposed relative to the first substrate 110. The liquid crystal layer 120 is disposed between the first substrate 110 and the second substrate 140. Metal grid touch The layer 130 is disposed between the second substrate 140 and the liquid crystal layer 120. The microstructures 142 are disposed on the second substrate 140 and corresponding to the other side of the metal grid touch layer 130. The microstructures 142 are parallel to each other and protrude from the surface of the second substrate 140. The angle between the extending direction of the microstructures 142 and the sides of the surface of the second substrate 140 may be an acute angle or an obtuse angle.
本實施例中，金屬網格觸控層130與液晶層120的共同設置使得觸控功能以及顯示功能整合於一體，根據本發明一實施例，觸控顯示模組100更包含薄膜電晶體(thin-film transistor；TFT，未繪示)，並設置於第一基板110與液晶層120之間。也就是說，金屬網格觸控層130除了提供觸控功能之外，其更與薄膜電晶體共同產生控制液晶層120的電場，以提供顯示功能。 In this embodiment, the common arrangement of the metal grid touch layer 130 and the liquid crystal layer 120 integrates the touch function and the display function. According to an embodiment of the invention, the touch display module 100 further includes a thin film transistor (thin a TFT (not shown) is disposed between the first substrate 110 and the liquid crystal layer 120. That is to say, in addition to providing a touch function, the metal mesh touch layer 130 further generates an electric field for controlling the liquid crystal layer 120 together with the thin film transistor to provide a display function.
觸控顯示模組100於使用時，第二基板140的微結構142朝向使用者。此外，由於微結構142的延伸方向與第二基板140表面的側邊不平行也不為垂直相交，如第2圖所示，因此，微結構142對金屬網格觸控層130具有霧化效果，而使得金屬網格觸控層130產生的莫瑞效應有效被改善。 When the touch display module 100 is in use, the microstructure 142 of the second substrate 140 faces the user. In addition, since the extending direction of the microstructure 142 is not parallel to the side of the surface of the second substrate 140 and does not vertically intersect, as shown in FIG. 2, the microstructure 142 has an atomizing effect on the metal grid touch layer 130. The Murray effect generated by the metal grid touch layer 130 is effectively improved.
此外，由於金屬網格觸控層130相較於透明導電材料具有低阻抗的特性，使得觸控顯示模組100於觸控操作時具有更快的反應速度。也因此，觸控顯示模組100能更準確地感測使用者操作時的觸控位置。 In addition, since the metal grid touch layer 130 has a low impedance characteristic compared to the transparent conductive material, the touch display module 100 has a faster reaction speed when the touch operation is performed. Therefore, the touch display module 100 can more accurately sense the touch position when the user operates.
根據本發明一或多個實施例，液晶層120為藍相液晶(blue phase liquid crystal)層或光學補償彎曲液晶(optically compensated bend liquid crystal)層。 According to one or more embodiments of the present invention, the liquid crystal layer 120 is a blue phase liquid crystal layer or an optically compensated bend liquid crystal layer.
當液晶層120採用藍相液晶層時，液晶層120具有亞毫秒的響應時間，使得觸控顯示模組100具有極快速的反應時間，並可降低動態偽像。此外，採用藍相液晶層的液晶層120不需要設置定向層，因此可以簡化製程。 When the liquid crystal layer 120 adopts a blue phase liquid crystal layer, the liquid crystal layer 120 has a response time of sub-millisecond, so that the touch display module 100 has extremely fast reaction time and can reduce dynamic artifacts. Further, the liquid crystal layer 120 using the blue phase liquid crystal layer does not need to be provided with an alignment layer, so that the process can be simplified.
相同地，當液晶層120採用光學補償彎曲液晶層時，觸控顯示模組100同樣具有極快速的反應時間。因此，本發明之觸控顯示模組100除了將觸控以及顯示整合於一體外，其也呈現高品質的動畫品質。 Similarly, when the liquid crystal layer 120 is optically compensated for bending the liquid crystal layer, the touch display module 100 also has an extremely fast reaction time. Therefore, the touch display module 100 of the present invention exhibits high-quality animation quality in addition to integrating touch and display into one body.
除此之外，根據本發明一或多個實施例，凸出於第二基板140表面之微結構142的高度H為80微米(μm)至150微米(μm)之間，因此，第二基板140表面為具有起伏的表面。更進一步而言，微結構142可視為稜鏡陣列，當光線自液晶層120射向微結構142時，微結構142提升觸控顯示模組100平行於第二基板140法向量的出光量。因此，作為稜鏡陣列的微結構142同時也改善金屬網格觸控層130透光較低(相較於透明導電材料)而導致亮度較低的問題。 In addition, according to one or more embodiments of the present invention, the height H of the microstructure 142 protruding from the surface of the second substrate 140 is between 80 micrometers (μm) and 150 micrometers (μm), and thus, the second substrate The surface of 140 is an undulating surface. Further, the microstructure 142 can be regarded as an array of ridges. When the light is emitted from the liquid crystal layer 120 to the microstructure 142, the microstructure 142 increases the amount of light emitted by the touch display module 100 parallel to the normal vector of the second substrate 140. Therefore, the microstructure 142 as the germanium array also improves the low light transmission of the metal mesh touch layer 130 (compared to the transparent conductive material).
根據本發明一或多個實施例，觸控顯示模組100更包含介質層160。介質層160設置於微結構142上，其中介質層160相對第二基板140之表面為平坦表面。介質層160材料為具有透光性的高分子材料，例如樹脂或聚酸甲酯(Polymethylmethacrylate；PMMA)。介質層160可作為保護微結構142的保護層，使得微結構142的結構不會因為使用者的觸控操作而遭受破壞。除此之外，平坦的介質層160表面也利於觸控顯示模組100再與其他元件連接。 According to one or more embodiments of the present invention, the touch display module 100 further includes a dielectric layer 160. The dielectric layer 160 is disposed on the microstructure 142, wherein the surface of the dielectric layer 160 relative to the second substrate 140 is a flat surface. The material of the dielectric layer 160 is a light transmissive polymer material such as a resin or a polymethylmethacrylate (PMMA). The dielectric layer 160 can serve as a protective layer for the protective microstructure 142 such that the structure of the microstructure 142 is not damaged by the touch operation of the user. In addition, the surface of the flat dielectric layer 160 also facilitates the connection of the touch display module 100 to other components.
綜上所述，本發明之觸控顯示模組100佈有微結構142於第二基板140上，使得當使用者操作使用時，微結構142對金屬網格觸控層130具有霧化效果，降低莫瑞效應。同時，微結構142可作為透鏡陣列，以提供使用者更佳的亮度，並藉此改善金屬網格觸控層130中金屬材質造成的低亮度問題。此外，根據本發明一實施例，觸控顯示模組100於第一基板110以及第二基板140間無設置彩色濾光層，因此觸控顯示模組100可與三色發光二極體(RGB light-emitting diode)結合作應用。 In summary, the touch display module 100 of the present invention is provided with the microstructure 142 on the second substrate 140, so that the microstructure 142 has an atomizing effect on the metal grid touch layer 130 when the user operates. Reduce the Murray effect. At the same time, the microstructure 142 can serve as a lens array to provide better brightness for the user and thereby improve the low brightness problem caused by the metal material in the metal grid touch layer 130. In addition, according to an embodiment of the invention, the touch display module 100 is not provided with a color filter layer between the first substrate 110 and the second substrate 140, so the touch display module 100 can be combined with a three-color LED (RGB). Light-emitting diode).
本發明之觸控顯示模組100透過第二基板140上的微結構142霧化金屬網格觸控層130以降低莫瑞效應的方式已詳述於以上實施例，在接下來的的實施例中，將對應用第二基板140上的微結構142於本發明之顯示器作霧化進行說明，與之前實施例相同之處將不再贅述。 The manner in which the touch display module 100 of the present invention atomizes the metal mesh touch layer 130 through the microstructure 142 on the second substrate 140 to reduce the Murray effect has been described in detail in the above embodiments, in the following embodiments. The application of the microstructure 142 on the second substrate 140 to the display of the present invention will be described. The same points as in the previous embodiment will not be described again.
請同時參照第2圖以及第3圖，第3圖為依照本發明之顯示器一實施例的側視示意圖。顯示器102包含第一基板110、第二基板140、液晶層120、觸控層131、微結構142、第一偏光片150以及光源154。第二基板140相對於第一基板110設置。液晶層120設置於第一基板110與第二基板140之間。觸控層131設置於第二基板140與液晶層120之間。微結構142設置於第二基板140上，且對應位於觸控層131之另側。顯示器102的微結構142設置方式同於觸控顯示模組(請見第1圖)，微結構142互相平行且凸出於第二基板140之表面，微結構142的延伸方向與第二基板140表面的側邊之夾角可為銳角 或鈍角，如第2圖所示。第一偏光片150設置於第一基板110相對於液晶層120之一側。光源154設置於第一偏光片150相對第一基板110之一側，且光源154為三色發光二極體。此外，第一基板110及第二基板140之間無設置彩色濾光層。 Please refer to FIG. 2 and FIG. 3 at the same time. FIG. 3 is a side view showing an embodiment of a display according to the present invention. The display 102 includes a first substrate 110, a second substrate 140, a liquid crystal layer 120, a touch layer 131, a microstructure 142, a first polarizer 150, and a light source 154. The second substrate 140 is disposed relative to the first substrate 110. The liquid crystal layer 120 is disposed between the first substrate 110 and the second substrate 140. The touch layer 131 is disposed between the second substrate 140 and the liquid crystal layer 120. The microstructure 142 is disposed on the second substrate 140 and corresponding to the other side of the touch layer 131. The microstructures 142 of the display 102 are disposed in the same manner as the touch display module (see FIG. 1 ). The microstructures 142 are parallel to each other and protrude from the surface of the second substrate 140 . The extending direction of the microstructures 142 and the second substrate 140 . The angle between the sides of the surface can be an acute angle Or obtuse angle, as shown in Figure 2. The first polarizer 150 is disposed on one side of the first substrate 110 with respect to the liquid crystal layer 120. The light source 154 is disposed on one side of the first polarizer 150 opposite to the first substrate 110, and the light source 154 is a three-color light emitting diode. Further, no color filter layer is provided between the first substrate 110 and the second substrate 140.
由於顯示器102採用的光源154為三色發光二極體，因此即使第一基板110以及第二基板140間沒有設置彩色濾光層，顯示器102仍可提供彩色輸出。除此之外，由於觸控層131與液晶層120皆位於第一基板110以及第二基板140之間，且第二基板140上設置有微結構142，因此，觸控層131所具有作為感測觸控的電極圖案會被霧化。也就是說，透過微結構142霧化觸控層131的電極圖案，觸控層131所產生的莫瑞效應將受到改善。 Since the light source 154 used in the display 102 is a three-color light emitting diode, the display 102 can provide a color output even if no color filter layer is disposed between the first substrate 110 and the second substrate 140. In addition, since the touch layer 131 and the liquid crystal layer 120 are located between the first substrate 110 and the second substrate 140, and the microstructure 142 is disposed on the second substrate 140, the touch layer 131 has a sense of The electrode pattern of the touch sensor is atomized. That is to say, by atomizing the electrode pattern of the touch layer 131 through the microstructure 142, the Murray effect generated by the touch layer 131 will be improved.
根據本發明一或多個實施例，觸控層131為金屬網格觸控層。由於金屬網格觸控層具有低阻抗的特性，其使得顯示器102具有更快的觸控反應速度，也因此顯示器102能更準確感測使用者的觸控位置。此外，金屬網格觸控層雖然因線寬限制而存在有莫瑞效應的問題，透過微結構142霧化其具有的金屬細線，莫瑞效應的問題能有效被改善。 According to one or more embodiments of the present invention, the touch layer 131 is a metal mesh touch layer. Since the metal grid touch layer has low impedance characteristics, the display 102 has a faster touch response speed, and thus the display 102 can more accurately sense the user's touch position. In addition, although the metal grid touch layer has a problem of the Murray effect due to the line width limitation, the problem of the Murray effect can be effectively improved by atomizing the fine metal wires of the microstructure 142.
同樣地，本實施例中，觸控層131與液晶層120的共同設置使得觸控功能以及顯示功能整合於一體，根據本發明一實施例，顯示器102更包含薄膜電晶體(未繪示)，並設置於第一基板110與液晶層120之間。因此，觸控層131除了提供觸控功能之外，其更與與薄膜電晶體共同產生控制液晶層120的電場，以提供顯示功能。 Similarly, in the embodiment, the touch layer 131 and the liquid crystal layer 120 are integrated to integrate the touch function and the display function. According to an embodiment of the invention, the display 102 further includes a thin film transistor (not shown). And disposed between the first substrate 110 and the liquid crystal layer 120. Therefore, in addition to providing a touch function, the touch layer 131 generates an electric field for controlling the liquid crystal layer 120 together with the thin film transistor to provide a display function.
相同地，根據本發明一或多個實施例，液晶層120為藍相液晶層或光學補償彎曲液晶層，其特性已詳述於前，在此不再贅述。並且，根據本發明一或多個實施例，凸出於第二基板140表面之微結構142的高度H為80微米(μm)至150微米(μm)之間。相同地，第二基板140表面為具有起伏的表面，且微結構142可視為稜鏡陣列，以提升顯示器102平行於第二基板140法向量的出光量。 Similarly, according to one or more embodiments of the present invention, the liquid crystal layer 120 is a blue phase liquid crystal layer or an optically compensated curved liquid crystal layer, and its characteristics have been described in detail above, and will not be described herein. Moreover, according to one or more embodiments of the present invention, the height H of the microstructures 142 protruding from the surface of the second substrate 140 is between 80 micrometers (μm) and 150 micrometers (μm). Similarly, the surface of the second substrate 140 is a surface having an undulation, and the microstructure 142 can be regarded as an array of turns to enhance the amount of light emitted by the display 102 parallel to the normal vector of the second substrate 140.
此外，根據本發明一或多個實施例，顯示器102更包含介質層160以及第二偏光片152。介質層160設置於微結構142上。介質層160相對第二基板140之表面為平坦表面。第二偏光片152設置於介質層160之平坦表面上。 Moreover, in accordance with one or more embodiments of the present invention, display 102 further includes a dielectric layer 160 and a second polarizer 152. The dielectric layer 160 is disposed on the microstructures 142. The surface of the dielectric layer 160 opposite to the second substrate 140 is a flat surface. The second polarizer 152 is disposed on a flat surface of the dielectric layer 160.
介質層160材料為具有透光性的高分子材料，例如樹脂或聚酸甲酯。介質層160可作為保護微結構142的保護層，使得微結構142不會因為使用者的觸控操作而遭受破壞。 The material of the dielectric layer 160 is a light transmissive polymer material such as a resin or a polymethyl ester. The dielectric layer 160 can serve as a protective layer for the protective microstructures 142 such that the microstructures 142 are not damaged by the touch operation of the user.
第一偏光片150以及第二偏光片152為對應液晶層120，於此共同配置下，顯示器102的顯示輸出為透過控制液晶層120完成。 The first polarizer 150 and the second polarizer 152 are corresponding to the liquid crystal layer 120. In this common configuration, the display output of the display 102 is completed by controlling the liquid crystal layer 120.
綜上所述，本發明之顯示器102佈有微結構142於第二基板140上，使得當使用者操作使用時，微結構142對觸控層131具有霧化效果，降低莫瑞效應。同時，微結構142可作為透鏡陣列，並在搭配光源154後，提供使用者更佳的亮度。此外，本發明之顯示器102中並無彩色濾光層的設置，因此在結構設置上有更多的彈性。 In summary, the display 102 of the present invention is provided with a microstructure 142 on the second substrate 140, so that when the user operates, the microstructure 142 has an atomizing effect on the touch layer 131, reducing the Murray effect. At the same time, the microstructures 142 can serve as a lens array and provide better brightness to the user after the light source 154 is matched. In addition, the display 102 of the present invention does not have the arrangement of color filter layers, and thus has more flexibility in structural arrangement.
本發明之觸控顯示模組/顯示器如何透過微結構 降低莫瑞效應已詳述於以上實施例，在接下來的的實施例中，將對觸控顯示模組/顯示器的微結構作更進一步的說明，與之前實施例相同之處將不再贅述。除此之外，由於觸控顯示模組以及顯示器皆具有微結構，因此，以下圖式以及敘述為將觸控顯示模組以及顯示器合併作說明，合先敘明。 How does the touch display module/display of the present invention pass through the microstructure The reduction of the Murray effect has been described in detail in the above embodiments. In the following embodiments, the microstructure of the touch display module/display will be further described, and the same as the previous embodiment will not be described again. . In addition, since the touch display module and the display have a micro structure, the following figures and descriptions are combined to illustrate the touch display module and the display.
請參照第4圖，第4圖為依照本發明之觸控顯示模組/顯示器一實施例的上視示意圖。觸控顯示模組100/顯示器102的第二基板140上佈滿有微結構142，其中微結構142互相平行且為週期性排列。更具體而言，平行排列的微結構142為等間距排列，且間距P為40微米(μm)至60微米(μm)之間。 Please refer to FIG. 4, which is a top view of an embodiment of a touch display module/display according to the present invention. The second substrate 140 of the touch display module 100 / display 102 is covered with microstructures 142 , wherein the microstructures 142 are parallel to each other and are periodically arranged. More specifically, the parallel arrays of microstructures 142 are equally spaced and have a pitch P between 40 micrometers (μm) and 60 micrometers (μm).
根據本發明一或多個實施例，微結構142具有延伸方向D，其中微結構142的延伸方向D與第二基板140表面的側邊所夾之銳角介於20度至45度之間。具體而言，微結構142的延伸方向D與第二基板的側邊具有夾角θ1以及夾角θ2，其中夾角θ1與夾角θ2的和為90度。 According to one or more embodiments of the present invention, the microstructure 142 has an extending direction D, wherein an acute angle between the extending direction D of the microstructure 142 and the side of the surface of the second substrate 140 is between 20 degrees and 45 degrees. Specifically, the extending direction D of the microstructure 142 has an angle θ 1 and an included angle θ 2 with respect to the side of the second substrate, wherein the sum of the included angle θ 1 and the included angle θ 2 is 90 degrees.
在微結構142的設置中，可以以夾角θ1為主，即夾角θ1為介於20度至45度之間，而夾角θ2為對應夾角θ1。例如，夾角θ1為30度，而夾角θ2為60度。 In the arrangement of the microstructures 142, the angle θ 1 may be dominant, that is, the angle θ 1 is between 20 degrees and 45 degrees, and the angle θ 2 is the corresponding angle θ 1 . For example, the included angle θ 1 is 30 degrees, and the included angle θ2 is 60 degrees.
反之，也可以以夾角θ2為主，即夾角θ2為介於20度至45度之間，而夾角θ1為對應夾角θ2。例如，夾角θ2為40度，而夾角θ1為50度。 Conversely, the angle θ 2 may be dominant, that is, the angle θ 2 is between 20 degrees and 45 degrees, and the angle θ 1 is the corresponding angle θ 2 . For example, the included angle θ 2 is 40 degrees, and the included angle θ 1 is 50 degrees.
除此之外，金屬網格觸控層(請見第1圖)具有金屬網格132，其中金屬網格132包含由金屬細線所框出的外圍，以及位於金屬框線內的格子狀金屬細線，由於實務上金屬網格 132的線寬有一定限制，透過上述微結構142配置，作為稜鏡陣列的微結構142均勻霧化金屬網格132的金屬細線，使得觸控顯示模組100的莫瑞效應有效被改善。 In addition, the metal mesh touch layer (see FIG. 1) has a metal mesh 132, wherein the metal mesh 132 includes a periphery surrounded by thin metal wires, and a lattice-shaped metal thin wire located inside the metal frame wires. Due to the practice of metal grid The line width of 132 is limited. The microstructure 142 of the array is uniformly atomized by the microstructure 142 of the array. The metal effect of the metal grid 132 is uniformly atomized, so that the Murray effect of the touch display module 100 is effectively improved.
更進一步而言，由於金屬網格132的金屬框線和框線內的格子狀金屬細線為對稱形的網狀圖案，當微結構142的延伸方向D與金屬框線和框線內的格子狀金屬細線夾非垂直角(例如銳角或鈍角)時，微結構142對金屬網格132具有霧化效果。 Furthermore, since the metal frame lines of the metal mesh 132 and the lattice-shaped metal thin wires in the frame lines are symmetrical mesh patterns, when the microstructure 142 extends in the direction D and the metal frame lines and the grid lines in the frame lines The microstructure 142 has an atomizing effect on the metal mesh 132 when the metal thin wire clip is not at a perpendicular angle (for example, an acute angle or an obtuse angle).
同樣地，當觸控層(請見第3圖)為金屬網格觸控層時，其所具有金屬網格132的也可同上述微結構142的設置方式而被霧化。 Similarly, when the touch layer (see FIG. 3) is a metal mesh touch layer, the metal mesh 132 having the metal mesh 132 can also be atomized in the same manner as the above-described microstructure 142.
然而，應了解到，第4圖所繪之金屬網格132形狀僅為例示，而非用以限制本發明，本發明所屬技術領域中具有通常知識者，可依實際需要，彈性選擇金屬網格132的圖案形狀。 However, it should be understood that the shape of the metal mesh 132 depicted in FIG. 4 is merely an example, and is not intended to limit the present invention. Those skilled in the art to which the present invention pertains may flexibly select a metal mesh according to actual needs. 132 pattern shape.
請同時參照第5圖，第5圖為本發明觸控顯示模組/顯示器之微結構於多個實施例的側視示意圖。於第1圖的觸控顯示模組以及第3圖的顯示器中，微結構142之截面為三角形。根據本發明一或多個實施例，微結構142之截面為三角形、半圓形、橢圓形或梯形，如第5圖所示，其中第5圖最右側之截面為以梯形作基底，而其上底為弧形。具體而言，微結構142形狀具有改變光線路徑的效果，使得金屬網格觸控層(請見第1圖)中的金屬細線被霧化，以降低莫瑞效應。同樣地，觸控層(請見第3圖)中的電極圖案也會因被霧化而降低莫瑞效應。 Please refer to FIG. 5 at the same time. FIG. 5 is a side view of the microstructure of the touch display module/display of the present invention in various embodiments. In the touch display module of FIG. 1 and the display of FIG. 3, the microstructure 142 has a triangular cross section. According to one or more embodiments of the present invention, the microstructure 142 has a triangular, semi-circular, elliptical or trapezoidal cross section, as shown in FIG. 5, wherein the rightmost cross section of the fifth figure is a trapezoidal substrate, and The upper base is curved. In particular, the microstructure 142 shape has the effect of changing the ray path such that the metal lines in the metal grid touch layer (see Figure 1) are atomized to reduce the Murray effect. Similarly, the electrode pattern in the touch layer (see Figure 3) will also reduce the Murray effect due to atomization.
然而，應了解到，以上所舉之微結構142截面形狀非用以限制本發明，本發明所屬技術領域中具有通常知識者，可依實際需要，彈性選擇改變光線路徑以達到霧化金屬網格觸控層/觸控層效果的微結構142截面形狀。 However, it should be understood that the above-mentioned cross-sectional shape of the microstructure 142 is not intended to limit the present invention. Those skilled in the art to which the present invention pertains may flexibly select a light path to achieve an atomized metal mesh according to actual needs. The microstructure of the touch layer/touch layer effect is 142.
綜合以上實施例，本發明之觸控顯示模組以及顯示器具有微結構，且微結構可以霧化觸控層的電極圖案，使得莫瑞效應受到改善。特別是對於使用金屬網格的觸控層，由於小尺寸線寬會造成成本提升，搭配微結構霧化後，金屬網格的線寬要求可以具有彈性，使得金屬網格能更佳突顯其低成本的優勢。此外，微結構可以作為透鏡陣列，以提升觸控顯示模組以及顯示器的出光量，使得使用者能有更佳的影像品質，並也同時改善採用金屬材質作為觸控層產生的低亮度問題。 In combination with the above embodiments, the touch display module and the display of the present invention have a microstructure, and the microstructure can atomize the electrode pattern of the touch layer, so that the Murray effect is improved. Especially for the touch layer using the metal mesh, the cost is increased due to the small line width.
