Description
本發明是有關於一種薄膜及其製造方法與應用其之顯示裝置，且特別是有關於一種抗污薄膜及其製造方法與應用其之電子裝置。The present invention relates to a film, a method for fabricating the same, and a display device therefor, and more particularly to an antifouling film, a method for fabricating the same, and an electronic device using the same.
隨著技術的發展，各式產品不斷推陳出新。面對眾多的產品，消費者不僅重視產品的功能，也相當重視產品的外觀的維持。水滴或油滴所形成的髒污，很快就會破壞產品新穎的外觀。所以保護袋或保護膜等配件也成為熱銷的項目之一。With the development of technology, various products are constantly being updated. Faced with numerous products, consumers not only pay attention to the function of the product, but also pay attention to the maintenance of the appearance of the product. The dirt formed by water droplets or oil droplets will quickly destroy the novel appearance of the product. Therefore, accessories such as protective bags or protective films have also become one of the hot-selling items.
然而，保護袋只能消極的把產品與外界作隔離。在使用者操作該產品的過程中，難免需要從保護袋中拿出該產品，而使該產品仍然有受到髒污的可能性。However, the protective bag can only passively isolate the product from the outside world. In the process of the user operating the product, it is inevitable that the product needs to be taken out of the protective bag, so that the product is still contaminated.
此外，保護膜本身也容易受到髒污，使用者只能在保護膜髒污後消極的更換新的保護膜，而無法真正降低髒污的情況。In addition, the protective film itself is also susceptible to dirt, and the user can only passively replace the new protective film after the protective film is dirty, and cannot truly reduce the contamination.
尤其是顯示產品或觸控產品，其顯示面或觸控面髒污時，將立即嚴重影響顯示品質或觸控效果。不論是保護膜或保護袋，對於上述產品來說，均不是方便的抗污方式。In particular, when the display surface or the touch surface is dirty, the display product or the touch control product will immediately affect the display quality or the touch effect. Whether it is a protective film or a protective bag, it is not a convenient anti-fouling method for the above products.

請參照第2圖，其繪示第一實施例之抗污薄膜100之示意圖。抗污薄膜100包括一基材190(繪示於第3圖)、一第一抗污材料110及一第二抗污材料120。基材190例如是一玻璃基板或一塑膠基板。基材190可以是上述顯示單元900之保護板或上述觸控單元之保護板。第一抗污材料110及第二抗污材料120可以直接形成於上述顯示單元900之保護板或上述觸控單元之保護板上，或者可以先形成於一暫時板，再轉印至上述顯示單元900之保護板或上述觸控單元之保護板上。基材190具有數個第一區域191及數個第二區域192。第一抗污材料110設置於此些第一區域191。第二抗污材料120設置於此些第二區域192。第一抗污材料110與第二抗污材料120並沒有混合，而是分別設置於不同的區域。本實施例之此些第一區域191及第二區域192交錯排列。此些第一區域191及此些第二區域192係為長條狀交錯排列，且此些第一區域191之寬度W191實質上等於此些第二區域192之寬度W192。Referring to FIG. 2, a schematic view of the anti-fouling film 100 of the first embodiment is shown. The anti-fouling film 100 includes a substrate 190 (shown in FIG. 3), a first anti-fouling material 110, and a second anti-fouling material 120. The substrate 190 is, for example, a glass substrate or a plastic substrate. The substrate 190 may be a protection board of the display unit 900 or a protection board of the touch unit. The first anti-fouling material 110 and the second anti-fouling material 120 may be directly formed on the protection board of the display unit 900 or the protection panel of the touch unit, or may be formed on a temporary board and then transferred to the display unit. The protection board of 900 or the protection board of the above touch unit. The substrate 190 has a plurality of first regions 191 and a plurality of second regions 192. The first anti-fouling material 110 is disposed in the first regions 191. The second anti-fouling material 120 is disposed in the second regions 192. The first anti-fouling material 110 and the second anti-fouling material 120 are not mixed, but are disposed in different regions. The first region 191 and the second region 192 of the embodiment are staggered. The first region 191 and the second regions 192 are arranged in a stripe-like staggered manner, and the width W191 of the first regions 191 is substantially equal to the width W192 of the second regions 192.
請參照第3圖，其繪示第2圖之抗污薄膜100之側視圖。透過第一抗污材料110的特性，可使位於其上之一液滴800形成一第一接觸角θ 1。同樣的，透過第二抗污材料120的特性，可使位於其上之液滴800形成一第二接觸 角θ 2。Referring to FIG. 3, a side view of the anti-fouling film 100 of FIG. 2 is shown. Through the characteristics of the first anti-fouling material 110, one of the droplets 800 located thereon can be formed to have a first contact angle θ 1 . Similarly, through the characteristics of the second anti-fouling material 120, the droplets 800 located thereon can be formed into a second contact. Angle θ 2.
在本實施例中，第一接觸角θ 1與第二接觸角θ 2並不相同。在本實施例中，第一接觸角θ 1大於第二接觸角θ 2。當液滴800位於第一區域191及第二區域192之交界處C時，透過液滴800在第一區域191及第二區域192之第一接觸角θ 1第二接觸角θ 2的差異，將對液滴800產生一股推擠力量。液滴800受到推擠將會朝接觸角較小的區域移動(例如是第二區域192)。In the present embodiment, the first contact angle θ 1 and the second contact angle θ 2 are not the same. In the present embodiment, the first contact angle θ 1 is greater than the second contact angle θ 2 . When the droplet 800 is located at the junction C between the first region 191 and the second region 192, the difference in the second contact angle θ 2 between the first contact angle θ 1 of the first region 191 and the second region 192 through the droplet 800, A push force will be generated on the drop 800. The pushing of the droplet 800 will move towards a region of lesser contact angle (e.g., the second region 192).
請參照第4圖，其繪示液滴800之移動示意圖。當大多數的液滴800朝向此區域集中時(例如是第二區域192)，將聚集成較大的液滴800。較大的液滴800會受到較大的重力，而容易滑落。請參照第5圖，其繪示指紋之油滴700之聚集示意圖。由左至右圖所示，油滴700受到推擠力量的推擠而容易聚集，聚集後的油滴700較容易觀察與擦拭。Please refer to FIG. 4, which illustrates a schematic diagram of the movement of the droplets 800. When most of the droplets 800 are concentrated toward this region (eg, the second region 192), larger droplets 800 will be aggregated. Larger droplets 800 are subject to greater gravity and tend to slip. Please refer to FIG. 5, which illustrates a schematic diagram of the aggregation of the oil droplets 700 of the fingerprint. As shown from the left to the right, the oil droplets 700 are easily pushed by the pushing force, and the collected oil droplets 700 are easier to observe and wipe.
常見的液滴800例如是水滴及油滴。研究人員針對水滴進行多次試驗，第一抗污材料110及第二抗污材料120之第一接觸角θ 1及第二接觸角θ 2範圍在90~120度時，對水滴有較佳的效果。在另一實施例之環境因素下，第一接觸角θ 1及第二接觸角θ 2範圍亦可以是100~120度。其中，研究人員更研究得到第一接觸角θ 1與第二接觸角θ 2之差在5~30度時，對於位於交界處C之水滴將產生足夠力量的推擠力量。在另一實施例之環境因素下，第一接觸角θ 1與第二接觸角θ 2之差亦可以是10~20度。Common droplets 800 are, for example, water droplets and oil droplets. The researcher performs multiple tests on the water droplets. When the first contact angle θ 1 and the second contact angle θ 2 of the first anti-fouling material 110 and the second anti-fouling material 120 range from 90 to 120 degrees, the water droplets are better. effect. In another environmental factor of the embodiment, the first contact angle θ 1 and the second contact angle θ 2 may also range from 100 to 120 degrees. Among them, the researchers have further studied that when the difference between the first contact angle θ 1 and the second contact angle θ 2 is 5 to 30 degrees, the pushing force that will generate sufficient force for the water droplets located at the junction C will be obtained. In another environmental factor of the embodiment, the difference between the first contact angle θ 1 and the second contact angle θ 2 may also be 10 to 20 degrees.
研究人員更針對油滴進行多次試驗，第一抗污材料110及第二抗污材料120之第一接觸角θ 1及第二接觸角θ 2範圍在50~80度時，對油滴有較佳的效果。在另一實施例之環境因素下，第一接觸角θ 1及第二接觸角θ 2範圍亦可以是60~80度。其中，研究人員更研究得到第一接觸角θ 1與第二接觸角θ 2之差在5~30度時，對於位於交界處C之油滴將產生足夠力量的推擠力量。在另一實施例之環境因素下，第一接觸角θ 1與第二接觸角θ 2之差亦可以是10~20度。The researcher further tests the oil droplets, and the first contact angle θ 1 and the second contact angle θ 2 of the first anti-fouling material 110 and the second anti-fouling material 120 range from 50 to 80 degrees, and the oil droplets have The better result. In another environmental factor of the embodiment, the first contact angle θ 1 and the second contact angle θ 2 may also range from 60 to 80 degrees. Among them, the researcher further studied that when the difference between the first contact angle θ 1 and the second contact angle θ 2 is 5 to 30 degrees, the pushing force of the oil droplets at the junction C will generate sufficient force. In another environmental factor of the embodiment, the difference between the first contact angle θ 1 and the second contact angle θ 2 may also be 10 to 20 degrees.
此外，基材190之粗糙度(Ra)也是影響接觸角之一因素。在本實施例中，基材190之粗糙度(Ra)小於50奈米(nm)。In addition, the roughness (Ra) of the substrate 190 is also a factor affecting the contact angle. In the present embodiment, the substrate 190 has a roughness (Ra) of less than 50 nanometers (nm).
一般而言，液滴800受到表面張力與內聚力的影響，液滴800將具有一定範圍的大小。請參照第6圖，其繪示液滴800與第一區域191及第二區域192之關係圖，當第一區域191及第二區域192之寬度W191、W192接近於液滴800之直徑W800時，液滴800很容易會位於第一區域191及第二區域192之交界處C，進而形成上述的推擠力量。In general, drop 800 is subject to surface tension and cohesion, and drop 800 will have a range of sizes. Please refer to FIG. 6 , which illustrates a relationship between the droplets 800 and the first region 191 and the second region 192 . When the widths W191 and W192 of the first region 191 and the second region 192 are close to the diameter W800 of the droplet 800 . The droplet 800 is likely to be located at the junction C of the first region 191 and the second region 192 to form the above-described pushing force.
請參照第7圖，其繪示液滴800與第一區域191及第二區域192之另一關係圖，當第一區域191及第二區域192之寬度W191、W192遠大於液滴800之直徑W800時，大部份液滴800不會位於第一區域191及第二區域192之交界處C，所以大部分的液滴800不會形成上述的推擠力量。Please refer to FIG. 7 , which illustrates another relationship between the droplet 800 and the first region 191 and the second region 192. When the widths W191 and W192 of the first region 191 and the second region 192 are much larger than the diameter of the droplet 800 At W800, most of the droplets 800 are not located at the junction C of the first region 191 and the second region 192, so most of the droplets 800 do not form the above-described pushing force.
請參照第8圖，其繪示液滴800與第一區域191及第 二區域192之另一關係圖，當第一區域191及第二區域192之寬度W191、W192遠小於液滴800之直徑W800時，大部份液滴800跨越多個第一區域191及第二區域192之交界處C。由於每一交界處C所形成之推擠力量係朝向接觸角較小的區域(例如是第二區域192)，所以相鄰的兩個交界處C係形成方向相反的推擠力量，而相互抵銷，故整體而言，第8圖之大部分的液滴800不會受到上述推擠力量的影響。Please refer to FIG. 8 , which shows the droplet 800 and the first region 191 and the In another relationship of the second region 192, when the widths W191, W192 of the first region 191 and the second region 192 are much smaller than the diameter W800 of the droplet 800, most of the droplets 800 span the plurality of first regions 191 and second. Junction C of area 192. Since the pushing force formed by each junction C is toward a region with a small contact angle (for example, the second region 192), the adjacent two junctions C form a pushing force in the opposite direction, and mutually resist each other. Pin, as a whole, the majority of the droplets 800 of Figure 8 are not affected by the above-described pushing force.
也就是說，研究人員研究發現當第一區域191及第二區域192之寬度W191、W192接近於液滴800之直徑W800時(如第4圖所示)，將使得液滴800被推擠的效果良好。此一寬度設計將產生特殊之效果，並非只是單純實施上的尺寸選擇。That is, the researchers have found that when the widths W191, W192 of the first region 191 and the second region 192 are close to the diameter W800 of the droplet 800 (as shown in FIG. 4), the droplet 800 will be pushed. The effect is good. This width design will have a special effect, not just a size choice for a simple implementation.
在一實施例中，大部分液滴800之直徑W800介於50~5000微米(μm)，故第一區域191及第二區域192之寬度W191、W192例如是介於50~5000微米(μm)。在另一實施例之環境因素中，大部分液滴800之直徑W800介於500~5000微米(μm)，故第一區域191及第二區域192之寬度W191、W192例如是介於500~5000微米(μm)。在另一實施例之環境因素中，大部分液滴800之直徑W800介於1000~5000微米(μm)，故第一區域191及第二區域192之寬度W191、W192例如是介於1000~5000微米(μm)。In one embodiment, the majority of the droplets 800 have a diameter W800 of 50 to 5000 micrometers (μm), so the widths W191 and W192 of the first region 191 and the second region 192 are, for example, 50 to 5000 micrometers (μm). . In another environmental factor of the embodiment, the diameter W800 of the majority of the droplets 800 is between 500 and 5000 micrometers (μm), so the widths W191 and W192 of the first region 191 and the second region 192 are, for example, between 500 and 5000. Micron (μm). In another environmental factor of the embodiment, the diameter W800 of the majority of the droplets 800 is between 1000 and 5000 micrometers (μm), so the widths W191 and W192 of the first region 191 and the second region 192 are, for example, between 1000 and 5000. Micron (μm).
就第一抗污材料110及第二抗污材料120而言，第一抗污材料110及第二抗污材料120係為氟化聚合物 (Fluoride Polymer)，例如是氟化有機矽烷聚合物(Fluoride Organosilane Polymer)，其化學式為RnSiX4-n。其中R基為不水解之氟化有機基團，R基可為氟烷(Fluoroalkyl)、氟化聚醚(Fluoropolyether)、全氟聚醚(Pre-fluoropolyether)、含環氧基、芳香族基團或其他含氟有機基團。第一抗污材料110及第二抗污材料120例如是氟化聚醚改質矽烷聚合物(Fluoropolyether-modified Silane Polymer)、全氟聚醚改質矽烷聚合物(Perfluoropolyether-modified Silane Polymer)、氟化烷基矽烷聚合物(Fluoralkyl-modified Silane Polymer)或全氟烷基矽烷聚合物(Perfluoralkyl-modified Silane Polymer)。For the first antifouling material 110 and the second antifouling material 120, the first antifouling material 110 and the second antifouling material 120 are fluorinated polymers. (Fluoride Polymer) is, for example, a Fluoride Organosilane Polymer having a chemical formula of RnSiX4-n. Wherein the R group is a fluorinated organic group which is not hydrolyzed, and the R group may be a fluoroalkane, a fluoropolyether, a perfluoropolyether, an epoxy group, an aromatic group. Or other fluoroorganic groups. The first antifouling material 110 and the second antifouling material 120 are, for example, Fluoropolyether-modified Silane Polymer, Perfluoropolyether-modified Silane Polymer, and fluorine. Fluoralkyl-modified Silane Polymer or Perfluoralkyl-modified Silane Polymer.
其中第一抗污材料110與第二抗污材料120可透過碳鏈長度來作設計，例如是第一抗污材料110之碳鏈長度大於第二抗污材料120之碳鏈長度。一般來說，碳鏈越長，其表面能越低、疏水性越佳、接觸角越大。The first anti-fouling material 110 and the second anti-fouling material 120 are designed to pass through the carbon chain length. For example, the carbon-resistant chain length of the first anti-fouling material 110 is greater than the carbon chain length of the second anti-fouling material 120. In general, the longer the carbon chain, the lower the surface energy, the better the hydrophobicity, and the larger the contact angle.
其中第一抗污材料110與第二抗污材料120可透過含氟原子數目之氟化程度來作設計，例如是第一抗污材料110之氟化程度高於第二抗污材料120之氟化程度。一般來說，氟化程度越高，其表面能越低、疏水性越佳、接觸角越大。The first anti-fouling material 110 and the second anti-fouling material 120 are designed to be fluorinated by the degree of fluorine atomic number, for example, the first anti-fouling material 110 is more fluorinated than the second anti-fouling material 120. Degree. In general, the higher the degree of fluorination, the lower the surface energy, the better the hydrophobicity, and the larger the contact angle.
