In order to provide a clearer description and easier understanding of the technical features of this creation, the various parts in the drawings are not drawn according to their relative dimensions. Some dimensions are different from others. The relative scale has been exaggerated; the irrelevant details have not been completely drawn, in order to simplify the diagram.

參閱圖1所示，本創作實施例的觸控顯示裝置的面板10包含一基板100及一塗層200；該面板10被配置於觸控顯示裝置20前方使用。Referring to FIG. 1, the panel 10 of the touch display device of the present creative embodiment includes a substrate 100 and a coating 200; the panel 10 is disposed in front of the touch display device 20 for use.

其中，基板100採用透明的鈉鈣矽酸鹽玻璃，在該基板100觸摸側的頂表面上佈滿許多微米級尺寸大小的凸出體110，該等凸起狀的凸出體110可能以規格化或以非規格化方式排列而佈滿整個基板100的頂表面；如圖3至圖5所示的實施例中，凸出體110為錐體構型，但在實際的應用中該凸出體110也可以是柱體110’(如圖6所示)、半球體、島嶼型體、香菇型體或其他不規則形狀凸出體；相鄰的二個凸出體110彼此的間隔D約在1µm至20µm的範圍，而且該等凸出體110在其基底部位彼此相連接以共同構成一凹谷120，該凸出體110的頂部至該凹谷120的底部的高度差H約在0.5µm至10µm的範圍；因此，在基板100的整個頂表面由該等凸起的凸出體110與該等下凹的凹谷120彼此交替而分布，形成一類似於蛾眼結構(moth-eye structure)；如圖8所示，前述仿真蛾眼結構的表面為一凹凸不平的啞光無反射表面，可使波長在360nm至830nm範圍的光線產生散射和漫反射作用，降低反射並獲得防眩暈、防刺眼功效，以達到提升可瞻性的目的；此外，該仿真蛾眼結構有類似蓮花效應(lotus effect)之疏水特性，可提高基板100頂表面的防污及自潔效能。Wherein, the substrate 100 is made of transparent soda lime silicate glass, and the top surface of the touch side of the substrate 100 is covered with many micron-sized protrusions 110. The protrusions 110 may be in specifications. Or arranged in a non-standardized manner to cover the entire top surface of the substrate 100; in the embodiment shown in FIG. 3 to FIG. 5, the protrusion 110 has a cone configuration, but in actual applications, the protrusion 110 is in a cone configuration. The body 110 can also be a column 110' (as shown in FIG. 6), a hemisphere, an island-shaped body, a mushroom-shaped body or other irregularly shaped protrusions; the distance D between two adjacent protrusions 110 is about In the range of 1 µm to 20 µm, and the protrusions 110 are connected to each other at their bases to form a valley 120 together. The height difference H from the top of the protrusion 110 to the bottom of the valley 120 is about 0.5 µm to 10 µm; therefore, on the entire top surface of the substrate 100, the raised protrusions 110 and the recessed valleys 120 are alternately distributed to form a moth-eye structure (moth-eye). structure); As shown in Figure 8, the surface of the aforementioned simulated moth-eye structure is an uneven matte non-reflective surface, which can scatter and diffuse reflection of light with a wavelength in the range of 360nm to 830nm, reduce reflection and obtain anti-glare , Anti-glare effect, in order to achieve the purpose of improving visibility; in addition, the simulated moth-eye structure has a hydrophobic characteristic similar to the lotus effect, which can improve the anti-fouling and self-cleaning performance of the top surface of the substrate 100.

如圖2所示，在基板100表面形成前述仿真蛾眼結構或是啞光無反射表面，可應用多種技術手段製成，例如以混酸溶液對基板100的鈉鈣矽酸鹽玻璃進行化學蝕刻，以去除表面較軟材料的部分，使基板100的頂表面形成由多數錐體與凹谷交替分布的粗糙面結構；該混酸溶液的成份可包含氫氟酸(HF)、硫酸(H 2SO 4)、鹽酸(HCl)、醋酸(CH 3COOH)、氟化銨(NH 4F)等，但不以上述材料為限。除了上述化學蝕刻法之外，其他可行的加工手段還包含模板法、電化學方法、化學氣相沉積法等。 As shown in FIG. 2, the aforementioned artificial moth-eye structure or matt non-reflective surface is formed on the surface of the substrate 100, which can be made by various technical means, such as chemical etching of the soda lime silicate glass of the substrate 100 with a mixed acid solution. In order to remove the part of the softer material on the surface, the top surface of the substrate 100 forms a rough surface structure with a large number of cones and valleys alternately distributed; the components of the mixed acid solution may include hydrofluoric acid (HF), sulfuric acid (H 2 SO 4 ), hydrochloric acid (HCl), acetic acid (CH 3 COOH), ammonium fluoride (NH 4 F), etc., but not limited to the above materials. In addition to the above-mentioned chemical etching method, other feasible processing methods also include template method, electrochemical method, chemical vapor deposition method and so on.

此外，該基板100還包含在前述凸出體110的表面上分布有銀離子Ag +以形成一具有抗菌效能的表面，以及在基板100的表面具一壓應力層130；在本實施例中，該壓應力層130的深度約為10µm，壓應力值約為400MPa；如所知的，當壓應力層的深度越深、壓應力值越大，則該基板100的板體強度越佳。參閱圖2所示，前揭所述的在基板100表面形成含銀離子抗菌效果及強化處理的製作手段，可通過使用硝酸銀(AgNO 3)與硝酸鉀(KNO 3)的混成熔鹽進行離子交換的方法達成，其具體實施方式包含：(1)將該具有鹼金屬離子的玻璃基板與被加熱至350攝氏度至600攝氏度的氯化銨(NH 4Cl)進行脫鹼處理，玻璃基板中的鈉離子Na +在溫度升高的時候遷移性強，並且與氯化銨分解出的氫離子H +交換；(2)再將該玻璃基板與被加熱至約380攝氏度的硝酸銀(AgNO 3)與硝酸鉀(KNO 3)的混成熔鹽進行離子交換；其中，前述混成熔鹽中的硝酸鉀(KNO 3)重量比為95%~99.99%、硝酸銀(AgNO 3)重量比為0.01~5%；使混成熔鹽中的鉀離子K +、銀離子Ag +取代玻璃基板上鈉離子Na +，從而使銀離子Ag +分布到該玻璃基板的表面，形成一具有抗菌效能的表面；此外，由於玻璃基板上的鈉離子Na +被較大型離子的鉀離子K +置換取代，因此在玻璃基板的表面形成一抵抗拉應力的壓應力層，實現了玻璃強化的目的；通過前述離子交換的製備手段可在基板100表面形成抗菌及強化效果，強化後的玻璃板體依然具有優異的被切割、外型加工能力，且基板100沒有傳統的抗菌處理後產生色變的問題，實驗結果表明，其抗菌測試JIS2801大腸桿菌的抗菌值達到5以上、黃金葡萄球菌的抗菌值達到3.8~4.7以上；另外，特別值得一提的，本創作的基板表面是先經過化學蝕刻形成抗眩光結構後再進行離子交換形成抗菌表面，基板表面通過化學蝕刻形成抗眩光結構的同時已倍增了該基板表面的表面積，因此隨後進行的離子交換製程可在該基板表面上分布更多銀離子Ag +，從而本創作的基板上的抗菌表面具有加強的抗菌效能。 In addition, the substrate 100 further includes silver ions Ag + distributed on the surface of the aforementioned protrusion 110 to form a surface with antibacterial effect, and a compressive stress layer 130 on the surface of the substrate 100; in this embodiment, The depth of the compressive stress layer 130 is about 10 μm, and the compressive stress value is about 400 MPa; as known, the deeper the compressive stress layer is, the greater the compressive stress value is, the better the plate strength of the substrate 100 is. Referring to FIG. 2, the method of forming silver ion-containing antibacterial effect and strengthening treatment on the surface of the substrate 100 described in the previous disclosure can be performed by using a mixed molten salt of silver nitrate (AgNO 3 ) and potassium nitrate (KNO 3) for ion exchange The method is achieved, and the specific implementation includes: (1) Dealkalizing the glass substrate with alkali metal ions and ammonium chloride (NH 4 Cl) heated to 350 degrees Celsius to 600 degrees Celsius, the sodium in the glass substrate The ion Na + has strong mobility when the temperature rises, and exchanges with the hydrogen ion H + which is decomposed by ammonium chloride; (2) Then the glass substrate is heated to about 380 degrees Celsius with silver nitrate (AgNO 3 ) and nitric acid The mixed molten salt of potassium (KNO 3 ) performs ion exchange; wherein the weight ratio of potassium nitrate (KNO 3 ) in the aforementioned mixed molten salt is 95%-99.99%, and the weight ratio of silver nitrate (AgNO 3) is 0.01-5%; The potassium ions K + and silver ions Ag + in the mixed molten salt replace the sodium ions Na + on the glass substrate, so that the silver ions Ag + are distributed on the surface of the glass substrate to form a surface with antibacterial effect; in addition, due to the glass substrate The sodium ion Na + on the surface is replaced and replaced by the larger ion potassium ion K + , so a compressive stress layer that resists tensile stress is formed on the surface of the glass substrate to achieve the purpose of glass strengthening; the aforementioned ion exchange preparation method can be used in The surface of the substrate 100 forms an antibacterial and strengthening effect. The strengthened glass body still has excellent cutting and appearance processing capabilities, and the substrate 100 does not have the problem of discoloration after the traditional antibacterial treatment. The experimental results show that its antibacterial test is JIS2801 The antibacterial value of Escherichia coli is above 5, and the antibacterial value of Staphylococcus aureus is above 3.8~4.7; in addition, it is particularly worth mentioning that the surface of the substrate in this creation is first chemically etched to form an anti-glare structure and then ion exchange to form an antibacterial The surface of the substrate is chemically etched to form an anti-glare structure, and the surface area of the substrate surface has been doubled. Therefore, the subsequent ion exchange process can distribute more silver ions Ag + on the surface of the substrate. The antibacterial surface has an enhanced antibacterial effect.

The coating 200 is a hydrophobic material containing antibacterial and antibacterial ingredients. The antibacterial and antibacterial ingredients are nano silver, nano One or more mixtures of rice zinc, organic/inorganic antibacterial composite materials, and the hydrophobic material is selected from, for example, fluorosilicone polymer, polytetrafluoroethylene, fluorocarbon, silicone-containing compound or paraffin wax, etc.; coating 200 The coating surface includes the surface of the protrusions 110 and valleys 120 in the aforementioned artificial moth-eye structure or matte non-reflective surface, so that the surface tension of the coating surface is minimized, and the surface contact area of the dust and the coating surface is greatly reduced , So it has strong hydrophobicity, oil stain resistance, and fingerprint resistance; the coating thickness of the coating 200 should not be too thick, preferably less than 0.2μm, preferably less than 0.02μm, so as to avoid damage or This adversely affects the performance of the moth-eye structure; on the other hand, since the artificial moth-eye structure originally formed on the top surface of the substrate 100 already has a hydrophobic characteristic similar to the lotus effect, plus this coating The hydrophobic effect of the layer 200 causes the water contact angle on the top surface of the substrate 100 to exceed 115°, thereby compounding the antifouling and self-cleaning effects of the top surface of the substrate 100; in addition, the coating 200 is evenly distributed with antibacterial and sterilization properties. Ingredients, so that the coating 200 has an excellent antibacterial and sterilization effect.

綜上所述可知，本創作所提供的觸控顯示裝置的面板同時兼具有抗眩光、強化、抗指紋以及雙重抗菌的效果，該雙重抗菌功能包含形成在該基板100頂表面上的銀離子Ag +的抗菌表面，以及均勻分布在該塗層200中的抗菌殺菌成份，即便是在面板的使用歷程中，當該塗層200自該基板100的頂表面脫落時，形成在該基板100頂表面上的銀離子Ag +的抗菌表面仍能正常發揮功效，使觸控顯示裝置的面板長期保持抗菌殺菌效果。 To sum up, it can be seen that the touch display device panel provided by this creation has the effects of anti-glare, strengthening, anti-fingerprint and dual antibacterial. The dual antibacterial function includes silver ions formed on the top surface of the substrate 100.
