Through the touch panel. In addition, the upper surface of the conventional touch panel reflects ambient light. Therefore, in order to solve the problem of reflecting ambient light of the touch panel, an anti-reflection film (antjrefiecti〇n layer) is generally disposed on the upper surface of the touch panel, and the anti-reflection film is generally vacuum-sputtered or wet.

Second, the shape of the coating is limited due to the relationship of the coating material. 2nd, the process time is longer, which is not conducive to a large number of productions.

In addition, when the touch panel uses transparent plastic = reverse = 'cannite transfer technology (four) to directly coat a plurality of nano-structures on the touch panel, it can be mass-produced and large-area size production. 'Kazaki is a low birth. Furthermore, the nano-structure can be integrally formed on the touch panel without causing the problem of interface reflection. The above described features and advantages of the present invention will become more apparent from the following description. [Embodiment] Figs. 1 to 3 are schematic views of several touch devices according to a preferred embodiment of the present invention. In FIG. 1 to FIG. 3 , only a single film layer is schematically illustrated to represent a plurality of nano microstructures 120 ′ to illustrate the position of the nano microstructures 12 :: Referring first to FIG. 1 , the touch device 1 The touch panel 11A and the Xia nano microstructure 120 have opposite sides - a first side 112 and a second side 114. The nanostructures 12A are periodically arranged on the touch panel 110, and the nanostructures 12A are disposed on the first side 112 of the touch panel 11A. 9 201003481 -------206-0718 26801twf.doc/n The way in which the nano-structure 120 is set in Figure 2 and Figure 3 is similar to the setting in Figure i, except that the settings are different. Referring to FIG. 2, the 'nano microstructure 12' is disposed on the second side Π4 of the touch panel 110. Referring to FIG. 3 again, in the touch device 1〇4, the nano microstructures 120 are simultaneously disposed on the first side n2 and the second side 114 of the touch panel 11(). Since the above-mentioned periodically arranged nano-structure 120 adopts a single-layer sub-wavelength nano-structure, the light can be effectively penetrated from one side of the nano-structure 120, thereby reducing the incidence of ambient light. The scattering phenomenon and the increase of the transmittance of the surface light source. The following is a description of the embodiment of the nanostructure 12 及其 and its optical principle. 4A and 4B are partial schematic views of two nano microstructures in accordance with a preferred embodiment of the present invention. Referring first to Figure 4A, the nanostructures 120 are in a periodic arrangement, each of the nanostructures m having the shape of a prism on / and the nanostructures 120 being in a continuous arrangement. As shown in FIG. 4A, the pitch P between the ^ microstructures 120 is between 1 nanometer and 250 nanometers; the height of each nanostructure 120 is between 100 nanometers and 3 nanometers (8) nanometers. The outer nanostructure 12〇 shown in Fig. 4Β is similar to the nano microstructure 120 shown in Fig. 4α, and Guan Kun is too... as ^ion θ ^ . is different. As shown in Fig. 4Β The nano-small knots are not continuously arranged, that is, there is a gap between the two turns. In addition, it can also be called Figure 5, the shape of the nano-structure, the degree of Η is a round-shaped nano-structure 12 〇 = shaped nano-structure 12 . The spacing between the two is a heart, = α, forming a conical nano-structure 12〇, likewise, the height 201003481 ”A 206-07 丨8 26801 twf_doc/n Η is a conical nano-structure 120 The height between the two conical nanostructures 120 is Ρ. Of course, as long as the sub-wavelength nanostructure 12 尺寸 having a size close to the wavelength of light is used, the present invention is not limited to the nano-structure 120. The shape, for example, the pyramidal nano microstructure has a similar effect. Further, the pitch (Pitch) Ρ, height η, arrangement, and the like of the nanostructure 120 formed into an appropriate shape are as shown in Fig. 4 The embodiment shown in Fig. 4A is similar and will not be repeated here. (In view of the above, when the size of the nanostructure 120 is close to the nanometer level, the optical effect between the light and the nanostructure 120 changes. : In more detail, the wavelength of visible light is generally between 38 nanometers and 78 nanometers. However, the pitch P between the plurality of nanostructures 12 of the above embodiment is between 1 and 〇. 〇 nanometer ~25〇 nanometer; and each nanometer microstructure 120 The height η is between 100 nm and 3 Å. It is apparent that the size of the nano-structure 120 is smaller than the wavelength of visible light, thereby reducing the visible light from the environment between the nano-structures 12 〇. The probability of scattering phenomenon, and the nano-structure 丨2〇 is also suitable for the light from the surface light source to pass through. Therefore, the above-mentioned touch devices 1〇〇, 1〇2, 1〇4 can achieve the reduction of ambient light. The reflectivity and the effect of increasing the transmittance of the surface light source. _ The method for forming the above-mentioned nano microstructure 12〇 is, for example, a well-known micro-parameter process, anod oxidation or nano-turn The method is characterized in that the nano-structure 12 is formed on the touch panel 11A and is firstly thermoformed on the touch panel 11A. One of FIGS. 7A to 7C is a touch of the preferred embodiment of the present invention. The detailed structure diagram of the control device corresponds to the touch device of FIG. 3 to FIG. 3. The following is an example of the touch panel 110 as a capacitive touch panel at 11 26801 twf.doc/n 2010〇348L〇6,718. Please refer to FIG. 1 and FIG. 7A simultaneously. In the touch device 100, The micro-structure 120 is disposed on the first side 112 of the touch panel 110, and the touch panel 110 can include: a first substrate 112a, a first electrode pattern 114a, a dielectric layer 116, a second electrode pattern 114b, and a second substrate. Referring to FIG. 7A, the first substrate 112a is located on the first side 112. The first electrode pattern 114a is disposed on the first substrate U2a, and the second substrate 112b is located on the second side 114 and opposite to the first substrate 112a. The second electrode pattern 114b is disposed on the second substrate 112b, and the first electrode pattern 1 i4a and the second electrode pattern 114b are located between the first substrate U2a and the second substrate 112b. The touch panel 110 shown in FIG. 7A is a capacitive touch panel, so that a dielectric layer 116 is disposed between the first electrode pattern 114a and the second electrode pattern 114b. It should be noted that the nano-structure 12 is disposed on the first substrate 112a and on the opposite side of the first electrode pattern U4a. This day's surface light from the surface light source (not shown) under the touch panel 110, the line L1 can effectively penetrate the single-layer sub-wavelength nano-structure 12〇, and improve the surface light source L1 The penetration rate, which will be further explained in the subsequent Figure 8. In addition, as shown in FIG. 7A, in order to prevent the touch panel from being scratched, a hard cover layer 118 may be disposed above the first substrate 112b, and the hardness of the hard cover layer 118 may be utilized to avoid the user. Damage caused by long-term touch of the touch panel 100. Referring to FIG. 2 and FIG. 7B at the same time, the structure of the touch panel 12 201003481 .Z06-0718 26801 twf.doc/n 110 shown in FIG. 7 is the same as that of the touch panel 11 所示 shown in FIG. 7A . symbol. Referring to FIG. 7B 2 102, the nano-structure 120 is disposed on the opposite side of the second substrate U2b12 from the second electrode pattern 114b. Similarly, when the #第二(10)^ square is provided with the nanowire structure 12G, the hard mask layer 118 can be placed between the second earth plate 112b and the nanostructure 12〇. The ambient light from the outside can pass through the sub-wavelength nano-structure 12 without causing reflection.
