Description of the Invention: [Technical Field] The present invention relates to a touch panel, and more particularly to a capacitive touch panel. [Prior Art] FIG. 1 is a partial cross-sectional view showing a conventional capacitive touch panel. Referring to FIG. 1 , the capacitive touch panel 100 includes a substrate 11 , a first electrode pattern layer 120 , a second electrode pattern layer 130 , a dielectric layer 14 , and a protective layer 150 ′ The layer 120 and the second electrode pattern layer 130 are respectively composed of a plurality of first electrode patterns 122 and a plurality of second electrode patterns 132. As shown in FIG. 1 , the first electrode pattern layer 120 is disposed on the substrate ι1 而 and the dielectric layer 140 is interposed between the first electrode pattern layer 120 and the second electrode pattern layer 130 ′ wherein the first electrode pattern 122 , The two electrode patterns 132 and the dielectric layer 140 belong to a transparent conductive material and a transparent dielectric material, respectively. When the first electrode pattern layer 120 and the second electrode pattern layer 130 are respectively applied with appropriate voltages, a capacitive effect can be generated between the first electrode pattern 122 and the second electrode pattern 132. In practice, the first electric pattern 122 and the second electrode pattern 132 are generally formed using indium tin oxide (ITO). On the other hand, most of the current use of cerium oxide to form the dielectric layer 14 〇. As shown in FIG. 1 , when the display panel is located under the electric valley touch panel 100 and displayed, the light L of the display surface is incident from the lower surface of the substrate 110 of the capacitive touch panel, and faces the protective layer 150 . The direction penetrates the capacitive touch panel WP9702-C400-0766 28167twf.doc/n 100. At the position A, the light ray L passes through the first electrode pattern 122, the dielectric layer 140 and the protective layer 15 依 sequentially, and at the position b, the light ray sequentially passes through the dielectric layer 140 and the second electrode pattern 132. The position B on the protective layer 15 is further, and at c, the light L passes through the dielectric layer 14 and the protective layer 150 in sequence. ~ From the above, it can be seen that the light ray L is incident on the protective layer 150 from below the substrate 110, and does not pass through only one material. When the light L passes through the interface of different materials, physical phenomena such as refraction, reflection, and penetration occur, and the material forming the interface affects the degree of the physical phenomenon (degree of refraction, degree of reflection, degree of penetration). Etc.), so that the brightness of the light L after passing through position a, position b and position c is very different. Therefore, when the touch-sensitive display is displayed, the face seen by the human eye E may exhibit uneven brightness. In short, the characteristics and configuration relationship of each film layer in the capacitive touch panel 1 影 will affect the display quality of the touch display. SUMMARY OF THE INVENTION The present invention provides a capacitive touch panel, and the characteristics and arrangement relationship of each film layer in the capacitive touch panel contribute to the improvement of optical performance.

[Embodiment] FIG. 2 and FIG. 3 are respectively a partial top view and a partial cross-sectional view of a capacitive touch panel according to a first embodiment of the present invention. Wherein, Figure f is a cross-sectional view taken along line Χι_χ in Figure 2, and Figure 2 does not show the protective layer 250. 2 and FIG. 3, the capacitive touch panel 200 of the present embodiment includes a substrate 21G, a first electrode pattern layer 220, and a second electrode pattern layer. 230 and a dielectric structure 24". The first electrode pattern layer 22G and the second electrode pattern layer respectively include a plurality of first electrode patterns 222 and a plurality of second electrode patterns 232, wherein the first and second electrode patterns 222, 232 are transparent conductive materials f, for example The first electrode pattern 222 and the second electrode pattern 232 can be formed using indium tin oxide. However, the material selection of the first and second electrode patterns 222, 232 still depends on the actual production requirements, and the present invention does not limit the above materials. The dielectric structure 240 can be divided into a spacer portion 242 and a plurality of first compensation portions 244 connected to the interval 242, wherein the divisions of the portions * are based on the arrangement thereof, that is, the spacer portion of the embodiment 242 and the first compensation unit 244 may be of the same material. As shown in FIG. 2 and FIG. 3, in the embodiment, the first electrode pattern layer 220 is disposed on the substrate 21, and further, each of the first electrode patterns 222 of the first electrode pattern layer 220 is located on the substrate 210. Dielectric structure between *240. In addition, the spacer 242 of the dielectric structure 24 is substantially located between the first electrode pattern layer 220 and the second electrode pattern layer 230. When the first electrode pattern layer 22A and the second electrode pattern layer 23G are respectively applied with appropriate latitude, a capacitive effect can be generated between the first electrode pattern 222 and the second electrode pattern 232. In addition, a protective layer 250 is formed over the capacitive touch panel 200 to cover the second electrode pattern layer 23A. The first compensation portion 244 of the dielectric structure 24 of the present embodiment is opposite to the second electrode pattern 232 between the second electrode patterns 222 and the side surface of the first compensation portion 244 and the adjacent portion The side surfaces of one electrode pattern 222 are in contact. In detail, the first electrode pattern 222 and the second WP97〇2-C4〇〇^) 766 28167twf.d〇c/n^ pole pattern 232, for example, present a staggered arrangement of interconnections that are adjacent and do not overlap. The two portions of the second electrode pattern 222 are not finished = the substrate 210' is covered, and thus the region where the substrate 21 is ruptured by the first electrode pattern 222 can form a plurality of filling portions F1. The first compensation of dielectric structure 240, 244 is placed in these fill portions F1 + ' as shown in FIG. Further, the i-th compensation portion 244 may fill the filling portion π formed by the substrate 2ω and the first electrode pattern layer 220, and the first compensation portion 244 may correspond to the first electrode pattern 232. More specifically, in the present embodiment, the refractive index of the first electrode pattern 222 is close to the refractive index of the first compensating portion 244. (4) The spacer portion 242 and the first compensation portion 244 of the present embodiment are made of the same material, for example, and the refractive index of the dielectric structure 240 is substantially similar to the refractive index of the first electrode pattern 222. Further, from another point of view, the light path L passes through the first compensation portion 244, and the entire path length of the spacer portion 242 and the second electrode pattern 232 is very close to the thickness d1. Similarly, the light L is longer by the entire path of the first electrode pattern 222 and the spacer 242 and the entire path length of the first compensation portion 244 and the spacer 242 is also very close to the thickness. Therefore, the light L can still exhibit similar properties after passing through the position A, the position B, and the position c. In this way, after the light L passes through the position A, the position B, and the position c, the optical effects such as refraction and reflection of the light L can be regarded as being equal. Thus, the capacitive touch panel 200 can provide relatively good optical penetration under the configuration of the dielectric structure 24A. Specifically, when the light L is incident from the lower surface of the substrate 210 to the protective layer 250, the light L passing through the position a passes through the first electrode pattern 1380208 WP9702-C400-0766 28167twf.doc/n 222 and the dielectric structure 24 in sequence. The spacer portion 242 of the crucible, the light red passing through the position b passes through the first compensation portion (10) and the inter-242 and the second electrode pattern 232' in the dielectric structure 240 through the light L passing through the position c through the dielectric structure 240. The first compensation portion of the ice and the spacer portion 244 and the spacer portion 242 are, for example, opposite in refractive index, close to the refractive index of the first electrode pattern and the second electrode pattern 232, and the first electrode pattern 222 and the interval The portion 242 of the electrical structure 240 and the light ray L pass through the dielectric pattern 232. ^Electricity,,,. For the structure 240 and the second electrode, the difference in refractive index between the first electrode 222 and the second electrode pattern 例如 is, for example, at least smaller than the first electrode made of indium tin oxide, so that the refractive index is substantially A material of approximately 2.06 is used to fabricate the dielectric structure 240, such as a refractive index: ί, an organic material between 1.55 and 2.5, substantially in between;; == C brain 2), and pentoxide (Nb2〇5) := Give equal dielectric materials. However, the refractive index of the real material f is too numerous to enumerate, and is not listed here. " pole figure (2); the difference between the refractive index of the τ dielectric structure 240 and the first-electron is at least less than 0 宽! 7=, the difference between the examples is the dielectric material with a similar refractive index and the electrocardiogram = 2 8 1380208 WP9702-C400-0766 28l67twf.d〇c/n • ^ into " electrical structure 240 and second electrode pattern 222/232. In other embodiments, when the thickness dl of the spacer 242 of the dielectric structure 24 is substantially greater than 5.5 micrometers (micrometers), the light rays L sequentially pass through the dielectric structures 24() and the second The electrode pattern is damaged in time. The total energy consumed is substantially the same as the energy lost when the light L passes through the spacer 242. Since the energy of the light is reflected in the brightness representation, the brightness of the light L sequentially passing through the dielectric structure and the second electrode pattern is substantially the same as the brightness of the light L passing through the spacer 242. In the example of Benedict, the ray L is sequentially visible through the first electrode pattern 222 and the spacer 242 as the light ray L passing through the spacer 242, and the light ray 1 is also visible through the dielectric structure 240 and the second electrode pattern 232. The light ray L passes through the spacer 242. In other words, when the light L is incident from the substrate 21A to the protective layer 250, it can be considered that the light L travels in a uniform material. As a result, the capacitive touch panel 2 can provide relatively good optical penetration. It can be seen from the above that the capacitive touch panel 2 应用于 is applied to the touch display, which can improve the brightness uniformity of the touch display, and the touch display has good display quality. [Second Embodiment] FIG. 4 is a partial cross-sectional view showing a capacitive touch panel according to a second embodiment of the present invention. Referring to FIG. 4, the capacitive touch panel 400 of the present embodiment is similar to the capacitive touch panel 200 of the first embodiment, wherein the same or similar reference numerals respectively denote the same or similar components, and the description thereof will not be repeated. The main difference between the two is that the capacitive touch panel 400 of the present embodiment may further include a plurality of second compensation portions 446 ′ connected to the spacers 442 and the material of the spacers 422 is different from the first compensation portion of the tree 9 1380208 WP9702 -C400-0766 28167twf.doc/n # ^ The thickness of the spacer 442 may be unlimited. As shown in FIG. 4, in this embodiment, the arrangement of the dielectric structure _ can be referred to the related description of the first embodiment, and details are not described herein. The second compensation portion 446 is located in the second electrode pattern 232.

It can be effectively obtained from the above that the light [2 ==: interface and the second compensation portion 44: = the refractive index of the second electrode pattern 232 is approximately equal to the refractive index of the second compensation portion, thereby effectively reducing the The optical of the second interface, in this embodiment, the difference in refractive index of the refractive index-reconciliation portion 444 of the first electrode pattern is at least less than 〇5, and the refractive index of the second pole pattern 232 and the second compensation portion The difference in refractive index is two, and the light ray L can be regarded as the ϋ-compensation portion 444 through the first electrode pattern 222, and the ray L passes through the second electrode pattern, the = position A, the position Β and the refraction after the position c, The reflective 荨 optical side is roughly phase _. In this way, capacitive touch is a good optical property. Capacitive touch panel ‘ ^The integration of the panel into a touch-sensitive display panel allows the touch-sensitive display panel to display a good display. The electrode ' is exemplified by the first/second electric and pattern 22 of the indium tin oxide, and the second second compensation portion 446 of the indium tin oxide can be selected by using a material having a refractive index close to (10). For example, a dielectric material such as an organic substance or an oxide having a refractive index substantially between 155 and 2.5, preferably, for example, a refractive index substantially 11 1J0UZU5 WP9702-C400-0766 28167twf.d〇c/, and the material therebetween includes dioxide Give (_, five: and: oxidized two groups (10) 5) and other dielectric materials.

However, in other solid wipes, it is also possible to use a dielectric (4) and a dielectric material that are more similar to each other to form the "compensation part 444 and the first electrode pattern 222, respectively, or to select a medium with a similar refractive index.

由於，光線L在電容式觸控面板4〇〇中所受的的介 面作用已藉由介電材料的選用而獲得適當補償。因此， 間隔部442的厚度d2並不必為了避免光線l在行進中發 生路徑長度不均等的情形而受限於特定值。換言之，本 實施例之間隔部442的厚度d2並不會影響光線L在不同 的路徑上所受的變化。因此，本實施例之間隔部442的 厚度d2具有可調性。然而，當間隔部442的厚度d2越 小時’電容式觸控面板400的整體厚度也會隨之降低， 因而電容式觸控面板400具有薄型化之優勢。 由上述可知，將電容式觸控面板400應用於觸控式 顯示器中’可提升該觸控式顯示器的亮度均勻度，亦使 12 1380208 WP9702-C400-0766 28167twf.doc/n : 該觸控式顯示器具有薄型化之優勢。 综上所述，本發明之電容式觸控面板中的介 . 具有補償部，用以使電容式觸控面板呈現的均 度。將本發明之電容式難面板躺於— =器中，可使該觸控式顯示器所顯示的畫面具有的 亮度，進而呈現良好的對比表現。整體而言，本笋^、 電容式觸控面板可有效提升觸控式顯示器的顯示品"質。之 雖然本發明已以較佳實施例揭露如上，然其1非用 • 以限定本發明，任何所屬技術領域中具有通常知識者， 在不脫離本發明之精神和範圍内，當可作些許之更動與 /閏飾’因此本發明之保護範圍當視後附之申請專利範圍 所界定者為準。 【圖式簡單說明】 圖1繪示習知一種電容式觸控面板的局部剖面示意 圖。 Φ 圖2繪示本發明之第一實施例之電容式觸控面板的 局部上視示意圖。 圖3繪示本發明之第一實施例之電容式觸控面板的 局部剖面示意圖。 圖4繪示本發明之第二實施例之電容式觸控面板的 局部剖面示意圖。 13 1380208 WP9702-C400-0766 28167twf.doc/nSince the interface of the light L in the capacitive touch panel 4 is already properly compensated by the selection of the dielectric material. Therefore, the thickness d2 of the spacer 442 does not have to be limited to a specific value in order to prevent the light 1 from being uneven in path length during traveling. In other words, the thickness d2 of the spacer 442 of the present embodiment does not affect the variation of the light ray on different paths. Therefore, the thickness d2 of the spacer 442 of the present embodiment has adjustability. However, when the thickness d2 of the spacer portion 442 is small, the overall thickness of the capacitive touch panel 400 is also lowered, so that the capacitive touch panel 400 has the advantage of being thinned. As can be seen from the above, the use of the capacitive touch panel 400 in a touch-sensitive display can improve the brightness uniformity of the touch-sensitive display, and also enables 12 1380208 WP9702-C400-0766 28167twf.doc/n: the touch type The display has the advantage of being thin. In summary, the capacitive touch panel of the present invention has a compensation portion for making the capacitive touch panel appear uniform. By placing the capacitive hard panel of the present invention in the -= device, the brightness of the picture displayed by the touch display can be made to show a good contrast performance. Overall, the capacitive touch panel can effectively improve the display quality of the touch display. Although the present invention has been disclosed in the above preferred embodiments, the present invention is not intended to be limited thereto, and any one of ordinary skill in the art can make some modifications without departing from the spirit and scope of the invention. The scope of protection of the present invention is therefore defined by the scope of the appended claims.
