Description of the Invention: [Technical Field] The present invention relates to a touch panel and in particular 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 110 , a first electrode pattern layer 120 , a second electrode pattern layer 130 , a dielectric layer 140 , and a protective layer 15 , wherein the first electrode pattern layer 12 . The 〇 and the first electrode pattern layers 130 are composed of a plurality of first electrode patterns 122 and a plurality of second electrode patterns 132, respectively. As shown in FIG. 1 , the first electrode pattern layer 120 is disposed on the substrate 11 而 and the dielectric layer 140 is interposed between the first electrode pattern layer 120 and the second electrode pattern layer 13 ' The second electrode pattern m is in the 'two; | the electrical layer 140 belongs to the transparent conductive material and the transparent dielectric material, respectively. When the first electrode pattern layer 120 and the second electrode pattern layer 130 respectively apply an appropriate voltage, a capacitive effect can be generated between the first electrode pattern 122 and the second electrode pattern 13i. In practice, the first electrode pattern 122 and the second electrode pattern 132 are generally formed using indium tin oxide (ITO). On the other hand, the dielectric layer 140 is mostly made of yttrium oxide. As shown in FIG. 1 , when the display panel is located under the electric touch panel 100 and displayed, the light green L of the display is incident on the bottom of the substrate 110 of the capacitive touch panel 100 and faces the protective layer. The direction of 150 penetrates the capacitive touch panel 3 201035837 WP9702-C400-0766 28167twf.doc/n 100. At position A, the light ray sequentially passes through the first electrode pattern 122, the dielectric layer 140, and the protective layer 150'. At the position B, the light ray sequentially passes through the dielectric layer 140, the second electrode pattern 132, and the protection. The position B on the layer ι5 ,, and at C, the light ray sequentially passes through the dielectric layer 14Q spot protection layer 150. From the above, it can be seen that the light ray L is incident on the protective layer 150 from below the substrate ho, and does not pass through only one material. When the light passes through the interface of the material, 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, wear). The degree of penetration, etc., so that the brightness exhibited by the light L passing through the position A, the position B, and the position c is greatly different. Therefore, when the touch-sensitive display is displayed, the screen seen by the second eye E may exhibit uneven brightness. In short, the characteristics and arrangement relationship of the respective film layers in the touch panel 100 are combined with the display quality of the touch display. For example, the present invention provides a capacitive touch panel, and the characteristics and configuration relationship of each of the layers of the capacitors are used to enhance the light g to specifically describe the content of the present invention. The capacitive touch panel includes a one-tenth type electric contact surface electrode pattern. The second electrode pattern layer is provided with a plurality of second patterns == set--"structure::" board" wherein the first electrode pattern layer comprises a plurality of layers 201035837 WP9702-C400-0766 28167twf.doc/n electrical structure - Coffee Department and Township Department. The spacer is located between the first and the second layer === compensation. The first compensating portion is located at the first electric/the = layer: the side surface of the compensating portion of the qingying-di-compensation portion is in contact with the side surface of the adjacent: case. The first-thunder electrode pattern and the fold structure of the first electrode pattern are at least less than 0.5. H private material refractive index difference 〇 In the present invention, the second compensation side is connected to the partition. The flute_fu is again, and there is a difference between the eclipse and the first electrode pattern !=: The refractive index difference of the pattern is at least less than 〇.5. In the present invention, the characteristics of these compensation parts and the unevenness of the brightness of the earth, the mouth, and the second-in-one compensation are improved. I 板板 ο The capacitive touch panel will be described in detail in the embodiment: the above characteristics and advantages of the genius electric secret can be more clearly understood 'below, the cow is better _, and with the drawing, A detailed description is as follows. [Embodiment] [First Embodiment] Fig. 3 and Fig. 3 show a schematic top view and a partial cross-sectional view of a capacitive portion of a first embodiment of the present invention. Among them, painted Na 250. The cross-section of the d f line is ' and the figure 2 is not. (9) Referring to FIG. 2 and FIG. 3, the power supply 5 201035837 WP9702-C400-0766 28167 twf.doc/n of the present embodiment includes a substrate 210, a first electrode pattern layer 220, and a second electrode pattern. Layer 230 and a dielectric structure 240. The first electrode pattern layer 220 and the second electrode pattern layer 230 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 and 232 are transparent conductive materials, for example, The first electrode pattern 222 and the second electrode pattern 232 may be formed using indium tin oxide. However, the material selection of the first and second electrode patterns 222, 232 still depends on the needs of the actual product, and the present invention is not limited to 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 division principle of the portions is based on the configuration thereof, that is, the spacer portion 242 of the embodiment is 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 21 . Between the crucible and the dielectric structure 240. Further, the spacer 242 of the dielectric structure is substantially between the first-electrode layer (10) and the second electrode pattern layer 23G. When the first electrode pattern layer 220 and the second electrode pattern layer 23G are respectively applied with appropriate voltages, a capacitive effect can be generated between the first electrode pattern 222 and the second electrode pattern. In addition, a protective layer 250 is formed on the capacitive touch panel 2 (8) to cover the second electrode pattern layer 23A. / The side surface of the first compensating portion 244 and the adjacent first electrode pattern between the first compensating portion 244 and the drain pattern 222 of the dielectric structure 240 of the present embodiment and corresponding to the second electrode pattern 232 'Bei 1 surface contact. In detail, the first electrode pattern 222 and the second 201035837 WP9702-C400-0766 28167 twf.doc/n electrode pattern 232, for example, exhibit a staggered arrangement in which the interconnects are contiguous and do not overlap. On the other hand, the first electrode pattern 222 does not complete the substrate 210, and thus the region where the substrate 2 is rotated by the first electrode pattern 222 can form a plurality of filling portions π. The first portion 244 of the dielectric structure 24 is disposed in the filling portion π as shown in FIG. The first compensation unit 244 can fill the filling portion F1 formed by the substrate 21 () and the second layer 220, corresponding to the second electrode pattern 232. 4 _ partial tearing can be compared with the first refractive index, The refractive index of the 'electrode pattern 222' of the electrode pattern 222 is similar. Iron, for example, the spacer 242 and the first compensation portion 244, the refractive index of the dielectric structure 240 is substantially = 疋, Material, the pole figure? 〇〇ea Light L passes through the first electric part 2^ m The overall path length of the partition and the length of the first compensation is also (4) close to the thickness = push position A, position B and position c = The similar nature. So - the light L line longitude = large and position C, the light: the refraction, the reflection of the position can be: ! is equal. Therefore, the distribution of the dielectric structure 240 = The various touch panels 200 can provide a relatively good optical body. When the light L passes from the substrate 21G, the light L passing through the position A passes through the 7th 201035837 WP9702-C400-0766 28167twf.d〇 The spacer 242 of the c/n 222 and the dielectric structure 240 passes through the 帛 and the light L· in the dielectric structure 240 in sequence. The first compensation portion of the dielectric structure is in the order of the first electrode pattern 222 and the spacer portion 242. The power supply structure 24 〇 and the light L pass through the dielectric and the dielectric pattern 232. The Fu and the second electrodes are practical, the first electrode pattern 222 and the two shots, one compensation unit ~ .5 in the other In the example, the indium tin oxide is used in the fabrication of the capacitive touch panel, so that the dielectric structure is formed, for example, the organic material or the oxidation between the refractive index and the cathode is between 55 and 25. Dielectric materials such as materials! Goodly, for example, the refractive index is substantially between 17 and 1:1, 'better (_2), pentoxide: 铌(10) five:: electrical materials. However, the refractive index is essentially a dielectric material, In the embodiment, the refractive index of the dielectric structure 240 is 盥1 玉 222 and the second electrode 232; the electric power is at least less than 〇5 丄 refractive index. An example of the difference between a dielectric material with a refractive index and a transparent conductive material is $201035837 WP9702-C400-Q766 2 8167twf.doc/n forms dielectric structure 240 and first/second electrode pattern 222/232.

線L依序通過介電結構施及第二電極圖案232時所損 耗的整體能量便與光線L通過間隔部242時所損耗的能 量大致相同。由於光量大小會反應在亮度表現上, 因此光線L依序通過介電結構24()及第4極圖案说 後的亮度會與光線L通過間隔部242㈣亮度大致相同。 在本實施例中,光線L依序通過第一電極圖案222 與間隔部242可視為光線L通過間隔部242,而光線L 依序通過介電結構24G和第二電極圖案232也可視為光 線L通過間隔部242。換句話說’當光線L自基板21〇 下方入射至保護層250日夺’可視為光線L在均句的材質 中行進。如此一來,電容式觸控面板2〇〇可提供相當良 好的光學穿透性。由上述可知’將電容式觸控面板2〇〇 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,進而使該觸控式顯示器具有良好的顯示品質。 【第二實施例】 圖4繪π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。明參照圖4,本實施例之電容式觸控面 板400與第一實施例之電容式觸控面板2〇〇相似,其中 相同或相似的標號分別代表相同或相似的構件,在此不 重複說明。二者主要差異在於:本實施例之電容式觸控 面板400可進一步包括多個與間隔部442相連的第二補 償部446 ’而間隔部422之枒質不同於第一補償部4糾之 201035837 WP9702-C400-0766 28167twf.doc/n 材質’且介電結構440之間隔部442㈤厚度可不受限制。 如圖4所示,在本實施例中,介電結構44 。 f㈣444的排列方式可參考第一實施例之相關說日^ 在不加以贅述。第二補償部446位於第二電極圖案 之間並與第-電極圖案222相對應,且第二補償部 的側表面與相鄰之第二電極圖案232的側表面接觸 細而言’第-電極圖案222和第二電極圖案232例^ Ο 疊,列方式。另—方面’第二電極圖 亚凡王覆蓋間隔部442’因而間隔部442與第— 電極圖案232可形成多個對應於第-電極圖案222、的^ 充部F2,介電結構44〇之第二補償部4牝則配置在這些 填充邛F2中。第二補償部446可填滿間隔部與第二 電極圖案232所構成的填充部F2,且第二補償部446 ^ 可與第一電極圖案222相對應。 °The total energy lost by the line L when the second electrode pattern 232 is applied through the dielectric structure is substantially the same as the energy lost when the light L passes through the spacer 242. Since the amount of light is reflected in the brightness expression, the brightness of the light L sequentially passing through the dielectric structure 24() and the fourth pole pattern is substantially the same as the brightness of the light passing through the spacer 242 (4). In this embodiment, the light ray L can be regarded as the light ray L passing through the spacing portion 242 through the first electrode pattern 222 and the spacing portion 242, and the light ray L can also be regarded as the light ray through the dielectric structure 24G and the second electrode pattern 232. Passing 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 regarded as the light L traveling in the material of the uniform sentence. 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 thus the touch display has good display quality. [Second Embodiment] Fig. 4 is a partial cross-sectional view showing a capacitive touch panel of 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 2 of the first embodiment, wherein the same or similar reference numerals respectively denote the same or similar components, and the description is not repeated here. . 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 interface 422 is different from the first compensation portion 4 for correcting 201035837. WP9702-C400-0766 28167twf.doc/n The thickness of the spacer 442 (5) of the material 'and the dielectric structure 440 is not limited. As shown in FIG. 4, in the present embodiment, the dielectric structure 44. For the arrangement of the f(four) 444, refer to the related description of the first embodiment, and the details are not described herein. The second compensation portion 446 is located between the second electrode patterns and corresponds to the first electrode pattern 222, and the side surface of the second compensation portion is in contact with the side surface of the adjacent second electrode pattern 232. The pattern 222 and the second electrode pattern 232 are stacked and arranged in a column manner. On the other hand, the second electrode yawangwang covers the spacer 442'. Thus, the spacer 442 and the first electrode pattern 232 can form a plurality of filling portions F2 corresponding to the first electrode pattern 222, and the dielectric structure 44 The second compensation unit 4牝 is disposed in these fillings F2. The second compensation portion 446 may fill the filling portion F2 formed by the spacer portion and the second electrode pattern 232, and the second compensation portion 446^ may correspond to the first electrode pattern 222. °
如圖4所不,當光線L行經位置Α並依序通過第一 電極圖案222和間隔部442時,於第一電極圖案222和 ❹ 間隔部442之間的界面所發生的折射現象會改變光線L 光學特性,例如光線L的反射程度、穿透程度、亮度 等。同樣地,當光線L行經位置B並依序通過第一^償 部444和間隔部442之間的界面及當光線L行經位置^ 並依序通過第一補償部444和間隔部442之間的界面 時,也會發生光學特性變異的情形。 然而,當第一電極圖案222的折射率與第一補償部 444的折射率相近時,光線L於第一電極圖案222和間隔 部442之間的界面所產生之光學特性變異程度會與光線 201035837 WP9702-C400-0766 28167twf.doc/n L於第一補償部444和間隔部442之間的界面 2學度相去不遠。換句話說,#第―電極圖i 的折射率近似於第一補償部444的折射率時 料 降低上述之一界面處的光學特性差異。 / ❹As shown in FIG. 4, when the light ray passes through the position Α and sequentially passes through the first electrode pattern 222 and the spacer 442, the refraction phenomenon occurring at the interface between the first electrode pattern 222 and the 间隔 spacer 442 changes the light. L Optical characteristics, such as the degree of reflection of light L, the degree of penetration, brightness, and the like. Similarly, when the light ray passes through the position B and sequentially passes through the interface between the first compensation portion 444 and the spacer portion 442 and when the light ray passes through the position ^ and sequentially passes between the first compensation portion 444 and the spacer portion 442 At the time of the interface, the optical characteristics may also vary. However, when the refractive index of the first electrode pattern 222 is close to the refractive index of the first compensation portion 444, the optical characteristic variation degree of the light ray L generated at the interface between the first electrode pattern 222 and the spacer portion 442 may be compared with the light 201035837.

In other words, the refractive index of the #electro-electrode diagram i approximates the refractive index of the first compensating portion 444 to lower the difference in optical characteristics at one of the above interfaces. / ❹
由上述可推得而知,光線L行經第二電極圖宰 和間隔部442之間的界面與第二補償部條和間隔邻 之間的界©也會有光學特性變異關題。因此 用第二電極圖案232的折射率近似於第 U 折射率的方式則可有效降低此二界面的光學的 愈本實施例中,第一電極圖案222的折射率 ”第補W 444的折射率差異至少小於〇 5,且 極圖案232的折射率與第二補償部祕#折射率差^ y小於0.5。如此’光線Lit過第一電極 光線L通過第-補償部蝴,而光線L通過第IS 案232可視為光線L通過第二補償部祕 Ο 線”于經位置A、位置B與位置c之後所 射等光學作用都是錢相同的。如此—來,電式 的光學性質。電容式觸控面板4f〇 二補償部444/446可選用折 的有機ϋ例如折射率實f上介於L55 i 2.5之間 或乳化物等介電材料,較佳地例如折射率實質 11 201035837 w^y/u^-C400-0766 28167twf.doc/n 上介於1.7至2.4之㈣㈣包括二氧化 氧化二鈮(Nb205)、五氧化二麵(‘α 2)、五 然而,折射率實質上介於h55至Τ5=5^介電材料。 舉,在此科H 2·5的介電材料不勝枚 二電 〇As can be appreciated from the above, the boundary between the light ray L passing through the second electrode pattern and the spacer 442 and the boundary between the second compensation portion strip and the spacer edge may also have optical property variation. Therefore, in the embodiment in which the refractive index of the second electrode pattern 232 is approximately equal to the U-th refractive index, the refractive index of the first electrode pattern 222 is adjusted to be the refractive index of the first electrode pattern 222. The difference is at least less than 〇5, and the refractive index difference between the polar pattern 232 and the second compensation portion is less than 0.5. Thus the 'light Lit passes through the first electrode ray L through the first compensation portion, and the light L passes through the first The IS case 232 can be regarded as the light L passing through the second compensating part secret line. The optical effects such as the position A, the position B and the position c are the same. So - come, the optical properties of electricity. The capacitive touch panel 4f 补偿 compensation portion 444/446 may be selected from a folded organic enthalpy such as a dielectric material having a refractive index f between L55 i 2.5 or an emulsion, preferably such as a refractive index substantial 11 201035837 w ^y/u^-C400-0766 28167twf.doc/n Between 1.7 and 2.4 (4) (4) includes dioxane dioxide (Nb205), pentoxide ('α 2), five, however, the refractive index is substantially From h55 to Τ5=5^ dielectric material.

The capacitive touch panel can be ir=near dielectric material and transparent = to = the younger one 乜 444 and the first The electrode pattern 222, the m material and the transparent conductive material are divided into 446 and the second electrode pattern 232. In 1 light ray L in the capacitive touch panel has been properly compensated by the choice of dielectric materials. Therefore, the thickness d2 of the partition 442 does not have to be limited to a specific value in order to prevent the light L from being uneven in length during traveling. In other words, the thickness d 2 of the spacer 442 of the present embodiment does not affect the change of the light and the edge 1 differently. Therefore, the sub-d2 of the spacer 442 of the present embodiment has adjustability. However, when the thickness of the spacer portion 442 is increased, the overall thickness of the electric valley touch panel 400 is also reduced, so that the capacitive touch panel 400 has the advantage of being thinner. County _, the above can be seen, the capacitive touch panel 400 is applied to the touch-type ", page is not beneficial, can improve the brightness uniformity of the touch-type display, also makes 12 201035837 WP9702-C400-0766 28167ίνν £ά〇〇/η The touch display has the advantage of being thinned.
