圖。請參照圖2，觸控面板200a包括基板202以及多個感 測墊210a。在本實施例中，基板202例如是玻璃基板等硬 式透明基板。在其他實施例中，基板202也可以是塑膠透 明基板或其他的可撓式透明基板。感測塾21〇a的材質可以 為透明導電材質’例如：姻錫氧化物、鋼辞氧化物或其他 適當的透明導電材質。 多個感測墊210a配置於基板202上，其中相鄰的兩 個感測墊是平行且相對排列，且各感測墊21〇a包括中間部 分212以及多個凸出部分214a。中間部分21〇a具有多個 側邊215，而多個凸出部分214a由中間部分212的多個側 邊215向外延伸。在觸控面板200a中，每個感測墊21〇& 的中間部分212為菱形或正方形，惟本發明不限於此。在 其他實施例中，每個感測墊21〇a的_間部分212也可以是 其他適當的形狀。 在兩個相鄰的感測墊21〇a中’彼此平行且相對的兩 條側邊215之間的多個凸出部分214a為交錯配置。換言 之，在彼此平行且相對的兩條側邊215之間，由其中一條 側邊215凸出的凸出部分214a會面對另一條侧邊215。 在觸控面板200a中，各感測墊21〇&具有相同數量的 201126231 2009-I-P-D-026TW 32969twf.doc/n 凸出部分214a，且多個凸出部分214a具有相同的形狀， 例如：矩形。多個凸出部分214a凸出於各感測墊210a的 側邊215 ’使得每個感測塾210a的邊緣形成鑛齒狀的圖 案。如此一來，當使用者在觀看觸控面板200a時，使用者 所看到的間隙S會隨著感測墊210a的鋸齒狀邊緣而彎曲， 亦即產生視覺模糊的效果。因此，相較於習知的觸控面板 100 ’使用者比較不會看到觸控面板200a上顯示不均的問 • 題。 由於每個感測墊210a的面積是中間部分212與多個 凸出部分214a的總和’因此本實施例的感測墊2i〇a面積 會大於習知的感測墊面積。如此一來，當使用者觸碰觸控 面板200a時’觸控面板200a上觸碰位置的感測墊21〇a的 電容變化會較為明顯。換言之，相較於習知的觸控面板 1 〇 〇 ’本實施例的觸控面板200a可具有較佳的觸控靈敏度。 在本實施例中’多個凸出部分214a具有相同的形狀 • 與面積，而每個凸出部分214 a與其相對的側邊2丨5之間的 距離s為相同。簡言之，任何相鄰的兩個感測墊21〇a之間 的距離S為相等。在本實施例中，任何兩個相鄰的感測墊 21〇a之間的距離s約為30〜5〇微米。由於觸控面板2〇如 中任何兩個相鄰的感測墊21〇a之間的距離s為相等，因此 觸控面板20〇a上的電容值的分配比較不會受到凸出部分 214a所影響。也就是說，觸控面板2〇〇a上每個感測墊^二 所能形成的電容值相當穩定且均勻。 此外，觸控面板200a上例如還設置有多條用以電連 201126231 2009-I-P-D-026TW 32969twf.doc/n 接感測墊210a的連接線(未繪示），此部分可視需要設計不 同的電連接方式。舉例來說，觸控面板200a可以是一種電 容式觸控面板或電阻式觸控面板。另一方面，觸控面板 200a還可以是單面式或雙面式的觸控面板設計。本領域具

凸出部分214b皆為三角形。此時’相鄰的兩個感測墊2i〇b 之間的距離S，即為相鄰的兩個凸出部分214b的側邊217 之間的距離S。 同樣地’由於每個感測墊210b的邊緣為鋸齒狀，且 彼此平行且相鄰的兩個側邊215之間的多個凸出部分214b 為交錯配置’使得使用者產生視覺模糊的效果，因此觸控 面板200b可有效改善顯示不均的問題。再者，由於任何兩 個相鄰的感測墊21〇b之間的距離S為相同，因此觸控面 板200b上的電容值分配將會均勻而穩定。並且，由於凸出 部分214b可增加感測墊21〇b的面積，因此觸控面板2〇〇b 可具有較佳的觸控靈敏度。 201126231 2009-I-P-D-026TW 32969twf.doc/n 第三實施例 圖4為本發明第三實施例之觸控面板的局部上視示意 圖。請參照圖4，觸控面板200c具有觸控面板2〇〇a的大 部分構件，其中相同的構件以相同的標號表示，以下不再 重述。 觸控面板200c與觸控面板200a的主要不同之處在 於’在觸控面板200c中，配置於基板202上的每個感測塾 210c所包括的多個凸出部分214c皆為梯形。基於相同的 理由，觸控面板200c可達到上述觸控面板2〇〇a或200b 的所有技術功效。 第四實施例 圖5為本發明第四實施例之觸控面板的局部上視示意

2l4d與多個凹入部分216d為交替排列。此外，多個凹入 部分216d例如也皆為圓弧形。然而，此處僅為舉例說明， 本發明並不限制凸出部分或凹入部分的形狀或數量，本領 域具有通常知識者，當可視需要加以變化。 、 上述的觸控面板200a、2〇〇b、200c、200d中的感測 201126231 2009-I-P-D-026TW 32969twf.doc/n 墊210a、210b、210c、21〇d均設置有多個凸出部分214a、 214b、214c、214d ’ 使得感測墊 21〇a、21〇b、210c、2i〇d 邊緣為鑛齒狀而產生視覺模糊的效果，進而改善顯示不均 的問題。並且’任兩相鄰的感測墊21〇a、21〇b、21〇c、21〇d 之間的距離S為相等，因此觸控面板200a、200b、200c、 200d可具有良好的電容值分配。再者’由於凸出部分 214a、214b、214c、214d 分別增加了 感測墊 210a、210b、 210c、210d 的面積’因此觸控面板 2〇〇a、2〇〇b、2〇〇c、2〇〇d 可具有較佳的觸控靈敏度。另外，值得一提的是，本發明 的觸控面板相當容易製作’僅需稍微改變感測墊的光罩設 計即可製作上述的觸控面板2〇〇a、200b、200c、200d，並 不需要改變原本的製作方式。 為清楚說明本發明所達到視覺模糊的效果，以下特將 習知的觸控面板與本發明之觸控面板並列以便理解。 圖6A為圖1所繪·示之觸控面板的局部上視示意圖， 其中圖6A較圖1涵蓋較多的感測墊。圖6B為圖4所繪示 之觸控面板的局部上視示意圖，其中圖6B較圖4涵蓋較 夕的感測墊。由圖6A與圖6B可知，相較於習知的觸控面 板100，本發明的觸控面板2〇〇c可以產生視覺模糊的效 果，從而改善顯示不均的問題。

觸控顯示裝置300可具有良好的顯示均勻性以及觸控靈敏 度。換言之’觸控顯示裝置300可具有良好的顯示效果以 及操控性。 綜上所述，本發明的觸控面板的感測墊設置有交錯配 置的多個凸出部分，使得感測墊的邊緣為鋸齒狀而產生視 覺模糊。換言之，使用者比較不會看到顯示不均的現象。 再者，由於任何兩個觸控墊之間的距離為相等，因此本發 明的觸控面板上的電容值相當平均而穩定。再者，由於^

Description of the Invention: [Technical Field] The present invention relates to a touch panel, and in particular to a display uniformity and touch Sensitive touch panel. [Prior Art] Most of the conventional touch display modules integrate the touch panel with the display panel. Touch panels can be roughly classified into resistive, capacitive, infrared, and ultrasonic touch panels. Among them, resistive touch panels and capacitive touch panels are the most common products. Since the touch display module can provide a more user-friendly operation mode, it is gradually favored by the market. FIG. 1 is a partial top view of a conventional touch panel. Referring to FIG. 1 , the touch panel 100 includes a substrate 102 and a plurality of sensing pads 110 . A plurality of sensing pads 110 are disposed on the substrate 102 and spaced apart from each other by a gap s. In addition, the touch panel 100 further includes a plurality of connecting lines (not shown) for connecting the plurality of sensing pads 11' to transmit signals to the respective sensing pads 110. For example, when the user touches the touch panel 100 with a finger, at the position touched by the user, part of the sensing pad 110 forms a capacitance with the finger, thereby causing a change in the signal. However, since the light transmittance of the sensing pad 110 and the substrate 100 is the same, the linear gap s between the plurality of sensing pads 110 causes the touch panel 100 to exhibit a display unevenness (Mura). In other words, when the user views the touch display device using the touch panel 100, the quality of the display is poor. 201126231 2009-IPD-026TW 32969twf.d〇c/n In this regard, Chinese Patent Application No. CN101131492 proposes a method for improving the uniformity of display of a touch panel, which mainly sets a pseudo between two adjacent sensing pads. pattern. In addition, Chinese Patent Application No. CN101126969 has a variety of electric valley touch panels with a polygonal sensing design. However, Chinese Patent Application No. CN101131492 requires a high process precision, and Chinese Patent Application No. CN101126969 does not effectively solve the above problem of display unevenness. From this, it can be seen that 'how to improve the display uniformity of the touch panel 1 , is really a problem to be solved. SUMMARY OF THE INVENTION The present invention provides a touch panel having good display and touch sensitivity. The invention provides a touch panel comprising a substrate and a plurality of sensing electrodes. A plurality of sensing pads are disposed on the substrate, wherein the adjacent two senses a are parallel and oppositely arranged, and each of the sensing pads includes an intermediate portion and a plurality of convex portions. The intermediate portion has a plurality of sides, and the plurality of projections extend outwardly from the plurality of sides of the intermediate portion. The plurality of projections between the two adjacent sensing pads are in a staggered configuration. The distance between any two adjacent == pads is equal. In an embodiment of the invention, the shape of the plurality of protruding portions is the same as 0. In an embodiment of the invention, each of the sensing pads further includes a plurality of ingress portions. The plurality of concave portions are inwardly defined by the plurality of sides of the intermediate portion = recessed 201126231 2009-IPD-026TW 32969twf.doc/n and the plurality of convex portions and the plurality of concave portions are alternately arranged . Similarly, the shapes of the plurality of concave portions are the same. The throwing of the convex portions In one embodiment of the present invention, a diamond or a square. The middle portion of each of the upper 4 sensing pads is in the embodiment of the present invention, and includes any two phases of the plurality of embossed pads including the rectangular, triangular, and trapezoidal sensing ridges. In the embodiment of the neighboring senses, in the embodiment in which the plurality of convex portions of the sensing electrodes are transparent, the material of the plurality of sensing electrodes is -2. The transparent conductive material includes indium tin oxide or indium zinc oxide. The sensing layer of the touch panel of the present invention described above is provided with a plurality of protrusions A. The file ' makes the edge of the touch pad be paved and the plurality of protrusions are configured. In this way, the latter will be able to produce a visual paste when it is used to control the panel, and it will not look like a coffee. The distance between any two touches is equal, so the capacitance value of the touch panel of the present invention is more than: average. Moreover, since the protruding portion increases the area of the touch pad, the touch panel of the t-light can have good touch sensitivity. In addition, in the present invention, the touch display device has the touch panel described above, and thus has a good display effect. In order to make the above features and advantages of the present invention more comprehensible, the following embodiments are described in detail below with reference to the accompanying drawings. [Embodiment] FIG. 2 is a partial top plan view of a touch panel according to a first embodiment of the present invention. Referring to FIG. 2, the touch panel 200a includes a substrate 202 and a plurality of sensing pads 210a. In the present embodiment, the substrate 202 is, for example, a hard transparent substrate such as a glass substrate. In other embodiments, the substrate 202 can also be a plastic transparent substrate or other flexible transparent substrate. The material of the sensing 塾21〇a may be a transparent conductive material such as: a tin oxide, a steel oxide or other suitable transparent conductive material. The plurality of sensing pads 210a are disposed on the substrate 202, wherein the adjacent two sensing pads are parallel and oppositely arranged, and each of the sensing pads 21A includes an intermediate portion 212 and a plurality of protruding portions 214a. The intermediate portion 21a has a plurality of sides 215, and the plurality of raised portions 214a extend outwardly from the plurality of sides 215 of the intermediate portion 212. In the touch panel 200a, the intermediate portion 212 of each of the sensing pads 21A & is a diamond or a square, but the invention is not limited thereto. In other embodiments, the inter-portion portion 212 of each of the sensing pads 21a may also be of other suitable shapes. The plurality of convex portions 214a between the two adjacent sensing pads 21A' which are parallel to each other and opposite to each other are in a staggered configuration. In other words, between the two side edges 215 which are parallel and opposite each other, the convex portion 214a projecting from one of the side edges 215 faces the other side edge 215. In the touch panel 200a, each of the sensing pads 21A & has the same number of 201126231 2009-IPD-026TW 32969twf.doc/n convex portions 214a, and the plurality of convex portions 214a have the same shape, for example, a rectangle . A plurality of projections 214a project from the side edges 215' of each of the sensing pads 210a such that the edges of each of the sensing jaws 210a form a pattern of mineral teeth. As a result, when the user views the touch panel 200a, the gap S seen by the user is curved along with the jagged edge of the sensing pad 210a, that is, the effect of visual blurring is generated. Therefore, compared with the conventional touch panel 100' user, the problem of uneven display on the touch panel 200a is not seen. Since the area of each of the sensing pads 210a is the sum of the intermediate portion 212 and the plurality of protruding portions 214a, the sensing pad 2i〇a area of the present embodiment may be larger than the conventional sensing pad area. As a result, when the user touches the touch panel 200a, the capacitance change of the sensing pad 21〇a at the touch position on the touch panel 200a is more obvious. In other words, the touch panel 200a of the present embodiment can have better touch sensitivity than the conventional touch panel 1 〇 。. In the present embodiment, the plurality of convex portions 214a have the same shape and area, and the distance s between each of the convex portions 214a and the opposite side edges 2丨5 is the same. In short, the distance S between any two adjacent sensing pads 21a is equal. In this embodiment, the distance s between any two adjacent sensing pads 21a is about 30 to 5 microns. Since the distance s between any two adjacent sensing pads 21a of the touch panel 2 is equal, the distribution of the capacitance values on the touch panel 20A is not compared by the protruding portion 214a. influences. That is to say, the capacitance value that each of the sensing pads 2 on the touch panel 2A can form is relatively stable and uniform. In addition, the touch panel 200a is further provided with a plurality of connecting lines (not shown) for electrically connecting the 201126231 2009-IPD-026TW 32969twf.doc/n to the sensing pad 210a, and the part can be designed with different electric power as needed. Connection method. For example, the touch panel 200a can be a capacitive touch panel or a resistive touch panel. On the other hand, the touch panel 200a can also be a single-sided or double-sided touch panel design. Those skilled in the art will understand the operation principle of the touch panel 200a and other component configurations, and will not be described herein. Second Embodiment FIG. 3 is a partial top plan view of a touch panel according to a second embodiment of the present invention. Referring to FIG. 3, the touch panel 200b has a majority of the components of the touch panel 200a, wherein the same components are denoted by the same reference numerals and will not be described again. The main difference between the touch panel 200b and the touch panel 200a is that in the touch panel 200b, each of the plurality of convex portions 214b included in each of the sensing electrodes 210b is triangular. At this time, the distance S between the adjacent two sensing pads 2i, b is the distance S between the side edges 217 of the adjacent two convex portions 214b. Similarly, 'because the edges of each of the sensing pads 210b are jagged, and the plurality of protruding portions 214b between the two side edges 215 that are parallel to each other and adjacent to each other are in a staggered configuration', the user produces a visual blur effect. Therefore, the touch panel 200b can effectively improve the problem of display unevenness. Moreover, since the distance S between any two adjacent sensing pads 21〇b is the same, the capacitance value distribution on the touch panel 200b will be uniform and stable. Moreover, since the protruding portion 214b can increase the area of the sensing pad 21b, the touch panel 2b can have better touch sensitivity. 201126231 2009-I-P-D-026TW 32969twf.doc/n Third Embodiment FIG. 4 is a partial top plan view of a touch panel according to a third embodiment of the present invention. Referring to FIG. 4, the touch panel 200c has a majority of the components of the touch panel 2A, wherein the same components are denoted by the same reference numerals and will not be described again. The main difference between the touch panel 200c and the touch panel 200a is that in the touch panel 200c, the plurality of protruding portions 214c included in each of the sensing electrodes 210c disposed on the substrate 202 are trapezoidal. For the same reason, the touch panel 200c can achieve all the technical effects of the above touch panel 2a or 200b. Fourth Embodiment Fig. 5 is a partial top plan view showing a touch panel according to a fourth embodiment of the present invention. Referring to FIG. 5, the touch panel 200d has a majority of the members of the touch panel 2A, wherein the same components are denoted by the same reference numerals and will not be repeated below. The plurality of sensing jaws 210d of the touch panel 200d respectively have a plurality of arcuate projections 214d. In particular, each of the sensing pads 21〇d further includes a plurality of recessed portions 216d. The plurality of concave portions 216d are recessed inwardly by the plurality of side edges 215 of the intermediate portion 212, and the plurality of convex portions 214d of the respective sensing pads 2i 〇d and the plurality of concave portions 216d are alternately arranged. Further, the plurality of concave portions 216d are, for example, also circular arc shapes. However, the description herein is merely illustrative, and the present invention does not limit the shape or number of the convex portions or the concave portions, and those skilled in the art will be able to vary as needed. The sensing 201126231 2009-IPD-026TW 32969twf.doc/n pads 210a, 210b, 210c, 21〇d in the above touch panels 200a, 2〇〇b, 200c, 200d are each provided with a plurality of protruding portions 214a 214b, 214c, and 214d' cause the edges of the sensing pads 21〇a, 21〇b, 210c, and 2i〇d to be mineral-toothed, thereby producing a visual blurring effect, thereby improving the problem of display unevenness. And the distance S between any two adjacent sensing pads 21〇a, 21〇b, 21〇c, 21〇d is equal, so the touch panels 200a, 200b, 200c, 200d can have good capacitance values. distribution. Furthermore, since the convex portions 214a, 214b, 214c, and 214d respectively increase the area of the sensing pads 210a, 210b, 210c, 210d, the touch panels 2〇〇a, 2〇〇b, 2〇〇c, 2 〇〇d can have better touch sensitivity. In addition, it is worth mentioning that the touch panel of the present invention is relatively easy to manufacture. The touch panel 2a, 200b, 200c, and 200d can be fabricated by simply changing the mask design of the sensing pad. Need to change the original production method. In order to clearly illustrate the effect of the visual blur achieved by the present invention, the conventional touch panel will be juxtaposed with the touch panel of the present invention for understanding. FIG. 6A is a partial top plan view of the touch panel illustrated in FIG. 1 , wherein FIG. 6A covers more sensing pads than FIG. 1 . FIG. 6B is a partial top view of the touch panel illustrated in FIG. 4, wherein FIG. 6B compares the sensing pads of FIG. 4 with respect to FIG. As can be seen from FIGS. 6A and 6B, the touch panel 2〇〇c of the present invention can produce a visual blur effect compared to the conventional touch panel 100, thereby improving the problem of display unevenness. Fig. 7 is a schematic view of a touch display device using the touch panel of the present invention. Referring to FIG. 7, the touch display device 30 includes a display panel 31 and a touch panel 320. The touch panel 32 is disposed on the display panel 31A. In the touch display device 3 of the present embodiment, the display panel 31 is exemplified by a liquid crystal display panel, a plasma display panel, or an organic electroluminescence display panel. For example, when the display panel 310 is a liquid crystal display panel, the liquid crystal display panel includes a transmissive liquid crystal display panel, a reflective liquid crystal display panel, a transflective liquid crystal display panel, and other forms of liquid crystal display panels. In the embodiment illustrated in FIG. 7, the touch panel 320 is, for example, any one of the touch panels 200a, 200b, 200c, or 200d in the above embodiment. Since the touch panel 200a, 200b, 200c or 200d can achieve the above-mentioned visual blurring effect and has a large sensing pad area, the touch display device 300 can have good display uniformity and touch sensitivity. In other words, the touch display device 300 can have a good display effect and maneuverability. In summary, the sensing pad of the touch panel of the present invention is provided with a plurality of embossed portions which are staggered so that the edges of the sensing pads are jagged and cause visual blur. In other words, the user does not see the phenomenon of uneven display. Moreover, since the distance between any two touch pads is equal, the capacitance values on the touch panel of the present invention are relatively average and stable. Moreover, since the sensing portion can increase the sensing pad area, the touch panel of the present invention can have better touch sensitivity. Further, the touch panel of the present invention is relatively easy to manufacture and hardly causes an increase in manufacturing cost. The touch display device of the present invention has the touch panel described above, and thus can have a good display effect.
