請同時參照圖2以及圖3，本實施例之電容式觸控面板500包括一第一基板510、多個第一電極圖案520、多個第二電極圖案530以及多個擬電極圖案540，其中第一電極圖案520、第二電極圖案530以及擬電極圖案540例如是共平面地位於第一基板510上。Referring to FIG. 2 and FIG. 3 , the capacitive touch panel 500 of the present embodiment includes a first substrate 510 , a plurality of first electrode patterns 520 , a plurality of second electrode patterns 530 , and a plurality of pseudo electrode patterns 540 . The first electrode pattern 520, the second electrode pattern 530, and the pseudo electrode pattern 540 are, for example, coplanar on the first substrate 510.
此外，第一電極圖案520、第二電極圖案530以及擬電極圖案540為相同材質，例如銦錫氧化物(Indium Tin Oxides,ITO)、銦鋅氧化物(Indium Zinc Oxide,IZO)等透明導電材質；而第一基板510可為透明玻璃、彩色濾片或鏡片(Lens)其中之一。In addition, the first electrode pattern 520, the second electrode pattern 530, and the pseudo electrode pattern 540 are made of the same material, such as indium tin oxide (ITO), indium zinc oxide (Indium Zinc Oxide, IZO), etc. And the first substrate 510 may be one of a transparent glass, a color filter or a lens (Lens).
在實際產品的應用上，於第一基板510上形成第一電極圖案520、第二電極圖案530以及擬電極圖案540之後，可進一步形成一保護層550以覆蓋並保護第一、第二電極圖案520、530與擬電極圖案540，其中保護層550的材質可選用不會導電的介電材料。After the first electrode pattern 520, the second electrode pattern 530, and the pseudo electrode pattern 540 are formed on the first substrate 510, a protective layer 550 may be further formed to cover and protect the first and second electrode patterns. 520, 530 and a pseudo electrode pattern 540, wherein the material of the protective layer 550 is selected from a dielectric material that does not conduct electricity.
在本實施例中，第一電極圖案520串接成多個感測串列，而第二電極圖案530串接成另外多個感測串列，且第一電極圖案520所串接成的感測串列與第二電極圖案530所串接成的感測串列相交，詳言之，第一電極圖案520是沿著第一方向X串接成多個第一感測串列520S，而第二電極圖案530是沿著第二方向Y串接成多個第二感測串列530S，且第一方向X以及第二方向Y彼此相交。In this embodiment, the first electrode patterns 520 are serially connected into a plurality of sensing series, and the second electrode patterns 530 are serially connected into another plurality of sensing series, and the first electrode patterns 520 are connected in series. The measurement series intersects the sensing series connected in series with the second electrode pattern 530. In detail, the first electrode pattern 520 is serially connected in the first direction X into a plurality of first sensing series 520S, and The second electrode pattern 530 is serially connected in the second direction Y into a plurality of second sensing series 530S, and the first direction X and the second direction Y intersect each other.
實務上，電容式觸控面板500中設置多條第一連接線520a以及多條第二連接線530a，以形成上述之第一、第二感測串列520S、530S。如圖2所示，沿著第一方向X的同一列第一感測串列520S中兩相鄰的第一電極圖案520可透過第一連接線路520a的設置而彼此電性連接，進而串接成一條第一感測串列520S；同樣地，沿著第二方向Y的同一行第二感測串列530S中兩相鄰的第二電極圖案530可透過第二連接線530a的設置而彼此電性連接，進而串接成一條第二感測串列530S。In practice, the capacitive touch panel 500 is provided with a plurality of first connecting lines 520a and a plurality of second connecting lines 530a to form the first and second sensing series 520S, 530S. As shown in FIG. 2, two adjacent first electrode patterns 520 in the same row of the first sensing series 520S in the first direction X can be electrically connected to each other through the arrangement of the first connecting lines 520a, and then connected in series A first sensing series 520S is formed; likewise, two adjacent second electrode patterns 530 of the second sensing series 530S in the same row along the second direction Y are transparent to each other through the arrangement of the second connecting lines 530a Electrically connected, and then connected in series to a second sensing series 530S.
在此需要說明的是，第一連接線520a以及第二連接線530a彼此絕緣以使電容式觸控面板500可以正常地運作，此外，第一連接線520a以及第二連接線530a的線路佈局會視實際產品而有所不同，且圖2中所繪示的第一連接線520a以及第二連接線530a僅用來方便說明本實施例，並非表示第一連接線520a以及第二連接線530a的實際線路佈局，且第一連接線520a以及第二連接線530a可為銦錫氧化物(Indium Tin Oxides,ITO)、銦鋅氧化物(Indium Zinc Oxide,IZO)等透明導電材質或金屬材質。It should be noted that the first connection line 520a and the second connection line 530a are insulated from each other to enable the capacitive touch panel 500 to operate normally. In addition, the line layout of the first connection line 520a and the second connection line 530a may be The first connection line 520a and the second connection line 530a are only used to facilitate the description of the present embodiment, and are not representative of the first connection line 520a and the second connection line 530a. The actual line layout, and the first connection line 520a and the second connection line 530a may be transparent conductive materials such as indium tin oxide (ITO), indium zinc oxide (Indium Zinc Oxide, IZO), or a metal material.
為了使第一感測串列520S以及第二感測串列530S與外部電路連結(銲墊、打線、連結器等)，通常會在第一基板510上設置多條第一導電線路522以及多條第二導電線路532，且第一導電線路522分別電性連接對應的第一感測串列520S，以傳送對應的第一感測串列520S的電壓訊號，而第二導電線路532分別電性連接對應的第二感測串列530S，以傳送對應的第二感測串列530S的電壓訊號。In order to connect the first sensing series 520S and the second sensing series 530S to external circuits (pads, wires, connectors, etc.), a plurality of first conductive lines 522 and a plurality of first conductive lines 522 are usually disposed on the first substrate 510. The second conductive line 532 is electrically connected to the corresponding first sensing series 520S to transmit the voltage signal of the corresponding first sensing series 520S, and the second conductive line 532 is respectively charged. The second sensing series 530S corresponding to the connection is connected to transmit the voltage signal of the corresponding second sensing series 530S.
在本實施例中，第二電極圖案530與第一電極圖案520彼此分離，其中每一第一電極圖案520與相鄰的其中一第二電極圖案530在平行於第一基板510的一水平方向相隔一間隙G；如此，當第一電極圖案520以及第二電極圖案530分別被施以適當的電壓時，第一電極圖案520以及第二電極圖案530之間便可產生電容效應，例如間隙G的寬度約為100微米(micrometer,um)，當然，實際寬度應隨著產品的需求作適度地調整，本發明並不限制。In this embodiment, the second electrode pattern 530 and the first electrode pattern 520 are separated from each other, wherein each of the first electrode patterns 520 and one of the adjacent second electrode patterns 530 are in a horizontal direction parallel to the first substrate 510. A gap G is separated from each other. When the first electrode pattern 520 and the second electrode pattern 530 are respectively applied with appropriate voltages, a capacitive effect, such as a gap G, can be generated between the first electrode pattern 520 and the second electrode pattern 530. The width is about 100 micrometers (um). Of course, the actual width should be adjusted appropriately according to the requirements of the product, and the invention is not limited.
在本實施例中，擬電極圖案540位在間隙G內，並與第一電極圖案520以及第二電極圖案530電性絕緣，其中圖2中每一擬電極圖案540及其相鄰的第一、第二電極圖案520、530相隔一距離d，例如距離d可以介於10微米至30微米之間，但實際距離應視產品需求或製程能力而作適度地調整，本發明並不限制。In this embodiment, the pseudo electrode pattern 540 is located in the gap G and electrically insulated from the first electrode pattern 520 and the second electrode pattern 530, wherein each of the pseudo electrode patterns 540 and its adjacent first in FIG. The second electrode patterns 520 and 530 are separated by a distance d. For example, the distance d may be between 10 micrometers and 30 micrometers. However, the actual distance should be appropriately adjusted according to product requirements or process capability, and the present invention is not limited thereto.
另外，如圖2所示，本實施例之擬電極圖案540為條狀，其中每一擬電極圖案540鄰近於一個第一電極圖案520以及一個第二電極圖案530。其他實施例中，如圖2A所示，至少部分的擬電極圖案540還可進一步彼此相連，以形成多個交叉狀的電極圖案。In addition, as shown in FIG. 2, the pseudo electrode patterns 540 of the present embodiment are strip-shaped, wherein each of the pseudo electrode patterns 540 is adjacent to one first electrode pattern 520 and one second electrode pattern 530. In other embodiments, as shown in FIG. 2A, at least portions of the pseudo electrode patterns 540 may be further connected to each other to form a plurality of intersecting electrode patterns.
由圖3可知，當光線L自第一基板510下方入射時，行經位置H的光線L會依序通過第一基板510以及第一電極圖案520，而行經位置I的光線L會依序通過第一基板510以及第二電極圖案530，且行經位置J的光線L會依序通過第一基板510以及擬電極圖案540。由於第一電極圖案520、第二電極圖案530以及擬電極圖案540三種電極圖案的材質相同而具有相同的折射率，因而光線L通過電容式觸控面板500a之後在位置H、位置I及位置J所受到的折射、反射等光學作用實質上相等。As can be seen from FIG. 3, when the light L is incident from below the first substrate 510, the light L passing through the position H passes through the first substrate 510 and the first electrode pattern 520 in sequence, and the light L passing through the position I passes through the first step. A substrate 510 and a second electrode pattern 530, and the light L passing through the position J passes through the first substrate 510 and the pseudo electrode pattern 540 in sequence. Since the three electrode patterns of the first electrode pattern 520, the second electrode pattern 530, and the pseudo electrode pattern 540 have the same refractive index, the light L passes through the capacitive touch panel 500a at the position H, the position I, and the position J. The optical effects such as refraction and reflection are substantially equal.
本實施例之擬電極圖案540雖與第一電極圖案520或第二電極圖案530相隔有距離d，但距離d的寬度很小，而使人眼無法察覺出來，所以，電容式觸控面板500a在各個位置呈現相當均勻的光線穿透度。The pseudo electrode pattern 540 of the present embodiment is separated from the first electrode pattern 520 or the second electrode pattern 530 by a distance d, but the width of the distance d is small, so that the human eye cannot detect it. Therefore, the capacitive touch panel 500a A fairly uniform light penetration at each location.
同時，擬電極圖案540為浮置的導體圖案，所以第一電極圖案520與第二電極圖案530之間的電容效應不會受到影響，換言之，擬電極圖案540在不影響電容式觸控面板500a的觸控功能下，提升電容式觸控面板500a的光學效果，且擬電極圖案540與第一、第二電極圖案520、530在同一個製程步驟中製作，所以擬電極圖案540不會增加電容式觸控面板500a的製程負擔。At the same time, the pseudo electrode pattern 540 is a floating conductor pattern, so the capacitive effect between the first electrode pattern 520 and the second electrode pattern 530 is not affected. In other words, the pseudo electrode pattern 540 does not affect the capacitive touch panel 500a. Under the touch function, the optical effect of the capacitive touch panel 500a is improved, and the pseudo electrode pattern 540 is fabricated in the same process step as the first and second electrode patterns 520, 530, so the pseudo electrode pattern 540 does not increase the capacitance. The process burden of the touch panel 500a.
根據圖2中沿L1-L1’剖面線，電容式觸控面板的設計還可以為圖4～圖6所繪示的樣貌。本實施例欲闡述的精神與第一實施例相類似，而本實施例與第一實施例二者主要差異在於：本實施例之電容式觸控面板500b、500c、500d中的第一電極圖案520以及第二電極圖案530的設置為非共平面。According to the L1-L1' section line in Fig. 2, the design of the capacitive touch panel can also be as shown in Figs. 4-6. The spirit of the present embodiment is similar to that of the first embodiment, and the main difference between the present embodiment and the first embodiment is that the first electrode pattern in the capacitive touch panel 500b, 500c, 500d of the present embodiment The arrangement of 520 and the second electrode pattern 530 is non-coplanar.
請先參照圖4，本實施例之電容式觸控面板500b進一步設置第二基板610以及一介電層640，介電層640配置於第一基板510以及第二基板610之間，第一電極圖案520以及擬電極圖案540配置於介電層640與第一基板510之間，且第二電極圖案530配置於介電層640與第二基板610之間，也就是說，第一電極圖案520與第二電極圖案530分別地配置於介電層640的兩側。其中第一基板510或第二基板610可為透明玻璃、彩色濾片或鏡片(Lens)其中之一。Referring to FIG. 4, the capacitive touch panel 500b of the present embodiment further includes a second substrate 610 and a dielectric layer 640. The dielectric layer 640 is disposed between the first substrate 510 and the second substrate 610. The pattern 520 and the dummy electrode pattern 540 are disposed between the dielectric layer 640 and the first substrate 510 , and the second electrode pattern 530 is disposed between the dielectric layer 640 and the second substrate 610 , that is, the first electrode pattern 520 . The second electrode patterns 530 are disposed on both sides of the dielectric layer 640, respectively. The first substrate 510 or the second substrate 610 may be one of a transparent glass, a color filter or a lens (Lens).
由圖4可知，當光線L自第一基板510下方入射並射出第二基板610時，行經位置K的光線L通過第一電極圖案520以及介電層640，而行經位置M的光線L通過介電層640以及第二電極圖案530，且行經位置N的光線L通過擬電極圖案540以及介電層640，且由於第一電極圖案520、第二電極圖案530以及擬電極圖案540三種電極圖案的材質相同，而具有相同的折射率，因而光線L通過電容式觸控面板500b之後，在各位置所受到的折射、反射等光學作用實質上相等，如此電容式觸控面板600b可以提供均勻的光穿透性質。As can be seen from FIG. 4, when the light L is incident from the lower surface of the first substrate 510 and exits the second substrate 610, the light L passing through the position K passes through the first electrode pattern 520 and the dielectric layer 640, and the light L passing through the position M passes through The electric layer 640 and the second electrode pattern 530, and the light L passing through the position N passes through the pseudo electrode pattern 540 and the dielectric layer 640, and due to the three electrode patterns of the first electrode pattern 520, the second electrode pattern 530, and the pseudo electrode pattern 540 The materials are the same and have the same refractive index. Therefore, after the light L passes through the capacitive touch panel 500b, the optical effects of refraction and reflection at each position are substantially equal, so that the capacitive touch panel 600b can provide uniform light. Penetrating properties.
當然，本實施例不限於此，如圖5所繪示的電容式觸控面板500c中，擬電極圖案540配置於第二基板610與介電層640之間。另外，圖6所繪示的電容式觸控面板500d中，部分的擬電極圖案540配置於第二基板610與介電層640之間，而另一部分的擬電極圖案540則配置於第一基板510與介電層640之間。Of course, the embodiment is not limited to this. In the capacitive touch panel 500c illustrated in FIG. 5 , the pseudo electrode pattern 540 is disposed between the second substrate 610 and the dielectric layer 640 . In addition, in the capacitive touch panel 500d illustrated in FIG. 6 , a portion of the pseudo electrode pattern 540 is disposed between the second substrate 610 and the dielectric layer 640 , and another portion of the pseudo electrode pattern 540 is disposed on the first substrate. Between 510 and dielectric layer 640.
雖然本發明已以較佳實施例揭露如上，然其並非用以限定本發明，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內，當可作些許之更動與潤飾，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。Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention.
