隨著智慧型手機等智慧型產品的發展,顯示器搭配觸控面板已漸漸成為主流。為了使使用者可以在智慧型產品上同時觀查資訊並進行觸碰感應,現今的觸控面板除了本身具有之觸控感測功能之外,還需要具有高穿透率的特性。With the development of smart products such as smart phones, monitors with touch panels have gradually become mainstream.

參照第1圖,第1圖為根據本創作之一實施方式之觸控面板100之示意圖。觸控面板100包含多個第一電極串110、多個第二電極串120以及多個絕緣塊130。第一電極串110沿第一方向D1延伸。第二電極串120沿第二方向D2延伸。絕緣塊130分別設置於第一電極串110與第二電極串120之多個交會處,且每一絕緣塊130設置於第一電極串110之一與第二電極串120之一之間,用以將第一電極串110之一與第二電極 串120之一隔絕開來,其中絕緣塊130分別具有長軸方向LD,至少二個絕緣塊130之長軸方向LD不同。Referring to FIG. 1 , FIG. 1 is a schematic diagram of a touch panel 100 according to an embodiment of the present invention. The touch panel 100 includes a plurality of first electrode strings 110 , a plurality of second electrode strings 120 , and a plurality of insulating blocks 130 . The first electrode string 110 extends in the first direction D1. The second electrode string 120 extends in the second direction D2. The insulating blocks 130 are respectively disposed at a plurality of intersections of the first electrode string 110 and the second electrode string 120, and each insulating block 130 is disposed between one of the first electrode strings 110 and one of the second electrode strings 120. One of the first electrode string 110 and the second electrode One of the strings 120 is isolated, wherein the insulating blocks 130 respectively have a long axis direction LD, and at least two insulating blocks 130 have different major axis directions LD.
於本創作之一或多個實施方式中,於第一方向D1 上的至少二個絕緣塊130之長軸方向LD不同,且於第二方向D2上的至少二個絕緣塊130之長軸方向LD不同。In one or more embodiments of the present creation, in the first direction D1 The at least two insulating blocks 130 have different longitudinal directions LD, and the long axis directions LD of at least two insulating blocks 130 in the second direction D2 are different.
舉例而言,絕緣塊130a、絕緣塊130b、絕緣塊 130c分別具有長軸方向LDa、長軸方向LDb與長軸方向LDc,其中長軸方向LDa與長軸方向LDb並不互相平行,且長軸方向LDa與長軸方向LDc並不互相平行。For example, the insulating block 130a, the insulating block 130b, and the insulating block Each of the 130c has a long axis direction LDa, a long axis direction LDb, and a long axis direction LDc, wherein the long axis direction LDa and the long axis direction LDb are not parallel to each other, and the long axis direction LDa and the long axis direction LDc are not parallel to each other.
多個第一電極串110沿第一方向D1延伸並在第二 方向D2上相互間隔排列,每一第一電極串110包含多個感應電極112與多個連接線114,每一連接線114連接第一方向D1上相鄰的感應電極112。多個第二電極串120沿第二方向D2延伸並在第一方向D1上相互間隔排列,每一第二電極串120包含多個感應電極122與多個連接線124,每一連接線124跨過每一絕緣塊130以連接第二方向D2上相鄰的感應電極122。於本實施方式中,連接線114、連接線124不受絕緣塊130的長軸方向LD影響,每一第一電極串110之連接線114沿第一方向D1延伸和排列,相鄰第一電極串110之連接線114沿第二方向D2間隔排列;每一第二電極串120之連接線124皆沿第二方向D2延伸和排列,相鄰第二電極串120之連接線124沿第一方向D1間隔排列。The plurality of first electrode strings 110 extend in the first direction D1 and are in the second The direction D2 is spaced apart from each other. Each of the first electrode strings 110 includes a plurality of sensing electrodes 112 and a plurality of connecting lines 114. Each of the connecting lines 114 is connected to the adjacent sensing electrodes 112 in the first direction D1. The plurality of second electrode strings 120 extend along the second direction D2 and are spaced apart from each other in the first direction D1. Each of the second electrode strings 120 includes a plurality of sensing electrodes 122 and a plurality of connecting lines 124, and each connecting line 124 spans Each of the insulating blocks 130 passes through the adjacent sensing electrodes 122 in the second direction D2. In the present embodiment, the connecting line 114 and the connecting line 124 are not affected by the long-axis direction LD of the insulating block 130. The connecting line 114 of each first electrode string 110 extends and is arranged along the first direction D1, adjacent to the first electrode. The connecting lines 114 of the string 110 are arranged at intervals along the second direction D2; the connecting lines 124 of each of the second electrode strings 120 are extended and arranged along the second direction D2, and the connecting lines 124 of the adjacent second electrode strings 120 are along the first direction. D1 is arranged at intervals.
如圖中所見,絕緣塊130的寬度可以設計為大於連接線114、連接線124的寬度,但這不應用以限制本創作之 範圍。於某些實施方式中,絕緣塊130的寬度可以設計為等於或小於連接線114寬度。As seen in the figure, the width of the insulating block 130 can be designed to be larger than the width of the connecting line 114 and the connecting line 124, but this is not applied to limit the creation of the present invention. range. In some embodiments, the width of the insulating block 130 can be designed to be equal to or less than the width of the connecting line 114.
於此,在絕緣塊130的配置上,較佳的配置方法 是使絕緣塊130能覆蓋第一電極串110與第二電極串120的交會處。本實施方式中,絕緣塊130位於第一電極串110之連接線114與第二電極串120之連接線124之間。絕緣塊130的長軸方向LD與第二方向D2之間具有夾角A。Here, a preferred configuration method for the arrangement of the insulating block 130 The insulating block 130 is capable of covering the intersection of the first electrode string 110 and the second electrode string 120. In the present embodiment, the insulating block 130 is located between the connecting line 114 of the first electrode string 110 and the connecting line 124 of the second electrode string 120. The longitudinal direction LD of the insulating block 130 has an angle A with the second direction D2.
於某些實施方式中,舉例而言,當絕緣塊130的 寬度的平方值小於連接線114、連接線124的寬度的平方和時,絕緣塊130受夾角A的大小而影響其覆蓋交會處的能力。 詳細而言,當夾角A愈大時,絕緣塊130於第二方向D2的投影愈短,而使得第一電極串110的連接線114愈不容易被絕緣塊130所遮蔽,或者愈不容易隔開連接線114、連接線124。以下提供多種方法用以解決此不易遮蔽的問題。In some embodiments, for example, when insulating block 130 When the square of the width is smaller than the sum of the squares of the widths of the connecting lines 114 and the connecting lines 124, the insulating block 130 is affected by the angle A to affect its ability to cover the intersection. In detail, the larger the angle A is, the shorter the projection of the insulating block 130 in the second direction D2 is, so that the connection line 114 of the first electrode string 110 is less likely to be shielded by the insulating block 130, or the easier it is to separate. The connection line 114 and the connection line 124 are opened. Various methods are provided below to solve this problem that is not easily obscured.
首先,可以配置絕緣塊130的長度隨著絕緣塊130 與第二方向D2的夾角A改變。雖然並未將絕緣塊130的長度明確繪示出來,但需了解到,於本創作之一或多個實施方式中,絕緣塊130於第二方向D2的投影長度可配置大於第一電極串110之連接線114的寬度,使絕緣塊130可至少包覆部份連接線114,以達到隔離第一電極串110與第二電極串120的目的。更甚者,可以配置各絕緣塊130的長度不同,但於第二方向D2的投影長度相同。First, the length of the insulating block 130 can be configured along with the insulating block 130. The angle A with the second direction D2 changes. Although the length of the insulating block 130 is not explicitly shown, it is to be understood that in one or more embodiments of the present invention, the projected length of the insulating block 130 in the second direction D2 may be configured to be larger than the first electrode string 110. The width of the connecting line 114 allows the insulating block 130 to cover at least part of the connecting line 114 for the purpose of isolating the first electrode string 110 from the second electrode string 120. Furthermore, the lengths of the insulating blocks 130 may be different, but the projection lengths in the second direction D2 are the same.
其次,亦可配置絕緣塊130的寬度隨著絕緣塊130 與第二方向D2的夾角A改變。雖然並未將絕緣塊130的長度明 確繪示出來,但需了解到,絕緣塊130於第一方向D1的投影長度可配置大於第二電極串120之連接線124的寬度,如此一來,可以將連接線114、連接線124兩者隔開,而達到隔離的目的。Secondly, the width of the insulating block 130 can also be configured along with the insulating block 130. The angle A with the second direction D2 changes. Although the length of the insulating block 130 is not It is to be noted that the projection length of the insulating block 130 in the first direction D1 can be greater than the width of the connecting line 124 of the second electrode string 120. Thus, the connecting line 114 and the connecting line 124 can be Separated to achieve the purpose of isolation.
再來,可以配置絕緣塊130的長軸方向LD與第二 方向D2的夾角A設計為不大於某個角度,例如60度,換句話說,長軸方向LD與連接線124的延伸方向的夾角A不大於60度。如此一來,可確保以使絕緣塊130於第二方向D2上的投影長度足夠讓連接線124藉由絕緣塊130跨過第一電極串110之連接線114,並保證連接線114與連接線124相互電性絕緣。須注意的是,在此60度僅為估計值,實際應用上隨著絕緣塊130的長寬不同、連接線114與連接線124的寬度不同,可以調整此角度至50度~70度等。Furthermore, the long-axis direction LD and the second of the insulating block 130 can be configured. The angle A of the direction D2 is designed to be no more than a certain angle, for example, 60 degrees, in other words, the angle A between the long-axis direction LD and the extending direction of the connecting line 124 is not more than 60 degrees. In this way, it can be ensured that the projection length of the insulating block 130 in the second direction D2 is sufficient for the connecting line 124 to straddle the connecting line 114 of the first electrode string 110 by the insulating block 130, and the connecting line 114 and the connecting line are ensured. 124 is electrically insulated from each other. It should be noted that the 60 degrees is only an estimated value. In practice, as the length and width of the insulating block 130 are different, and the width of the connecting line 114 and the connecting line 124 are different, the angle can be adjusted to 50 degrees to 70 degrees.
如此一來,藉由以上介紹的方式,可以克服當絕 緣塊130的夾角A較大時不容易隔絕連接線114與連接線124的問題。In this way, by the way described above, it can be overcome. When the angle A of the edge block 130 is large, the problem of the connection line 114 and the connection line 124 is not easily isolated.
於本創作之一或多個實施方式中,在絕緣塊130 的配置上,可以配置第一方向D1垂直於第二方向D2,且以第一方向D1為行、以第二方向D2為列,排列絕緣塊130。換句話說,絕緣塊130可以以第一方向D1與第二方向D2呈陣列排列。如此一來,絕緣塊130於第一方向D1上具有某一間距用以佈設感應電極112,絕緣塊130於第二方向D2上具有另一間距用以佈設感應電極122。但於其他實施方式中,第一方向D1可以與第二方向D2夾一定角度,而不互相垂直。In one or more embodiments of the present invention, in the insulating block 130 In the configuration, the first direction D1 may be perpendicular to the second direction D2, and the insulating block 130 may be arranged in a row in the first direction D1 and in the second direction D2. In other words, the insulating block 130 may be arranged in an array in the first direction D1 and the second direction D2. In this way, the insulating block 130 has a certain interval in the first direction D1 for arranging the sensing electrodes 112, and the insulating block 130 has another spacing in the second direction D2 for arranging the sensing electrodes 122. However, in other embodiments, the first direction D1 may be at an angle to the second direction D2 without being perpendicular to each other.
於本創作之一或多個實施方式中,第一電極串 110與第二電極串120之感應電極122的材料為透明導電材料。第一電極串110之連接線114的材料、第二電極串120之連接線124的材料可與感應電極122採用同樣的透明導電材料,亦可為金屬等不透明導電材料。絕緣塊130之材料可以是氧化矽、氮化矽或高分子聚合物等等,其厚度為大約0.1微米至大約5微米。In one or more embodiments of the present invention, the first electrode string The material of the sensing electrode 122 of the 110 and the second electrode string 120 is a transparent conductive material. The material of the connection line 114 of the first electrode string 110 and the material of the connection line 124 of the second electrode string 120 may be the same transparent conductive material as the sensing electrode 122, or may be an opaque conductive material such as metal. The material of the insulating block 130 may be yttrium oxide, tantalum nitride or a high molecular polymer or the like, and has a thickness of about 0.1 μm to about 5 μm.
由於通過第一電極串110與第二電極串120的交 會處的光受到絕緣塊130的影響,容易因介面反射而產生干涉,而有光強度隨視角變化等問題,而且人眼對陣列排列的視覺反應較強,因此當絕緣塊130排列一致時容易被人眼所觀察到。本實施方式透過設計絕緣塊130之長軸方向LD不同,分散了絕緣塊130在同一方向上的反射光線數量和強度,減少絕緣塊130因排列一致而容易被人眼觀察到干涉的問題,進而改善使用者觀查資訊的品質。Due to the intersection of the first electrode string 110 and the second electrode string 120 The light at the meeting is affected by the insulating block 130, and it is easy to interfere due to the interface reflection, and there is a problem that the light intensity changes with the viewing angle, and the visual response of the human eye to the array arrangement is strong, so when the insulating blocks 130 are aligned, it is easy. Observed by the human eye. In the present embodiment, by designing the insulating block 130 to have different longitudinal directions LD, the amount and intensity of reflected light of the insulating block 130 in the same direction are dispersed, and the problem that the insulating block 130 is easily observed by the human eye due to the uniform arrangement is reduced. Improve the quality of users' viewing information.
參照第2圖,第2圖為根據本創作之另一實施方式 之觸控面板100之示意圖。本實施方式大致上與第1圖之實施方式相同,差別在於:於本實施方式中,每一絕緣塊130與相鄰之絕緣塊130之長軸方向LD不同。Referring to FIG. 2, FIG. 2 is another embodiment according to the present creation. A schematic diagram of the touch panel 100. This embodiment is substantially the same as the embodiment of Fig. 1, except that in the present embodiment, each of the insulating blocks 130 is different from the longitudinal direction LD of the adjacent insulating block 130.
舉例而言,絕緣塊130b~130i環繞絕緣塊130a,每一絕緣塊130a~130i具有長軸方向LD,其中絕緣塊130a~130i的長軸方向LD並不互相平行,因此方向不同。For example, the insulating blocks 130b-130i surround the insulating block 130a, and each of the insulating blocks 130a-130i has a long-axis direction LD, wherein the long-axis directions LD of the insulating blocks 130a-130i are not parallel to each other, and thus the directions are different.
於此,長軸方向LD與第二方向D2可以具有夾角A,這些夾角Aa~Ai可具有等差或等比關係。例如絕緣塊130a ~130i的夾角A可以是0度、7.5度、15度、22.5度、30度、-7.5度、-15度、-22.5度、-30度。在此,隨著夾角A設置於第二方向D2的(上下)兩側不同,可以正負號表示夾角A。例如於第二方向D2的一側之夾角A以正值表示,於第二方向D2的另一側之夾角A以負值表示。以上角度中,負值僅用以表示長軸方向LD與第二方向D2的相對關係,不應以此限制夾角A的實際值。Here, the long axis direction LD and the second direction D2 may have an included angle A, and the included angles Aa to Ai may have an equal difference or an equal relationship. For example, insulating block 130a The angle A of ~130i may be 0 degrees, 7.5 degrees, 15 degrees, 22.5 degrees, 30 degrees, -7.5 degrees, -15 degrees, -22.5 degrees, -30 degrees. Here, as the angle A is set to be different on the upper and lower sides of the second direction D2, the angle A can be represented by a plus or minus sign. For example, the angle A between one side of the second direction D2 is represented by a positive value, and the angle A of the other side of the second direction D2 is represented by a negative value. In the above angles, the negative value is only used to indicate the relative relationship between the long-axis direction LD and the second direction D2, and the actual value of the included angle A should not be limited.
參照第3圖,第3圖為根據本創作之再一實施方式 之觸控面板100之示意圖。本實施方式大致上與第1圖之實施方式相同,差別在於:於本實施方式中,於第二方向D2上的多個絕緣塊130之長軸方向LD相同,且於第一方向D1上的至少二個絕緣塊130之長軸方向LD不同。換句話說,絕緣塊130之長軸方向LD僅於第一方向D1上變化。Referring to FIG. 3, FIG. 3 is still another embodiment according to the present creation. A schematic diagram of the touch panel 100. This embodiment is substantially the same as the embodiment of FIG. 1 except that in the present embodiment, the plurality of insulating blocks 130 in the second direction D2 have the same long-axis direction LD and are in the first direction D1. The at least two insulating blocks 130 have different longitudinal directions LD. In other words, the long-axis direction LD of the insulating block 130 changes only in the first direction D1.
其他相關的細節大致上與第1圖之實施方式相同,在此不再贅述。Other relevant details are substantially the same as those of the embodiment of FIG. 1 and will not be described herein.
當然,於其他實施方式中,亦可配置絕緣塊130之長軸方向LD僅於第二方向D2上變化。Of course, in other embodiments, the long axis direction LD of the insulating block 130 may be configured to vary only in the second direction D2.
參照第4圖,第4圖為根據本創作之又一實施方式之觸控面板100之示意圖。本實施方式大致上與第1圖之實施方式相同,差別在於:於本實施方式中,每一連接線124沿每一絕緣塊130之長軸方向LD延伸。Referring to FIG. 4, FIG. 4 is a schematic diagram of a touch panel 100 according to still another embodiment of the present invention. This embodiment is substantially the same as the embodiment of FIG. 1 except that in the present embodiment, each of the connection wires 124 extends in the longitudinal direction LD of each of the insulating blocks 130.
於本實施方式中,連接線124設置於絕緣塊130的中心,且每一連接線124沿絕緣塊130的長軸方向LD跨過每一絕緣塊130,以連接相鄰的感應電極122。在此,為了連接 相鄰的感應電極122,隨著絕緣塊130之長軸方向LD與第二方向D2的夾角A不同,連接線124的長度也不盡相同。In the present embodiment, the connection lines 124 are disposed at the center of the insulating block 130, and each of the connection lines 124 straddles each of the insulating blocks 130 along the long-axis direction LD of the insulating block 130 to connect the adjacent sensing electrodes 122. Here, in order to connect The adjacent sensing electrodes 122 have different lengths of the connecting wires 124 as the angle A between the major axis direction LD of the insulating block 130 and the second direction D2 is different.
於本實施方式中,連接線124以較長的路徑跨過 絕緣塊130,由於連接線124設置於絕緣塊130的長軸方向LD的中心軸位置,因此絕緣塊130可較佳地達到隔絕第一電極串110與第二電極串120之目的。In the present embodiment, the connecting line 124 spans over a longer path. The insulating block 130 preferably has the purpose of isolating the first electrode string 110 from the second electrode string 120 because the connecting line 124 is disposed at a central axis position of the long-axis direction LD of the insulating block 130.
參照第5圖,第5圖為根據本創作之再一實施方式 之觸控面板100之示意圖。為方便說明起見,於此省略了第一電極串110與多個第二電極串120。本實施方式與第1圖之實施方式相似,差別在於:於本實施方式中,沿第一方向D1分佈的絕緣塊130之長軸方向LD與第二方向D2具有多個夾角A,這些夾角A具有等差或等比關係。Referring to FIG. 5, FIG. 5 is still another embodiment according to the present creation. A schematic diagram of the touch panel 100. For convenience of explanation, the first electrode string 110 and the plurality of second electrode strings 120 are omitted herein. This embodiment is similar to the embodiment of FIG. 1 except that in the present embodiment, the longitudinal direction LD of the insulating block 130 distributed along the first direction D1 and the second direction D2 have a plurality of angles A, and these angles A Have an equivalence or equivalence relationship.
舉例而言,如圖所示,沿第一方向D1分佈的絕緣 塊130分別具有長軸方向LDa~LDi。長軸方向LDa~LDi與第二方向D2可以具有多個夾角Aa~Ai,這些夾角Aa~Ai可具有等差或等比關係。舉例而言,夾角Aa~Ai可以是30度、22.5度、15度、7.5度、0度、-7.5度、-15度、-22.5度、-30度。 於此,隨著夾角A設置於第二方向D2的(上下)兩側不同,可以正負號表示夾角A。例如於第二方向D2的一側之夾角Aa~Ad以正值表示,於第二方向D2的另一側之夾角Af~Ai以負值表示。以上角度中,負值僅用以表示長軸方向LDa~LDi與第二方向D2的相對關係,不應以此限制夾角Aa~Ai的實際值。For example, as shown, the insulation distributed along the first direction D1 The blocks 130 have long axis directions LDa to LDi, respectively. The long axis directions LDa to LDi and the second direction D2 may have a plurality of included angles Aa to Ai, and the included angles Aa to Ai may have an equal difference or an equal relationship. For example, the angles Aa~Ai may be 30 degrees, 22.5 degrees, 15 degrees, 7.5 degrees, 0 degrees, -7.5 degrees, -15 degrees, -22.5 degrees, -30 degrees. Here, as the angle A is set to be different on the upper and lower sides of the second direction D2, the angle A can be represented by a plus or minus sign. For example, the angles Aa to Ad of one side in the second direction D2 are represented by positive values, and the angles Af to Ai of the other side of the second direction D2 are represented by negative values. In the above angles, the negative value is only used to indicate the relative relationship between the long-axis directions LDa to LDi and the second direction D2, and the actual values of the included angles Aa to Ai should not be limited.
參照第6圖,第6圖為根據本創作之又一實施方式之觸控面板100之示意圖。本實施方式與第5圖之實施方式相 似,差別在於:本實施方式中,沿第二方向D2分佈的絕緣塊130之長軸方向LD與第二方向D2亦具有多個夾角A,夾角A具有等差或等比關係。Referring to FIG. 6, FIG. 6 is a schematic diagram of a touch panel 100 according to still another embodiment of the present invention. This embodiment is in contrast to the embodiment of FIG. The difference is that in the present embodiment, the major axis direction LD and the second direction D2 of the insulating block 130 distributed along the second direction D2 also have a plurality of included angles A, and the included angle A has an equal or equal relationship.
舉例而言,如圖所示,沿第二方向D2分佈的絕緣 塊130分別具有長軸方向LDa~LDi。長軸方向LDa~LDi與第二方向D2可以具有多個夾角Aa~Ai,這些夾角Aa~Ai可具有等差或等比關係。舉例而言,夾角Aa~Ai可以是30度、22.5度、15度、7.5度、0度、-7.5度、-15度、-22.5度、-30度。 於此,隨著夾角A設置於第二方向D2的(上下)兩側不同,可以正負號表示夾角A。例如於第二方向D2的一側之夾角Aa~Ad以正值表示,於第二方向D2的另一側之夾角Af~Ai以負值表示。以上角度中,負值僅用以表示長軸方向LDa~LDi與第二方向D2的相對關係,不應以此限制夾角Aa~Ai的實際值。For example, as shown, the insulation distributed along the second direction D2 The blocks 130 have long axis directions LDa to LDi, respectively. The long axis directions LDa to LDi and the second direction D2 may have a plurality of included angles Aa to Ai, and the included angles Aa to Ai may have an equal difference or an equal relationship. For example, the angles Aa~Ai may be 30 degrees, 22.5 degrees, 15 degrees, 7.5 degrees, 0 degrees, -7.5 degrees, -15 degrees, -22.5 degrees, -30 degrees. Here, as the angle A is set to be different on the upper and lower sides of the second direction D2, the angle A can be represented by a plus or minus sign. For example, the angles Aa to Ad of one side in the second direction D2 are represented by positive values, and the angles Af to Ai of the other side of the second direction D2 are represented by negative values. In the above angles, the negative value is only used to indicate the relative relationship between the long-axis directions LDa to LDi and the second direction D2, and the actual values of the included angles Aa to Ai should not be limited.
在其他實施例中,還可以結合如第5圖和第6圖的 排列方式,即沿第一方向D1分佈的絕緣塊130之長軸方向LD與第二方向D2具有多個夾角A,這些夾角A具有等差或等比關係。沿第二方向D2分佈的絕緣塊130之長軸方向LD與第二方向D2亦具有多個夾角A,夾角A具有等差或等比關係。其中夾角A沿第一方向D1的漸變關係可與沿第二方向D2的漸變關係相同或不同。In other embodiments, it is also possible to combine as shown in FIGS. 5 and 6 The arrangement manner, that is, the long-axis direction LD of the insulating block 130 distributed along the first direction D1 and the second direction D2 have a plurality of included angles A, and these included angles A have an equal or equal relationship. The long axis direction LD and the second direction D2 of the insulating block 130 distributed along the second direction D2 also have a plurality of angles A, and the angle A has an equal or equal relationship. The gradation relationship of the angle A in the first direction D1 may be the same as or different from the gradation relationship in the second direction D2.
如此一來,如前所述,由於長軸方向LDa~LDi 不盡相同,可避免絕緣塊130因排列一致造成容易被人眼觀察到的問題,進而改善使用者觀查資訊的品質。As a result, as mentioned above, due to the long axis direction LDa~LDi Differently, the problem that the insulating block 130 is easily observed by the human eye due to the alignment is avoided, thereby improving the quality of the user's observation information.
