Description
本發明係關於一種組合技術,且特別關於一種曲面式組合模組及其製作方法。 The present invention relates to a combination technology, and more particularly to a curved combination module and a manufacturing method thereof.
由於互聯網的發展,使用者對消費性電子之3C產品的黏著度提高,人眼或長時間攜帶使用的體驗性需求亦提高,因此,要求視覺化面積變大、窄邊框化可提高畫面視覺的寬廣度、重量減輕與直覺的手勢觸控行為可降低手持的疲憊感等的使用需求。各種曲面設計因應而生,例如平面邊緣弧角化及立體曲面等的產品設計等。然而,應用在觸控面板的貼合精度及高度的要求亦日趨嚴格,如第1圖之平面式組合模組所示,在一般平面貼合製程為了控制控制二玻璃基板10、12之間隙高度而使用流體光學膠14,並將流體光學膠14限制在框膠16所圍繞的空間中,但在固化流體光學膠14後,玻璃基板10、12之表面內因支撐性不足而有塌陷現象。此外,當平面貼合技術應用在異形且曲面的物件上時,會遇到如下缺點:首先是對位精度問題,二維平面線壓合工法貼合只需要求X-Y二維精度,然而,曲面對貼物為三維精度,需考慮Z軸對位精度。其次是面平整度問題,二維平面貼合中的面壓合及線壓合均以平均施壓方式控制貼合物表面的均勻平整度,然而,曲面包含凹凸等複雜且不定形的曲面,此外,對位精度影響亦會影響曲面表面均勻平整度並使得檢測難度提升。最後是貼合間隙控制問題,二維平面貼合可利用光學膠之膠量與刮刀高度配合來控制,然而,流體
狀的光學膠在曲面塗佈過程會因重力往下流,造成曲面間貼合間隙寬度難以均勻控制。
Due to the development of the Internet, the adhesion of users to consumer electronics 3C products has increased, and the need for human eyes or the experience of long-term portable use has also increased. Therefore, it is required to increase the visualization area and narrow the frame to improve the vision of the screen. The breadth, weight reduction, and intuitive gesture touch behavior can reduce the use of hand-held fatigue. Various curved surface designs have emerged accordingly, such as product design such as flat edge arc cornering and three-dimensional curved surfaces. However, the requirements for the precision and height of the touch panel are becoming stricter. As shown in the planar assembly module in Figure 1, in the general planar bonding process, the gap height between the two

以下請參閱第2圖,並介紹本發明之曲面式組合模組之第一實施例,其包含一第一曲面透明基板18、複數個間隔物(spacer)20、一框膠22、一光學膠23與一第二曲面透明基板24,其中框膠22與光學膠23皆為紫外光感膠,光學膠23可為液態光學膠(LOCA),第一曲面透明基板18與第二曲面透明基板24可為玻璃基板,但本發明不限於此。第一曲面透明基板18具有一內區域26與一外區域28,外區域28環繞內區域26。所有間隔物20與光學膠23均勻設於內區域26上,每一間隔物20的截面直徑為5~60微米(μm),所有間隔物20之尺寸的變異係數(coefficient of variation)小於或等於7%,其中變異係數=(標準差/平均值×100%)。框膠22設於外區域28上,並環繞所有間隔物20與光學膠23。第二曲面透明基板24設於所有間隔物20、框膠22與光學膠23上,以藉此與第一曲面透明基板18完成曲面貼合,並維持固定第一曲面透明基板18與第二曲面透明基板24之間的間隙。本發明所使用的間隔物20為塑膠系微粒子、玻璃系微粒子或矽氧系微粒子,其中塑膠系微粒子例如為壓克力樹脂粒子,玻璃系微粒子例如為石英粒子,矽氧系微粒子例如為矽氧類高分子(Siloxane polymer)粒子。矽氧系微粒子在形狀上較為整齊均勻,也容易產生穩定的間隙,相較塑膠系微粒子之灑佈量少1/3~1/5,同時具有低溫發泡的優點,應用於液晶面板時,與液晶有良好的相容性與穩定性,不易在低溫下產生收縮造成的重力問題使液晶面板上產生色差。
Please refer to Figure 2 below and introduce the first embodiment of the curved modular module of the present invention, which includes a first curved
間隔物20可為珠(bead)狀或纖維(Fibrous)狀。在截面直
徑為5~60微米的條件下,所有間隔物20有均勻的尺寸分佈,並保持彼此之間的間隙恆定且均勻。在間隔物20之化學性質上,即使在攝氏-40至200度的溫度下也能保持穩定。間隔物20也不溶於有機溶劑。此間隔物20並非完全透明,是根據組成材料而定。由於人眼的辨識率為大於100微米,因此當間隔物20的截面直徑控制在小於100微米時,人眼是無法分辨散佈在第一曲面透明基板18與第二曲面透明基板24之間的間隔物20的。
The
本發明提供間隔物20來控制貼合高度,並維持整體貼合面之高度一致。根據間隔物20之大小均一性及在第一曲面透明基板18與第二曲面透明基板24之間的位置,決定第一曲面透明基板18與第二曲面透明基板24之間的間隙之高度。由於間隔物20的截面直徑為5~60微米,故第一曲面透明基板18與第二曲面透明基板24之間的間隙之高度同樣為5~60微米,並維持恆定,並使光學膠23使用量降低,進而降低材料成本。因為所有間隔物20為等高之微米等級尺寸,所以可應用在光學特性要求的面板產業。其次,因能維持固定第一曲面透明基板18與第二曲面透明基板24之間的間隙,故能達到整體表面高度均一之平整性,且維持第一曲面透明基板18與第二曲面透明基板24之中心高度的支撐性,因此能有效控制曲面貼合高度的精準度、降低複雜曲面貼合的困難與適用於曲面貼合之製程,可應用於車用面板、手機面板或虛擬實境眼鏡等。
The present invention provides

23。最後,如第5圖所示,形成第二曲面透明基板24於光學膠23、所有間隔物20與框膠22上,並以紫外光照射框膠22與光學膠23,以硬化框膠22與光學膠23,以藉所有間隔物20、框膠22及光學膠23完成第二曲面透明基板24與第一曲面透明基板18之曲面貼合,並維持固定第一曲面透明基板18與第二曲面透明基板24之間的間隙。

在第一實施例中,可以缺少光學膠23,同樣可以達到相同目的。如此一來,在第4圖之步驟中,可以省略形成光學膠23於內區域26上之步驟,以利用框膠22環繞所有間隔物20。另在第5圖之步驟中,形成第二曲面透明基板24於所有間隔物20與框膠22上,並以紫外光照射框膠22,以硬化框膠22,以藉所有間隔物20與框膠22完成第二曲面透明基板24與第一曲面透明基板18之曲面貼合,並維持固定第一曲面透明基板18與第二曲面透明基板24之間的間隙。
In the first embodiment, the
以下請參閱第6圖,並介紹本發明之曲面式組合模組之第二實施例,第二實施例與第一實施例差別在於第二實施例更包含一感測層30,其係設於所有間隔物20與第一曲面透明基板18之內區域26之間,且設於光學膠23與第一曲面透明基板18之內區域26之間,框膠22環繞感測層30。感測層30可由透明電極串列所組成,使曲面式組合模組之第二實施例可以作為一曲面式觸控感測模組,可達成與第一實施例之相同目的。

以下請參閱第14圖,並介紹本發明之曲面式組合模組之第四實施例,以作為一液晶觸控模組,其包含一第一曲面透明基板34、一第一框膠36、一感測層38、一光學膠40、複數個第一間隔物(spacer)42與一曲面式液晶模組44。曲面式液晶模組44包含一第二曲面透明基板46、一第二框膠48、一液晶50、複數個第二間隔物52與一第三曲面透明基板54。第一框膠36、光學膠40與第二框膠48皆為紫外光感膠,光學膠40可為液態光學膠(LOCA),感測層38可由透明電極串列所組成,第二曲面透明基板46與第三曲面透明基板54可為玻璃基板,但本發明不限於此。第一曲面透明基板34具有一第一內區域56與一第一外區域58,第一外區域58環繞第一內區域56。感測層38設於第一內區域56上,第一框膠36設於第一外區域58上,並環繞感測層38。所有第一間隔物42與光學膠40均勻設於感測層38與第一內區域56上,每一第一間隔物42的截面直徑為5~60微米,所有第一間隔物42之尺寸的變異係數小於或等於7%。第一框膠36設於第一外區域58上,並環繞所有第一間隔物42與光學膠40。第二曲面透明基板46設於所有第一間隔物42、第一框膠36與光學膠40上,以藉此與第一曲面透明基板34完成曲面貼合,並維持固定第一曲面透明基板34與第二曲面透明基板46之間的間隙。第二曲面透明基板46具有一第二內區域60與一第二外區域62,第二外區域62環繞第二內區域60。第二框膠48設於第二外區域62上。所有第二間隔物52與液晶50均勻設於第二內區域60上,每一第二間隔物52的截面直徑為5~60微米,所有第二間隔物52之尺寸的變異係數小於或等於7%,其中變異係數=(標準差/平均值×100%)。第二框膠48環繞所有第二間隔物52與液晶50。第三曲面透明基板54設於所有第二間隔物52、第二框膠48與液晶50上,以藉此與第二曲面透明基板46完成曲面貼合,並維持固定第三曲
面透明基板54與第二曲面透明基板46之間的間隙。本發明所使用的第一間隔物42與第二間隔物52為塑膠系微粒子、玻璃系微粒子或矽氧系微粒子,其中塑膠系微粒子例如為壓克力樹脂粒子,玻璃系微粒子例如為石英粒子,矽氧系微粒子例如為矽氧類高分子(Siloxane polymer)粒子。矽氧系微粒子在形狀上較為整齊均勻,也容易產生穩定的間隙,相較塑膠系微粒子之灑佈量少1/3~1/5,同時具有低溫發泡的優點,應用於液晶面板時,與液晶有良好的相容性與穩定性,不易在低溫下產生收縮造成的重力問題使液晶面板上產生色差。
Please refer to Figure 14 below and introduce the fourth embodiment of the curved combination module of the present invention as a liquid crystal touch module, which includes a first curved
第一間隔物42與第二間隔物52可為珠(bead)狀或纖維(Fibrous)狀。在截面直徑為5~60微米的條件下,所有第一間隔物42與所有第二間隔物52有均勻的尺寸分佈,並保持彼此之間的間隙恆定且均勻。在第一間隔物42與第二間隔物52之化學性質上,即使在攝氏-40至200度的溫度下也能保持穩定。第一間隔物42與第二間隔物52也不溶於有機溶劑。第一間隔物42與第二間隔物52並非完全透明,是根據組成材料而定。由於人眼的辨識率為大於100微米,因此當第一間隔物42與第二間隔物52的截面直徑控制在小於100微米時,人眼是無法分辨散佈之第一間隔物42與第二間隔物52的。
The
本發明提供第一間隔物42與第二間隔物52來控制貼合高度,並維持整體貼合面之高度一致。根據第一間隔物42與第二間隔物52之大小均一性及在第一曲面透明基板18與第二曲面透明基板24之間的位置,決定第一曲面透明基板34、第二曲面透明基板46與第三曲面透明基板54之間的間隙之高度。由於第一間隔物42與第二間隔物52的截面直徑為5~60微米,故第一曲面透明基板34與第二曲面透明基板46之間的間隙之高度及第二曲面透明基板46與第三曲面透明基板54之間的間隙之高度同樣為5~60微米,並維持恆定。因為所有第一間隔物42或所有
第二間隔物52為等高之微米等級尺寸,所以可應用在光學特性要求的面板產業。其次,因能維持固定第一曲面透明基板34與第二曲面透明基板46之間的間隙及第二曲面透明基板46與第三曲面透明基板54之間的間隙,故能達到整體表面高度均一之平整性,且維持第一曲面透明基板34、第二曲面透明基板46與第三曲面透明基板54之中心高度的支撐性,因此能有效控制曲面貼合高度的精準度、降低複雜曲面貼合的困難與適用於曲面貼合之製程。
The present invention provides the

請參閱第18圖、第19圖、第20圖與第21圖。第18圖以曲面式組合模組之第一實施例為例,其中第一曲面透明基板18與第二曲面透明基板24之間的傾斜角為0°。第一曲面透明基板18與第二曲面透明基板24的厚度皆為1公釐(mm),第一曲面透明基板18與第二曲面透明基板24皆為玻璃基板,第一曲面透
明基板18與第二曲面透明基板24之間的間隙固定為50微米,光學膠23之折射率為1.5-1.53。由第19圖可知,中心光線的出光角度相對Z軸為0°,0°之邊緣光線與中心光線的最大角度差為0.43°。由第20圖與第21圖可知,二維座標軸的曲線接近線性,表示第一曲面透明基板18與第二曲面透明基板24之左右的光路是對稱的。
Please refer to Figure 18, Figure 19, Figure 20 and Figure 21. FIG. 18 takes the first embodiment of the curved composite module as an example, in which the inclination angle between the first curved
請參閱第22圖、第23圖、第24圖與第25圖。第22圖表示傾斜5-10度之曲面式組合模組。此曲面式組合模組包含二玻璃基板64、66與位於其之間的一光學膠68。玻璃基板64、66互相傾斜的角度由右而左是從5°傾斜到10°。玻璃基板64、66的厚度皆為1公釐(mm),玻璃基板64、66的間隙之變化為20-80微米,光學膠68之折射率為1.5-1.53。由第23圖可知,中心光線的出光角度相對Z軸為7.4°,8.78°的邊緣光線與中心光線之最大角度差為1.38°。由第24圖與第25圖可知,二維座標軸的曲線為拋物線,表示貼合的傾斜角已影響玻璃基板64、66之左右的光路表現,其中最大光線角度偏折為8.78°。
Please refer to Figure 22, Figure 23, Figure 24 and Figure 25. Figure 22 shows a curved modular module tilted 5-10 degrees. The curved combined module includes two
請參閱第22圖、第26圖、第27圖與第28圖。由第26圖可知,中心光線的出光角度相對Z軸為14.8°,17.88°的邊緣光線與中心光線之最大角度差為3.08°。由第27圖與第28圖可知,二維座標軸的曲線為拋物線,表示貼合的傾斜角已影響玻璃基板64、66之左右的光路表現,其中最大光線角度偏折為17.88°。
Please refer to Figure 22, Figure 26, Figure 27 and Figure 28. It can be seen from Fig. 26 that the exit angle of the central ray is 14.8° relative to the Z axis, and the maximum angle difference between the 17.88° edge ray and the central ray is 3.08°. From Figures 27 and 28, it can be seen that the curve of the two-dimensional coordinate axis is a parabola, indicating that the inclination angle of the bonding has affected the optical path performance of the
換言之,本發明是利用間隔物以控制曲面貼合高度,來達到均勻的曲面得到最好的光學特性,當曲面貼合高度皆均勻時,曲面中心與邊緣的光學特性並不會發生嚴重的光的偏折現象。然而,當曲面貼合高度傾斜時,曲面中心與邊緣的光學特性會發生光偏折而引發視覺上的像差。 In other words, the present invention uses spacers to control the bonding height of the curved surface to achieve a uniform curved surface and obtain the best optical characteristics. When the curved surface bonding height is uniform, the optical characteristics of the center and edge of the curved surface will not cause serious light The deflection phenomenon. However, when the curved surface is highly inclined, the optical characteristics of the center and the edge of the curved surface will be deflected and cause visual aberrations.
綜上所述,本發明形成複數個間隔物於二曲面透明基板之間,以維持固定二曲面透明基板之間的間隙,以達到整體表面高度均一之平整性,並有效控制曲面貼合高度的精準度,及降低複雜曲面貼合的困難。同時利用間隔物之截面直徑,使光學膠使用量降低,進而降低材料成本。 In summary, the present invention forms a plurality of spacers between the two-curved transparent substrates to maintain and fix the gap between the two-curved transparent substrates to achieve uniformity of the overall surface height and effectively control the surface bonding height Accuracy, and reduce the difficulty of fitting complex curved surfaces. At the same time, the cross-sectional diameter of the spacer is used to reduce the amount of optical glue used, thereby reducing material costs.
