圖2A是依照本發明一實施例的電子裝置的製造方法流程示意圖,圖2B是依照本發明一實施例的電子裝置的製造方法示意圖。如圖2所示,在本實施例中,電子裝置的製造方法可以包括預切割步驟S200、第一壓合步驟S210、第一裂片步驟S220、第一封膠步驟S230、第二壓合步驟S240、第一封膠斜角切割步驟S250、第二裂片步驟S260、第二封膠步驟S270。 2A is a schematic flowchart of a manufacturing method of an electronic device according to an embodiment of the present invention, and FIG. 2B is a schematic diagram of a manufacturing method of an electronic device according to an embodiment of the present invention. As shown in FIG. 2 , in this embodiment, the manufacturing method of an electronic device may include a pre-cutting step S200 , a first pressing step S210 , a first splitting step S220 , a first sealing step S230 , and a second pressing step S240 , the first sealing glue bevel cutting step S250, the second splitting step S260, and the second glue sealing step S270.
請一併參照圖2A與圖2B,首先,液晶顯示面板母片100a包括第一基板110、第二基板120、位於第一基板110與第二基板120之間的液晶層130以及環繞液晶層的框膠200。在圖2B的預切割步驟S200中,依使用者的需求進行液晶顯示面板100所需尺寸而設定出液晶顯示面板母片100a的第一預切割線C1及第二預切割線C2的位置。具體而言是將面板成品(即液晶顯示面板母片100a)以常規的切割器材於基板上沿第一方向D1及第二方向D2的第一預切割線C1及第二預切割線C2切割出預定大小的切口,以利後續進行裂片步驟,在預切割步驟S200中,液晶顯示面板100並未完全切斷而僅於預設位置切劃深度小於基板厚度的溝槽。在本實施方式中,例如是使用刀輪或雷射光等切割設備進行切割,但不以此為限。接著,將預切割步驟S200後的液晶顯示面板母片100a送入壓合塗膠機M中,以進行第一壓合步驟S210與第一裂片步驟S220。
2A and 2B together, first, the liquid crystal display panel mother sheet 100a includes a
如圖2B中第一壓合步驟S210的示意圖,液晶顯示面板
母片100a首先在壓合塗膠機M進行第一壓合步驟S210,壓合塗膠機M在垂直方向移動,可以夾持的方式垂直地夾持欲保留的液晶顯示面板母片的保留區P,並於壓合塗膠機M內沿著第一預切割線C1對液晶顯示面板母片100a進行壓合。具體而言,將第一預切割線C1對齊壓合塗膠機M的壓合邊緣,使後述步驟需裂片去除的非保留區Q露出於壓合塗膠機M之外。保留區P與非保留區Q是以第一預切割線C1與第二預切割線C2為分界定義液晶顯示面板100需保留的大小。在壓合塗膠機M進行第一壓合步驟S210的同時,對外部進行加壓使外部壓力增加,以利於後續的製程流程。
As shown in the schematic diagram of the first lamination step S210 in FIG. 2B , the liquid crystal display panel
The mother sheet 100a is firstly subjected to the first pressing step S210 in the pressing and gluing machine M. The pressing and gluing machine M is moved in the vertical direction, and the reserved area of the master sheet of the liquid crystal display panel to be retained can be vertically clamped in a clamping manner. P, and press the liquid crystal display panel mother sheet 100a along the first pre-cutting line C1 in the pressing and gluing machine M. Specifically, the first pre-cut line C1 is aligned with the pressing edge of the pressing and gluing machine M, so that the non-reserved area Q that needs to be removed in the steps described later is exposed outside the pressing and gluing machine M. The reserved area P and the non-reserved area Q use the first pre-cut line C1 and the second pre-cut line C2 as the boundary to define the size to be reserved for the liquid
接著,請參照圖2B中第一裂片步驟S220的示意圖,在第一壓合步驟S210後以折片的方式沿著第一預切割線C1對液晶顯示面板母片100a進行裂片,以去除露出於壓合塗膠機M之外的液晶顯示面板母片100a的非保留區Q,形成液晶顯示面板保留子片100b。裂片的方式例如以外力作用於先前預切割步驟S200切割出第一方向D1的裂痕處,但本發明並沒有特別限定於何種裂片方式。液晶顯示面板母片100a於第一裂片步驟S220中於裂片斷面處形成暴露出液晶層的第一邊緣E1,此外,由於在第一壓合步驟S210即對液晶顯示面板母片100a進行加壓,因此第一邊緣E1的內部液晶壓力與外部壓力平衡,防止液晶層的液晶從切口處流出。 Next, please refer to the schematic diagram of the first splitting step S220 in FIG. 2B , after the first pressing step S210 , split the liquid crystal display panel mother sheet 100 a along the first pre-cut line C1 in a folded manner to remove the exposed The non-reserved area Q of the liquid crystal display panel mother sheet 100a outside the glue applicator M is pressed to form the liquid crystal display panel reserved sub-piece 100b. The method of splitting is, for example, an external force acts on the cracks in the first direction D1 cut in the previous pre-cutting step S200, but the present invention is not particularly limited to which splitting method. In the first splitting step S220, the liquid crystal display panel mother sheet 100a forms a first edge E1 exposing the liquid crystal layer at the split section. In addition, since the liquid crystal display panel mother sheet 100a is pressed in the first laminating step S210 , so the internal liquid crystal pressure of the first edge E1 is balanced with the external pressure, preventing the liquid crystal of the liquid crystal layer from flowing out from the cutout.
請參照圖2B中第一裂片步驟S230的示意圖,接著對液
晶顯示面板保留子片100b的切割邊進行第一封膠步驟S230,於第一邊緣E1塗上側封膠300形成第一膠體310,第一膠體310如前述圖1C覆蓋第一基板110與第二基板120的側表面,並且在液晶顯示面板保留子片100b中,框膠200與第一膠體310環繞液晶層130。
Please refer to the schematic diagram of the first split step S230 in FIG. 2B , and then the liquid
The crystal display panel retains the cutting edge of the sub-piece 100b to perform the first sealing step S230, and coats the
請參照圖2B中第二壓合步驟S240的示意圖,第一封膠步驟S230結束後可將液晶顯示面板保留子片100b旋轉一角度或移動後將面板非保留區Q露出於壓合塗膠機M之外,旋轉角度例如在本實施例為90°。
Please refer to the schematic diagram of the second lamination step S240 in FIG. 2B , after the first glue sealing step S230 is completed, the liquid crystal display
接著以第二方向D2的第二預切割線C2對齊壓合塗膠機M的壓合邊緣後進行第二壓合步驟S240,如同前述第一壓合步驟S210,第二壓合步驟S240中壓合塗膠機M在垂直方向移動,以夾持的方式垂直地夾持液晶顯示面板保留子片100b的保留區P,並且於壓合塗膠機M內沿第二預切割線C2進行壓合,使液晶顯示面板保留子片100b的非保留區Q露出於壓合塗膠機M之外,形成液晶顯示面板保留子片100b,在此步驟中即以第二預切割線C2為分界進行壓合塗膠機M的壓合。 Then, the second pre-cutting line C2 in the second direction D2 is aligned with the pressing edge of the glue coating machine M, and then the second pressing step S240 is performed. Similar to the first pressing step S210 described above, the second pressing step S240 is pressed in the middle. The gluing machine M moves in the vertical direction, vertically clamps the reserved area P of the liquid crystal display panel retaining sub-piece 100b in a clamping manner, and presses the gluing machine M along the second pre-cut line C2 , the non-reserved area Q of the liquid crystal display panel reserved sub-piece 100b is exposed outside the lamination and gluing machine M to form the liquid crystal display panel reserved sub-piece 100b. In this step, the second pre-cut line C2 is used as the boundary for pressing Press together with the glue applicator M.
特別的是,在進行第二裂片步驟S260之前,先對液晶顯示面板保留子片100b的第一膠體額外進行第一封膠斜角切割步驟S250。詳細而言,可先同時參照圖3,圖3是依照本發明的一實施例電子裝置的製造方法中第一膠體310與第二膠體320於第一封膠斜角切割步驟S250與第二封膠步驟S270時的上視示意圖。如
圖2B與圖3所示,第一封膠斜角切割步驟S250中,在第一邊緣E1的第一膠體310以刀片切出一個方向的斜角切口BC。刀片硬度小於第一基板110與第二基板120,使第一基板110與第二基板120不會留下刻痕。
In particular, before the second splitting step S260, the first glue bevel cutting step S250 is additionally performed on the first glue of the liquid crystal display
請參照圖2B中第二裂片步驟S260的示意圖以及圖3。如同前述第一裂片步驟進行第二裂片步驟S260,沿第二邊緣E2的第二預切割線C2對液晶顯示面板進行裂片,以折片的方式去除第二方向非保留區Q的面板,形成液晶顯示面板保留子片100c,在此步驟中液晶顯示面板保留子片100c於被裂片處形成暴露出液晶層的第二邊緣E2。此外,由於在第二壓合步驟S240即對液晶顯示面板母片100b進行加壓,因此第二邊緣E2的內部液晶壓力與外部壓力平衡,防止液晶層的液晶從切口處流出。
Please refer to the schematic diagram of the second splitting step S260 in FIG. 2B and FIG. 3 . The second splitting step S260 is performed as in the first splitting step, the liquid crystal display panel is split along the second pre-cut line C2 of the second edge E2, and the panel in the non-reserved area Q in the second direction is removed by folding to form a liquid crystal display panel. The display panel retains the sub-sheet 100c, and in this step, the liquid crystal display panel retains the sub-sheet 100c to form a second edge E2 at the position to be split, exposing the liquid crystal layer. In addition, since the liquid crystal display
請參照圖2B中第二封膠步驟S270的示意圖以及圖3。在第二封膠步驟S270中,於液晶顯示面板保留子片100c的第二邊緣E2與斜角切口BC塗上側封膠形成第二膠體320,第二膠體320如前述覆蓋第一基板110與第二基板120的側表面,並且在第二膠體320、框膠200與第一膠體310環繞液晶層130,使液晶密封於液晶層130之中,至此完成預定尺寸與形狀的液晶顯示面板100。本實施例的電子裝置例如可為前述圖1E的雙側側封邊框液晶電子裝置20。
Please refer to the schematic diagram of the second sealing step S270 in FIG. 2B and FIG. 3 . In the second encapsulation step S270, a side encapsulant is applied on the second edge E2 and the bevel cut BC of the liquid crystal display panel retaining sub-piece 100c to form a
為了更清楚說明本發明之一實施例電子裝置的製造方法,以下以圖3更清楚地針對第一膠體310與第二膠體320的形成方
法進行說明。請參照圖3,圖3是依照本發明的一實施例電子裝置的製造方法上視示意圖。首先,將第一邊緣E1的延伸方向與第二邊緣E2的延伸方向之間夾角定義為X,斜角切口BC的延伸方向與第二邊緣E2的第二預切割線C2的夾角定義為Y。在本實施例中,第一膠體310的膠寬為W1,第二膠體320的膠寬為W2。如上述步驟,本實施例經過第一裂片步驟S220及第一封膠步驟S230後,可獲得液晶顯示面板上第一邊緣E1的延伸方向與第二邊緣E2的延伸方向之間夾角X,並進行第一封膠斜角切割步驟S250,以刀片沿著預定的斜角切口BC切割第一膠體310,並以第二裂片步驟S260裂片液晶顯示面板的非保留區而得到夾角Y的缺口。接著,進行第二封膠步驟S270,第二邊緣E2形成第二膠體320,使得液晶顯示面板100的第一膠體310與第二膠體320於對接處形成第一對接界線400。若沒有進行第一封膠斜角切割步驟S250而直接塗上第二膠體320,則轉角處會因表面張力而具有轉角圓化(Corner Rounding)的現象,進而導致外觀不佳,且製成的面板有信賴度(Reliability)的疑慮。斜角切口BC的延伸方向與第二邊緣的第二預切割線的夾角Y的大小會影響第一膠寬W1與第二膠寬W2的寬度,進而影響兩者之比例。
In order to more clearly illustrate the manufacturing method of an electronic device according to an embodiment of the present invention, the following will use FIG. 3 to more clearly focus on the formation method of the
請參照圖4,圖4是當液晶顯示面板預設形狀為四邊形且邊緣呈直角(即夾角X)為90°時,切割角度與膠寬的關係圖表。橫軸為斜角切口BC的延伸方向與第二邊緣的第二預切割線的夾角Y,縱軸為第二膠寬與第一膠寬之比W2/W1。在本發明的實施 例中,夾角與膠寬具有圖4的關係,更清楚而言,液晶顯示面板預設邊緣角度X、切割角度Y之間滿足下述關係式。 Please refer to FIG. 4 . FIG. 4 is a graph showing the relationship between the cutting angle and the glue width when the liquid crystal display panel is preset in a quadrilateral shape and the edges are at right angles (ie, the included angle X) is 90°. The horizontal axis is the included angle Y between the extending direction of the bevel cut BC and the second pre-cut line of the second edge, and the vertical axis is the ratio W2/W1 of the second glue width to the first glue width. in the implementation of the present invention In the example, the included angle and the glue width have the relationship shown in FIG. 4 . More specifically, the predetermined edge angle X and the cutting angle Y of the liquid crystal display panel satisfy the following relationship.
其中X、Y較佳為滿足下述式(1):Y=[(360°-X)*1/2]±20°......(1)。 Among them, X and Y preferably satisfy the following formula (1): Y=[(360°-X)*1/2]±20°...(1).
X、Y更佳為滿足下述式(2):Y=(360°-X)*1/2......(2)。 More preferably, X and Y satisfy the following formula (2): Y=(360°-X)*1/2...(2).
在本實施例中,當夾角X為90°時,Y較佳的範圍為120°至155°,最佳的範圍為135°。若夾角Y大於155°時,會導致塗上第二膠體時的膠寬W2過窄,而有信賴度(Reliability)的疑慮。若夾角Y小於120°時,會導致塗上第二膠體時膠寬W2過寬,使轉角處形成尖角而易發生撞裂(Chipping),且外觀不佳。 In this embodiment, when the included angle X is 90°, the preferable range of Y is 120° to 155°, and the best range is 135°. If the included angle Y is greater than 155°, the glue width W2 when the second colloid is applied will be too narrow, and there will be doubts about reliability. If the included angle Y is less than 120°, the glue width W2 will be too wide when the second colloid is applied, resulting in sharp corners at the corners, which are prone to chipping and poor appearance.
