Description
本發明涉及一種液晶面板,特別涉及用於平板顯示器製造領域之液晶面板。 The present invention relates to a liquid crystal panel, and more particularly to a liquid crystal panel used in the field of flat panel display manufacturing.
平板顯示裝置之製造過程中,通常需要利用雷射劃片器(Laser Scribe)對一個較大尺寸之面板進行切割。 In the manufacturing process of flat panel display devices, it is usually necessary to use a laser scribe to cut a larger sized panel.
請參見圖1,一種用於雷射切割之液晶面板10包括薄膜電晶體(Thin Film Transistor,TFT)玻璃板11以及位於該薄膜電晶體玻璃板11一側之彩色濾光片(Color Filter,CF)玻璃板12。該薄膜電晶體玻璃板11包括複數個矩形薄膜電晶體單元110,且該薄膜電晶體單元110包括中心區域1102及線路區域1104。該複數個薄膜電晶體單元110按同一方向(如圖1所示y方向)排列,也即,從圖1之角度來看,每一個薄膜電晶體單元110之線路區域1104均位於該薄膜電晶體單元110之中心區域1102之右側,每一個薄膜電晶體單元110之線路區域1104與跟其相鄰之薄膜電晶體單元110之中心區域1102相鄰。該每個薄膜電晶體單元110之中心區域1102藉由環形框膠13與該彩色濾光片玻璃板12相互黏接。 Referring to FIG. 1, a liquid crystal panel 10 for laser cutting comprises a Thin Film Transistor (TFT) glass plate 11 and a color filter (Color Filter, CF) on the side of the thin film transistor glass plate 11. ) Glass plate 12. The thin film transistor glass plate 11 includes a plurality of rectangular thin film transistor units 110, and the thin film transistor unit 110 includes a central region 1102 and a line region 1104. The plurality of thin film transistor units 110 are arranged in the same direction (in the y direction as shown in FIG. 1), that is, from the perspective of FIG. 1, the line region 1104 of each of the thin film transistor units 110 is located in the thin film transistor. To the right of the central region 1102 of the cell 110, the line region 1104 of each of the thin film transistor units 110 is adjacent to the central region 1102 of the thin film transistor unit 110 adjacent thereto. The central region 1102 of each of the thin film transistor units 110 is bonded to the color filter glass plate 12 by the annular frame glue 13 and the color filter glass plate 12.
採用雷射劃片器對該液晶面板10進行加工,通常係先沿虛線14朝x軸方向進行預切割,再沿虛線15朝y軸方向進行預切割。然而,對該種液晶面板10進行x軸方向預切割之過程中,由於液晶面板10上x軸方向切割道相鄰兩側具有結構差異,即切割道一側之薄膜電晶體單元110之中心 區域1102設置有與彩色濾光片玻璃板12相互黏接之框膠13,而另一側之薄膜電晶體單元110之線路區域1104沒有設置與彩色濾光片玻璃板12相互黏接之框膠13,該結構差異會導致液晶面板10內部之應力不同,因此雷射沿虛線14切過之薄膜電晶體單元110之間區域將會出現明顯之裂紋16,該裂紋16通常會延伸至未設置框膠13之薄膜電晶體單元110之線路區域1104,從而導致液晶面板雷射切割製程之良率較低。 The liquid crystal panel 10 is processed by a laser scriber, and is usually pre-cut along the broken line 14 in the x-axis direction, and then pre-cut along the broken line 15 in the y-axis direction. However, in the process of pre-cutting the liquid crystal panel 10 in the x-axis direction, since the adjacent sides of the dicing street in the x-axis direction on the liquid crystal panel 10 have a structural difference, that is, the center of the thin film transistor unit 110 on the side of the dicing street The region 1102 is provided with a sealant 13 adhered to the color filter glass plate 12, and the line region 1104 of the thin film transistor unit 110 on the other side is not provided with a sealant bonded to the color filter glass plate 12 13, the difference in structure causes the stress inside the liquid crystal panel 10 to be different, so that a region 16 between the thin film transistor unit 110 which is cut by the laser along the broken line 14 will have a distinct crack 16, which usually extends to the unset frame. The line region 1104 of the thin film transistor unit 110 of the glue 13 results in a lower yield of the liquid crystal panel laser cutting process.
有鑒於此,提供一種適用於高良率雷射切割之液晶面板實為必要。 In view of this, it is necessary to provide a liquid crystal panel suitable for high-rate laser cutting.
下面將以實施例說明一種適用於高良率雷射切割之液晶面板。 A liquid crystal panel suitable for high-rate laser cutting will be described below by way of example.
一種液晶面板,其包括薄膜電晶體玻璃板、環形第一框膠及位於該薄膜電晶體玻璃板一側之彩色濾光片玻璃板。該薄膜電晶體玻璃板包括複數個沿一第一方向及一不同於該第一方向之第二方向呈陣列狀排布之薄膜電晶體單元;該複數個薄膜電晶體單元相互間隔並分別包括一中心區域及一線路區域。該中心區域包括上側邊、與該上側邊相對的下側邊、左側邊及與該左側邊相對的右側邊,該線路區域位於該左側邊或者該右側邊。該第一方向與該上側邊及該下側邊的長度方向一致,該第二方向與該左側邊及該右側邊的長度方向一致。該第一方向上之任意兩相鄰薄膜電晶體單元中,其中一個薄膜電晶體單元之線路區域與另一個薄膜電晶體單元之線路區域相 鄰設置,或者,其中一個薄膜電晶體單元之中心區域與另一個薄膜電晶體單元之中心區域相鄰設置;該中心區域之邊界處藉由該第一框膠與該彩色濾光片玻璃板相黏接。 A liquid crystal panel comprising a thin film transistor glass plate, an annular first frame sealant, and a color filter glass plate on a side of the thin film transistor glass plate. The thin film transistor glass plate includes a plurality of thin film transistor units arranged in an array along a first direction and a second direction different from the first direction; the plurality of thin film transistor units are spaced apart from each other and include one respectively Central area and a line area. The central region includes an upper side, a lower side opposite to the upper side, a left side, and a right side opposite the left side, the line area being located on the left side or the right side. The first direction coincides with the longitudinal direction of the upper side and the lower side, and the second direction coincides with the longitudinal direction of the left side and the right side. In any two adjacent thin film transistor units in the first direction, a line region of one of the thin film transistor units and a line region of another thin film transistor unit Adjacently disposed, or a central region of one of the thin film transistor units is disposed adjacent to a central region of another thin film transistor unit; the boundary of the central region is aligned with the color filter glass plate by the first sealant Bonding.
相較於先前技術,該液晶面板之薄膜電晶體單元之中心區域形成有與彩色濾光片玻璃板相黏接之環形框膠,而薄膜電晶體單元之線路區域沒有設置框膠,由於該第一方向上相鄰兩個薄膜電晶體單元之線路區域或中心區域相鄰設置,雷射從相鄰之線路區域或中心區域之間切過時,液晶面板之位於雷射切割道兩側之結構對稱分佈,從而均衡切割過程中液晶面板之內部應力,可避免偏斜裂紋之產生。 Compared with the prior art, the central region of the thin film transistor unit of the liquid crystal panel is formed with a ring-shaped sealant adhered to the color filter glass plate, and the line region of the thin film transistor unit is not provided with a sealant. A line region or a central region of two adjacent thin film transistor units in a direction is adjacently disposed, and when the laser is cut between adjacent line regions or central regions, the structure of the liquid crystal panel on both sides of the laser cutting channel is symmetrically distributed. In order to balance the internal stress of the liquid crystal panel during the cutting process, the occurrence of skew cracks can be avoided.
下面結合附圖對本發明作進一步之詳細說明。 The invention will be further described in detail below with reference to the accompanying drawings.
請參見圖2,本發明第一實施例提供之適用於高良率雷射切割之液晶面板20包括薄膜電晶體玻璃板21、彩色濾光片玻璃板22以及第一框膠23。該彩色濾光片玻璃板22位於薄膜電晶體玻璃板21之一側。該第一框膠23位於薄膜電晶體玻璃板21與彩色濾光片玻璃板22之間。 Referring to FIG. 2, a liquid crystal panel 20 suitable for high-rate laser cutting according to a first embodiment of the present invention includes a thin film transistor glass plate 21, a color filter glass plate 22, and a first sealant 23. The color filter glass plate 22 is located on one side of the thin film transistor glass plate 21. The first sealant 23 is located between the thin film transistor glass plate 21 and the color filter glass plate 22.
該薄膜電晶體玻璃板21包括複數個沿x軸方向及y軸方向呈陣列狀排布之薄膜電晶體單元210。該複數個薄膜電晶體單元210相互間隔設置,且每個薄膜電晶體單元210都分別包括一個中心區域2102和一個位於該中心區域2102一側之線路區域2104。該中心區域2102之邊界處藉由第一框膠23與該彩色濾光片玻璃板22相黏接。通常,該第 一框膠23為環形。圖2所示y軸方向上任意兩相鄰薄膜電晶體單元210中,其中一個薄膜電晶體單元210之線路區域2104與另一個薄膜電晶體單元210之線路區域2104相鄰設置,或者其中一個薄膜電晶體單元210之中心區域2102與另一個薄膜電晶體單元210之線路區域2104相鄰設置。 The thin film transistor glass plate 21 includes a plurality of thin film transistor units 210 arranged in an array in the x-axis direction and the y-axis direction. The plurality of thin film transistor units 210 are spaced apart from each other, and each of the thin film transistor units 210 includes a central area 2102 and a line area 2104 on the side of the central area 2102, respectively. The center of the central region 2102 is bonded to the color filter glass plate 22 by the first sealant 23. Usually, the first A frame glue 23 is annular. In any two adjacent thin film transistor units 210 in the y-axis direction shown in FIG. 2, one of the line regions 2104 of the thin film transistor unit 210 is disposed adjacent to the line region 2104 of the other thin film transistor unit 210, or one of the films The central area 2102 of the transistor unit 210 is disposed adjacent to the line area 2104 of the other thin film transistor unit 210.
當雷射沿x軸方向切過相鄰之線路區域2104之間之區域或者相鄰之中心區域2102之間之區域時,切割道兩側均為線路區域2104或者均為中心區域2102,這種結構之對稱分佈可均衡切割過程中液晶面板之內部應力,從而可避免偏斜裂紋之產生,進而提高液晶面板雷射切割製程之良率。 When the laser cuts the area between adjacent line areas 2104 or the area between adjacent central areas 2102 along the x-axis direction, both sides of the scribe line are line areas 2104 or both are central areas 2102. The symmetrical distribution of the structure can balance the internal stress of the liquid crystal panel during the cutting process, thereby avoiding the occurrence of skew cracks, thereby improving the yield of the liquid crystal panel laser cutting process.
參見圖3,本發明第二實施例還提供一種適用於高良率雷射切割之液晶面板30,該液晶面板30之結構與上述液晶面板20之結構大體相同,不同之處在於,該液晶面板30之兩相鄰之線路區域3104之間還設置有第二框膠33。該第二框膠33可為環形或條形等。本實施例中,該第二框膠33為環形,且該第二框膠33之分別與沿線路區域3104之間間隔區域之邊界及彩色濾光片玻璃板32相黏接。該種設計可進一步加強線路區域3104之間間隔區域之結構強度,從而於切割過程中均衡液晶面板30之內部應力。 Referring to FIG. 3, a second embodiment of the present invention further provides a liquid crystal panel 30 suitable for high-rate laser cutting. The structure of the liquid crystal panel 30 is substantially the same as that of the liquid crystal panel 20, except that the liquid crystal panel 30 is A second sealant 33 is also disposed between the two adjacent line regions 3104. The second sealant 33 may be annular or strip-shaped or the like. In this embodiment, the second sealant 33 is annular, and the second sealant 33 is bonded to the boundary of the spaced region between the line region 3104 and the color filter glass plate 32, respectively. This design further enhances the structural strength of the spaced regions between the line regions 3104 to equalize the internal stress of the liquid crystal panel 30 during the cutting process.
參見圖4,本發明第三實施例還提供一種適用於高良率雷射切割之液晶面板40,該液晶面板40之結構與上述液晶面板20之結構大體相同,不同之處在於,該液晶面板40之薄膜電晶體玻璃板41之邊界區域藉由第三框膠44與彩 色濾光片玻璃板42相黏接。當雷射於y軸方向上沿虛線45切去液晶面板40多餘之邊界部分時,同樣由於切割道兩側第一、第三框膠43、44對液晶面板40結構強度之均衡,其可避免產生偏向液晶面板40邊緣之裂紋,從而保證良率。該第三框膠44可為環形或條形等。本實施例中,該第三框膠44為環形。 Referring to FIG. 4, a third embodiment of the present invention further provides a liquid crystal panel 40 suitable for high-rate laser cutting.

When the laser cuts off the excess boundary portion of the liquid crystal panel 40 along the broken line 45 in the y-axis direction, the first and third sealants 43, 44 on both sides of the scribe line balance the structural strength of the liquid crystal panel 40, which can be avoided. Cracks are generated which are biased toward the edges of the liquid crystal panel 40, thereby ensuring yield. The third sealant 44 may be annular or strip-shaped or the like. In this embodiment, the third sealant 44 is annular.
