Since in this embodiment, the first substrate 202 is convex, the aforementioned exhaust port 226a is located at the midpoint and at the highest point when the first substrate 202 is laid flat.

第5A圖與第5B圖繪示本發明第二實施例之框膠結構。第5A圖為於第一基板202上的框膠結構220的上視圖。框膠結構220圍繞於第一基板202的邊緣與展膠區210之間。框膠結構220可包含框膠體222及檔牆結構224。在本發明實施例中，框膠體222圍繞著展膠區210的四邊並具有一對缺口222a。檔牆結構224為一對條狀檔牆2241，位於前述框膠體222中的前述缺口222a的外側並且平行設置。由圖中所示，框膠體222和檔牆結構224並不相交。前述缺口222a設置於展膠區210之中心線（未顯示）上，且對應設置於展膠區210的相對兩側。又，前述缺口222a的寬度d大約介於2mm到10mm之間，於此寬度區間內的缺口222a足以使多餘的光學液態膠（未顯示）流出又可定義出具有緩衝功能的導流槽226。5A and 5B show the sealant structure of the second embodiment of the present invention. FIG. 5A is a top view of the sealant structure 220 on the first substrate 202. The sealant structure 220 surrounds the edge of the first substrate 202 and the spreading area 210. The frame rubber structure 220 may include a frame rubber body 222 and a barrier wall structure 224. In the embodiment of the present invention, the frame glue 222 surrounds the four sides of the glue spreading area 210 and has a pair of notches 222a. The barrier wall structure 224 is a pair of strip-shaped barrier walls 2241, which are located outside the aforementioned gap 222a in the aforementioned frame rubber body 222 and are arranged in parallel. As shown in the figure, the frame rubber body 222 and the retaining wall structure 224 do not intersect. The aforementioned notch 222 a is arranged on the center line (not shown) of the glue spreading area 210 and correspondingly arranged on opposite sides of the glue spreading area 210. In addition, the width d of the aforementioned notch 222a is approximately between 2 mm and 10 mm. The notch 222a in this width range is sufficient to allow excess optical liquid glue (not shown) to flow out and define a diversion groove 226 with a buffer function.

繼續參照第5A圖，第5B圖為第5A圖的沿A’-A’’線段的剖面示意圖。框膠體222和檔牆結構224之間定義出二導流槽226，位於框膠體222的外側，可延長排氣通道，亦作為溢膠的緩衝。又，在此實施例中，於導流槽226遠離缺口222a處定義出排氣口226a，此排氣口226a位於框膠結構220上的最高點，有助於氣泡的排出。由於在此實施例中，第一基板202可為凹面，因此，前述排氣口226a鄰近第一基板202的角落。Continuing to refer to Fig. 5A, Fig. 5B is a schematic cross-sectional view along the line A'-A’’ of Fig. 5A. Two diversion grooves 226 are defined between the frame rubber body 222 and the retaining wall structure 224, which are located on the outside of the frame rubber body 222, which can extend the exhaust passage and also serve as a buffer for overflowing rubber. Moreover, in this embodiment, an exhaust port 226a is defined at a location away from the notch 222a of the diversion groove 226, and the exhaust port 226a is located at the highest point on the sealant structure 220 to facilitate the discharge of air bubbles. Since in this embodiment, the first substrate 202 may be a concave surface, the aforementioned exhaust port 226 a is adjacent to the corner of the first substrate 202.

於第一基板202上設置完框膠結構220後，可進行第二基板204的對組，再由遠離排氣口226a處注入液態光學膠（LOCA）（未顯示），使得框膠結構內充滿液態光學膠（LOCA），進而使第一基板202和第二基板204貼合，最後再根據注入的液態光學膠（LOCA）之種類選擇封口膠（未顯示）設置於導流槽226內。例如，如注入的液態光學膠（LOCA）流動性較高，則使用框膠作為封口膠；若注入的液態光學膠（LOCA）流動性較低，則使用液態光學膠（LOCA）作為封口膠。After setting the sealant structure 220 on the first substrate 202, the second substrate 204 can be paired, and then liquid optical adhesive (LOCA) (not shown) is injected from a place away from the exhaust port 226a, so that the sealant structure is filled with Liquid optical adhesive (LOCA) is used to bond the first substrate 202 and the second substrate 204 together, and finally, a sealing adhesive (not shown) is selected according to the type of the injected liquid optical adhesive (LOCA) and placed in the diversion groove 226. For example, if the injected liquid optical adhesive (LOCA) has high fluidity, use sealant as the sealant; if the injected liquid optical adhesive (LOCA) has low fluidity, use the liquid optical adhesive (LOCA) as the sealant.

舉例而言，可參照第6A圖，使用第二實施例中（如第4圖所示）第一基板202上框膠結構222，將第一基板202和第二基板204對組後，從缺口222a的相對側灌注液態光學膠（LOCA）240。在此實施例中，液態光學膠（LOCA）240由缺口222a的遠端逐漸填滿展膠區210，直到過多的液態光學膠（LOCA）240被導入導流槽226朝缺口222a排出，如第6B圖所示。For example, referring to Fig. 6A, using the sealant structure 222 on the first substrate 202 in the second embodiment (as shown in Fig. 4), the first substrate 202 and the second substrate 204 are paired together, The opposite side of 222a is filled with liquid optical glue (LOCA) 240. In this embodiment, the liquid optical adhesive (LOCA) 240 gradually fills the spreading area 210 from the distal end of the notch 222a, until the excessive liquid optical adhesive (LOCA) 240 is introduced into the diversion groove 226 and discharged toward the notch 222a, as in the first As shown in Figure 6B.

另外，再回去參照第3A圖到第5A圖，框膠結構220中的導流槽226的寬度w大約介於1mm到5mm之間，小於1mm會使得導流槽的緩衝效果降低，容易於框膠結構外產生溢流，而大於5mm會使得展膠區210太小，使得接合面積下降。In addition, referring back to Figs. 3A to 5A, the width w of the diversion groove 226 in the sealant structure 220 is approximately between 1mm and 5mm, and less than 1mm will reduce the buffering effect of the diversion groove, which is easy to frame. Overflow is generated outside the glue structure, and if it is larger than 5 mm, the glue spreading area 210 will be too small, which will reduce the joint area.

在一些實施例中，第二基板204上可更設置油墨層（未顯示），使油墨層介於框膠結構220與第二基板204之間。上述油墨層可防止框膠結構220的暴露，亦不會對可視區造成影響。In some embodiments, an ink layer (not shown) may be further provided on the second substrate 204 so that the ink layer is between the sealant structure 220 and the second substrate 204. The above-mentioned ink layer can prevent the sealant structure 220 from being exposed, and will not affect the visible area.

如第7A圖和第7B圖所示，將第二實施例中（如第4圖所示），第一基板202設置框膠結構220和第二基板204設置油墨層230後，將第一基板202和第二基板204對組，使得框膠結構220和油墨層230介於第一基板202和第二基板204之間。第7A圖為於第二基板204的上視圖，由於第7A圖以第4A圖為基礎，更設置油墨層230，因此與第4A圖相同部分在此不多贅述。As shown in Figures 7A and 7B, in the second embodiment (as shown in Figure 4), the first substrate 202 is provided with a sealant structure 220 and the second substrate 204 is provided with an ink layer 230, then the first substrate 202 and the second substrate 204 are paired so that the sealant structure 220 and the ink layer 230 are interposed between the first substrate 202 and the second substrate 204. FIG. 7A is a top view of the second substrate 204. Since FIG. 7A is based on FIG. 4A and further includes an ink layer 230, the same parts as those in FIG. 4A will not be repeated here.

參照第7A圖，藉由油墨層230下方的部分透視圖，可看出油墨區230之下的框膠結構220，同第4A圖所示。位於框膠結構220之上的油墨層230，可完全覆蓋框膠結構220，但不影響可視區。位於展膠區210的液態光學膠（LOCA）240，將第一基板202和第二基板204貼合。由於在此實施例中，第一基板202和第二基板204分別為液晶顯示模組（LCM）和覆蓋玻璃（CG），因此上視圖仍可看到位於第二基板204下的配置情形。Referring to FIG. 7A, from the partial perspective view below the ink layer 230, it can be seen that the sealant structure 220 under the ink area 230 is the same as that shown in FIG. 4A. The ink layer 230 located on the sealant structure 220 can completely cover the sealant structure 220 without affecting the visible area. The liquid optical glue (LOCA) 240 located in the glue spreading area 210 bonds the first substrate 202 and the second substrate 204 together. Since in this embodiment, the first substrate 202 and the second substrate 204 are a liquid crystal display module (LCM) and a cover glass (CG), respectively, the configuration under the second substrate 204 can still be seen from the top view.

參照第7B圖，第7B圖為第7A圖的沿A’-A’’線段的剖面示意圖。在此實施例中，第一基板202和第二基板204皆為凸面，且框膠體222和油墨層230的高度大約相同，但不限於此。又，油墨層230的目的為遮蔽下方之框膠結構220，油墨層230之邊界可以剛好與框膠結構220之邊界相同，抑或是更向展膠區210延伸，以不影響可視區為前提。另外，由於框膠結構以第4A圖和4B圖作為基礎，注入液態光學膠（LOCA）240的過程同第6A圖和第6B圖所示，在此不多贅述。Referring to Fig. 7B, Fig. 7B is a schematic cross-sectional view of Fig. 7A along the line A’-A’’. In this embodiment, both the first substrate 202 and the second substrate 204 are convex surfaces, and the height of the frame compound 222 and the ink layer 230 are approximately the same, but it is not limited thereto. In addition, the purpose of the ink layer 230 is to shield the sealant structure 220 below, and the boundary of the ink layer 230 can be exactly the same as the boundary of the sealant structure 220, or it can extend to the spreading area 210, provided that the visible area is not affected. In addition, since the sealant structure is based on FIGS. 4A and 4B, the process of injecting the liquid optical adhesive (LOCA) 240 is the same as that shown in FIGS. 6A and 6B, and will not be repeated here.

本發明實施例中的框膠結構，包含具有缺口的框膠體以及於缺口的一側的檔牆結構，且框膠體與檔牆結構之間可以定義出導流槽，可延長排氣通道，亦作為溢膠的緩衝，其效果於3D裝置中更加明顯，更能提高貼合良率。The frame rubber structure in the embodiment of the present invention includes a frame rubber body with a gap and a barrier wall structure on one side of the gap, and a diversion groove can be defined between the frame rubber body and the barrier wall structure, which can extend the exhaust passage and also As a buffer for overflowing glue, its effect is more obvious in 3D devices, and it can improve the bonding yield.
