背景技术
随着显示技术的快速发展,电子产品美观化、轻薄化趋势逐渐显现,OLED(Organic Light-Emitting Diode,有机发光二极管)柔性显示屏曲面贴合也随之快速发展起来。在OLED柔性显示屏两边曲贴合工艺日渐成熟的同时,OLED柔性显示屏四边曲贴合也日渐受到面板厂商和手机厂商的青睐。但是,随着OLED柔性显示屏进入盖板拐角区深度的增加,OLED柔性显示屏的受力愈加复杂。由于OLED柔性显示屏中位于拐角区的部分所受到的拉应力和压应力无法释放,常规的OLED柔性显示屏容易在拐角区出现裂纹和褶皱,导致OLED柔性显示屏中位于拐角区的部分膜层出现剥离,从而导致OLED柔性显示屏封装失效以致水氧入侵导致OLED柔性显示屏功能受损。

请参阅图2、图3和图4,图2为图1所示电子设备中显示装置的结构示意图,图3为图2所示显示装置的正视图,图4为图3中A部分的第一种局部放大图。显示装置20可以包括显示区21和设置在显示区21周缘的非显示区(图中未标号)。其中,显示区21可以设置有显示单元和触控单元,用于显示文字和图像等内容以及接受用户的触控操作;非显示区可以不设置显示单元和触控单元,不用于显示画面和接受用户的触控操作。
显示区21可以包括平直部211、第一弯折部212和第二弯折部213,其中,第一弯折部212和第二弯折部213均设置在平直部211的边缘,第一弯折部212和第二弯折部213共同围设在平直部211的周缘。
平直部211为平面板状结构,平直部211可以作为显示装置20的主显示部。平直部211可以为有棱角的板状结构,比如矩形结构或圆角矩形结构;平 直部211也可以为无棱角的板状结构,比如圆形结构。第二弯折部213为曲面板状结构,第二弯折部213弯折连接于平直部211的侧边,第二弯折部213可以作为显示装置20的副显示部。第一弯折部212弯折连接于平直部211的拐角且连接于相邻两个第二弯折部213之间,第一弯折部212可以作为显示装置20的辅显示部。其中,第一弯折部212朝第一方向F1弯曲设置,且第一方向F1与第一弯折部212相对平直部211弯折的方向不同。具体地,第一弯折部212可以为球面结构,第一方向F1为该球面的切向方向、第一弯折部212相对平直部211弯折的方向为该球面的径向方向。
需要说明的是,第一弯折部212和第二弯折部213的个数随平直部211的形状不同而不同,其中,第一弯折部212的个数与平直部211的拐角数保持一致,第二弯折部213的个数与平直部211的侧边数保持一致。
当平直部211为矩形或圆角矩形结构时,平直部211具有四条侧边和四个拐角,则显示区21包括分别弯折连接于平直部211四个侧边的四个第二弯折部213和分别弯折连接于平直部211四个拐角并位于相邻两个第二弯折部213之间的四个第一弯折部212。当平直部211为三角形或圆角三角形结构时,平直部211具有三条侧边和三个拐角,则显示区21包括分别弯折连接于平直部211三个侧边的三个第二弯折部213和分别弯折连接于平直部211三个拐角并分别位于相邻两个第二弯折部213之间的三个第一弯折部212。当平直部211为圆形时,平直部211具有零条侧边和无数个拐角,则显示区21包括弯折连接于平直部211周缘的无数个第一弯折部212而不包括第二弯折部213。本申请实施例附图以平直部211为圆角矩形结构为例,但本申请实施例对平直部211的具体形状以及第一弯折部212和第二弯折部213的具体个数不作限制。
非显示区可以包括设置在第一弯折部212边缘的第一非显示区22和设置在第二弯折部213边缘的第二非显示区23。可以理解的是,第一非显示区22连接于相邻两个第二非显示区23之间,第一非显示区22的个数与第一弯折部212的个数和平直部211的拐角数保持一致、第二非显示区23的个数与第二弯折部213的个数和平直部211的侧边数保持一致。
第一非显示区22设置有多个相互间隔的第一单元集合221,相邻的两个第一单元集合221之间设置有一个第二单元集合222,第一单元集合221和第二单元集合222均沿第一方向F1并排设置。其中,一个第一单元集合221可 以包括一或多个第一单元2210,一个第二单元集合222可以包括一或多个第二单元2220。第一单元2210的尺寸与第二单元2220的尺寸相同,但第一单元2210的结构与第二单元2220的结构不同,第一单元2210设置有多个相互间隔的沟槽220。
需要说明的是,随着显示技术的快速发展,电子产品美观化、轻薄化趋势逐渐显现,OLED柔性显示屏曲面贴合也随之快速发展起来。在OLED柔性显示屏两边曲贴合工艺日渐成熟的同时,OLED柔性显示屏四边曲贴合也日渐受到面板厂商和手机厂商的青睐。但是,OLED柔性显示屏四边曲贴合有一个技术难点,就是拐角贴合。
随着OLED柔性显示屏进入盖板拐角区深度的增加,OLED柔性显示屏的受力愈加复杂。OLED柔性显示屏角落贴合后,OLED柔性显示屏位于拐角区的部分中,中间区域受到较大的径向和切向的拉应力,致使最大拉应力比长边和短边最大拉应力更大,容易产生裂纹;OLED柔性显示屏位于拐角区的部分中,边缘区域受到较大的切向的压应力,容易产生褶皱。裂纹和褶皱会导致OLED柔性显示屏位于拐角区的部分膜层出现剥离,从而导致OLED柔性显示屏封装失效以致水氧入侵,进而导致OLED柔性显示屏功能受损。
因此,在OLED柔性显示屏位于拐角区部分的非显示区设置相应的结构以释放OLED柔性显示屏位于拐角区的部分所受到的拉应力和压应力,可以有效避免OLED柔性显示屏位于拐角区的部分出现裂纹和褶皱以致封装失效。
请参阅图5和图6,图5为图4中一个第一单元的第一种结构示意图,图6为图4中一个第二单元的结构示意图。假设第一弯折部212相对平直部211弯折的方向为第二方向F2。第一单元2210包括沿第二方向F2依次邻接的第一区2211、第二区2212、第三区2213和第四区2214,其中,第四区2214与第一弯折部212相邻。第二单元2220包括沿第二方向F2依次邻接的第五区2225、第六区2226和第七区2227,其中,第七区2227与第一弯折部212相邻。
第一区2211用于设置第一封装结构和第一切割保证线,第五区2225用于设置第二封装结构和第二切割保证线,第一区2211沿第二方向F2的长度小于第五区2225沿第二方向F2的长度。第二区2212用于设置沟槽220。第三区2213用于设置第一阴极,第六区2226用于设置第二阴极,第三区2213沿第 二方向F2的长度小于第六区2226沿第二方向F2的长度。第四区2214用于设置驱动信号线,第七区2227用于设置驱动单元,且第四区2214的驱动信号线与第七区2227的驱动单元电性连接,第四区2214沿第二方向F2的长度小于第七区2227沿第二方向F2的长度。
可以理解为,为了腾出够大的第二区2212设置沟槽220:相比较于第二单元2220中用于设置封装结构和切割保证线的第五区2225,第一单元2210中将用于设置封装结构和切割保证线的第一区2211缩小了;相比较于第二单元2220中用于设置阴极的第六区2226,第一单元2210中将用于设置阴极的第三区2213缩小了;相比较于第二单元2220中用于设置驱动单元的第七区2227,第一单元2210中不仅将用于设置驱动单元的第四区2214缩小了,而且直接不设置驱动单元而是设置驱动信号线并电性连接至第二单元2220中第七区2227的驱动单元。
请参阅图7,图7为图3中A部分的第二种局部放大图。第一非显示区22还包括布线区223,布线区223的一部分设置在第四区2214与第一弯折部212之间、布线区223的另一部分设置在第七区2227与第一弯折部212之间。通过进一步缩小第一单元2210中用于设置驱动信号线的第四区2214和第二单元2220中用于设置驱动单元的第七区2227,在第一单元集合221及第二单元集合222与第一弯折部212之间空出布线区223,可以用于设置连接显示区21与非显示区的导线。
请继续参阅图5。第二区2212具有沿第一方向F1相对设置的第一边(图中未标号)与第二边(图中未标号)。沟槽220包括第一子沟槽2201、第二子沟槽2202和第三子沟槽2203,第一子沟槽2201、第二子沟槽2202和第三子沟槽2203均为波浪形长条状结构。其中,第一子沟槽2201设置于第一边与第二边之间,第二子沟槽2202的槽壁与第一边连接,第三子沟槽2203的槽壁与第二边连接,第二子沟槽2202与第三子沟槽2203沿第一方向F1相对设置,且第一子沟槽2201与第二子沟槽2202及第三子沟槽2203沿第二方向F2部分相对设置。
需要说明的是,第一子沟槽2201、第二子沟槽2202和第三子沟槽2203也可以均为直线形长条状结构,如图8所示,图8为图4中一个第一单元的第二种结构示意图。第一子沟槽2201、第二子沟槽2202和第三子沟槽2203还 可以是不同的形状,如图9所示,图9为图4中一个第一单元的第三种结构示意图。其中,第一子沟槽2201为椭圆形长条状结构、第二子沟槽2202和第三子沟槽2203为直线形长条状结构。
请参阅图10,图10为图4中一个第一单元的第四种结构示意图。沟槽220也可以仅包括第一子沟槽2201和第二子沟槽2202。其中,第一子沟槽2201的槽壁与第一边连接,第二子沟槽2202的槽壁与第二边连接,且第一子沟槽2201与第二子沟槽2202沿第二方向F2部分相对设置。本申请实施例对沟槽220的具体结构和具体形状不作限制。
下面从显示装置20的层叠结构的角度对沟槽220的结构进行说明。
请参阅图11,图11为图10所示第一单元沿P-P方向的剖视图。显示装置20具有相背设置的显示面201与非显示面202。其中,显示面201为显示装置20中用于与用户进行人机交互的一面,位于电子设备100外侧,在使用过程中对用户可见;非显示面202为显示装置20中不用于与用户进行人机交互的一面,位于电子设备100内侧,在使用过程中对用户不可见。显示装置20包括从非显示面202到显示面201的方向层叠设置的聚酰亚胺薄膜203、多个无机层204和薄膜封装层205。一个无机层204中位于第一单元2210的部分设置有多个相互间隔的第一通孔2040,薄膜封装层205中位于第一单元2210的部分设置有多个相互间隔的第二通孔2050,每一个第一通孔2040与相邻的无机层204中的一个第一通孔2040连通,每一个第二通孔2050与相邻的无机层204中的一个第一通孔2050连通,从而使得显示装置20中位于第一单元2210的部分存在多个相互间隔的贯穿多个无机层204和薄膜封装层205的通孔,以形成沟槽220。沟槽220的宽度自非显示面202至显示面201的方向逐渐递减,以使沟槽220沿P-P方向的横截面为梯形。可以理解的是,沟槽220沿P-P方向的横截面也可以为三角形。本申请实施例对沟槽220横截面的具体形状不作限制。
以上对本申请实施例提供的显示装置及电子设备进行了详细介绍。本文中应用了具体个例对本申请的原理及实施方式进行了阐述,以上实施例的说明只是用于帮助理解本申请。同时,对于本领域的技术人员,依据本申请的思想,在具体实施方式及应用范围上均会有改变之处,综上所述,本说明书内容不应理解为对本申请的限制。
