此外，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本公开的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在本公开的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本公开中的具体含义。
如图1所示，本公开的一些实施例提供一种电子设备，该电子设备101可以为电视、手机、电脑、笔记本电脑、平板电脑、个人数字助理(英文：Personal Digital Assistant，简称PDA)、车载电脑等。
该电子设备101包括显示面板。该显示面板可以为液晶显示面板(Liquid Crystal Display，简称LCD)；该显示面板也可以为电致发光显示面板或光致发光显示面板。在该显示面板为电致发光显示面板的情况下，电致发光显示面板可以为有机电致发光(Organic Light-Emitting Diode，简称OLED)显示面板或量子点电致发光(Quantum Dot Light Emitting Diode，简称QLED)显示面板。在该显示面板为光致发光显示面板的情况下，光致发光显示装置可以为量子点光致发光显示装置。
该显示面板包括柔性显示屏102和成型模103，为了得到曲面的电子设备，通常将显示面板的柔性显示屏102设置为曲面贴合，例如，将成型模103的边缘加工为曲面，在柔性显示屏102与成型模103的贴合工艺中，使柔性显示屏102的边缘弯曲贴合于成型模103。
如图1所示，该柔性显示屏102包括主显示部1和边缘显示部2，边缘显示部2围绕主显示部1的边缘设置，且与主显示部1固定连接或一体成型。如图2所示，边缘显示部2朝向成型模103弯曲并与成型模103贴合。
在可选地实施例中，主显示部1可以位于同一个平面内，即主显示部1为平面结构，当然，主显示部1还可以为弧形显示部，即主显示部1的相对的两端的高度略低于中间部分的高度。主显示部1包括相邻的第一边11和第二边12，第一边11和第二边12通过弧线13连接，可以使得主显示部1的外轮廓更加圆滑。
如图2所示，该边缘显示部2包括第一弯折部21、第二弯折部22和角落弯折部23，第一弯折部21、角落弯折部23和第二弯折部22依次连接。第一弯折部21位于主显示部1的第一边11的一侧，且与第一边11连接；第二弯折部22位于主显示部1的第二边12的一侧，且与第二边12连接；角落弯折部23位于主显示部1的弧边13的一侧，且与弧边13连接。
在一些实施例中，第一弯折部21的侧边与第一边11连接，当其与成型模103贴合后，第一弯折部21可以与主显示部1之间互成角度；第二弯折部22的侧边与第二边12连接，当其与成型模103贴合后，第二弯折部22可以与主显示部1之间互成角度；角落弯折部23的侧边与弧边13连接，当其与成型模103贴合后，角落弯折部23可以与主显示部1之间互成角度。
其中，柔性显示屏102与成型模103贴合后，第一弯折部21、第二弯折部22和角落弯折部23的弯折方向相同。第一弯折部21、角落弯折部23和第二弯折部22依次连接并与主显示部1共同构成显示区，边缘弯折的柔性显示屏102显示面积较大，边缘线条更加流畅。
在一些实施例中，第一边11和第二边12均为直边，由此可以简化柔性显示屏102的结构，且便于柔性显示屏102和成型模103的贴合。
在一些实施例中，主显示部11包括多个边，任意相邻的两边均通过一条弧边13连接，每个弧边13上均连接有角落弯折部23，且多个角落弯折部23和第一弯折部21、第二弯折部22依次连接并与主显示部11共同构成柔性显示屏102的显示区，即角落弯折部23、第一弯折部21和第二弯折部22均设 置有像素，从而均可以实现显示功能。
柔性显示屏102和成型模103在柔性显示屏102的贴合工艺中，成型模103的角落位置一般类似球面，柔性显示屏102在角落位置的中间部位承受较大的径向(弧边13的径向，如图3所示的Y方向)和横向(弧边13的延伸方向，如图3所示的X方向)拉应力，因此，在角落弯折部23的中间部位会产生比第一弯折部21和第二弯折部22更大的拉应力，更容易产生裂纹、褶皱或造成贴合开裂，导致屏幕损坏。
如图3所示，在一些实施例中，角落弯折部设有多个开口4，多个开口4朝向角落弯折部的可弯折方向。在角落弯折部23的弯折工艺中，通过开口4的变形吸收角落弯折部23受到的部分拉应力，降低角落弯折部23开裂、褶皱的风险。
如图3所示，在示例性实施例中，该角落弯折部23包括走线区231和变形区232，可选地，变形区232靠近主显示部1并与主显示部1连接，走线区231位于变形区232远离主显示部1的一侧。
走线区用于布置一些元器件、像素电路和信号线中的一种或多种。
示例性地，如图3所示，走线区布置有第一信号线M1。
可选地，走线区231设置有至少一条第一信号线M1。
可选地，第一信号线M1例如可以是用于向像素传输灰阶数据信号的数据线、电源电压信号线等等。
在一些实施例中，变形区232设置有多个开口4，通过开口4的变形吸收角落弯折部23受到的部分拉应力，在降低角落弯折部23的开裂、褶皱风险的同时，降低走线区231的受力强度，从而保护了走线区231的元器件和像素电路等结构。
可以理解的是，走线区231未设置开口4，提高了走线区231的强度，使其相对于变形区232不容易变形，从而使走线区231的信号线得到保护，降低开裂风险。
在一些实施例中，相邻的开口4之间设有至少一个亚像素5，同时，相邻的开口4之间的间隙可以用于布置信号线，以实现显示功能。
可选地，可以根据相邻两个亚像素5之间的距离合理分布开口4的数量。
在可选的实施例中，角落弯折部23还包括多条第二信号线M2。
在可选的实施例中，当角落弯折部23包括走线区231和变形区232的情况下，第二信号线M2设置于变形区232。
可选地，每个亚像素5与至少一条第二信号线M2电连接。
可选地，多条第二信号线M2在多个开口4之间的间隙延伸，且每条第二信号线M2与一条第一信号线M1电连接。
可选的，第二信号线M2可与至少一个亚像素5电连接，第二信号线M2例如可以是用于向像素传输灰阶数据信号的数据线、电源电压信号线等等。
可选的，经过相邻两行开口4之间的第二信号线M2可以设置成折线或曲线，增强可拉伸性。
在一些实施例中，如图3所示，多个开口4在弧边13的径向(Y方向)上排列成多排，每排的多个开口4沿弧边13的延伸方向(X方向)间隔排列。由此在成型模103和柔性显示屏102贴合时，可以更好的吸收应力和应变，更好的改善柔性显示屏102贴合开裂的问题，同时可以更好的保护未设置开口4区域的发光器件和像素电路等。
在示例性实施例中，如图4所示，从变形区232的中心至第一弯折部21及第二弯折部22的两个方向(即X1方向和X2方向)，至少一排的多个开口4在弧边13的径向(即Y方向)上的尺寸逐渐变小。角落弯折部23在弯折贴合于成型模103后，一排开口4所在位置的中心区域较之两端区域受力大，因此从中心区域至两端区域，该排开口4在弧边13的径向上的尺寸逐渐减小，使得该排开口4所在位置的中心处吸收更多的应力，从而实现贴合后该排开口4所在位置在弧边13的径向上受力均匀的效果。
在示例性实施例中，如图5所示，从变形区232的中心至第一弯折部21及第二弯折部22的两个方向(即X1方向和X2方向)，至少一排的多个开口4在弧边13的延伸方向(即X1方向和X2方向)上的尺寸逐渐变小。从中心位置至边缘位置，该排开口4在弧边13的延伸方向上的尺寸逐渐减小，使得该排开口4所在位置的中心处吸收更多的应力，从而实现贴合后该排开口4所在位置在弧边13的延伸方向上受力均匀的效果。
在示例性实施例中，如图6所示，从变形区232的中心至第一弯折部21及第二弯折部22的两个方向(即X1方向和X2方向)，至少一排的多个开口4在弧边13的径向(即Y方向)上的尺寸逐渐变小，且在弧边13的延伸方向(即X1方向和X2方向)上的尺寸逐渐变小。通过同时在弧边13的径向和弧边13的延伸方向两个方向上设计开口4的尺寸，使其尺寸大小适应于角落弯折部23的受力大小，也即，受力较大的中心区域开口4尺寸大，吸收的应力多，受力较小的两端区域开口4尺寸小，吸收的应力少，从而使得贴合后该排开口4所在位置在弧边13的径向和弧边13的延伸方向者两个方向 上均受力均匀，从而有效降低角落弯折部23损坏的风险。
在示例性实施例中，如图7所示，从变形区232的中心至变形区232在弧边13的径向上的两侧边界(即分别从中心开始沿着Y1方向和Y2方向延伸)，多个开口4在弧边13的径向(即Y1方向和Y2方向)上的尺寸逐渐变小。角落弯折部23在弯折贴合于成型模103后，多个开口4所在的位置的中心区域较之两端区域受力大，因此从中心区域至两端区域，多个开口4在弧边13的径向上的尺寸逐渐减小，使得多个开口4所在位置的中心处吸收更多的应力，从而实现贴合后多个开口4所在位置在弧边13的径向上受力均匀的效果。
在示例性实施例中，如图8所示，从变形区232的中心至变形区232在弧边13的径向上的两侧边界(即分别从中心开始沿着Y1方向和Y2方向延伸)，多个开口4在弧边13的延伸方向(即X方向)上的尺寸逐渐变小。从中心位置至边缘位置，多个开口4在弧边13的延伸方向上的尺寸逐渐减小，使得多个开口4所在位置的中心处吸收更多的应力，从而实现贴合后多个开口4所在位置在弧边13的延伸方向上受力均匀的效果。
在示例性实施例中，如图9所示，从变形区232的中心至第一弯折部21及第二弯折部22的两个方向(即X1方向和X2方向)，多个开口4在弧边13的径向上的尺寸逐渐变小，且在弧边13的延伸方向上的尺寸逐渐变小。通过同时在弧边13的径向和弧边13的延伸方向两个方向上设计开口4的尺寸，使其尺寸大小适应于角落弯折部23的受力大小，也即，受力较大的中心区域开口4尺寸大，吸收的应力多，受力较小的两端区域开口4尺寸小，吸收的应力少，从而使得贴合后该列开口4所在位置在弧边13的径向和弧边13的延伸方向者两个方向上均受力均匀，从而有效降低角落弯折部23损坏的风险。
在示例性实施例中，如图232310所示，从变形区232的中心至第一弯折部21、第二弯折部22以及变形区232在弧边13的径向上的两侧边界的四个方向上(即X1方向、X2方向、Y1方向和Y2方向)，每排开口4在所述弧边13的延伸方向上的尺寸逐渐变小，且在弧边13的径向上的尺寸逐渐变小；同时，沿弧边的径向，多个开口4在所述弧边13的延伸方向上的尺寸逐渐变小，且在弧边13的径向上的尺寸逐渐变小。从而实现角落弯折部23贴合后在排方向和列方向上都处于受力均匀的状态。
在示例性实施例中，如图11所示，变形区232包括中间区域233和边缘区域234，边缘区域234环绕中间区域233设置。
在可选的实施例中，中间区域233内的开口4在弧边13的径向(如图11 中的Y方向)上的尺寸大于边缘区域234内的开口4在弧边13的径向上的尺寸。角落弯折部23在弯折贴合于成型模103后，中间区域233较之边缘区域234受力大，因此中间区域233较之边缘区域234开口4的尺寸大，使得中间区域233吸收更多的应力，从而实现贴合后中间区域233和边缘区域234在弧边13的径向上受力均匀的效果。
在可选的实施例中，中间区域233内的开口4在弧边13的延伸方向(如图11中的X方向)上的尺寸大于边缘区域234内的开口4在弧边13的延伸方向上的尺寸。从而实现贴合后中间区域233和边缘区域234在弧边13的延伸方向上受力均匀的效果。
在可选的实施例中，中间区域233内的开口4在弧边13的径向(如图11中的Y方向)上的尺寸和在弧边13的延伸方向上的尺寸均大于边缘区域234。从而实现贴合后中间区域233和边缘区域234在弧边13的径向和在弧边13的延伸方向上都实现受力均匀。
在可选的实施例中，中间区域233的多个开口4在弧边13的径向(如图11中的Y方向)上的尺寸大致相同。由此可以简化角落弯折部23的结构，从而简化柔性显示屏102的结构，可以提高柔性显示屏102的生产效率。
在可选的实施例中，边缘区域234的多个开口4在弧边13的径向(如图11中的Y方向)上的尺寸大致相同。由此可以简化角落弯折部23的结构，从而简化柔性显示屏102的结构，可以提高柔性显示屏102的生产效率。
在可选的实施例中，中间区域233的多个开口4在弧边13的延伸方向(如图11中的X方向)上的尺寸大致相同。由此可以简化角落弯折部23的结构，从而简化柔性显示屏102的结构，可以提高柔性显示屏102的生产效率。
在可选的实施例中，边缘区域234的多个开口4在弧边13的延伸方向(如图11中的X方向)上的尺寸大致相同。由此可以简化角落弯折部23的结构，从而简化柔性显示屏102的结构，可以提高柔性显示屏102的生产效率。
在可选的实施例中，中间区域233的多个开口4在弧边13的径向(如图11中的Y方向)和在弧边13的延伸方向(如图11中的X方向)上的尺寸均大致相同，且边缘区域234的多个开口4在弧边13的径向和在弧边13的延伸方向上的尺寸均大致相同。由此可以简化角落弯折部23的结构，从而简化柔性显示屏102的结构，可以提高柔性显示屏102的生产效率。
在示例性实施例中，如图11所示，变形区232沿弧边13的径向(Y方向)的尺寸为L1，沿弧边13的径向，中间区域233的边界与变形区232的边界的最小距离d1为
Figure PCTCN2021099220-appb-000003
例如，最小距离d1为0.25L1、0.26L1、0.275L1、 0.3L1或者0.33L1。
在示例性实施例中，如图11所示，变形区232沿弧边13的延伸方向(X方向)的尺寸为L2，沿弧边13的延伸方向，中间区域233的边界与变形区232的边界之间的最小距离d2为：
Figure PCTCN2021099220-appb-000004
例如，最小距离d2为0.166L2、0.17L2、0.175L2、0.18L2或者0.2L2。
需要说明的是，在图11中，L2和d2并非直线长度，L2是一排开口4的总弧长，d2为该排开口4中，中间区域233的边界与变形区232的边界之间的弧长。
在示例性实施例中，如图12所示，从变形区232的中心至第一弯折部21及第二弯折部22的两个方向(即X1方向和X2方向)，至少一排的多个开口4中相邻两个开口4之间的距离逐渐增大。
在示例性实施例中，如图13所示，从变形区232的中心至变形区232在弧边13的径向上的两侧边界(即从中心开始沿着Y1方向和Y2方向延伸)，多个开口4中相邻两个开口4之间的距离逐渐增大。
在可选的实施例中，从变形区232的中心至第一弯折部21及第二弯折部22的两个方向，至少一排的多个开口4中相邻两个开口4之间的距离逐渐增大，同时，从变形区232的中心至变形区232在弧边13的径向上的两侧边界，多个开口4中相邻两个开口4之间的距离逐渐增大。从变形区232的中心至角落弯折部23的四个侧边，角落弯折部23的受力逐渐减小，因此，从变形区232的中心至角落弯折部23的四个侧边，开口4的布置密度逐渐较小，从而实现角落弯折部23整体受力均匀的效果。
在示例性实施例中，如图14所示，多个开口4分为多组，多组开口4在弧边13的径向(即为Y方向)上排列成多排，每组的多个开口4沿弧边13的延伸方向(即为X方向)或弧边13的切线方向间隔布置；每组的多个开口4中相邻两个开口4之间的间距小于相邻两组开口4中距离最近的两个开口4之间的间距。由此可以增加开口4结构的多样性，有利于提高柔性显示屏102的结构强度。
在可选地实施例中，位于中间区域233的组成每组开口4的的开口4个数大于边缘区域234的组成每组开口4的开口4个数。
在示例性实施例中，如图15所示，开口4为沿柔性显示屏102的厚度方向贯穿角落弯折部23的通孔。呈通孔状设置的开口4能够吸收更多的应力，从而更大程度上保证角落弯折部23受力均匀。
在示例性实施例中，如图16所示，开口4为沿柔性显示屏102的厚度方 向凹陷的凹槽。可选地，凹槽的槽口朝向角落弯折部23的弯折方向。凹槽状的开口4可以在吸收应力的前提下，保证结构强度。
在示例性实施例中，如图17所示，开口4的形状可以为圆形(参照图14)、椭圆形(参照图17中的(Ⅵ))或多边形(参照图17中的(Ⅰ)、(Ⅱ)、(Ⅲ)、(Ⅴ))中的一种或多种。由此可以增加开口4结构的多样性。例如，开口4为六边形(参照图17中的(Ⅰ))，且中间宽度窄，两端宽度宽。例如，开口4为梯形(参照图17中的(Ⅱ))。
在可选地实施例中，多个开口4的形状相同。由此可以简化角落弯折部23的结构，从而简化柔性显示屏102的结构。例如，每个开口4均为圆形，或者每个开口4均为矩形。
如图18所示，本公开实施例提供一种装配上述柔性显示屏102的方法。
在一些实施例中，如图21所示，柔性显示屏102的装配方法包括S1～S3。
S1：分别在第一弯折部21、第二弯折部22和角落弯折部23远离主显示部1的侧边连接承载膜3；
S2：将柔性显示屏102贴合至成型模103上，承载膜的至少部分伸出所述成型模的边界；
S3：拉拽多个承载膜3以使柔性显示屏102与成型模103完全贴合。
通过上述装配方法，使得柔性显示屏102的边缘达到成型模103最佳的贴合位置，此时，角落弯折部23整体受力均匀，且角落弯折部23远离主显示部1的弧边13的边缘处于既不受力也不受压的状态，降低了角落边缘产生褶皱和分裂的风险。在柔性显示屏102的角落弯折部23包括变形区232和走线区231的情况下，可对走线区231形成有效的保护。
如图19所示，在未使用承载膜3进行拉拽装配时，柔性显示屏102的边缘只能达到虚线所指的位置，使用承载膜3进行装配后，较之虚线的位置，柔性显示屏102的边缘扩展了一圈。
图20为图19中沿FF’向的剖面图，其中，未使用承载膜3进行装配时(例如图20所示的弯折后状态1)，剖面线与柔性显示屏102的边界的交点为G点(如图19、图20所示)；使用承载膜3进行装配时(例如图20所示的弯折后状态2)，剖面线与柔性显示屏102的边界的交点为H点(如图19、图20所示)。剖面线与柔性显示屏102的主显示部1的边界的交点为N点(如图19、图20所示)。
如图20所示，Q为角落弯折部23没有弯折时(即未弯折状态)的外边缘位置。QN为角落弯折部23没有弯折时的长度，GN为角落弯折部23没有 通过承载膜3拉拽时弯折后的弧长，HN为角落弯折部23通过承载膜3拉拽后的弧长。R1为以N点所在边界W为轴线，沿该轴线的周向且过G点所形成的圆周的半径，R2为以N点所在边界W为轴线，沿该轴线的周向且过H点所形成的圆周的半径。
当没有使用承载膜3拉拽时，角落弯折部23贴合后的外边缘只能达到G点，此时，弧长GN等于长度QN，则角落弯折部23外边缘的圆周半径R1小于贴合前的角落弯折部23自然状态下的长度QN，因此，此时角落弯折部23的外边缘属于受压状态，容易产生褶皱。
而当使用承载膜3拉拽后，角落弯折部23贴合后的外边缘可以达到H点，此时，角落弯折部23外边缘的圆周半径R2等于贴合前角落弯折部23自然状态下的长度QN，因此，此时角落弯折部23的外边缘表现为既不受拉也不受压，降低了角落弯折部23外边缘产生褶皱和分裂的风险。
在一些实施例中，如图21所示，承载膜3远离主显示部1的侧边与夹子32连接，使得承载膜3受到均匀的拉拽力，实现对柔性显示屏102更为有效的拉拽。
在示例性实施例中，如图21所示，与角落弯折部23连接的承载膜3上设有多条间隔分布的缝隙31，多条缝隙31沿弧边13的延伸方向间隔开，每条缝隙31在弧边13的方向上延伸，且每条缝隙31的一端均延伸至承载膜3的与角落弯折部23连接的侧边。由此可以把与角落弯折部23连接的承载膜3分成许多份，每份承载膜3的受力独立，不受彼此影响，从而适应角落弯折部23不同位置不同的拉应力，从而使角落弯折部23贴合后各个位置受力平衡。
上述记载的柔性显示屏102在贴合完成后受力均匀，可以有效降低柔性显示屏102角落位置开裂、褶皱和破损的概率。
如图22所示，在未设置开口4时，柔性显示屏102角落弯折部23的中心区域较之四周区域受力较大，在贴合过程中，角落弯折部23容易褶皱，造成贴合不良，也容易因为受力不均匀而导致开裂，在使用过程中，受力较大的中心区域受到磕碰后极易破损。
如图23所示，在设置开口4后，柔性显示屏102角落弯折部23的整体受力较小且受力均匀，从而有效避免角落弯折部23的损坏。
其中，图22和图23中颜色较浅的区域表示受力较大，颜色较深的区域表示受力较小。
另一方面，如图1所示，本公开实施例提供一种电子设备101，包括上述 柔性显示屏102。
其中，电子设备101可以是显示不论运动(例如，视频)还是固定(例如，静止图像)的且不论文字还是的图像的任何装置。更明确地说，预期所述实施例可实施在多种电子装置中或与多种电子装置关联，所述多种电子装置例如(但不限于)移动电话、无线装置、个人数据助理(PDA)、手持式或便携式计算机、GPS接收器/导航器、相机、MP4视频播放器、摄像机、游戏控制台、手表、时钟、计算器、电视监视器、平板显示器、计算机监视器、汽车显示器(例如，里程表显示器等)、导航仪、座舱控制器和/或显示器、相机视图的显示器(例如，车辆中后视相机的显示器)、电子相片、电子广告牌或指示牌、投影仪、建筑结构、包装和美学结构(例如，对于一件珠宝的图像的显示器)等。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
