在一些实施例中，折叠显示器为电致发光显示器，柔性显示面板2为电致发光显示面板。如图3所示，电致发光显示面板包括显示基板21以及用于封装显示基板21的封装层22。
在一些示例中，封装层22为封装薄膜。
在另一些示例中，封装层22为封装基板。
在一些示例中，如图3所示，电致发光显示面板具有多个亚像素区。显示基板21包括第一衬底210、以及设置在第一衬底210上的多个发光器件和多个像素驱动电路。通常的，每个像素驱动电路对应一个发光器件，且这两者设置于一个亚像素区中。每个像素驱动电路包括多个薄膜晶体管211。每个薄膜晶体管211包括有源层、源极、漏极、栅极及栅绝缘层，源极和漏极分别与有源层接触。每个发光器件包括阳极212、发光功能层213以及阴极214。每个发光器件的阳极212和对应的像素驱动电路的多个薄膜晶体管211中作为驱动晶体管的薄膜晶体管211的漏极电连接。
示例的，发光功能层213仅包括发光层。又示例的，发光功能层213除包括发光层外，还包括电子传输层(election transporting layer，简称ETL)、电子注入层(election injection layer，简称EIL)、空穴传输层(hole transporting layer，简称HTL)以及空穴注入层(hole injection layer，简称HIL)中的一层或多层。
在另一些示例中，显示基板21还包括像素界定层215，像素界定层215包括多个开口区，一个发光器件设置于一个开口区中。
在又一些示例中，如图3所示，显示基板21还包括设置在像素驱动电路和与该像素驱动电路对应的发光器件的阳极212之间的平坦层216。
在一些示例中，电致发光显示面板是顶发光型显示面板，在此情况下，发光器件的靠近第一衬底210的阳极212呈不透明，远离第一衬底210的阴极214呈透明或半透明。
在另一些示例中，电致发光显示面板是底发光型显示面板，在此情况下，发光器件的靠近第一衬底210的阳极212呈透明或半透明，远离第一衬底210的阴极214呈不透明。
在又一些示例中，电致发光显示面板为双面发光型显示面板，在此情况下，发光器件的靠近第一衬底210的阳极212和远离第一衬底210的阴极214均呈透明或半透明。
在另一些实施例中，折叠显示器为液晶显示器，柔性显示面板2为液晶显示面板。如图4所示，液晶显示面板包括相对设置的阵列基板23和对盒基板24、以及设置在阵列基板23和对盒基板24之间的液晶层25。
在一些示例中，阵列基板23包括第二衬底230、以及设置在第二衬底230上的薄膜晶体管211和像素电极231，像素电极231与薄膜晶体管211的漏极电连接。阵列基板23具有多个亚像素区。通常的，薄膜晶体管211和对应的像素电极231设置于一个亚像素区中。
在另一些示例中，阵列基板23还包括设置在第二衬底230上的公共电极232。
示例的，像素电极231和公共电极232设置在同一层，在此情况下，像素电极231和公共电极232均为包括多个条状子电极的梳齿结构。
又示例的，像素电极231和公共电极232设置在不同层，在此情况下，如图4所示，像素电极231和公共电极232之间设置有第一绝缘层233。在公共电极232设置于薄膜晶体管211和像素电极231之间的情况下，如图4所示，公共电极232与薄膜晶体管211之间还设置有第二绝缘层234。
在一些示例中，如图4所示，对盒基板24包括设置在第三衬底240上的彩色滤光层241，在此情况下，对盒基板24也可以称为彩膜基板(Color filter，简称CF)。其中，彩色滤光层241至少包括红色光阻单元、绿色光阻单元以及蓝色光阻单元，红色光阻单元、绿色光阻单元以及蓝色光阻单元分别与阵列基板23上的亚像素区一一正对。对盒基板24还包括设置在第三衬底240上的黑矩阵图案242，黑矩阵图案242被配置为将红色光阻单元、绿色光阻单元以及蓝色光阻单元间隔开。
在一些示例中，如图4所示，液晶显示面板还包括设置在对盒基板24远离液晶层25一侧的上偏光片26以及设置在阵列基板23远离液晶层25一侧的下偏光片27。
本公开一些实施例提供一种支撑板1，可用于上述的折叠显示器中，如图5和图6所示，支撑板1包括支撑板本体11和多个通孔10。支撑板本体11具有至少一个图案化区域03，多个通孔10设置于至少一个图案化区域03，且沿支撑板本体11的厚度方向贯穿该支撑板本体11。
在一些示例中，如图5所示，支撑板本体11具有一个图案化区域03；多 个通孔10设置于该图案化区域03内。
在另一些示例中，如图6A和图6B所示，支撑板本体11具有多个图案化区域03，多个通孔10设置于多个图案化区域03内，且多个图案化区域03内的通孔数量不完全相等。这里，“不完全相等”指的是部分图案化区域内的通孔数量相等，部分图案化区域内的通孔数量不相等；或者，每个图案化区域内的通孔数量均不相等。
本公开实施例对支撑板本体11所具有的图案化区域03的数量不做限制，对每个图案化区域03内的通孔数量也不做限制，其均可根据支撑板的弯折需要进行设置。例如，在支撑板的弯折度较大的位置处设置图案化区域，在图案化区域内根据弯折时所需释放的弯折应力的大小设置通孔的数量。
示例的，如图6A所示，支撑板本体11具有两个图案化区域03，多个通孔10设置于该两个图案化区域03内，且每个图案化区域03中的通孔数量相等。
又示例的，如图6B所示，支撑板本体11具有三个图案化区域03，多个通孔设置于该三个图案化区域03内。图6B所示的支撑板弯折后呈如图6C所示的水滴状，三个图案化区域03分别位于弯折度较大的3个位置，其中，位于弯折度最大的位置处的图案化区域内的通孔数量较多。
如图5、图6A和图6B所示，每个通孔10在垂直于该支撑板本体11的厚度方向的第一平面上的投影形状为条形。这样，支撑板1在图案化区域03内进行弯折时，多个条形的通孔10会随着支撑板1的弯折而发生变形，从而释放弯折应力，有效缓解支撑板1在进行弯折时所出现的应力集中的问题，显著提高支撑板1的弯折能力；在支撑板弯折后再展开时，该多个条形的通孔会恢复原有状态，从而提高支撑板1弯折后回复平整的能力，使支撑板1获得良好的弯折和展开效果。此外，在支撑件1应用于折叠显示器中的情况下，可以进一步提高折叠显示器的弯折能力，以及折叠显示器折叠再展开后的平整度以及弯折后回复平整的能力。当然，多个通孔10在垂直于支撑板本体11的厚度方向的第一平面上的投影形状也可以是其他形状，例如，圆形、椭圆形等其它规则或不规则的形状，本公开实施例对此不进行限定，只要该通孔能满足在支撑板1发生弯折时释放弯折应力即可。
在一些实施例中，支撑板1的材料为具有一定的韧性和刚性的材料，例如金属、玻璃、陶瓷或有机材料等。材料的韧性保证了支撑板1弯折后的回复能力以及支撑板1展开后的平整度，材料的刚性保证了支撑板1的支撑性能。
在一些示例中，支撑板1的材料为金属。金属具有相对高的杨氏模量、优异的加工性能、高的材料刚性以及韧性，可匹配折叠显示器的各种需求。
在一些实施例中，如图5、图6A和图6B所示，每个通孔10在第一平面上沿第一方向X延伸。也就是说，多个通孔10的延伸方向平行，且每个通孔10沿第一方向X的尺寸大于其沿第二方向Y上的尺寸。这里，如图5和图6A、图6B所示，例如支撑板本体11为矩形，且支撑板本体11的相对的两边的延伸方向与第一方向X平行。第二方向Y在第一平面上与第一方向X垂直。这样，在支撑板1沿平行于第一方向X的弯折线12弯折的情况下，每个通孔10沿第二方向Y发生变形，且变形程度最大，可最大程度的释放弯折应力，提高支撑板1的弯折能力以及弯折后回复平整的能力。
需要说明的是，弯折线12为一虚拟的线。
在一些实施例中，如图7A所示，多个通孔10中的每个通孔10在第一平面上的投影形状为矩形。
在另一些实施中，如图7B所示，多个通孔10中的每个通孔10在第一平面上的投影形状为圆角矩形。这里，圆角矩形指矩形的四个内角均为圆角。当然，圆角矩形也可以是矩形的部分内角为圆角。图7B以矩形的四个内角均为圆角为例进行示意。
在支撑板1弯折的情况下，如图7A所示，每个通孔10在第一平面上的投影形状为矩形，则弯折应力集中在两个直角边的交点处。如图7B所示，每个通孔10在第一平面上的投影形状为圆角矩形，则弯折应力集中在圆角矩形的圆弧与相邻两边的交点处。二者相比，在第一平面上的投影形状为圆角矩形的通孔10释放弯折应力的能力大于在第一平面上的投影形状为矩形的通孔10，使得支撑板1在弯折时更不容易发生断裂。
在又一些实施例中，多个通孔10中的每个通孔10在第一平面上的投影形状为由两个直线部分和两个曲线部分构成的封闭形状。其中，两个直线部分均沿第一方向X延伸，且一个直线部分的每端均与另一个直线部分的一端在第二方向Y上对齐；每个曲线部分均与所述两个直线部分的各自相互对齐的一端连接。
在一些示例中，每个曲线部分为半圆。即，如图5和图6所示，每个通孔10在第一平面上的投影形状为由两个直线部分和两个半圆构成的封闭形状。这样，在支撑板1弯折的情况下，弯折应力分散到每个半圆处，可更大程度的分散弯折应力，提高支撑板1的弯折能力，避免支撑板1在弯折时发生断裂现象。
在又一些实施例中，多个通孔10完全相同。这里，“完全相同”指每个通孔10在第一平面上的投影形状完全相同，且投影形状的面积相等，即每个通孔10在第一平面上的投影形状的尺寸相等。
示例的，如图5和图6所示，每个通孔10在第一平面上的投影形状均为由两个直线部分和两个半圆构成的封闭形状，且该封闭形状的面积完全相等，即，每个通孔10在第一平面上的投影形状中，两个直线部分的长度、间距均相等，且两个半圆的半径均相等。
又示例的，如图7B所示，每个通孔10在第一平面上的投影形状均为圆角矩形，且该圆角矩形的投影面积相等，即每个通孔10在第一平面上的投影形状的每个直角边的长度、宽度均相等。这样，在支撑板1弯折的情况下，弯折应力分散均匀，从而避免了弯折应力分布不均导致支撑板1断裂。
在又一些实施例中，多个通孔10不完全相同。这里，“不完全相同”指的是部分相同，部分不相同；或者，全部不相同。
在一些示例中，多个通孔10在第一平面上的投影形状不完全相同。示例的，部分通孔10在第一平面上的投影形状为矩形，部分通孔10在第一平面上的投影形状为圆角矩形，部分通孔10在第一平面上的投影形状为由两个直线部分和两个半圆构成的封闭形状。又示例的，多个通孔10中的每个通孔10在第一平面上的投影形状均不相同。
在另一些示例中，如图8所示，每个通孔10在第一平面上的投影形状完全相同，但投影形状的面积不完全相等，即，每个通孔10在第一平面上的投影形状的尺寸不完全相同。
在一些实施例中，如图5-图8所示，多个通孔10沿第二方向Y排列为多列通孔10，任意相邻两列通孔10间隔设置。图5-图8以每列通孔10包括沿第一方向X排布的多个通孔10为例进行示意。当然，每列通孔10或多列通孔10中的部分列通孔10也可以仅包括一个通孔10。本公开实施例对每列通孔10中沿第一方向X排布的通孔10的数量不做限定。
在一些示例中，在多列通孔10的任意相邻两列通孔10中，位于其中一列通孔10中除最两端的两个通孔10外，任一个通孔10均与位于另一列通孔10中的相邻两个通孔10在垂直于所述第二方向Y的第二平面上的投影重叠。示例的，如图6所示，第一通孔101与相邻列通孔10中的第二通孔102和第三通孔103在垂直于所述第二方向Y的第二平面上的投影重叠。
在另一些示例中，在多列通孔10的任意相邻两列通孔10中，位于其中一列通孔10中的最两端的两个通孔10中的每个通孔10与位于另一列通孔10 中的一个通孔10或相邻的两个通孔10在垂直于所述第二方向的第二平面上的投影重叠。示例的，如图6所示，位于中间列通孔10中的第四通孔104与相邻列通孔10中的第二通孔102在垂直于所述第二方向Y的第二平面上的投影重叠。又示例的，如图6所示，第二通孔102与相邻列通孔10中的第一通孔101和第四通孔104在垂直于所述第二方向Y的第二平面上的投影重叠。
如图9所示，在多列通孔10的任意相邻两列通孔10中，位于其中一列通孔10中的任一个通孔10均与位于另一列通孔10中的任一个通孔10在垂直于所述第二方向Y的第二平面上的投影不重叠。基于此，每列通孔10中的任意相邻两个通孔10之间的实体部分与相邻列通孔10中的相邻两个通孔10之间的实体部分在第二方向Y上是连续的，例如，图9中椭圆虚线圈13标示的部分。这样，在支撑板1沿弯折线12弯折的情况下，弯折应力的方向与第二方向Y平行，使得相邻两列通孔10之间的实体部分受到的应力较大，支撑板1容易断裂。
相比于图9所示的多列通孔10的排布方式，图5-图8所示的多列通孔10的排布方式，即，相邻两列通孔10中的多个通孔10沿第二方向Y交错排布，使得每列通孔10中的任意相邻两个通孔10之间的实体部分在第二方向Y上正对相邻列通孔10中的一个通孔，可避免上述问题，有效提高支撑板1的弯折能力。
在一些示例中，如图5-图7B所示，多列通孔10中的任意相邻两列通孔10中，其中一列通孔10中的任意两个通孔10之间的部分在第二平面上的投影位于另一列通孔10中一个通孔10在所述第二平面上的投影的中间。参考图12，对支撑板1进行建模，并利用软件分析支撑板1弯折后的应力分布云图。根据应力分布云图，可以获取多个通孔10沿第一方向X的长度中的最大值A max、同一列通孔10中每两个相邻通孔10沿第一方向X的第二间距中的最小值B min、其中一列通孔10中的任意一个通孔10与相邻列通孔10中的任意一个通孔10沿第二方向Y的第一间距中的最小值C min、多个通孔10沿所述第二方向的宽度中的最大值D max、支撑件本体11在图案化区域03内沿平行于第一方向X的弯折线12弯折的弯折半径R(如图10所示)、以及支撑板本体11的厚度t之间的关系。
这里，每个通孔10沿第一方向X的长度为该通孔10沿第一方向X的最大长度，最大值A max为多个最大长度中的最大值。同一列通孔10中每两个相邻通孔10沿第一方向X的第二间距为该两个通孔10沿第一方向X的最小第二间距，最小值B min为多个最小第二间距中的最小值。其中一列通孔10中的 任意一个通孔10与相邻列通孔10中的任意一个通孔10沿第二方向Y的第一间距为该两个通孔10沿所述第二方向的最小第一间距，最小值C min为多个最小第一间距中的最小值。每个通孔10沿第二方向Y的宽度为该通孔10沿所述第二方向Y的最大宽度，最大值D max为多个最大宽度中的最大值。
示例的，如图5-图6以及图11所示，每个通孔10在第一平面上的投影形状完全相同，面积相等，且均匀排布于图案化区域03内。则每个通孔10沿第一方向X的最大长度A相等，即A max等于A；每两个通孔10沿第一方向X的最小第二间距B相等，即B max等于B；其中一列通孔10中的任意一个通孔与相邻列通孔中的任意一个通孔10沿第二方向Y的最小第一间距C相等，即C max等于C；每个通孔10沿第二方向Y的最大宽度D相等，即D max等于D。
另示例的，如图13所示(图13为图8中P’处的局部放大示意图)，每个通孔10在第一平面上的投影形状完全相同，但面积不完全相同，即尺寸不完全相同。多个通孔10中的每个通孔10沿第一方向X的最大长度不完全相等，即，具有多个最大长度，则最大值A max即为多个最大长度中的最大值A’。多个通孔10中的同一列通孔10中，每两个相邻通孔10沿第一方向X的最小第二间距不完全相等，即，具有多个最小第二间距，则最小值B min为多个最小第二间距中的最小值B’。多个通孔10中的任意相邻两列通孔10中，其中一列通孔10中的任意一个通孔与相邻列通孔中的任意一个通孔10沿第二方向Y的最小第一间距不完全相等，即，具有多个最小第一间距，则最小值C min为多个最小第一间距中的最小值C’。多个通孔10中的每个通孔10沿所述第二方向Y的最大宽度相等，即D max等于D’。
一些实施例中，最大值A max、最小值C min与弯折半径R满足关系式：
Figure PCTCN2021072866-appb-000002
上述公式中的最大值A max、最小值C min和弯折半径R的单位相同。例如，均采用毫米(mm)。
这样，通过对多个通孔10的最大值A max和最小值C min设计，即对多个通孔10的形状以及多个通孔10在图案化区域03内的排布方式的设计，可使支撑板本体11匹配更小的弯折半径，提升支撑板1的弯折能力；以使其应用于折叠显示器时，提升折叠显示器的折叠效果。
在另一些实施例中，最大值A max、最小值C min与弯折半径R满足关系式：
Figure PCTCN2021072866-appb-000003
且最小值C min与支撑板本体11的厚度t满足：t:C min＝1～4。这样，在满足最小弯折半径的情况下，可最大程度的降低支撑板本体的厚度，以使 其应用于折叠显示器时，减小折叠显示器的厚度。
在又一些实施例中，最大值A max、最小值C min与弯折半径R满足关系式：
Figure PCTCN2021072866-appb-000004
最大值D max与最小值C min满足：D max:C min＝1～5。
在又一些实施例中，最大值A max、最小值C min与弯折半径R满足关系式：
Figure PCTCN2021072866-appb-000005
最小值C min与支撑板本体11的厚度t满足：t:C min＝1～4；且最大值D max与最小值C min满足：D max:C min＝1～5。
在又一些实施例中，最大值A max、最小值C min与弯折半径R满足关系式：
Figure PCTCN2021072866-appb-000006
最小值B min与最小值C min满足：B min:C min＝0.5～4。
在又一些实施例中，最大值A max、最小值C min与弯折半径R满足关系式：
Figure PCTCN2021072866-appb-000007
最小值C min与支撑板本体11的厚度t满足：t:C min＝1～4；最大值D max与最小值C min满足：D max:C min＝1～5；且最小值B min与最小值C min满足：B min:C min＝0.5～4。
在又一些实施例中，最大值A max、最小值C min与弯折半径R满足关系式：
Figure PCTCN2021072866-appb-000008
最大值A max与最小值B min满足：A max:B max＝10～100。
在又一些实施例中，最大值A max、最小值C min与弯折半径R满足关系式：
Figure PCTCN2021072866-appb-000009
最小值C min与支撑板本体11的厚度t满足：t:C min＝1～4；最大值D max与最小值C min满足：D max:C min＝1～5；最小值B min与最小值C min满足：B min:C min＝0.5～4；且最大值A max与最小值B min满足：A max:B max＝10～100。这样，根据不同的弯折半径R来设计图案化区域03内各通孔10的大小、各通孔10之间的间距以及支撑板1的厚度等参数，以确保在该弯折半径R下对支撑板1进行弯折时，支撑板1受到的最大应力小于支撑板1的材料的应力，即，确保支撑板1在沿弯折线12以该弯折半径R进行弯折时，支撑板1不会断裂，并使支撑板1以不同弯折程度弯折再展开后，均具有较强的弯折后的回复平整的能力。
在一些实施例中，参考图5-图9，在至少一列通孔10中的最两端的两个通孔10或其中一端的一个通孔10沿第一方向X的实际长度小于A max的情况下，该通孔10位于该列通孔10的一端的端部未封闭。也就是说，该通孔10使得支撑板本体11在沿第一方向X的端部形成缺口。
示例的，如图5所示，多个通孔10在图案化区域03内沿第二方向Y排列成5列通孔10。在第1列通孔10、第3列通孔10和第5列通孔10中，每列通孔10的最两端的两个通孔10的位于该列通孔10的一端的端部均未封闭。
又示例的，如图8所示，多个通孔10在图案化区域03内沿第二方向Y排列成5列通孔10。第1列通孔10的其中一端的一个通孔10的位于该列通孔10的一端的端部未封闭。第3列通孔10和第5列通孔10的最两端的两个通孔10的位于该列通孔10的一端的端部均未封闭。
在另一些实施例中，参考图16-图18，每列通孔10中的最两端的两个通孔10均为封闭的通孔。
示例的，如图16所示，多个通孔10在图案化区域03内沿第二方向Y排列成5列通孔10。每列通孔10中的最两端的两个通孔10均为封闭的通孔，且每个通孔10在第一平面上的投影形状完全相同，且投影形状的面积完全相等。
另示例的，如图17所示，多个通孔10在图案化区域03内沿第二方向Y排列成5列通孔10。每列通孔10中的最两端的两个通孔10均为封闭的通孔，且除每列通孔10的最两端的两个通孔10外，其它通孔10在第一平面上的投影形状完全相同，且投影形状的面积完全相等。每列通孔10的最两端的两个通孔10在第一平面上的投影形状完全相同，且投影形状的面积完全相等。
又示例的，如图18所示，多个通孔10在图案化区域03内沿第二方向Y排列成5列通孔10。每列通孔10中的最两端的两个通孔10均为封闭的通孔。并且，多个通孔10中的每个通孔10在第一平面上的投影形状完全相同，且投影形状的面积不完全相等。
在一些实施例中，每个通孔10沿所述第一方向X的最大长度的取值范围为1mm～50mm，支撑板1的厚度t的取值范围均为0.01mm～0.5mm。
例如，每个通孔10沿沿第一方向X的最大长度可以为1mm、2mm、5mm、8mm、10mm、15mm、20mm、25mm、30mm或50mm等。支撑板1的厚度t可以为0.01mm、0.05mm、0.1mm、0.2mm或0.5mm等。
以下提供了多种具体的实施例，详细说明上述各个参数的取值。各实施例均以图5所示的多个通孔10在第一平面上的投影形状以及在图案化区域03中的排布方式为例，即，每个通孔10在第一平面上的投影形状相同，且面积相等，并且每两个通孔10沿第一方向X的第二间距以及沿第二方向Y的第一间距均相等。
例如，每个通孔10沿第一方向X的最大长度A为4mm，同一列通孔10中每两个相邻通孔10沿第一方向X的最小第二间距B为0.2mm，一列通孔10中的任意一个通孔10与相邻列通孔10中的任意一个通孔10沿第二方向Y的最小第一间距C为0.2mm，每个通孔10沿第二方向Y的最大宽度D为 0.2mm，支撑板1的厚度t为0.2mm。又例如，每个通孔10沿第一方向X的最大长度A为6mm，同一列通孔10中每两个相邻通孔10沿第一方向X的最小间距B为0.1mm，一列通孔10中的任意一个通孔10与相邻列通孔10中的任意一个通孔10沿第二方向Y的最小第一间距C为0.1mm，每个通孔10沿第二方向Y的最大宽度D为0.3mm，支撑板1的厚度t为0.15mm。
又例如，每个通孔10沿第一方向X的最大长度A为9mm，同一列通孔10中每两个相邻通孔10沿第一方向X的最小间距B为0.1mm，一列通孔10中的任意一个通孔10与相邻列通孔10中的任意一个通孔10沿第二方向Y的最小第一间距C为0.1mm，每个通孔10沿第二方向Y的最大宽度D为0.1mm，支撑板1的厚度t为0.1mm。
例如，每个通孔10沿第一方向X的最大长度A为4mm，同一列通孔10中每两个相邻通孔10沿第一方向X的最小间距B为0.2mm，一列通孔10中的任意一个通孔10与相邻列通孔10中的任意一个通孔10沿第二方向Y的最小第一间距C为0.2mm，每个通孔10沿第二方向Y的最大宽度D为0.2mm，支撑板1的厚度t为0.2mm。根据公式

本公开一些实施例提供一种折叠显示器，如图14所示，折叠显示器包括上述任一实施例中的柔性显示面板2和上述任一实施例所述的支撑板1，支撑板1设置在柔性显示面板2的与出光侧相对的一侧。
如图14所示，柔性显示面板2具有弯折显示部01，通过对弯折显示部01进行弯折，可实现折叠显示器的折叠状态。示例的，柔性显示面板2具有一个弯折显示部01。又示例的，柔性显示面板2具有两个或两个以上弯折显示部01。本公开实施例对柔性显示面板2所具有的弯折显示部01的数量不进行限定，可以根据需要进行设置。附图14以柔性显示面板2具有一个弯折显示部01为例进行示意。
本公开实施例中，在柔性显示面板2的与出光侧相对的一侧设置支撑板1，一方面，支撑板1被配置为对柔性显示面板2进行支撑；另一方面，折叠显示器经过折叠再展开后，弯折显示部01会出现不平整的现象，支撑板1可以提升折叠显示器展开后的平整度以及弯折后回复平整的能力。
如图14和图15所示，柔性显示面板2的弯折显示部01在第一平面上的正投影与支撑板1的图案化区域03在第一平面上的正投影重叠。也就是说，在柔性显示面板2展开的状态下，在垂直于支撑板1厚度的方向上，柔性显示面板2的弯折显示部01正对支撑板1上至少一个图案化区域03中的部分通孔10。
这样，在柔性显示面板2的弯折显示部01弯折时，支撑板1随着弯折显示部01弯折，该部分通孔10会随着支撑板1的弯折而发生变形，从而释放弯折应力，提高支撑板1弯折后回复平整的能力，进而使得支撑板1除了具有对柔性显示面板2的支撑功能外，还可以提高折叠显示器折叠再展开后的平整度以及弯折后回复平整的能力。此外，支撑板1的弯折能力还可以提高柔性显示面板2的弯折能力，以提高折叠显示屏的折叠效果。
在一些示例中，如图14所示，柔性显示面板2还包括沿第二方向Y位于弯折显示部01两侧的非弯折显示部02。支撑板1具有一个图案化区域03， 该图案化区域03在第一平面上的正投影覆盖柔性显示面板2的弯折显示部01在第一平面上的正投影。也就是说，在柔性显示面板2展开的状态下，该图案化区域03沿第二方向Y的宽度大于等于该弯折显示部01沿第二方向Y的宽度。这样，在柔性显示面板2的弯折显示部01弯折时，支撑板1上的多个通孔可以对弯折显示部01的任意部分实现弯折应力释放，并能在柔性显示面板2再展开时，对弯折显示部01的任意部分实现回复平整，从而提高了折叠显示屏折叠再展开后的显示效果。此外，在图案化区域03沿第二方向Y的宽度大于该弯折显示部01沿第二方向Y的宽度的情况下，即图案化区域03中的部分通孔10还可以对弯折显示部01与非弯折显示部02的交界处进行弯折应力释放，以在柔性显示面板2弯折时，提高弯折显示部01与非弯折显示部02的交界处的平整度及回复平整的能力。
在另一些示例中，支撑板1具有两个图案化区域03，柔性显示面板2的弯折显示部01在第一平面上的正投影与每个图案化区域03在第一平面上的正投影具有重叠部分。如图15所示，该重叠部分分别位于弯折显示部01靠近非弯折显示部02的两侧。这样，在柔性显示面板2以较大的弯折半径弯折的情况下，弯折显示部01的中间部分近似未发生弯折，也就是说，该中间部分几乎不产生应力集中，因此，不需要通孔10对弯折应力进行释放。
在一些示例中，如图14和图15所示，每个通孔10在第一平面上沿第一方向X(即，垂直于纸面的方向)延伸，柔性显示面板2的弯折显示部01沿平行于第一方向X的弯折线弯折。这样，在柔性显示面板2弯折的情况下，每个通孔10沿第二方向Y发生变形，且变形程度最大，可最大程度的释放弯折应力，提高柔性显示面板2弯折后回复平整的能力，提升折叠显示器折叠再展开后的显示效果。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。
