Description

折叠屏及显示装置
本公开要求在2020年6月24日提交中国专利局、申请号为202010591908.X、名称为“折叠屏及显示装置”的中国专利申请的优先权，其全部内容通过引用结合在本公开中。
技术领域
本公开的实施例涉及一种折叠屏及显示装置。
背景技术
在发明人已知的技术中，折叠手机模组厚度较薄，为了保证折叠性能，常选择不锈钢作为模组结构的支撑层。不锈钢自身散热性能较差，需要设置铜箔或者石墨片辅助散热。由于通常的石墨片不具备弯折性能，因此仅能够在非折叠区域(如显示区域)设置石墨片，而不能在折叠区域设置石墨片，因此，极大减少了石墨接触面积，导致屏幕的散热性能大打折扣。
发明内容
本公开的至少一个实施例提供了一种折叠屏，包括多个沿第一方向间隔设置的显示区域以及位于相邻的两个所述显示区域之间的折叠区域，所述折叠屏还包括层叠设置的支撑层和散热层，其中，所述支撑层为可弯折的，且设置在所述显示区域和所述折叠区域；以及所述散热层为可弯折的，且设置在所述显示区域和所述折叠区域，所述散热层对应于所述折叠区域的部分设置有通孔阵列。
在本公开的一个实施例中，所述通孔阵列包括沿所述第一方向间隔排列有多行通孔，所述多行通孔中的每行通孔包括沿第二方向排列的多个通孔，所述多个通孔中的每个通孔具有沿第一方向的第一长度并具有沿第二方向的第二长度，其中，所述第一方向垂直于所述第二方向。
在本公开的一个实施例中，相邻的两行中的所述通孔相互错位排列。
在本公开的一个实施例中，在相邻的两行通孔中，通过第一行中的通孔中心的沿第一方向延伸的线经过第二行中相邻两个通孔中心之间连线的中点。
在本公开的一个实施例中，所述第二长度为所述第一长度的10倍～20倍。
在本公开的一个实施例中，相邻两行通孔之间的间距为所述第一长度的0.5倍～1倍。
在本公开的一个实施例中，位于同一行中的相邻的两个所述通孔之间的间距为所述第一长度的1倍～1.5倍。
在本公开的一个实施例中，所述通孔为矩形，所述矩形的角为圆角。
在本公开的一个实施例中，所述支撑层由不锈钢制成；以及所述散热层由石墨烯制成。
在本公开的一个实施例中，所述折叠屏还包括：
缓冲层，设置在所述支撑层远离所述散热层的一侧；
粘接层，设置在所述支撑层与所述散热层之间；以及
保护层，设置在所述散热层远离所述支撑层的一侧。
在本公开的一个实施例中，所述缓冲层由泡棉制成。
在本公开的一个实施例中，所述折叠屏还包括：依次叠设在缓冲层上的柔性显示基板以及盖板。
在本公开的一个实施例中，所述折叠屏还包括设置在所述柔性显示基板和所述盖板之间的偏光片。
本公开的至少一个实施例提供了一种显示装置，所述显示装置包括上述折叠屏。
上述实施例的折叠屏以及显示装置，通过在显示区域和折叠区域均设置能够能弯折或者展开的散热层，能够大大地提升折叠屏的整体散热性能；进一步，通过在折叠区域的散热层开设呈阵列排列的通孔，能够有效保证整体模组的可折叠性，使整体结构具有优异的折叠性能。

本公开的至少一个实施例提供了一种折叠屏1。如图1所示，折叠屏1包括层叠设置的支撑层10和散热层11，支撑层10和散热层11均能弯折，所述散热层11在所述支撑层10上的投影位于所述支撑层10内。
折叠屏1沿第一方向L1包括两个间隔设置的显示区域A1、以及位于所述两个显示区域A1之间的折叠区域A2，其中，显示区域A1和折叠区域A2均设有支撑层10和散热层11，且位于折叠区域A2的散热层11开设有呈阵列排列的通孔111。这样，通过在显示区域A1和折叠区域A2均设置能够能弯折的散热层11，能够大大地提升折叠屏1的整体散热性能；进一步，通过在折叠区域A2的散热层11开设呈阵列排列的通孔111，能够有效保证整体结构的可折叠性，使整体结构具有优异的折叠性能。
需要说明的是，根据设计需要，折叠屏1沿第一方向L1包括的间隔设置的显示区域A1的数量也可以是三个、或者四个或者其他数量，相应的，沿第一方向L1相邻的两个显示区域A1之间的折叠区域A2的数量也随着显示区域A1的数量的变化调整。
如图2和图3所示，呈阵列排列的通孔111的具体排列方式：沿第一方向L1间隔排列有多行通孔111，每行通孔111沿垂直于第一方向L1的第二方向L2间隔排列有多个通孔111。相邻的两行中的通孔111相互错位排列，以分散所受到的应力。在本公开的一个实施例中，在相邻的第一行通孔111和第二行通孔111中，通过第一行中的通孔 111的中心的沿第一方向延伸的线经过第二行中相邻两个通孔111的中心之间连线的中点。
通孔111沿第一方向L1的长度为第一长度s1，通孔111沿第二方向L2的长度为第二长度s2。相邻行之间的间距为s3，在同一行中相邻通孔之间的距离为s4。通孔111可以为矩形、椭圆形、菱形、圆角矩形、正多边形等规则的形状，当然通孔111也可以为不规则的形状。在本公开的一个实施例中，通孔111为矩形，以便于加工；所述矩形的角为圆角，做圆角处理以防止应力集中。
不论通孔111具有何种形状，通孔111的第一长度s1为该形状沿第一方向L1的最大长度，通孔111的第二长度s2为该形状沿第二方向L2的最大长度。
在本公开的一些实施例中，通孔111的第二长度s2大于或等于所述第一长度s1的10倍。相邻的两行的通孔111之间的间距s3小于或等于所述第一长度s1。位于同一行中的相邻的两个通孔111之间的间距s4大于或等于所述第一长度s1。
在本公开的一些实施例中，通孔111的第二长度s2为所述第一长度s1的10倍～20倍。相邻的两行的通孔111之间的间距s3为所述第一长度s1的0.5倍～1倍。位于同一行中的相邻的两个通孔111之间的间距s4为所述第一长度s1的1倍～1.5倍。这样，通过设置通孔111的尺寸以及排列间距，能够使散热层11具有更好的折叠性能。
需要说明的是，为了更好的展示通孔111的结构，在图2、图3以及图4中仅展示了支撑层10以及散热层11，而不包括其上的其他层结构。
在本公开的一些实施例中，支撑层10的材料为不锈钢。散热层11的材料为石墨烯，石墨烯具有厚度小，以及极佳的散热性能。但不限于此，支撑层10的材料也可以是其他具有支撑作用，且能够弯折的材料；同样，散热层11的材料也可以是其他具有散热作用，且能够弯折的材料。
在本公开的一些实施例中，折叠屏1还包括：缓冲层12、粘接层13和保护层14。缓冲层12位于支撑层10远离散热层11的一侧。粘接层13位于支撑层10与散热层11之间。保护层14位于散热层11远离支撑层10的一侧。
在本公开的一些实施例中，如图5所示，折叠屏1还包括：依次叠设在缓冲层12上的柔性显示基板15以及盖板16。其中，柔性显示基板15和盖板16之间还设有偏光片17，且偏光片17通过胶层18与盖板16贴合；柔性显示基板15和缓冲层12之间还设有背膜19，背膜19使柔性显示基板15平整化。
缓冲层12具有一定的减震和缓冲作用，而且，所述缓冲层12还可以将位于其下方的层结构与其上方的柔性显示基板15贴合。缓冲层12的可以由泡棉制成。由于通常先将缓冲层12、支撑层10以及散热层11先组合在一起，而后通过缓冲层12再进行贴合，这样，在后期贴合过程中不会增加额外工序。
保护层14由聚对苯二甲酸乙二醇酯(Polyethylene terephthalate，PET)制成，保护层14配置为保护散热层11。
散热层11与支撑层10通过粘接层13贴合，粘接层13可以由光学胶。同样，胶层18可以为光学胶。
本公开的至少一个实施例还提供了一种显示装置，所述显示装置包括上述折叠屏1。
以上所述仅为本公开的示例实施例而已，并不用以限制本公开，凡在本公开的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本公开保护的范围之内。
