具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
在本公开的描述中，需要说明的是，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本公开和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本公开的限制。此外，术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性。
目前的柔性屏模组强化结构，主要是在屏幕背面增加整面钢片或者图案化的钢片结构，用以提升模组支撑性和弯折性能。但是整面钢片的设置，柔软度低，不易弯折，而图案化的钢片结构的设置，一般是在整面钢片上进行刻蚀以形成图案化结构，整体还是由刚性材料制成，是一体结构，柔性显示屏进行弯折时，图案化结构仍然是要承受弯折应力的，进而限制了柔性显示屏的弯折性 能。
针对上述技术问题，参考图1-图6，本公开实施例提供一种柔性显示屏支撑结构，用于支撑柔性显示屏，所述柔性显示屏10包括沿第一方向间隔设置的可弯折区和非弯折区，包括：柔性支撑层3，所述柔性支撑层3包括相对设置的第一表面和第二表面，所述第一表面用于连接于所述柔性显示屏10的非出光侧，所述第二表面沿所述第一方向(参考图1中的X方向)划分为间隔设置的第一区域和第二区域，所述第一区域上设置有刚性支撑平板1，所述第二区域上间隔设置有多个相互平行的刚性支撑条2，多个所述刚性支撑条2沿着与所述第一方向相垂直的方向延伸设置，所述柔性支撑层3连接于柔性显示屏10的非出光光侧时，所述第一区域在所述柔性显示屏上的正投影与所述非弯折区重合，所述第二区域在所述柔性显示屏上的正投影与所述可弯折区重合。
通过所述柔性支撑层3将对应于柔性显示屏10的所述刚性支撑平板1和对应于柔性显示屏10的可弯折区的所述刚性支撑条2连接在一起，间隔设置的多个所述刚性支撑条2与柔性支撑层3相配合，既保证了柔性显示屏10的可弯折区的支撑性能，又保证了柔性显示屏10的可弯折区的弯折性能。
且相对于图案化设置的钢片结构，本实施例中，多个所述刚性支撑条2是间隔设置的，且是相互独立设置的，任意两个所述刚性支撑条2之间是没有连接的，多个所述刚性支撑条2通过所述柔性支撑层3组成对应于柔性显示屏10的可弯折区的支撑结构，在弯折时，所述柔性支撑层3位于相邻的两个所述刚性支撑条2之间的部分拉伸、形变，保证柔性显示屏10的弯折性能，而所述刚性支撑条2的设置保证了柔性显示屏10的可弯折区的机械强度，刚柔并济，可有效克服柔性显示屏10的可弯折区的平整度和支撑性问题，大大提高终端组装信赖性。
本实施例中，多个所述刚性支撑条2为长方体结构，多个所述刚性支撑条2的形状相同，且多个所述刚性支撑条2均匀分布于所述柔性支撑层3的所述第二区域，但并不以此为限。
本实施例中，所述第一区域的数量的设置与柔性显示屏10上的非弯折区的数量相同，所述第二区域的数量的设置与柔性显示屏10上的可弯折区的数量相同，以便使得位于所述第一区域的所述刚性支撑平板1对应支撑于柔性 显示屏10的非弯折区，位于所述第二区域的所述刚性支撑条2对应支撑于柔性显示屏10的可弯折区。
本实施例中，为了避免柔性显示屏10的可弯折区和非弯折区的连接处在弯折时出现折痕，与所述刚性支撑平板1相邻的所述刚性支撑条2与对应的所述刚性支撑平板1之间的间隙为零，参考图5和图6。
由于多个所述刚性支撑条2是相互独立的，通过所述柔性支撑层3连接在一起，为了增加所述刚性支撑条2的连接稳定性，本实施例中，所述柔性支撑层3还包括凸设于相邻两个所述刚性支撑条2之间的柔性条形凸出部，参考图5和图6。
本实施例中，所述柔性条形凸出部与所述柔性支撑层3为一体结构。
所述柔性条形凸出部的设置增加了所述柔性支撑层3与所述刚性支撑条2之间的连接面积，进而增加了所述刚性支撑条2与所述柔性支撑层3之间的连接强度。
本实施例中，所述柔性条形凸出部和所述柔性支撑层均采用橡胶或硅胶制成，但并不以此为限，只要制成所述柔性条形凸出部和所述柔性支撑层的柔性材料具有较高的弹性和自我恢复能力(利于柔性显示屏由弯折状态转换为平面状态)即可。
本实施例中，所述柔性条形凸出部向靠近所述第一表面的方向凹陷形成条形凹槽31，所述条形凹槽的延伸方向与所述柔性条形凸出部的延伸方向相同。
参考图5和图6，所述条形凹槽31的开口方向背向柔性显示屏10，柔性显示屏10弯折时，所述条形凹槽31的两个侧壁相向运动，减小了所受应力，提高了可弯折性能。
所述条形凹槽31的深度以及所述条形凹槽31在所述第一方向上的宽度可根据实际需要设定，本实施例的一个实施方式中，所述条形凹槽31的深度与所述刚性支撑条2的厚度(在垂直于所述柔性支撑层3的方向上的厚度)相同，但并不以此为限。
所述条形凹槽31的深度以及所述条形凹槽31在所述第一方向上的宽度的设定要满足以下条件：在柔性显示屏10的可弯折区域弯折至最大弯折状态时(一般是形成半圆弧状态)，所述条形凹槽31的两个侧壁刚好接触，即所述条 形凹槽31的两个侧壁既不会在柔性显示屏10弯折至最大弯折状态之前接触，限制了柔性显示屏10的弯折程度；也不会在柔性显示屏10弯折至最大弯折状态时，所述条形凹槽31的两个侧壁之间具有间隔，致使影响柔性显示屏10的可弯折区的机械强度。
本实施例中，所述刚性支撑平板1在垂直于所述柔性支撑层的方向上的厚度与所述刚性支撑条2在垂直于所述柔性支撑层3的方向上的厚度相同，所述刚性支撑平板1在垂直于所述柔性支撑层的方向上的厚度为0.3-0.5mm，但并不以此为限。
本实施例中，相邻两个所述刚性支撑条2之间的间距为0.6-1.2mm，但并不以此为限。
本实施例中，所述刚性支撑条2在第二方向上的宽度为1.0-1.5mm，所述第二方向平行于所述第二表面、且垂直于所述刚性支撑条的延伸方向(所述第二方向即所述第一方向)，但并不以此为限。
本实施例中，所述刚性支撑平板1和所述刚性支撑条2均采用金属制成，在保证支撑性能的同时，可以具有散热的作用。
本实施例的一实施方式中，所述刚性支撑平板1和所述刚性支撑条2均采用铜制成，但并不以此为限。
本实施例中，所述柔性支撑层3采用橡胶等柔性材料制成，具有一定拉伸量和回复能力，补偿柔性显示屏10弯折过程中可弯折区所需的变形量。
本实施例中，所述柔性支撑层3通过注塑工艺形成，且通过注塑工艺形成所述柔性支撑层3的同时，将所述柔性支撑层3与所述刚性支撑平板1和所述刚性支撑条2通过注塑工艺连接为一体，简化工艺，且提高了所述柔性支撑层3、所述刚性支撑平板1和所述刚性支撑条2之间的连接稳定性。
本实施例中，所述柔性显示屏支撑结构还包括能够围设于所述柔性显示屏10的四周的保护外框4，所述刚性支撑平板1包括外露于所述柔性支撑层3的所述第一区域的边缘连接部，所述保护外框4连接于所述边缘连接部上，参考图3和图4。
所述保护外框4与所述柔性支撑层3、所述刚性支撑平板1、所述刚性支撑条2连接为一整体，形成能够容纳柔性显示屏10的容纳空间，所述保护外 框4围设与柔性显示屏10的四周，可以保护柔性显示屏10。
所述柔性显示屏10的出光侧设置有盖板20，所述盖板20包括覆盖所述柔性显示屏10的中心区域，和外露于所述柔性显示屏10的外围区域，在垂直于所述刚性支撑平板的方向上、所述保护外框4包括设置于所述盖板20的四周的第一部分41和位于所述柔性显示屏10的四周的第二部分42，所述第一部分41和所述第二部分42形成了与所述盖板20的外围区域进行搭接的台阶结构，以起到保护盖板20的作用，参考图7。
本实施例中，所述边缘连接部包括多个通孔11，所述保护外框4还包括能够插入所述通孔11的第三部分43。
参考图7，所述通孔11的设置提高了所述保护外框4和所述刚性支撑平板1之间的连接稳定性。
多个所述通孔11均匀设置于所述边缘连接部，所述刚性支撑平板1为矩形，包括与所述刚性支撑条2相邻的第一边，以及除第一边之外的其他三个边，所述边缘连接部包括了除第一边之外的其他三个边，每个边沿其延伸方向均匀设置多个所述通孔11。
本实施例中，所述保护外,4包括与所述刚性支撑平板1连接的第一连接部分，和于所述刚性支撑条2连接的第二连接部分，所述第一连接部分连接于所述边缘连接部，所述第二连接部分包括向远离所述柔性支撑层3的方向延伸、并遮挡所述刚性支撑条2的两个端部的两个遮挡部。
所述遮挡部远离所述柔性支撑层3的一端与所述刚性支撑平板1远离所述柔性支撑层3的表面平齐，使得所述刚性支撑条2位于所述保护外框4的内部，避免所述刚性支撑条2外露，起到保护所述刚性支撑条2的作用，避免所述刚性支撑条2直接受到外力而与所述柔性支撑层3分离，且起到了美化外观的作用。
本实施例中，所述保护外框4采用柔性材料制成。
本实施例的一实施方式中，所述保护外框4采用橡胶材料注塑成型，所述保护外框4为一整体结构，且所述保护外框4与连接为一体的所述刚性支撑平板1、所述刚性支撑条2、所述柔性支撑层3之间的连接也是通过注塑工艺实现的，简单快捷。
