具体实施方式
为了更清楚地说明本公开，下面结合实施例和附图对本公开做进一步的说明。附图中相似的部件以相同的附图标记进行表示。本领域技术人员应当理解，下面所具体描述的内容是说明性的而非限制性的，不应以此限制本公开的保护范围。
目前，为克服因拉伸或弯折引起的受力不均，提高柔性显示面板的拉伸性能，柔性显示面板一般在衬底和保护膜层上设置孔洞，如图1所示，所述柔性显示面板未受力时，所述衬底或保护膜层上的孔洞正常分布，并且各孔洞处于正常状态，差异较小，并且柔性显示面板显示的图像画面清晰、均匀。然而当柔性面板受到拉伸作用后，由于拉力集中作用在某一区域，使得所述衬底和保护膜层上的孔洞的变形量不同，如图2所示，在拉力线上和边缘位置的孔洞的变形量较大，而远离拉力作用线区域的孔洞的变形量则较小，此时所述柔性显示面板显示的图像画面出现扭曲，均一性较差。
为解决上述存在的问题，如图3所示，本公开的一个实施例提供了一种柔性衬底100，所述柔性衬底包括第一部1和在所述第一部侧面处的第二部2，其中所述第一部1的弹性模量小于所述第二部2的弹性模量。
在一个具体的示例中，以所述柔性衬底上分布有孔洞进行说明，如图3和图4所示，为解决柔性衬底在拉伸过程中因受力不均匀造成的孔洞变形差异，在所述第一部1的侧面处设置有所述第二部2，该侧面垂直于第一部1的延伸平面，其中所述侧面处不限于所述第一部1的单侧、双侧或者周边位置，以能够承受拉伸力并分散拉伸力为设计准则，所述第二部2的弹性模量大于第一部1的弹性模量，即所述第二部2能够更好地承受拉伸力。因此，当该柔性衬底100处于拉伸过程中时，设置在侧面处的具有较大弹性模量的第二部2能够将受到的拉伸力均匀作用在孔洞处，更好地分散集中力，从而减小孔洞间的变形差异量。
第二部2可以包括多个子部分21，多个子部分分别位于第一部的不同的 侧面处。例如，如图3和图4所示，子部分21的数量为两个，两个子部分分别位于第一部1的相对的侧面处；替代地，子部分21的数量可以为四个，四个子部分围绕第一部1的外周。
在一个具体的实施例中，如图5和图6所示，所述第二部2包括弹性材料，所述第二部2与所述第一部1贴合设置。所述第二部2为弹性模量较大的弹性材料，包括但不限于橡胶材料或不锈钢(SUS)材料，贴合在所述第一部1上，并且所述第二部2与所述第一部1的贴合的接触面积越大越有利于分散受到的外力，从而降低所述柔性衬底上孔洞的变形差异。
在另一个具体的实施例中，如图7和图8所示，所述第二部2由一材料层的侧面端掺杂弹性材料而形成，所述材料层未掺杂的部分形成所述第一部1，其中所述弹性材料的弹性模量大于所述第一部1的弹性模量。这里，材料层的侧面端是指材料层的靠近材料层的垂直于材料层的延伸平面的侧面的一端。所述第二部2掺杂具有较大弹性模量的弹性材料，例如先形成一材料层，然后在所述材料层的侧面端掺杂橡胶材料或SUS材料等弹性模量较大的颗粒3形成所述第二部2，使得所述第二部2的整体弹性模量增大以能够有效减小外力对孔洞的变形差异，其余未掺杂弹性材料的材料层形成第一部1。
与上述实施例提供的柔性衬底相对应，本公开的一个实施例提供一种柔性衬底的制作方法，由于本实施例提供的柔性衬底的制作方法与上述实施例提供的柔性衬底相对应，因此前述实施方式也适用于本实施例提供的制作方法，在本实施例中不再详细描述。
如图9所示，一种柔性衬底的制作方法，包括在柔性衬底基体的侧面处贴合弹性材料，或者对柔性衬底基体的侧面端掺杂弹性材料，所述侧面垂直于柔性衬底基体的延伸平面，其中柔性衬底基体的弹性模量小于所述弹性材料的弹性模量。所述柔性衬底既可以通过在侧面处贴合弹性模量大的弹性材料、又可以通过在侧面端掺杂弹性模量大的弹性材料，从而增加所述柔性衬底对拉伸力的承受和分散能力。
与上述实施例提供的柔性衬底相对应的，如图10和11所示，本公开的一个实施例还提供一种柔性显示面板200，包括柔性衬底22、显示功能层23和保护膜层，所述柔性衬底22和/或保护膜层分别包括对应于所述显示功能层的显示区域的第一区域25、对应于所述显示功能层的非显示区域的第二区域26，其中所述柔性衬底22和/或保护膜层的所述第一区域25的弹性模量小于所述第二区域26的弹性模量。保护膜层的数量可以为两个，为第一保护膜层和第 二保护膜层，第一保护膜层可以为背膜21，第二保护膜层可以为盖板24。
在一个具体的示例中，图10所示的柔性显示面板200包括柔性衬底22，包括子像素、圆偏光片、光学透明胶和触摸屏面板的显示功能层23，位于所述柔性衬底22远离所述显示功能层23一侧的背膜21和位于所述显示功能层远离所述柔性衬底一侧的盖板24。其中背膜21为设置在柔性衬底22外侧的膜层，用于支撑和保护柔性显示面板；盖板24为设置在显示功能层23外侧的膜层，相当于柔性显示面板的外壳，用于保护柔性显示面板200。
为解决柔性显示面板在拉伸过程中因受力不均匀造成的变形差异，可以在柔性衬底22上或者包括背膜21和盖板24的保护膜层上分别设置第一区域25和第二区域26，也可以在柔性衬底22上和保护膜层上同时设置第一区域25和第二区域26，本领域技术人员应当根据实际应用情况进行设计。其中所述第一区域25对应柔性显示面板200的显示区域，所述第二区域26对应柔性显示面板200的非显示区域，并且所述第二区域26的弹性模量大于所述第一区域25的弹性模量。因此当所述柔性显示面板200受到横向或纵向的集中力时，通过在所述柔性衬底22和/或包括背膜21和盖板24的保护膜层上设置弹性模量较大的第二区域可以有效的分散集中力，使得外力能够均匀的作用在所述柔性衬底上，从而降低所述变形差异，明显改善所述柔性显示面板200的显示效果。作为一个替代方案，也可以仅在两个保护膜层中的一个上设置第一区域25和第二区域26，而不再另一个上设置第二区域26。
在一个具体的实施例中，如图12所示，所述第二区域26包括弹性材料，所述第二区域26与所述第一区域25贴合设置。所述第二区域26使用的弹性材料包括但不限于橡胶材料或SUS材料，以能够有效降低所述变形差异为准。
在另一个具体的实施例中，如图13所示，所述第二区域26由一材料层的侧面端掺杂弹性材料而形成，所述材料层未掺杂的部分形成所述第一区域25，其中所述弹性材料的弹性模量大于所述第一区域25的弹性模量。所述第二区域26掺杂有具有较大弹性模量的弹性材料，例如先形成材料层，在所述材料层的侧面中掺杂橡胶或SUS等弹性模量较大的粒子以获得所述第二区域26，其余未掺杂弹性材料的材料层形成第一区域25，如此所述第二区域26的整体弹性模量增大，能够有效缓解因外力导致的所述变形差异不同，进而提高显示效果。
进一步地，所述柔性衬底22、背膜21和盖板24的第二区域26可以分别使用不同的弹性材料，本领域技术人员应当根据柔性衬底、背膜和盖板各自的 材料、材料的特点、制作工艺和成本选择使用匹配的弹性材料。
本公开的实施例针对目前的柔性显示面板在拉伸时因变形量不一致出现的显示不均的问题，提供了一种柔性衬底和柔性显示面板，通过在柔性衬底和保护膜层的非显示区使用弹性模量大于显示区弹性模量的弹性材料，能够提高在拉伸状态时所述显示面板显示的均匀性，有效改善所述显示面板的显示效果，提高用户体验。
与上述实施例提供的柔性显示面板相对应，如图14所示，本公开的一个实施例提供一种柔性显示面板的制作方法，由于本实施例提供的柔性显示面板的制作方法与上述几种实施例提供的柔性显示面板相对应，因此前述实施方式也适用于本实施例提供的制作方法，在本实施例中不再详细描述。
如图14所示，本公开的一个实施例还提供一种柔性显示面板的制作方法，包括：形成柔性衬底；在所述柔性衬底上形成显示功能层；形成保护膜层，其中所述保护膜层包括在所述柔性衬底远离所述显示功能层一侧形成的背膜和在所述显示功能层远离所述柔性衬底一侧形成的盖板；其中所述柔性衬底和/或保护膜层分别包括对应于所述显示功能层的显示区域的第一区域、对应于所述显示功能层的非显示区域的第二区域，其中所述柔性衬底和/或保护膜层的所述第一区域的弹性模量小于所述第二区域的弹性模量。
进一步地，所述制作方法还包括：在所述第一区域侧面处贴合弹性材料以形成所述第二区域；或者形成材料层，以及在所述材料层侧面端掺杂弹性材料以形成所述第二区域，未掺杂的区域形成所述第一区域。
本公开的另一个实施例还提供一种柔性显示装置，包括上述实施例中的柔性显示面板。所述柔性显示装置可以为OLED电视、显示器、手机等任何具有显示功能的产品或部件。
作为对本公开的实施例的补充，图15示出了根据本公开的又一个实施例的柔性衬底，该实施例的柔性衬底与图5和图6所示的实施例的柔性衬底的差别在于：在第一部1的侧面处设置的第二部2包括多段膜材，即多段膜材依次贴合并贴合在第一部1的侧面处，各段膜材的弹性模量与第一部1的弹性模量不同，并且各段膜材之间的弹性模量也不相同，有利地，沿从外边缘向内侧的方向，各段膜材的弹性模量逐渐降低。由此，可以实现弹性模量由外向内逐渐的改变，更好地实现减小孔洞变形量差异，提高显示效果的作用。
相似地，图16示出了根据本公开的又一个实施例的柔性衬底，该实施例的柔性衬底与图7和图8所示的实施例的柔性衬底的差别在于：第二部2掺 杂的颗粒3的掺杂浓度由外边缘向内侧(由从第二部向第一部的方向)逐渐降低，由此第二部由外边缘向内侧弹性模量逐渐降低，进一步提高显示效果。
关于多段膜材贴合在第一部上的方案以及第二部掺杂的颗粒的掺杂浓度由外边缘向内侧逐渐降低的方案同样适用于保护膜层，即背膜或盖板，因此，在背膜21和盖板24的第二区域可以包括多段膜材，并且沿从外边缘向内侧的方向，各段膜材的弹性模量逐渐降低，或者在背膜21和盖板24的第二区域掺杂的颗粒的掺杂浓度由外边缘向内侧逐渐降低。
此外，在柔性衬底22、背膜21和盖板24上的第二区域的膜材的材料可以相同，也可以不同；在柔性衬底22、背膜21和盖板24上的第二区域掺杂的颗粒的掺杂浓度的变化规律可以相同，也可以不同。本公开的实施例针对目前的柔性显示面板在拉伸时因柔性衬底的变形量不一致出现的显示不均的问题，通过在柔性显示面板的柔性衬底和保护膜层的非显示区使用弹性模量大于显示区弹性模量的弹性材料，能够解决在拉伸状态时所述柔性显示面板显示的不均匀性的问题，有效改善所述柔性显示面板的显示效果，提高用户体验。
显然，本公开的上述实施例仅仅是为清楚地说明本公开所作的举例，而并非是对本公开的实施方式的限定，对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动，这里无法对所有的实施方式予以穷举，凡是属于本公开的技术方案所引伸出的显而易见的变化或变动仍处于本公开的保护范围之列。
