Description

显示组件和显示装置
交叉引用
本公开要求于2020年10月26日提交的申请号为202011155997.X名称为“显示组件和显示装置”的中国专利申请的优先权，该中国专利申请的全部内容通过引用全部并入本文。
技术领域
本公开涉及显示技术领域，尤其涉及一种显示组件和包括该显示组件的显示装置。
背景技术
近年来，柔性OLED(OrganicElectroluminesence Display，有机发光半导体)显示装置吸引了众多用户的关注，其中拉伸显示是柔性OLED必不可少的组成部分。
目前，大部分的柔性显示面板3的可拉伸显示区A包括：岛区(显示单元区)、桥区(连接单元区)和镂空区，相邻的岛区通过桥区相连，通过镂空区域的伸展而达到一定的拉伸性能。参照图1所示，柔性显示面板3还包括与可拉伸显示区A连接的易断裂区B，与易断裂区B连接的绑定区C。在柔性显示面板3的背面贴有弹性背膜2，用于支撑和保护镂空装置。但是，柔性显示面板3在搭载IC(Integrated Circuit，集成电路)芯片1时，需进行绑定工艺，该工艺要求精度较高，若在弹性背膜2支撑的柔性显示面板3上进行该工艺，当绑定开始时，作用力会使弹性背膜2以及柔性显示面板3都产生形变，容易导致IC芯片1的绑定触点11与绑定区C的连接触点31错位而绑定失败，最终IC芯片1无法正确控制柔性显示面板3。

具体实施方式
现在将参考附图更全面地描述示例实施方式。然而，示例实施方式能够以多种形式实施，且不应被理解为限于在此阐述的实施方式；相反，提供这些实施方式使得本发明将全面和完整，并将示例实施方式的构思全面地传达给本领域的技术人员。图中相同的附图标记表示相同或类似的结构，因而将省略它们的详细描述。
本示例实施方式首先提供了一种显示组件，参照图2至图7所示的本发明显示组件多个示例实施方式的结构示意图；该显示组件可以包括柔性显示面板3、第一支撑膜4以及第二支撑膜5；柔性显示面板3包括依次连接的可拉伸显示区A、易断裂区B和绑定区C；第一支撑膜4设于所述可拉伸显示区A的一侧；第二支撑膜5设于绑定区C的一侧，且所述第二支撑膜5与所述第一支撑膜4位于所述柔性显示面板3的同一侧；其中，所述第一支撑膜4的延伸率大于所述第二支撑膜5的延伸率，所述第一支撑膜4的硬度小于所述第二支撑膜5的硬度。
在本示例实施方式中，柔性显示面板3的可拉伸显示区A可以包括：岛区(显示单元区)、桥区(连接单元区)和镂空区(在图中均未示出)，相邻的岛区通过桥区相连。岛区 内用于设置发光单元，发光单元包括有机发光图形。易断裂区B连接于可拉伸显示区A和绑定区C之间，易断裂区B集中有连接可拉伸显示区A和绑定区C的金属导线32，因此极易断裂。绑定区C内设置有多个连接触点31，绑定区C的连接触点31用于与IC芯片1的绑定触点11进行绑定，以连接IC芯片1与柔性显示面板3。
在本示例实施方式中，第一支撑膜4的延伸率大于第二支撑膜5的延伸率，具体地，第一支撑膜4的延伸率大于等于20％且小于等于40％，第二支撑膜5的延伸率小于等于3％。延伸率是描述材料塑性性能的指标，延伸率即试样拉伸断裂后标距段的总变形与原标距长度之比的百分数。
在本示例实施方式中，第一支撑膜4的硬度小于第二支撑膜5的硬度，具体地，第一支撑膜4的硬度大于等于1MPa且小于等于10Mpa，第二支撑膜5的硬度大于等于1GPa且小于等于10Gpa。
由于第一支撑膜4和第二支撑膜5材料性质相差较大，因此无法做成一体式膜材。第一支撑膜4设于可拉伸显示区A的一侧，第二支撑膜5设于绑定区C的一侧，第一支撑膜4的靠近第二支撑膜5的一端与第二支撑膜5的靠第一支撑膜4的一端可以相互搭接，第二支撑膜5与第一支撑膜4搭接的宽度大于等于1毫米且小于等于2毫米。第一支撑膜4的相对的另一端可以突出于可拉伸显示区A，第二支撑膜5的相对的另一端可以突出于绑定区C。第一支撑膜4的另外两端可以突出于可拉伸显示区A，也可以与可拉伸显示区A齐平；第二支撑膜5的另外两端可以突出于绑定区C，也可以与绑定区C齐平。第一支撑膜4与第二支撑膜5搭接的具体实施例如下：
参照图2和图3所示的本发明显示组件第一示例实施方式的结构示意图；第二支撑膜5的靠近第一支撑膜4的一端位于柔性显示面板3与第一支撑膜4之间。可以将第二支撑膜5的一端粘接至第一支撑膜4之上，然后将柔性显示面板3贴覆至第一支撑膜4和第二支撑膜5之上。且第二支撑膜5位于绑定区C的下方，第一支撑膜4位于可拉伸显示区A的下方。由于第一支撑膜4与第二支撑膜5之间搭接，第一支撑膜4延伸至易断裂区B和第二支撑膜5的靠近第一支撑膜4的一端的下方，使第二支撑膜5的靠近第一支撑膜4的一端位于柔性显示面板3与第一支撑膜4之间。由于第一支撑膜4和第二支撑膜5的搭接，第一支撑膜4的上表面和第二支撑膜5的上表面不在一个平面内具有高度差，使易断裂区B形成倾斜状，为了减小易断裂区B断裂的可能性，需要设计较小的高度差，即第二支撑膜5在确保绑定工艺要求的硬度的前提下使其厚度尽可能小，例如，第二支撑膜5的厚度为大于等于50微米且小于等于500微米。
参照图4所示的本发明显示组件第二示例实施方式的结构示意图；第一支撑膜4的靠近第二支撑膜5的一端位于柔性显示面板3与第二支撑膜5之间。可以将第一支撑膜 4的一端粘接至第二支撑膜5之上，然后将柔性显示面板3贴覆至第一支撑膜4和第二支撑膜5之上，且第二支撑膜5位于绑定区C的下方，第一支撑膜4位于可拉伸显示区A的下方。由于第一支撑膜4与第二支撑膜5之间搭接，第二支撑膜5延伸至易断裂区B和第二支撑膜5下方，使第一支撑膜4的靠近第二支撑膜5的一端位于柔性显示面板3与第二支撑膜5之间。由于第一支撑膜4和第二支撑膜5的搭接，第一支撑膜4的上表面和第二支撑膜5的上表面不在一个平面内具有高度差，使易断裂区B形成倾斜状，为了减小易断裂区B断裂的可能性，需要设计较小的高度差，即第一支撑膜4在确保拉伸和支撑作用的前提下使其厚度尽可能小，例如，第一支撑膜4的厚度为大于等于100微米且小于等于500微米。
另外，第一支撑膜4的靠近第二支撑膜5的一端与第二支撑膜5的靠第一支撑膜4的一端也可以不相互搭接，而第一支撑膜4的相对的另一端可以突出于可拉伸显示区A，第二支撑膜5的相对的另一端可以突出于绑定区C。第一支撑膜4的另外两端可以突出于可拉伸显示区A，也可以与可拉伸显示区A齐平；第二支撑膜5的另外两端可以突出于绑定区C，也可以与绑定区C齐平。具体实施例如下：
参照图5所示的本发明显示组件第三示例实施方式的结构示意图；第二支撑膜5位于绑定区C的下方，且第二支撑膜5的靠第一支撑膜4的一端延伸至易断裂区B的下方；第一支撑膜4位于可拉伸显示区A的下方，且第一支撑膜4的靠近第二支撑膜5的一端延伸至易断裂区B的下方；第二支撑膜5与第一支撑膜4之间设置有间隙6，即第一支撑膜4与第二支撑膜5不搭接，间隙6在柔性显示面板3上的正投影位于易断裂区B内，使易断裂区B部分处于悬空状态。此时间隙6的宽度小于2mm。
参照图6所示的本发明显示组件第四示例实施方式的结构示意图；该示例实施方式与图5所示的示例实施方式的主要区别在于：第二支撑膜5仅位于绑定区C的下方，并没有延伸至易断裂区B的下方；第一支撑膜4仅位于可拉伸显示区A的下方，并没有延伸至易断裂区B的下方；即间隙6在柔性显示面板3上的正投影与易断裂区B重合。此时间隙6的宽度较宽与易断裂区B的宽度相同，大约为2mm，使易断裂区B悬空。
当然，在本发明的其他示例实施方式中，可以是第一支撑膜4的靠近第二支撑膜5的一端延伸至易断裂区B，但是，第二支撑膜5并没有延伸至易断裂区B的下方。还可以是第一支撑膜4没有延伸至易断裂区B的下方，但是，第二支撑膜5的靠第一支撑膜4的一端延伸至易断裂区B的下方。这种情况下，间隙6的宽度小于2mm。
参照图7所示的本发明显示组件第五示例实施方式的结构示意图；该示例实施方式与图5所示的示例实施方式的主要区别在于，第二支撑膜5位于绑定区C的下方，且第二支撑膜5的靠第一支撑膜4的一端延伸至易断裂区B的下方；第一支撑膜4位于可拉 伸显示区A的下方，且第一支撑膜4的靠近第二支撑膜5的一端延伸至易断裂区B的下方；第二支撑膜5的靠近第一支撑膜4的一端面与第一支撑膜4的靠近第二支撑膜5的一端面接触，接触处在柔性显示面板3上的正投影位于易断裂区B。在本方面的其他示例实施方式中，第二支撑膜5的靠近第一支撑膜4的一端面与第一支撑膜4的靠近第二支撑膜5的一端面可以通过粘接胶粘接为一体。在易断裂区B也提供有支撑，使易断裂区B不容易断裂。
还有，在本发明的其他示例实施方式中，可以是第一支撑膜4的靠近第二支撑膜5的一端延伸至易断裂区B直至与第二支撑膜5接触，但是，第二支撑膜5并没有延伸至易断裂区B的下方。还可以是第一支撑膜4没有延伸至易断裂区B的下方，但是，第二支撑膜5的靠第一支撑膜4的一端延伸至易断裂区B的下方直至与第一支撑膜4接触。
需要说明的是，在图5、图6和图7所示的示例实施方式中，第一支撑膜4的厚度与第二支撑膜5的厚度可以相同，为柔性显示面板3提供较为平整的支撑面，使易断裂区B不容易断裂。第二支撑膜5可以采用多层膜的结构，以保持与第一支撑膜4相同的厚度，当然，第一支撑膜4页可以采用多层膜的结构，以保持与第二支撑膜5相同的厚度。
参照图8所示的本发明显示组件与IC芯片绑定后的结构示意图，将绑定区C和可拉伸显示区A的支撑膜进行分别设置，使可拉伸显示区A的第一支撑膜4满足拉伸要求，在拉伸时，第一支撑膜4有足够的延伸率能够保证可拉伸显示区A的拉伸量；绑定区C的第二支撑膜5满足绑定要求，在绑定时，第二支撑膜5有足够的硬度能够支撑柔性显示面板3的绑定区C使其不容易产生形变，不容易导致绑定触点11与绑定区C的连接触点31错位而绑定失败，不会使IC芯片1无法正确控制柔性显示面板3。
而且，如果开发新的绑定工艺耗时较长、成本较高、可行性较低，本申请使用第一支撑膜和第二支撑膜有效解决该问题，既不影响拉伸效果，又可以使用原有工艺进行绑定，成本低，可行性较高。
进一步的，本发明还提供了一种显示装置，该显示装置可以包括上述任意一项所述的显示组件。显示组件的具体结构上述已经进行了详细说明，因此，此处不再赘述。

本说明书中，用语“一个”、“一”、“该”和“所述”用以表示存在一个或多个要素/组成部分/等；用语“包含”、“包括”和“具有”用以表示开放式的包括在内的意思并且是指除了列出的要素/组成部分/等之外还可存在另外的要素/组成部分/等；用语“第一”、“第二”和“第三”等仅作为标记使用，不是对其对象的数量限制。
