内折柔性模组在折叠时会为柔性模组提供一个收纳空间，目前研究中柔性模组内折为水滴形是发展的一个重要的趋势。如图1所示为柔性模组内折为水滴形的示意图。
公开技术中能内折为水滴形的柔性模组叠构，由于柔性模组叠构中膜层差异化设计缺陷导致膜层匹配性较差及水滴形形态设计不合理，在柔性模组内折测试中出现胶层开胶不良和柔性模组显示功能层失效不良。
为降低胶材开胶不良和柔性模组显示失效风险，对柔性模组中各膜层进行匹配性设计并优化水滴形形态，本公开实施例提供一种显示模组和显示装置。
本公开实施例提供一种显示模组，如图2和图3所示，包括：柔性面板1、通过第一胶层组2贴设于柔性面板1出光侧的第一膜层组3、通过第二胶层组4贴设于柔性面板1背离出光侧的非出光侧的第二膜层组5；显示模组可折叠形成曲面板，显示模组在垂直于曲面板的第一平面上的正投影至少部分呈水滴轮廓6状，水滴轮廓6包括颈部61和本体部62，显示模组的相对两端在第一平面上的正投影至少部分形成颈部61，显示模组的位于相对两端之间的中间部分在第一平面上的正投影形成本体部62；颈部61呈圆弧线，圆弧线上任意一点的曲率半径R范围为16～20mm；本体部62呈弧线，弧线上任意一点的曲率半径R＇范围为4±0.5mm。
在一些实施例中，柔性面板1采用OLED(OrganicLight-Emitting Diode，有机电激发光)面板。柔性面板1本身在折叠时的应变在安全范围内，其本身的显示性能不会受到影响。
其中，本实施例中的显示模组通过对其中各膜层的匹配性进行优化，能够使该显示模组显示侧朝内折叠为至少部分呈水滴轮廓6状，且该水滴 轮廓6的颈部61和本体部62满足上述曲率半径参数范围，从而优化了显示模组折叠后形成的水滴轮廓6形状，进而降低了显示模组内折时其内部各膜层所受应变，减少或避免显示模组内折测试中出现胶层开胶不良和显示功能层失效不良，使该显示模组能够通过信赖性测试目标。
本实施例中，显示模组在垂直于曲面板的第一平面上的正投影整体呈水滴轮廓6状。需要说明的是，显示模组在垂直于曲面板的第一平面上的正投影也可以只有部分呈水滴轮廓6状，即显示模组还有一部分为未弯折的平面状；该未弯折的平面状部分可以是显示模组的相对两端(如图4所示)，也可以是显示模组的其中一端(如图5所示)。
在一些实施例中，第一膜层组3包括偏光片31和盖板32，第一胶层组2包括第一子胶层21和第二子胶层22，第一子胶层21、偏光片31、第二子胶层22和盖板32依次叠置于柔性面板1的出光侧；第二膜层组5包括背膜51和支撑膜52，第二胶层组4包括第三子胶层41和第四子胶层42，第三子胶层41、背膜51、第四子胶层42和支撑膜52依次叠置于柔性面板1的非出光侧。
需要说明的是，第一膜层组3不限于偏光片31和盖板32，还可以设置其他叠置膜层；第一胶层组2也不限于第一子胶层21和第二子胶层22，还可以设置其他叠置子胶层；第二膜层组5不限于背膜51和支撑膜52，还可以设置其他叠置膜层；第二胶层组4也不限于第三子胶层41和第四子胶层42，还可以设置其他叠置子胶层。
在一些实施例中，第二子胶层22和第四子胶层42采用光学透明胶；第一子胶层21和第三子胶层41采用压敏胶。
如图6和图7所示，提高背膜51模量可降低光学透明胶胶材的第二子胶层22和第四子胶层42以及柔性面板1中各功能层的应变，但将增大压敏胶胶材的第一子胶层21和第三子胶层41的应变，因此需要对背膜51、第二子胶层22、第四子胶层42、第一子胶层21、第三子胶层41等膜层的 模量、厚度进行匹配性设计以达到使整个显示模组通过信赖性测试的目标。
在一些实施例中，第二子胶层22与第四子胶层42为柔性层且采用相同材料，第二子胶层22与第四子胶层42在25℃时模量范围为55KPa±10Kpa；第二子胶层22与第四子胶层42在-20℃时模量范围为120KPa±10KPa；第二子胶层22与第四子胶层42在60℃时模量范围为35KPa±5Kpa。
在一些实施例中，第二子胶层22与第四子胶层42的厚度相同且固化率相同，第二子胶层22与第四子胶层42的固化率范围为68％±3％；第二子胶层22与第四子胶层42的厚度范围为50μm±5μm。
在一些实施例中，偏光片31采用柔性材料，偏光片31的模量范围为3.2GPa±0.5Gpa。
在一些实施例中，偏光片31的厚度范围为45μm±5μm。
在一些实施例中，第一子胶层21采用柔性材料，第一子胶层21在25℃时模量范围为510KPa±10KPa；第一子胶层21在-20℃时模量范围为0.29MPa±0.01MPa；第一子胶层21在60℃时模量范围为370KPa±10KPa。
在一些实施例中，第一子胶层21的厚度范围为15μm±5μm。
在一些实施例中，第三子胶层41采用柔性材料，第三子胶层41在25℃时模量范围为45KPa±10KPa；第三子胶层41在-20℃时模量范围为130KPa±10KPa；第三子胶层41在60℃时模量范围为40KPa±5KPa。
在一些实施例中，第三子胶层41的厚度范围为15μm±3μm。
在一些实施例中，背膜51采用柔性材料，背膜51的模量范围为3.2GPa±0.5GPa。
在一些实施例中，背膜51的厚度范围为23μm±3μm。
在一些实施例中，盖板32采用柔性材料，盖板32的厚度范围为85μm±5μm。
在一些实施例中，如图8所示，支撑膜52包括多个子块520，多个子块520呈阵列等间隔排布。支撑膜52可以采用钢片，由于支撑膜52由多 个间隔排布的子块520构成，所以使的支撑膜52一方面对柔性面板1具有一定的支撑作用，同时还能使柔性面板1良好地展平于其上；另一方面支撑膜52还能随柔性面板1折叠时的形态变化而进行相应形态的变化，使柔性面板1不会受到支撑膜52应变的影响。
在一些实施例中，支撑膜52的厚度范围为30μm±10μm。
通过对显示模组中各膜层模量、厚度的上述匹配性优化，降低了显示模组内折时其内部各膜层所受应变，减少或避免显示模组内折测试中出现胶层开胶不良和显示功能层失效不良，使该显示模组能够通过信赖性测试目标；同时还优化了显示模组折叠后形成的水滴轮廓6形状。
在一些实施例中，如图3所示，颈部61的远离本体部62的一端至颈部61与本体部62交界线的距离L范围为7～12mm。采用治具7辅助显示模组进行弯折。显示模组弯折时，治具7设置于显示模组的相对两端部，且治具7相对两端部的其中一端(这里称第一端71)与显示模组的端部粘贴在一起，治具7的另一端(这里称第二端72)与显示模组端部以内的部分粘贴在一起。颈部61与本体部62的交界线指的是治具7的与显示模组粘贴的第二端72边缘线对应的显示模组上的分界线。
在一些实施例中，本体部62的弧线长度范围为38±5cm。本体部62的弧线长度具体根据显示模组的尺寸大小决定。
本公开实施例还提供一种显示模组，与上述实施例中不同的是，如图2所示，第二子胶层22与第四子胶层42为柔性层且采用不同材料，第二子胶层22在25℃时模量范围为55KPa±10Kpa；第二子胶层22在-20℃时模量范围为120KPa±10KPa；第二子胶层22在60℃时模量范围为35KPa±5KPa；第四子胶层42在25℃时模量范围为30KPa±5KPa；第四子胶层42在-20℃时模量范围为190KPa±10KPa；第四子胶层42在60℃时模量范围为15KPa±3Kpa。
本实施例中显示模组的其他膜层结构及参数设置与上述实施例中相同，此处不再赘述。
将膜层匹配性优化前与上述两公开实施例中膜层匹配性优化后显示模组中各胶层的应变进行比较，如图9所示，上述两公开实施例中第二子胶层22和第四子胶层42的应变均较小，从而降低了第二子胶层22和第四子胶层42的开胶风险，同时，膜层匹配性优化前与上述两公开实施例中第一子胶层21的应变保持稳定。膜层匹配性优化前与上述第二个公开实施例中第三子胶层41的应变相当，上述第一个公开实施例中第三子胶层41的应变增加，但上述第一个公开实施例中第三子胶层41的应变在其胶材应变承受范围内。
上述公开实施例中所提供的显示模组，通过对显示模组中各膜层模量、厚度的上述匹配性优化，降低了显示模组内折时其内部各膜层所受应变，减少或避免显示模组内折测试中出现胶层开胶不良和显示功能层失效不良，使该显示模组能够通过信赖性测试目标；同时还优化了显示模组折叠后形成的水滴轮廓形状。
本公开实施例还提供一种显示装置，包括上述任一实施例中的显示模组。
通过采用上述任一实施例中的显示模组，实现了对显示装置中各膜层模量、厚度的匹配性优化，降低了显示装置内折时其内部各膜层所受应变，减少或避免显示装置内折测试中出现胶层开胶不良和显示功能层失效不良，使该显示装置能够通过信赖性测试目标；同时还优化了显示装置折叠后形成的水滴轮廓形状。
本公开实施例所提供的显示装置可以为OLED面板、OLED电视、显示器、手机、导航仪等任何具有显示功能的产品或部件。
可以理解的是，以上实施方式仅仅是为了说明本公开的原理而采用的示例性实施方式，然而本公开并不局限于此。对于本领域内的普通技术人员而言，在不脱离本公开的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本公开的保护范围。
