 本发明的实施方式
随着显示模组研发技术的发展，显示模组逐渐提出全面屏与低功耗的要求，显示模组中偏光片硬度大，不耐弯折，由于偏光片结构复杂，也影响了显示模组的发光层以上的膜层的透过率，对发光器件而言具有不小的负担，为了解决上述难题，现在产品均在开发无片材偏光片的技术，目前采用的取代偏光片的技术为在发光层上方蒸镀RGB光阻及黑框光阻用来遮挡金属反射，这种技术去除了片材偏光片，使得发光层以上的透过率可以从原来的42～45%提升到60%以上，显著的降低了功耗。但是，由于取消了偏光片层也导致外界太阳光照射到显示面板上时紫外线直接入射，对显示面板中发光材料、电子空穴传输层、注入层等造成损害，导致电激发光的发光层的发光色度及寿命等产生较大的影响。
为了解决上述技术问题，并满足柔性显示模组的弯折的需要，本申请提供了下述技术方案。
本申请实施例提供一种显示模组，具体参见图1~3，包括：
显示面板PL；
彩膜层，设置于所述显示面板PL出光面的一侧；
其中，所述彩膜层背离所述显示面板PL的一侧设置有紫外阻隔膜层50，且所述紫外阻隔膜层50覆盖所述彩膜层，所述紫外阻隔膜层50的材料包括的具有紫外线阻隔功能的光学树脂类材料，且所述紫外阻隔膜层50对于400nm以下的紫外线的透过率小于1%，所述紫外阻隔膜层50对于可见光的透过率大于92%。
具体地，如图1所示，所述显示面板PL包括LED显示面板PL或者OLED显示面板PL，所述显示面板PL包括层叠设置的衬底10、阵列基板20层、像素定义层PDL、发光层（包括同层且间隔设置的红色发光层EL-R、绿色发光层EL-G、蓝色发光层EL-B）、封装层30、触控基板层40。
具体地，所述彩膜层设置于所述显示面板PL的触控基板层上，所述彩膜层包括间隔设置的多个红色色阻CF-R、多个绿色色阻CF-G和多个蓝色色阻CF-B，以及设置于各色阻之间的黑色色阻CF-BM，且所述红色色阻CF-R对应所述红色发光层EL-R设置，所述绿色色阻CF-G对应所述绿色发光层EL-G设置，所述蓝色色阻CF-B对应所述蓝色发光层EL-B设置。
具体地，将彩膜层设置为这种阵列排布的方式，使得彩膜层可以替代偏光片，外界的光入射后直接无法透过彩膜层中的黑色色阻CF-BM，或透过红色色阻CF-R/绿色色阻CF-G/蓝色色阻CF-B后无法反射回彩膜层。这种采用彩膜层替代偏光片的技术可以提高可见光的透过率，在原有不到45%的可见光透过率基础上提升20%~30%，同时由于彩膜层的使用使得显示面板PL整体的色域提升了约5%，同时，彩膜层相对于偏光片而言硬度低，能够更好的应用于柔性显示模组。
具体地，所述彩膜层背离所述显示面板PL的一侧设置有紫外阻隔膜层50，所述紫外阻隔膜层50覆盖彩膜层，且紫外阻隔膜层50对于可见光具有92%以上的透过率，对于400nm以下的紫外线的透过率小于1%。
具体地，如图1~3所示，所述紫外阻隔膜层50的层数可以为单层或多层结构，所述紫外阻隔膜层50的材料可以包括具有紫外线阻隔功能的光学树脂类材料，例如三醋酸纤维素酯（TAC）、环烯烃聚合物（COP）、聚碳酸酯（PC）或聚甲基丙烯酸甲酯（PMMA）或压敏胶（PSA）等，紫外阻隔膜层50的总厚度在50-250um之间，采用该技术手段一方面能够起到阻隔紫外线的作用，防止在无偏光片技术中发光层受到紫外线的损害，另一方面也能够调整显示模组的中性层位置，提高柔性显示模组的大曲率弯折特性，起到保护显示装置的作用。
可以理解的是，本申请通过在彩膜层上设置紫外阻隔膜层50，紫外阻隔膜层50的材料采用光学树脂类材料，使得400nm以下的紫外线经过紫外阻隔膜层50的透过率小于1%，可见光的透过率大于92%，使得显示模组在不采用偏光片的基础上，能够降低外界太阳光照射到显示面板PL上时，紫外线直接入射对显示面板PL中发光材料、电子空穴传输层、注入层等造成的损害，提升电激发光的发光层的发光色度，有效延长发光层的使用寿命。
在一实施例中，所述紫外阻隔膜层50的材料包括三醋酸纤维素酯、环烯烃聚合物、聚碳酸酯或聚甲基丙烯酸甲酯。
具体地，所述紫外阻隔膜层50的材料主要为光学树脂类材料，上述材料三醋酸纤维素酯（TAC）、环烯烃聚合物（COP）、聚碳酸酯（PC）或聚甲基丙烯酸甲酯（PMMA）均具有阻隔部分紫外线的功能，且其在50~250um的厚度范围内具有合适的弹性模量，能够适应柔性显示模组的弯折，其中上述材料中还可以添加紫外吸收剂以使得紫外阻隔膜层50的材料的紫外线（400nm以下波段）透过率在1%以下。
具体地，所述紫外吸收剂可以包括苯并三氮唑类化合物、邻羟基二苯甲酮类化合物、水杨酸酯类化合物、三嗪类化合物或取代丙烯腈类化合物。
可以理解的是，通过采用上述光学树脂类材料的原因是，该光学树脂类材料自身具有良好的弹性模量，且具备一定的紫外线阻隔能力，例如，PMMA能有效滤除波长小于300nm的紫外光，但300nm至400nm之间滤除效果较差，通过添加能够阻隔300nm~400nm波段的紫外线的紫外吸收剂就能够使得PMMA有效阻隔400nm以下的紫外线。
同时，由于紫外吸收剂添加量少，对于可见光的透过率影响相对于常规的光学树脂类材料更小，可见光透过率相对更高。
在一实施例中，如图2所示，所述紫外阻隔膜层50包括至少一紫外线阻隔单元层500，所述紫外线阻隔单元层500包括层叠设置的紫外阻隔基材层501和紫外阻隔粘合层502，所述紫外阻隔粘合层502设置于所述紫外阻隔基材层501靠近所述彩膜层的一侧。
具体地，所述紫外阻隔膜层50可以包括一紫外线阻隔单元层500，可以包括两层紫外线阻隔单元层500，也可以包括三层紫外线阻隔单元层500，具体的层数不作限制。
具体地，所述紫外阻隔膜层50的总厚度在50~250um，弹性模量范围在1~9GPa内，即满足本申请的要求，当具有两层以上的紫外线阻隔单元层500时，各紫外线阻隔单元层500重叠设置。
具体地，所述紫外线阻隔单元层500包括层叠设置的紫外阻隔基材层501和紫外阻隔粘合层502，所述紫外阻隔基材层501的材料包括：TAC、COP、PC、PMMA等，所述紫外阻隔粘合层502的材料包括亚克力压敏胶或丙烯酸酯压敏胶。
具体地，所述紫外阻隔基材层501中可以设置紫外线阻隔粒子，所述紫外线阻隔粒子包括二氧化钛(TiO 2)、氧化锌(ZnO)、氧化铁(Fe 2O 3)、氧化锆(ZrO 2)、二氧化硅(SiO 2)、氧化锰(MnO)、氧化铝(Al 2O 3)、氧化铈(CeO 2)、云母、硅石、滑石和高岭土，其平均粒径为10~3000nm，具体可以为10~2000nm，具体可以为20~500nm。
可以理解的是，将紫外阻隔膜层50设置为包括至少一紫外线阻隔单元层500，所述紫外线阻隔单元层500包括紫外阻隔基材层501和紫外阻隔粘合层502，能够有效提高单一的膜层阻隔紫外线的能力，有效阻隔400nm波段以下的紫外线，紫外阻隔基材采用TAC、COP等光学树脂类材料，不仅透过率高达92%以上，也不会对光线造成偏振态的改变；
其次，通过在紫外阻隔膜层50内设置紫外阻隔粘合层502使得产品不需要经过涂布等的步骤，在显示模组组装时，能够直接粘合至显示面板PL上，提高显示模组的生产效率，由于紫外阻隔粘合层502作为胶材与紫外阻隔基材层501具有不同的弹性模量，能够在柔性显示模组弯折时，提供一定的缓冲作用，防止膜层之间由于弯折的剪切力过大发生膜层裂片的问题。
在一实施例中，所述紫外阻隔膜层50的厚度范围为50~250um，所述紫外阻隔膜层50的弹性模量范围为1~9GPa。
需要说明的是，中性层是指使材料在弯折时，该层不受到拉应力也不受到压应力的位置，该层的位置受到整体显示模组结构及各层的厚度及弹性模量的影响。
可以理解的是，通过限制紫外阻隔膜层50的厚度，并选择合适的弹性模量范围，使得可以通过调整紫外阻隔膜层50的厚度调整中性层的位置，以达到将中性层调整到显示模组中最脆弱的膜层上，降低显示面板PL中最脆弱的膜层裂片的可能性，更好的保护显示模组。
在一实施例中，所述紫外阻隔膜层50结构包括一所述紫外线阻隔单元层500，所述紫外阻隔基材层501的厚度为20~100um，所述紫外阻隔粘合层502的厚度为15~50um。
具体地，所述紫外隔离基材层的厚度范围在20~100um内，例如，厚度可以为20um，30um，40um，45um，50um，70um，100um等。
具体地，所述紫外阻隔粘合层502的厚度范围在15~50um内，例如，厚度可以为15um，20um，25um，30um，35um，40um，50um等。
可以理解的是，将紫外阻隔基材层501和紫外阻隔粘合层502的厚度进行限制，使其在合适的范围内，防止紫外隔离基材层和/或紫外阻隔粘合层502过厚会影响模组整体的厚度，紫外隔离基材层和/或紫外阻隔粘合层502过薄无法起到调整中性层的作用。
在一实施例中，如图3所示，所述紫外阻隔膜层50包括至少两所述紫外线阻隔单元层500，各所述紫外线阻隔单元层500层叠设置。
具体地，两层所述紫外线阻隔单元层500可以直接重叠贴设，利用相邻的两紫外隔离基材层之间的紫外阻隔粘合层502进行粘合。
具体地，如图4所示，与所述紫外阻隔粘合层502相邻的紫外隔离基材层上可以设置第一凹槽和/或第一凸起，对应的所述紫外阻隔粘合层502上设置有与所述第一凹槽和/或所述第一凸起相匹配的第二凸起和/或所述第一凸起，以使所述紫外阻隔膜层50之间的各膜层贴合更紧密，也能够更好的起到缓冲作用。
可以理解的是，当显示模组为动态折叠显示模组时，提供多层紫外阻隔粘合层502以缓冲弯折时候的剪切应力，弯折过程中，膜层与膜层之间会发生相对的剪切移动，如果没有紫外阻隔粘合层502作为胶材膜层进行膜层与膜层之间的连接，会导致膜层之间因为弯折的剪切力发生裂片，因此，采用多层紫外线阻隔单元层500膜层与膜层之间需要模量低的可以蠕变的胶材来缓冲。
在一实施例中，所述紫外阻隔膜层50包括两所述紫外线阻隔单元层500，所述紫外线阻隔单元层500中的所述紫外阻隔基材层501的厚度为20~40um，所述紫外阻隔粘合层502的厚度为15~50um。
可以理解的是，将紫外阻隔基材层501和紫外阻隔粘合层502的厚度进行限制，使其在合适的范围内，防止紫外隔离基材层和/或紫外阻隔粘合层502过厚会影响模组整体的厚度，紫外隔离基材层和/或紫外阻隔粘合层502过薄无法起到调整中性层的作用。
在一实施例中，所述紫外阻隔膜层50背离所述彩膜层的一面设置有粘胶层60。
具体地，如图1所示，所述粘胶层上还覆盖有盖板层70。
具体地，所述粘胶层60的材料可以为光敏胶，所述粘胶层60的厚度为50~150nm。
可以理解的是，在所述紫外阻隔膜层50自带一层粘合层的基础上，通过在紫外阻隔膜层50背离所述彩膜层的一面设置有粘胶层60，能够减少显示模组在组装拼合时的一次贴合制程，提高显示模组的组装效率，减少贴合步骤。
在一实施例中，所述紫外阻隔粘合层502的材质包括压敏胶，所述粘胶层60的材质包括光敏胶。
具体地，所述压敏胶可以为亚克力压敏胶或丙烯酸酯类压敏胶，所述光敏胶包括环氧类光敏胶、聚酯类光敏胶或聚氨酯类光敏胶。
在一实施例中，所述紫外阻隔膜层50中所述紫外阻隔基材层501和/或所述紫外阻隔粘合层502内设置有紫外线阻隔粒子。
具体地，所述紫外线阻隔粒子包括二氧化钛(TiO 2)、氧化锌(ZnO)、氧化铁(Fe 2O 3)、氧化锆(ZrO 2)、二氧化硅(SiO 2)、氧化锰(MnO)、氧化铝(Al 2O 3)、氧化铈(CeO 2)、云母、硅石、滑石和高岭土，其平均粒径可以为10~3000nm，具体可以为10~2000nm，具体可以为20~500nm。
此外，本申请实施例还提供一种移动终端，包括上述任一项实施例所述的显示模组及终端主体，所述终端主体与所述显示模组组合为一体。
综上，本申请通过在彩膜层上设置紫外阻隔膜层50，紫外阻隔膜层50采用光学树脂类材料，使得400nm以下的紫外线经过紫外阻隔膜层50的透过率小于1%，可见光的透过率大于92%，使得显示模组在不采用偏光片的基础上，够降低外界太阳光照射到显示面板PL上时，紫外线直接入射对显示面板PL中发光材料、电子空穴传输层、注入层等的损害，提升电激发光的发光层的发光色度，有效延长发光层的使用寿命；其次，采用光学树脂材料作为紫外阻隔膜层50的主要材料使得显示模组的弯折性能更好，能够适应柔性显示模组的开发，后续通过限制紫外阻隔膜层50的厚度，并选择合适的弹性模量范围，使得可以通过调整紫外阻隔膜层50的厚度调整中性层的位置，以达到将中性层调整到显示模组中最脆弱的膜层上，降低显示面板PL中最脆弱的膜层裂片的可能性，更好的保护显示模组。
可以理解的是，对本领域普通技术人员来说，可以根据本申请的技术方案及其发明构思加以等同替换或改变，而所有这些改变或替换都应属于本申请所附的权利要求的保护范围。
