 附图说明
为了更清楚地说明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单介绍，显而易见地，下面描述中的附图仅仅是发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本申请实施例一显示模组的膜层结构图；
图2为本申请实施例二显示模组的膜层结构图；
图3为本申请实施例三显示模组的膜层结构图；
图4为本申请实施例四显示模组的膜层结构图；
图5为本申请实施例五显示模组的膜层结构图。
 本发明的最佳实施方式
以下各实施例的说明是参考附加的图示，用以例示本申请可用以实施的特定实施例。本申请所提到的方向用语，例如[上]、[下]、[前]、[后]、[左]、[右]、[内]、[外]、[侧面]等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本申请，而非用以限制本申请。在图中，结构相似的单元是用以相同标号表示。
图1为本申请实施例一显示模组的膜层结构图，其包括显示面板10及位于所述显示面板10上的偏光片层，所述偏光片层包括第一相位层20、位于所述第一相位层20上的线偏光层30及位于所述线偏光层30上的第二相位层40。
进一步的，所述显示面板可以为但不限定于液晶显示面板或OLED显示面板，下面实施例将以OLED显示面板为例进行说明；
OLED显示面板包括阵列基板、位于所述阵列基板上的发光器件层及位于所述发光器件层上的薄膜封装层；可以理解的，所述阵列基板可以为但不限定于柔性基板，优选的，所述柔性材料可以为聚酰亚胺薄膜。
在本申请的显示模组中，所述第一相位层20及所述第二相位层40为λ/4波片，所述λ/4波片用于将线偏振光转变为圆偏振光，或将圆偏振光转变为线偏振光。
进一步的，所述线偏光层30也可以被称为PVA（聚乙烯醇）层，所述线偏光层30为所述偏光片层的核心部分，主要用于吸收自然光中一个偏振态的光线，透过另一个偏振态光线，即获得偏振光；优选的，所述线偏光层30的厚度一般设置在20um。
可以理解的，外界自然光经第二相位层40直接进入显示模组内；其中，由于只有线偏振光经过相位层时，相位才会发生相应的变化，即变成圆偏振光；
本实施例中，当自然光经过第二相位层40时，自然光不会发生相应变化，随之进入线偏光层30后将变成第一线偏振光，所述第一线偏振光经过所述第一相位层20时，将转变成第一圆偏振光；而由于发光器件层表面金属层（即阴极层）的反射作用，所述第一圆偏振光将重新进入所述第一相位层20，即所述第一圆偏振光将被转换成第二线偏振光；
可以理解的，所述第一相位层20为λ/4波片，因此两次经过所述第一相位层20，所述第一线偏振光与所述第二线偏振光的相位差为λ/2，即所述第一线偏振光与所述第二线偏振光偏振方向相互垂直，所述第二偏振光不能透过线偏光层30而被阻挡；
同理，所述发光器件层发出的光线（也可理解为自然光），经过所述第一相位层20时，自然光不会发生相应变化，随之进入线偏光层30后将变成线偏振光，所述线偏振光经过所述第二相位层40时，将转变成圆偏振光，使得佩戴太阳眼镜的用户在任意角度下能对该OLED显示器可视；
另外，本实施例中的所述偏光片层还包括位于所述显示面板10与所述第一相位层20之间的第一粘接层60；
具体的，第一相位层20、第二相位层40同时起到相位层的作用、及线偏光层的支撑/保护层作用；并且，本实施例中的所述偏光片层相比现有偏光片层厚度更小，降低了显示模组的膜层厚度。
图2为本申请实施例二显示模组的膜层结构图，与实施例一相比，本申请所述显示模组还包括第三相位层50，所述第三相位层50位于所述第一相位层20与所述线偏光层30之间；其中，所述第三相位层50为λ/2波片，所述λ/2波片用于将线偏振光的偏振状态改变为预设的另一方向，或者将圆偏振光的的旋向改变为相反方向；
可以理解的，外界自然光进入本实施例中的显示模组时，经过所述线偏振层形成第一线偏振光，再经过两次所述第一相位层20、两次所述第三相位层50后形成第二线偏振光，所述第一线偏振光与所述第二线偏振光相比，相位差为3λ/2，所述第一线偏振光与所述第二线偏振光偏振方向相互垂直，所述第二偏振光不能透过线偏光层30而被阻挡；
同理，所述发光器件层发出的光线（也可理解为自然光），经过所述第一相位层20以及所述第三相位层50时，自然光不会发生相应变化，随之进入线偏光层30后将变成线偏振光，所述线偏振光经过所述第一相位层20时，将转变成圆偏振光，使得佩戴太阳眼镜的用户在任意角度下能对该OLED显示器可视。
另外，在本申请的显示模组中，所述显示模组还包括至少一粘接层，所述粘接层紧邻所述第一相位层20或/和所述第二相位层40设置；
可以理解的，所述粘接层也可被称为PSA（压敏胶）层，即一种靠压力作用实现对被粘接物体表面黏合的材料，它在偏光片中的作用为确保偏光片能够可靠地粘贴在封装层表面；
优选的，所述粘结层的厚度一般设置为20um。
如图3所示，在实施例一及实施例二的基础上，实施例三中的所述粘接层还可以包括第二粘接层70，所述第二粘接层70位于所述第一相位层20与所述第三相位层50之间；
可以理解的，实施例三的工作原理与实施例一、及实施例二相同，此处不再一一赘述。
图4为本申请实施例四显示模组的膜层结构图，在实施例三的基础上，所述粘接层包括第一粘接层60、第二粘接层70及第三粘结层100；其中，所述第一粘接层60位于所述第一相位层20与所述显示面板10之间，所述第二粘接层70位于所述第一相位层20与所述第三相位层50之间，所述第三粘结层100位于所述第二相位层40与所述线偏光层30之间；
可以理解的，实施例四的工作原理与实施例一至实施例三相同，此处不再一一赘述。
图5所示为本申请实施例五显示模组的膜层结构图，与实施例不同之处在于：
在本实施例中所述显示模组还包括至少一支撑层，所述支撑层紧邻所述线偏光层30设置；所述支撑层可以称为TAC（三醋酸纤维素）层，所述支撑层在偏光片中主要起到支撑和保护下层的PVA层的作用，即一般在线偏光层30的两侧设置所述支撑层；
优选的，所述TAC层的厚度一般设置在40um~60um；
进一步的，如图5所示，所述支撑层包括第一支撑层80和第二支撑层90；所述第一支撑层80位于所述第二粘接层70与所述线偏光层30之间，所述第二支撑层90位于所述第三粘接层100与所述线偏光层30之间。
在本申请的实施例一至实施例五中，所述第一相位层20、所述第二相位层40及所述第三相位层50可以是通过拉伸由聚碳酸酯、聚乙烯醇、聚苯乙烯、聚甲基丙烯酸甲酯、聚丙烯、聚烯烃、多芳基化合物和聚酰胺中的至少一种聚合物制成的膜所形成的双折射膜、液晶聚合物的取向膜或用液晶聚合物的取向膜支撑的膜。
进一步的，所述第二相位层40的表面可以做硬化或防眩处理。
本申请还提出了一种电子装置，所述电子装置包括上述显示面板。可以理解的，所述电子装置包括但不限定于手机、平板电脑、计算机显示器、游戏机、电视机、显示屏幕、可穿戴设备及其他具有显示功能的生活电器或家用电器等。
本申请提出了一种显示模组及电子装置，所述显示模组包括显示面板及位于所述显示面板上的偏光片层，所述偏光片层包括：第一相位层；位于所述第一相位层上线偏光层；位于所述线偏光层上的第二相位层；其中，所述第一相位层及所述第二相位层为λ/4波片，所述λ/4波片的补偿值为对应波长的1/4。本申请通过在线偏光层两侧设置λ/4波片的相位层，使得显示面板发出的光线经过第一相位层、线偏光层以及第二相位层后变成圆偏振光，使得佩戴太阳眼镜的用户在任意角度下能对OLED显示器的可视。
综上所述，虽然本申请已以优选实施例揭露如上，但上述优选实施例并非用以限制本申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为准。
