 本发明的实施方式
下面详细描述本申请的实施方式，所述实施方式的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的组件或具有相同或类似功能的组件。本申请的说明书和权利要求书以及附图中的术语“第一”、“第二”、“第三”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应当理解，这样描述的对象在适当情况下可以互换。在本申请的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。此外，术语“包括”和“具有”以及它们的任何变形，意图在于覆盖不排它的包含。
偏光板是显示面板的重要组成部分，可以控制透过光线的偏振方向。偏光板的耐湿热性对于显示面板的显示性能有着重要的影响。但是现有技术中的偏光板的保护层通常耐湿热性较差，水汽容易对偏光板造成破坏，致使显示面板漏光或显示不均等显示缺陷。
请参照图2，图2为本申请实施例提供的一种显示面板100的截面结构示意图。显示面板100包括：
液晶盒110，液晶盒110包括第一基板111和与第一基板111对盒设置的第二基板112以及设于第一基板111和第二基板112之间的液晶层113。在本实施例中，第一基板111可以为阵列基板，第二基板112可以为彩膜基板。本申请不限定阵列基板和彩膜基板的类型。在本申请其它实施例中，阵列基板和彩膜基板可以为COA（Color Filter On Array）型的阵列基板和彩膜基板。

其中，偏光板120包括偏光子层121和第一玻璃衬底122，偏光子层121设置于第一基板111和/或第二基板112远离液晶层113的一侧，第一玻璃衬底122设置于偏光子层121远离液晶盒110一侧。
偏光子层121是偏光板120中起偏光作用的功能层，偏光子层121可以为现有技术中具有偏光功能的材料，如碘、碘的化合物或二色性染料等，本申请在此不做任何限制。
第一玻璃衬底122为柔性玻璃，柔性玻璃作为偏光子层121的保护层，具有隔绝水汽的作用，避免水汽对偏光板120的破坏，进而避免了显示面板100的漏光或显示不均等显示缺陷。
此外，本申请实施例中偏光子层121可以直接贴合在第一基板111和/或第二基板112远离液晶层113的一侧面，第一基板111和/或第二基板112也起到了对偏光子层的保护作用，节省了工艺原料和制程，同时降低了显示面板100的厚度，有利于实现显示产品的轻薄化。
在一些实施例中，偏光板120还包括第二玻璃衬底123，第二玻璃衬底123设置于偏光子层121和液晶盒110之间。在第一基板111和/或第二基板112与偏光子层121之间再设置一第二玻璃衬底123，对偏光子层121进一步提供保护，增强偏光板120的耐湿热性，进而提高显示面板100的可靠性和耐久性，延长显示产品的受用寿命。
本申请实施例的显示面板100为液晶显示面板，本申请不限定液晶显示面板的类型，其可以为垂直电场型液晶显示面板，例如扭曲向列（Twisted Nematic，TN）型液晶显示面板，多畴垂直配向（Multi-domain Vertical Alignment，MVA）型液晶显示面板，也可以是水平电场型液晶显示面板，例如边缘场开关（Fringe Field Switching，FFS）型液晶显示面板或者面内转换（In-Plane Switching，IPS）型液晶显示面板。本申请提供的显示面板100包括液晶盒110和液晶盒110两侧的偏光板120，偏光板120包括具有偏光功能的偏光子层121和第一玻璃衬底122，第一玻璃衬底122作为偏光子层121的保护层，具有隔绝水汽的作用，避免水汽对偏光板120的破坏，进而避免了显示面板100的漏光或显示不均等显示缺陷。
请参照图3，图3为本申请实施例提供的一种显示面板100的制备方法的流程示意图。显示面板100的制备方法包括以下步骤：
步骤101：对盒设置第一基板111和第二基板112，在第一基板111和第二基板112之间注入液晶，形成液晶盒110。
第一基板111为阵列基板，第二基板112为彩膜基板，在第一基板111和第二基板112之间涂布填充胶，填充胶位于框胶区内，将第一基板111和第二基板112对盒。将液晶注入至第一基板111和第二基板112之间，形成液晶层113。液晶可以为向列相、近晶相、胆甾相和蓝相液晶中的一种或两种以上。
步骤102：提供一第一玻璃衬底122，在第一玻璃衬底122一侧面制备偏光子层121，形成偏光板120。
第一玻璃衬底122为柔性玻璃，柔性玻璃作为偏光子层121的保护层，具有隔绝水汽的作用。偏光子层121是偏光板120中起偏光作用的功能层。偏光子层121可以为现有技术中具有偏光功能的材料，如碘、碘的化合物或二色性染料等，碘分子或碘离子长链有序在第一玻璃衬底122上的排列，它可以吸收平行于其排列方向的光束电场分量，只让垂直方向的光束电场分量通过，起到很好的偏光作用。二色性染料可以为蒽醌系染料和多偶氮染料，这些染料耐湿热性良好且稳定性优异。当然，在一些实施例中，偏光材料也可以为其他具有偏光功能的材料，本申请在此不做任何限制。
步骤103：将偏光板120贴合在第一基板111和/或第二基板112远离液晶层113一侧，其中，偏光子层121设置于第一基板111和/或第二基板112远离液晶层113一侧，第一玻璃衬底122设于偏光子层121远离液晶盒110一侧。
将偏光板120和液晶盒110进行贴合，具体将偏光子层121和第一基板111和/或第二基板112远离液晶层113的一侧面进行贴合，第一基板111和/或第二基板112也作为偏光子层的保护层，避免水汽对偏光板120的破坏。
本申请实施例提供的制备方法中先将发挥偏光作用的偏光子层121制备在第一玻璃衬底122上，然后再与液晶盒110进行贴合，避免了偏光子层121的制备过程中高温和挤压等操作对液晶盒110的不良影响，提高了显示产品的制备良率和可靠性。
在一些实施例中，形成偏光板120的步骤还包括：
在偏光子层121远离第一玻璃衬底122的一侧面贴合第二玻璃衬底123，形成偏光板120。
在偏光子层121的两相对侧面分别贴合第一玻璃衬底122和第二玻璃衬底123，可以进一步保护偏光子层121，提高偏光板120的耐湿热性。
在一些实施例中，将偏光板120贴合在第一基板111和/或第二基板112远离液晶层113一侧，包括：
在第二玻璃衬底123远离偏光子层121一侧贴合压敏胶层。
将第二玻璃衬底123贴合有压敏胶层的一侧与第一基板111和/或第二基板112远离液晶层113一侧贴合。
压敏胶层用于将偏光板120粘结至第一基板111和/或第二基板112上。压敏胶层可以为任何合适的压敏粘合剂，可以为溶剂型压敏粘合剂、非水乳液型压敏粘合剂等。在一个实施例中，压敏胶层可以为丙烯酸聚合物。只要压敏胶层具有合适的湿润性、粘结性和优异的光学透明度、耐水热性都可以实现本申请的目的，在此不作任何限制。
在一些实施例中，制备偏光子层121包括：
在第一玻璃衬底122的一侧面形成配向层，在配向层上附着偏光材料，形成偏光子层121。
对第一玻璃衬底122的一侧面进行配向处理，然后在经过配向处理后的侧面附着偏光材料，偏光材料在该侧面上有规则地吸附排列，形成具有偏光功能的偏光子层121。
在一些实施例中，形成配向层的方法包括摩擦配向、光配向或拉伸配向的任意一种。
摩擦配向可以通过滚轮毛刷在该侧面进行定向摩擦，形成配向槽，偏光材料吸附在配向槽内，实现有序排列。
光配向可以通过紫外光照射在该侧面上的具有感光剂的高分子聚合物，使得高分子聚合物具有配向能力，偏光材料顺着高分子聚合物排列的方向而有序排列。
拉伸配向可以通过定向拉伸处理后的树脂薄膜贴合在该侧面上，树脂薄膜可以为PVA薄膜，PVA膜的组分主要是碳氢氧等轻原子，具有高透明性和高延展性，还有良好的偏光材料吸附作用以及成膜特性等特点，是偏光板的核心原材料。定向拉伸处理后树脂薄膜内的分子定向排列，附着的偏光材料也会随着树脂薄膜内的分子的排列方向而有序排列。
在一些实施例中，附着偏光材料包括：将该侧面上形成有配向层的第一玻璃衬底浸入含有偏光材料的溶液中，偏光材料附着于配向层的表面。
在一些实施例中，在配向层远离第一玻璃衬底122一侧印刷偏光材料，偏光材料附着在配向层的表面。
偏光材料在配向层的表面有序排列，形成起偏光作用的偏光子层121。偏光材料可以为碘、碘的化合物或二色性染料等，碘分子或碘离子长链有序在第一玻璃衬底122上的排列，它可以吸收平行于其排列方向的光束电场分量，只让垂直方向的光束电场分量通过，起到很好的偏光作用。二色性染料可以为蒽醌系染料和多偶氮染料，这些染料耐湿热性良好且稳定性优异。当然，在一些实施例中，偏光材料也可以为其他具有偏光功能的材料，本申请在此不做任何限制。
在一些实施例中，制备偏光子层的步骤可以包括：通过拉伸配向形成一配向层，将所述配向层浸入含有偏光材料的溶液中，所述偏光材料附着在所述配向层上，将所述附着有偏光材料的配向层贴合在所述第一玻璃衬底一侧。
在一些实施例中，偏光材料附着在配向层后，对附着的偏光材料进行固化处理。
固化处理可以为热固化，热固化的温度可以为23℃~90℃，例如25℃、45℃、60℃、75℃以及80℃。本实施例通过对偏光材料进行热固化处理可以增强偏光材料和配向层的附着力，提升偏光板120的可靠性。
在一些实施例中，第一玻璃衬底122远离液晶盒110的一侧还贴合有功能层，功能层可以为低反射功能层、硬化功能层、抗眩光功能层、抗静电功能层及抗指纹功能层的一种或两种以上。
本申请提供的显示面板的制备方法，在第一玻璃衬底122上的一侧形成具有偏光功能的偏光子层121，将偏光子层121远离第一玻璃衬底122的一侧与液晶盒110贴合，解决了现有技术中在液晶盒上形成偏光子层过程中高温和挤压等操作对液晶盒的不良影响，提高了显示产品的制备良率和可靠性。

在一些实施例中，第一玻璃衬底或第二玻璃衬底远离偏光子层的一侧面还设置有1/4λ功能性补偿膜层，例如1/4λ波片，以形成圆偏光板，可以降低金属电极的反射。
在一些实施例中，在第一玻璃衬底或第二玻璃衬底远离偏光子层的侧面设置一层光致变色层，可以提升相应显示产品在室外阳光下显示的对比度。
在本实施例中，显示面板可以为主动发光型，也可以为被动发光型，偏光板位于OLED发光结构的一侧，该OLED发光结构可以包括阳极、阴极以及空穴注入层、空穴传输层、电子传输层和电子注入层等。具体可参考现有技术，本申请不做赘述。
本申请实施例还提供一种偏光板，包括：第一玻璃衬底，第一玻璃衬底具有第一面；偏光子层，该偏光子层具有偏光功能且设置于第一面。需要说明的是，在本实施例中，第一面可以是与液晶显示面板中的液晶盒贴合的一侧面，或与OLED显示面板中的发光结构贴合的一侧面。将偏光子层的保护层设置为柔性玻璃，柔性玻璃的隔绝水汽的能力强，可以有效避免水汽对偏光板的破坏，进而避免了显示面板的漏光或显示不均等显示缺陷。
在一些实施例中，偏光子层远离第一玻璃衬底的侧面还设置有一外保护层，在一些实施例中，外保护层可以为第二玻璃衬底。在偏光子层的两侧面都贴合上柔性玻璃，对偏光子层的提供进一步的保护，增强偏光板的耐湿热性。
在一些实施例中，外保护层远离偏光子层的一侧面还贴合有压敏胶层，以便将偏光板与液晶盒或OLED显示装置的发光面板贴合。
在一些实施例中，压敏胶层远离偏光子层的一侧还贴合有离型膜层，以防止偏光板在与液晶盒或OLED显示装置的发光面板贴合前压敏胶层被污染，有利于偏光板的大规模生产和存放。
