具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
目前，反射式显示面板在背光源的位置设置反光金属层，反射外界的环境光进行显示，然后搭配使用由PVA、1/2λ波片、1/4λ波片结合构成的偏光片。但由于光具有色散性，1/2λ波片和1/4λ波片不能将所有可见光旋转90°，暗态时仍有部分光出射，导致反射式显示面板的对比度低(一般为几十)，且1/2λ波片和1/4λ波片的角度设计复杂，结构多变，偏光片厂商对应困难，偏光片成本较高。
图1是本申请实施例提供的一种显示面板的结构示意图。参考图1可以看出，该显示面板10可以包括：液晶盒101，第一偏光组件102以及第二偏光组件103。液晶盒101可以包括相对设置的第一基板1011和第二基板1012，以及位于第一基板1011和第二基板1012之间的液晶层1013。
第一偏光组件102位于第一基板1011远离液晶层1013的一侧。该第一偏光组件102至少包括第一偏光层1021，该第一偏光层1021可以具有第一透光轴，第一偏光组件102用于生成偏振方向与第一透光轴平行的偏振光(该偏振光可以为线偏振光)。例如，外界的环境光线(外界的环境光线也可称为自然光) 或者位于显示面板10的显示侧的第二光源组件发出的光线照射至该第一偏光组件102之后，该第一偏光组件102可以将光线转换为偏振方向与第一透光轴平行的偏振光。其中，显示面板10的显示侧为液晶盒101靠近第一偏光组件102的一侧。
第二偏光组件103可以位于第二基板1012远离液晶层1013的一侧。该第二偏光组件103至少包括透反层1031和光吸收层1032，该透反层1031相对于光吸收层1032靠近液晶盒101。该透反层1031具有第二透光轴，用于透射偏振方向与第二透光轴平行的偏振光，且用于反射偏振方向与第二透光轴垂直的偏振光。光吸收层1032用于吸收被透反层1031透射的偏振光。
第一偏光组件102将光线转换为偏振方向与第一透光轴平行的偏振光之后，该偏振光可以经由液晶盒101照射至第二偏光组件103。其中，偏振光经过液晶盒101之后，其偏振方向可能发生变化也可能未发生变化(其中，经过液晶盒101之后的偏振光可以为线偏振光，椭圆偏光或圆偏光)。无论是否发生变化，若照射至第二偏光组件103的透反层1031的偏振光的偏振方向与透反层1031的第二透光轴平行，就可以通过透反层1031透射，进而照射至光吸收层1032而被光吸收层1032吸收，呈暗态；若照射至第二偏光组件103的透反层1031的偏振光的偏振方向与透反层1031的第二透光轴不平行(例如垂直)，就会被该透反层1031反射，光线能够从显示面板的显示侧出射，呈亮态。
在本申请实施例中，透反层1031可以实现透射光线以及反射光线的作用。比如该透反层1031可以透射偏振方向与第二透光轴平行的光线，且可以反射偏振方向与第二透光轴垂直的光线。可选的，该透反层1031可以为半透半反层，即可以实现照射至透反层1031的光线中的一半光线被透射，一半光线被反射。
综上所述，本申请实施例提供了一种显示面板，该显示面板包括液晶盒，第一偏光组件以及第二偏光组件。该第一偏光组件至少包括具有第一透光轴的第一偏光层，用于生成偏振方向与第一透光轴平行的偏振光。第二偏光组件至少包括透反层和光吸收层。透反层具有第二透光轴，用于透射偏振方向与第二透光轴平行的偏振光，且用于反射偏振方向与第二透光轴垂直的偏振光。光吸收层用于吸收透反层透射的偏振光。本申请实施例通过结合第一偏光组件中的第一偏光层，以及第二偏光组件中的透反层和光吸收层来实现反射式显示面板，能够提高显示面板的对比度，且可以批量制备，成本较低。
在本申请实施例中，第一偏光组件102相对于第二偏光组件103更靠近入光侧。入光侧的光线包括外界的环境光线，和/或，显示面板10包括的第二光源组件发出的光线。该第二光源组件位于显示面板10的显示侧，即位于第一偏光组件102远离液晶盒101的一侧。
其中，在外界的环境光线充足的情况下，入光侧的光线可以仅包括外界的环境光线，第二光源组件可以无需发光。在外界的环境光线不足的情况下，第二光源组件可以发光以实现补光作用。此种情况下，入光侧的光线可以包括第二光源组件发出的光线。
可选的，第一偏光层1021的材料可以为聚乙烯醇(polyvinyl alcohol，PVA)加碘离子，该第一偏光层1021可以称为第一PVA层。高级偏振片(advanced polarizer film，APF)在常规的液晶显示产品中主要起到增亮作用，本申请可以利用其反射功能将其用作本申请实施例中的透反层1031。该透反层1031可以称为APF层。
可选的，第一基板1011和第二基板1012可以为玻璃基板或石英基板，本申请实施例对此不做限定。
图2是本申请实施例提供的另一种显示面板的结构示意图。图3是本申请实施例提供的一种第一偏光组件的结构示意图。结合图2和图3可以看出，该第一偏光组件102还可以包括：第一粘接层1022，第一保护层1023以及第二保护层1024。该第一粘接层1022可以位于第一偏光层1021靠近液晶盒101的一侧，第一保护层1023可以位于第一粘接层1022和第一偏光层1021之前，第二保护层1024可以位于第一偏光层1021远离液晶盒101的一侧。也即是，第一偏光组件102中第一粘接层1022，第一偏光层1021，第一保护层1023以及第二保护层1024沿远离液晶盒101的方向依次层叠。其中，第一粘接层1022可以用于将第一保护层1023与第一基板1011粘接，第一保护层1023和第二保护层1024分别用于保护第一偏光层1021的两个表面。
在本申请实施例中，作为第一种可选的实现方式，光吸收层1032可以为第二偏光层。该第二偏光层1032具有吸收轴和第三透光轴。吸收轴和第二透光轴平行，第三透光轴和第二透光轴垂直。其中，该第二偏光层1032可以称为第二PVA层。
图4是本申请实施例提供的一种第二偏光组件的结构示意图。结合图2和 图4，该第二偏光组件103还可以包括：第二粘接层1033，第三粘接层1034，第三保护层1035以及第四保护层1036。第二粘接层1033位于透反层1031靠近液晶盒101的一侧。第三粘接层1034位于透反层1031和第二偏光层1032之间。第三保护层1035位于第三粘接层1034和第二偏光层1032之间。第四保护层1036位于第二偏光层1032远离液晶盒101的一侧。也即是，如果光吸收层1032为第二偏光层1032，则第二偏光组件103中的第二粘接层1033，透反层1031，第三粘接层1034，第三保护层1035，第二偏光层1032，第四保护层1036沿远离液晶盒101的方向依次层叠。其中，第二粘接层1033用于将透反层1031和第二基板1012粘接，第三粘接层1034用于将透反层1031和第三保护层1035粘接，第三保护层1035和第四保护层1036分别用于保护第二偏光层1032的两个表面。
在本申请实施例中，各个粘接层(第一粘接层1022，第二粘接层1033和第三粘接层1034)的材料可以包括压敏胶(pressure sensitive adhesive，PSA)，其主要功能是将两侧的膜层粘接。各个保护层(第一保护层1023，第二保护层1024，第三保护层1035以及第四保护层1036)的材料可以包括三醋酸纤维素(triacetyl cellulose，TAC)，其主要功能是保护偏光层的表面。
其中，各个保护层可以采用不同的处理方式进行处理。其中，处理方式包括普通(normal)处理(即无特殊处理)以及特殊处理。特殊处理包括硬化(hardcoat，HC)处理以及0位相差延迟处理。
硬化(hardcoat，HC)处理通常适用于表层的保护层。例如，第二保护层1024可以采用HC处理，该第二保护层1024可以称为HC-TAC层。
0位相差延迟处理的保护层可以具有较好的视角、对比度及色偏。因此光路经过的保护层可以采用0位相差延迟处理，例如第一保护层1023和第三保护层1035可以采用0位相差延迟处理，该第二保护层1024和第三保护层1035可以称为0-TAC层。或者，第一保护层1023和第三保护层1035也可以采用normal处理，该第二保护层1024和第三保护层1035可以称为TAC层。
对于光路不经过只需起到保护作用的保护层可以采用normal处理，如第四保护层1036可以采用normal处理，该第四保护层1036可以称为TAC层。或者，该第四保护层1036也可以采用0位相差延迟处理，即第四保护层1036也可以称为0-TAC层。
图3示出的第一偏光组件102还包括第一保护膜(protect film)和第一离型膜(release film)，该第一保护膜和第一离型膜的作用是保护两者之间的膜层。图4出的第二偏光组件103还包括第二保护膜和第二离型膜，第二保护膜和第二离型膜的作用是保护两者之间的膜层。图3和图4分别示出的是与液晶盒101贴合之前的第一偏光组件102和第二偏光组件103。
另外，将第一偏光组件102与液晶盒101贴合时，先将第一离型膜去除，以使得第一粘接层1022与液晶盒101的第一基板1011粘接。将第二偏光组件103与液晶盒101贴合时，先将第二离型膜去除，以使得第二粘接层1033与液晶盒101的第二基板1012粘接。之后将显示面板组装成显示模组时，再将第一保护膜和第二保护膜去除。也即是，最终生产的产品中不包括第一保护膜，第一离型膜，第二保护膜和第二离型膜，这也是图2示出的显示面板10中未示出第一保护膜，第一离型膜，第二保护膜和第二离型膜的主要原因。
需要说明的是，相关技术中，反射式的液晶显示面板包括的第二偏光组件的APF层相对于第二PVA层远离液晶盒。液晶显示面板的光线通常来自于APF层远离液晶盒的一侧的背光光源组件。背光光源组件发出的光线需要先透过APF层，且透过APF层的光线进入到第二PVA层，光线透过第二PVA层之后经过液晶盒，经过液晶盒的光线光线再通过第一偏光组件的第一PVA层。也即是，相关技术中，能够出射的光线一定是能够被第二PVA层和APF层透过的光线。
而在本申请实施例中，光线主要来自于显示面板的显示侧的环境光线，或者位于显示面板的显示侧的第二光源组件发出的光线。其中，第二偏光组件的APF层相对于第二PVA层靠近液晶盒。光线先经过第一偏光组件102的第一PVA层和液晶盒101，再到达第二偏光组件103的APF层。APF层会反射偏振方向与第二透光轴垂直的偏振光，被反射的偏振光再次经过液晶盒101与第一偏光组件102的第一PVA层。也即是，出射的光线一定是被APF反射的光线。本申请实施例中第二偏光组件103的APF层和第二PVA层的层叠关系，以及光路设计均与相关技术不同。
其中，为了方便理解本申请实施例与相关技术的区别，相关技术中的相关描述参照了本申请实施例中的相关描述，例如相关技术中也采用了第一偏光组件，第一PVA层，第二偏光组件，APF层，以及第二PVA层等描述。实际上， 相关技术中可能不包括这些组件或膜层。
在本申请实施例中，液晶盒101可以为扭曲向列型(twisted nematic，TN)液晶盒，平面转换型(IN-plane switching，IPS)液晶盒，或者多象限垂直配向型(vertical alignment，VA)液晶盒。另外，高级超维场转换技术(advanced super dimension switch，ADS)也可以采用平面转换型液晶盒，ADS和IPS的区别在于电极设计的不同。下述针对IPS液晶盒的描述同样适用于ADS。
其中，对于TN液晶盒101，其液晶层1013靠近第一基板1011的液晶分子的取向，与液晶层1013靠近第二基板1012的液晶分子的取向垂直。在不加电的情况下，偏振光通过液晶盒101之后其偏振方向会偏转90°(度)。对于IPS液晶盒101，其液晶层1013靠近第一基板1011的液晶分子的取向，与液晶层1013靠近第二基板1012的液晶分子的取向平行。在不加电的情况下，偏振光通过液晶盒101之后其偏振方向不变。对于VA液晶盒101，其液晶层1013靠近第一基板1011的液晶分子的取向，与液晶层1013靠近第二基板1012的液晶分子的取向平行。在不加电的情况下，偏振光通过液晶盒101之后其偏振方向不变。
第一种情况，以图2所示的显示面板为例，若液晶盒101为TN液晶盒，且显示面板为全反射常白模式，则液晶分子的取向以及透光轴的设计如下：第一偏光层1021的第一透光轴与TN液晶盒101靠近第一基板1011的液晶分子的取向方向平行，透反层1031的第二透光轴与TN液晶盒101靠近第二基板1012的液晶分子的取向垂直，第二偏光层1032的吸收轴与透反层1031的第二透光轴平行(第二偏光层1032的第三透光轴与透反层1031的第二透光轴垂直)。其中，全反射常白模式是指：不加电的情况下，光线能够出射，呈亮态；加电的情况下，光线不能出射，呈暗态。
参考图5，在液晶层1013未加电的情况下，光线(外界的环境光线或者位于显示面板的显示侧的第二光源组件发出的光线)入射至第一偏光组件102的第一偏光层1021后，生成偏振方向与第一透光轴平行的第一偏振光(线偏振光)。第一偏振光经过TN液晶盒101之后偏振方向旋转90°，得到第二偏振光(线偏振光)。该第二偏振光的偏振方向与透反层1031的第二透光轴垂直，该第二偏振光被透反层1031反射回TN液晶盒101。该第二偏振光经过TN液晶盒101后偏振方向旋转90°，得到第三偏振光(线偏振光)。该第三偏振光的偏振方 向与第一偏振光的偏振方向平行，即该第三偏振光的偏振方向与第一偏光层1021的第一透光轴平行。该第三偏振光能够通过第一偏光组件102出射，实现常白模式，即呈亮态。
参考图6，在液晶层1013加电的情况下，光线(外界的环境光线或者位于置在显示面板的显示侧的第二光源组件发出的光线)入射至第一偏光组件102的第一偏光层1021后，生成偏振方向与第一透光轴平行的第一偏振光(线偏振光)。第一偏振光经过TN液晶盒101之后偏振方向保持不变，即仍为第一偏振光。由于第一偏振光的偏振方向与透反层1031的第二透光轴平行，因此该第一偏振光可以透过透反层1031照射至第二偏光层1032。第二偏光层1032的吸收轴与透反层1031的第二透光轴平行，因此从透反层1031透过的第一偏振光可以被第二偏光层1032吸收，无光线出射，光线无法返回进入人眼，实现黑态，即呈暗态。
在该第一种情况下，实际上仅需保证第一偏光层1021的第一透光轴与透反层1031的第二透光轴平行即可实现上述TN液晶盒101的常白模式。TN液晶盒101中基板和液晶分子的初始取向可以为任意角度。
第二种情况，以图2所示的显示面板为例，若液晶盒101为TN液晶盒，且显示面板为全反射常黑模式，则液晶分子的取向以及透光轴的设计如下：第一偏光层1021的第一透光轴与TN液晶盒101靠近第一基板1011的液晶分子的取向方向平行，透反层1031的第二透光轴与TN液晶盒101靠近第二基板1012的液晶分子的取向方向平行，第二偏光层1032的吸收轴与透反层1031的第二透光轴平行(第二偏光层1032的第三透光轴与透反层1031的第二透光轴垂直)。其中，全反射常黑模式是指：不加电的情况下，光线不能出射，呈暗态；加电的情况下，光线能够出射，呈亮态。
参考图7，在液晶层1013未加电的情况下，光线(外界的环境光线或者位于显示面板的显示侧的第二光源组件发出的光线)入射至第一偏光组件102的第一偏光层1021后，生成偏振方向与第一透光轴平行的第一偏振光(线偏振光)。第一偏振光经过TN液晶盒101之后偏振方向旋转90°，得到第二偏振光(线偏振光)。该第二偏振光的偏振方向与透反层1031的第二透光轴平行，因此该第二偏振光可以透过透反层1031照射至第二偏光层1032。第二偏光层1032的吸收轴与透反层1031的第二透光轴平行，因此从透反层1031透过的第二偏振 光可以被第二偏光层1032吸收，无光线出射，光线无法返回进入人眼，实现黑态，即呈暗态。
参考图8，在液晶层1013加电的情况下，光线(外界的环境光线或者位于显示面板的显示侧的第二光源组件发出的光线)入射至第一偏光组件102的第一偏光层1021后，生成偏振方向与第一透光轴平行的第一偏振光(线偏振光)。第一偏振光经过TN液晶盒101之后偏振方向保持不变，即仍为第一偏振光。由于第一偏振光的偏振方向与透反层1031的第二透光轴垂直，因此该第一偏振光被透反层1031反射回TN液晶盒101。该第一偏振光经过TN液晶盒101后方向依然保持不变，即与第一偏光层1021的第一透光轴平行。该第一偏振光能够通过第一偏光组件102出射，实现白态，即呈亮态。
在该第二种情况下，实际上仅需保证第一偏光层1021的第一透光轴与透反层1031的第二透光轴垂直即可实现上述TN液晶盒101的常黑模式。TN液晶盒101中基板和液晶分子的初始取向可以为任意角度。
其中，对于TN液晶盒101，将第一种情况的常白模式中透反层1031和第二偏光层1032同时旋转90°即可得到对于第二种情况的常黑模式。
第三种情况，以图2所示的显示面板为例，若液晶盒101为IPS型液晶盒101，且显示面板为全反射常白模式，则液晶分子的取向以及透光轴的设计如下：第一偏光层1021的第一透光轴与IPS液晶盒101靠近第一基板1011的液晶分子的取向方向平行，透反层1031的第二透光轴与IPS液晶盒101靠近第二基板1012的液晶分子的取向方向垂直，第二偏光层1032的吸收轴与透反层1031的第二透光轴平行(第二偏光层1032的第三透光轴与透反层1031的第二透光轴垂直)。
参考图9，在液晶层1013未加电的情况下，光线(外界的环境光线或者位于显示面板的显示侧的第二光源组件发出的光线)入射至第一偏光组件102的第一偏光层1021后，生成偏振方向与第一透光轴平行的第一偏振光(线偏振光)。该第一偏振光经过IPS液晶盒101之后变化为第二偏振光(由于不加电的情况下，液晶盒不起作用，因此第二偏振光与第一偏振光的偏振方向相同)。该第二偏振光的偏振方向与透反层1031的第二透光轴垂直，因此该第二偏振光的被透反层1031反射回IPS液晶盒101。该第二偏振光经过IPS液晶盒101后偏振方向依然保持不变，即与第一偏光层1021的第一透光轴平行。该第二偏振光能够通过第一偏光组件102出射，实现常白模式，即呈亮态。
参考图10，在液晶层1013加电的情况下，光线(外界的环境光线或者位于显示面板的显示侧的第二光源组件发出的光线)入射至第一偏光组件102的第一偏光层1021之后，生成偏振方向与第一透光轴平行的第一偏振光(线偏振光)。第一偏振光经过IPS液晶盒101之后变化为第二偏振光(椭圆偏光)，该第二偏振光的有效偏振光(椭圆偏光可以分解为互相垂直的两个线偏振光的偏振分量，较大分量的线偏振光定义为有效偏振光，较大分量的线偏振光的偏振方向为有效偏振光的偏振方向)的偏振方向与透反层1031的第二透光轴平行，因此该第二偏振光的有效偏振光可以透过透反层1031照射至第二偏光层1032。第二偏光层1032的吸收轴与透反层1031的第二透光轴平行，因此从透反层1031透过的第二偏振光的有效偏振光可以被第二偏光层1032吸收，无光线出射，光线无法返回进入人眼，实现黑态，即呈暗态。
在该第三种情况下，实际上仅需保证第一偏光层1021的第一透光轴与透反层1031的第二透光轴垂直即可实现上述IPS液晶盒101的常白模式。IPS液晶盒101中基板和液晶分子的初始取向可以为任意角度。
第四种情况，以图2所示的显示面板为例，若液晶盒101为IPS液晶盒101，且显示面板为全反射常黑模式，则液晶分子的取向以及透光轴的设计如下：第一偏光层1021的第一透光轴与IPS液晶盒101靠近第一基板1011的液晶分子的取向方向平行，透反层1031的第二透光轴与IPS液晶盒101靠近第二基板1012的液晶分子的取向平行，第二偏光层1032的吸收轴与透反层1031的第二透光轴平行(第二偏光层1032的第三透光轴与透反层1031的第二透光轴垂直)。
参考图11，在液晶层1013未加电的情况下，光线(外界的环境光线或者位于显示面板的显示侧的第二光源组件发出的光线)入射至第一偏光组件102的第一偏光层1021后，生成偏振方向与第一透光轴平行的第一偏振光(线偏振光)。该第一偏振光经过IPS液晶盒101之后变化为第二偏振光(由于不加电的情况下，液晶盒不起作用，因此第二偏振光与第一偏振光的偏振方向相同)。该第二偏振光的偏振方向与透反层1031的第二透光轴平行，因此该第二偏振光可以透过透反层1031照射至第二偏光层1032。第二偏光层1032的吸收轴与透反层1031的第二透光轴平行，因此从透反层1031透过的第二偏振光可以被第二偏光层1032吸收，无光线出射，光线无法返回进入人眼，实现常黑模式，即呈暗态。
参考图12，在液晶层1013加电的情况下，光线(外界的环境光线或者位于 显示面板的显示侧的第二光源组件发出的光线)入射至第一偏光组件102的第一偏光层1021之后，生成偏振方向与第一透光轴平行的第一偏振光(线偏振光)。第一偏振光经过IPS液晶盒101变化为第二偏振光(椭圆偏光)。该第二偏振光的有效偏振光(椭圆偏光可以分解为互相垂直的两个线偏振光的偏振分量，较大分量的线偏振光定义为有效偏振光，较大分量的线偏振光的偏振方向为有效偏振光的偏振方向)的偏振方向与透反层1031的第二透光轴垂直，因此该第二偏振光的有效偏振光被透反层1031反射回IPS液晶盒101。该第二偏振光的有效偏振光经过IPS液晶盒101后偏振方向依然保持不变，即与第一偏光层1021的第一透光轴平行。该第二偏振光的有效偏振光能够通过第一偏光组件102出射，实现白态，即呈亮态。
在该第四种情况下，实际上仅需保证第一偏光层1021的第一透光轴与透反层1031的第二透光轴平行即可实现上述IPS液晶盒101的常黑模式。IPS液晶盒101中基板和液晶分子的初始取向可以为任意角度。
其中，对于IPS液晶盒101，将第三种情况的常白模式中透反层1031和第二偏光层1032同时旋转90°即可得到对于第四种情况的常黑模式。
第五种情况，以图2所示的显示面板为例，若液晶盒101为VA液晶盒101，且显示面板为全反射常白模式，则液晶分子的取向以及透光轴的设计如下：第一偏光层1021的第一透光轴与透反层1031的第二透光轴垂直，第二偏光层1032的吸收轴与透反层1031的第二透光轴平行(第二偏光层1032的第三透光轴与透反层1031的第二透光轴垂直)。VA液晶盒101按照VA的任意取向模式均可。
参考图13，在液晶层1013未加电的情况下，光线(外界的环境光线或者位于显示面板的显示侧的第二光源组件发出的光线)入射至第一偏光组件102的第一偏光层1021后，生成偏振方向与第一透光轴平行的第一偏振光(线偏振光)。该第一偏振感光经过VA液晶盒101之后变化为第二偏振光(由于不加电的情况下，液晶盒不起作用，因此第二偏振光与第一偏振光的偏振方向相同)。该第二偏振光的偏振方向与透反层1031的第二透光轴垂直，因此该第二偏振光被透反层1031反射回VA液晶盒101。该第二偏振光经过VA液晶盒101后偏振方向依然保持不变，即与第一偏光层1021的第一透光轴平行。该第二偏振光能够通过第一偏光组件102出射，实现常白模式，即呈亮态。
参考图14，在液晶层1013加电的情况下，光线(外界的环境光线或者位于 显示面板的显示侧的第二光源组件发出的光线)入射至第一偏光组件102的第一偏光层1021之后，生成偏振方向与第一透光轴平行的第一偏振光(线偏振光)。第一偏振光经过VA液晶盒101之后变化为第二偏振光(椭圆偏光)。该第二偏振光的有效偏振光(椭圆偏光可以分解为互相垂直的两个线偏振光的偏振分量，较大分量的线偏振光定义为有效偏振光，较大分量的线偏振光的偏振方向为有效偏振光的偏振方向)的偏振方向与透反层1031的第二透光轴平行，因此该第二偏振光的有效偏振光可以透过透反层1031照射至第二偏光层1032。第二偏光层1032的吸收轴与透反层1031第二透光轴平行，因此从透反层1031透过的第二偏振光的有效偏振光可以被第二偏光层1032吸收，无光线出射，光线无法返回进入人眼，实现黑态，即呈暗态。
第六种情况，以图2所示的显示面板为例，若液晶盒101为VA液晶盒101，且显示面板为全反射常黑模式，则液晶分子的取向以及透光轴的设计如下：第一偏光层1021的第一透光轴与透反层1031的第二透光轴平行，第二偏光层1032的吸收轴与透反层1031的第二透光轴平行(第二偏光层1032的第三透光轴与透反层1031的第二透光轴垂直)。VA液晶盒101按照VA的任意取向模式均可。
参考图15，在液晶层1013未加电的情况下，光线(外界的环境光线或者位于显示面板的显示侧的第二光源组件发出的光线)入射至第一偏光组件102的第一偏光层1021后，生成偏振方向与第一透光轴平行的第一偏振光(线偏振光)。该第一偏振光经过VA液晶盒101之后变化为第二偏振光(由于不加电的情况下，液晶盒不起作用，因此第二偏振光与第一偏振光的偏振方向相同)。该第二偏振光的偏振方向与透反层1031的第二透光轴平行，因此该第二偏振光可以透过透反层1031照射至第二偏光层1032。第二偏光层1032的吸收轴与透反层1031的第二透光轴平行，因此从透反层1031透过的第二偏振光可以被第二偏光层1032吸收，无光线出射，光线无法返回进入人眼，实现常黑模式，即呈暗态。
参考图16，在液晶层1013加电的情况下，光线(外界的环境光线或者位于显示面板的显示侧的第二光源组件发出的光线)入射至第一偏光组件102的第一偏光层1021之后，生成偏振方向与第一透光轴平行的第一偏振光(线偏振光)。第一偏振光经过VA液晶盒101之后变化为第二偏振光(椭圆偏光)。该第二偏振光的有效偏振光(椭圆偏光可以分解为互相垂直的两个线偏振光的偏振分量，较大分量的线偏振光定义为有效偏振光，较大分量的线偏振光的偏振方向为有 效偏振光的偏振方向)的偏振方向与透反层1031的第二透光轴垂直，因此该第二偏振光的有效偏振光被透反层1031反射回VA液晶盒101。该第二偏振光的有效偏振光经过IPS液晶盒101后偏振方向依然保持不变，即与第一偏光层1021的第一透光轴平行。该第二偏振光的有效偏振光能够通过第一偏光组件102出射，实现白态，即呈亮态。
需要说明的是，结合上述几种情况可以看出，经过第一偏光层1021之后的线偏振光，若经过加电的IPS液晶盒的液晶层或经过加电的VA液晶盒的液晶层，则线偏振光可以转变为椭圆偏光。该椭圆偏光可以分解为互相垂直的两个线偏振光的偏振分量，较大分量的线偏振光定义为有效偏振光，较大分量的线偏振光的偏振方向即为有效偏振光的偏振方向。另外，如果经过未加电的IPS液晶盒的液晶层或经过未加电的VA液晶盒的液晶层，则线偏振光的偏振方向保持不变。
在本申请实施例中，显示面板10可以实现常白模式，也可以实现常黑模式。由此可以基于显示面板10的具体应用场景选取不同的模式。可选的，手机，手表以及电视机等产品可以用于常黑模式。执法仪，运动码表，价签以及单词卡等产品可以用于常白模式。
在本申请实施例中，若显示面板10的显示侧没有设置第二光源组件，那么单纯通过环境光来满足反射式显示面板的显示可靠性比较低。例如，在环境光不足(较暗)时，难以通过环境光来实现反射显示。由此，显示面板可以包括位于第二偏光组件103远离液晶盒101的一侧的第一光源组件，该第一光源组件可以发出光线，该第一光源组件发出的光线可以用于在环境光不足时实现补光作用。当然，显示面板也可以同时包括第一光源组件和第二光源组件。
由于第二偏光层1032的第三透光轴与透反层1031的第二透光轴垂直，因此第一光源组件(位于第二偏光组件103远离液晶盒101的一侧)发出的光线先通过第二偏光层1032之后会先转变为偏振方向与第三透光轴平行的偏振光，该偏振光是无法通过与第二透光轴的透反层1031透射的。这种情况下，第一光源组件发出的光线无法被利用。由此，为了使得第一光源组件发出的光线能够照射至液晶盒101被利用，需使得第二偏光层1032和透反层1031中的其中一层具有多个开口。该开口可以用于供第一光源组件的光线透过。
第一种方式，参考图17，第二偏光层1032具有多个开口a(图中仅示意了 一个开口)。第二偏光层1032中的多个开口a用于供第一光源组件发出的光线透过，透反层1031用于基于通过多个开口透过的光线生成与第二透光轴平行的偏振光。
以TN液晶盒101的常白反射模式为例，光路说明如下：
参考图18和图19，对于第二偏光层1032的非开口位置，无论液晶层1013是否加电，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线经过第二偏光层1032后，生成偏振方向与第三透光轴平行的偏振光。该第一偏振光照射至透反层1031，由于透反层1031的第二透光轴与第三透光轴垂直，因此该偏振光无法透过透反层1031。
参考图18，对于第二偏光层1032的开口位置，在液晶层1013不加电的情况下，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线通过第二偏光层1032的开口照射至透反层1031。该透反层1031基于通过第二偏光层1032的开口透过的光线生成与第二透光轴平行的偏振光(假设称为第一偏振光，该第一偏振光为线偏振光)，该第一偏振光经过TN液晶盒101之后偏振方向旋转90°，得到第二偏振光(线偏振光)。该第二偏振光的偏振方向与第一偏光层1021的第一透光轴垂直，无光线出射，光线无法进入人眼，呈暗态。
参考图19，对于第二偏光层1032的开口位置，在液晶层1013加电的情况下，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线通过第二偏光层1032的开口照射至透反层1031。该透反层1031基于通过第二偏光层1032的开口透过的光线生成与第二透光轴平行的偏振光(假设称为第一偏振光，该第一偏振光为线偏振光)，该第一偏振光经过TN液晶盒101之后偏振方向保持不变，仍为第一偏振光。该第一偏振光的偏振方向与第一偏光层1021的第一透光轴平行，光线可以出射，呈亮态。
需要说明的是，TN常白反射模式可以是指外界的环境光线发出的光线可以通过非开口位置出射。此种情况下，显示面板处于TN常白反射模式。并且，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线无法通过第二偏光层1032设置的开口a出射(透射为常黑模式)。其中，TN常白反射模式以及透射常黑模式不能同时使用。
另外，若TN液晶盒为TN常黑反射模式(外界的环境光线发出的光线无法 通过非开口位置出射)，则显示面板处于TN常黑反射模式。并且，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线可以通过第二偏光层1032设置的开口a出射(透射为常白模式)。其中，TN常黑反射模式以及透射常白模式不能同时使用。
以IPS液晶盒101的常黑反射模式为例，光路说明如下：
参考图20和图21，对于第二偏光层1032的非开口位置，无论液晶层1013是否加电，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线经过第二偏光层1032后，生成偏振方向与第三透光轴平行的偏振光。该偏振光照射至透反层1031，由于透反层1031的第二透光轴与第三透光轴垂直，因此该偏振光无法透过透反层1031。
参考图20，对于第二偏光层1032的开口位置，在液晶层1013不加电的情况下，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线通过第二偏光层1032的开口照射至半透半返膜层。该透反层1031基于通过第二偏光层1032的开口透过的光线生成与第二透光轴平行的偏振光(假设称为第一偏振光，该第一偏振光为线偏振光)，该第一偏振光经过IPS液晶盒101之后变化为第二偏振光(由于不加电的情况下，液晶盒不起作用，因此第二偏振光与第一偏振光的偏振方向相同)，该第二偏振光的偏振方向与第一偏光层1021的第一透光轴平行，光线可以出射，呈亮态。
参考图21，对于第二偏光层1032的开口位置，在液晶层1013加电的情况下，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线通过第二偏光层1032的开口照射至透反层1031。该透反层1031基于通过第二偏光层1032的开口透过的光线生成与第二透光轴平行的偏振光(假设称为第一偏振光，该第一偏振光为线偏振光)，该第一偏振光经过IPS液晶盒101之后变化为第二偏振光(椭圆偏光)。该第二偏振光的有效偏振光(椭圆偏光可以分解为互相垂直的两个线偏振光的偏振分量，较大分量的线偏振光定义为有效偏振光，较大分量的线偏振光的偏振方向为有效偏振光的偏振方向)的偏振方向与第一偏光层1021的第一透光轴垂直，无光线出射，光线无法进入人眼，呈暗态。
需要说明的是，IPS常黑反射模式可以是指外界的环境光线发出的光线无法通过非开口位置出射。此种情况下，显示面板处于IPS常黑反射模式。并且， 位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线可以通过第二偏光层1032设置的开口a出射(透射为常白模式)。其中，IPS常黑反射模式以及透射白模式不能同时使用。
另外，若IPS液晶盒为IPS常白反射模式(外界的环境光线发出的光线无可以通过非开口位置出射)则显示面板处于IPS常白反射模式。并且，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线无法通过第二偏光层1032设置的开口a出射(透射为常黑模式)。其中，TN常白反射模式以及透射常黑模式不能同时使用。
以VA液晶盒101的常白反射模式为例，光路说明如下：
参考图22和图23，对于第二偏光层1032的非开口位置，无论液晶层1013是否加电，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线经过第二偏光层1032后，生成偏振方向与第三透光轴平行的偏振光。该偏振光照射至透反层1031，由于透反层1031的第二透光轴与第三透光轴垂直，因此该偏振光无法透过透反层1031。
参考图22，对于第二偏光层1032的开口位置，在液晶层1013不加电的情况下，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线通过第二偏光层1032的开口照射至透反层1031。该透反层1031基于通过第二偏光层1032的开口透过的光线生成与第二透光轴平行的偏振光(假设称为第一偏振光，该第一偏振光为线偏振光)，该第一偏振光经过VA液晶盒101之后变化为第二偏振光(由于不加电的情况下，液晶盒不起作用，因此第二偏振光与第一偏振光的偏振方向相同)。该第二偏振光的偏振方向与第一偏光层1021的第一透光轴垂直，无光线出射，光线无法进入人眼，呈暗态。
参考图23，对于第二偏光层1032的开口位置，在液晶层1013加电的情况下，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线通过第二偏光层1032的开口照射至透反层1031。该透反层1031基于通过第二偏光层1032的开口透过的光线生成与第二透光轴平行的偏振光(假设称为第一偏振光，该第一偏振光为线偏振光)，该第一偏振光经过VA液晶盒101之后变化为第二偏振光(椭圆偏光)。该第二偏振光的有效偏振光(椭圆偏光可以分解为互相垂直的两个线偏振光的偏振分量，较大分量的线偏振光定义为有效偏振光，较大分量的线偏振光的偏振方向为有效偏振光的偏振方向)的偏振方向 与第一偏光层1021的第一透光轴平行，光线可以出射，呈亮态。
需要说明的是，VA常白反射模式可以是指外界的环境光线发出的光线可以通过非开口位置出射。此种情况下，显示面板处于VA常白反射模式。并且，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线无法通过第二偏光层1032设置的开口a出射(透射为常黑模式)。其中，VA常白反射模式以及透射常黑模式不能同时使用。在外界的环境光线较充足的情况下(如白天)可以为常白反射模式，在外界的环境光线较暗的情况下(如夜晚)可以为常黑透射模式。
另外，VA常黑反射模式可以是指外界的环境光线发出的光线可以通过非开口位置出射。此种情况下，显示面板处于VA常黑反射模式。并且，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线无法通过第二偏光层1032设置的开口a出射(透射为常黑模式)。其中，VA常黑反射模式以及透射白模式不能同时使用。
第二种方式，参考图24，透反层1031具有多个开口a。第二偏光层1032用于基于第一光源组件发出的光线生成偏振方向与第三透光轴平行的偏振光。透反层1031中的开口a用于透过该偏振光。
以TN液晶盒101的常白反射模式为例，光路说明如下：
参考图25和图26，对于透反层1031的非开口位置，无论液晶层1013是否加电，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线经过第二偏光层1032后，生成偏振方向与第三透光轴平行的偏振光。该第一偏振光照射至透反层1031，由于透反层1031的第二透光轴与第三透光轴垂直，因此该偏振光无法透过透反层1031。
参考图25，对于透反层1031的开口位置，在液晶层1013不加电的情况下，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线照射至第二偏光层1032时，该第二偏光层1032可以生成偏振方向与第三透光轴平行的偏振光(假设称为第一偏振光，该第一偏振光为线偏振光)。该第一偏振光通过透反层1031的开口入射至TN液晶盒101，该第一偏振光经过TN液晶盒101之后偏振方向旋转90°，得到第二偏振光(线偏振光)。该第二偏振光的偏振方向与第一偏光层1021的第一透光轴平行，光线可以出射，呈亮态。
参考图26，对于透反层1031的开口位置，在液晶层1013加电的情况下， 位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线照射至第二偏光层1032时，该第二偏光层1032可以生成偏振方向与第三透光轴平行的偏振光(假设称为第一偏振光，该第一偏振光为线偏振光)。该第一偏振光经过TN液晶盒101之后偏振方向保持不变，仍为第一偏振光。该第一偏振光的偏振方向与第一偏光层1021的第一透光轴垂直，无光线出射，光线无法进入人眼，呈暗态。
需要说明的是，TN常白反射模式可以是指外界的环境光线发出的光线可以通过非开口位置出射。此种情况下，显示面板处于TN常白反射模式。并且，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线可以通过透反层1031设置的开口a出射(透射为常白模式)。其中，TN常白反射模式以及透射常白模式可以同时使用。
另外，若TN液晶盒为TN常黑反射模式(外界的环境光线发出的光线无法通过非开口位置出射)，则显示面板处于TN常黑反射模式。并且，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线无法通过透反层1031设置的开口a出射(透射为常黑模式)。其中，TN常黑反射模式以及透射常黑模式可以同时使用。
以IPS液晶盒101的常黑反射模式为例，光路说明如下：
参考图27和图28，对于透反层1031的非开口位置，无论液晶层1013是否加电，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线经过第二偏光层1032后，生成偏振方向与第三透光轴平行的偏振光。该偏振光照射至透反层1031，由于透反层1031的第二透光轴与第三透光轴垂直，因此该偏振光无法透过透反层1031。
参考图27，对于透反层1031的开口位置，在液晶层1013不加电的情况下，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线照射至第二偏光层1032时，该第二偏光层1032可以生成偏振方向与第三透光轴平行的偏振光(假设称为第一偏振光，该第一偏振光为线偏振光)。该第一偏振光通过透反层1031的开口入射至IPS液晶盒101，该第一偏振光经过IPS液晶盒101之后变化为第二偏振光(由于不加电的情况下，液晶盒不起作用，因此第二偏振光与第一偏振光的偏振方向相同)。该第二偏振光的偏振方向与第一偏光层1021的第一透光轴垂直，无光线出射，光线无法进入人眼，呈暗态。
参考图28，对于透反层1031的开口位置，在液晶层1013加电的情况下，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线照射至第二偏光层1032时，该第二偏光层1032可以生成偏振方向与第三透光轴平行的偏振光(假设称为第一偏振光，该第一偏振光为线偏振光)。该第一偏振光经过IPS液晶盒101之后变化为第二偏振光(椭圆偏光)。该第二偏振光的有效偏振光(椭圆偏光可以分解为互相垂直的两个线偏振光的偏振分量，较大分量的线偏振光定义为有效偏振光，较大分量的线偏振光的偏振方向为有效偏振光的偏振方向)的偏振方向与第一偏光层1021的第一透光轴平行，光线可以出射，呈亮态。
需要说明的是，IPS常黑反射模式可以是指外界的环境光线发出的光线无法通过非开口位置出射。此种情况下，显示面板处于TN常黑反射模式。并且，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线无法通过透反层1031设置的开口a出射(透射为常黑模式)。其中，IPS常黑反射模式以及透射常黑模式可以同时使用。
另外，若TN液晶盒为TN常白反射模式(外界的环境光线发出的光线可以通过非开口位置出射)，则显示面板处于TN常白反射模式。并且，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线可以通过透反层1031设置的开口a出射(透射为常白模式)。其中，IPS常白反射模式以及透射常白模式可以同时使用。
以VA液晶盒101的常白反射模式为例，光路说明如下：
参考图29和图30，对于透反层1031的非开口位置，无论液晶层1013是否加电，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线经过第二偏光层1032后，生成偏振方向与第三透光轴平行的偏振光。该偏振光照射至透反层1031，由于透反层1031的第二透光轴与第三透光轴垂直，因此该偏振光无法透过透反层1031。
参考图29，对于透反层1031的开口位置，在液晶层1013不加电的情况下，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线照射至第二偏光层1032时，该第二偏光层1032可以生成偏振方向与第三透光轴平行的偏振光(假设称为第一偏振光，该第一偏振光为线偏振光)。该第一偏振光通过透反层1031的开口入射至VA液晶盒101，该第一偏振光经过VA液晶盒 101之后变化为第二偏振光(由于不加电的情况下，液晶盒不起作用，因此第二偏振光与第一偏振光的偏振方向相同)。该第二偏振光的偏振方向与第一偏光层1021的第一透光轴平行，光线可以出射，呈亮态。
参考图30，对于透反层1031的开口位置，在液晶层1013加电的情况下，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线照射至第二偏光层1032时，该第二偏光层1032可以生成偏振方向与第三透光轴的偏振光(假设称为第一偏振光，该第一偏振光为线偏振光)。该第一偏振光经过VA液晶盒101之后变化为第二偏振光(椭圆偏光)。该第二偏振光的有效偏振光(椭圆偏光可以分解为互相垂直的两个线偏振光的偏振分量，较大分量的线偏振光定义为有效偏振光，较大分量的线偏振光的偏振方向为有效偏振光的偏振方向)的偏振方向与第一偏光层1021的第一透光轴垂直，无光线出射，光线无法进入人眼，呈暗态。
需要说明的是，VA常白反射模式可以是指外界的环境光线发出的光线可以通过非开口位置出射。此种情况下，显示面板处于TN常白反射模式。并且，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线可以通过透反层1031设置的开口a出射(透射为常白模式)。其中，VA常白反射模式以及透射常白模式可以同时使用。
另外，若VA液晶盒为VA常黑反射模式(外界的环境光线发出的光线无法通过非开口位置出射)，则显示面板处于VA常黑反射模式无法通过透反层1031设置的开口a出射(透射为常黑模式)。其中，VA常黑反射模式以及透射常黑模式可以同时使用。
相对于在第二偏光层1032设计开口的方案而言，在透反层1031设计开口的方案会牺牲一部分透反层1031的反射面积，降低反射显示面板的显示侧的光线的反射效果，可能会对显示效果有一点影响。
需要说明的是，附图5至附图16中的双向箭头均用于表示光线的方向，虚线单箭头用于表示光线的光路。其中两个双向箭头相交表示光线的方向为多种方向，一个双向箭头表示偏振光的偏振方向。附图18至附图23，以及附图25至附图30中的双向箭头用于表示透光轴的透光方向，虚线单箭头用于表示光线。
在本申请实施例中，图31是本申请实施例提供的另一种显示面板的结构示意图。参考图31，显示面板10还包括具有多个像素电路的阵列基板104。参考 图32，该阵列基板104可以具有多个像素区域b，每个像素区域b包括显示区b1以及非显示区b2，像素电路位于非显示区b2。第二偏光层1032或透反层1031中的每个开口a在阵列基板104上的正投影位于一个像素区域b的显示区b1。
可选的，通常情况下，光学膜(例如第二偏光组件103就是一种光学膜)的贴附没有对位标记，精度普遍不高，只需使得开口a不偏出像素区域b的显示区b1即可。例如，像素尺寸为150μm(微米)*150um，开口尺寸为50*50um，满足对位精度＝(150+50)/2＝100um即可。再例如，像素尺寸为200*200um，开口尺寸为40*40um，满足的对位精度＝(200+40)/2＝120um即可。
由于开口a是设置在第二偏光层1032或透反层1031，因此与阵列基板104的像素设计无关，不会受到阵列基板104相关制程的影响，成本较低。并且由于开口a的设计与阵列基板104的结构无关，因此上述实施例仅示意性的说明了TN液晶盒101，IPS液晶盒101以及VA液晶盒101对应的显示面板设计，但实际还可以应用于其他类型的液晶盒。
可选的，阵列基板104可以包括衬底基板和驱动电路层，所述衬底基板包括玻璃基板或石英基板，所述驱动电路层包括上述所述的多个像素电路以及多个像素电极，多个像素电路包括多条数据线，多条扫描线以及多个薄膜晶体管。驱动电路层能够根据不同的显示数据为液晶盒101的液晶分子提供不同的偏振电压。液晶盒101中的液晶分子在不同的偏转电压下能实现不同程度的偏转，从而可以实现不同的透过率。
除此之外，该显示面板10还包括：彩膜基板105，彩膜基板105包括多个不同颜色的子像素对应的色阻块。例如包括红色(red，R)子像素对应的红色色阻块，绿色(green，G)子像素对应的绿色色组块，以及蓝色(blue，B)子像素对应的蓝色色阻块。由于不同颜色的子像素出射的光线的透过率不同，因此，透过对应色阻块的红光，绿光，以及蓝光的比例不同，从而实现彩色显示。
在本申请实施例中，作为第二种可选的实现方式，光吸收层1032的材料包括吸光材料。该吸光材料可以包括黑色油墨。
其中，黑色油墨为吸光度较高的材料。可选的，黑色油墨包括：树脂。该黑色油墨是将树脂与黑色颜料以及溶剂等混合材料混合制成的。需要说明的是，该黑色油墨除了可以设置在透反层1031远离液晶盒101的一侧，还可以设置在背板上。本申请实施例通过设置黑色油墨，不仅能够吸收从透反层1031透射的 光线，而且其制作工艺简单，成本较低。
可选的，参考图33，该第二偏光组件103还包括第二粘接层1033，该第二粘接层1033位于透反层1031靠近液晶盒101的一侧。其中，该第二粘接层1033可以用于将透反层1031和第二基板1012粘接。也即是，在光吸收层1032的材料包括吸光材料的情况下，可以无需设计两层保护层(例如第一种实现方式中的第三保护层1035和第四保护层1036)。
在光吸收层1032的材料包括吸光材料的情况下，无论照射至该光吸收层1032上的光线是何种光线，且无论从什么方向照射的光线都可以被该光吸收层1032吸收。例如，显示面板10的显示侧的光线通过第一偏光组件102，液晶盒101以及透反层1031之后为偏振光，该偏振光照射至光吸收层1032并被光吸收层1032吸收。再例如，位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线照射至该光吸收层1032并被光吸收层1032吸收。
由此，在光吸收层1032的材料包括吸光材料的情况下，若需使得位于第二偏光组件103远离液晶盒101的一侧的第一光源组件发出的光线能够被利用，必然需要在该光吸收层1032设计开口，而不能在透反层1031设计开口。其光路设计说明可以参见上述在第二偏光层1032设计开口的相关描述，本申请实施例在此不再赘述。
在本申请实施例中，上述方案均能够实现反射效果，但是对于反射式显示面板而言，需要保证漫反射的效果才能提高显示面板10的显示效果。相关技术中通常是在反射金属层制作凹凸结构，或在第一偏光组件102中增加散射膜层。但是这两种方案成本都比较高，工艺较复杂。
由此，在本申请实施例中，透反层1031与出光面之间的至少一层粘接层经过雾度(Haze)处理，经过雾度处理之后的粘接层可以实现光线的漫反射。将透反层1031与出光面之间的至少一层粘接层经过雾度处理，可以使得透反层1031反射的光线经过该至少一层粘接层之后再从出光面射出，保证漫反射的效果。其中出光面是指第一偏光组件102远离液晶盒101的一面。
在上述第一种实现方式和第二种实现方式中，透反层1031与显示面板10的出光面之间的粘接层包括第一粘接层1022和第二粘接层1033。由此可以具有下述三种方案：1.第一粘接层1022经过雾度处理，第二粘接层1033无需雾度处理；2.第一粘接层1022无需雾度处理，第二粘接层1033经过雾度处理；3.第一 粘接层1022和第二粘接层1033均经过雾度处理。
可选的，雾度处理的范围可以为10％至90％，其中雾度处理值越大，漫反射的效果越好。但是雾度处理值越大可能会影响显示面板的对比度。由此本申请实施例可综合考虑漫反射效果以及对比度来选取合适的雾度处理值，例如雾度处理值可以为80％。
上述第一种方案(第一粘接层1022经过雾度处理，第二粘接层1033无需雾度处理)，第一偏光组件102中经过雾度处理的第一粘接层1022与液晶盒101的第一基板1011粘接。上述第二种方案(第一粘接层1022无需雾度处理，第二粘接层1033经过雾度处理)，第二偏光组件103中经过雾度处理的第二粘接层1033与液晶盒101的第二基板1012粘接。上述第三种方案(第一粘接层1022和第二粘接层1033均经过雾度处理)，第一偏光组件102中经过雾度处理的第一粘接层1022与液晶盒101的第一基板1011粘接，第二偏光组件103中经过雾度处理的第二粘接层1033与液晶盒101的第二基板1012粘接。另外，经过相关检测发现，上述第二种方案的显示面板的对比度更优。
在本申请实施例中，参考图34，透反层1031可以包括依次交替层叠设置的第一介质层和第二介质层。
其中，第一介质层对偏振方向与第二透光轴平行的偏振光具有第一折射率，对偏振方向与第二透光轴垂直的偏振光具有第二折射率。第一折射率与第二折射率相等。也即是，参考图34和图35，第一介质层为均匀介质层。该第一介质层对偏振方向平行于第一方向X的偏振光的折射率n1与对平行于第二方向Y的偏振光的折射率n2相同。例如，n1＝n2＝1.57。第一方向X与第二透光轴平行，第二方向Y与第二透光轴垂直。
第二介质层对偏振方向与第二透光轴平行的偏振光具有第三折射率，对偏振方向与第二透光轴垂直的偏振光具有第四折射率。第三折射率和第四折射率不相等，且第三折射率与第一折射率相等。也即是，参考图34和图35，第二介质层为双折射介质层，对偏振方向平行于第一方向X的偏转光的折射率n3与对偏振方向平行于第二方向X的偏振光的折射率n4不同。例如，n3＝1.57，n4＝1.8。
其中，第一介质层可以称为非定向层，第二介质层可以称为定向层。
基于上述原理，透反层能够实现某一个偏振方向的光可以透光，另一个偏振方向的光完全反射。如图35所示，透反层1031能够将偏振方向与第一方向X 平行的偏振光进行透射，将偏振方向与第二方向Y平行的偏振光进行反射。
由于偏振光能够通过透反层被全部反射回去，且没有1/2λ波片和1/4λ波片的色散问题，不仅能提高显示亮度，还能提高显示对比度。并且，通过透反层反射偏振光，可以避免制作反射金属层，简化了显示面板的制作工艺。
并且，本申请实施例提供的显示面板通过使用PVA层和APF层，能够避免由于1/2λ波片和1/4λ波片的色散而造成的漏光问题，提高显示对比度。另外，本申请实施例提供的显示面板避免使用成本较高的1/2λ波片和1/4λ波片，从而降低了生产成本。
综上所述，本申请实施例提供了一种显示面板，该显示面板包括液晶盒，第一偏光组件以及第二偏光组件。该第一偏光组件至少包括具有第一透光轴的第一偏光层，用于生成偏振方向与第一透光轴平行的偏振光。第二偏光组件至少包括透反层和光吸收层。透反层具有第二透光轴，用于透射偏振方向与第二透光轴平行的偏振光，且用于反射偏振方向与第二透光轴垂直的偏振光。光吸收层用于吸收透反层透射的偏振光。本申请实施例通过结合第一偏光组件中的第一偏光层，以及第二偏光组件中的透反层和光吸收层来实现反射式显示面板，能够提高显示面板的对比度，且可以批量制备，成本较低。
图36是本申请实施例提供的一种显示装置的结构示意图。参考图36，该显示装置可以包括供电组件20以及如上述实施例所提供的显示面板10。该供电组件20可以用于为显示面板10供电。
另外，该显示装置还包括但不限于：射频单元、网络模块、音频输出单元、输入单元、传感器、显示单元、用户输入单元、接口单元、存储器、处理器、以及电源等部件。本领域技术人员可以理解，上述显示装置的结构并不构成对显示装置的限定，显示装置可以包括上述更多或更少的部件，或者组合某些部件，或者不同的部件布置。在本发明实施例中，显示装置包括但不限于显示器、手机、平板电脑、电视机、可穿戴电子设备、导航显示设备等。
可选的，显示装置可以为：液晶电视、液晶显示器、数码相框、手机、平板电脑等任何具有显示功能的产品或部件，其中，该显示装置还包括柔性电路板、印刷电路板和背板。
