 本发明的实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。此外，应当理解的是，此处所描述的具体实施方式仅用于说明和解释本申请，并不用于限制本申请。在本申请中，在未作相反说明的情况下，使用的方位词如“上”和“下”通常是指装置实际使用或工作状态下的上和下，具体为附图中的图面方向；而“内”和“外”则是针对装置的轮廓而言的。
请参阅图1，图1是本申请实施例提供的第一种显示面板的截面结构示意图；本申请实施例提供的显示面板，包括基板10、发光层20、保护层30和光调节层40。
所述发光层20设置于所述基板10上，所述发光层20包括多个发光像素201，相邻两个所述发光像素201之间具有间隙202，多个所述发光像素201至少包括红色发光像素、绿色发光像素和蓝色发光像素；所述保护层30设置于所述发光层20远离所述基板10的一侧，所述保护层30包括呈阵列分布的多个挡块301，多个所述挡块301与多个所述间隙202一一对应设置；所述光调节层40设置于相邻两个所述挡块301之间且覆盖所述挡块301。
可以理解的是，本申请实施例通过设置所述保护层30和所述光调节层40，所述光调节层40填充于相邻两个所述挡块301之间，以使所述光调节层40靠近所述基板的一侧形成多个呈阵列分布的微透镜单元402，所述微透镜单元402用于透过所述发光像素201发出的光线，由于所述保护层30的折射率小于所述光调节层40的折射率，即，所述挡块301的折射率小于所述微透镜单元402的折射率，则所述发光像素201发出的光线在所述微透镜单元402和所述挡块301的交界处发生全反射，从而能够将大角度光线向中间区域收敛汇聚，减少了光线的大角度损失以及在膜层之间的全反射损耗，有利于提升显示面板的正向光效和出光效率。
具体地，在一种实施方式中，所述光调节层40的材料可以为压敏胶（聚苯砜对苯二甲酰胺纤维，PSA）或OCA（Optically Clear Adhesive）光学胶，当所述光调节层40的材料为OCA光学胶时，所述光调节层40可采用涂布工艺形成于所述保护层30远离所述基板10的一侧。
请参阅图1，所述显示面板还包括偏光片50，所述偏光片50设置于所述光调节层40远离所述基板10的一侧，所述偏光片50至少包括层叠设置的压敏胶层501、相位差层502、偏光层503和保护膜504。
具体地，所述压敏胶层501用于将所述相位差层502粘合于所述基板10所述保护层30远离所述基板10的一侧，所述压敏胶层501的材料包括PSA（聚苯砜对苯二甲酰胺纤维）材料，PSA材料是一类具有对压力有敏感性的胶粘剂，所述保护膜504用于支撑和保护所述偏光层503。
在本实施方式中，所述发光像素201发出的光线在所述光调节层40和所述挡块301的交界处发生全反射，能够将大角度光线向中间区域收敛汇聚并依次经过所述压敏胶层501、所述相位差层502、所述偏光层503和所述保护膜504之后出射至外界空气中。
进一步地，在另一种实施方式中，请参阅图2，图2是本申请实施例提供的第二种显示面板的截面结构示意图，图2与图1的不同之处在于，所述偏光片50设置于所述保护层30远离所述基板10的一侧，所述压敏胶层501复用为所述光调节层40，在此种情况下，所述发光像素201发出的光线在所述压敏胶层501和所述挡块301的交界处发生全反射，能够将大角度光线向中间区域收敛汇聚并依次经过所述相位差层502、所述偏光层503和所述保护膜504之后出射至外界空气中。
需要说明的是，在本实施方式中，通过将所述压敏胶层501复用为所述光调节层40，相较于图1中的实施方式，无需另外在所述偏光片50和所述保护层30之间新增一层所述光调节层40；而且，当所述光调节层40的材料为PSA材料时，由于PSA材料的流动性较差，很难将PSA材料通过现有涂布工艺制备形成，由于所述偏光片50本身具有所述压敏胶层501，从而有利于减少工艺制程，降低成本；此外，由于省去一层膜层，降低了所述显示面板的整体厚度，有利于实现所述显示面板的轻薄化。
所述压敏胶层501和所述保护层30的材料为有机聚合物，一般地，不同有机聚合物之间的折射率一般差异很小，也就是说，不同膜层之间的折射率一般差异很小，例如，所述压敏胶层501和所述保护层30之间的折射率的差异较小，则，要达到所述压敏胶层501的折射率大于所述保护层30的折射率的目的，通过变更具体有机聚合物材料的方式很难实现，因此，本申请实施例可通过增加所述光调节层40的折射率或减小所述保护层30的折射率的方式来达到上述目的。
具体地，在本申请实施例中，所述压敏胶层501的至少部分区域掺杂有高折射粒子401，和/或，所述挡块301中掺杂有低折射粒子302，现将该几种方式简单说明如下：
请继续参阅图2，在一种实施方式中，所述压敏胶层501的至少部分区域掺杂有高折射粒子401，使得所述压敏胶层501的平均折射率增大，即，使得所述光调节层40的平均折射率增大，进而使得光调节层40的折射率大于所述保护层30的折射率。
在一种实施方式中，请参阅图3，图3是本申请实施例提供的第三种显示面板的截面结构示意图，图3与图2的不同之处在于，所述保护层30中掺杂有低折射粒子302，使得所述保护层30的平均折射率增大，进而使得光调节层40的折射率大于所述保护层30的折射率。
在一种实施方式中，请参阅图4，图4是本申请实施例提供的第四种显示面板的截面结构示意图，图4与图2的不同之处在于，所述压敏胶层501的至少部分区域掺杂有高折射粒子401，且，所述保护层30中掺杂有低折射粒子302，使得所述光调节层40的平均折射率增大，且，所述保护层30的平均折射率增大，从而进一步使得所述光调节层40的折射率大于所述保护层30的折射率。
具体地，所述光调节层40的折射率范围为1.5~2，所述保护层30的折射率范围为1.1~1.4；可选地，所述光调节层40的折射率可以为1.5、1.6、1.7、1.8、1.9、2.0中的其中一种，所述保护层30的折射率可以为1.1、1.15、1.2、1.25、1.3、1.35、1.4的其中一种。
具体地，所述高折射粒子401和所述低折射粒子302均为无色透明折射粒子，以使光线能够透过所述高折射粒子401和所述低折射粒子302，而不会影响透光率。
可选地，所述高折射粒子401包括氧化锆颗粒、氧化钛颗粒、三氧化二铝颗粒和二氧化锆颗粒中的一种或多种，所述高折射粒子401的直径范围为1纳米~300纳米；所述低折射粒子302包括银、铜和二氧化硅中的一种或多种，所述低折射粒子302的直径范围为1纳米~300纳米。
具体地，所述高折射粒子401与所述光调节层40的质量比值范围为1%~40%；所述低折射粒子302与所述保护层30的质量比值范围为1%~40%。
具体地，所述光调节层40的厚度范围为10微米~100微米，这样设置的原因在于，一方面，所述光调节层40的厚度不能过小，防止所述光调节层40的厚度无法有效覆盖所述挡块301，从而导致所述光调节层40远离所述基板10的一侧表面平整性较差；另一方面，所述光调节层40需保证其具有足够的黏附力，以将所述相位差层502粘合于所述基板10所述保护层30远离所述基板10的一侧，避免所述偏光片50发生脱落。
具体地，所述保护层30的厚度范围为1微米~5微米，即，每一所述挡块301的厚度范围为1微米~5微米，以使所述发光像素201发出的大角度光线能够全部射入至每一所述挡块301与所述光调节层40的交界处，从而使得尽可能多的光线向间区域收敛汇聚，有利于进一步减少光线的大角度损失以及在膜层之间的全反射损耗，进而进一步提升了所述显示面板的正向光效和出光效率。
具体地，所述保护层30的材料包括丙烯酸类、硅氧烷类和聚酰亚胺类中的其中一种或多种，可选地，所述保护层30的材料为无色聚酰亚胺、丙烯酸树脂、环氧树脂、有机硅树脂、聚二甲基硅氧烷和六甲基二硅氧烷中的任意一种。
具体地，所述挡块301的截面形状为正三角形和正梯形中的其中一种，例如，图1和图4中的所述挡块301的截面形状为正梯形。
当然地，所述挡块301的截面形状也可以为其他形状，只要能够使得所述发光像素201发出的光线在所述光调节层40和所述挡块301的交界处发生全反射，且全反射光线向所述显示面板的出光面射出即可，本申请实施例对于所述挡块301的截面形状不做特别限定。
进一步地，所述挡块301在所述基板10的正投影位于所述间隙202在所述基板10的正投影内，以避免影响所述发光像素201的正常出光。
具体地，所述挡块301靠近所述基板10的一侧的宽度范围为5微米~50微米，具体应根据所述间隙202的尺寸来定。
进一步地，所述显示面板还包括驱动电路层80和像素定义层90，所述驱动电路层80设置于所述基板10和所述发光层20之间，所述驱动电路层80包括多个像素驱动电路，用于驱动多个所述发光像素201显示发光；所述像素定义层90设置于所述驱动电路层80远离所述基板10的一侧，所述像素定义层90定义出多个像素开口，所述发光层20设置于所述像素开口内，其中，所述间隙202位于相邻两个所述像素开口之间。
进一步地，所述显示面板可以为采用屏上直接触控(Direct On Cell Touch，DOT)结构以形成具有触控功能的电子设备，具体地，所述显示面板还包括封装层60和触控层70，所述封装层60覆盖所述发光层20，所述触控层70设置于所述封装层60远离所述基板10的一侧，所述保护层30设置于所述触控层70远离所述基板10的一侧。
具体地，所述封装层60可以采用薄膜封装结构，所述薄膜封装结构通常包括层叠设置的多层有机薄膜和多层无机薄膜，所述薄膜封装结构的表面为无机封装薄膜，例如氧化锌或其他无机氧化物；所述触控层70包括覆盖所述封装层60的至少一层绝缘介质层和位于所述绝缘介质层中的多个触控单元，所述多个触控单元位于所述间隙202正上方。
需要说明的是，本申请提供的技术方案同样适用于不采用所述DOT结构的显示面板，采用本申请提供的技术方案的任何结构的显示面板均在本申请的保护范围之内。
进一步地，所述显示面板还包括盖板（图中未示出），所述盖板设置于所述偏光片50远离所述基板10的一侧，所述盖板可以为透明玻璃基板10。
