具体实施方式
下面将详细描述本申请的各个方面的特征和示例性实施例。在下面的详细描述中，提出了许多具体细节，以便提供对本申请的全面理解。但是，对于本领域技术人员来说很明显的是，本申请可以在不需要这些具体细节中的一些细节的情况下实施。下面对实施例的描述仅仅是为了通过示 出本申请的示例来提供对本申请的更好的理解。在附图和下面的描述中，至少部分的公知结构和技术没有被示出，以便避免对本申请造成不必要的模糊；并且，为了清晰，可能夸大了部分结构的尺寸。此外，下文中所描述的特征、结构或特性可以以任何合适的方式结合在一个或更多实施例中。
为了更好地理解本申请，下面结合附图对本申请实施方式提供的显示面板及显示装置进行详细描述。
在诸如手机和平板电脑等电子设备上，需要在显示面板的一侧集成诸如前置摄像头、红外光传感器、接近光传感器等感光组件。在一些实施例中，可以在上述电子设备上设置透光显示区，将感光组件设置在透光显示区背面，在保证感光组件正常工作的情况下，实现电子设备的全面屏显示。
通常显示面板上设置有支撑柱(Spacer，SPC)以提高显示面板的整体强度，但是支撑柱的设置会对显示面板的透光显示区的透光率产生影响。为了增加透光显示区中的透光率，会减少支撑柱的布置，例如减小支撑柱的面积或者减小支撑柱的数量，但是在减少支撑柱布置的同时会使得透光显示区的支撑强度降低，易使盖板在第一显示区(第一显示区包括透光显示区)产生较大的变形，使得不同光束在盖板上反射时存在一定的光程差，易导致显示面板产生牛顿环等显示不良现象，因此，在提高显示面板的透光率的同时还要综合考虑支撑柱的设置。
为了解决上述问题，本申请实施例提供了一种显示面板100以及显示装置。下面结合附图对本申请实施例的显示面板100以及显示装置进行详细描述。
请一并参阅图1和图2，图1是本申请实施例提供的显示面板的俯视图，图2是图1中沿B-B方向的剖视图。如图1所示，本申请实施例提供的显示面板100具有第一显示区AA1，第一显示区AA1包括透光显示区，便于在第一显示区AA1集成感光组件，提高显示面板100的屏占比。第一显示区AA1可以为透光显示区，两者的区域完全重叠，当然，第一显示区AA1也可以包括除透光显示区的其他区域。
显示面板100包括衬底10、像素定义层40、第一支撑柱51以及盖板70。像素定义层40位于衬底10上，第一支撑柱51位于像素定义层40的背离衬底10一侧，第一支撑柱51位于第一显示区AA1，盖板70位于第一支撑柱51的背离衬底10的一侧，其中，沿第一显示区AA1的中心至边缘的方向上，第一显示区AA1包括至少两个依次设置的子区AA10，各子区AA10的第一支撑柱51在衬底10上的正投影的总面积占各子区面积的比例不同。
本申请实施例中，第一显示区AA1即透光显示区的透光率可以大于或等于15％。为确保第一显示区AA1的透光率大于15％，进一步大于40％，或甚至确保第一显示区AA1具有更高的透光率，本实施例中显示面板100的至少部分功能膜层的透光率均大于80％，甚至至少部分功能膜层的透光率均大于90％。
本申请实施例的显示面板100，通过合理设置各子区AA10内的第一支撑柱51在衬底10上的正投影的总面积占各子区面积的比例不同，可以在保证第一显示区AA1的透光率的基础上同时保证第一显示区AA1的支撑强度。相较于将第一支撑柱51均匀布置于第一显示区AA1，本申请实施例的显示面板100可以综合第一支撑柱51对透光率以及支撑强度的影响，在提高屏占比的同时提高显示面板100的整体强度，防止第一显示区AA1的支撑强度低于边缘封装结构如Frit(玻璃)封装结构或其他显示区的支撑强度较低时产生牛顿环。
在一些实施例中，显示面板100还可以包括与第一显示区AA1邻接的第二显示区AA2，第二显示区AA2的透光率小于第一显示区AA1的透光率，使得第二显示区AA2能够具有较好的显示效果。在一些实施例中，显示面板100还具有围绕第一显示区AA1以及第二显示区AA2的非显示区NA。相较于将感光组件设置在非显示区NA的显示面板，通过设置能够透光的第一显示区AA1，本申请实施例提供的显示面板100能够有效提高屏占比，便于实现全面显示。
基于此，显示面板100还包括位于像素定义层40和盖板70之间的第二支撑柱52，第二支撑柱52位于第二显示区AA2。第一支撑柱51在衬底 10上的正投影的总面积占第一显示区AA1面积的比例为第一比例，第二显示区AA2的第二支撑柱52在衬底10上的正投影的总面积占第二显示区AA2面积的比例为第二比例，第一比例小于第二比例。通过上述设置，能够减小第一支撑柱51对第一显示区AA1透光率的影响，有效提高第一显示区AA1的透光率，通过设置第一支撑柱51和第二支撑柱52，能够提高显示面板100的强度以及耐压能力，防止显示面板100出现水波纹等显示不良问题。
在第一显示区AA1设置第一支撑柱51，在第二显示区AA2设置第二支撑柱52，一方面，第一支撑柱51和第二支撑柱52可以防止显示面板100的其他膜层结构在利用光罩进行蒸镀时，光罩将显示面板100中已经做好的膜层刮伤。例如，第一支撑柱51和第二支撑柱52能够避免在制备子像素的发光结构时，光罩将已经制备好的发光结构破坏。另一方面，第一支撑柱51和第二支撑柱52能够对盖板70起到支撑作用，提高显示面板100的强度，防止盖板70变形或者防止显示面板100在受到外界应力作用时发生变形。其中，第一支撑柱51的组成材料包括光敏硅氧烷(PSPD0)或光敏聚酰亚胺光刻胶(PSPI)，第二支撑柱52的组成材料包括光敏硅氧烷或光敏聚酰亚胺光刻胶。第一支撑柱51和第二支撑柱52的材料可以相同，第一支撑柱51和第二支撑柱52也可以同步制作，简化显示面板100的制作工艺。
在一些实施例中，沿第一显示区AA1的中心至边缘的方向上，各子区AA10的第一支撑柱51在衬底10上的正投影的总面积占各子区的面积的比例递减或递增。通过上述设置，使得各子区AA10的第一支撑柱51在衬底10上的正投影的总面积占各子区AA10的面积的比例可以灵活配置，在保证第一显示区AA1的透光率的同时提高第一显示区AA1的第一支撑柱51的总体支撑强度。在一可选的实施例中，沿第一显示区AA1的中心至边缘的方向上，包括第一子区、第二子区以及第三子区，第一子区的第一支撑柱在衬底上的正投影的总面积占第一子区的面积的比例为第一比例，第二子区的第一支撑柱在衬底上的正投影的总面积占第二子区的面积的比例为第二比例以及第三子区的第一支撑柱在衬底上的正投影的总面积占第 三子区的面积的比例第三比例，其中，第一比例大于第二比例大于第三比例，或第一比例小于第二比例小于第三比例。
在一些实施例中，沿第一显示区AA1的中心至边缘的方向上，各子区AA10包括与第一显示区AA1的中心同心设置的各环形区域，且沿第一显示区AA1的中心至边缘的方向上，各环形区域宽度相同。通过上述设置，使得各子区AA10的第一支撑柱51在衬底10上的正投影的总面积占各子区AA10的面积的比例呈均匀的配置，在保证第一显示区AA1的透光率的同时提高第一显示区AA1的第一支撑柱51的总体支撑强度。
在具体实施时，沿第一显示区AA1的中心至边缘的方向上，各子区AA10的第一支撑柱51在衬底10上的正投影的总面积占各子区的面积的比例递减。经过受力分析可知，位于第一显示区AA1中心位置处的盖板70的变形量较大，由于第一显示区AA1边缘位置与第二显示区AA2衔接，因此第一显示区AA1边缘位置处的盖板70变形量较小。本申请实施例的上述设置能够有效提高第一显示区AA1的支撑强度，减小盖板70在第一显示区AA1处的变形量，从而有效改善牛顿环等显示不良。
或者，在另一示例中，沿第一显示区AA1的中心至边缘的方向上，各子区AA10的第一支撑柱51在衬底10上的正投影的总面积占各子区的面积的比例递增。通过上述设置，使得第一显示区AA1的中心位置处的透光率较大，便于在第一显示区AA1的中心区域集成感光组件。
在一些实施例中，第一支撑柱51的背离衬底10的一侧、第二支撑柱52的背离衬底10的一侧在显示面板100的厚度方向上平齐。通过上述设置，能够有效防止第一支撑柱51与第二支撑柱52设置不合理而产生牛顿环，同时还能够使得显示面板100具有均匀的耐压能力。
为便于说明本申请实施例提供的显示面板100能够有效改善牛顿环现象，下面结合图3中示出的对比例1进行说明，图3是对比例1提供的显示面板的截面示意图，图3中带箭头的实线以及带箭头的虚线表示光线的传输路径示意。图3中第一支撑柱51和第二支撑柱52的设置不合理，第一显示区AA1的支撑强度相较于第二显示区AA2的支撑强度较弱。当显示面板100为硬性显示面板且显示面板100包括盖板70时，各支撑柱在盖 板70的重力以及大气压强的作用下，易使第一支撑柱51的下压量大于第二支撑柱52的下压量。在第一显示区AA1，盖板70向靠近衬底10方向凹陷，使得盖板70与像素定义层40构成的微腔发生变化，使得光线入射到盖板70表面时，盖板70表面反射的光线与像素定义层40表面反射的光线存在一定的光程差，反射的光线相互干涉，使得对比例1示出的显示面板100会产生条纹状的牛顿环现象。
而本申请实施例中的显示面板100，如图2所示，第一支撑柱51的背离衬底10的一侧、第二支撑柱52的背离衬底10的一侧在显示面板100的厚度方向上平齐，减少盖板70表面反射的光线与像素定义层40表面反射的光线之间的干涉情况，从而有效改善牛顿环。
在一些实施例中，显示面板100还包括封装结构60，第一支撑柱51背离衬底10的一侧、第二支撑柱52背离衬底10的一侧以及封装结构60背离衬底10的一侧在显示面板100的厚度方向上平齐，能够有效防止各支撑柱与封装结构60的高度不统一而产生牛顿环。
为了实现沿第一显示区AA1的中心至边缘的方向上，各子区AA10的第一支撑柱51在衬底10上的正投影的总面积占各子区的面积的比例递减，在一些实施例中，沿第一显示区AA1的中心至边缘的方向上，第一支撑柱51在衬底10上的正投影的面积递减；和/或，沿第一显示区AA1的中心至边缘的方向上，在单位面积内第一支撑柱51的数量递减。
示例性地，沿第一显示区AA1的中心至边缘的方向上，第一支撑柱51在衬底10上的正投影的面积递减可以是相邻子区AA10中的第一支撑柱51在衬底10上的正投影的面积递减，在同一个子区AA10中，第一支撑柱51在衬底10上的正投影的面积相同，此时，可以在像素定义层40上制作两种在衬底10上的正投影的面积不相同的第一支撑柱51，便于工艺制作。或者，也可以设置沿第一显示区AA1的中心至边缘的方向上，每个第一支撑柱51在衬底10上的正投影的面积递减。
图4是图1中示出的显示面板在Q1处的内部结构示例的放大示意图，图5是图1中示出的显示面板在Q1处的内部结构另一示例的放大示意图，图6是图1中示出的显示面板在Q1处的内部结构再一示例的放大 示意图。
如图4所示，在一些实施例中，第一显示区AA1包括第一中央子区AA11以及围绕第一中央子区AA11的第一边缘子区AA12，第一中央子区AA11的第一支撑柱51在衬底10上的正投影的总面积占第一中央子区AA11的面积比例大于第一边缘子区AA12的第一支撑柱51在衬底10上的正投影的总面积占第一边缘子区AA12的面积比例。通过合理设置第一中央子区AA11以及第一边缘子区AA12，使得各子区AA10内的第一支撑柱51能够起到有效的支撑作用，且使得各子区AA10内在各个方位上的支撑强度均一。根据支撑应力分析，通过将第一中央子区AA11中的第一支撑柱51在衬底10上的正投影的总面积占第一中央子区AA11的面积比例设置较大，使得第一中央子区AA11中的第一支撑柱51能够有效支撑盖板70，防止盖板70在第一显示区AA1处产生较大的变形量，从而使得第一显示区AA1和第二显示区AA2的支撑强度趋近。
如图5所示，在一些实施例中，为了有效提高第一显示区AA1的耐压强度，第一显示区AA1包括第一中央子区AA11以及围绕第一中央子区AA11的第一边缘子区AA12。第一中央子区AA11的第一支撑柱51在衬底10上的正投影的总面积占第一中央子区AA11的面积比例为0％～4.8％，第一边缘子区AA12的第一支撑柱51在衬底10上的正投影的总面积占第一边缘子区AA12的面积比例为5％～10％。
在具体实施时，第一中央子区AA11设置有多个第一支撑柱51，多个第一支撑柱51可以均匀散布于第一中央子区AA11，第一中央子区AA11的第一支撑柱51在衬底10上的正投影的总面积占第一中央子区AA11的面积比例可以根据用户的需求进行设定。例如，该比例可以为0.1％、0.3％、1.0％、1.5％、2.4％、4.0％的其中一种，或者，该比例可以为第二显示区AA2的第二支撑柱52在衬底10上的正投影的总面积占第二显示区AA2的面积比例的1/2倍、1/4倍或者1/8倍，第一边缘子区AA12的第一支撑柱51在衬底10上的正投影的总面积占第一边缘子区AA12的面积比例也可以根据用户的需求进行设定，例如，该比例可以为4.9％、5％、6.5％、10％的其中一种，或者该比例也可以但不限于为第二显示区AA2的 第二支撑柱52在衬底10上的正投影的总面积占第二显示区AA2的面积比例的1/2倍、1/4倍或者1/8倍。
为了验证上述的第一支撑柱51的设置方式能够提高显示面板100的支撑强度的同时，减少牛顿环情况，请参阅图7和图8。图7示出了本申请实施例提供的第一支撑柱占第一显示区的第一比例与第一支撑柱的下压量之间的关系图，图8示出了在不同的第一支撑柱占第一显示区的第一比例下的显示效果示意图。图7和图8中，第二显示区AA2的第二支撑柱52在衬底10上的正投影的总面积占第二显示区AA2的面积的第二比例为11％。从仿真结果可以得出，随着第一比例的增加，第一支撑柱51的下压量逐渐减小，此时，从图8中可以得出当第一比例分别为3.20％、3.45％、3.60％以及4.07％时，牛顿环的现象均能有效减弱，当第一比例为4.07％，此时几乎没有牛顿环现象。因此，本申请实施例提供的显示面板100不仅能够提高整体强度，还具有较好的显示效果。
进一步地，为了验证仿真结果的合理性以及进一步验证第一支撑柱51的设置方式能够提高显示面板100的支撑强度的同时，减少牛顿环情况，下面通过表1中所示的实验数据进行说明。
如表1所示，通过合理设置第一支撑柱51在第一显示区AA1的布置比例以及第二支撑柱52在第二显示区AA2的比例，能够有效减小第一支撑柱51的最大下压量，使得盖板70在第一显示区AA1以及第二显示区AA2的下压量趋近，进而第一支撑柱51的背离衬底10的表面与第二支撑柱52的背离衬底10的表面平齐，以有效改善牛顿环的情况发生，提高显示面板100的显示效果。

2 1 11 18.00

4 0.2 15 132.5
如图6所示，为了提高第一支撑柱51的支撑强度，使得第一显示区 AA1的强度与第二显示区AA2的强度均一，第一支撑柱51可以为与第一显示区AA1的中心同心设置的环状支撑柱，此时第一支撑柱51在衬底10上的正投影为围绕第一显示区AA1中心的环形。本文中的环形是指广义上的具有内边缘和外边缘的封闭结构，可以为圆形环、方形环或多边形环的任意一种，第一支撑柱51在第一衬底11上的正投影的内边缘和外边缘可以同心设置以限定出环形。
为便于说明环形支撑柱具有较高的支撑强度，下面引入对比例2进行说明。如图9和图10所示，图9是本申请实施例中提供的第一支撑柱的示例的结构示意图，图10是对比例2提供的第一支撑柱的结构示意图。在对比例2中，第一支撑柱51为单独的柱状支撑柱，多个第一支撑柱51沿第一中央子区AA11的外周侧间隔设置，而本申请实施例中的第一支撑柱51为沿第一中央子区AA11的外周延伸的封闭环状结构。对比例2与本申请实施例的对比结果如下表2所示。从表2可以得出，本申请实施例的环状支撑柱在受到盖板70的下压作用时，能够有效减小第一支撑柱51的下压量，且通过设置本申请实施例的环状支撑柱，盖板70在第一显示区AA1的变形量也显著减小。

为了设置合理的第一支撑柱51，防止第一支撑柱51遮挡第一显示区AA1的子像素显示，在一些实施例中，环状支撑柱包括至少两个弧状子支撑柱，至少两个弧状子支撑柱彼此间隔设置。通过上述设置，使得环状支撑柱能够不影响子像素的开口率，同时设置连续延伸的弧状子支撑柱，以提高显示面板100的支撑强度。
在一些实施例中，显示面板100的对应于第一中央子区AA11的背面可以集成感光组件，为了减少环状支撑柱对第一中央子区AA11的透光率的影响，环状支撑柱位于第一边缘子区AA12，此时可以保证第一显示区AA1的支撑强度。可选地，第一支撑柱51还包括柱状支撑柱，柱状支撑 柱位于第一中央子区AA11，在提高第一中央子区AA11强度的前提下提高第一中央子区AA11的透光率。

可选地，第一显示区AA1包括第一中央子区AA11以及围绕第一中央子区AA11的第一边缘子区AA12，第二边缘子区的第二支撑柱52在衬底 上的正投影的总面积占第二边缘子区的面积比例大于第一边缘子区AA12的第一支撑柱51在衬底上的正投影的总面积占第一边缘子区AA12的面积比例，保证第一显示区的透光率。

进一步的，第一支撑柱51、第二支撑柱52均设置在像素定义层40的非开口区，以对显示面板100进行支撑，同时防止对子像素中的发光结构产生破坏。
在显示面板100制作过程中，通常使用掩膜板制作各子像素的膜层结构，支撑柱还能够用于支撑掩膜板，防止掩膜板对已经成型的膜层结构造成损伤。请进一步参阅图4，在一些实施例中，显示面板100包括第一像素31，第一像素31位于第一显示区AA1。第一像素31包括多个第一色第一子像素310a、多个第二色第一子像素310b和多个第三色第一子像素310c，通过合理设置第一支撑柱51，能够使得第一支撑柱51均能达到对掩膜板较好的支撑效果，防止掩膜板对已经成膜的结构造成损伤。

在一些实施例中，为了提高第一显示区AA1的透光率，第一电极311c为透光电极，可选的，第一电极311c包括氧化铟锡(Indium Tin Oxide，ITO)层或氧化铟锌层。
在一些实施例中，第一电极311c为反射电极且第一电极311c在衬底10上的正投影面积小于第三电极321c在衬底10上的正投影的面积，第一电极311c可以包括第一透光导电层、位于第一透光导电层上的反射层以及位于反射层上的第二透光导电层。其中第一透光导电层、第二透光导电层可以是ITO、氧化铟锌等，反射层可以是金属层，例如反射层是银材质制成。
在一些实施例中，第二电极313c的组成材料包括镁、银或镁银合金。第四电极323c可以配置为与第二电极313c采用相同的材质。在一些实施例中，第二电极313c、第四电极323c可以互连为公共电极。
在一些实施例中，每个第一发光结构312c在衬底10上的正投影由一个第一图形单元组成或由两个以上第一图形单元拼接组成，第一图形单元包括圆形、椭圆形、哑铃形、葫芦形、矩形中的至少一个。

进一步地，显示面板100还可以包括第二显示区AA2以及位于第二显示区AA2的第二支撑柱52，通过设置第一显示区AA1的第一支撑柱51在衬底10上的正投影的总面积占第一显示区AA1面积的比例小于第二显示区AA2的第二支撑柱52在衬底10上的正投影的总面积占第二显示区AA2面积的比例，能够减小第一显示区AA1中的第一支撑柱51对透光率的影响，有效提高第一显示区AA1的透光率。进一步的，沿第一显示区AA1的中心至边缘的方向上，第一显示区AA1包括至少两个子区，通过合理设置各子区内的第一支撑柱51在衬底10上的正投影的总面积占各子区面积的比例不同，可以在保证第一显示区AA1的透光率的基础上同时保证第一显示区AA1的支撑强度与第二显示区AA2的支撑强度趋近。相较于将第一支撑柱51均匀布置于第一显示区AA1，本申请实施例的显示面板100可以在部分子区AA10内设置密度较大的第一支撑柱51以提高该部分子区AA10内的支撑强度，在部分子区AA10内设置密度较小的第一支撑柱51以增加该部分子区AA10内的透光率，以便于在第一显示区AA1的背面集成感光组件以及保证显示面板100的整体强度，从而提高显示面板100的质量。
