技术领域
本申请涉及显示技术领域，具体涉及一种显示面板以及显示装置。
背景技术
随着电子设备的快速发展，用户对屏占比的要求越来越高，使得电子设备的全面屏显示受到业界越来越多的关注。
传统的电子设备如手机、平板电脑等，需要集成诸如前置摄像头、听筒以及红外感应元件等。一般情况下，可通过在显示屏上开槽(Notch)或开孔，外界光线可通过屏幕上的开槽或开孔进入位于屏幕下方的感光元件。但是，对电子设备的光线透过率的改进会导致显示面板强度变差，影响显示面板的质量。
发明内容
本申请提供一种显示面板以及显示装置，便于感光组件的屏下集成，提高屏占比，并能保证显示面板的整体强度。
一方面，本申请提供一种显示面板，显示面板具有显示区域和围绕显示区域的非显示区域，以及位于显示区域和非显示区域之间的过渡显示区域；显示面板包括显示基板；封装盖板，位于显示基板上，用于密封显示基板；支撑柱，设置在显示基板与封装盖板之间，用于支撑封装盖板；其中，在过渡显示区域内，封装盖板靠近显示基板一侧的表面设置有第一凹槽，和/或显示基板靠近封装盖板一侧的表面设置有第二凹槽。

根据本申请的显示面板以及显示装置，显示面板具有显示区域、围绕显示区域的非显示区 域以及位于显示区域和非显示区域之间的过渡显示区域。非显示区域可以集成驱动电路和柔性电路板(Flexible Printed Circuit，FPC)等元件。显示面板包括显示基板；封装盖板，位于显示基板上，用于密封显示基板；支撑柱，设置在显示基板与封装盖板之间，用于支撑封装盖板，支撑柱能够提高显示面板的显示区域的强度以及耐压能力，防止显示面板出现水波纹、牛顿环等显示不良问题。另外，在过渡显示区域内，封装盖板靠近显示基板一侧的表面设置有第一凹槽，和/或显示基板靠近封装盖板一侧的表面设置有第二凹槽。为了防止显示区域的支撑柱支撑强度低于边缘封装结构如Frit封装结构的支撑强度时产生牛顿环，在过渡显示区域的封装盖板靠近显示基板一侧的表面开设预设深度的第一凹槽，和/或在显示基板靠近封装盖板一侧的表面开设预设深度的第二凹槽，由于普通光源的波列长度为几微米，在封装盖板或显示基板上设置凹槽能够破坏光在浴盆曲线两端的互相干涉的条件，从根本上避免牛顿环现象。
显示面板还具有位于显示区域的透光区域，使得显示面板在透光区域的背面可以集成感光组件，实现例如摄像头等感光组件的屏下集成。在透光区域内，封装盖板靠近显示基板一侧的表面设置有第三凹槽，和/或显示基板靠近封装盖板一侧的表面设置有第四凹槽，可以在保证透光区域的透光率的基础上同时破坏光的互相干涉的条件，从根本上避免牛顿环现象。

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，为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及具体实施例，对本申请进行进一步详细描述。应理解，此处所描述的具体实施例仅被配置为解释本申请，并不被配置为限定本申请。
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。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。
在显示面板研发设计的过程中，一方面，发明人发现如硬屏显示面板包含基板和盖板两大部分，通过屏体(panel)边缘的四周的Frit封装结构实现基板和盖板间的密封。同时会在显示面板的显示区域的基板上各子像素之间设置一定高度和密度的支撑柱(Spacer，SPC)，起到支撑盖板的作用，防止盖板压伤子像素。但是盖板在重力、大气压强、frit封装结构和支撑柱的支撑力等不同因素的联合作用下，盖板变形呈现“浴盆曲线”，距离屏体边缘附近数毫米范围内，由于盖板的急剧变形，光线在此区间的楔形微腔中的传播存在光程差，导致盖板的下表面和基板的上表面这两个表面产生的反射光互相干涉，进而出现牛顿环问题。
另一方面，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区域，将感光组件设置在透光区域背面，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。
集成感光组件的透光区域可以显示静态或动态画面，即此时的透光区域为透光显示区域；透光区域也可以是非显示区域，即此时的透光区域可以是盲孔，盲孔对应的显示面板的膜层结构保留部分透光膜层。通常显示面板上设置有支撑柱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区域的透光率产生影响，为了增加透光区域中的透光率，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区域的支撑强度降低，易使盖板在透光区域产生较大的变形，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，影响显示面板的显示效果。
为了解决上述问题，本申请提供了一种显示面板以及显示装置。下面结合附图对本申请的显示面板以及显示装置进行详细描述。
请一并参阅图1和图6，本申请提供一种显示面板，具有显示区域AA和围绕显示区域AA的非显示区域NA，以及位于显示区域AA和非显示区域NA之间的过渡显示区域TA。非显示区域NA围绕显示区域AA设置，便于在非显示区域NA设置驱动电路和柔性电路板等驱动元件。当然，非显示区域NA也可以设置其他结构，如Frit封装结构等，在此不做限定。显示面板还具有位于显示区域AA的透光区域QA，通过设置能够透光的透光区域QA，将感光组件设置在透光区域QA背面。当透光区域QA是显示区时，在保证感光组件正常工作的情况下，可以实现电子设备的全面屏显示，相较于将感光组件设置在非显示区域NA，本申请提供的显示面板能够有效提高屏占比，便于实现全面显示。本申请中，透光区域QA可以是显示静态或动态画面的显示区，可把用于驱动透光区域QA的像素电路设置于与其邻接的显示区域AA。透光区域QA的透光率可以大于或等于15％。为确保透光区域QA的透光率大于15％，甚至大于40％，甚至具有更高的透光率，本申请中的显示面板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％。在其他实施例中，透光区域QA也可为盲孔结构。
结合图2至图3所示，显示面板包括显示基板100；封装盖板300，位于显示基板100上，用于密封显示基板100；支撑柱200，设置在显示基板100与封装盖板300之间，用于支撑封装盖板300。显示基板100包括衬底110和设置于衬底110上的阵列器件层120。阵列器件层120可包括子像素以及用于驱动子像素发光的像素电路，像素电路的类型可包括1T、2T1C或7T1C等。显示面板还包括设置于衬底110和封装盖板300之间的封装结构400，支撑柱200背离衬底110的一侧与封装结构400背离衬底110的一侧在显示面板的厚度方向上平齐，能够有效防止各支撑柱200与封装结构400的高度不统一而产生牛顿环。
在过渡显示区域TA内，显示基板100与封装盖板300的至少一者设有凹槽，凹槽的设置方式包括如下三种：(1)如图2所示，在过渡显示区域TA内，封装盖板300靠近显示基板100一侧的表面设置有第一凹槽310；(2)，在过渡显示区域TA内，显示基板100靠近封装盖板300一侧的表面设置有第二凹槽320，此种设置方式未进行图示；(3)如图3所示，在过渡显示区域TA内，封装盖板300靠近显示基板100一侧的表面设置有第一凹槽310，显示基板100靠近封装盖板300一侧的表面设置有第二凹槽320。
第一凹槽310的深度大于或等于10微米，小于或等于100微米，或第二凹槽320的深度大于或等于10微米，小于或等于100微米。由于普通光源的波列长度为几微米，在过渡显示区域TA的封装盖板300与支撑柱200的接触表面开设第一凹槽310，并且第一凹槽310的深度大于或等于10微米，即可破坏光的干涉条件，避免出现牛顿环现象。优选的，第一凹槽310 的深度也可为20微米、40微米、50微米或70微米等，只要合理设计第一凹槽310的深度，即可破坏光的干涉条件，避免出现牛顿环现象的同时保证封装盖板300的强度。第二凹槽320设置在过渡显示区域TA的显示基板100与支撑柱200的接触表面，并且第二凹槽320的深度大于或等于10微米，即可破坏光的干涉条件，避免出现牛顿环现象。优选的，第二凹槽320的深度也可为20微米、40微米、50微米或70微米等。如图3所示，显示面板可包括设置于封装盖板300靠近显示基板100一侧的表面的第一凹槽310以及设置于显示基板100靠近封装盖板300一侧的表面的第二凹槽320，第一凹槽310和第二凹槽320在显示基板100上的正投影重合，且第一凹槽310和第二凹槽320的深度之和可大于或等于10微米，小于或等于100微米。上述设置能够减小封装盖板300和显示基板100上的凹槽的深度，进而避免对封装盖板300和显示基板100的强度的影响。
本申请的显示面板，通过在位于过渡显示区域TA的封装盖板300上设置第一凹槽310，和/或在位于过渡显示区域TA的显示基板100上设置第二凹槽320，通过合理设置过渡显示区域TA的宽度、封装盖板300上的第一凹槽310的深度及显示基板100上的第二凹槽320的深度，可以保证显示区域AA向非显示区域NA过渡的区域中，防止产生反射光互相干涉的现象，进而避免出现牛顿环问题，相较于在过渡显示区域TA设置支撑柱200，本申请的显示面板可以从根本上避免牛顿环现象，原因在于：普通光源的波列长度为几微米，如果封装盖板300与支撑柱200的接触表面开设预设深度的凹槽，即破坏了光的互相干涉的条件，避免显示区域的支撑柱200的支撑强度低于边缘封装结构如Frit封装结构的支撑强度时产生牛顿环。
显示面板中还可包括在封装盖板300上设置的第三凹槽330，或在显示基板100上设置的第四凹槽340，或在封装盖板300上设置的第三凹槽330和在显示基板100上设置的第四凹槽340，根据显示面板的实际结构设置即可。
请结合图7和图8所示，在透光区域QA内，第三凹槽330和第四凹槽340的设置方式包括如下三种：(1)结合图7所示，在透光区域QA内，封装盖板300靠近显示基板100一侧的表面设置有第三凹槽330；(2)在透光区域QA内，显示基板100靠近封装盖板300一侧的表面设置有第四凹槽340，此种设置方式未进行图示；(3)结合图8所示，在透光区域QA内，封装盖板300靠近显示基板100一侧的表面设置有第三凹槽330，显示基板100靠近封装盖板300一侧的表面设置有第四凹槽340。
通过上述设置，通过在透光区域QA的封装盖板300上设置第三凹槽330，和/或在透光区域QA的显示基板100上设置第四凹槽340，能够防止产生反射光互相干涉的现象，从根本上 避免出现牛顿环问题。此外，也可以避免在透光区域QA设置支撑柱200，减小支撑柱200对透光区域QA的透光率的影响，有效提高透光区域QA的透光率，通过设置第三凹槽330和/或第四凹槽340，能够破坏光的互相干涉的条件，从根本上避免出现牛顿环现象。
第三凹槽330的深度大于或等于10微米，小于或等于100微米，或第四凹槽340的深度大于或等于10微米，小于或等于100微米。优选的，第三凹槽330或第四凹槽340的深度也可为20微米、40微米、50微米或70微米等，只要合理设计第三凹槽330和第四凹槽340的深度，破坏光的干涉条件，避免出现牛顿环现象的同时保证封装盖板300的强度即可。优选的，第一凹槽310和第三凹槽330的深度可以相同，第二凹槽320和第四凹槽340的深度可以相同，并且可同步制作，简化显示面板的制作工艺。
通过在过渡显示区域TA设置第一凹槽310和/或第二凹槽320，在透光区域QA设置第三凹槽330和/或第四凹槽340，一方面，凹槽能够破坏光的互相干涉的条件，从根本上避免牛顿环现象。原因在于：普通光源的波列长度为几微米，在透光区域QA的封装盖板300与支撑柱200的接触表面开设第三凹槽330以及在过渡显示区域TA的封装盖板300与支撑柱200的接触表面开设第一凹槽310，并且合理设计凹槽的深度，如开设10微米以上的凹槽，即可破坏光的干涉条件，避免出现牛顿环现象。而且实际仿真数据表明，显示面板的封装盖板300的厚度一般在200微米至300微米之间，以封装盖板300的厚度为250微米，透光区域QA的面积一般为3.5平方毫米为例，在封装盖板300上开设深度为10微米的凹槽，封装盖板300的强度下降0.7％，在封装盖板300上开设深度为15微米的凹槽，封装盖板300强度下降5.2％，因此，在封装盖板300上开设凹槽对封装盖板300强度的影响可以忽略不计。
请结合图4和图5所示，本申请所提供的显示面板，显示面板的支撑柱200包括第一环形支撑柱210，第一环形支撑柱210位于靠近过渡显示区域TA的显示区域AA，且围绕过渡显示区域TA设置。第一环形支撑柱210在受到封装盖板300的下压作用时，能够提高支撑柱200的支撑强度，从而减小过渡显示区域TA的封装盖板300的形变量。第一环形支撑柱210的设置方式包括以下两种：
(1)第一环形支撑柱210可以为与过渡显示区域TA的中心同心设置的环形支撑柱，此时，第一环形支撑柱210在显示基板100上的正投影为与过渡显示区域TA同心的环形。其中，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，第一环形支撑柱210在显示基板100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。
(2)第一环形支撑柱210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。第一环形支撑柱210包括第一弧状子支撑柱211和第二弧状子支撑柱212，其中，第一弧状子支撑柱211和第二弧状子支撑柱212位于显示区域AA，且围绕过渡显示区域TA设置。通过上述设置，使得第一环形支撑柱210能够不影响显示区域AA的子像素的开口率，同时设置连续延伸的两个弧状子支撑柱，以提高显示面板的强度。
如图10所示，支撑柱200还包括第二环形支撑柱220，第二环形支撑柱220位于靠近所述透光区域QA的显示区域AA，且围绕透光区域QA设置。本申请中的第二环形支撑柱220在受到封装盖板300的下压作用时，能够有效减小透光区域QA内的封装盖板300的形变量。
第二环形支撑柱220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。具体如图10所示，图10是图6中示出的一种显示面板在Q处的放大示意图。第二环形支撑柱220包括第三弧状子支撑柱221和第四弧状子支撑柱222，其中，第三弧状子支撑柱221和第四弧状子支撑柱222位于与透光区域QA邻接的其他显示区域AA，且围绕透光区域QA设置。通过上述设置，使得第二环形支撑柱220能够不影响显示区域AA的子像素的开口率，同时设置连续延伸的两个弧状子支撑柱，以提高显示面板的强度。
本申请中，支撑柱200设置于显示区域AA，且避让过渡显示区域TA和透光区域QA，即过渡显示区域TA和透光区域QA未设置支撑柱200，通过设置凹槽打破光的干涉条件，从根本上避免牛顿环的产生，并且能够避免支撑柱200对透光区域QA的透光率的影响。
支撑柱200对封装盖板300起到支撑作用，提高显示面板的强度，防止封装盖板300变形或者防止显示面板在受到外界应力作用时发生变形。其中，支撑柱200的组成材料包括但不限于光敏硅氧烷(PSPD0)或光敏聚酰亚胺光刻胶(PSPI)。至少部分支撑柱200内掺杂有刚性条和刚性颗粒的至少一种。刚性条的材料包括硅、钛、钢以及纤维增强复合材料的至少一种；刚性颗粒的材料包括硅、钛、钢以及纤维增强复合材料的至少一种。通过上述设置，可以提高支撑柱200的刚性，防止支撑柱200产生变形或折断。
为便于说明本申请提供的显示面板能够有效改善牛顿环现象，下面结合图9中示出的对比实施例进行说明，图9是对比实施例提供的显示面板的截面示意图。由于图9中支撑柱200的设置不合理，透光区域QA的支撑强度相较于邻接显示区域AA的支撑强度弱，显示面板可为硬性显示面板，显示面板包括显示基板100、封装盖板300以及设置于显示基板100和封装盖板300之间的支撑柱200，各支撑柱200在封装盖300的重力以及大气压强的作用下，易使透光区域QA的支撑柱200的下压量大于邻接显示区域AA的支撑柱200的下压量，在透光区域 QA，封装盖板300向靠近显示基板100方向凹陷，使得封装盖板300与显示基板100构成的微腔发生变化，使得光线入射到封装盖板300表面时，封装盖板300表面反射的光线与显示基板100表面反射的光线存在一定的光程差，反射的光线相互干涉，使得对比实施例示出的显示面板会产生条纹状的牛顿环现象。
参考图11所示，显示面板还包括位于透光区域QA的光调制层500，光调制层500夹设于覆盖透光区域QA的任意相邻透光层之间，光调制层500被配置为至少一部分能够提高预设波长光线在夹设光调制层500的相邻透光层之间的透过率；其中，光调制层500的折射率介于夹设光调制层500的相邻透光层的折射率之间。通过设置光调制层500，能将原本透过率较低的一些波长光线的透过率提升至与透过率较高的波长光线的透过率接近甚至相等，提高光谱透过的均一性，提高透过光线的色彩保真性。并且光调制层500的设置能够起到支撑封装盖板300的作用，防止封装盖板300产生形变。具体参见图11所示，光调制层500可夹设于覆盖透光区域QA的封装盖板300和显示基板100之间，则光调制层500的折射率介于封装盖板300和显示基板100的折射率之间。具体可根据选择的封装盖板300和显示基板100的材料确定。
光调制层500的折射率满足以下式子：
Figure PCTCN2021105942-appb-000001
其中，n A为夹设光调制层500的相邻透光层中的一者的折射率；n B为夹设光调制层500的相邻透光层中的另一者的折射率；n C为光调制层500的折射率；α为有效率，有效率α大于或等于60％。其中，有效率α的值越高，光调制层500的折射率n C越接近相邻透光层的折射率(n A、n B)的几何平均数
Figure PCTCN2021105942-appb-000002
有效率α大于或等于60％，可以保证光调制层500能够将预设波长光线在相邻透光层之间的透过率增强。
参见图12所示，透光区域QA为盲孔结构，即阵列器件层120为具有贯穿通孔的结构。光调制层500设置于衬底110和封装盖板300之间，且光调制层500的折射率介于衬底110和封装盖板300的折射率之间。
参见图13所示，透光区域QA为盲孔结构，即阵列器件层120为具有贯穿通孔的结构。在透光区域QA，衬底110上设置有第五凹槽350，第五凹槽350的深度大于或等于10微米，小于或等于100微米，第五凹槽350在衬底110上的正投影与第三凹槽330在衬底110上的正投影重叠。第三凹槽330与第五凹槽350可同时设置，也可单独设置其中一者，只要能够破坏光 的干涉条件，避免透光区域QA产生牛顿环问题。
本申请还提供一种显示装置，所述显示装置包括如上述任一实施例所述的显示面板和感光组件。显示面板包括相对的第一表面和第二表面，其中第一表面为显示面。感光组件位于显示面板的第二表面所在一侧，感光组件与透光区域QA的位置对应。本申请的显示装置不仅能够实现全面屏显示，而且能够使得显示面板具有较高的透光率，便于感光组件等器件的屏下集成。
感光组件可以是图像采集装置，用于采集外部图像信息。感光组件可以为互补金属氧化物半导体(Complemenry Mel Oxide Semiconductor，CMOS)图像采集装置，感光组件也可以是电荷耦合器件(Charge-coupled Device，CCD)图像采集装置等其它形式的图像采集装置。感光组件可以不限于是图像采集装置，例如在一些实施例中，感光组件也可以是红外传感器、接近传感器、红外镜头、泛光感应元件、环境光传感器以及点阵投影器等光传感器。此外，显示装置在显示面板的第二表面所在一侧还可以集成其它部件，例如是听筒、扬声器等。
根据本申请的显示面板以及显示装置，显示面板具有显示区域、围绕显示区域的非显示区域以及位于显示区域和非显示区域之间的过渡显示区域，非显示区域可以集成驱动电路和柔性电路板(Flexible Printed Circuit，FPC)等元件。显示面板包括显示基板；封装盖板，位于显示基板上，用于密封显示基板；支撑柱，设置在显示基板与封装盖板之间，用于支撑封装盖板；支撑柱能够提高显示面板的显示区域的强度以及耐压能力，防止显示面板出现水波纹、牛顿环等显示不良问题。在过渡显示区域内，封装盖板靠近显示基板一侧的表面设置有第一凹槽，或显示基板靠近封装盖板一侧的表面设置有第二凹槽。为了防止显示区域的支撑柱支撑强度低于边缘封装结构如Frit封装结构的支撑强度时显示面板产生牛顿环现象，在过渡显示区域的封装盖板靠近显示基板一侧的表面开设预设深度的凹槽，和/或在过渡显示区域的显示基板靠近封装盖板一侧的表面开设预设深度的凹槽，由于普通光源的波列长度为几微米，在封装盖板和/或显示基板上设置凹槽能够破坏光在浴盆曲线两端的互相干涉的条件，从根本上避免牛顿环现象。
显示面板还具有位于显示区域的透光区域，使得显示面板在透光显示区的背面可以集成感光组件，实现例如摄像头等感光组件的屏下集成。在透光区域内，封装盖板靠近显示基板一侧的表面设置有第三凹槽，和/或显示基板靠近封装盖板一侧的表面设置有第四凹槽，可以在保证透光区域的透光率的基础上同时破坏光的互相干涉的条件，从根本上避免牛顿环现象。
