Description
本申请涉及显示技术领域，尤其涉及一种显示面板和显示装置。
随着显示技术的发展，有机发光二极管（Organic Light Emitting Diode，OLED）显示屏因具有自发光、广视角、响应时间短、高发光率、色域广、工作电压低、可挠曲等特点，被认为是最具潜力的新型显示装置。其中具有高屏占比的OLED显示屏更受消费者青睐，然而前置摄像头需要显示屏留出一个用于光线通过的透明区域，显示屏在此区域无法显示图像，降低了显示屏的屏占比。为了提升显示屏的屏占比，出现了屏下摄像头技术，屏下摄像头技术需要在显示屏背部进行挖孔来放置摄像头，比如在对应摄像头的位置把显示屏背部的背板开孔，以提高光线的透过率，此时开孔部位的显示屏无基底保护，强度较低，容易刺伤。
因此，现有OLED显示屏在对应屏下摄像区存在的强度低、容易刺伤的问题需要解决。
本申请提供一种显示面板和显示装置，以缓解现有OLED显示屏在对应屏下摄像区存在的强度低、容易刺伤的技术问题。
为解决上述问题，本申请提供的技术方案如下：
本申请实施例提供一种显示面板，其包括显示区以及位于所述显示区内的功能区，所述显示面板还包括：
显示基板；以及
背板，贴附于所述显示基板的背面，包括背板主体以及设置于所述背板主体表面上的结构补强层；
其中，所述背板主体在所述显示基板上的正投影覆盖所述显示区和所述功能区，所述结构补强层在所述显示基板上的正投影至少覆盖所述显示区。
在本申请实施例提供的显示面板中，所述结构补强层设置于所述背板主体面向所述显示基板的表面上。
在本申请实施例提供的显示面板中，所述结构补强层设置于所述背板主体背离所述显示基板的表面上。
在本申请实施例提供的显示面板中，所述结构补强层在所述显示基板上的正投影还覆盖所述功能区。
在本申请实施例提供的显示面板中，所述结构补强层和所述背板主体的相位差均小于或等于10。
在本申请实施例提供的显示面板中，所述结构补强层的厚度大于0微米且小于20微米。

在本申请实施例提供的显示面板中，所述显示面板还包括位于所述显示区一侧的绑定区以及位于所述显示区和所述绑定区之间的弯折区，所述绑定区通过所述弯折区弯折到所述显示基板的背面，其中所述背板在对应所述弯折区的位置断开，使所述背板分为一段背板和二段背板，所述一段背板对应所述显示区和所述功能区，所述二段背板对应所述绑定区。
在本申请实施例提供的显示面板中，所述显示面板还包括设置在所述显示基板背离所述背板一侧的抗反射层，且在靠近所述弯折区的位置所述一段背板的末端以及所述结构补强层的末端均平齐于或超出所述抗反射层的末端。
在本申请实施例提供的显示面板中，所述显示面板还包括设置于所述背板背离所述显示基板一侧的复合功能层，所述复合功能层在对应所述功能区的位置设置有通孔。
本申请实施例还提供一种显示装置，其包括功能元件和前述实施例其中之一的显示面板，所述功能元件设置于背板背离显示基板的一侧，且对应功能区设置。
本申请提供的显示面板和显示装置中，显示面板包括显示区以及位于所述显示区内的功能区，所述显示面板还包括显示基板以及贴附于所述显示基板背面的背板，所述背板包括背板主体以及设置于所述背板主体表面上的结构补强层，所述背板主体采用透光性高的材料，并在所述显示基板上的正投影覆盖所述显示区和所述功能区，所述结构补强层在所述显示基板上的正投影至少覆盖所述显示区，如此所述背板的背板主体呈整面设置，在保证功能区透光性的同时，还能支撑和保护对应功能区的显示基板，解决了现有OLED显示屏在对应屏下摄像区存在的强度低、容易刺伤的问题。同时结构补强层能够提高背板主体的强度和挺性，保证背板的支撑性能。
为了更清楚地说明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单介绍，显而易见地，下面描述中的附图仅仅是发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

以下各实施例的说明是参考附加的图示，用以例示本申请可用以实施的特定实施例。本申请所提到的方向用语，例如[上]、[下]、[前]、[后]、[左]、[右]、[内]、[外]、[侧面]等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本申请，而非用以限制本申请。在图中，结构相似的单元是用以相同标号表示。在附图中，为了清晰理解和便于描述，夸大了一些层和区域的厚度。即附图中示出的每个组件的尺寸和厚度是任意示出的，但是本申请不限于此。
请结合参照图1和图2，图1为本申请实施例提供的显示面板俯视结构示意图，图2为本申请实施例提供的显示面板的一种剖面结构示意图。所述显示面板100包括显示区AA以及位于所述显示区AA内的功能区FA，所述显示区AA是指所述显示面板100用于显示画面的区域，所述功能区FA是指所述显示面板100用于实现摄像等功能的区域，本申请以所述功能区FA实现摄像功能为例说明。所述功能区FA可位于所述显示区AA内的任意位置，把所述功能区FA设置在所述显示区AA内，在所述功能区FA满足摄像等功能的同时，还能用于显示画面，实现所述显示面板100的显示功能，如此可提高所述显示面板100的屏占比。
具体地，所述显示面板100还包括显示基板10和背板20，所述背板20贴附于所述显示基板10的背面，所述显示基板10主要用于实现所述显示面板100的显示功能，所述背板20用于支撑和保护所述显示基板10。其中，所述显示基板10能够显示画面的一面即为所述显示基板10的出光面，与所述显示基板10的出光面相对的一面即为所述显示基板10的背面。
可选地，所述显示面板100包括OLED显示面板、Micro LED显示面板或Mini LED显示面板等，以所述显示面板100为OLED显示面板为例，所述显示基板10可包括衬底基板以及层叠设置在所述衬底基板上的驱动电路层、发光功能层以及封装层等。
所述背板20贴附在所述显示基板10的背面，所述背板20包括背板主体21以及设置于所述背板主体21表面上的结构补强层22，所述背板主体21在所述显示基板10上的正投影覆盖所述显示区AA和所述功能区FA，所述结构补强层22在所述显示基板10上的正投影至少覆盖所述显示区AA。
具体地，所述背板主体21的材料包括透明聚酰亚胺（Colorless
Polyimide，CPI）、超薄玻璃（Ultra Thin Glass，UTG）、环烯烃聚合物（CycloOlefin
Polymer，COP）、三醋酸纤维素（Triacetyl Cellulose，TAC）等具有高透光性的材料中的至少一种。且所述背板主体21材料的相位差小于或等于10，并无各向异性。
可以理解的是，现有习知的背板结构通常采用整面设置的聚对苯二甲酸乙二醇酯（Poly ethylene
terephthalate，PET）基材，而聚对苯二甲酸乙二醇酯的相位差较高，在背板贴合的过程中容易因应变而产生光弹效果，即光穿过背板后会产生双折射现象，从而导致拍照时产生类似水波纹（Ripple）的不良现象，影响屏下摄像头的拍照效果。而为了避免出现水波纹现象，可把对应摄像功能区的背板进行开孔，但如此会导致新的问题，比如对应开孔处的显示基板因没有支撑结构而出现坍塌现象，同时对应开孔处的显示基板因没有保护结构而容易被刺伤。
而本申请采用高透光性以及较小相位差的材料制备所述背板主体21，所述背板主体21呈整面设置，如此不仅能够满足所述功能区FA实现摄像等功能对光线透过率的要求，并能避免出现水波纹现象。同时还能支撑和保护对应所述功能区FA的所述显示基板10，避免该区域的所述显示基板10因没有支撑保护而出现坍塌或刺伤。
但是透明聚酰亚胺、环烯烃聚合物等高透光性以及较小相位差的材料，由于材料本身的强度较差、挺性较低，使得由这些材料制备的所述背板主体21的支撑性能较差。为此，本申请的所述背板20还包括设置在所述背板主体21背离所述显示基板10一侧表面上的结构补强层22。
具体地，所述结构补强层22设置在所述背板主体21的下表面，其中所述背板主体21面向所述显示基板10的一面为所述背板主体21的上表面，与所述背板主体21的上表面相对的即是所述背板主体21的下表面。所述结构补强层22可通过涂布（Coating）、喷涂、物理气相沉积法（Physical Vapor
Deposition，PVD）、化学气相沉积法（Chemical
Vapor Deposition，CVD）等方式形成在所述背板主体21的下表面，对所述背板主体21的结构进行补强，提高所述背板主体21的硬度，进而提高所述背板20的支撑性能。所述背板主体21可通过光学胶（Optically Clear
Adhesive，OCA）等高透光性的胶材与所述显示基板10贴合。
可选地，所述结构补强层22在所述显示基板10上的正投影覆盖所述显示区AA，而在对应所述功能区FA的位置设置第一开孔221，如此因所述结构补强层22不会遮挡所述功能区FA，故该设计对所述结构补强层22的材料的透光性以及相位差无特殊要求，只需所述结构补强层22具有较高的硬度，以能够实现对所述背板主体21的结构补强即可。
同时，为了实现所述显示面板100的柔性，在设置所述结构补强层22提高所述背板20支撑性能的同时，还要兼顾所述背板20的柔性，故可设置较薄的所述结构补强层22，可选地，所述结构补强层22的厚度大于0微米且小于20微米。
另外，所述显示面板100还包括位于所述显示区AA一侧的绑定区BA以及位于所述显示区AA和所述绑定区BA之间的弯折区BD，所述绑定区BA通过所述弯折区BD弯折到所述显示基板10的背面。所述显示基板10在所述弯折区BD设计有各种扇出走线，用于和所述显示基板10在所述显示区AA内的各信号走线连接；所述显示基板10在所述绑定区BA设计有绑定端子，所述绑定端子一端与所述弯折区BD的扇出走线连接，另一端绑定有驱动器或柔性印刷电路板（Flexible Print Circuit，FPC）30，用于给所述显示基板10提供驱动信号。
可选地，所述显示面板100还包括保护层，所述保护层包括UV胶等。所述保护层覆盖在所述显示基板10的弯折区BD并朝所述弯折区BD的两端延伸，以保护所述弯折区BD的扇出走线，避免所述弯折区BD在弯折时发生线路断裂。
所述背板20在对应所述弯折区BD的位置断开，使所述背板20分为一段背板20-1和二段背板20-2，所述一段背板20-1对应所述显示区AA和所述功能区FA，所述二段背板20-2对应所述绑定区BA。当所述绑定区BA弯折到所述显示基板10的背面后，所述一段背板20-1和所述二段背板20-2相对，且所述一段背板20-1和所述二段背板20-2朝向所述弯折区BD的末端平齐。另外因所述背板20包括背板主体21以及设置在所述背板主体21表面的结构补强层22，使得所述背板20具有较强的支撑性能，进而提高了对所述弯折区BD的所述显示基板10的支撑能力，避免所述显示基板10在弯折固定端的位置发生线路断裂（crack）。其中，所述显示基板10的弯折固定端是指与所述弯折区BD弯折起始端连接的水平区域，此区域的显示基板10承受较大的弯折应力，需要对应该区域的背板20提供足够的支撑力，以避免该区域的显示基板10出现坍塌变形而造成该区域的线路断裂。
进一步地，所述显示面板100还包括设置在所述显示基板10背离所述背板20一侧的抗反射层40，所述抗反射层40包括偏光片、彩色滤光片或其他可降低反射率的光学膜层等。所述抗反射层40通过透明光学胶（Optically Clear Adhesive，OCA）等贴附于所述显示基板10的出光面。当外界环境光入射到显示面板100时，所述抗反射层40能够吸收部分外界环境光，避免外界环境光被显示基板10内部的金属线反射，以降低反射率，提高显示面板100的对比度。
可选地，在靠近所述弯折区BD的位置所述一段背板20-1的末端以及所述结构补强层22的末端均平齐于或超出所述抗反射层40的末端，如此可进一步提高所述背板20对弯折区BD的所述显示基板10的支撑性能。
进一步地，所述显示面板100还包括设置于所述背板20背离所述显示基板10一侧的复合功能层60，所述复合功能层60在对应所述功能区FA的位置设置有第二开孔601，以避免影响所述功能区FA的光线透过率，其中所述第二开孔601的尺寸大小和所述第一开孔221的尺寸大小相同，如图2所示，所述第二开孔601和所述第一开孔221之间用虚线隔开，以示区分。
可选地，所述复合功能层60包括第一功能层61和第二功能层62，所述第一功能层61包括泡棉（Foam）等发泡材料，泡棉的机械强度适中，可以弯曲，且弯曲性能弱于显示基板10，能够加强对所述显示基板10的支撑力，避免其局部应力集成。同时泡棉具有较好的隔热作用，能够避免驱动器以及外部走线工作时产生的热量对所述显示区AA造成影响。所述第一功能层61可通过网格胶（embo）等具有粘结作用的胶材贴附于所述一段背板20-1远离所述显示基板10的表面上，网格胶具有易贴合、能排气等有点，使用网格胶进行贴合，可以避免贴合时产生气泡、鼓包等不良现象。
所述第二功能层62贴附于所述第一功能层61远离所述一段背板20-1的一侧，所述第二功能层62包括铜箔、铜箔复合膜等。铜箔复合膜可以是把带胶的聚酰亚胺（Polyimide，PI）、胶材与铜箔进行卷材贴合形成，铜箔复合膜中的PI主要用于增加所述复合功能层60的整体刚性，以增加所述显示基板10背部的抗压能力。铜箔具有优良的导电性能，可以较好的实现电磁屏蔽作用，同时铜箔还具有较好的导热性能，可以实现热量的快速传递，将局部高温区域的热量传递至其他地方，便于热量的均匀分布以及散热。
另外，所述二段背板20-2通过复合胶带70等双面具有粘性的胶带贴附于所述第二功能层62远离所述第一功能层61的一侧，以固定所述显示基板10位于所述绑定区BA的部分。所述复合胶带70可以为双面具有粘性的加固件（Stiffener），通过调节所述复合胶带70的高度可以调节所述弯折区BD的弯折半径。
当然地，所述显示面板100还可以包括设置在所述显示基板10出光侧的盖板80等结构，所述盖板80可通过透明光学胶（Optically Clear
Adhesive，OCA）50等贴附于所述抗反射层40远离所述显示基板10的一侧，用于保护所述显示基板10以及所述抗反射层40等。
可选地，本申请的显示面板100还可包括设置于所述反射层40与所述显示基板10之间的触控功能层（图未示），所述触控功能层直接设置在所述显示基板10上，采用DOT触控方案，以实现触控功能。或者本申请的显示面板100也可以采用外挂式触控方案。
在本实施例中，所述背板20的背板主体21通过采用高透光性以及较小相位差的材料制备，且所述背板主体21呈整面设置，如此不仅能够满足所述功能区FA实现摄像等功能对光线透过率的要求，并能避免出现水波纹现象。同时还能支撑和保护对应所述功能区FA的所述显示基板10，避免该区域的所述显示基板10因没有支撑保护而出现坍塌或刺伤。同时在所述背板主体21的表面设置所述结构补强层22，能够对所述背板主体21的结构进行补强，提高所述背板主体21的硬度，进而提高所述背板20的支撑性能。尤其地提高了所述背板20对所述弯折区BD的所述显示基板10的支撑能力，避免所述显示基板10在弯折固定端的位置发生线路断裂。
在一种实施例中，请参照图3，图3为本申请实施例提供的显示面板的另一种剖面结构示意图。与上述实施例不同的是，所述结构补强层22设置于所述背板主体21面向所述显示基板10的表面上，所述结构补强层22在对应所述功能区FA的位置设置有第一开孔221。所述结构补强层22通过所述透明光学胶（Optically Clear Adhesive，OCA）或压敏胶（Pressure
Sensitive Adhesive，PSA）等贴附于所述显示基板10的背面，优选透明光学胶，因为所述第一开孔221的存在，使得对应所述功能区FA的所述显示基板10和所述背板主体21之间具有间隙，而使用透明光学胶时，可以把透明光学胶填充在所述第一开孔221内，如此不仅不会影响所述功能区FA的透光性，还能提高对该区域所述显示基板10的支撑需求。同时本实施的背板20结构能够实现与上述实施例相同的效果，其他说明请参照上述实施例，在此不再赘述。
在一种实施例中，请参照图4，图4为本申请实施例提供的显示面板的又一种剖面结构示意图。与上述实施例不同的是，所述结构补强层22在所述显示基板10上的正投影还覆盖所述功能区FA，即所述结构补强层22和所述背板主体21均为整面设计。具体地，所述结构补强层22设置于所述背板主体21的下表面，为了使所述结构补强层22不影响所述功能区FA的透光性，可采用透明材料涂布在所述背板主体21的下表面以形成所述结构补强层22。同时为了避免出现水波纹现象，所述结构补强层22的相位差小于或等于10，并无各向异性。而且所述结构补强层22整面设置还能增强所述背板20在对应所述功能区FA位置的支撑性能，进而提高该区域所述背板20对所述显示基板10的支撑性能，避免对应所述功能区FA的所述显示基板10出现坍塌现象。其他说明请参照上述实施例，在此不再赘述。
在一种实施例中，请参照图5，图5为本申请实施例提供的显示面板的再一种剖面结构示意图。与上述实施例不同的是，所述结构补强层22在所述显示基板10上的正投影还覆盖所述功能区FA，且所述结构补强层22设置于所述背板主体21的上表面，如此可实现与上述实施例相同的效果，其他说明请参照上述实施例，在此不再赘述。
在一种实施例中，请参照图6，图6为本申请实施例提供的显示装置的一种剖面结构示意图。所述显示装置1000包括手机、平板、电视等电子设备，具体地，所述显示装置1000包括功能元件200和上述实施例其中之一的显示面板100，所述功能元件200设置于背板20背离显示基板10的一侧，且对应功能区FA设置。
所述功能元件200包括摄像头等，以所述功能元件200为摄像头为例，所述显示面板100的显示区AA用于呈现显示状态；所述功能区FA能够呈现显示状态和透光状态。当所述显示区AA为显示状态且所述功能区FA也为显示状态时，对应所述显示区AA和所述功能区FA的所述显示基板10均执行显示功能，所述摄像头关闭，所述显示装置1000实现全面屏显示。当所述显示区AA为显示状态且所述功能区FA为透光状态时，对应所述显示区AA的所述显示基板10执行显示功能，对应所述功能区FA的所述显示基板10不执行显示功能，外界环境光能够透过对应所述功能区FA的各膜层射入到位于所述显示基板10的背侧的摄像头中，所述摄像头开启，所述显示装置实现拍照功能，并将所述摄像头拍摄的画面传输至所述显示面板100的显示区AA进行显示。
根据上述实施例可知：
本申请提供一种显示面板和显示装置，显示面板包括显示区以及位于所述显示区内的功能区，所述显示面板还包括显示基板以及贴附于所述显示基板背面的背板，所述背板包括背板主体以及设置于所述背板主体表面上的结构补强层，所述背板主体采用透光性高的材料，并在所述显示基板上的正投影覆盖所述显示区和所述功能区，所述结构补强层在所述显示基板上的正投影至少覆盖所述显示区，如此所述背板的背板主体呈整面设置，在保证功能区透光性的同时，还能支撑和保护对应功能区的显示基板，解决了现有OLED显示屏在对应屏下摄像区存在的强度低、容易刺伤的问题。同时结构补强层能够提高背板主体的强度和挺性，保证背板的支撑性能。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
