Description

显示面板及显示装置 技术领域
本申请涉及显示技术领域，尤其涉及一种显示面板及显示装置。
 背景技术
随着液晶显示技术的发展，特别是全面屏技术的发展，目前多数厂商在显示装置的背光模组中开孔，以供屏下摄像头对应放置，并藉此接收来自外界环境的入射光。
但是，如图1所示，显示面板中的面板主体500中具有大量的金属走线501，背光模组600中的背光源601照射到金属走线501上会通过背光模组600的开孔602反射至屏下摄像头700处，影响屏下摄像头700的拍摄效果。现有技术在面板主体500与背光模组600之间贴合遮光胶带800来避免反射，但是面板主体500中与遮光胶带800贴合的衬底502具有一定的厚度，若遮光胶带800较窄，则背光源601仍会通过衬底502照射到金属走线501上造成反射，影响屏下摄像头700的拍摄效果。

本发明实施例提供的显示面板包括背光模组1和面板主体2，且面板主体2位于背光模组1上。
背光模组1包括背光单元11和光源组件12。背光单元11中设有透光部13，透光部13贯穿背光单元11。透光部13可以为背光孔，即背光孔贯穿背光单元11，背光孔中可以填充透光材料。其中，背光孔13可以为圆形孔，透光材料可以为有机玻璃（PMMA）。面板主体2包括透光区200，透光部13与透光区200的位置相对应，即透光部13在面板主体2上的正投影与透光区200完全重合。通过设置透光区200和透光部13，可以增大显示面板的透光率，保证更多的外部光进入显示面板的底部（即背光单元11背离面板主体2的一侧），从而提高显示面板底部摄像组件的拍摄效果。
具体地，如图3所示，背光单元11可以包括依次设置的反射片112、导光板113、扩散片114、下增光片115和上增光片116。反射片112可以设于背板（图中未示出）上，导光板113设于反射片112上，扩散片114设于导光板113上，下增光片115设于扩散片114上，上增光片116设于下增光片115上，面板主体2可以设于上增光片116上。其中，扩散片114用于对光线扩散以提供一个均匀的面光源，下增光片115和上增光片116用于增强光源的亮度。透光部13依次贯穿所述反射片112、所述导光板113、所述扩散片114、所述下增光片115和所述上增光片116。
光源组件12用于通过所述背光单元11向所述面板主体2提供光源。具体地，所述光源组件12可以包括第一光源121。其中，第一光源121位于所述背光单元11周侧，且第一光源121可以与导光板113相对设置，使第一光源121通过导光板113向面板主体2提供均匀的光源。但由于透光部13贯穿导光板113，导致第一光源121无法向与透光部13相对应的透光区200提供光源，进而导致与透光部13相对应的透光区200无法正常显示。为了保证显示面板的正常显示，光源组件12还可以包括第二光源122，第二光源122可以位于所述背光单元11背离所述面板主体2的一侧，使第二光源122可以通过背光单元11中的透光部13向面板主体2的透光区200提供光源。
具体地，第二光源122可以与透光部13的位置相对应，即第二光源122在背光单元11上的正投影位于透光部13内，第二光源122可以为透明光源，以在显示面板底部的摄像组件进行拍摄时，保证外部光通过第二光源122进入显示面板的底部，在显示面板正常显示时，第二光源122通过透光部13向面板主体2的透光区200提供光源。第二光源122也可以位于透光部13的外侧，即第二光源122在背光单元11上的正投影位于透光部13外，通过在第二光源122与背光单元11之间设置导光环（图中未示出），可以使得第二光源122发出的光束通过导光环进入透光部13，进而通过透光部13进入面板主体2的透光区200，同时第二光源122的设置也不会影响显示面板底部接收外部光。
如图2所示，面板主体2包括衬底21、遮光层22和金属走线23。衬底21靠近背光单元11一侧，遮光层22位于衬底21背离背光单元11的一侧，金属走线23位于遮光层22背离衬底21的一侧，即衬底21位于背光单元11与遮光层22之间，遮光层22位于衬底21与金属走线23之间，且所述遮光层22遮挡所述金属走线23。其中，衬底21可以为玻璃衬底，金属走线23可以为数据线、信号线等，金属走线23的材料可以为钼Mo、钛Ti、铝Al等。
由于金属走线23的反射率为50%左右，导致照射至金属走线23上的光束容易通过透光部13反射至显示面板的底部，影响显示面板底部摄像组件的拍摄效果，因此本实施例在面板主体2的衬底21和金属走线23之间设置遮光层22，且在背光模组1指向面板主体2的方向上，遮光层22覆盖金属走线23，可以有效避免进入至面板主体2的光束通过金属走线23反射至显示面板的底部，提高显示面板底部摄像组件的拍摄效果，且遮光层22位于衬底21与金属走线23之间，即遮光层22靠近金属走线23，使得遮光层22覆盖的区域可以足够小，即可避免光束通过金属走线23反射至显示面板的底部，从而保证显示面板的显示效果不受遮光层22的影响。
面板主体2包括相对设置的彩膜基板2a和阵列基板2b，衬底21、遮光层22和金属走线23为彩膜基板2a和阵列基板2b中的膜层。
在一个实施方式中，如图2所示，彩膜基板2a位于背光单元11上，阵列基板2b位于彩膜基板2a上，即彩膜基板2a位于背光单元11与阵列基板2b之间。衬底21和遮光层22位于彩膜基板2a中，金属走线23位于阵列基板2b中，即彩膜基板2a包括衬底21和遮光层22，且衬底21靠近背光单元11一侧，遮光层22位于衬底21背离背光单元11的一侧，阵列基板2b包括金属走线23。阵列基板2b还可以包括衬底27，衬底27位于金属走线23背离彩膜基板2a的一侧，衬底27可以为玻璃衬底。
彩膜基板2a还包括多个间隔设置的色阻24，遮光层22包括多个遮光块211，每一所述色阻24位于对应的两所述遮光块211之间。其中，遮光块211可以为黑矩阵。本实施例将色阻24周围的遮光块211作为遮光层，可以避免在彩膜基板2a中额外增加遮光层，使得遮光层22既可以分割相邻色阻24以防止漏光或混色，又可以避免光束通过金属走线23反射至显示面板的底部。
根据通过金属走线23反射至透光部13的光束的路线，可以调整遮光块211的分布密度，即遮光块211在面板主体2的不同区域的分布密度可以不同。
具体地，面板主体2还可以包括位于透光区200外的显示区300，即除了透光区200之外的区域都可以为显示区300。显示区300可以包括第一子显示区301和第二子显示区302，第一子显示区301靠近透光区200设置，且第一子显示区301围绕透光区200设置。第二子显示区302位于第一子显示区301外，即除了第一子显示区301之外的其他显示区都可以为第二子显示区302。其中，如图4所示，所述第一子显示区301在朝向所述透光区200的中心O方向A上的长度D1小于所述第二子显示区302在朝向所述透光区200的中心O方向A上的长度D2。
其中，通过第一子显示区301进入面板主体2的光束能够由金属走线23反射至显示面板的底部，因此可以在不影响显示面板的显示效果的基础上，增大第一子显示区301中遮光块221的密度，使第一子显示区301中遮光块211的密度最大，即第一子显示区301中遮光块211的密度大于透光区200中遮光块211的密度，且第一子显示区301中遮光块211的密度大于第二子显示区302中遮光块211的密度，从而避免通过第一子显示区301进入面板主体2的光束照射至金属走线23上，从而避免光束通过金属走线23反射至显示面板的底部。
透光区200中遮光块211的密度可以等于第二子显示区302中遮光块211的密度，或者透光区200中遮光块211的密度可以小于第二子显示区302中遮光块211的密度，或者透光区200中部分区域的遮光块211的密度等于第二子显示区302中遮光块211的密度，透光区201中另一部分区域的遮光块211的密度小于第二子显示区302中遮光块211的密度。
为了进一步增大透光区200的透光率，提高显示面板底部的拍摄效果，减小透光区200中遮光块211的密度，使透光区200中遮光块211的密度最小，即透光区200中遮光块211的密度小于第二子显示区302中遮光块的密度。
具体地，如图4所示，在由显示区300朝向透光区200的中心O的方向A上，透光区200中遮光块211的密度可以逐渐减小。其中透光区200中靠近显示区300的遮光块211的密度可以与第二子显示区302中遮光块211的密度相同，而位于透光区201中心O处的遮光块211的密度最小。或者，在由显示区300朝向透光区201的中心O方向A上，第一子显示区301和透光区200中的遮光块211的密度逐渐减小，即位于第一子显示区301靠近第二子显示区302的遮光块211的密度最大，位于透光区200的中心O处的遮光块211的密度最小。
遮光块211的密度大小可以通过多种方式实现。例如，在遮光块211的宽度（即遮光块211在方向B上的长度）不变时，相邻遮光块211的间距（即色阻24在方向B上的长度）变小，遮光块211的密度变大；相邻遮光块211的间距变大，遮光块211的密度变小。或者，在相邻遮光块211的间距不变时，遮光块211的宽度变大，遮光块211的密度变大；遮光块211的宽度变小，遮光块211的密度变小。或者，在相邻遮光块211的间距和遮光块211的宽度同时变化时，相邻遮光块211的间距变小，且遮光块211的宽度变大，遮光块211的密度变大；相邻遮光块211的间距变大，且遮光块211的宽度变小，遮光块211的密度变小。
如图4所示，第一子显示区301中遮光块211的宽度最大，在由显示区300朝向透光区201的中心O方向上，透光区200中遮光块211的宽度逐渐减小，使得透光区200中遮光块211的密度逐渐减小。具体地，位于第一子显示区301中的遮光块211的宽度W2大于位于透光区200中心O处的遮光块211的宽度W4，而位于两者之间（如位于透光区201边缘处）的遮光块211的宽度W3小于W2，且大于W4，即W2＞W3＞W4。第二子显示区302中遮光块211的宽度W1大于或等于W4，且小于W2，即W2＞W1≥W4。
为了保证面板主体2的显示效果不受影响，第一子显示区301的宽度（即第一子显示区301在方向A上的长度）需要尽可能小，第一子显示区301的最小宽度与所述衬底21的厚度、所述背光模组1与所述衬底21的间距以及所述光源组件12的出光角度范围相关。需要说明的是，由于背光模组1与衬底21之间还设有其他膜层，因此背光模组1与衬底21之间具有间距。
具体地，第一子显示区301的最小宽度与所述衬底21的厚度、所述背光模组1与所述面板主体2的间距以及所述光源组件12的出光角度范围成正比，即衬底21的厚度越大，第一子显示区301的最小宽度越大；背光模组1与衬底21的间距越大，第一子显示区301的最小宽度越大；光源组件12的出光角度范围越大，第一子显示区301的最小宽度越大。需要说明的是，光源组件12的出光角度范围主要是指光源组件12中第一光源121的出光角度范围，即第一光源121的出光角度范围越大，第一子显示区301的最小宽度越大。
为了进一步增大透光区200的透光率，提高显示面板底部摄像组件的拍摄效果，可以在透光区200中增加白色色阻W，即透光区201中的色阻包括红色阻R、绿色色阻G、蓝色色阻B和白色色阻W，如图4所示。而第一子显示区301和第二子显示区302中的色阻可以仅包括红色色阻R、绿色色阻G和蓝色色阻B。需要说明的是，所述透光区200靠近所述显示区300的白色色阻W可以至少部分被遮光块211覆盖，以降低像素开口率，同时保证透光区201靠近显示区300的遮光块211的密度。
在另一个实施方式中，如图5所示，阵列基板2b位于背光单元11上，彩膜基板2a位于阵列基板2b上，即阵列基板2b位于背光单元11与彩膜基板2a之间。衬底21、遮光层22和金属走线23均位于彩膜基板2a中，即阵列基板2b包括衬底21、遮光层22和金属走线23，且衬底21靠近背光单元11一侧，遮光层22位于衬底21背离背光单元11的一侧，金属走线23位于遮光层22背离衬底21的一侧。彩膜基板2a可以包括多个色阻（图中未示出）以及多个遮光块（图中未示出），每一色阻位于其对应的两个遮光块之间。
遮光层22覆盖在金属走线23靠近衬底21的一侧。为了保证显示面板的显示效果不受影响，遮光层22的覆盖区域需要尽可能小。所述遮光层22在所述衬底21上的正投影与所述金属走线23在所述衬底21上的正投影完全重合，以在保证显示面板2的显示效果不受遮光层22的影响的同时，避免光束通过金属走线23反射至显示面板的底部，从而提高显示面板底部摄像组件的拍摄效果。
其中，所述遮光层22的材料为黑金属。例如，金属走线23为钼Mo，则遮光层22可以为氧化钼MoO x。利用氧化钼MoO x的低反射性能，可以有效避免光束照射至金属走线23进而反射至显示面板的底部。
如图3所示，背光模组1还可以包括光反射层15，光反射层15位于透光部13的周侧，即光反射层15覆盖在透光部13的侧壁。其中，光反射层15可以为具有高反射性能的金属膜，例如光反射层15的材料可以为铝。
由于光源组件12中的第一光源121位于背光单元11的周侧，而透光部13贯穿背光单元11，即第一光源121位于透光部13的周侧，使得第一光源121发出的光束可以通过透光部13的侧面进入显示面板的底部，影响显示面板底部的拍摄效果。因此，本实施例在透光部13的侧壁覆盖光反射层15，可以将第一光源121照射至透光部13侧面的光束反射回去，有效避免第一光源121发出的光束通过透光部13的侧面进入显示面板的底部，从而提高显示面板底部的拍摄效果。
另外，由于光反射层15涂覆在透光部13的侧壁，光反射层15的厚度可以很薄，即可达到高反射的效果。因此，背光单元11中无需再设置光线阻隔膜（现有技术中的背光单元包括位于背光孔周侧的光线阻隔膜，该光线阻隔膜的厚度较厚且不向面板主体导光，会影响光线阻隔膜对应的面板主体区域的显示），避免光线阻隔膜影响其对应的面板主体区域的显示，而光反射层15很薄，光反射层15所影响的面板主体区域可以忽略不计，从而提高面板主体2的显示效果。
进一步地，如图2和图5所示，面板主体2还可以包括下偏光片25和上偏光片26，下偏光片25位于背光单元11与衬底21之间，上偏光片26位于金属走线23背离衬底21的一侧。在面板主体2的彩膜基板2a靠近背光单元11一侧时，即彩膜基板2a位于背光单元11与阵列基板2b之间时，下偏光片25位于背光单元11与彩膜基板2a之间，上偏光片26位于阵列基板2b背离彩膜基板2a的一侧。在面板主体2的阵列基板2b靠近背光单元11一侧时，即阵列基板2b位于背光单元11与彩膜基板2a之间时，下偏光片25位于背光单元11与阵列基板2b之间，上偏光片26位于彩膜基板2a背离阵列基板2b的一侧。
下偏光片25和上偏光片26中还可以分别设置通孔（图中未示出），且通孔与背光孔13的位置相对应，通孔的设置可以进一步提高面板主体2的透光率，进而提高显示面板底部的拍摄效果。
本申请实施例通过在面板主体的衬底和金属走线之间设置遮光层，以在光源组件通过背光单元向面板主体提供光源时，避免进入至面板主体的光束通过金属走线反射至显示面板的底部，提高显示面板底部的拍摄效果。
相应的，本发明实施例还提供一种显示装置。
如图6所示，本发明实施例提供的显示装置包括摄像组件3以及显示面板100，所述显示面板100为上述实施例中的显示面板，在此不再详细赘述。
所述摄像组件3位于所述背光单元11背离所述面板主体2的一侧，且与所述透光部13相对应，即摄像组件3在背光单元11上的正投影位于透光部13内。在摄像组件3中的摄像头开启时，第二光源122可以关闭，以保证摄像组件3的感光器能够接收到外部光，保证摄像组件的正常拍摄；在摄像组件3中的摄像头未开启时，第二光源122可以开启，以保证显示面板的正常显示。
本实施例中的所述显示装置可以为手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
综上，本申请实施例通过在面板主体的衬底和金属走线之间设置遮光层，以在光源组件通过背光单元向面板主体提供光源时，避免进入至面板主体的光束通过金属走线反射至显示面板的底部，提高显示面板底部的摄像组件的拍摄效果。
综上所述，虽然本申请已以优选实施例揭露如上，但上述优选实施例并非用以限制本申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为准。
