技术领域
本公开涉及显示技术领域，尤指一种显示面板及显示装置。
背景技术
随着显示技术的迅速发展，镜面显示技术越来越受到人们的推崇。镜面显示器既可以实现显示功能，又可以作为镜面使用，给用户提供了很大的便利。有机发光二极管(Organic Light Emitting Diode，OLED)显示面板具有低能耗、生产成本低、自发光、宽视角及响应速度快等优点，被广泛应用在镜面显示领域中。
在OLED镜面显示面板中，镜面反射层中具有多个开口区域，开口区域可以透射发光器件出射的光线，以实现画面显示，镜面反射层中的非开口区域可以作为镜面使用。然而，由于镜面反射层中开口区域与非开口区域之间的段差较大，使得显示面板的表面不平整，在镜面反射层之上贴附光学胶等膜层时，容易产生气泡，导致显示面板的良率较低。

具体实施方式
图1为相关技术中OLED镜面显示面板在制作过程中的结构示意图，参照图1，在OLED镜面显示面板的制作过程中，采用封装层对发光器件进行封装，在封装层上方形成镜面反射层11，并对镜面反射层11进行图形化形成 多个开口区域U。为了更清楚的示意，图1中以四个开口区域U为例进行示意，不对开口区域U的形状、尺寸和数量进行限定。发光器件出射的光线可以通过镜面反射层11的开口区域U射出，以实现画面显示，镜面反射层11中的非开口区域可以作为镜面。
在镜面反射层11制作完成后，需要在镜面反射层11的表面贴附光学胶12及盖板等膜层，例如，在贴附光学胶12的过程中，可以采用辊轮13将光学胶12铺平。由于镜面反射层11中具有多个开口区域U，开口区域U与非开口区域之间的段差较大，使得显示面板的表面不平整。在光学胶12的贴附过程中，开口区域U中会残留一些空气，使得贴附完成后，光学胶12表面出现褶皱。并且，由于开口区域U的边缘对光学胶12的支撑作用，使得光学胶12在开口区域U处悬空，导致手指按压在显示面板的表面时，显示面板容易出现形变。此外，在后续进行信赖性测试时，在高温高湿的环境下，显示面板的表面容易出现气泡q，影响显示良率。
基于此，本公开实施例提供了一种显示面板及显示装置。
下面结合附图，对本公开实施例提供的显示面板及显示装置的具体实施方式进行详细地说明。附图中各膜层的厚度和形状不反映真实比例，目的只是示意说明本发明内容。
图2为本公开实施例提供的显示面板的结构示意图，如图2所示，本公开实施例提供的显示面板，可以包括：
衬底基板20；
多个发光器件21，位于衬底基板20之上；
封装层22，覆盖各发光器件21；
镜面层23，位于封装层22背离衬底基板20的一侧；镜面层23包括：多个第一开口U1；第一开口U1在衬底基板20上的正投影与至少一个发光器件21在衬底基板20上的正投影具有交叠区域；
透明填充层24，位于封装层22背离衬底基板20的一侧；
镜面层23中的第一开口U1内具有至少部分透明填充层24。
本公开实施例提供的显示面板中，通过在封装层背离衬底基板的一侧设置透明填充层，并且镜面层中的第一开口内具有至少部分透明填充层，减小了镜面层中第一开口与非开口区域之间的段差，使显示面板的表面比较平整，因而，后续在镜面层之上贴附粘合层(例如光学胶)及盖板等膜层时，显示面板表面的膜层(例如粘合层)不容易出现褶皱或气泡等不良，提高了显示面板的显示良率。
本公开实施例提供的显示面板可以为有机发光二极管显示面板，参照图2，本公开实施例中的显示面板可以包括多个发光器件21，为了清楚的示意本公开实施例中各膜层的结构，图2中仅示出了一个发光器件21，在具体实施时，可以根据实际需要设置发光器件21的数量及分布，此处不做限定。发光器件21可以包括：第一电极211、位于第一电极211背离衬底基板20一侧的第二电极212，以及位于第一电极211与第二电极212之间的有机发光层213；其中，第一电极211为阳极，第二电极212为阴极；或者，第一电极211为阴极，第二电极212为阳极。可选地，各发光器件21中的第一电极211可以分立设置，即每一个发光器件21中可以设置一个独立的第一电极211，各发光器件21可以共用一个第二电极212，即第二电极212可以为整面设置。
继续参照图2，本公开实施例提供的显示面板还可以包括：位于发光器件21背离衬底基板20一侧的封装层22，封装层22覆盖显示面板中的多个发光器件21，防止发光器件21被水汽和氧气侵蚀。
本公开实施例中，如图2所示，通过在封装层22背离衬底基板20的一侧设置镜面层23，镜面层23与显示面板的显示面之间的距离较近，可以实现较好的镜面效果。镜面层23包括多个第一开口U1，且第一开口U1在衬底基板20上的正投影与至少一个发光器件21在衬底基板20上的正投影具有交叠区域，从而，可以使发光器件21出射的光线通过第一开口U1射出，以实现画面显示。镜面层23中除第一开口U1以外的区域(即非开口区域)可以反射光线，因而，镜面层23的非开口区域可以作为镜面使用。这样，可以使显示面板同时实现显示和镜面的作用，用户在观看显示画面的同时，也可以观 看到显示面板反射的画面，从而满足用户的多种需求。本公开实施例提供的显示面板可以应用于多种场景中，例如，可以应用在公共场所广告屏、车载后视镜、取款机显示屏等场景中。此外，外界光线无法穿过镜面层23射向显示面板内部，因而，发光器件21出射的光线不受外界光线的影响，提高了显示面板的对比度。
在实际应用中，继续参照图2，可以采用高反射率的金属材料制作上述镜面层23，例如，可以采用铝或银制作上述镜面层23，此外，镜面层23也可以包括叠层设置的至少两层金属层，例如镜面层23可以包括钛/铝/钛金属层。在实际工艺过程中，可以采用低温溅射工艺在封装层22之上沉积金属层，然后采用一道构图工艺，对该金属层进行图形化，形成具有多个第一开口U1的镜面层23。当然，也可以采用其他高反射率的材料制作上述镜面层23，此处不做限定。可选地，镜面层23的厚度可以在200nm～500nm之间，优选为在200nm～350nm之间，例如镜面层23的厚度可以在310nm左右。
图3为本公开实施例提供的显示面板在制作过程中的结构示意图，结合图2和图3，本公开实施例中，通过在封装层22背离衬底基板20的一侧设置透明填充层24，并且镜面层23中的第一开口U1内具有至少部分透明填充层24，从而减小镜面层23中第一开口U1与非开口区域之间的段差，使显示面板的表面比较平整。后续在镜面层23的表面贴附粘合层27等膜层时，粘合层27等膜层不容易出现褶皱或气泡等不良。如图3所示，可以采用辊轮13将粘合层27铺平，从图3可以明显看出，粘合层27的表面比较平整，没有出现褶皱或气泡等不良。
此外，如图2所示，由于透明填充层24是透明的，发光器件21出射的光线能够穿过透明填充层24，因而，透明填充层24不会影响显示面板的显示效果。
在本公开实施例中，透明填充层至少存在以下两种设置方式，以下结合附图进行详细说明。
方式一：
如图2所示，本公开实施例提供的上述显示面板中，透明填充层24可以包括：第一透明填充层241和第二透明填充层242，第二透明填充层242位于镜面层23背离衬底基板20的一侧；
第一透明填充层241可以包括：多个分立设置的填充部241＇，图中为了清楚的示意透明填充层24的结构，仅示意出一个填充部241＇，在实际应用中，可以在多个第一开口U1的位置处设置填充部241＇；
部分填充部241＇位于第一开口U1内，且填充部241＇背离衬底基板20一侧的表面，与第二透明填充层242背离衬底基板20一侧的表面大致平齐，其中，大致平齐指的是：填充部241＇背离衬底基板20一侧的表面，与第二透明填充层242背离衬底基板20一侧的表面的距离可以在一定偏差范围内，例如二者的距离可以小于30nm，也就是说，透明填充层24背离衬底基板20一侧的表面大致平坦，可以具有小于30nm的范围内起伏。
本公开实施例中，第一透明填充层241中具有多个填充部241＇，填充部241＇可以填充第一开口U1，可选地，第一透明填充层241中的多个填充部241＇可以与镜面层23中的多个第一开口U1一一对应，从而通过透明填充层24填充镜面层23中的各第一开口U1，并且，填充部241＇在垂直于衬底基板20方向上的厚度，可以与镜面层23和第二透明填充层242在垂直于衬底基板20方向上的总厚度一致，从而使填充部241＇的填充效果较好，并且，可以使透明填充层24背离衬底基板20一侧的表面为平坦面，这样，透明填充层24还可以起到平坦化的作用，使显示面板的表面更加平坦。此外，透明填充层24还可以起到保护镜面层23的作用，防止后续工艺对镜面层23的表面造成损伤。
在具体实施时，本公开实施例提供的上述显示面板中，继续参照图2，上述透明填充层24可以包括：有机材料，例如该有机材料可以为树脂材料。可选地，可以将透明填充层24中的第一透明填充层241与第二透明填充层242设置为一体结构，这样透明填充层24更容易制作。在制作过程中，在镜面层23之上涂布有机材料，由于有机材料具有较好的流平效果，能够填充镜面层 23中的各第一开口U1，并覆盖镜面层23的非开口区域，以形成透明填充层24。并且，有机材料的平坦化效果较好，从而使形成的透明填充层24背离衬底基板20一侧的表面为平坦面。
可选地，第一透明填充层241的厚度可以在200nm～1000nm的范围内，优选为在300nm～600nm的范围内，例如，第一透明填充层241的厚度可以在560nm左右，第二透明填充层242的厚度可以在200nm～400nm之间，例如第二透明填充层242的厚度可以在310nm左右。
方式二：
图4为本公开实施例提供的显示面板的另一结构示意图，如图4所示，本公开实施例提供的上述显示面板中，透明填充层24可以包括：多个分立设置的填充部241＇；
填充部241＇位于第一开口U1内，且填充部241＇背离衬底基板20一侧的表面与镜面层23背离衬底基板20一侧的表面大致平齐。其中，大致平齐指的是：填充部241＇背离衬底基板20一侧的表面，与镜面层23背离衬底基板20一侧的表面的距离可以在一定偏差范围内，例如二者的距离可以小于30nm。
本公开实施例中，透明填充层24可以包括多个分立设置的填充部241＇，填充部241＇可以填充第一开口U1。可选地，透明填充层24中的多个填充部241＇可以与镜面层23中的多个第一开口U1一一对应，从而通过透明填充层24填充镜面层23中的各第一开口U1。并且，填充部241＇背离衬底基板20一侧的表面与镜面层23背离衬底基板20一侧的表面大致平齐，从而使镜面层23背离衬底基板20一侧的表面比较平整。在具体实施时，可以根据镜面层23的厚度设置填充部241＇的厚度，以使填充部241＇能够填平第一开口U1。
在具体实施时，本公开实施例提供的上述显示面板中，继续参照图4，填充部241＇可以包括：无机材料，例如该无机材料可以为二氧化硅材料或氮化硅材料。在制作过程中，可以采用化学气相沉积工艺，在镜面层23之上沉积 与镜面层23的厚度一致的无机层，然后采用一道构图工艺对该无机层进行图形化，去除非开口区域的无机层，从而在各第一开口U1内形成多个填充部241＇。
在实际应用中，本公开实施例提供的上述显示面板中，上述透明填充层的透过率大于90％，采用高透过率的材料制作透明填充层，可以保证发光器件出射的光线能够穿过透明填充层，透明填充层不会影响显示面板的显示效果。当然，透明填充层的透过率也可以小于90％，可以根据实际需要进行设置，此处不做限定。
图5为图2的局部放大示意图，为了清楚的示意封装层的结构，图5中仅示意出封装层、镜面层及透明填充层，省略了其他膜层。如图2和图5所示，封装层22可以包括：层叠设置的无机膜层221及有机膜层222，其中，无机膜层221可以起到阻隔水汽和氧气的作用，有机膜层222可以位于相邻的两层无机膜层221之间，可以起到释放应力及平坦化的作用。与镜面层23距离最近的无机膜层221中，该无机膜层221在第一开口U1位置处的厚度h1，小于该无机膜层221在镜面层23的图形位置处的厚度h2，即该无机膜层221在发光器件21的位置处的厚度h1较薄，这样，该无机膜层221对发光器件21出射的光线的影响较小，可以提高显示面板的光透过率。在实际工艺过程中，可以调整镜面层23的工艺参数，在对镜面层23进行刻蚀的过程中，可在第一开口U1的位置处发生过刻，以使该无机膜层221在发光器件21的位置处的厚度h1较薄。可选地，封装层22的总厚度可以在500nm～800nm的范围内，其中，封装层22在第一开口U1位置处的厚度可以在540nm左右，封装层22在镜面层23的图形位置处的厚度可以在610nm左右。
图5中为了清楚的示意与镜面层23距离最近的无机膜层221的结构，将该无机膜层221的厚度示意的较厚，在具体实施时，可以根据实际需要来设置封装层22中各无机膜层221的厚度，此处不做限定。并且，图5中以透明填充层24为上述方式一的结构为例进行示意，当透明填充层24为上述方式二的结构时，也可以将与镜面层23距离最近的无机膜层221设置为：该无机 膜层221在第一开口U1位置处的厚度h1，小于该无机膜层221在镜面层23的图形位置处的厚度h2。
在具体实施时，本公开实施例提供的上述显示面板中，如图2和图4所示，在衬底基板20指向镜面层23的方向上，第一开口U1在平行于衬底基板20的方向上的截面面积呈逐渐增大的趋势，也就是说，第一开口U1的侧壁为斜面，这样，可以使发光器件21出射的光线经第一开口U1的侧壁反射后射出，提高显示面板的出光效率。
如图2所示，本公开实施例提供的上述显示面板中，还可以包括：位于衬底基板20与封装层22之间的像素界定层25；
像素界定层25可以包括：与各发光器件21一一对应的多个第二开口U2；
镜面层23中的多个第一开口U1与各第二开口U2一一对应。
在本公开实施例中，显示面板可以包括多个子像素，像素界定层用于界定各子像素的区域，即第二开口U2的位置对应一个子像素。将镜面层23中的多个第一开口U1设置为与各第二开口U2一一对应，一方面，可以保证每一个发光器件21出射的光线可以穿过对应的第一开口U1，保证显示面板具有较好的显示效果，另一方面，可以使镜面层23的非开口区域的面积较大，使显示面板的镜面效果较好。
图6为本公开实施例中第一开口与第二开口的对应关系示意图，如图6中的(1)和(2)，本公开实施例提供的显示面板中，第二开口U2在衬底基板上的正投影，位于对应的第一开口U1在衬底基板上的正投影的范围内，也就是说，镜面层中的第一开口U1的尺寸大于对应的第二开口U2的尺寸，或者，镜面层中的第一开口U1的尺寸与对应的第二开口U2的尺寸相当，这样，发光器件出射的光线不会被镜面层遮挡，因而，镜面层不会影响显示面板的开口率，显示面板的显示效果较好。
此外，如图6中的(3)，也可以将第一开口U1在衬底基板上的正投影，设置为位于对应的第二开口U2在衬底基板上的正投影，也就是说，镜面层中的第一开口U1的尺寸小于对应的第二开口U2的尺寸，这样，虽然镜面层中 各第一开口U1的边缘会遮挡发光器件出射的部分光线，但是可以提高显示面板的反射率，即提高显示面板的镜面效果。
在具体实施时，可以将第一开口U1的形状设置为与第二开口U2的形状相同，例如图6中，第一开口U1与第二开口U2的形状均为六边形，在具体实施时，第一开口U1和第二开口U2也可以为其他形状，此处不做限定。
图7为镜面层的开口率与显示面板的镜面反射率的对应关系示意图，如图7所示，曲线L1为设置镜面层的显示面板对应的关系曲线，曲线L2为未设置镜面层的显示面板对应的关系曲线。可以理解的是，镜面层的开口率指的是，镜面层中第一开口的面积与对应的子像素的总面积的比值。从图7可以看出，对于设置镜面层的显示面板，随着镜面层的开口率的增大，镜面层中第一开口的总面积增大，镜面层的非开口区域的总面积减小，因而显示面板的镜面反射率逐渐降低。对于未设置镜面层的显示面板，显示面板的镜面反射率均较低。
在实际应用中，可以采用测试光源和亮度计来检测显示面板的镜面反射率，具体地，可以将测试光源和亮度计设置在显示面板的显示面一侧的设定位置，以使测试光源出射的光线射向显示面板的显示面，并经显示面板的显示面反射至亮度计，根据测试光源的出射光亮度及亮度计检测的亮度值，来确定显示面板的镜面反射率。在具体实施时，可以将显示面板的镜面反射率设置为大于50％，例如可以设置为在85％～97％之间，将显示面板的透过率设置在46％～81％之间，可以根据实际场景，即根据显示面板所需的镜面反射率的大小，来设置镜面反射层中第一开口的尺寸。
一般像素界定层的开口率可以在15％～30％的范围内，优选为20％～26％的范围内，例如，可以将像素界定层的开口率设置为21％左右，像素界定层的开口率可以理解为，像素界定层中第二开口的面积与对应的子像素的总面积的比值。像素界定层中第二开口的宽度可以设置在8μm～25μm的范围内，优选为10μm～20μm的范围内，例如第二开口的宽度可以设置为15μm左右，镜面层中第一开口的宽度可以设置在7μm～23μm的范围内。或者，可以将 第一开口的面积与第二开口的面积的比值设置在0.38～1.89的范围内。
在实际应用中，如图2所示，为了驱动各发光器件21发光，上述显示面板还可以包括：薄膜晶体管TFT及电容结构(图中未示出)等部件，其中，薄膜晶体管TFT可以包括：有源层Ac、源极S、漏极D，以及栅极Ga，薄膜晶体管TFT的漏极D与第一电极211耦接。并且，为了使不同膜层的导电部件相互绝缘，上述显示面板还可以包括：位于有源层Ac与栅极Ga之间的第一栅极绝缘层GI1，位于栅极Ga与源极S之间的第二栅极绝缘层GI2及层间绝缘层ILD，位于源极S与第一电极211之间的平坦层PLN，以及位于有源层Ac与衬底基板20之间的缓冲层29。此外，显示面板还可以包括位于源极S与平坦层PLN之间的钝化层(图中未示出)，以保护源极S及漏极D，防止源极S及漏极D被氧化。
图8为本公开实施例提供的显示面板的另一结构示意图，如图8所示，本公开实施例提供的上述显示面板中，还可以包括：形成于透明填充层24背离衬底基板20一侧的触控电极层26＇。这样，可以使显示面板实现触控功能，且触控电极层26＇与显示面板的显示面距离较近，显示面板的触控效果较好。在实际工艺过程中，可以将触控电极层26＇直接形成在透明填充层24之上，通过构图工艺形成多个触控电极。此外，上述显示面板还可以包括：盖板28，以及位于盖板28与触控电极层26＇之间的粘合层27。盖板28可以保护显示面板的内部结构，粘合层27可以将盖板28粘合在触控电极层26＇的表面。
图9为本公开实施例提供的显示面板的俯视结构示意图，如图9所示，本公开实施例提供的上述显示面板中，触控电极层可以包括：由金属网格构成的多个触控电极261；
触控电极261在衬底基板上的正投影，位于像素界定层25的图形在衬底基板上的正投影的范围内，即触控电极261中的金属网格在衬底基板上的正投影，与像素界定层25中的各第二开口U2在衬底基板上的正投影互不交叠。
这样，触控电极不会遮挡发光器件出射的光线，不会影响显示面板的显示效果。
如图2所示，在另一些实施例中，上述显示面板，还可以包括：位于透明填充层24背离衬底基板20一侧的触控模组26，以及位于触摸模组26与透明填充层24之间的粘合层27，例如，粘合层27可以为光学胶。在实际工艺过程中，可以将粘合层27贴附在透明填充层24的表面，然后，在粘合层27的表面贴附触控模组26，通过粘合层27可以将触控模组26粘合在透明填充层24的表面。在本公开实施例中，由于镜面层23中的第一开口U1内具有至少部分透明填充层24，因而，在透明填充层24之上形成的粘合层27不会出现褶皱或气泡等不良，显示面板的良率较高。
可选地，触控模组26可以包括多个触控电极，触控电极可以采用透明导电材料制作，例如可以采用氧化铟锡(Indium tin oxide，ITO)材料，这样，触控模组不会遮挡发光器件出射的光线，不会影响显示面板的显示效果。
此外，继续参照图2，本公开实施例提供的上述显示面板，还可以包括：盖板28，以及位于盖板28与触控模组26之间的粘合层27。盖板28可以保护显示面板的内部结构，粘合层27可以将盖板28粘合在触控模组26的表面。
图10为本公开实施例提供的显示面板的像素排布示意图，如图10所示，本公开实施例提供的上述显示面板可以包括：在第一方向F1和第二方向F2呈阵列排布的多个重复单元W；第一方向F1与第二方向F2相互交叉，例如第一方向F1与第二方向F2可以相互垂直；
重复单元W可以包括四个子像素，分别为：一个第一子像素P1、一个第二子像素P2，以及两个第三子像素P3；每一个子像素内设有一个发光器件；
在每一个重复单元W中，第一子像素P1与第二子像素P2沿第一方向F1延伸且沿第二方向F2排列，第三子像素P3位于第一子像素P1与第二子像素P2之间。可选地，第一子像素P1可以为蓝色子像素，第二子像素P2可以为红色子像素，第三子像素P3可以为绿色子像素，在具体实施时，可以根据实际需要对各子像素的颜色进行调整，此处不对各子像素的颜色进行限定。在实际应用中，同一重复单元W中的子像素可以对应一个显示像素，或者，不同重复单元W中的子像素可以对应一个显示像素，可以根据实际显示需要进 行设置，此处不做限定。
可选地，在重复单元W内，第一子像素P1和第二子像素P2的形状可以为六边形，第三子像素P3的形状可以为五边形，或者，第一子像素P1、第二子像素P2及第三子像素P3也可以为其他形状，此处不做限定。本公开实施例中，上述像素界定层中的第二开口的形状可以与对应的子像素的形状一致，在具体实施时，可以根据子像素的形状，来设置对应的第二开口的形状。
在实际应用中，本公开实施例提供的上述显示面板中，上述镜面层中的多个第一开口与各重复单元一一对应。这样，镜面层不会遮挡重复单元内各子像素的出射光线，使显示面板的显示效果较好。
图11为本公开实施例提供的显示面板的另一结构示意图，如图11所示，本公开实施例提供的上述显示面板中，还可以包括：位于镜面层23与封装层22之间的透明保护层30。在制作过程中，透明保护层30可以保护下层膜层，避免对镜面层23进行图形化的过程中，损伤下层膜层，并且，发光器件21出射的光线可以穿过透明保护层30，不会影响显示面板的显示效果。在具体实施时，在显示面板的边缘处，透明保护层的边缘可以超出封装层及镜面层的边缘，以对下层膜层进行有效的保护。
一般在显示面板的边缘设有绑定区域，绑定区域内设有多个焊盘，可以通过焊盘与柔性电路板、集成芯片等器件绑定连接，以实现显示面板与柔性电路板或集成芯片等器件之间的信号传输。并且，显示面板还包括：多条信号引线，焊盘可以通过信号引线与发光器件或触控电极耦接。然而，在显示面板的边缘处，部分信号引线没有被封装层覆盖，这部分信号引线之上仅设有绝缘薄膜，因而，在镜面层的图形化过程中，存在损伤这部分信号引线的风险。本公开实施例中，透明保护层可以覆盖信号引线，并露出焊盘，以对信号引线进行保护，防止镜面层图形化的过程中，发生过刻而损伤信号引线。
可选地，透明保护层30可以采用氮化硅SiNx、氧化硅SiOx或SiNx/SiOx的复合材料制作，或者，透明保护层30也可以采用其他透明材料制作，此处不做限定。透明保护层30的厚度可以设置在0.2μm～0.4μm的范围内，或者， 透明保护层30的厚度也可以设置在其他范围内，此处不做限定。
由于镜面层通常采用高反射率的金属材料制作，因而，在对显示面板进行生产、组装、测试或搬运过程中，显示面板内的镜面层容易产生并积累静电，这样容易出现静电放电的现象，进而容易对显示面板的内部结构(例如发光器件或驱动电路等)造成损伤，影响显示面板的正常使用。基于此，本公开实施例提供的显示面板中设置了静电防护部，以对镜面层中的静电进行释放，以下结合附图进行详细说明。
图12为本公开实施例提供的显示面板的俯视结构示意图，如图12所示，本公开实施例提供的上述显示面板中，还可以包括：位于衬底基板20之上且与镜面层23耦接的至少一个静电防护部40；
静电防护部40被配置为对镜面层23中的静电进行释放；
显示面板分为显示区域A及周边区域B；镜面层23位于显示区域A内，静电防护部40位于周边区域B内。
本公开实施例中，通过在衬底基板20之上设置与镜面层23耦接的至少一个静电防护部40，静电防护部40可以对镜面层23中的静电进行释放，从而，可以避免镜面层23中产生静电积累，进而，可以避免出现静电放电现象，防止静电放电过程对显示面板的内部结构造成损伤。并且，将静电防护部40设置在周边区域B内，静电防护部40不会占用显示面板的显示区域A的面积，使得显示面板具有较大的屏占比。此外，镜面层23设置在显示区域A内，可以使显示面板的镜面效果较好，当然，镜面层23的边缘也可以稍微超出显示区域A，此处不做限定。
在本公开实施例中，上述静电防护部可以具有多种实现方式，以下结合附图进行详细说明。
实现方式一：
在一些实施例中，如图12所示，本公开实施例提供的上述显示面板中，静电防护部40可以包括：导电连接部401；
周边区域B内设有固定电压信号端411，导电连接部401与固定电压信号 端411耦接。
这样，导电连接部401可以将镜面层23产生的静电传输至固定电压信号端411，以将镜面层23中的静电导走。
此外，同样参照图12，上述显示面板还可以包括：位于衬底基板20之上的固定电压信号线41，例如固定电压信号线41可以为低电位电压信号线。固定电压信号线41可以围绕显示区域A，或者，固定电压信号线41可以位于显示区域A的一侧，导电连接部401与固定电压信号线41耦接。这样，导电连接部401可以将镜面层23产生的静电传输至固定电压信号线41，以将镜面层23中的静电导走。
在具体实施时，周边区域B包括绑定区域B1，绑定区域B1绑定区域内设有多个焊盘42，焊盘42用于与柔性电路板、集成芯片等器件绑定连接。上述导电连接部401可以设置在绑定区域B1内。
可选地，本公开实施例提供的上述显示面板中，继续参照图12，镜面层23可以包括：金属材料，导电连接部401与镜面层23为一体结构，也就是说，镜面层23与导电连接部401的图形是连续的，镜面层23与导电连接部401无需采用搭接方式或其他方式耦接，因而，镜面层23与导电连接部401的连接效果较好。并且，在制作过程中，可以采用同一次构图工艺制作镜面层23和导电连接部401，降低制作成本。
实现方式二：
图13为本公开实施例提供的显示面板的另一俯视结构示意图，图14为本公开实施例中静电防护部的结构示意图，如图13和图14所示，在另一些实施例中，本公开实施例提供的上述显示面板中，还可以包括：第一电压信号端K1，以及第二电压信号端K2，可选地，第一电压信号端K1和第二电压信号端K2可以设置在周边区域B内。其中，第一电压信号端K1用于传输第一电压信号，第二电压信号端K2用于传输第二电压信号，第一电压信号的电压高于第二电压信号的电压；或者，第一电压信号的电压低于第二电压信号的电压，在本公开实施例中，均以第一电压信号的电压高于第二电压信号的 电压为例进行说明，并以VGH表示第一电压信号，以VGL表示第二电压信号；
如图14中的(1)，上述静电防护部40可以包括：第一晶体管TFT1，以及第二晶体管TFT2，第一晶体管TFT1和第二晶体管TFT2可以为P型晶体管也可以为N型晶体管，在本公开实施例中以第一晶体管TFT1和第二晶体管TFT2均为P型晶体管为例进行说明。
第一晶体管TFT1的控制端Ga1与第一端S1耦接，第一晶体管TFT1的第一端S1与第一电压信号端K1耦接，第一晶体管TFT1的第二端D1与第二晶体管TFT2的第一端S2耦接；
第二晶体管TFT2的控制端Ga2与第一端S2耦接，第二晶体管TFT2的第二端D2与第二电压信号端K2耦接；
镜面层23与第一晶体管TFT1的第二端D1耦接。
如图14中的(2)，第一晶体管TFT1的控制端Ga1与第一端S1耦接，可以将第一晶体管TFT1等效为二极管，即第一二极管，第一晶体管TFT1的控制端Ga1和第一端S1共同等效为第一二极管的阴极，第一晶体管TFT1的第二端D1等效为第一二极管的阳极。第二晶体管TFT2的控制端Ga2与第一端S2耦接，可以将第二晶体管TFT2等效为二极管，即第二二极管，第二晶体管TFT2的控制端Ga2和第一端S2共同等效为第二二极管的阴极，第二晶体管TFT2的第二端D2等效为第二二极管的阳极。
在具体实施时，镜面层23中产生的静电可能是正静电，也可能是负静电。当镜面层23中产生的静电为正静电，且静电层23中产生的静电的电压高于第一电压信号VGH的电压时，此时，第一晶体管TFT1导通，第二晶体管TFT2截止，第一晶体管TFT1将静电传输至第一电压信号端K1。当镜面层23中产生的静电为负静电，且静电层23中产生的静电的电压低于第二电压信号VGL的电压时，第一晶体管TFT1截止，第二晶体管TFT2导通，第二晶体管TFT2将静电传输至第二电压信号端K2。这样，无论镜面层23中产生的静电为正静电还是负静电，静电防护部40均可以将静电释放，防止静电放电损伤显示 面板的内部结构。
在实际应用中，本公开实施例提供的上述显示面板中，如图13所示，显示面板包括多个静电防护部40，各静电防护部40均匀分布于镜面层23的四周。例如，图13中，显示区域A为矩形，显示面板包括四个静电防护部40，各静电防护部40分别位于显示区域A的四个角对应的位置处。此外，显示面板中的静电防护部40也可以为其他数量，并且，可以根据实际情况，设置各静电防护部40的分布情况，此处不做限定。
实现方式三：
图15为本公开实施例提供的显示面板的另一俯视结构示意图，如图15所示，本公开实施例中，还可以将上述实现方式一与实现方式二进行结合，也就是说，可以在周边区域B内设置与镜面层23耦接的导电连接部401，并且，在周边区域B内设置与第一电压端K1、第二电压端K2耦接的静电防护部40，在具体实施时，可以根据实际需要进行设置，此处不再一一举例。
基于同一发明构思，本公开实施例还提供了另一种显示面板，图2为本公开实施例提供的显示面板的结构示意图，如图2所示，本公开实施例提供的显示面板，可以包括：
衬底基板20；
多个发光器件21，位于衬底基板20之上；
封装层22，覆盖各发光器件21；
反射结构层23＇，位于封装层22背离衬底基板20的一侧；反射结构层23＇包括：多个第一开口U1；第一开口U1在衬底基板20上的正投影与至少一个发光器件21在衬底基板20上的正投影具有交叠区域；
透明填充层24，位于封装层22背离衬底基板20的一侧；
反射结构层23＇中的第一开口U1内具有至少部分透明填充层24。
本公开实施例提供的显示面板中，通过在封装层背离衬底基板的一侧设置透明填充层，并且反射结构层中的第一开口内具有至少部分透明填充层，减小了反射结构层中第一开口与非开口区域之间的段差，使显示面板的表面 比较平整，因而，后续在反射结构层之上贴附粘合层(例如光学胶)及盖板等膜层时，显示面板表面的膜层(例如粘合层)不容易出现褶皱或气泡等不良，提高了显示面板的显示良率。
本公开实施例提供的显示面板可以为有机发光二极管显示面板，参照图2，本公开实施例中的显示面板可以包括多个发光器件21，为了清楚的示意本公开实施例中各膜层的结构，图2中仅示出了一个发光器件21，在具体实施时，可以根据实际需要设置发光器件21的数量及分布，此处不做限定。发光器件21可以包括：第一电极211、位于第一电极211背离衬底基板20一侧的第二电极212，以及位于第一电极211与第二电极212之间的有机发光层213；其中，第一电极211为阳极，第二电极212为阴极；或者，第一电极211为阴极，第二电极212为阳极。可选地，各发光器件21中的第一电极211可以分立设置，即每一个发光器件21中可以设置一个独立的第一电极211，各发光器件21可以共用一个第二电极212，即第二电极212可以为整面设置。
继续参照图2，本公开实施例提供的显示面板还可以包括：位于发光器件21背离衬底基板20一侧的封装层22，封装层22覆盖显示面板中的多个发光器件21，防止发光器件21被水汽和氧气侵蚀。
本公开实施例中，如图2所示，通过在封装层22背离衬底基板20的一侧设置反射结构层23＇，反射结构层23＇与显示面板的显示面之间的距离较近，可以实现较好的镜面效果。反射结构层23＇包括多个第一开口U1，且第一开口U1在衬底基板20上的正投影与至少一个发光器件21在衬底基板20上的正投影具有交叠区域，从而，可以使发光器件21出射的光线通过第一开口U1射出，以实现画面显示。反射结构层23＇中除第一开口U1以外的区域(即非开口区域)可以反射光线，因而，反射结构层23＇的非开口区域可以作为镜面使用。这样，可以使显示面板同时实现显示和镜面的作用，用户在观看显示画面的同时，也可以观看到显示面板反射的画面，从而满足用户的多种需求。本公开实施例提供的显示面板可以应用于多种场景中，例如，可以应用在公共场所广告屏、车载后视镜、取款机显示屏等场景中。此外，外 界光线无法穿过反射结构层23＇射向显示面板内部，因而，发光器件21出射的光线不受外界光线的影响，提高了显示面板的对比度。
在实际应用中，继续参照图2，可以采用高反射率的金属材料制作上述反射结构层23＇，例如，可以采用铝或银制作上述反射结构层23＇，此外，反射结构层23＇也可以包括叠层设置的至少两层金属层，例如反射结构层23＇可以包括钛/铝/钛金属层。在实际工艺过程中，可以采用低温溅射工艺在封装层22之上沉积金属层，然后采用一道构图工艺，对该金属层进行图形化，形成具有多个第一开口U1的反射结构层23＇。当然，也可以采用其他高反射率的材料制作上述反射结构层23＇，此处不做限定。可选地，反射结构层23＇的厚度可以在200nm～500nm之间，优选为在200nm～350nm之间，例如反射结构层23＇的厚度可以在310nm左右。
图3为本公开实施例提供的显示面板在制作过程中的结构示意图，结合图2和图3，本公开实施例中，通过在封装层22背离衬底基板20的一侧设置透明填充层24，并且反射结构层23＇中的第一开口U1内具有至少部分透明填充层24，从而减小反射结构层23＇中第一开口U1与非开口区域之间的段差，使显示面板的表面比较平整。后续在反射结构层23＇的表面贴附粘合层27等膜层时，粘合层27等膜层不容易出现褶皱或气泡等不良。如图3所示，可以采用辊轮13将粘合层27铺平，从图3可以明显看出，粘合层27的表面比较平整，没有出现褶皱或气泡等不良。
此外，如图2所示，由于透明填充层24是透明的，发光器件21出射的光线能够穿过透明填充层24，因而，透明填充层24不会影响显示面板的显示效果。
在本公开实施例中，透明填充层至少存在以下两种设置方式，以下结合附图进行详细说明。
方式一：
如图2所示，本公开实施例提供的上述显示面板中，透明填充层24可以包括：第一透明填充层241和第二透明填充层242，第二透明填充层242位于 反射结构层23＇背离衬底基板20的一侧；
第一透明填充层241可以包括：多个分立设置的填充部241＇，图中为了清楚的示意透明填充层24的结构，仅示意出一个填充部241＇，在实际应用中，可以在多个第一开口U1的位置处设置填充部241＇；
部分填充部241＇位于第一开口U1内，且填充部241＇背离衬底基板20一侧的表面，与第二透明填充层242背离衬底基板20一侧的表面大致平齐，其中，大致平齐指的是：填充部241＇背离衬底基板20一侧的表面，与第二透明填充层242背离衬底基板20一侧的表面的距离可以在一定偏差范围内，例如二者的距离可以小于30nm，也就是说，透明填充层24背离衬底基板20一侧的表面大致平坦，可以具有小于30nm的范围内起伏。
本公开实施例中，第一透明填充层241中具有多个填充部241＇，填充部241＇可以填充第一开口U1，可选地，第一透明填充层241中的多个填充部241＇可以与反射结构层23＇中的多个第一开口U1一一对应，从而通过透明填充层24填充反射结构层23＇中的各第一开口U1，并且，填充部241＇在垂直于衬底基板20方向上的厚度，可以与反射结构层23＇和第二透明填充层242在垂直于衬底基板20方向上的总厚度一致，从而使填充部241＇的填充效果较好，并且，可以使透明填充层24背离衬底基板20一侧的表面为平坦面，这样，透明填充层24还可以起到平坦化的作用，使显示面板的表面更加平坦。此外，透明填充层24还可以起到保护反射结构层23＇的作用，防止后续工艺对反射结构层23＇的表面造成损伤。
在具体实施时，本公开实施例提供的上述显示面板中，继续参照图2，上述透明填充层24可以包括：有机材料，例如该有机材料可以为树脂材料。可选地，可以将透明填充层24中的第一透明填充层241与第二透明填充层242设置为一体结构，这样透明填充层24更容易制作。在制作过程中，在反射结构层23＇之上涂布有机材料，由于有机材料具有较好的流平效果，能够填充反射结构层23＇中的各第一开口U1，并覆盖反射结构层23＇的非开口区域，以形成透明填充层24。并且，有机材料的平坦化效果较好，从而使形成的透 明填充层24背离衬底基板20一侧的表面为平坦面。
可选地，第一透明填充层241的厚度可以在200nm～1000nm的范围内，优选为在300nm～600nm的范围内，例如，第一透明填充层241的厚度可以在560nm左右，第二透明填充层242的厚度可以在200nm～400nm之间，例如第二透明填充层242的厚度可以在310nm左右。
方式二：
图4为本公开实施例提供的显示面板的另一结构示意图，如图4所示，本公开实施例提供的上述显示面板中，透明填充层24可以包括：多个分立设置的填充部241＇；
填充部241＇位于第一开口U1内，且填充部241＇背离衬底基板20一侧的表面与反射结构层23＇背离衬底基板20一侧的表面大致平齐。其中，大致平齐指的是：填充部241＇背离衬底基板20一侧的表面，与反射结构层23＇背离衬底基板20一侧的表面的距离可以在一定偏差范围内，例如二者的距离可以小于30nm。
本公开实施例中，透明填充层24可以包括多个分立设置的填充部241＇，填充部241＇可以填充第一开口U1。可选地，透明填充层24中的多个填充部241＇可以与反射结构层23＇中的多个第一开口U1一一对应，从而通过透明填充层24填充反射结构层23＇中的各第一开口U1。并且，填充部241＇背离衬底基板20一侧的表面与反射结构层23＇背离衬底基板20一侧的表面大致平齐，从而使反射结构层23＇背离衬底基板20一侧的表面比较平整。在具体实施时，可以根据反射结构层23＇的厚度设置填充部241＇的厚度，以使填充部241＇能够填平第一开口U1。
在具体实施时，本公开实施例提供的上述显示面板中，继续参照图4，填充部241＇可以包括：无机材料，例如该无机材料可以为二氧化硅材料或氮化硅材料。在制作过程中，可以采用化学气相沉积工艺，在反射结构层23＇之上沉积与反射结构层23＇的厚度一致的无机层，然后采用一道构图工艺对该无机层进行图形化，去除非开口区域的无机层，从而在各第一开口U1内形成 多个填充部241＇。
在实际应用中，本公开实施例提供的上述显示面板中，上述透明填充层的透过率大于90％，采用高透过率的材料制作透明填充层，可以保证发光器件出射的光线能够穿过透明填充层，透明填充层不会影响显示面板的显示效果。当然，透明填充层的透过率也可以小于90％，可以根据实际需要进行设置，此处不做限定。
图5为图2的局部放大示意图，为了清楚的示意封装层的结构，图5中仅示意出封装层、反射结构层及透明填充层，省略了其他膜层。如图2和图5所示，封装层22可以包括：层叠设置的无机膜层221及有机膜层222，其中，无机膜层221可以起到阻隔水汽和氧气的作用，有机膜层222可以位于相邻的两层无机膜层221之间，可以起到释放应力及平坦化的作用。与反射结构层23＇距离最近的无机膜层221中，该无机膜层221在第一开口U1位置处的厚度h1，小于该无机膜层221在反射结构层23＇的图形位置处的厚度h2，即该无机膜层221在发光器件21的位置处的厚度h1较薄，这样，该无机膜层221对发光器件21出射的光线的影响较小，可以提高显示面板的光透过率。在实际工艺过程中，可以调整反射结构层23＇的工艺参数，在对反射结构层23＇进行刻蚀的过程中，可在第一开口U1的位置处发生过刻，以使该无机膜层221在发光器件21的位置处的厚度h1较薄。可选地，封装层22的总厚度可以在500nm～800nm的范围内，其中，封装层22在第一开口U1位置处的厚度可以在540nm左右，封装层22在反射结构层23＇的图形位置处的厚度可以在610nm左右。
图5中为了清楚的示意与反射结构层23＇距离最近的无机膜层221的结构，将该无机膜层221的厚度示意的较厚，在具体实施时，可以根据实际需要来设置封装层22中各无机膜层221的厚度，此处不做限定。并且，图5中以透明填充层24为上述方式一的结构为例进行示意，当透明填充层24为上述方式二的结构时，也可以将与反射结构层23＇距离最近的无机膜层221设置为：该无机膜层221在第一开口U1位置处的厚度h1，小于该无机膜层221 在反射结构层23＇的图形位置处的厚度h2。
在具体实施时，本公开实施例提供的上述显示面板中，如图2和图4所示，在衬底基板20指向反射结构层23＇的方向上，第一开口U1在平行于衬底基板20的方向上的截面面积呈逐渐增大的趋势，也就是说，第一开口U1的侧壁为斜面，这样，可以使发光器件21出射的光线经第一开口U1的侧壁反射后射出，提高显示面板的出光效率。
如图2所示，本公开实施例提供的上述显示面板中，还可以包括：位于衬底基板20与封装层22之间的像素界定层25；
像素界定层25可以包括：与各发光器件21一一对应的多个第二开口U2；
反射结构层23＇中的多个第一开口U1与各第二开口U2一一对应。
在本公开实施例中，显示面板可以包括多个子像素，像素界定层用于界定各子像素的区域，即第二开口U2的位置对应一个子像素。将反射结构层23＇中的多个第一开口U1设置为与各第二开口U2一一对应，一方面，可以保证每一个发光器件21出射的光线可以穿过对应的第一开口U1，保证显示面板具有较好的显示效果，另一方面，可以使反射结构层23＇的非开口区域的面积较大，使显示面板的镜面效果较好。
图6为本公开实施例中第一开口与第二开口的对应关系示意图，如图6中的(1)和(2)，本公开实施例提供的显示面板中，第二开口U2在衬底基板上的正投影，位于对应的第一开口U1在衬底基板上的正投影的范围内，也就是说，反射结构层中的第一开口U1的尺寸大于对应的第二开口U2的尺寸，或者，反射结构层中的第一开口U1的尺寸与对应的第二开口U2的尺寸相当，这样，发光器件出射的光线不会被反射结构层遮挡，因而，反射结构层不会影响显示面板的开口率，显示面板的显示效果较好。
此外，如图6中的(3)，也可以将第一开口U1在衬底基板上的正投影，设置为位于对应的第二开口U2在衬底基板上的正投影，也就是说，反射结构层中的第一开口U1的尺寸小于对应的第二开口U2的尺寸，这样，虽然反射结构层中各第一开口U1的边缘会遮挡发光器件出射的部分光线，但是可以提 高显示面板的反射率，即提高显示面板的镜面效果。
在具体实施时，可以将第一开口U1的形状设置为与第二开口U2的形状相同，例如图6中，第一开口U1与第二开口U2的形状均为六边形，在具体实施时，第一开口U1和第二开口U2也可以为其他形状，此处不做限定。
图7为反射结构层的开口率与显示面板的镜面反射率的对应关系示意图，如图7所示，曲线L1为设置反射结构层的显示面板对应的关系曲线，曲线L2为未设置反射结构层的显示面板对应的关系曲线。可以理解的是，反射结构层的开口率指的是，反射结构层中第一开口的面积与对应的子像素的总面积的比值。从图7可以看出，对于设置反射结构层的显示面板，随着反射结构层的开口率的增大，反射结构层中第一开口的总面积增大，反射结构层的非开口区域的总面积减小，因而显示面板的镜面反射率逐渐降低。对于未设置反射结构层的显示面板，显示面板的镜面反射率均较低。
在实际应用中，可以采用测试光源和亮度计来检测显示面板的镜面反射率，具体地，可以将测试光源和亮度计设置在显示面板的显示面一侧的设定位置，以使测试光源出射的光线射向显示面板的显示面，并经显示面板的显示面反射至亮度计，根据测试光源的出射光亮度及亮度计检测的亮度值，来确定显示面板的镜面反射率。在具体实施时，可以将显示面板的镜面反射率设置为大于50％，例如可以设置为在85％～97％之间，将显示面板的透过率设置在46％～81％之间，可以根据实际场景，即根据显示面板所需的镜面反射率的大小，来设置镜面反射层中第一开口的尺寸。
一般像素界定层的开口率可以在15％～30％的范围内，优选为20％～26％的范围内，例如，可以将像素界定层的开口率设置为21％左右，像素界定层的开口率可以理解为，像素界定层中第二开口的面积与对应的子像素的总面积的比值。像素界定层中第二开口的宽度可以设置在8μm～25μm的范围内，优选为10μm～20μm的范围内，例如第二开口的宽度可以设置为15μm左右，反射结构层中第一开口的宽度可以设置在7μm～23＇μm的范围内。或者，可以将第一开口的面积与第二开口的面积的比值设置在0.38～1.89的范围内。
在实际应用中，如图2所示，为了驱动各发光器件21发光，上述显示面板还可以包括：薄膜晶体管TFT及电容结构(图中未示出)等部件，其中，薄膜晶体管TFT可以包括：有源层Ac、源极S、漏极D，以及栅极Ga，薄膜晶体管TFT的漏极D与第一电极211耦接。并且，为了使不同膜层的导电部件相互绝缘，上述显示面板还可以包括：位于有源层Ac与栅极Ga之间的第一栅极绝缘层GI1，位于栅极Ga与源极S之间的第二栅极绝缘层GI2及层间绝缘层ILD，位于源极S与第一电极211之间的平坦层PLN，以及位于有源层Ac与衬底基板20之间的缓冲层29。此外，显示面板还可以包括位于源极S与平坦层PLN之间的钝化层(图中未示出)，以保护源极S及漏极D，防止源极S及漏极D被氧化。
图8为本公开实施例提供的显示面板的另一结构示意图，如图8所示，本公开实施例提供的上述显示面板中，还可以包括：形成于透明填充层24背离衬底基板20一侧的触控电极层26＇。这样，可以使显示面板实现触控功能，且触控电极层26＇与显示面板的显示面距离较近，显示面板的触控效果较好。在实际工艺过程中，可以将触控电极层26＇直接形成在透明填充层24之上，通过构图工艺形成多个触控电极。此外，上述显示面板还可以包括：盖板28，以及位于盖板28与触控电极层26＇之间的粘合层27。盖板28可以保护显示面板的内部结构，粘合层27可以将盖板28粘合在触控电极层26＇的表面。
图9为本公开实施例提供的显示面板的俯视结构示意图，如图9所示，本公开实施例提供的上述显示面板中，触控电极层可以包括：由金属网格构成的多个触控电极261；
触控电极261在衬底基板上的正投影，位于像素界定层25的图形在衬底基板上的正投影的范围内，即触控电极261中的金属网格在衬底基板上的正投影，与像素界定层25中的各第二开口U2在衬底基板上的正投影互不交叠。
这样，触控电极不会遮挡发光器件出射的光线，不会影响显示面板的显示效果。
如图2所示，在另一些实施例中，上述显示面板，还可以包括：位于透 明填充层24背离衬底基板20一侧的触控模组26，以及位于触摸模组26与透明填充层24之间的粘合层27，例如，粘合层27可以为光学胶。在实际工艺过程中，可以将粘合层27贴附在透明填充层24的表面，然后，在粘合层27的表面贴附触控模组26，通过粘合层27可以将触控模组26粘合在透明填充层24的表面。在本公开实施例中，由于反射结构层23＇中的第一开口U1内具有至少部分透明填充层24，因而，在透明填充层24之上形成的粘合层27不会出现褶皱或气泡等不良，显示面板的良率较高。
可选地，触控模组26可以包括多个触控电极，触控电极可以采用透明导电材料制作，例如可以采用氧化铟锡(Indium tin oxide，ITO)材料，这样，触控模组不会遮挡发光器件出射的光线，不会影响显示面板的显示效果。
此外，继续参照图2，本公开实施例提供的上述显示面板，还可以包括：盖板28，以及位于盖板28与触控模组26之间的粘合层27。盖板28可以保护显示面板的内部结构，粘合层27可以将盖板28粘合在触控模组26的表面。
图10为本公开实施例提供的显示面板的像素排布示意图，如图10所示，本公开实施例提供的上述显示面板可以包括：在第一方向F1和第二方向F2呈阵列排布的多个重复单元W；第一方向F1与第二方向F2相互交叉，例如第一方向F1与第二方向F2可以相互垂直；
重复单元W可以包括四个子像素，分别为：一个第一子像素P1、一个第二子像素P2，以及两个第三子像素P3；每一个子像素内设有一个发光器件；
在每一个重复单元W中，第一子像素P1与第二子像素P2沿第一方向F1延伸且沿第二方向F2排列，第三子像素P3位于第一子像素P1与第二子像素P2之间。可选地，第一子像素P1可以为蓝色子像素，第二子像素P2可以为红色子像素，第三子像素P3可以为绿色子像素，在具体实施时，可以根据实际需要对各子像素的颜色进行调整，此处不对各子像素的颜色进行限定。在实际应用中，同一重复单元W中的子像素可以对应一个显示像素，或者，不同重复单元W中的子像素可以对应一个显示像素，可以根据实际显示需要进行设置，此处不做限定。
可选地，在重复单元W内，第一子像素P1和第二子像素P2的形状可以为六边形，第三子像素P3的形状可以为五边形，或者，第一子像素P1、第二子像素P2及第三子像素P3也可以为其他形状，此处不做限定。本公开实施例中，上述像素界定层中的第二开口的形状可以与对应的子像素的形状一致，在具体实施时，可以根据子像素的形状，来设置对应的第二开口的形状。
在实际应用中，本公开实施例提供的上述显示面板中，上述反射结构层中的多个第一开口与各重复单元一一对应。这样，反射结构层不会遮挡重复单元内各子像素的出射光线，使显示面板的显示效果较好。
图11为本公开实施例提供的显示面板的另一结构示意图，如图11所示，本公开实施例提供的上述显示面板中，还可以包括：位于反射结构层23＇与封装层22之间的透明保护层30。在制作过程中，透明保护层30可以保护下层膜层，避免对反射结构层23＇进行图形化的过程中，损伤下层膜层，并且，发光器件21出射的光线可以穿过透明保护层30，不会影响显示面板的显示效果。在具体实施时，在显示面板的边缘处，透明保护层的边缘可以超出封装层及反射结构层的边缘，以对下层膜层进行有效的保护。
一般在显示面板的边缘设有绑定区域，绑定区域内设有多个焊盘，可以通过焊盘与柔性电路板、集成芯片等器件绑定连接，以实现显示面板与柔性电路板或集成芯片等器件之间的信号传输。并且，显示面板还包括：多条信号引线，焊盘可以通过信号引线与发光器件或触控电极耦接。然而，在显示面板的边缘处，部分信号引线没有被封装层覆盖，这部分信号引线之上仅设有绝缘薄膜，因而，在反射结构层的图形化过程中，存在损伤这部分信号引线的风险。本公开实施例中，透明保护层可以覆盖信号引线，并露出焊盘，以对信号引线进行保护，防止反射结构层图形化的过程中，发生过刻而损伤信号引线。
可选地，透明保护层30可以采用氮化硅SiNx、氧化硅SiOx或SiNx/SiOx的复合材料制作，或者，透明保护层30也可以采用其他透明材料制作，此处不做限定。透明保护层30的厚度可以设置在0.2μm～0.4μm的范围内，或者， 透明保护层30的厚度也可以设置在其他范围内，此处不做限定。
由于反射结构层通常采用高反射率的金属材料制作，因而，在对显示面板进行生产、组装、测试或搬运过程中，显示面板内的反射结构层容易产生并积累静电，这样容易出现静电放电的现象，进而容易对显示面板的内部结构(例如发光器件或驱动电路等)造成损伤，影响显示面板的正常使用。基于此，本公开实施例提供的显示面板中设置了静电防护部，以对反射结构层中的静电进行释放，以下结合附图进行详细说明。
图12为本公开实施例提供的显示面板的俯视结构示意图，如图12所示，本公开实施例提供的上述显示面板中，还可以包括：位于衬底基板20之上且与反射结构层23＇耦接的至少一个静电防护部40；
静电防护部40被配置为对反射结构层23＇中的静电进行释放；
显示面板分为显示区域A及周边区域B；反射结构层23＇位于显示区域A内，静电防护部40位于周边区域B内。
本公开实施例中，通过在衬底基板20之上设置与反射结构层23＇耦接的至少一个静电防护部40，静电防护部40可以对反射结构层23＇中的静电进行释放，从而，可以避免反射结构层23＇中产生静电积累，进而，可以避免出现静电放电现象，防止静电放电过程对显示面板的内部结构造成损伤。并且，将静电防护部40设置在周边区域B内，静电防护部40不会占用显示面板的显示区域A的面积，使得显示面板具有较大的屏占比。此外，反射结构层23＇设置在显示区域A内，可以使显示面板的镜面效果较好，当然，反射结构层23＇的边缘也可以稍微超出显示区域A，此处不做限定。
在本公开实施例中，上述静电防护部可以具有多种实现方式，以下结合附图进行详细说明。
实现方式一：
在一些实施例中，如图12所示，本公开实施例提供的上述显示面板中，静电防护部40可以包括：导电连接部401；
周边区域B内设有固定电压信号端411，导电连接部401与固定电压信号 端411耦接。
这样，导电连接部401可以将反射结构层23＇产生的静电传输至固定电压信号端411，以将反射结构层23＇中的静电导走。
此外，同样参照图12，上述显示面板还可以包括：位于衬底基板20之上的固定电压信号线41，例如固定电压信号线41可以为低电位电压信号线。固定电压信号线41可以围绕显示区域A，或者，固定电压信号线41可以位于显示区域A的一侧，导电连接部401与固定电压信号线41耦接。这样，导电连接部401可以将反射结构层23＇产生的静电传输至固定电压信号线41，以将反射结构层23＇中的静电导走。
在具体实施时，周边区域B包括绑定区域B1，绑定区域B1绑定区域内设有多个焊盘42，焊盘42用于与柔性电路板、集成芯片等器件绑定连接。上述导电连接部401可以设置在绑定区域B1内。
可选地，本公开实施例提供的上述显示面板中，继续参照图12，反射结构层23＇可以包括：金属材料，导电连接部401与反射结构层23＇为一体结构，也就是说，反射结构层23＇与导电连接部401的图形是连续的，反射结构层23＇与导电连接部401无需采用搭接方式或其他方式耦接，因而，反射结构层23＇与导电连接部401的连接效果较好。并且，在制作过程中，可以采用同一次构图工艺制作反射结构层23＇和导电连接部401，降低制作成本。
实现方式二：
图13为本公开实施例提供的显示面板的另一俯视结构示意图，图14为本公开实施例中静电防护部的结构示意图，如图13和图14所示，在另一些实施例中，本公开实施例提供的上述显示面板中，还可以包括：第一电压信号端K1，以及第二电压信号端K2，可选地，第一电压信号端K1和第二电压信号端K2可以设置在周边区域B内。其中，第一电压信号端K1用于传输第一电压信号，第二电压信号端K2用于传输第二电压信号，第一电压信号的电压高于第二电压信号的电压；或者，第一电压信号的电压低于第二电压信号的电压，在本公开实施例中，均以第一电压信号的电压高于第二电压信号的 电压为例进行说明，并以VGH表示第一电压信号，以VGL表示第二电压信号；
如图14中的(1)，上述静电防护部40可以包括：第一晶体管TFT1，以及第二晶体管TFT2，第一晶体管TFT1和第二晶体管TFT2可以为P型晶体管也可以为N型晶体管，在本公开实施例中以第一晶体管TFT1和第二晶体管TFT2均为P型晶体管为例进行说明。
第一晶体管TFT1的控制端Ga1与第一端S1耦接，第一晶体管TFT1的第一端S1与第一电压信号端K1耦接，第一晶体管TFT1的第二端D1与第二晶体管TFT2的第一端S2耦接；
第二晶体管TFT2的控制端Ga2与第一端S2耦接，第二晶体管TFT2的第二端D2与第二电压信号端K2耦接；
反射结构层23＇与第一晶体管TFT1的第二端D1耦接。
如图14中的(2)，第一晶体管TFT1的控制端Ga1与第一端S1耦接，可以将第一晶体管TFT1等效为二极管，即第一二极管，第一晶体管TFT1的控制端Ga1和第一端S1共同等效为第一二极管的阴极，第一晶体管TFT1的第二端D1等效为第一二极管的阳极。第二晶体管TFT2的控制端Ga2与第一端S2耦接，可以将第二晶体管TFT2等效为二极管，即第二二极管，第二晶体管TFT2的控制端Ga2和第一端S2共同等效为第二二极管的阴极，第二晶体管TFT2的第二端D2等效为第二二极管的阳极。
在具体实施时，反射结构层23＇中产生的静电可能是正静电，也可能是负静电。当反射结构层23＇中产生的静电为正静电，且静电层23＇中产生的静电的电压高于第一电压信号VGH的电压时，此时，第一晶体管TFT1导通，第二晶体管TFT2截止，第一晶体管TFT1将静电传输至第一电压信号端K1。当反射结构层23＇中产生的静电为负静电，且静电层23＇中产生的静电的电压低于第二电压信号VGL的电压时，第一晶体管TFT1截止，第二晶体管TFT2导通，第二晶体管TFT2将静电传输至第二电压信号端K2。这样，无论反射结构层23＇中产生的静电为正静电还是负静电，静电防护部40均可以将静电 释放，防止静电放电损伤显示面板的内部结构。
在实际应用中，本公开实施例提供的上述显示面板中，如图13所示，显示面板包括多个静电防护部40，各静电防护部40均匀分布于反射结构层23＇的四周。例如，图13中，显示区域A为矩形，显示面板包括四个静电防护部40，各静电防护部40分别位于显示区域A的四个角对应的位置处。此外，显示面板中的静电防护部40也可以为其他数量，并且，可以根据实际情况，设置各静电防护部40的分布情况，此处不做限定。
实现方式三：
图15为本公开实施例提供的显示面板的另一俯视结构示意图，如图15所示，本公开实施例中，还可以将上述实现方式一与实现方式二进行结合，也就是说，可以在周边区域B内设置与反射结构层23＇耦接的导电连接部401，并且，在周边区域B内设置与第一电压端K1、第二电压端K2耦接的静电防护部40，在具体实施时，可以根据实际需要进行设置，此处不再一一举例。
基于同一发明构思，本公开实施例还提供了一种显示装置，包括上述显示面板，该显示装置可以应用于手机、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。由于该显示装置解决问题的原理与上述显示面板相似，因此该显示装置的实施可以参见上述显示面板的实施，重复之处不再赘述。
本公开实施例提供的显示面板及显示装置，通过在封装层背离衬底基板的一侧设置透明填充层，可以将镜面层中的第一开口填平，消除镜面层中第一开口与非开口区域之间的段差，使显示面板的表面比较平整，因而，后续在镜面层之上贴附粘合层(例如光学胶)及盖板等膜层时，显示面板表面的膜层(例如粘合层)不容易出现褶皱或气泡等不良，提高了显示面板的显示良率。
尽管已描述了本公开的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本公开范围的所有变更和修改。
显然，本领域的技术人员可以对本公开实施例进行各种改动和变型而不脱离本公开实施例的精神和范围。这样，倘若本公开实施例的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
