技术领域
本申请涉及显示技术领域，特别涉及一种显示组件及其制备方法、显示装置。
背景技术
随着显示技术的发展，用户对于手机等显示装置的功能和效果要求越来越高，为了在保证前置摄像头的功能前提下提高屏占比，挖孔屏越来越受欢迎。目前的挖孔屏一种挖孔屏包括显示面板、偏光片和盖板，其中偏光片具有一个物理通孔，显示面板在偏光片的通孔位置具有透光区域，三者贴合之后，容易导致显示面板在通孔位置产生不平整的印记。
发明内容
一种显示组件及其制备方法、显示装置，能够改善显示面板、偏光片和盖板之间贴合之后容易产生印记的问题，即提高了显示面板的平整度。

在一种可能的实施方式中，偏光片的通孔中填充有胶材。
在一种可能的实施方式中，偏光片的通孔中填充有液体光学胶；
显示组件还包括位于偏光片和盖板之间的胶层，胶层为固体光学胶，偏光片通过固体光学胶粘接于盖板。
在一种可能的实施方式中，显示组件还包括位于偏光片和盖板之间的胶层，胶层为液体光学胶，偏光片通过液体光学胶粘接于盖板，液体光学胶填充于偏光片的通孔中。

具体实施方式
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。
在介绍本申请实施例之前，首先对现有技术的问题发现过程进行说明。如图1和图2所示，现有技术中一种显示组件包括层叠设置的显示面板01、偏光片02和盖板03，为了在保证前置摄像头的功能前提下提高屏占比，设置显示面板01和偏光片02上具有物理通孔04，偏光片02贴附在显示面板01上，再通过胶层05贴附于盖板03上，前者摄像头设置在显示面板01的下方，位于通孔04处，以避免显示面板01和偏光片02对前置摄像头的影响，然而，对显示面板01进行切割制作通孔04的工艺，会导致通孔04周围设置有较大的无法显示区域06。为了降低无法显示区域的面积，以提高屏占比，提出了如图3和图4所示的另一种显示组件采用了盲孔设计，显示组件同样包括层叠设置的显示面板01、偏光片02和盖板03，偏光片02贴附在显示面板01上，再通过胶层05贴附于盖板03上，但是其中的显示面板01上并不设置物理通孔，而是设置一个透光区域07，仅在偏光片02上设置物理通孔04，显示面板01上的透光区域07设置在通孔04所在的位置，其中，显示面板01在透光区域07中不设置电路结构或者尽量少地设置电路结构，以减少显示面板01在透光区域07中的非透光结构，保证前置摄像头的效果。在如图3和图4所示的结构中，由于并不会在显示面板01中通过切割工艺制作物理通孔，而是预留一个和通孔04相对应的透光区域07，在该结构下，显示面板01在通孔04周围所需要设置的无法显示区域的面积较小，从而进一步提高了屏占比，然而，在如图3和图4所示的结构中，由于显示面板01为柔性显示面板01，在显示面板01、偏光片02和盖板03之间相互贴合之后，会由于显示面板01和偏光片02之间的应力作用，导致显示面板01在通孔04位置产生不平整的印记，从而对显示面板01的显示效果产生不良影响，或者对前置摄像头的拍摄效果产生不良影响。如图5所示，图5为一种显示面板在与具有多个物理通孔的偏光片贴合之后的表面照片，其中箭头指向的位置具有通孔导致的印记，需要说明的是，图5仅仅用于表示显示面板在贴合之后会在表面产生印记这种现象，并不表示实际的显示组件。可见，在如图3和图4所示的结构中，虽然通过盲孔的设计提高了屏占比，但是又会由于盲孔的设计导致显示面板的不平整，因此，如何在提高屏占比的前提下提高显示面板的平整度是本申请实施例所要解决的问题，以下对本申请实施例进行说明。
如图6、图7和图8所示，本申请实施例提供了一种显示组件，包括：层叠设置的有机发光显示柔性面板1、偏光片2和盖板3，偏光片2位于有机发光显示柔性面板1和盖板3之间；偏光片2具有通孔20，偏光片2贴附于有机发光显示柔性面板1的 表面，偏光片2的杨氏模量小于1GPa；有机发光显示柔性面板1覆盖偏光片2的通孔20，有机发光显示柔性面板1具有位于通孔20位置处的透光区域10。
具体地，有机发光显示柔性面板1为柔性显示面板，也就是说，有机发光显示柔性面板1是基于柔性衬底基板制作的显示面板，有机发光显示柔性面板1中具有发光器件，发光器件具有阳极、阴极和有机发光层，有机发光层位于阳极和阴极之间，当其中阳极和阴极上施加电压时，有机发光层会发光，以实现显示功能，有机发光显示柔性面板1还包括用于驱动发光器件的电路和信号线，其中，在透光区域10，可以通过预先的布局，使有机发光显示柔性面板1中不透光的结构，例如发光器件、信号线和电路等设置于透光区域10之外，在透光区域10中仅保留透光材料的膜层，当然，在可能的实施方式中，透光区域10中也可以设置有较少的不透光结构，而在透光区域10之外，有机发光显示柔性面板1中会正常布局，即包括发光器件、信号线和电路等不透光的结构以实现显示功能，即有机发光显示柔性面板1中的显示区域可以包围透光区域10，在本申请实施例中，有机发光显示柔性面板1上不需要通过切割工艺来产生物理通孔，而是通过设置透光区域10的方式来实现透光功能，这样可以避免由于切割工艺而产生的无法显示区域，以提高屏占比。偏光片2用于阻挡环境光的出射，以提高显示效果，为了避免偏光片2对于前置摄像头等光学器件的不良影响，偏光片2上具有物理通孔20，且物理通孔20与透光区域10的位置相对应，即在偏光片2所在的平面上，有机发光显示柔性面板1中透光区域10的正投影与通孔20交叠。盖板3用于实现对有机发光显示柔性面板1和偏光片2的保护，盖板3例如为玻璃盖板。由于偏光片2的杨氏模量小于1GPa，在有机发光显示柔性面板1、偏光片2和盖板3之间的贴合工艺过程中，虽然偏光片2的通孔20内外对于有机发光显示柔性面板1所施加的应力具有差异，但是由于偏光片2的杨氏模量小于1GPa，因此不容易使有机发光显示柔性面板1产生与通孔20所对应的印记。对本申请实施例中贴合之后的显示组件的有机发光显示柔性面板1的表面进行测试，可以得到有机发光显示柔性面板1表面的峰值与谷值的差(Peak to Valley，PV)值＜1，PV值用于表征实际表面与理想平面的偏差量，即用于反映平整度，PV值越小则表面越平整，PV值＜1.3即可以满足有机发光显示柔性面板的要求。
本申请实施例中的显示组件，通过设置具有通孔的偏光片的杨氏模量小于1GPa，能够改善显示面板、偏光片和盖板之间贴合之后容易产生印记的问题，由于有机发光显示柔性面板上具有透光区域而非物理通孔，因此在提高屏占比的前提下提高了显示面板的平整度。
在一种可能的实施方式中，如图6、图7和图8所示，偏光片2的通孔20中填充有胶材，在显示组件的制作过程中，可以先将偏光片2贴附于有机发光显示柔性面板1的表面，然后将胶材填充至偏光片2的通孔20内，再将盖板3贴附于偏光片2远离有机发光显示柔性面板1的一侧，这样，在贴合盖板3的过程中，由于通孔20内填充有胶材，使得通孔20内外向有机发光显示柔性面板1所施加的应力更加均匀，从而进一步提高有机发光显示柔性面板1表面的平整度。
在一种可能的实施方式中，如图6、图7和图8所示，偏光片2的通孔中填充有液体光学胶，例如光学透明树酯(Optically Clear Resin，OCR)；显示组件还包括位 于偏光片2和盖板3之间的胶层4，胶层4为固体光学胶(Optically Clear Adhesive，OCA)，偏光片2通过固体光学胶粘接于盖板3。例如，在显示组件的制作过程中，可以先将偏光片2贴附于有机发光显示柔性面板1的表面，然后通过点胶机将OCR填充至偏光片2的通孔20内，然后在偏光片2远离有机发光显示柔性面板1一侧表面均匀涂布一层固体光学胶，再将盖板3贴附于偏光片2远离有机发光显示柔性面板1的一侧，使得盖板3通过固体光学胶粘接于偏光片2表面，这样，在贴合盖板3的过程中，由于通孔20内填充有胶材，使得通孔20内外向有机发光显示柔性面板1所施加的应力更加均匀，从而进一步提高有机发光显示柔性面板1表面的平整度。
在一种可能的实施方式中，如图6、图7和图8所示，显示组件还包括位于偏光片2和盖板3之间的胶层4，胶层4为液体光学胶，例如OCR，偏光片2通过液体光学胶粘接于盖板3，液体光学胶填充于偏光片2的通孔20中。例如，在显示组件的制作过程中，可以在偏光片2远离有机发光显示柔性面板1一侧表面均匀涂布一层液体光学胶，由于液体光学胶，可以在涂布的过程中被填充至通孔20内，再将盖板3贴附于偏光片2远离有机发光显示柔性面板1的一侧，使得盖板3通过液体光学胶粘接于偏光片2表面，这样，在贴合盖板3的过程中，由于通孔20内填充有胶材，使得通孔20内外向有机发光显示柔性面板1所施加的应力更加均匀，从而进一步提高有机发光显示柔性面板1表面的平整度。
如图7、图9和图10所示，本申请实施例还提供一种显示组件，包括：层叠设置的有机发光显示柔性面板1、间隔膜层5、偏光片2和盖板3，偏光片2位于有机发光显示柔性面板1和盖板3之间，间隔膜层5位于有机发光显示柔性面板1和偏光片2之间；偏光片2具有通孔20，偏光片2贴附于间隔膜层5的表面，间隔膜层5为透明膜层且覆盖偏光片2的通孔20；有机发光显示柔性面板1具有位于通孔20位置处的透光区域10。
具体地，如图7、图9和图10所示实施例结构中，有机发光显示柔性面板1、偏光片2和盖板3的具体结构可以与上述实施例相同。有机发光显示柔性面板1为柔性显示面板，也就是说，有机发光显示柔性面板1是基于柔性衬底基板制作的显示面板，有机发光显示柔性面板1中具有发光器件，发光器件具有阳极、阴极和有机发光层，有机发光层位于阳极和阴极之间，当其中阳极和阴极上施加电压时，有机发光层会发光，以实现显示功能，有机发光显示柔性面板1还包括用于驱动发光器件的电路和信号线，其中，在透光区域10，可以通过预先的布局，使有机发光显示柔性面板1中不透光的结构，例如发光器件、信号线和电路等设置于透光区域10之外，在透光区域10中仅保留透光材料的膜层，当然，在可能的实施方式中，透光区域10中也可以设置有较少的不透光结构，而在透光区域10之外，有机发光显示柔性面板1中会正常布局，即包括发光器件、信号线和电路等不透光的结构以实现显示功能，即有机发光显示柔性面板1中的显示区域可以包围透光区域10，在本申请实施例中，有机发光显示柔性面板1上不需要通过切割工艺来产生物理通孔，而是通过设置透光区域10的方式来实现透光功能，这样可以避免由于切割工艺而产生的无法显示区域，以提高屏占比。偏光片2用于阻挡环境光的出射，以提高显示效果，为了避免偏光片2对于前置摄像头等光学器件的不良影响，偏光片2上具有物理通孔20，且物理通孔20与透光区域 10的位置相对应，即在偏光片2所在的平面上，有机发光显示柔性面板1中透光区域10的正投影与通孔20交叠。盖板3用于实现对有机发光显示柔性面板1和偏光片2的保护，盖板3例如为玻璃盖板。图7、图9、图10所示实施例结构和如图6、图7、图8所示实施例结构的区别在于，在有机发光显示柔性面板1和偏光片2之间增加的间隔膜层5，且偏光片2无需设置特定的杨氏模量范围，通过间隔膜层5的应力阻隔作用，在有机发光显示柔性面板1、间隔膜层5、偏光片2和盖板3之间的贴合过程中，阻隔或降低了偏光片2对于有机发光显示柔性面板1所施加的应力作用，因此不容易使有机发光显示柔性面板1产生与通孔20所对应的印记。对如图7、图9和图10所示实施例中贴合之后的显示组件的有机发光显示柔性面板1的表面进行测试，可以得到有机发光显示柔性面板1表面的PV值＜1，可以满足有机发光显示柔性面板的要求。
本申请图7、图9和图10所示实施例中的显示组件，通过在偏光片和有机发光显示柔性面板之间设置间隔膜层，可以阻隔或降低偏光片和有机发光显示柔性面板之间的应力作用，能够改善显示面板、偏光片和盖板之间贴合之后容易产生印记的问题，由于有机发光显示柔性面板上具有透光区域而非物理通孔，因此在提高屏占比的前提下提高了显示面板的平整度。
在一种可能的实施方式中，如图7、图9和图10所示，间隔膜层5的厚度＞100μm，间隔膜层5的杨氏模量＜5GPa；或者，间隔膜层5的厚度＜50μm，间隔膜层5的杨氏模量＞70GPa。间隔膜层5的作用是阻隔或降低偏光片2和有机发光显示柔性面板1之间的应力作用，因此，如果间隔膜层5的厚度较大，则即便间隔膜层5的杨氏模量较小，也可以起到阻隔应力的作用，通过验证，可以设置间隔膜层5的厚度＞100μm，间隔膜层5的杨氏模量＜5GPa；而如果间隔膜层5的厚度较小，则需要设置间隔膜层5的杨氏模量较大，通过验证，可以设置间隔膜层5的厚度＜50μm，间隔膜层5的杨氏模量＞70GPa。
在一种可能的实施方式中，如图7、图9和图10所示，间隔膜层5的材料为塑料或玻璃；间隔膜层5的厚度为h，50μm≤h≤150μm。
另外需要说明的是，如图7、图9和图10所示实施例结构中，对于偏光片2和盖板3之间的贴合方式不作限定，例如可以设置位于偏光片2和盖板3之间的胶层4，使偏光片2和盖板3通过胶层4粘接，胶层4可以为任意类型，例如OCR或者OCA。
如图7、图11和图12所示，本申请实施例还提供一种显示组件，包括：层叠设置的有机发光显示柔性面板1、偏光片2和盖板3，偏光片2位于有机发光显示柔性面板1和盖板3之间；偏光片2具有偏振功能材料区域21和非偏振功能材料区域22；有机发光显示柔性面板1覆盖偏光片2的偏振功能材料区域21和非偏振功能材料区域22，有机发光显示柔性面板1具有位于非偏振功能材料区域22位置处的透光区域10。
具体地，如图7、图11和图12所示实施例结构中，有机发光显示柔性面板1和盖板3的具体结构可以与上述实施例相同，有机发光显示柔性面板1、偏光片2和盖板3的具体结构可以与上述实施例相同。有机发光显示柔性面板1为柔性显示面板，也就是说，有机发光显示柔性面板1是基于柔性衬底基板制作的显示面板，有机发光显示柔性面板1中具有发光器件，发光器件具有阳极、阴极和有机发光层，有机发光层位于阳极和阴极之间，当其中阳极和阴极上施加电压时，有机发光层会发光，以实 现显示功能，有机发光显示柔性面板1还包括用于驱动发光器件的电路和信号线，其中，在透光区域10，可以通过预先的布局，使有机发光显示柔性面板1中不透光的结构，例如发光器件、信号线和电路等设置于透光区域10之外，在透光区域10中仅保留透光材料的膜层，当然，在可能的实施方式中，透光区域10中也可以设置有较少的不透光结构，而在透光区域10之外，有机发光显示柔性面板1中会正常布局，即包括发光器件、信号线和电路等不透光的结构以实现显示功能，即有机发光显示柔性面板1中的显示区域可以包围透光区域10，在本申请实施例中，有机发光显示柔性面板1上不需要通过切割工艺来产生物理通孔，而是通过设置透光区域10的方式来实现透光功能，这样可以避免由于切割工艺而产生的无法显示区域，以提高屏占比。偏光片2用于阻挡环境光的出射，以提高显示效果，为了避免偏光片2对于前置摄像头等光学器件的不良影响，偏光片2上具有非偏振功能材料区域22，且非偏振功能材料区域22与透光区域10的位置相对应，即在偏光片2所在的平面上，有机发光显示柔性面板1中透光区域10的正投影与非偏振功能材料区域22交叠。偏光片2在非偏振功能材料区域22没有光线偏振的功能，即该区域任意光线都能够直接穿过非偏振功能材料且不会改变偏振方向，而偏光片2在偏振功能材料区域21具有相关的偏振功能，以阻挡环境光的出射。盖板3用于实现对有机发光显示柔性面板1和偏光片2的保护，盖板3例如为玻璃盖板。图7、图11、图12所示实施例结构和如图6、图7、图8所示实施例结构的区别在于，偏光片2通过设置非偏振功能材料区域22替代了物理通孔，这样，由于偏光片2上没有物理通孔，因此，即便直接将有机发光显示柔性面板1和偏光片2之间贴合，由于两者之间各位置处的应力作用差异较小，不会造成有机发光显示柔性面板1表面的印记。对如图7、图11和图12所示实施例中贴合之后的显示组件的有机发光显示柔性面板1的表面进行测试，可以得到有机发光显示柔性面板1表面的PV值＜0.5，可以满足有机发光显示柔性面板的要求。
本申请图7、图11、图12所示实施例中的显示组件，通过在偏光片上述设置与有机发光显示柔性面板中透光区域对应的非偏振功能材料区域，无需在偏光片上设置物理通孔，使得显示组件各部分的贴合过程中，有机发光显示柔性面板和偏光片之间各位置处的应力作用差异较小，从而改善了显示面板、偏光片和盖板之间贴合之后容易产生印记的问题，由于有机发光显示柔性面板上具有透光区域而非物理通孔，因此在提高屏占比的前提下提高了显示面板的平整度。
本申请实施例还提供了一种显示组件的制备方法，用于制备如图6、图7和图8所示实施例结构中的显示组件，显示组件的制备包括：提供有机发光显示柔性面板1、偏光片2和盖板3，将偏光片2贴附于有机发光显示柔性面板1的表面，在加热环境下将盖板3贴附于偏光片2远离有机发光显示柔性面板1的一侧。在真空环境下进行盖板3贴合的过程中加热，可以进一步改善显示面板、偏光片和盖板之间贴合之后容易产生印记的问题。
如图13所示，本申请实施例还提供了一种显示装置，包括：上述任意实施例中的显示组件100：光学器件200，光学器件200位于显示组件100中有机发光显示柔性面板1远离偏光片的一侧，光学器件200位于有机发光显示柔性面板1的透光区域10所在位置，即在有机发光显示柔性面板1所在的平面上，光学器件200的正投影与透 光区域10交叠，以使光学器件200可以通过透光区域10获取来自于显示组件100另外一侧的光。例如，光学器件200可以为摄像头，该摄像头可以通过透光区域10拍摄位于显示组件100另外一侧的照片。其中，显示组件的具体结构和原理可以与上述任意实施例中的记载相同，在此不再赘述。显示装置可以是例如触摸显示屏、手机、平板计算机、笔记本电脑或电视机等任何具有显示功能的电子设备。
