Description

一种显示面板及显示装置 技术领域
本发明涉及显示面板技术领域，特别涉及一种显示面板及显示装置。
 背景技术
手机等移动终端的技术发展日新月异。手机屏幕尺寸大小、屏占比、分辨率等指标影响着用户体验，其中，屏占比直接影响着手机美观及使用感受，也是各个商家提升的目标。
为了提高屏占比，目前现有技术中以刘海屏、水滴屏为代表，逐渐占据市场的主流，虽然一定程度的提高了屏占比，但需要使用异形切割技术，不仅影响了美观，而且依然无法避开前置摄像头。另一技术是升降屏，升降屏虽然不用做异形切割，且可以实现正面显示区扩大，但是其需要在外部添加升降系统，手机抗摔等机械性能减弱。
目前市场上有出现更高的屏占比的声音，虽然还没有真正量产品上市，但各家已经在开发。其开发思路是在屏幕上挖孔设计，放置前置摄像头，将摄像机模组隐藏在面板中，OLED面板上有多层金属走线，且随着PPI的提高，金属走线密集程度提高，外界光线无法大量透过金属走线到达摄像镜头。
因此，确有必要来开发一种新型的显示面板，以克服现有技术的缺陷。
 技术问题
本发明的一个目的是提供一种显示面板，其能够解决现有技术中为了提高屏占比导致的手机不美观、抗摔机械性能减弱以及面板层叠的透光率小等问题。
 技术解决方案
为实现上述目的，本发明提供一种显示面板，包括主显示面板和副显示面板，其中所述主显示面板包括显示区和功能区；所述副显示面板位于所述主显示面板下并能在第一位置和第二位置间转换位置；其中，当所述副显示面板处于所述第一位置时，所述副显示面板位于所述主显示面板的功能区下方，同时所述副显示面板对应设置在所述主显示面板功能区的位置，当所述副显示面板在所述第二位置时，所述副显示面板处于所述主显示面板的显示区的下方。

进一步的，在其他实施方式中，其中所述第二基板层的厚度为所述第一基板层厚度的20%～80%，优选所述第二基板层的厚度为所述第一基板层厚度的40%。其中在其他实施方式中，所述第二基板层的厚度可随需要而定，并无限定，只要能保证所述第二基板层的厚度小于所述第一基板层的厚度即可。
本发明的另一目的是提供一种显示装置，其包括本体，所述本体上设置本发明涉及的所述显示面板，其中所述本体上还设置有一驱动件，所述驱动件与所述副显示面板连接，并能带动所述副显示面板在所述第一位置和所述第二位置之间转换位置。
进一步的，在其他实施方式中，其中所述驱动件通过收缩的方式带动所述副显示面板在所述第一位置和所述第二位置之间转换位置。
进一步的，在其他实施方式中，其中所述本体上还设置有主板，所述主板连接所述主显示面板和所述副显示面板，通过控制所述主板能够调控所述主显示面板和所述副显示面板两块屏幕的显示效果。

 有益效果
相对于现有技术，本发明的有益效果在于提供一种显示面板及显示装置，显示面板包括主显示面板和副显示面板，将摄像头模组隐藏在屏幕下方，通过驱动件带动副显示面板移动，当摄像头模组关闭时，驱动件带动副显示面板移动至功能区，使其与主显示面板形成一体；当摄像头模组打开时，驱动件带动副显示面板离开功能区，此时没有副显示面板中的金属膜层的遮挡，外界光线可以顺利进入摄像头模组的镜头，从而提高透过率，优化镜头使用效果，这样的设置方式一方面提高了屏幕的屏占比，另一方面没有外部机械结构，进一步提高手机抗摔性能。

实施例1
请参阅图1，图1所示为本实施例提供的显示面板的俯视示意图，本发明提供一种显示面板，其包括主显示面板1、副显示面板2和摄像头模组3，副显示面板2设置于主显示面板1的下方并能在一第一位置和第二位置间转换位置，摄像头模块3设置于副显示面板2的下方。
请参阅图2，本发明还提供一种显示装置，其包括本体，本体上设置本发明涉及的所述显示面板，主显示面板1包括有功能区4和显示区5，其中本体上还设置有驱动件6，驱动件6与副显示面板2连接，并能通过收缩的方式带动副显示面板2在第一位置和第二位置之间转换位置。
图2所示为本实施例提供的当副显示面板在第一位置时显示装置的剖视示意图，当副显示面板2在第一位置时，其处于主显示面板1的功能区下方及摄像头模块3的上方，同时副显示面板2能够填补主显示面板1功能区4的位置，并与主显示面板1的显示区4结合在一起实现主显示面板1表面的完整显示；图3为本实施例提供的副显示面板在第二位置时显示装置的剖视示意图，当副显示面板2在第二位置时，其处于主显示面板1的显示区5的下方，以使摄像头模块3能够接收外界光线。
当摄像头模组3关闭时，驱动件6带动副显示面板2位于第一位置，此时副显示面板2能够填补主显示面板1功能区4的位置，并与主显示面板1的显示区5结合在一起实现主显示面板1表面的完整显示；当摄像头模组3打开时，驱动件6带动副显示面板2位于第二位置，此时功能区4没有副显示面板2中的金属膜层的遮挡，外界光线可以顺利进入摄像头模组3的镜头，从而提高透过率，优化镜头使用效果。
在显示区5，主显示面板1包括依次设置的第一基板层11、薄膜晶体管层12、发光层13、封装层14和偏光片15，在功能区4，主显示面板1包括依次设置的第一基板层11和封装层14。
第一基板层11可为聚酰亚胺（PI），聚碳酸酯（PC），聚对苯二甲酸乙二醇酯（PET），聚萘二甲酸乙二醇酯（PEN）等，在本实施例中优选为PI膜层，即聚酰亚胺薄膜，作为显示面板的基底；聚酰亚胺薄膜是世界上性能最好的薄膜类绝缘材料，具有较强的拉伸强度，由均苯四甲酸二酐和二氨基二苯醚在强极性溶剂中经缩聚并流延成膜再经亚胺化而成。
薄膜晶体管层12包括依次设置的缓冲层、绝缘层、半导体层，第一栅极绝缘层、第一金属层、第二栅极绝缘层、第二金属层、层间绝缘层和第三金属层。其中缓冲层和绝缘层可以起到阻挡第一基板层11中部分金属离子在后续高温制程中引入杂质而对产品产生影响；

发光层13包括像素定义层和RGB层，封装层14包括依次设置的第一无机封装层、第一有机封装层和第二无机封装层，由于G、RGB发光材料对水汽、氧气非常敏感，因此需要对其进行封装保护，保护区域扩大至功能区5，形成一体效果，保证封装效果。因为无机封装材料和有机封装材料均为透明材料，因此，对于屏下摄像区域4透过率几乎没有影响。
显示装置的本体上还设置有主板，主板连接主显示面板1和副显示面板2，通过控制主板能够调控主显示面板1和副显示面板2两块屏幕的显示效果。
副显示面板2的结构和主显示面板1的结构类似，在此不再赘述。
实施例2

请参阅图6，图6为本实施例提供的显示面板的俯视示意图，本实施例中的显示面板结构与实施例1大致相同，其相同的结构可参照上述方式，此处不再赘述，其主要不同之处在于，主显示面板表面定义有两个功能区，显示区将这两个功能区分隔设置，两个个功能区下对应设置有两个副显示面板2和两个摄像头模组3，两个摄像头模组3并列设置，功能区位置也不限于屏幕的左上角。
在其他实施方式中，功能区的设置数量和设置位置可随需要而定，并无限定。副显示面板和摄像头模组的设置数量也可随需要而定，并无限定。
本发明的有益效果在于提供一种显示面板及显示装置，将摄像头模组隐藏在屏幕下方，通过驱动件带动副显示面板移动，当摄像头模组关闭时，驱动件带动副显示面板移动至功能区，使其与主显示面板形成一体；当摄像头模组打开时，驱动件带动副显示面板离开功能区，此时没有副显示面板中的金属膜层的遮挡，外界光线可以顺利进入摄像头模组的镜头，从而提高透过率，优化镜头使用效果，这样的设置方式一方面提高了屏幕的屏占比，另一方面没有外部机械结构，进一步提高手机抗摔性能。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
