本技术领域技术人员可以理解，除非另外定义，这里使用的所有术语(包括技术术语和科学术语)，具有与本申请所属领域中的普通技术人员的一般理解相同的意义。还应该理解的是，诸如通用字典中定义的那些术语，应该被理解为具有与相关技术的上下文中的意义一致的意义，并且除非像这里一样被特定定义，否则不会用理想化或过于正式的含义来解释。
为了解决相关技术中的显示基板在剧烈的震动环境下，可能出现的由破裂引起的各种不良问题，本公开提供一种新的显示基板的设计方式。
在第一方面中，图1和图2示出了本公开示例性实施例提供的显示基板。如图1和图2所示，该显示基板包括：衬底基板1，设置在衬底基板1上的发光器件2，以及设置在衬底基板1上、用于封装发光器件 2的封装层3。具体地，发光器件2包括：设置在衬底基板1上的发光层20和设置在该发光层20上的阴极21；封装层3包括：依次设置在阴极21上的第一无机封装层30、有机封装层31和第二无机封装层32。当然，需要说明的是，实际设计时，发光器件2还包括阳极(图中未示出)，发光器件2的具体设置方式可以与相关技术相同，这里不再赘述。另外，需要说明的是，图1中仅示出了封装层3包括两层无机封装层和一层有机封装层，实际设计时，封装层3可以包括更多层的无机封装层和更多层的有机封装层，无机封装层和有机封装层按照相互交替的方式叠层设置，封装层3的具体位置以及材料选择可以与相关技术相同，这里不再赘述。
如图1和图2所示，本公开示例性实施例提供的显示基板还包括：设置在衬底基板1上的防震层4。其中，防震层4在衬底基板1上的正投影区域与发光器件2在衬底基板1上的正投影区域无重叠区域。防震层4在衬底基板1上的正投影区域与封装层3在衬底基板1上的正投影区域存在重叠区域，且该重叠区域的面积小于防震层4在衬底基板1上的正投影区域的面积，即本公开实施例中，至少一部分防震层4被第一无机封装层30覆盖，另一部分防震层4未被第一无机封装层30覆盖。本公开实施例中设置的防震层4能够防止显示基板在使用过程中由于环境震动造成的应力破坏，主要起到一种缓冲作用。
由于本公开实施例提供的显示基板包括防震层4，防震层4在衬底基板1上的正投影区域与发光器件2在衬底基板1上的正投影区域无重叠区域；防震层4在衬底基板1上的正投影区域与封装层3在衬底基板1上的正投影区域存在重叠区域，且该重叠区域的面积小于防震层4在衬底基板1上的正投影区域的面积。防震层4的这种设置方式可以增强显示基板的整体防震性能，能够有效的避免显示基板在剧烈的震动环境下，出现的由震动导致的破裂而引起的各种不良的发生。另外，当该显示基板应用在车载显示屏时，能够应对车辆行驶中遇到的震动环境，从而确保显示屏在剧烈震动行驶条件下的正常工作，以保证驾驶人员的安 全。
在一些实施例中，为了使得本公开实施例提供的显示基板的结构更加多样性，以及考虑防震层4的位置和尺寸对防震性能的影响，本公开给出了两种具体的示例性实施方式。在一个示例性实施例中，如图1所示，防震层4连续设置，也就是说，防震层4具有连续不间断地形成在衬底基板1上的整体式结构。在另一个示例性实施例中，如图2所示，防震层4间断设置，也就是说，防震层4可以采用分体式结构，即具有形成在衬底基板1上的两个或多个彼此间断的部分。
例如，如图2所示，当防震层4间断设置时，封装层3的边缘位置在衬底基板1上的正投影区域位于两个或多个彼此间断的部分之间的间断位置在衬底基板1上的正投影区域之中，也就是说，间断位置与封装层3的边缘位置对应。实际设计时，防震层4还可以设置多个间断位置，具体的间断位置可以根据实际需要以及显示基板边框区域的尺寸设计；当然，间断位置设置的较多时，相对需要的边框区域的尺寸较大。
需要说明的是，图1所示的防震层4的设置方式不仅增加了防震层4的尺寸，增强防震能力，还在工艺和设计上，可以增大设计可控量和增大设备工艺的调整量，实现工艺和设计简化等优势。图2所示的防震层4的设置方式在结构上可有效减弱震动带来的冲击力，但在设计和工艺上有一定难度。
如图1和图2所示，本公开示例性实施例提供的显示基板还可以包括：设置在衬底基板1上的防裂层5和多个阻水氧层6。阻水氧层6设置在发光器件2和防震层4之间的区域，且阻水氧层6在衬底基板1上的正投影区域位于封装层3在衬底基板1上的正投影区域之中。防裂层5远离防震层4设置，且防裂层5在衬底基板1上的正投影区域与封装层3在衬底基板1上的正投影区域无重叠区域。由于本公开实施例的显示基板在设置防震层4的同时，还设置了防裂层5和阻水氧层6，使得显示基板可以同时防震、防裂和防水，进一步增强显示基板的安全性能，增加使用寿命，提升市场竞争力。
具体地，阻水氧层6主要用于阻止水氧对显示基板的显示区的侵蚀，阻水氧层6与防震层4之间间隔有一定距离，以使得阻水氧层6能够很好的满足阻水氧的需求；本公开实施例并不限定阻水氧层6的具体位置以及个数，阻水氧层6可以根据显示基板边框区域的尺寸设计；另外，图1和图2的阻水氧层6的上方还可以设置有机层，该有机层可以用来填补断层差，本公开实施例中阻水氧层6的具体设置方式与相关技术类似，这里不再赘述。
具体地，防裂层5位于显示基板1的边缘，且距离显示基板1的最外边需要预留一定的用于激光切割的灼烧区，防裂层5用于防止由于激光切割导致显示区的破裂。具体实施时，如图2所示，防裂层5可以进一步包括第一部分51和第二部分52。防裂层5包括的第一部分51选用有机材料制作，防裂层5包括的第二部分52选用无机材料制作，本公开实施例中防裂层5的具体设置方式与相关技术类似，这里不再赘述。
在一些实施例中，本公开实施例中防震层4的体积大于阻水氧层6的体积。这种设置方式能够进一步增强显示基板的防震效果。
在一些实施例中，阻水氧层6、防震层4和防裂层5的材料包括有机材料。采用有机材料能够制作出厚度较厚的阻水氧层6、防震层4和防裂层5，且制作成本较低，进而能够提升市场竞争力。
另外，由于阻水氧层6、防震层4和防裂层5的材料包括有机材料，在涂覆一层有机膜层后，该有机膜层可同时制作出阻水氧层6、防震层4和防裂层5，只需对一块掩膜板同时设计阻水氧层6、防震层4和防裂层5的图案即可，不仅不增加额外工序，也不需要额外增加掩膜板成本。
具体而言，以防裂层5包括的第二部分52已经制作完成为前提，如图3所示，显示基板中的阻水氧层6、防震层4和防裂层5的制作方法包括：
S101：在制作有发光器件2以及防裂层5的第二部分52的衬底基板上涂覆有机材料。
S102：采用同时具有阻水氧层6、防震层4和防裂层5的图案的掩膜板对有机材料进行曝光。
S103：曝光后的该层有机材料进行显影、固化处理，以形成阻水氧层6、防震层4和防裂层5的第一部分51。
在第二方面中，本公开实施例提供了一种显示模组，该显示模组包括如上文描述的第一方面中任一实施例所述的显示基板。由于第二方面中所述的显示模组包括了第一方面中任一实施例所述的显示基板，使得显示模组具有与第一方面中任一实施例所述的显示基板相同的有益效果。因此，在此不再重复赘述第二方面中的显示模组的有益效果。
在一个示例性实施例中，如图4所示，本公开实施例的显示模组还包括：依次设置在显示基板43上的偏光片44和盖板45，设置在显示基板43远离偏光片44一侧的散热屏蔽层42，以及防震膜层41，防震膜层41设置在散热屏蔽层42远离显示基板43的一侧。偏光片44和盖板45的具体设置方式与相关技术类似，这里不再赘述。
如图4所示，在显示基板43的背部(即在显示基板43远离偏光片44的一侧)进行散热屏蔽层42的贴覆，起到对显示基板43屏幕的遮光、缓冲、散热、屏蔽等作用。并且，采用硅胶等具有良好导热性能的胶粘材料将防震膜层41贴覆于散热屏蔽层42上，从而提高显示模组整体的防震等级，以满足车载屏幕在剧烈震动环境下的工作稳定性。
需要说明的是，图4中的显示基板43可以为本公开实施例第一方面中任一实施例提供的设置有防震层4的显示基板，也可以为相关技术不设置防震层的普通的显示基板。当显示基板43为本公开实施例第一方面中任一实施例提供的设置有防震层4的显示基板时，在防震层4以及防震膜层41的共同作用下，能够实现一种具有高防震等级的显示模组。
在另一个示例性实施例中，如图5所示，本公开实施例的显示模组还包括依次设置在显示基板43上的偏光片44和盖板45，设置在显示 基板43远离偏光片44一侧的散热屏蔽层42，以及防震膜层41。防震膜层41与盖板45形成的结构包覆偏光片44、显示基板43和散热屏蔽层42。与图4所示示例性实施例中的显示模组的结构相比，图5所示示例性实施例中的显示模组包括的防震膜层41还能够减小左右震动带来的应力冲击，实现更高等级的防震能力。
具体地，防震膜层41可采用压花硅胶缓冲材料、泡沫以及其它具有防震缓冲功能的膜材。但是，对于本领域技术人员而言，根据实际需要，也可以使用其他合适的材料。
在第三方面中，本公开实施例公开了一种显示装置，包括如上文描述的第二方面中任一实施例所述的显示模组。由于第三方面的显示装置包括了第二方面中任一实施例所述的显示模组，使得显示装置具有与第二方面中任一实施例所述的显示模组相同的有益效果。因此，在此不再重复赘述第三方面的显示装置的有益效果。
应用本公开实施例所获得的有益效果至少包括：
1、由于本公开实施例的提供的显示基板包括防震层，防震层设置在封装层的边界位置，且防震层的一部分被封装层覆盖，另一部分未被封装层覆盖，防震层的这种设置方式可以增强显示基板的整体防震性能，能够有效的避免显示基板在剧烈的震动环境下，出现的由震动导致的破裂而引起的各种不良的发生。另外，当该显示基板应用在车载显示屏时，能够应对车辆行驶中遇到的震动环境，从而确保显示屏在剧烈震动行驶条件下的正常工作，以保证驾驶人员的安全。
2、由于本公开实施例的显示基板在设置防震层的同时，还设置了防裂层和阻水氧层，使得显示基板可以同时防震、防裂和防水，进一步增强显示基板的安全性能，增加使用寿命，提升市场竞争力。
3、由于本公开实施例的显示模组在显示基板的背部进行散热屏蔽层贴覆，起到对显示基板屏幕的遮光、缓冲、散热、屏蔽等作用。并且，采用硅胶等具有良好导热性能的胶粘材料将防震膜层贴覆于散热屏蔽 层上，从而提高显示模组整体的防震等级，以满足车载屏幕在剧烈震动环境下的工作稳定性。
以上所述仅是本公开的部分实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本公开原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本公开的保护范围。
