技术领域
本发明涉及显示技术领域，尤其涉及一种显示模组及电子设备。
背景技术
随着技术的进步及电子设备的发展，用户对于全面屏电子设备的需求逐渐增加，全面屏也逐渐成为一种发展趋势。
摄像头、传感器、补光灯等光学器件的安装位置是制约全面屏发展的主要因素。为了提升电子设备的屏占比，可以在电子设备的显示模组上设置透光区域，将摄像头等光学器件朝向透光区域设置，以实现光学器件所具备的功能。
具体地，显示模组可以包括叠置的第一基板和第二基板，为了不影响透光区域的透光率，第一基板和第二基板中位于该透光区域内的部分之间尽量不设置其他结构。在大气压强的作用下，第一基板和第二基板中位于该透光区域内的部分容易出现内凹变形，从而影响透光区域处的光学性能，致使光学器件的性能较差。
发明内容
本发明公开一种显示模组及电子设备，以解决光学器件的性能较差的问题。
为了解决上述问题，本发明的实施例公开了一种显示模组，显示模组具有透光区域、外沿区域和显示区域，外沿区域位于透光区域与显示区域之间，
显示模组包括第一基板、第二基板、第一支撑部和第二支撑部，第一基板和第二基板叠置，第一基板设有薄膜晶体管，第二基板设有彩色滤光膜，第一支撑部和第二支撑部均设置于第一基板和第二基板之间，第一支撑部的高度大于第二支撑部的高度，第一支撑部位于显示区域内，第二支撑部位于外沿区域内，
其中，高度所在的方向为垂直于第一基板的方向。
本发明的实施例还公开了一种电子设备，包括上述显示模组和光学器件，光学器件和第二基板分别位于第一基板的两侧，透光区域与光学器件相对设置。
本发明采用的技术方案能够达到以下有益效果：
本发明公开的显示模组设有第二支撑部，该第二支撑部设置于显示模组的外沿区域中，该外沿区域邻近显示模组的透光区域，因此第二支撑部可以向第一基板和第二基板施加支撑力，当第一基板和第二基板出现内凹变形时，在第二支撑部的作用下，发生内凹变形的区域将自透光区域适当外扩，使得第一基板和第二基板的变形量趋于平缓，从而减小第一基板和第二基板的变形量，使得光学器件的性能有所提升。

如图1所示，本发明实施例公开一种显示模组，该显示模组可以应用于具有光学器件的电子设备中。本发明实施例所公开的显示模组具有透光区域A、外沿区域B和显示区域，外沿区域B位于透光区域A与显示区域之间。其中：透光区域A与光学器件相对设置，使得外部环境中的光线可以通过该透光区域A进入光学器件内，或者光学器件发出的光线可以通过该透光区域A进入外部环境中；外沿区域B紧邻该透光区域A设置，该外沿区域B具体可以用于设置走线结构。
具体地，上述显示模组可以包括第一基板110、第二基板120、第一支撑部130和第二支撑部140。第一基板110和第二基板120叠置，可选地，第一基板110和第二基板120均可以采用玻璃板，该玻璃板具有较高的透光率。第一基板110设有薄膜晶体管，该薄膜晶体管可以实现显示模组的驱动，第二基板120设有彩色滤光膜，该彩色滤光膜可以实现滤光，从而发出所需颜色的光。
第一支撑部130和第二支撑部140均设置于第一基板110和第二基板120之间，且两者均位于透光区域A之外，因此这里的第一支撑部130和第二支撑部140均不会对透光区域A的透光率产生影响，使得透光区域A具有较高的透光率，光学器件的性能更高。其中，第一支撑部130的高度大于第二支撑部140的高度，第一支撑部130位于显示区域内，第二支撑部140位于外沿区域B内。这里所述的高度所在的方向为垂直于第一基板110的方向。可选地，第 一支撑部130的数量可以设置为多个，该第一支撑部130的一端可以与第二基板120相连，另一端可以与第一基板110接触，从而向第一基板110和第二基板120施加较大的作用力。第二支撑部140的高度为预设高度，该预设高度可以根据第一支撑部130的高度等因素灵活设计，第二支撑部140的数量可以设置为一个，该第二支撑部140的一端可以与第二基板120相连，另一端与第一基板110之间具有间隙，当第一基板110和第二基板120出现内凹变形时，第二支撑部140可以与第一基板110接触，从而向第一基板110和第二基板120施加支撑力。
上述外沿区域B邻近透光区域A设置，第二支撑部140可以向第一基板110和第二基板120施加支撑力，当第一基板110和第二基板120出现内凹变形时，在第二支撑部140的作用下，发生内凹变形的区域将自透光区域A适当外扩，使得第一基板110和第二基板120的变形量趋于平缓，从而减小第一基板110和第二基板120在垂直于第一基板110的方向上的变形量，从而改善透光区域A处的光学性能，使得光学器件的性能有所提升。
可选地，上述外沿区域B可以环绕透光区域A。这样设置一方面可以提升显示模组的外观质感，另一方面可以形成较大的空间以便于设置第二支撑部140，在设计显示模组的结构时，可以根据实际情况灵活调整第二支撑部140的设置位置，从而简化显示模组的设计，同时达到更优的支撑效果。
一种可选的实施例中，第二支撑部140包括支撑柱141，该支撑柱141的高度为前文所述的预设高度。也就是说，此实施例中，第二支撑部140仅包括支撑柱141。第一基板110朝向第二支撑部140一侧以及第二基板120朝向第二支撑部140的一侧可能设置有其他膜层结构，当第二支撑部140仅包括支撑柱141时，这些膜层结构中对应第二支撑部140的部分可以去除，使得第二支撑部140可以更好地向第一基板110和第二基板120施加支撑力。
如图2所示，在另一实施例中，第二支撑部140可以包括支撑柱141和支撑膜层142。第一基板110和第二基板120中，一者设有该支撑柱141，另一 者设有该支撑膜层142，该支撑柱141和支撑膜层142沿垂直于第一基板110的方向排布，且支撑柱141的高度和支撑膜层142的高度之和等于前文所述的预设高度。此时，支撑柱141和支撑膜层142共同起支撑作用，从而减小透光区域A处发生的变形。该支撑膜层142可以是第一基板110或第二基板120上已经成型的膜层结构，因此如此设置后，不需要专门去除该膜层结构中对应于第二支撑部140的部分，从而简化显示模组的成型工艺。
上述支撑膜层142的材料可以不做具体限制，只要能够起到支撑效果即可。可选地，支撑膜层142可以为金属层、无机层或者有机层。
为了强化第二支撑部140的支撑效果，可以将第二支撑部140的数量设置为多个，多个第二支撑部140间隔设置于外沿区域B内。随着第二支撑部140的数量不断增加，第二支撑部140的支撑面积随之增大，从而使得第二支撑部140向第一基板110和第二基板120施加的支撑力更大，第一基板110和第二基板120在垂直于第一基板110的方向上的变形量更小，从而进一步提升光学器件的性能。进一步地，当外沿区域B环绕透光区域A时，多个第二支撑部140可以沿着环绕透光区域A的方向间隔设置，使得第二支撑部140所产生的支撑力更均匀地分布在外沿区域B。
一种可选的实施例中，第二支撑部140靠近透光区域A的一侧边缘与透光区域A的边缘之间的间隙W为0～0.2mm。此时，第二支撑部140与透光区域A之间的距离较小，使得第二支撑部140可以更好地减缓第一基板110和第二基板120在透光区域A处的变形，以此更有效地减小第一基板110和第二基板120在垂直于第一基板110的方向上的变形量。可选地，为了强化该效果，第二支撑部140靠近透光区域A的一侧边缘与透光区域A的边缘之间的间隙W为0.1mm。
上文提到，显示区域内设有第一支撑部130，该第一支撑部130的高度基本等于第一基板110和第二基板120之间的距离，由于第一支撑部130向第一基板110和第二基板120施加的作用力较大，因此第一支撑部130的数量不宜 过多，但是这样又容易导致支撑效果不理想。为此，显示模组还包括第三支撑部，该第三支撑部同样设置于第一基板110和第二基板120之间，且其同样位于显示区域内，该第三支撑部的高度小于第一支撑部130的高度，因此当第一基板110和第二基板120未发生变形时，第三支撑部的一端与第一基板110或者第二基板120之间具有间隙，只有当第一基板110和第二基板120的变形量达到一定值时，第三支撑部才会产生支撑效果，从而改善支撑效果。
当设置上述第三支撑部时，第三支撑部的高度可以大于第二支撑部140的高度，也可以小于第二支撑部140的高度，当然也可以等于第二支撑部140的高度。为了简化显示模组的加工工艺，可以使第三支撑部的高度等于第二支撑部140的高度，此时即可通过同一工序同时加工第二支撑部140和第三支撑部。
另外，当第二支撑部140包括支撑柱141和支撑膜层142时，由于支撑膜层142的作用，支撑柱141的高度可能会等于第三支撑部的高度，因此可以同时成型第二支撑部140和第三支撑部，从而简化显示模组的加工工艺。当然，也可以额外设置支撑膜层142，使得支撑柱141的高度等于第三支撑部的高度，以便于同时成型第二支撑部140和第三支撑部。
可选地，本发明实施例公开的显示模组可以是液晶显示模组，此时该显示模组还可以包括液晶层150，该液晶层150设置于第一基板110和第二基板120之间。为了保证透光区域A的透光率，该液晶层150可以对应透光区域A开孔，从而使得液晶层150不会影响光线的传播。当然，该显示模组也可以是有机发光显示模组，本发明实施例对此不做限制。
本发明实施例还公开一种电子设备，其包括上述任一实施例所述的显示模组和光学器件，该光学器件和第二基板120分别位于第一基板110的两侧，透光区域A与光学器件相对设置。可选地，这里的光学器件可以包括指纹模组、摄像头、传感器和补光灯中的至少一者。
本发明实施例所公开的电子设备可以为智能手机、平板电脑、电子书阅读器或可穿戴设备。当然，该电子设备也可以是其他设备，本发明实施例对此不 做限制。
本发明上文实施例中重点描述的是各个实施例之间的不同，各个实施例之间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
以上所述仅为本发明的实施例而已，并不用于限制本发明。对于本领域技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
