显示屏及电子设备
交叉引用
本发明要求在2020年03月24日提交中国专利局、申请号为202010215947.X、发明名称为“显示屏及电子设备”的中国专利申请的优先权，该申请的全部内容通过引用结合在本发明中。
技术领域
本发明实施例涉及显示技术领域，尤其涉及一种显示屏及电子设备。
背景技术
随着用户对电子设备的使用需求不断提升，电子设备的屏幕尺寸不断扩大，同时屏幕尺寸的增加通常会导致电子设备的整体尺寸变大，随之带来的就是不便于携带的问题。因此，目前对于电子设备的结构设计来说，较大的屏幕尺寸与便携性已经成为比较突出的矛盾。
为了同时满足用户对于较大的屏幕尺寸与便携性的需求，可折叠的电子设备应运而生。此种电子设备具有折叠状态和展开状态，电子设备处于展开状态时，显示屏展平，进而可以获得更大的显示区域；电子设备处于折叠状态时，显示屏弯折，此时电子设备的整体尺寸减小，从而便于携带。
上述电子设备的显示屏可以包括柔性显示屏本体、连接胶和保护层，保护层可以通过连接胶与柔性显示屏本体相连，从而保护柔性显示屏本体。但是，此种保护层的强度偏弱，其对柔性显示屏本体的保护作用比较有限，导致显示屏容易损坏。
发明内容
本发明实施例公开一种显示屏及电子设备，以解决显示屏容易损坏的问题。
为了解决上述技术问题，本发明是这样实现的：第一方面，本发明实施例提供了一种显示屏，包括柔性显示屏本体、连接胶和保护层，所述柔性显示屏本体通过所述连接胶与所述保护层相连，且所述保护层覆盖所述连接胶；
所述柔性显示屏本体包括第一区域、第二区域和第三区域，所述第三区域位于所述第一区域和所述第二区域之间，所述保护层对应所述第三区域设置有至少两个凹陷部，各所述凹陷部沿所述柔性显示屏本体的弯折轴线的延伸方向间隔排布。
第二方面，本发明实施例提供了一种电子设备，包括上述显示屏，所述显示屏还包括电路板，所述电路板与所述柔性显示屏本体相连。
在本发明实施例中，显示屏的保护层设有凹陷部，该凹陷部使得保护层对应于柔性显示屏本体的弯折区域的部分具有更好的柔性，从而保证显示屏的弯折性能，因此，保护层的结构强度更不容易受到显示屏的弯折性能的限制，使得保护层可以更有力地保护柔性显示屏本体，使得显示屏不容易损坏。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1～图3所示，本发明实施例公开一种显示屏，该显示屏为柔性结构，其可以进行弯折，从而可以通过展平操作获得更大的显示面积，同时通过弯折操作获得更小的收纳尺寸，以此满足用户对于更大的屏幕尺寸以及便携性的需求。可选地，该显示屏可以应用于可折叠电子设备中，当电子设备处于展开状态时，显示屏展平(即图2所示状态)；当电子设备处于折叠状态时，显示屏被弯折(即图1所示状态)。
本发明实施例中，显示屏可以包括柔性显示屏本体100、连接胶200和保护层300。柔性显示屏本体100可以作为显示屏的主体结构，该柔性显示屏本体100可以通过连接胶200与保护层300相连，使得保护层300与柔性显示屏本体100粘接在一起，且保护层300可以覆盖连接胶200，从而保护柔性显示屏本体100。可选地，保护层300可以仅设置一层，也可以设置多层，本发明实施例对此不做限制。另外，这里的连接胶200可以是光学胶，该光学胶具有比较优异的透光性，使得连接胶200既可以实现柔性显示屏本体100与保护层300之间的连接，又可以保证显示屏的透光性。
另外，上述显示屏还可以包括电路板400，该电路板400与柔性显示屏本体100相连，从而可以实现柔性显示屏本体100的驱动，以实现显示屏的显示功能。可选地，这里的电路板400可以是柔性电路板。
根据上文内容可知，柔性显示屏本体100可以弯折，其具体可包括第一区域、第二区域和第三区域，第三区域位于第一区域和第二区域之间。可选地，这里的第一区域和第二区域均可以采用平面结构，第三区域可以是柔性显示屏本体100的弯折部分，其可以弯折为弧形结构。保护层300可以对应 第三区域设置有至少两个凹陷部310，也就是说，保护层300对应于第三区域的部分设置有凹陷部310。各凹陷部310可以间隔排布，此时，保护层300中处于相邻的凹陷部310之间的部分为实体部分，且该部分与保护层300对应于第一区域和第二区域的部分相连，因此其结构强度可以满足保护柔性显示屏本体100的需求，同时可以通过凹陷部310使得保护层300对应于第三区域的部分的柔性更好。具体地，各凹陷部310可以沿柔性显示屏本体100的弯折轴线的延伸方向间隔排布，当显示屏进行弯折时，保护层300中处于相邻的凹陷部310之间的部分将会同步弯折。
可选地，凹陷部310可以通过数控加工的方式形成，例如可以采用铣削等工艺形成该凹陷部310，另外，凹陷部310的形状及尺寸均可以灵活选择，本发明实施例对此不做限制。
本发明实施例公开的上述显示屏中，保护层300设有凹陷部310，该凹陷部310使得保护层300对应于柔性显示屏本体100的弯折区域(即第三区域)的部分具有更好的柔性，从而保证显示屏的弯折性能，因此，保护层300的结构强度更不容易受到显示屏的弯折性能的限制，使得保护层300可以更有力地保护柔性显示屏本体100，使得显示屏不容易损坏。
可选地，当显示屏展平时，在垂直于柔性显示屏本体100的方向上，各凹陷部310的投影均可以位于第三区域的投影内，同时，保护层300设置凹陷部310的部分的投影可以与第三区域的投影相重合，使得各凹陷部310可以尽量覆盖第三区域，从而使得显示屏更容易弯折。进一步地，在显示屏处于展开状态的情况下，凹陷部310沿垂直于柔性显示屏本体100的方向的正投影轮廓线与第三区域沿垂直于柔性显示屏本体100的方向的正投影轮廓线部分重合。将第一区域向第二区域延伸的方向定义为第一方向，此时，凹陷部310在第一方向上的尺寸(具体可以是凹陷部310的长度)基本等于第三区域在第一方向上的尺寸，因此凹陷部310可以更好地覆盖第三区域，从而使得显示屏更容易弯折，同时也不会过渡削弱保护层300的结构强度。
设置凹陷部310以后，保护层300的结构强度会有所下降，因此为了在保证显示屏的弯折性能的同时，尽量提升保护层300的结构强度，从而更好地保护柔性显示屏本体100，显示屏还可以包括填充胶500，该填充胶500设置于凹陷部310内。这里的填充胶500可以填充凹陷部310的内部空间，其与保护层300粘接，从而使得保护层300中设置凹陷部310的部分的结构强度更高。可选地，填充胶500的顶面可以与凹陷部310开口侧平齐，使得填充胶500刚好填充满凹陷部310，同时不会溢出。
可选地，上述填充胶500可以通过灌胶工艺形成，当然，也可以通过其他方式形成填充胶500，本发明实施例对此不做限制。另外，填充胶500的具体种类可以灵活选择，其可以是具有柔性且不影响显示屏正常显示的胶，本发明实施例对此不做限制。例如，该填充胶500可以是光学胶，该光学胶具有比较优异的透光性，使得填充胶500既可以实现填充作用，又可以保证显示屏的透光性。进一步地，填充胶500的折射率可以与保护层300的折射率相等，从而使得显示屏的外观一致性更好。
可选的实施例中，保护层300为柔性玻璃保护层。即，保护层300的材料可以是柔性玻璃，此种材料具有较好的柔性，同时具有更高的结构强度和抗冲击能力，从而更好地保护柔性显示屏本体100。进一步地，保护层300的材料可以是具有柔性的强化玻璃，以使保护层300的保护效果更佳，例如，可以通过化学强化的方式使得保护层300的强度更高。另外，可以进一步对保护层300设置凹陷部310的部分进行抛光处理，使得凹陷部310的表面的裂纹更少，从而进一步提升保护层300的结构强度。当凹陷部310内设有填充胶500时，这里的抛光处理可以使填充胶500更紧密地与保护层300粘接，从而进一步改善保护层300的结构强度。
可选地，上述保护层300可以包括依次相连的第一保护部320、第三保护部340和第二保护部330，第一保护部320对应第一区域设置，第二保护部330对应第二区域设置，第三保护部340对应第三区域设置，第三保护部 340设有前文所述的凹陷部310。采用此种结构后，柔性显示屏本体100的第一区域、第二区域和第三区域均可以得到比较理想的保护，从而使得显示屏更不容易损坏。同时，第一保护部320、第二保护部330和第三保护部340连接为一个整体，使得保护层300的结构强度更高，其所带来的保护效果更优。
第一保护部320、第二保护部330和第三保护部340可以采用分体式结构，即三者可以分别成型后再通过粘接等方式连接成一个整体，但是为了进一步增大保护层300的结构强度，可以采用一体成型的方式制造保护层300，使得第一保护部320、第三保护部340和第二保护部330为一体式结构，即三者相连后所形成的结构为一体式结构。
可选地，凹陷部310可以是通孔，此时，凹陷部310可以贯通第三保护部340，凹陷部310的一端直接延伸至连接胶200处。采用此种结构后，第三保护部340的实体部分更少，从而使得第三保护部340的柔性更佳，更有利于显示屏进行弯折。同时，当显示屏还包括填充胶500时，该填充胶500可以延伸至连接胶200处，并且可以与连接胶200直接粘接，甚至融为一体，两者的结合强度较高，使得整个显示屏的结构强度更高。
上述第一保护部320、第二保护部330和第三保护部340的厚度均可以灵活设置，为了简化保护层300的成型工艺，第一保护部320、第二保护部330和第三保护部340的厚度可以相等。一种可选的实施例中，第一保护部320的厚度可以为50um～500um；和/或，第二保护部330的厚度为50um～500um；和/或，第三保护部340的厚度为50um～500um。当第一保护部320、第二保护部330和第三保护部340的厚度采用这里所述的数值范围时，保护层300的结构强度、抗冲击性能较好，且其具有更理想的弯折性能。当然，第一保护部320、第二保护部330和第三保护部340的厚度还可以采用其他数值，本发明实施例对此不做限制。
基于上述任意实施例所述的显示屏，本发明实施例还公开一种电子设备， 该电子设备包括上述任意实施例所述的显示屏，该显示屏可以包括前文所述的柔性显示屏本体100、连接胶200和保护层300，还可以包括电路板400，该电路板400与柔性显示屏本体100相连。
本发明实施例公开的电子设备可以是智能手机、平板电脑、电子书阅读器、可穿戴设备(例如智能手表)、电子游戏机等设备，本发明实施例不限制电子设备的具体种类。
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。
