本实施例中，所述柔性屏板3321的宽度小于所述保护层334的宽度而相对于所述保护层334内缩，有利于所述保护层334更好地保护所述屏体332。

请参阅图9，图9是本申请第七实施例中的电子装置的正面结构示意图。本申请电子装置的第七实施例的结构与第一实施例的结构相似，不同之处在于：第七实施例中，所述保护层334与所述支撑片31之间在可折弯区域3320内设置有相互间隔的若干胶水50，每一胶水50呈条形状，每一条形状的胶水 50沿所述支撑片31的外侧的长度方向延伸，即，每一条形状的胶水50沿所述屏体332的外侧的长度方向延伸。
本实施例中，若干条形状的所述胶水50沿所述屏体332的宽度方向间隔排列，若干条形状的胶水50固化后均具有弹性，这些固化后的胶水50能使支撑片31与保护层334连接更牢固。
请参阅图10，图10是本申请第八实施例中的电子装置的正面结构示意图。本申请电子装置的第八实施例的结构与第一实施例的结构相似，不同之处在于：在第八实施例中，除了所述支撑片31与保护层334之间的左右侧边处分别设置有条形状的胶水50外，所述支撑片31与保护层334之间于可折弯区域3320内还设置有若干条形状的相互间隔的胶水50，若干条形状的所述胶水50沿所述屏体332的宽度方向排列。每一条形状的胶水50包括若干间隔的点胶区56，同一条形状的胶水50的若干所述点胶区56沿所述支撑片31的侧边线性排列，即，若干所述点胶区56沿所述屏体332的外侧的长度方向阵列，相邻的两个点胶区556之间通过间隙相互隔开。。
本实施例中，每一点胶区56呈矩形。本实施例中的若干点胶区56能使支撑片31与保护层334连接更牢固，且能节省胶水50的用量。并且，由于各点胶区556内的胶水50为相互独立，即使一个点胶区556内的胶水失效，也不会牵连其他位置的点胶区556内的胶水，从而使得电子装置整体的结构更为稳固。
请参阅图11，图11是本申请第九实施例中的电子装置的正面结构示意图。本申请电子装置的第九实施例的结构与第八实施例的结构相似，不同之处在于：在第九实施例中，除了支撑片31与保护层334之间的左右侧边处分别设置有由条形状的胶水50外，所述支撑片31与保护层334之间于可折弯区域3320内的每一条形状的胶水50包括若干相互间隔的圆形的点胶区56。若干圆形的点胶区56能使支撑片31与保护层334连接更牢固，且能节省胶水50的用量。
请参阅图12，图12是本申请第十实施例中的电子装置的正面结构示意图。本申请电子装置的第十实施例的结构与第八实施例的结构相似，不同之处在于：在第十实施例中，所述支撑片31与保护层334之间于可折弯区域3320 内的若干相互间隔的胶水50均包括若干相互间隔的棱形的弹性胶片54。若干棱形的点胶区56能使支撑片31与保护层334连接更牢固，且能节省胶水50的用量。
在其他实施例中，每一点胶区56还可以是多边形、椭圆形或不规则图形等。
其他实施例中，所述保护层334面朝所述支撑片31的侧面或所述支撑片31面朝所述保护层334的侧面开设有若干收容槽，若干所述收容槽沿所述柔性屏33的宽度方向分布，每一收容槽沿所述柔性屏33的外侧的长度方向排列，每一收容槽内填充有所述胶水50。
其他实施例中，沿所述柔性屏33的外侧的长度方向的每一收容槽包括相互间隔的若干凹陷，每一凹陷内填充有所述胶水50每一凹陷可以呈矩形、棱形、圆形、椭圆形或不规则图形等。
可以理解地，除柔性屏板外，本发明的柔性屏也可以不包含或仅包含遮光黑胶层、保护层及盖板其中的任一种或多种或所有。
上述各实施例的固化后的胶水50具有弹性，因而可以在支撑片31相对柔性屏33滑动时产生拉伸形变，当支撑片31与柔性屏33的相对位置恢复时，固化后的胶水50由于自身的弹性将自动收缩形变恢复初始状态，而不会出现被拉断的情况。进一步地，固化后的胶水50的形变程度与支撑片31相对柔性屏33的滑动距离成比例关系，即满足c 2＝a 2+b 2，其中c为固化后的胶水50拉伸变形之后的长度，a为支撑片31相对于柔性屏33的滑动距离，b为支撑片31与柔性屏33之间在厚度方向上的距离。换句话说，固化后的胶水50的拉伸幅度满足
Figure PCTCN2018096871-appb-000001
设定当支撑片31相对柔性屏33滑动方向为X，支撑片31的厚度方向为Y，当支撑片31相对柔性屏33滑动时，固化后的胶水50沿着相对X及厚度方向Y均倾斜的方向拉伸变形，固化后的胶水50的拉伸方向倾斜于保护层334相对支撑片31的滑动方向。
