请一并参阅图1至图4，图1是本申请第一实施例中的电子装置的立体结构示意图；图2是图1的正面结构示意图；图3是图1中沿III-III线的部分剖视图；图4是图3中的显示装置与壳体的分解图。本申请的第一实施例中的电子装置100，包括一壳体20及设置于所述壳体20上的一显示装置30。所述壳体20包括一中框架21及铰链25，所述中框架21包括一第一框体及一第二框体，所述铰链25连接于所述第一框体与所述第二框体之间。所述显示装置30包括一显示屏32，所述显示屏32的外侧面上设置有密封胶35，所述密封胶35用于防止外部物件如湿气、灰尘等进入所述显示屏32的内部。本申请中，所述显示装置30为柔性显示装置，所述显示屏32为柔性显示屏，所述柔性显示屏包括设置于铰链25上的可折弯区域322，以及位于所述可折弯区域322相对的两侧的两个非折弯区域324。所述可折弯区域322的背面贴接于所述铰链25，两个非折弯区域324的背面分别设置于所述第一框体与所述第二框体上。位于可折弯区域322的所述密封胶35具有弹性，当所述电子装置100通过所述铰链25折弯或展平时，所述显示屏32的可折弯区域322随所述铰链25折弯或展平，所述密封胶35对应所述可折弯区域322发生弹性形变。
所述显示屏32的正面指面朝所述显示屏32的出光面的面，所述显示屏32的背面指背朝所述出光面的面。
本实施例中，所述电子装置100例如是，但不局限于手机、平板电脑、显示器、液晶面板、OLED面板、电视、智慧手表、VR头戴显示器、车载显示器等其它任何具有显示功能的产品和部件。
本申请电子装置100的显示装置30的显示屏32的外侧面设置有密封胶35。因此，密封胶35能防止外部的湿气、水或灰尘等外部物件进入所述显示屏32的体内，对所述显示屏32具有保护作用，以确保所述显示屏32能正常工作；另外，所述密封胶35能使所述显示屏32的外侧面整齐，能改善所述显示屏32的外观。
如图3所示，所述显示屏32包括一屏体33及层叠于所述屏体33正面的盖板34，所述盖板34的四周外侧面延伸出所述屏体33的四周外侧面，所述盖板34的四周外侧面延伸出所述屏体33的部分与所述屏体33的四周外侧面之间围成一填胶槽36，所述密封胶35收容于所述填胶槽36内。
所述屏体33包括一柔性屏板331，层叠于所述柔性屏板331的背面的一光学胶层333，以及层叠于所述光学胶层333背面的一保护层335。所述柔性屏板331即为显示图像的主体，所述盖板34层叠于所述柔性屏板331的正面。所述盖板34的宽度大于所述柔性屏板331的宽度，所述盖板34的长度大于所述柔性屏板331的长度，即，所述盖板34的左右两侧分别延伸出所述柔性屏板331的左右两侧，所述盖板34相对的两端分别延伸出所述柔性屏板331相对的两端。所述光学胶层333可以是遮光黑胶层，所述光学胶层333及所述保护层335的宽度及长度与所述柔性屏板331相同。所述屏体33的四周外侧面与所述盖板34延伸出所述柔性屏板331部分的背面之间围成所述填胶槽36。所述填胶槽36沿所述屏体33的四周外侧面延伸。所述盖板34的宽度及长度均大于柔性屏板331的宽度及长度的目的在于防止在点密封胶35时，密封胶35满溢到盖板34上方而造成外观不良的情况。
本申请中的盖板34的正面指背朝所述屏体33的出光面的面，所述盖板34的背面指面朝所述屏体33的出光面的面。
本实施例中，填胶槽36内于所述盖板34的背面及所述屏体33的四周外侧面与所述保护层335的背面邻近所述填胶槽36处均通过自动点胶设备设置有所述密封胶35，使所述密封胶35密封盖板34与所述屏体33之间的细缝，以及所述屏体33的各层叠模层之间的细缝，能防止湿气或灰尘等外部物件进入。因此，本实施例中的密封胶35从所述屏体33的四周外侧面覆盖至背面。
在其他实施例中，也可以仅在所述填胶槽36内的盖板34的背面与所述屏体33的四周外侧面之间设置密封胶35，即，所述屏体33的背面没有覆盖所述密封胶35，以节省所述密封胶35的用量。本实施例中的所述密封胶35也能密封所述保护层335与所述支撑片38之间的细缝，以及所述屏体33的各层叠模层之间的细缝。
在其他实施例中，所述光学胶层333及所述保护层335的宽度及长度与所 述柔性屏板331可以不相同，即，所述光学胶层333的四周外侧面延伸至对应的填胶槽36内，使屏体33的填胶槽36内的柔性屏板331、光学胶层333及保护层335的四周外侧部呈锯齿形状，从而使所述密封胶35与所述屏体33的四周外侧面粘贴更牢固。
所述密封胶35是光敏胶，即，在所述填胶槽36内点胶完成后，所述密封胶35通过紫外光照射后能固化，此时，所述密封胶35固化成具有弹性的固态胶。
所述保护层335可以是硅胶、泡棉、薄金属片如铜箔、液态金属片、记忆合金或其他符合材料。
本实施例中，所述保护层335是液态金属片，所述保护层335的正面贴接于所述光学胶层333的背面，所述保护层335的背面贴接于所述中框架21及铰链25上。当所述电子装置100通过所述铰链25折弯或展平时，所述保护层335对应所述可折弯区域322的区域随所述铰链25折弯或展平。
本发明所称液态金属是指将合金加热到熔融态，然后以超快的冷却速度冷却，使合金晶格来不及有序排列结晶便固化，因为是非结晶状态，像玻璃，所以又被称为非晶合金、液态金属或金属玻璃。液态金属的特性是长程无序(短程有序)、亚稳态、一定程度上的物理特性各向同性、没有确切熔点、具有玻璃转化温度点等，具有固态、金属、玻璃的特性，可以在一定条件下具有高强度、高硬度、塑性、热传导和耐磨性等。也就是说，本发明所称的液态金属在常温实质上是固态的，只不过其某些特性接近液体，所以称之为液态金属。所述液态金属可以为铜、钛、铁、锆、银、镍、镓、金、锑、镉、锌、铟、硅等中一种或多种材料的合金材料，具体金属优选可获得更低的弹性模量、硬度、延伸性等其他力学性质。
本实施例中，所述保护层335覆盖所述屏体33的背面的可折弯区域322及非折弯区域324，这种全覆盖的方式可以避免在保护层335的相对两侧出现段差，导致屏体33出现褶皱或外观不良的情况。
在其他实施例中，所述保护层335也可以仅覆盖所述屏体33的背面的可折弯区域322。
本实施例中选用液态金属片作为保护层335的原因在于液态金属片的耐磨性较佳，当其通过光学胶层333等方式贴设于柔性屏板331的背面时，不仅 可以支撑所述柔性屏板331，并且可以有效地抵御铰链25对其产生的摩擦，不易出现磨损的情况。另一方面，液态金属片的弹性模量较低，可将其直接粘贴在柔性屏板331的背面，在柔性显示装置30弯曲时可跟随屏体33一起同步或近似同步拉伸，从而避免柔性显示装置30在弯曲时由于拉伸幅度差异较大导致出现破损的情况。液态金属可选用铜基、钛基、铁基、锆基、银基、镍基、镓基、金基、锑基、镉基、锌基、铟基、硅基等液态金属，并且，相比于现有的弹性模量更低的材料，如硅胶、泡棉、塑胶等，液态金属的强度更高，且耐磨性更佳，可有效地对柔性屏进行支撑。
在其他实施例中，所述保护层335还可以是软质耐磨塑胶片、软质耐磨橡胶片或软质硅胶片等。
所述盖板34是透光的、且耐弯曲的薄片，本实施例中，所述盖板34为超薄玻璃盖片，所述超薄玻璃盖片的厚度为微米级。
本实施例中选用超薄玻璃盖片作为盖板34的原因在于超薄玻璃盖片具有较好的耐弯曲性、高强度、高硬度等优点，当超薄玻璃盖片贴设于屏体33的正面时，所述超薄玻璃盖片不仅可以随所述屏体33弯曲或展平，并且可以有效地抵御外部物件对超薄玻璃盖片划伤，不易出现磨损的情况。其次，超薄玻璃盖片的弹性模量较低，可将其直接粘贴在屏体33的正面，在显示装置30弯曲时可跟随屏体33一起同步或近似同步拉伸，从而避免显示装置30在弯曲时由于拉伸幅度差异较大导致出现破损的情况。另一方面，所述超薄玻璃盖片的透光率高，方便所述屏体33的光线的射出，且长时间使用后，所述超薄玻璃盖片也不会出现变色等老化问题。
在其他实施例中，所述盖板34也可以是柔性的透明盖板。
所述显示装置30还包括连接于所述中框架21与所述显示屏32之间的支撑片38，所述支撑片38用于将所述显示屏32支撑于所述中框架21及所述铰链25上。本实施例中，所述支撑片38是能弯曲的薄钢片，所述支撑片38的宽度及长度小于所述保护层335的宽度及长度。支撑片38可通过粘胶、螺丝等活动连接于铰链上。
所述中框架21对应所述显示装置30的四周外侧面开设有一收容槽212，所述显示装置30的显示屏32的四周外侧的密封胶35收容于所述收容槽212 内。
密封胶35收容于收容槽212内之后与收容槽212的内壁固定，从而将显示屏32的侧边固定于中框架21上。
进一步地，在非折弯区域324，显示屏32的侧边与中框架21是通过密封胶完全固定住的，即显示屏32的侧边与中框架21不可相对移动，因此位于非折弯区域324的密封胶35在折弯时不发生变形。在可折弯区域322，显示屏32的侧边与支撑片38的侧边通过密封胶35活动连接，即显示屏32的侧边与支撑片38的侧边在弯折时将相对移动，此时密封胶35将发生弹性形变而保持连接显示屏32及支撑片38的状态。可以理解地，非折弯区域324的密封胶35的材质可不同于可折弯区域322的密封胶35的材质，优选地，非折弯区域324的密封胶35的弹性小于可折弯区域322的密封胶35的弹性。当然，两者材质也可相同。
请一并参阅图5至图7，图5至图7是图1中的电子装置的制造过程示意图。本申请的电子装置100的密封胶35是通过自动点胶设备200进行点胶的，具体制造过程如下：
提供所述显示屏32，并将所述显示屏32倒立放置于一支撑面500上，即，使所述显示屏32的盖板34背朝所述屏体33的面放置于支撑面500上；
通过所述自动点胶设备200向所述填胶槽36内及所述屏体33的背面四周邻近所述填胶槽36处进行点胶，使所述密封胶35覆盖所述盖板34延伸出所述柔性屏板331部分的背面、屏体33的四周外侧面，以及屏体33的背面四周邻近所述填胶槽36处；
将固化密封胶35后的显示屏32安装至所述壳体20上，即，所述显示屏32通过所述支撑片38连接于所述中框架21上，固化后的密封胶35收容于所述述中框架21的收容槽212内。
本申请中将所述显示屏32倒立放置后再进行点胶，能准确地控制所述密封胶35的用量，方便观察显示屏32的点胶情况，当出现胶量不足时，可以方便进行补充弹性胶35；另外，也方便所述电子装置100的组装。
请参阅图8，本申请还提供一种显示装置的制作方法，其包括如下步骤：
S1:提供显示装置30，所述显示装置30包括显示屏32；
S2:提供壳体20，所述壳体20对应所述显示屏32的四周外侧面设有收容槽212；及

所述密封胶35通过倒置点胶的方式设置于所述填胶槽36内。在倒置点胶时，所述盖板34位于所述屏体33的下方，所述密封胶35覆盖所述屏体33的四周外侧面及所述盖板34延伸超出所述屏体33的四周外侧面的背面。
所述填胶槽36内的密封胶35通过自动点胶设备200加入。
所述密封胶35覆盖所述盖板34延伸超出所述屏体33的四周外侧面的背面、所述屏体33的四周外侧面，以及所述屏体33的背面四周邻近所述胶槽36处。
所述密封胶35是光敏胶，所述密封胶35在光照的条件下固化成弹性胶体。
请一并参阅图9及图10，图9是本申请第二实施例中的电子装置的结构示意图；图10是图9中的电子装置的制造示意图。本申请的第二实施例中的电子装置的结构与第一实施例中的电子装置100的结构相似，不同之处在于，所述第二实施例中的电子装置的制造过程与方法不同。第二实施例中的电子装置的制造过程如下：
提供所述显示屏32及所述壳体20；
通过自动点胶设备向所述壳体20的中框架21的收容槽212内进行点密封胶35，使部分密封胶35粘接所述中框架21的内表面；
再将所述显示屏32的背面贴合于所述中框架21上，使显示屏32的四周外侧粘贴于所述密封胶35上，即，所述显示屏32的填胶槽36及屏体33的背面邻近所述填胶槽36处均覆盖有密封胶35。最后，固化所述密封胶35。
本实施例中的密封胶35连接于所述显示屏32的四周外侧与所述壳体20的中框架21的收容槽212之间。在所述中框架21的收容槽212内直接点所述密封胶，无需准确地控制点胶的胶量，点胶流程短，提高了生产效率。

请参阅图15，图15是本申请第六实施例中的电子装置的结构示意图。本申请的电子装置的第六实施例的结构与第二实施例的结构相似，不同之处在于，在第六实施例中，所述保护层335的背面的四周于邻近所述填胶槽36处凸设有若干定位块3354，所述密封胶35覆盖所述填胶槽36、所述保护层335的四周外侧面，以及所述保护层335的背面的四周的定位块3354上，从而使所述密封胶35与所述显示屏32的四周外侧面以及收容槽212的内表面粘贴更牢固。
