Description

一种显示设备及显示设备的组装工艺
本申请实施例要求于2022年07月13日提交中国国家知识产权局、申请号为202210820431.7,发明名称为“一种显示设备及显示设备的组装工艺”的中国专利申请的优先权，其全部内容通过引用结合在本申请实施例中。
技术领域
本申请实施例涉及电子产品领域，特别涉及一种显示设备及显示设备的组装工艺。
背景技术
显示设备通常包括显示屏和中框，中框设置于显示屏的外围，中框和显示屏组装后，二者周边难免会存在缝隙，目前通常使用密封部件对二者周边缝隙进行密封。密封部件密封是否可靠直接影响显示设备的使用性能。
发明内容
本申请实施例提供一种中框和显示屏之间密封性能比较高的显示设备及显示设备的组装工艺。
在一种具体实施方式中，一种显示设备，包括显示屏和中框，中框包括位于显示屏周向的侧板，显示设备还包括由一种低模量胶固化成型的胶粘体，胶粘体位于显示屏与侧板之间的间隙，并且胶粘体露置于显示屏和侧板之外的外表面形成显示设备的外观胶面，外观胶面为在60°光照射角下的光泽度小于或者等于80Gu的哑光面，胶粘体的杨氏模量范围为20MPa至80MPa。
与当前技术采用两种密封胶填缝而言，本申请实施例打破常规思路，在显示屏与侧板之间间隙仅填充一种低模量胶就能满足显示屏和侧板之间弹性支撑需求，并且溢出间隙的低模量胶固化后又能满足作为显示设备外观表面的需求，尤其对于窄边框显示设备具有重要的意义，这样填缝时仅需在点胶设备中加载一种低模量胶，可以通过一台点胶设备完成侧板与显示屏之间的点胶工艺，工艺简单，成本低，并且本申请实施例中仅使用一种低模量胶对显示屏和侧板之间间隙进行填充，无胶水界面间隙，进液与静电击穿防护可靠性更好。
在一种示例中，低模量胶的粘度范围为2000至8000cps。该粘度范围的低模量胶有利于喷胶工艺实现，也有利于擦胶后形成高质量的外观胶面。
在一种示例中，低模量胶包括单组份聚氨酯胶或双组份聚氨酯胶。单组分聚氨酯胶具有立面涂覆不流淌、施工方便、固化速度快等优点，即使侧板处于非水平状态下也能满足在预定位置滴胶的需求，点胶工艺灵活。双组分聚氨酯胶中的第一组分和第二组分的配比可以调节，因此所获得的双组分聚氨酯胶的性能具有可调性，并且粘合强度大。
在一种示例中，侧板的顶部低于显示屏位于显示侧的外表面，外观胶面圆滑过渡连接显示侧的外表面和侧板的顶部。外观胶面自显示屏一侧向侧板顶部高度逐渐降低，实现显示屏与侧板的圆滑过渡连接。
在一种示例中，中框还包括支撑板，支撑板的周向设置有侧板，显示屏背离显示侧的表面还通过粘接件固定于支撑板。粘接件可以为粘接胶层，粘接胶层在起到进一步固定显 示屏的作用下，还能起到弹性防震作用。粘接胶层与胶粘体可以相连形成一体，提高显示屏与中框的固定能力。
在一种示例中，侧板远离支撑板的端部具有圆滑曲面，圆滑曲面与侧板的内壁面相接。与外端部横截面为矩形的侧板相比，圆滑曲面式侧板从视觉效果上其占宽比比较小，更加符合窄边框设计需求。
在一种示例中，显示屏包括显示模组和透明盖板，透明盖板覆盖于显示模组的显示侧，并且透明盖板周向具有延伸出显示模组外缘的延伸部，间隙包括显示模组和侧板之间的第一缝隙，以及延伸部与侧板之间的第二缝隙。延伸部可以增大显示屏与低模量胶的接触面积，有利于提高显示屏的固定可靠性。
第二方面，本发明还提供了一种显示设备的组装工艺，显示设备包括中框和显示屏，组装工艺包括：
加载步骤：在点胶设备中加装一种低模量胶；
点胶步骤：调整点胶设备的点胶嘴和中框至少其中一者的姿态，以实现在中框周向所有侧板的预定位置点低模量胶；
其中，低模量胶固化成型的胶粘体外观面为在60°光照射角下的光泽度小于或者等于80Gu的哑光面，胶粘体的杨氏模量范围为20MPa至80MPa。
在一种示例中，中框周向包括N段侧板，沿显示屏厚度方向，每一侧板至少点两道胶，每一段侧板通过以下方式进行点胶：调整并保持中框待点胶侧板至第一姿态，控制点胶设备在待点胶侧板的内表面的第一位置进行点胶，第一位置点胶完成后将待点胶侧板调整并保持至第二姿态，控制点胶设备在待点胶侧板内表面的第二位置进行点胶，其中第一位置和第二位置沿显示屏厚度方向间隔预定距离。
在侧板沿厚度方向多位置点胶，有利于在侧板和显示屏的间隙完全充满低模量胶，形成质地均匀的胶粘体，提高显示设备的质量。
在一种示例中，在点胶步骤之前，还预存参考目标于控制器，第一位置和第二位置确定方法包括：以参考目标作为基准，相对参考目标偏移第一距离以获取第一位置；以参考目标作为基准，相对参考目标偏移第二距离以获取第二位置。该方法中以同一参考目标作为两个不同位置的判断标准，工艺逻辑简单，易于实现。
在一种示例中，参考目标通过图像扫描或者人工输入控制器。
在一种示例中，在点胶步骤之后还包括以下步骤：
安装工艺步骤：组装显示屏和中框以使显示屏至少部分位于中框所有侧板围成空间内部，并使低模量胶填充于显示屏和周向侧板之间的间隙，将溢出间隙的部分低模量胶去除以形成显示设备的部分外观面。该示例中可以通过擦除工艺去除低模量胶，工艺简单。
在一种示例中，低模量胶的粘度范围为2000至8000cps。
本申请实施例显示设备的组装工艺中仅使用一种低模量胶对显示屏和侧板之间的间隙进行填缝，可以仅采用一个点胶设备加载一种低模量胶即可完成，工艺简单，成本比较低。

具体实施方式
当前，中框和显示屏之间间隙通常使用密封胶进行密封，密封胶需要具有预定支撑刚度以起到对显示屏弹性支撑的效果，密封胶部分会外溢至间隙外部以形成显示设备的部分外观表面，为了兼顾弹性支撑和外观美观的效果，当前通常会在中框和显示屏的间隙之间填充两种类型密封胶：第一密封胶位于第二密封胶的下部，第二密封胶靠近间隙开口位置，第一密封胶的刚度大于第二密封胶的刚度能够起到对显示屏弹性支撑作用，第二密封胶位于间隙开口位置，在安装显示屏后溢出形成满足设计需求的外观表面。
第一密封胶和第二密封胶通常是在显示屏安装之前滴加至中框相应侧板上，在显示屏安装过程中第一密封胶和第二密封胶填充显示屏和中框侧板间隙，并且第二密封胶能够自间隙溢出形成显示设备的部分外观表面。因第一密封胶和第二密封胶为两种不同的胶水，需要在同一设备至少加载两次胶水或者使用不同设备，填胶工艺效率低，并且在显示屏安装过程中，第一密封胶容易外溢出间隙，影响外观表面成型质量。
另外，第一密封胶和第二密封胶二者界面容易出现分层缺陷，导致外观橘皮、进液、电击穿等问题。
针对以上技术问题，本申请实施例进行了深入研究，提出了一种能够解决上述技术问题的技术方案。
在本申请实施例的描述中，需要说明的是，术语“上”、“下”、“内”、“外”等指示的方位或者位置关系为基于附图所示的方位或位置关系，仅是为了便于描述技术的简洁，而并不是指示或者暗示所指的装置或元件必须具有特定的方位、特定的方位构造和操作，因此不能理解对本发明的限制。
以下，术语“第一”、“第二”等仅用于描述目的，而不能理解指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定“第一”、“第二”等的特征可以明示或者隐含地包括一个或者更多个该特征。
为了使本领域的技术人员更好地理解本发明的技术方案，下面结合附图和具体实施例对本发明作进一步的详细说明。
本申请实施例提供的显示设备可以是手机、平板电脑、可穿戴设备、车载设备、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本、个人数字助理(personal digital assistant，PDA)等移动终端，或者，也可以是数码相机、单反相机/微单相机、运动摄像机、云台相机、无人机等专业的拍摄设备，本申请实施例对显示设备的具体类型不作限制，只要显示屏和中框之间填充有密封胶的设备即可。为了方便理解， 以下以显示设备为手机进行说明。
请参考图1，图1为本申请实施例一种实施例所提供显示设备中的示意图，其中图1中显示设备以手机为例示意。
显示设备至少包括中框200和显示屏，中框200主要有两方面的作用：一方面是对显示设备的其他零部件的安装提供安装基础，即显示设备中其他零部件直接或者间接安装于中框200；另一方面，中框200具有保护其他零部件的外壳，能够对其他零部件起到保护作用。中框200可以为使用强度比较高的合金件，当然也可以为满足使用强度的塑料件。
本申请实施例的中框200包括支撑板220和侧板210，侧板210位于支撑板220周向并且朝向显示屏一侧折弯延伸，支撑板220可以四周均设置侧板210，即支撑板220的360°周向可以均设置侧板210，当然也可以根据具体显示设备所需，仅在支撑板220周向局部区域设置侧板210，所有侧板210围成安装显示屏的空腔区域。对于手机而言，支撑板220的四周均设置有侧板210，即中框200可以包括四个侧板210，两两相对设置，分别位于支撑板220的两对侧边，如图1所示，支撑板220的上侧边、下侧边、左侧边和右侧边均设置有侧板210。相对设置的两侧板210可以结构相同，当然也可以不同。显示屏至少部分位于四个侧板210围成的空间内部。
请结合图2理解，图2为图1所示显示设备中A-A的局部剖视图。显示屏300可以包括显示模组110和透明盖板120，显示模组110能够显示图像以及视频等，显示模组110可以包括触控屏、发光层、背板层和基板层等结构层。显示模组110的具体结构可以根据产品不同而选定。显示模组可以采用液晶显示屏(liquid crystal display，LCD)，有机发光二极管(organic light-emitting diode，OLED)，有源矩阵有机发光二极体或主动矩阵有机发光二极体(active-matrix organic light emitting diode的，AMOLED)，柔性发光二极管(flex light-emitting diode，FLED)，量子点发光二极管(quantum dot light emitting diodes，QLED)等。透明盖板120覆盖于显示模组110的外侧，起到保护显示模组110的作用。透明盖板120可以为玻璃盖板，当然也可以为其他能够起到保护功能的透明材料。
显示屏背离显示侧的表面还通过粘接件固定连接支撑板220，粘接件可以为粘接胶层，粘接胶层与胶粘体可以相连形成一体，提高显示屏与中框的固定能力，在一种示例中粘接件可以为背胶400。
本申请实施例中，显示设备还包括由一种低模量胶固化成型的胶粘体300，胶粘体300位于显示屏和侧板之间间隙，显示屏100和侧板210之间的间隙可以完全填充有胶粘体300，当然，胶粘体300也可以仅填充于显示屏100和侧板210之间间隙的部分空间。胶粘体300露置于显示屏100和侧板之外的外表面形成显示设备的部分外观胶面310，需要说明的是，外观胶面310是指胶粘体300形成的产品外表面。其中外观胶面310为在60°光照射角下的光泽度小于或者等于80Gu(英文：Glossunit，中文光泽单位)的哑光面，本申请实施例是以60°光照射角所获取的光泽度为基准，当然，也可以以其他光照射角所获得的光泽度为判断基准，不同光照射角下所获得的光泽度值可能不同，但是对评价外观胶面310的质量却具有等同效果。
胶粘体300的杨氏模量范围为20MPa至80MPa，也就是说，低模量胶固化成型后的杨氏模量范围大致为20MPa至80MPa。从以上描述可知，胶粘体300为低模量胶固化成型后的结构体，低模量胶为液态粘性胶。胶粘体300的杨氏模量范围在20MPa至80MPa范围其具有的弹性支撑能力能够满足显示设备的设计需求，外观胶面310在60°光照射角下的光泽度小于或者等于80Gu，外观胶面310基本为哑光面，可满足显示设备的外观面需求，尤其适用于窄边框显示设备。
外观胶面310的光泽度数值可以为小于或者等于80Gu的任意数值，当60°光照射角下的光泽度小于或者等于20Gu时，此时外观胶面310大致完全哑光，当60°光照射角下的光泽度介于20Gu至40Gu时，外观胶面310为半哑光。同理胶粘体300的杨氏模量为20MPa至80MPa为任意数值，例如20MPa、30MPa、35MPa、40MPa、50MPa、60MPa、80MPa等均满足弹性支撑的需求。
需要说明的是，低模量胶为本领域内的一类密封胶，关于具体参数本文不做限定，本领域内技术人员也会直接地、明确知晓哪一类胶属于低模量胶。
与当前技术采用两种密封胶填缝而言，本申请实施例打破常规思路，在显示屏100与侧板210之间间隙仅填充一种低模量胶就能满足显示屏100和侧板之间弹性支撑需求，并且溢出间隙的低模量胶固化后又能满足作为显示设备外观表面的需求，尤其对于窄边框显示设备具有重要的意义，这样填缝时仅需在点胶设备中加载一种低模量胶，可以通过一台点胶设备完成侧板与显示屏100之间的点胶工艺，工艺简单，成本体，并且本申请实施例中仅使用一种低模量胶对显示屏100和侧板之间间隙进行填充，无胶水界面间隙，进液与静电击穿防护可靠性更好。
本申请实施例中低模量胶的粘度范围为2000cps至8000cps(英文全称为Centipoise中文为“百分之一泊”或“厘泊”)，该粘度范围内的低模量胶流动性能较好，有利于将显示屏100与侧板之间间隙完全填充，避免二者之间间隙存在间隙，提高显示设备的使用性能及使用寿命。
低模量胶的粘度可以为2000cps至8000cps任意数值，在具体实验中选取了2000cps、3000cps、4000cps、5000cps、6000cps、6000cps、8000cps进行测试，测试结果低模量胶固化成型后均能满足显示设备的设计要求。当然，低模量胶的粘度不限于本文所列举的上述数值，可以为上述范围的任意数值。
本申请实施例中低模量胶可以包括单组分聚氨酯胶，单组分聚氨酯胶具有立面涂覆不流淌、施工方便、固化速度快等优点，即使侧板处于非水平状态下也能满足在预定位置滴胶的需求，点胶工艺灵活。
当然，本申请实施例中低模量胶可以包括双组分聚氨酯胶，其属于双组份反应固化型，双组分聚氨酯胶包括第一组分和第二组分，两个组分是分开包装的，使用前按一定比例配置即可。第一组分为主剂，其是羟基组分，第二组分为固化剂，为含游离异氰酸酯基团的组分。当然第一组分可以为端基NCO(异氰酸酯基)的聚氨脂预聚体。第一组分和第二组分按照一定比例混合生成聚氨脂树脂。第一组分和第二组分的比值大约为10:0.8～1.2.本文不公开上述第一组分和第二组分的具体混合比例并不妨碍本领域内技术人员对于本申请实施例技术方案的理解和实施。
双组分聚氨酯胶中的第一组分和第二组分的配比可以调节，因此所获得的双组分聚氨酯胶的性能具有可调性，并且粘合强度大。
如上文所述中框包括支撑板220和侧板210，为了使显示设备的外观更加美观，并且适合使用者握持，侧板210远离支撑板220的端部具有圆滑曲面211，圆滑曲面211与侧板210的内表面相接，也就是说侧板210的内表面和外表面通过圆滑曲面211圆滑过渡。圆滑曲面211可以为弧形面，或者其他形式的曲面。与外端部横截面为矩形的侧板相比，圆滑曲面式侧板从视觉效果上其占宽比比较小，更加符合窄边框设计需求。
在一种具体示例中，显示设备组装后，显示屏100位于显示侧的外表面高于侧板210的顶部，显示屏100的外表面通过外溢出间隙的胶粘体300的外观胶面310过渡连接侧板顶部，也就是说，显示侧的外表面通过外观胶面310过渡连接侧板顶部。
这样，位置比较高的显示侧外表面通过外观胶面310与位置比较低的侧板顶部形成连续的圆滑过渡面，显示设备的周边边缘形成圆滑的弧形结构，从视觉效果上可以进一步降低边框所占的尺寸，以最大程度的实现窄边框的设计效果。
如上文所述，显示屏100包括显示模组110和透明盖板120，透明盖板120覆盖于显示模组110的显示侧，并且透明盖板120周向具有延伸出显示模组外缘的延伸部121，间隙包括显示模组和侧板之间的第一缝隙201，以及延伸部121与侧板之间的第二缝隙202。低模量胶填充于第一缝隙201和第二缝隙202。填充于第一缝隙201的低模量胶可以对延伸部起到支撑作用。
请参考图6和图7，图6为本申请实施例一种实施例所提供的显示设备的组装工艺流程图；图7为本申请实施例另一种实施例所提供的显示设备的组装工艺流程图。
第二方面，本申请实施例还提供了一种显示设备的组装工艺，具体包括：
S1加载步骤：在点胶设备中加装一种低模量胶；
其中低模量胶的粘度范围可以为2000至8000cps，低模量胶的粘度可以根据点胶设备的胶阀选型、设备参数不同而合理选择。在一种具体示例中，胶水粘度的合适范围2000～8000cps；
S2点胶步骤：调整点胶设备的点胶嘴和中框200至少其中一者的姿态，以实现在中框200周向所有侧板的预定位置点低模量胶；
请参考图7，在一种具体示例中，中框200周向包括N段侧板，沿显示屏100厚度方向，每一侧板至少点两道胶，每一段侧板通过以下方式进行点胶步骤S2可以具体包括：
S21、请结合参考图4，可以先将中框200调节至支撑板220与水平面成n°夹角，然后使中框200保持在该位置，控制点胶设备在待点胶侧板的内表面212的第一位置B进行点胶；图4中示出了位于第一位置B的胶滴301；
第一位置B可以为点位置，当然也可以为垂直于纸面的一条直线或者沿垂直于纸面方向的多个分离的点，例如将中框200调节至支撑板220与水平面成n°夹角后，沿B点垂直于纸面方向在侧板上点胶形成一条直线。
S22、请参考图5，将中框200调节至支撑板220与水平面成m°夹角，然后控制点胶设备在待点胶侧板内表面212的第二位置C进行点胶；图5中示出了位于第二位置C的胶滴302；
当然第二位置C也可以为点位置或者为垂直于纸面的一条直线或者曲线。
其中第一位置B和第二位置C沿显示屏100厚度方向间隔预定距离。
图5中仅示出了在侧板上沿显示屏100厚度方向间隔预定间隙的两个位置点胶的具体实施方式，当然点胶位置可以不局限于本文所述的两个位置，还可以为三个或者三个以上。
在点胶步骤之前，还预存参考目标于控制器，第一位置和第二位置确定方法包括：以参考目标作为基准，相对参考目标偏移第一距离L1以获取第一位置B；以参考目标作为基准，相对参考目标A偏移第二距离L2以获取第二位置C。
也就是说，步骤S2具体包括：调整并保持中框200待点胶侧板至第一姿态，并在待点胶侧板的内表面第一位置B点胶；当第一位置B点胶完成后将待点胶侧板调整并保持至第二姿态，在待点胶侧板内表面的第二位置C点胶。
当然，中框200和点胶设备的点胶嘴位置控制方式不局限于上述描述，还可以同时控制二者的相对位置以实现快速点胶。
请再次参考图4和图5，在点胶步骤之前，可以通过手动输入或者设备的图像扫描部件扫描侧板的上边缘上的线或点A位置坐标为参考目标(例如将点A设为点胶嘴的位置原点)，并将其存储于控制器，相对上边缘A偏移L1即获得第一位置B的位置，当完成第一位置B点胶之后，控制器可以直接根据存储的上边缘A位置，相对A偏移L2即可到达第二位置C。
上述参考目标可以通过图像扫描或者人工输入控制器。
本申请实施例中靠近侧板顶部的胶滴局部超出侧板内表面覆盖侧板的部分顶部。这样便于在侧板和显示屏100外部形成外观胶面310。
本申请实施例中S3安装工艺步骤：组装显示屏100和中框200以使显示屏100至少部分位于中框200所有侧板围成空间内部，并使低模量胶填充于显示屏100和周向侧板之间的间隙，将溢出间隙的部分低模量胶去除以形成显示设备的外观胶面310。
低模量胶固化成型的胶粘体300外观胶面310在60°光照射角下的光泽度小于或者等于80Gu，胶粘体300的杨氏模量范围为20MPa至80Mpa。
本申请实施例显示设备的组装工艺中仅使用一种低模量胶对显示屏100和侧板之间的间隙进行填缝，可以仅采用一个点胶设备加载一种低模量胶即可完成，工艺简单，成本比较低。
本申请实施例中的点胶设备可以为五轴点胶设备，动作灵活性比较高。
本文中应用了具体个例对本申请实施例的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请实施例的方法及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请实施例原理的前提下，还可以对本申请实施例进行若干改进和修饰，这些改进和修饰也落入本申请实施例权利要求的保护范围内。
