本申请要求于2019年09月06日提交中国专利局、申请号为201910844376.3、申请名称为“头戴式显示装置及其制备方法”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中。
技术领域
本申请涉及电子产品技术领域，尤其涉及一种头戴式显示装置的制备方法和头戴式显示装置。
背景技术
虚拟现实(virtual reality，VR)眼镜是一种能够将虚拟图像显示给用户观看的眼镜。然而，由于传统的虚拟现实眼镜的抗冲击性能较差，使得虚拟现实眼镜在发生跌落或者与外界物体发生碰撞时，虚拟现实眼镜容易发生损毁，导致虚拟现实眼镜的用户体验性较差。
发明内容
本申请提供一种头戴式显示装置的制备方法和头戴式显示装置，经该方法制备的头戴式显示装置的抗冲击性能较佳。
第一方面，本申请提供一种头戴式显示装置的制备方法。所述方法包括：
在镜头的镜筒的第一面上，形成第一胶量的热熔胶和第二胶量的紫外光-湿气双固化胶，或者形成第三胶量的热熔胶和第四胶量的紫外光固化胶；
将所述显示屏移动至安装位置，以使所述显示屏接触所述热熔胶与所述紫外光-湿气双固化胶，或者所述热熔胶与所述紫外光固化胶；以及
固化所述热熔胶和所述紫外光-湿气双固化胶，或者固化所述热熔胶和所述紫外光固化胶。
可以理解的是，通过上述方法所制备的头戴显示装置在发生掉落或者与其他物体发生触碰时，连接于所述显示屏与所述第一部分的所述热熔胶能够缓冲部分应力从而避免所述头戴式显示装置发生损坏，也即所述头戴式显示装置具有较佳的抗冲击性能。
此外，因为所述紫外光-湿气双固化胶或者所述紫外光固化胶的固化速度较快，所以在所述显示屏与所述镜筒的连接过程中，可以加快所述显示屏与所述镜筒的连接速度。此外，因为紫外光-湿气双固化胶或者所述紫外光固化胶不用通过加热工序来实现固化，所以在紫外光-湿气双固化胶或者所述紫外光固化胶的固化过程不会对所述显示屏造成损伤。此外，因为紫外光-湿气双固化胶是通过紫外光照射而发生固化，也即紫外光-湿气双固化胶无需通过加热工艺固化，所以在热熔胶在固化过程中，热熔胶不会因紫外光-湿气双固化胶的加热工艺而产生二氧化碳，从而造成固化形成的热熔胶体内部膨胀，进而造成热熔胶体的厚度显著增加。
一种实施方式中，所述第一胶量和所述第二胶量通过以下方法确认：
将镜头和显示屏移动至拍摄器件的同一侧，且所述镜头位于所述显示屏与所述拍摄器件之间；
移动所述显示屏至多个不同的位置，且所述显示屏处于各个位置时，均通过所述拍摄器件获取所述显示屏经所述镜头形成的虚像；
依据多个所述虚像形成多个调制传递函数值；
确认所述显示屏的安装位置，所述安装位置为所述多个调制传递函数值中最大的调制传递函数值所对应的所述显示屏的位置；
根据所述安装位置确认所述第一胶量和确认所述第二胶量。
可以理解的是，当调制传递函数值最大时，所述拍摄器件所拍摄的虚像较清楚，也即当用户佩戴所述头戴式显示装置时，用户看到的虚拟图像较清楚。此时，根据所述安装位置确认第一胶量和第二胶量，能够保证当所述显示屏固定连接于所述镜筒时，所述显示屏处于安装位置，从而保证用户清楚地观看所述显示屏所显示的虚拟图像。
一种实施方式中，所述拍摄器件的位置为当用户佩戴所述头戴式显示装置时，用户双眼的所在位置。此时，当调制传递函数值最大时，所述拍摄器件所拍摄的虚像较清楚，也即用户看到的虚拟图像较清楚。此时，根据所述安装位置确认第一胶量和第二胶量，能够保证当所述显示屏固定连接于所述镜筒时，所述显示屏处于安装位置，从而保证用户能够更加清楚地观看所述显示屏所显示的虚拟图像。
一种实施方式中，在根据所述安装位置确认第一胶量和第二胶量的方法中包括：
确认处于所述安装位置的非显示面与所述第一部分之间的第一距离，以及处于所述安装位置的所述非显示面与所述第二部分之间的第二距离，所述非显示面为所述显示屏朝向所述第一面的部分表面；
确认所述第一部分的第二面积以及所述第二部分的第一面积；
根据所述第一距离与所述第二面积确认所述热熔胶的第一胶量，以及根据所述第二距离与所述第一面积确认所述紫外光-湿气双固化胶的第二胶量。
可以理解的是，通过上述方法，可以准确地计算出的第一胶量和第一胶量，此时，当所述显示屏通过热熔胶与紫外光-湿气双固化胶固定连接于镜筒时，热熔胶与紫外光-湿气双固化胶不会因胶量太多而流至所述显示面，从而影响所述显示面的显示效果。当然，热熔胶与紫外光-湿气双固化胶不会因胶量太少而降低所述显示屏与所述镜筒的连接牢固度。
一种实施方式中，在确认所述第一距离和所述第二距离的方法中包括：
确认所述第一部分在所述第一方向的第一坐标，所述第二部分在所述第一方向的第二坐标，所述第一方向为所述第一面朝向所述非显示面的方向；
将所述显示屏移动至第一位置，并确认所述非显示面在第一方向的第三坐标，所述第一位置与所述安装位置不同；
将所述显示屏移动至所述安装位置，并根据所述显示屏在第一方向的移动量以及所述第三坐标确认所述非显示面的第四坐标；
根据所述第一坐标与所述第四坐标确认所述第一距离，根据所述第二坐标与所述第四坐标确认所述第二距离。
可以理解的是，通过上述方法，可以准确地测量第一距离和第二距离。
一种实施方式中，采用激光位移传感器确认所述第一坐标、所述第二坐标和所述第三坐标。可以理解的是，因为激光位移传感器能够准确测量两点之间的距离，所以采用激光 位移传感器确认的所述第一坐标、所述第二坐标和所述第三坐标的准确度更佳。

以所述第一面所在的平面定义为基准面；
确认所述第一坐标的值为零，所述第二坐标的值为零。
可以理解的是，在本实施方式中，省去了通过激光位移传感器确认第一坐标和第二坐标的步骤，从而可以显著地降低头戴式显示装置的制备成本。
一种实施方式中，确认所述第一距离和所述第二距离的方法中包括：
确认所述第一部分在第一方向的第一坐标，所述第二部分在所述第一方向的第二坐标，所述第一方向为所述第一面朝向所述非显示面的方向；
将所述显示屏移动至所述安装位置，并确认所述非显示面在所述第一方向的第三坐标；
根据所述第一坐标与所述第三坐标确认所述第一距离，根据所述第二坐标与所述第三坐标确认所述第二距离。
可以理解的是，通过上述方法可以准确地确认第一距离和第二距离，且相较于上述方法，本实施方式的方法省去检测了所述显示屏处于第一位置的坐标，从而显著地降低头戴式显示装置的制备成本。
一种实施方式中，采用激光位移传感器确认所述第一面积与所述第二面积。
一种实施方式中，通过紫外光源固化所述紫外光-湿气固化胶，或者所述紫外光固化胶。可以理解的是，通过紫外光光源固化所述紫外光-湿气固化胶，或者所述紫外光固化胶，可以避免因通过加热工序固化紫外光固化胶而对所述显示屏或者所述镜头产生损坏。
一种实施方式中，所述热熔胶的固化方法包括：
所述热熔胶通过自然冷却固化为第一胶体；
所述第一胶体吸收空气中的水汽固化为热熔胶体。
可以理解的是，通过自然冷却固化所述热熔胶，可以避免因通过加热工序固化所述热熔胶而对所述显示屏或者所述镜头产生损坏。
一种实施方式中，所述镜筒具有第一连接位置。所述第一面包括第三部分。所述第三部分连接于所述第一部分，且与所述第二部分错开。所述第一连接位置位于所述第三部分内。在所述热熔胶完成固化后所述方法还包括：
将所述镜架固定连接于所述第一连接位置。
可以理解的是，当所述镜架固定连接于所述第一连接位置时，所述头戴式显示装置的抗冲击性能较佳。具体的，当所述头戴式显示装置发生掉落或者发生碰撞时，外界物体对所述头戴式显示装置施加的外力通过所述第一连接位置传导至所述显示屏。由于所述第一连接位置靠近所述第一部分设置，所以设置于所述第一部分的热熔胶可以快速地缓冲掉该部分应力，进而避免所述显示屏发生破裂或者损坏。
一种实施方式中，所述第三胶量和所述第四胶量通过以下方法确认：
将镜头和显示屏移动至拍摄器件的同一侧，且所述镜头位于所述显示屏与所述拍摄器件之间；
移动所述显示屏至多个不同的位置，且所述显示屏处于各个位置时，均通过所述拍摄 器件确认所述显示屏经所述镜头形成的虚像；
依据多个所述虚像形成多个调制传递函数值；
确认所述显示屏的安装位置，所述安装位置为所述多个调制传递函数值中最大的调制传递函数值所对应的所述显示屏的位置；
根据所述安装位置确认所述第三胶量和确认所述第四胶量。
可以理解的是，当调制传递函数值最大时，所述拍摄器件所拍摄的虚像较清楚，也即当用户佩戴所述头戴式显示装置时，用户看到的虚拟图像较清楚。此时，根据所述安装位置确认第三胶量和第四胶量，能够保证当所述显示屏固定连接于所述镜筒时，所述显示屏处于安装位置，从而保证用户清楚地观看所述显示屏所显示的虚拟图像。
第二方面，本申请提供一种头戴式显示装置。所述头戴式显示装置由上述任一项所述的头戴式显示装置的制备方法制成。通过上述方法制备的头戴式显示装置的抗冲击性能较佳。
第三方面，本申请提供一种头戴式显示装置。头戴式显示装置包括镜头、显示屏及连接胶体。所述镜头包括镜筒和镜片。所述镜筒包括第一面及贯穿所述第一面的通孔。所述镜片连接于所述通孔的孔壁。所述连接胶体位于所述第一面与所述显示屏之间。所述第一面包括第一部分及第二部分。所述连接胶体包括固定连接所述第一部分与所述显示屏的热熔胶体，及固定连接所述第二部分与所述显示屏的紫外光-湿气双固化胶体或者紫外光固化胶体。
可以理解的是，通过在所述第一部分设置所述热熔胶体，所述第二部分设置所述紫外光-湿气双固化胶体或者所述紫外光固化胶体，从而使得所述显示屏能够稳定且牢固地连接在所述镜筒上。此外，因为所述热熔胶体的杨氏模量较小，即所述热熔胶体的弹性较佳，所以当所述头戴式显示装置发生掉落或者发生碰撞时，所述热熔胶体不容易脱胶，从而使得所述镜筒与所述显示屏不易分离。故而，所述头戴式显示装置的抗冲击性能较佳。
此外，因为所述紫外光-湿气双固化胶体或者所述紫外光固化胶的固化速度较快，所以在所述显示屏与所述镜筒的装配过程中，可以加快所述显示屏与所述镜筒的连接速度。此外，因为所述紫外光-湿气双固化胶体或者所述紫外光固化胶不用通过加热工序来实现固化，所以在紫外光-湿气双固化胶体或者所述紫外光固化胶的固化过程不会对显示屏造成损伤。
此外，因为紫外光-湿气双固化胶是通过紫外光照射而发生固化，也即紫外光-湿气双固化胶无需通过加热工艺固化，所以在热熔胶在固化过程中，热熔胶不会因紫外光-湿气双固化胶的加热工艺而产生二氧化碳，从而造成固化形成的热熔胶体内部膨胀，进而造成热熔胶体的厚度显著增加。
一种实施方式中，所述热熔胶体与所述紫外光-湿气双固化胶体在第一方向的厚度均在0.05至0.8毫米的范围内，或者所述热熔胶体与所述紫外光固化胶体在第一方向的厚度均在0.05至0.8毫米的范围内，所述第一方向为所述镜筒朝向所述显示屏的方向。
可以理解的是，在此厚度下的所述热熔胶体与所述紫外光-湿气双固化胶体既能够保证所述显示屏与所述镜头的稳定连接，又能够当用户佩戴所述头戴式显示装置时，用户的双眼能够处于较佳的位置观看所述显示屏显示的虚拟图像，从而显著地提高所述头戴式显示 装置的用户体验性。换言之，所述热熔胶体与所述紫外光-湿气双固化胶体在第一方向的厚度不会因太厚而使得所述显示屏离用户的眼睛太远，进而导致用户看不清所述显示屏的虚拟图像或者用户眼睛因聚焦虚拟图像太久而困乏，降低所述头戴式显示装置的用户体验性。
一种实施方式中，所述热熔胶体与所述紫外光-湿气双固化胶体的数量均为多个，所述热熔胶体与所述紫外光-湿气双固化胶体依次交错排布，或者所述热熔胶体与所述紫外光固化胶体的数量均为多个，所述热熔胶体与所述紫外光固化胶体依次交错排布。
可以理解的是，此时，当所述显示屏通过热熔胶体和紫外光-湿气双固化胶体或者所述热熔胶体与所述紫外光固化胶体连接于镜筒时，一方面，所述显示屏与所镜筒之间具有较多的弹性连接区，从而显著地增加所述头戴式显示装置的抗冲击性能，另一方面，当所述显示屏可先通过所述紫外光-湿气双固化胶体或者所述紫外光固化胶体固定连接于镜筒时，具有较多的紫外光-湿气双固化胶体或者所述紫外光固化胶体可以在保证显示屏快速固定连接于镜筒的同时，所述显示屏还能够更加稳定地连接在镜筒上。
一种实施方式中，所述热熔胶与所述紫外光-湿气双固化胶拼接成环状结构，或者所述热熔胶与所述紫外光固化胶拼接成环状结构。此时，所述镜筒与所述显示屏的连接面积较大，从而提高所述镜筒与所述显示屏的连接牢固度。
一种实施方式中，所述镜筒具有第一连接位置，所述第一面包括第三部分，所述第三部分连接于所述第一部分，且与所述第二部分错开，所述第一连接位置位于所述第三部分，所述头戴式显示装置包括镜架，所述镜架连接于所述第一连接位置。
可以理解的是，因为所述第一连接位置位于所述第三部分，且所述第三部分连接于所述第一部分，且与所述第二部分错开，所以所述第一连接位置相较于所述第二部分靠近所述第一部分设置。此时，当所述头戴式显示装置发生掉落或者发生碰撞时，外界物体对所述头戴式显示装置施加的外力，并通过所述第一连接位置传导至所述显示屏。由于所述第一部分设置有所述热熔胶体，所述热熔胶体的弹性较佳，从而通过所述热熔胶体可以快速地缓冲掉该部分应力，进而避免所述显示屏发生破裂或者损坏。

具体实施方式
请参阅图1和图2，图1是本申请实施例提供的头戴式显示装置100在一种角度下的结构示意图。图2是本申请实施例提供的头戴式显示装置100在另一种角度下的结构示意图。头戴式显示装置100可以为虚拟现实(virtual reality，VR)眼镜或者VR头盔。图1和图2所示实施例的头戴式显示装置100以VR眼镜为例进行阐述。可以理解的是，当用户穿戴上头戴式显示装置100时，用户能够通过头戴式显示装置100观看虚拟图像。
如图3所示，图3是图1所示的头戴式显示装置100的分解示意图。
头戴式显示装置100包括镜架10、镜头20、显示屏30及连接胶体40。可选的，镜架10包括镜框11及镜腿12。镜框11可包括用于佩戴在用户鼻部的鼻托。此外，镜腿12用于佩戴在用户的耳部。此时，当用户将头戴式显示装置100佩戴于头部时，通过镜腿12与鼻托可以将头戴式显示装置100稳定地放置在用户的头部。
此外，镜头20的数量为两个。两个镜头20分别安装于镜框11。此时，用户的双眼可通过两个镜头20看到虚拟画面。当然，在其他实施例中，镜头20的数量不做限制。例如镜头20也可以为一个，但镜头20的大小需覆盖用户的双眼。结合附图1和附图2可知，镜头20位于两个镜腿12之间。当用户佩戴上头戴式显示装置100时，镜头20朝向用户。
此外，显示屏30的数量为两个。两个显示屏30一一对应地固定连接于镜头20上，也即每个显示屏30均与一个镜头20对应设置。此时，两个显示屏30分别一一对应地为两个镜头20提供虚拟图像。虚拟图像可以为但不仅限于为三维虚拟图像。请结合图1所示，图1示意了显示屏30穿过镜框11，并露出。在其他实施方式中，显示屏30也可以位于与镜头20同一侧，也即显示屏30未穿过镜框11。可选的，显示屏30可以为但不仅限于为液晶显示屏30(liquid crystal display,LCD)。例如，显示屏30还可以为有机发光二极管显示屏30(OrganicLight-Emitting Diode，OLED)。此外，在其他实施例中，显示屏30的数量也可以为一个。显示屏30通过分区为两个镜头20提供虚拟图像。此外，显示屏30也可以与外部设备无线通信连接。此时，显示屏30能够接收外部设备所提供的虚拟图像，并将所接收的虚拟图像通过镜头20提供给用户。
此外，连接胶体40连接于镜头20与显示屏30之间。连接胶体40能够保证镜头20与显示屏30之间的连接稳定性。
如图4和图5所示，图4是图1所示头戴式显示装置100的部分结构示意图。图5是图4所示的头戴式显示装置100在M-M线处的剖面图。镜头20包括镜筒21和镜片22。镜筒21包括相背设置的第一面212与第二面211。镜筒21设有通孔213。通孔213自第一面212贯穿至第二面211。镜片22连接于通孔213的孔壁。可以理解的是，镜片22可以固定连接于通孔213的孔壁，镜片22也可以活动连接于通孔213的孔壁。连接胶体40位于第一面212与显示屏30之间。
请参阅图6，图6是图4所示的头戴式显示装置100的部分结构的分解示意图。
第一面212包括第一部分2121及第二部分2122。第二部分2122可以与第一部分2121相互连接，也可以与第一部分2121间隔连接。热熔胶体214设置在第一部分2121与显示屏30之间。热熔胶体214经热熔胶固化形成。紫外光-湿气双固化胶体215设置在第二部分2122与显示屏30之间。紫外光-湿气双固化胶体215经紫外光-湿气双固化胶固化形成。此时，显示屏30通过热熔胶体214与紫外光-湿气双固化胶体215固定连接于镜筒21。请结合附图4和图5所示，当显示屏30固定连接于镜筒21时，显示屏30遮盖镜筒21的通孔213。
可以理解的是，通过热熔胶体214将设置在第一部分2121与显示屏30之间，紫外光-湿气双固化胶体215设置在第二部分2122与显示屏30之间，从而使得显示屏30能够稳定且牢固地连接在镜筒21上。此外，因为热熔胶体214的杨氏模量较小，即热熔胶体214的弹性较佳，所以当头戴式显示装置100发生掉落或者发生碰撞时，热熔胶体214不容易脱胶，从而使得镜筒21与显示屏30不易分离。故而，头戴式显示装置100的抗冲击性能较佳。此时，当镜筒21与显示屏30之间不易分离，外界的灰尘或者水汽就不容易进入头戴式显示装置100的内部，从而破坏头戴式显示装置100内部结构。
可以理解的是，因为紫外光-湿气双固化胶的固化速度较快，所以在显示屏30与镜筒21的装配过程中，可以使得显示屏30与镜筒21的快速连接。此外，在紫外光-湿气双固化胶初步固化后，紫外光-湿气双固化胶还能够在后续显示屏30与镜筒21的装配过程中通过吸收环境中的水汽继续固化，从而一方面进一步提高显示屏30与镜筒21的连接牢固度，另一方面，避免环境的水汽对显示屏30或者镜头20产生破坏(例如，水汽破坏显示屏30内部的电路的连接。
此外，因为紫外光-湿气双固化胶是通过紫外光照射而发生固化，也即紫外光-湿气双固化胶无需通过加热工艺固化，所以在热熔胶在固化过程中，热熔胶不会因紫外光-湿气双固化胶的加热工艺而产生二氧化碳，从而造成固化形成的热熔胶体214内部膨胀，进而造成热熔胶体214的厚度显著增加。
一种实施方式中，热熔胶体214与紫外光-湿气双固化胶体215在第一方向的厚度均在0.05至0.8毫米的范围内。第一方向为镜筒21朝向显示屏30的方向。可以理解的是，在此厚度下的热熔胶体214与紫外光-湿气双固化胶体215既能够保证显示屏30与镜头20的稳定连接，又能够当用户佩戴头戴式显示装置100时，用户的双眼能够处于较佳的位置观看显示屏30显示的虚拟图像，从而显著地提高头戴式显示装置100的用户体验性。换言之，热熔胶体214与紫外光-湿气双固化胶体215在第一方向的厚度不会因太厚而使得显示屏30离用户的眼睛太远，进而导致用户看不清显示屏30的虚拟图像或者用户眼睛因聚焦虚拟图像太久而困乏，降低头戴式显示装置100的用户体验性。
一种实施方式中，请再次参阅图5，显示屏30朝向第一面212的表面包括显示面31和连接于显示面31的周缘的非显示面32。附图5中通过虚线将显示屏30分成了中间部分和连接在中间部分的周缘的周缘部分。中间部分朝向镜头20的表面为显示面31。周缘部分朝向镜头20的表面为非显示面32。显示面31正对于通孔213。此时，当用户佩戴上头戴式显示装置100时，用户能够通过通孔213看到显示面31所显示的虚拟图像。结合附图 6所示，显示屏30的非显示面32通过热熔胶体214与紫外光-湿气双固化胶体215固定连接于镜筒21。此时，热熔胶体214与紫外光-湿气双固化胶体215不会影响显示面31的显示。
一种实施方式中，热熔胶体214与所述紫外光-湿气双固化胶体215的数量均为多个。所述热熔胶体214与所述紫外光-湿气双固化胶体215依次交错排布。例如，请再次参阅图6，第一部分2121的热熔胶体214为两个。设置于第二部分2122的紫外光-湿气双固化胶体215的数量也为两个。两个热熔胶体214彼此错开设置。两个紫外光-湿气双固化胶体215彼此错开设置。此时，第一部分2121的数量为两个，第二部分2122的数量也为两个。两个第一部分2121错开设置。两个第二部分2122错开设置。此时，当显示屏30通过热熔胶体214和紫外光-湿气双固化胶体215连接于镜筒21时，一方面，显示屏30与镜筒21之间具有较多的弹性连接区，从而显著地增加头戴式显示装置100的抗冲击性能，另一方面，当显示屏30先通过紫外光-湿气双固化胶体215固定连接于镜筒21时，具有较多的紫外光-湿气双固化胶体215可以在保证显示屏30快速固定连接于镜筒21的同时，显示屏30还能够更加稳定地连接在镜筒21上。在其他实施方式中，第一部分2121的数量和第二部分2122的数量也可以为一个或者大于两个，具体的本申请不作限定。
请再次参阅图6，热熔胶体214与紫外光-湿气双固化胶体215拼接成环状结构。此时，镜筒21与显示屏30的连接面积较大，从而提高镜筒21与显示屏30的连接牢固度。当然，在其他实施方式中，热熔胶体214与紫外光-湿气双固化胶体215也可以间隔环绕形成环状结构。具体的本申请不做限定。
请再次参阅图6，镜筒21具有第一连接位置A。第一面212包括第三部分2123。第三部分2123连接于第一部分2121，且与第二部分2122错开。换言之，第三部分2123靠近第一部分2121设置，远离第二部分2122设置。第一连接位置A位于第三部分2123内。请结合附图1所示，镜架10固定连接于第一连接位置A。附图1示意了镜框11固定连接于第一连接位置A。
可以理解的是，因为第一连接位置A位于第三部分2123内，且第三部分2123连接于第一部分2121，且与第二部分2122错开，所以第一连接位置A相较于第二部分2122靠近第一部分2121设置。此时，当头戴式显示装置100发生掉落或者发生碰撞时，外界物体对头戴式显示装置100施加的外力通过第一连接位置A传导至显示屏30。由于第一部分2121与显示屏30之间设置有热熔胶体214，热熔胶体214的弹性较佳，从而通过热熔胶体214可以快速地缓冲掉该部分应力，进而避免显示屏30发生破裂或者损坏。
一种实施方式中，第一连接位置A的数量为多个。多个第一连接位置A均位于第三部分2123内。此时，当镜架10固定连接于第一连接位置A时，镜架10与镜筒21的连接牢固度较佳。此外，第三部分2123的数量也可以为多个。具体的本申请不做限制。
一种实施方式中，镜筒21的第一连接位置A设有第一安装孔。镜架10设有第二安装孔。通过紧固件穿过第一安装孔与第二安装孔，以将镜筒21锁紧于镜架10上。可以理解的是，紧固件可以为但不仅限于为螺钉、螺丝或者铆钉。在其他实施方式中，镜架10也可以通过焊接、卡扣卡合或者热熔柱等连接方式连接于镜筒21的第一连接位置A。
上文具体描述了第一种实施例，第二部分2122与显示屏30之间设置有紫外光-湿气双 固化胶体215。下文将描述第二种实施例，第二部分2122设置紫外光固化胶体。
第二种实施例，与第一种实施例大部分的相同技术内容不再赘述：第二部分2122设置紫外光固化胶体。紫外光固化胶固化形成紫外光固化胶体。
可以理解的是，因为紫外光固化胶体215的固化速度较快，所以在显示屏30与镜筒21的装配过程中，可以加快显示屏30与镜筒21的连接速度。此外，因为紫外光固化胶体215不用通过加热工序来实现固化，所以在紫外光固化胶体215的固化过程不会对显示屏30造成损伤。
请参阅图7，图7是本申请实施例提供一种的头戴式显示装置100的制备方法的流程示意图。通过本实施例的头戴式显示装置100的制备方法可以制备出头戴式显示装置100。下文将结合附图7具体描述一种头戴式显示装置100的制备方法。该方法包括但不限于包括步骤S100、S200和S300。
S100在镜头20的镜筒21的第一面212上，形成第一胶量的热熔胶和第二胶量的紫外光-湿气双固化胶；
S200将所述显示屏移动至安装位置，以使所述显示屏接触所述热熔胶与所述紫外光-湿气双固化胶；
S300固化所述热熔胶和所述紫外光-湿气双固化胶，或者固化所述热熔胶和所述紫外光固化胶。
在本实施例中，通过上述S100、S200和S300，从而当所制成的头戴式显示装置100发生掉落或者与其他物体发生触碰时，连接于显示屏30与第一部分2121的热熔胶能够缓冲部分应力从而避免头戴式显示装置100发生损坏，也即头戴式显示装置100具有较佳的抗冲击性能。
可以理解的是，因为紫外光-湿气双固化胶的固化速度较快，所以在显示屏30与镜筒21的装配过程中，可以使得显示屏30与镜筒21的快速连接。此外，在紫外光-湿气双固化胶初步固化后，紫外光-湿气双固化胶还能够在后续显示屏30与镜筒21的装配过程中通过吸收环境中的水汽继续固化，从而一方面进一步提高显示屏30与镜筒21的连接牢固度，另一方面，避免环境的水汽对显示屏30或者镜头20产生破坏(例如，水汽破坏显示屏30内部的电路的连接。
此外，因为紫外光-湿气双固化胶是通过紫外光照射而发生固化，也即紫外光-湿气双固化胶无需通过加热工艺固化，所以在热熔胶在固化过程中，热熔胶不会因紫外光-湿气双固化胶的加热工艺而产生二氧化碳，从而造成固化形成的热熔胶体214内部膨胀，进而造成热熔胶体214的厚度显著增加。
下文将结合相关附图具体描述步骤S100、S200和S300。
S100在镜头20的镜筒21的第一面212上，形成第一胶量的热熔胶和第二胶量的紫外光-湿气双固化胶；在本实施例中，第一胶量指的是热熔胶的重量。第二胶量指的是紫外光-湿气双固化胶的重量。当然，在其他实施例中，第一胶量也可以指热熔胶的体积。第二胶量也可以指的是紫外光-湿气双固化胶的体积。
可以理解的是，通过有效地控制热熔胶的胶量和紫外光-湿气双固化胶的胶量，可以避免在热熔胶和紫外光-湿气双固化胶不会因胶量太多而流至显示面31，从而影响显示面31 的显示效果。当然，热熔胶与紫外光-湿气双固化胶不会因胶量太少而降低显示屏30与镜筒21的连接牢固度。
下文将结合附图8(a)和图8(b)具体描述如何确认所述第一胶量和所述第二胶量。图8(a)是图7所示头戴式显示装置的制备方法中的部分流程示意图；图8(b)是图8(a)所示头戴式显示装置在制备过程中的结构示意图；
S110将镜头20和显示屏30移动至拍摄器件200的同一侧，且镜头20位于显示屏30与拍摄器件200之间，具体的，镜头20中的镜筒21的第二面211朝向拍摄器件200，镜筒21的第一面212朝向显示屏30；一种实施方式中，拍摄器件200可以为但不仅限于为工业相机。将镜头20放置于一固定台，固定台具有一贯通孔。镜筒21的通孔213与贯通孔正对设置。拍摄器件200位于固定台背离镜筒21的一侧。此时，拍摄器件200朝向第二面211。通过机械手400抓持显示屏30，并将显示屏30移动至镜筒21背离固定台的一侧。此时，显示屏30的显示面31朝向镜头20。机械手400可以精确地控制显示屏30的移动量，并将显示屏30准确地移动至预定位置。
S120移动显示屏30至多个不同的位置，且显示屏30处于各个位置时，均通过拍摄器件200获取显示屏30经镜头20形成的虚像。一种实施方式中，通过机械手400将显示屏30移动至第一采集位置，以使显示屏30正对于镜筒21中镜片22。此时，通过工业相机采集显示屏30在镜片22中的虚像。换言之，工业相机透过镜片22采集位于第一采集位置的显示屏30的图像。再者，通过机械手400移动显示屏30至第二采集位置，再通过工业相机透过镜片22采集显示屏30的图像。依次类推，通过机械手400移动显示屏30至不同的采集位置，再通过工业相机采集处于不同位置的显示屏30的图像。
S130根据不同的虚像确认不同的调制传递函数值；当显示屏30移动至第一采集位置，且工业相机透过镜片22采集位于第一采集位置的显示屏30的图像之后，工业相机根据所采集的图像计算出第一个调制传递函数值。当显示屏30移动至第一采集位置，且工业相机透过镜片22采集位于第一采集位置的显示屏30的图像之后，工业相机根据所采集的图像计算出第二个调制传递函数值。以此类推，工业相机根据不同的图像计算出不同的调制传递函数值。可以理解的是，因为处于不同位置的显示屏30在镜片22中所成的虚像的清晰度不同，所以计算出的调制传递函数值不同。
S140确认显示屏30的安装位置为调制传递函数值最大时所对应的显示屏30的位置；可以理解的是，因为调制传递函数值不同，所以调整传递函数值将存在最大值。此时，确认最大的调制传递函数值所对应的显示屏30的位置，并将该位置确认为显示屏30的安装位置。
S150根据安装位置确认第一胶量和确认第二胶量。
可以理解的是，当调制传递函数值最大时，拍摄器件200所拍摄的虚像较清楚，也即当用户佩戴所述头戴式显示装置100时，用户看到的虚拟图像较清楚。此时，根据所述安装位置确认第一胶量和第二胶量，能够保证当所述显示屏30固定连接于所述镜筒21时，所述显示屏30处于安装位置，从而保证用户清楚地观看所述显示屏30所显示的虚拟图像。
一种实施方式中，拍摄器件200的位置为当用户佩戴头戴式显示装置100时，用户双眼的所在位置。此时，当调制传递函数值最大时，拍摄器件200所拍摄的虚像较清楚，也 即用户看到的虚拟图像较清楚。此时，根据安装位置确认热熔胶的胶量和紫外光-湿气双固化胶的胶量，能够保证当显示屏30固定连接于镜筒21时，显示屏30处于安装位置，从而保证用户清楚地观看道显示屏30所显示的虚拟图像。
下文将通过相关附图具体描述一种确认热熔胶的第一胶量和紫外光-湿气双固化胶的第二胶量的实施方式。请参阅图9，图9是图7所示的头戴式显示装置100的制备方法的部分流程示意图。头戴式显示装置方法还包括但不限于包括S151、S152和S153。S151、S152和S153是上述S150的一种实施方式。为了避免过多赘述，附图9只给出了S151、S152和S153。
S151确认处于安装位置的非显示面32与第一部分2121之间的第一距离L，以及处于安装位置的非显示面与第二部分2122之间的第二距离D；
S152确认第一部分2121的第二面积以及第二部分2122的第一面积；
S153根据第一距离L与第二面211积确认热熔胶的第一胶量，以及根据第二距离D与第一面212积确认紫外光-湿气双固化胶的第二胶量。
在本实施方式中，通过S151、S152和S153的方法，可以准确地计算出的热熔胶量，此时，当显示屏30通过热熔胶与紫外光-湿气双固化胶固定连接于镜筒21时，热熔胶与紫外光-湿气双固化胶不会因胶量太多而流至显示面31，从而影响显示面31的显示效果。当然，热熔胶与紫外光-湿气双固化胶不会因胶量太少而降低显示屏30与镜筒21的连接牢固度。
下文将结合相关附图具体描述步骤S151、S152和S153。
请参阅图10和图11，图10是图1所示的头戴式显示装置的镜筒的结构示意图。图11是图9所示头戴式显示装置100在制备过程中的结构示意图。
S151确认处于安装位置的非显示面32与第一部分2121之间的第一距离L，以及处于安装位置的非显示面32与第二部分2122之间的第二距离D。
可以理解是，当非显示面32与第一部分2121均为平面时，测量非显示面32与第一部分2121上的两点之间的垂直距离。具体的，先确认非显示面32上的第一点，再确认第一部分2121上的第二点。第一点与第二点的连线垂直于非显示面32和第一部分2121。此时，第一点与第二点之间的距离为第一距离L。当非显示面32与显示面至少一个为曲面时，测量非显示面32与第一部分2121上多个两点之间的垂直距离，并对多个垂直距离求平均计算出第一距离L。具体的，先确认非显示面32上的第一点，再确认第一部分2121上的第二点。第一点与第二点的连线垂直于非显示面32和第一部分2121。此时，第一点与第二点之间的垂直距离为第一垂直距离。再确认非显示面32上的第三点，第三点与第一点的位置不同。确认第一部分2121上的第四点。第三点与第四点的连线均垂直于非显示面32和第一部分2121。此时，第三点与第四点之间的垂直距离为第二垂直距离。依次类推，在非显示面32和第一部分2121确认第N垂直距离。此时，将第一垂直距离至第N垂直距离求平均计算出第一距离L。当然，在其他实施方式，也不仅限于通过将第一垂直距离至第N垂直距离求平均计算出第一距离L，也可通过其他数学计算方法求出较准确的第一距离L。
此外，处于安装位置的非显示面32与第二部分2122之间的第二距离D的测量方式可参阅上述的第一距离L的测量方式。这里不再赘述。
可以理解的是，上述具体描述了通过测量至少两个点来实现测量第一距离L。此时，在测量两个点的距离的方式中具有多种，下文将结合附图具体描述两种测量第一距离L的方式。下文将结合附图12和图13来具体描述第一种实施方式。第一种实施方式的方法包括但不限于包括步骤S1511、S1512、S1513和S1514。S1511、S1512、S1513和S1514是上述S151的一种实施方式。为了避免过多赘述，附图12只给出了S1511、S1512、S1513和S1514。请参阅图12和图13，图12是图7所示的头戴式显示装置100的制备方法的部分流程示意图。图13是图12所示头戴式显示装置100在制备过程中的结构示意图。
S1511确认第一部分2121在第一方向的第一坐标A，第二部分2122在第一方向的第二坐标B，第一方向为第一部分2121朝向非显示面32的方向，也即第二面211朝向第一面212的方向；可以理解的是，通过在显示屏30与镜筒21之间设置基准面S，基准面S为平行于第一面212的平面。第一部分2121至基准面S的距离为第一坐标A。第二部分2122至基准面S的距离为第二坐标B(图未示)。
一种实施方式中，采用激光位移传感器500确认第一坐标A和第二坐标B。可以理解的是，通过激光位移传感器500可以准确地测量第一坐标A和第二坐标B。具体的，将激光位移传感器500移动至镜筒21的一侧，且激光位移传感器500朝向第一部分2121。激光位移传感器500位于基准面S。此时，通过激光位移传感器500向第一部分2121发射光线以及接收被第一部分2121反射回的光线来测量第一部分2121与激光位移传感器500在第一方向的第一垂直距离。此时，第一垂直距离为第一坐标A。相同的，通过激光位移传感器500向第二部分2122发射光线以及接收被第二部分2122反射回的光线来测量第二部分2122与激光位移传感器500在第一方向的第二垂直距离。此时，第二垂直距离为第二坐标B。
一种实施方式中，以第一面212所在的平面定义为基准面S。此时，第一面212在第一方向的坐标均为零。此时，确认第一坐标A的值为零，第二坐标B的值为零。在该种实施方式中，省去了采用激光位移传感器500确认第一坐标A和第二坐标B，从而可以显著地降低头戴式显示装置100的制备成本。
请参阅图14，图14是图12所示头戴式显示装置100在制备过程中的结构示意图。
S1512将显示屏30移动至第一位置，并确认非显示面32在第一方向的第三坐标C，第一位置与安装位置不同；
一种实施方式中，采用激光位移传感器500确认第三坐标C。可以理解的是，通过激光位移传感器500可以准确地测量第三坐标C。具体的，将显示屏30移动至第一位置。再将激光位移传感器500移动至显示屏30的一侧，且激光位移传感器500朝向显示屏30的非显示面32。激光位移传感器500位于基准面S。此时，通过激光位移传感器500向非显示面32发射光线以及接收被非显示面32反射回的光线来测量非显示面32与激光位移传感器500在第一方向的第三垂直距离。此时，第三垂直距离为第三坐标C。
一种实施方式中，当第一面212为基准面S时，第三坐标C即为非显示面32与第一面212之间的距离。
S1513将显示屏30移动至安装位置，并根据显示屏30在第一方向的移动量以及第三坐标C确认非显示面32在第一方向的第四坐标E；
一种实施方式中，通过机械手400抓持显示屏30。此时，显示屏30在第一方向的移动量等于机械手400在第一方向的移动量。此时，根据机械手400在第一方向的移动量以及第三坐标C确认非显示面32在第一方向的第四坐标E。例如，当机械手400在第一方向的移动量为-10，第三坐标C为20时，第四坐标E为10。当机械手400在第一方向的移动量为1，第三坐标C为5时，第四坐标E为6。
S1514根据第一坐标A与第四坐标E确认第一距离L。根据第二坐标B与第四坐标E确认第二距离D。例如，第一坐标A为0、第二坐标B也为0，第四坐标E为3，此时，第一距离L为3，第二距离D也为3。考虑到单位问题，以厘米(centimeter，cm)为单位。此时，第一距离L为3厘米。第二距离D也为3厘米。
可以理解的是，通过上述第一种实施方式，可以准确地测量第一距离L和第二距离D。
上文具体描述了确认第一距离L和第二距离D的第一种实施方式，下文将结合相关附图具体描述确认第一距离L和第二距离D的第二种实施方式。
第二种实施方式，与第一种实施方式相同的技术内容不再赘述：确认第一距离L和第二距离D的方法中包括：
请参阅图15至图16，第二种实施方式的方法包括但不限于包括步骤S1515、S1516和S1517。S1515、S1516和S1517是上述S151的另一种实施方式。为了避免过多赘述，附图15只给出了S1515、S1516和S1517。图15是图7所示的头戴式显示装置100的制备方法的部分流程示意图。图16是图15所示头戴式显示装置100在制备过程中的结构示意图。
S1515确认第一部分2121在第一方向的第一坐标A，第二部分2122在第一方向的第二坐标B，第一方向为第二面211朝向第一面212的方向；该步骤的具体实现方式可参阅第一种实施方式。这里不再赘述。
S1516将显示屏30移动至安装位置，并确认非显示面32在第一方向的第三坐标C；
一种实施方式中，以第一面212为基准面，且采用激光位移传感器500测量第三坐标C。在本实施方式中，激光位移传感器500位于显示屏30的周侧面。当激光位移传感器500发射光线，光线投射至显示屏30的周侧面。此时，激光位移传感器500能够接收被反射回的光线。当沿第一方向移动激光位移传感器500时，激光位移传感器500发射的光线穿过显示屏30与镜筒21之间，此时，激光位移传感器500无法接收被反射回的光线。当继续沿第一方向移动激光位移传感器500时，激光位移传感器500发射的光线被镜筒21所遮挡，此时，激光位移传感器500能够接收反射回的光线。故而，通过计算激光位移传感器500在第一方向的移动量可以计算出显示屏30与镜筒21之间的距离，也即非显示面32与第一面212之间的距离。在本实施方式中，通过上述方法可以解决因处于安装位置的非显示面32与第一部分2121之间的距离较小而无法将激光位移传感器500移动至非显示面32与第一部分2121之间的问题。非显示面32与第一面212之间的距离即为第三坐标C。故而，通过上述方法可以准确且快速地测量出第三坐标C。当然，在其他实施方式中，采用微型激光位移传感器500。微型激光位移传感器500可以移动至显示屏30与镜筒21之间，从而准确且快速地测量出第三坐标C。
S1517根据第一坐标A与第三坐标C确认第一距离L，根据第二坐标B与第三坐标C确认第二距离D。例如，第一坐标A为0、第二坐标B也为0，第三坐标C为3，此时，第一 距离L为3，第二距离D也为3。考虑到单位问题，以厘米(centimeter，cm)为单位。此时，第一距离L为3厘米。第二距离也为3厘米。
可以理解的是，通过上述的第二种实施方式，可以准确地测量出第一距离L和第二距离D。
上文具体描述了两种确认第一距离L和第二距离D的实施方式。下文将继续结合附图9和附图10具体介绍如何确认热熔胶和紫外光-湿气双固化胶的相关步骤。
S152确认第一部分2121的第二面积以及第二部分2122的第一面积；
一种实施方式中，第一部分2121与第二部分2122均为规则图形。此时，第一部分2121与第二部分2122根据数学相关公式计算出。例如，第一部分2121与第二部分2122均为长方形。此时，测量出长方形的长和宽，便可以根据长方形的面积公式快速计算出第一部分2121的第二面积与第二部分2122的第一面积。
一种实施方式中，第一部分2121与第二部分2122至少一部分为不规则图形。此时，第一部分2121与第二部分2122可根据以下方法测量出。
采用激光位移传感器确认第二面积与第一面积。具体的，通过激光位移传感器扫描第一部分2121，并计算出在该方向上第一部分2121的第二面积。相同的，通过激光位移传感器扫描第二部分2122，并计算出在该方向上第二部分2122的第一面积。在本实施方式中，通过激光位移传感器能够准确地计算出第二面积和第一面积。
S153根据第一距离L与第二面积确认热熔胶的第一胶量，以及根据第二距离D与第一面积确认紫外光-湿气双固化胶的第二胶量。例如，第一距离L为3厘米，第二面积为10平方厘米。此时，第一部分2121与处于安装位置的非显示面32之间的空间体积为30立方厘米。可以理解是，第一部分2121与处于安装位置的非显示面32之间可以形成30立方厘米的热熔胶。此时，热熔胶的胶量为30立方厘米。当然，在其他实施方式中，也可以再根据热熔胶的密度与体积之积计算出热熔胶的质量。相同的，先计算出紫外光-湿气双固化胶所需的体积，再根据紫外光-湿气双固化胶的密度与体积之积计算出紫外光-湿气双固化胶的质量。
在本实施方式中，通过上述方法计算出的热熔胶的胶量较准确，此时，当显示屏30通过热熔胶与紫外光-湿气双固化胶固定连接于镜筒21时，热熔胶与紫外光-湿气双固化胶不会因胶量太多而流至显示面，从而影响显示面的显示效果。当然，热熔胶与紫外光-湿气双固化胶不会因胶量太少而降低显示屏30与镜筒21的连接牢固度。
上述具体介绍了一种确认热熔胶的胶量和紫外光-湿气双固化胶的胶量的实施方式。该实施方式中，热熔胶的胶量和紫外光-湿气双固化胶的胶量能够准确地测量出。当然，在其他实施方式中，也可通过直接在第一部分2121形成一定量的热熔胶以及在第二部分2122上形成一定量的紫外光-湿气双固化胶。该方法简单易操作。
上文具体描述了一种确认所述胶量下的热熔胶和紫外光-湿气双固化胶。下文将继续结合附图7具体介绍如何将显示屏30装配在镜筒21上。
S200将显示屏30移动至安装位置，以使显示屏30接触于热熔胶与紫外光-湿气双固化胶。
一种实施方式中，利用机械手400将显示屏30移动至安装位置。此时，显示屏30接 触于热熔胶与紫外光-湿气双固化胶。当热熔胶与紫外光-湿气双固化胶固化后，热熔胶固化为热熔胶体。紫外光-湿气双固化胶固化为紫外光-湿气双固化胶体。此时，显示屏30将通过热熔胶体和紫外光-湿气双固化胶体固定连接于镜筒21上。
S300固化热熔胶和紫外光-湿气双固化胶。可以理解的是，热熔胶和紫外光固化胶可以同时固化，也可以分步固化。当热熔胶和紫外光-湿气双固化胶同时固化时，可以节省固化步骤，从而显著降低头戴式显示装置的制备成本。
可以理解的是，通过上述方法可以制备出头戴式显示装置100。
一种实施方式中，通过紫外光源固化所述紫外光-湿气固化胶。可以理解的是，通过紫外光光源固化所述紫外光-湿气固化胶，可以避免因通过加热工序固化紫外光固化胶而对所述显示屏或者所述镜头产生损坏。具体的，当显示屏30接触于热熔胶与紫外光-湿气双固化胶时，打开紫外光源，以使紫外光源发射紫外光线。紫外光线照射于非显示面32与第二部分2122之间的紫外光-湿气双固化胶，以使紫外光-湿气双固化胶发生固化形成紫外光-湿气双固化胶体。此外，紫外光-湿气双固化胶在固化过程中，也可在热熔胶的固化过程中或者头戴式显示装置100的装配过程中通过吸收环境中的水汽继续固化。
一种实施方式中，所述热熔胶的固化方法包括：
所述热熔胶通过自然冷却固化为第一胶体；所述第一胶体吸收空气中的水汽固化为热熔胶体。
可以理解的是，通过自然冷却固化所述热熔胶，可以避免因通过加热工序固化所述热熔胶而对所述显示屏或者所述镜头产生损坏。此外，在热熔胶在固化过程中，热熔胶不会因通过加热工艺而产生二氧化碳，从而造成固化形成的热熔胶体214内部膨胀，进而造成热熔胶体214的厚度显著增加。此外，所述第一胶体吸收空气中的水汽固化为热熔胶体，从而保证水汽不会进入头戴式显示设备100而破坏内部电路。
一种实施方式中，头戴式显示装置100的制备方法还包括：
将镜架10固定连接于第一连接位置A。
一种实施方式中，镜架10通过螺钉锁紧于镜筒21上。具体的，在第三部分2123开设第一安装孔，镜架10开设第二安装孔。螺钉穿过第一安装孔和第二安装孔，以将镜筒21固定连接于镜架10上。在其他实施方式中，通过销钉或者螺丝依次穿过第一安装孔和第二安装孔以将镜架10固定连接于镜筒21上。此外，镜架10也可以通过卡扣卡合、热熔柱或者焊接等方式于镜筒21固定连接。
上文具体描述了一种头戴式显示装置100的制备方法。该方法中的第二部分2122形成有紫外光-湿气双固化胶。在其他实施例中，该方法中的第二部分2122也可以形成有紫外光固化胶。该实施例的方法与上述实施例的大部分的技术内容均相同，这里不再赘述。例如，第三胶量的确认可以参考上述实施的第一胶量的确认方法。第四胶量的确认方法可以参考上述实施例的第二胶量的确认方法。但在该实施例中，不同的是在确认紫外光固化胶的第四胶量的过程中，采用紫外光固化胶的密度。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以所述权利要求的保护范围为准。
