具体实施方式
本申请实施例提供一种显示设备，该显示设备可以包括头戴式显示设备，例如可以包括虚拟现实(Virtual Reality，VR)设备和增强现实(Augmented Reality，AR)设备，该显示设备还可以包括手表、手环等具有微型显示屏的设备。
其中，VR指的是通过光学成像系统将数字化的内容投射到人眼，让用户仿佛置身于虚拟世界之中，实现沉浸式虚拟体验。随着VR技术的不断发展，用户能够利用头戴显示装置看到虚拟世界中的画面。
AR是一种实时地计算摄影机影像的位置及角度，并加上相应图像、视频、3D模型的技术。AR头戴显示器设备是一种实现AR技术且可佩戴在人体头部进行展示的穿戴式设备，它通过计算机技术可将虚拟的信息叠加到真实世界，使真实的环境和虚拟的物体能够实时地叠加到同一个画面中，实现两种信息的相互补充，并通过头盔、眼镜等设备在用户的眼前进行画面展示，增强用户的现实感。
对于VR设备或者AR设备来说，其均可以包括显示模组和光学模组两个结构，通过显示模组和光学模组的配合，可以实现将显示模组显示的图像投射到人眼中。显示模组和光学模组共同决定着VR设备或者AR设备的显示效果和成本，其中，显示模组中的显示屏需要适用于小尺寸下的显示，对分辨率、刷新率、重量等特性都具有较高的要求。显示屏例如可以采用硅基OLED(Organic Light-Emitting Diode，有机发光二极管)屏、微米发光二极管Micro-LED屏以及其它类型的屏幕。
作为显示屏的硅基OLED等类型的屏幕的开发周期长，经费高，因此实际应用中，一般会基于当前已量产的屏幕作为显示面板，进行VR设备或AR设备的光学设计。硅基OLED屏等类型的屏幕的电路中引脚数量很高，为了满足引脚的排布，FPC(Flexible Printed Circuit board，柔性电路板)出线处的宽度可以和显示面板的宽度相同，甚至大于显示面板的宽度。FPC的结构强度降低，受力后容易发生损坏，这会导致显示面板安装在VR设备或AR设备的支架中时，显示面板的FPC出线侧无法和支架定位安装。
不难理解，显示模组内的微型屏的定位如果存在误差，经过光学模组内的透镜折射后显示误差会被放大，因此，VR设备和AR设备对微型屏的定位要求较高，微型屏的FPC出线侧无法和支架定位安装，会导致VR设备和AR设备中的显示面板定位精确性低，从而大大影响显示效果。
相关技术中，可以通过增大显示面板的宽度尺寸，使FPC出线侧的显示面板宽度大于FPC的宽度，可以使多出来的宽度部分用来实现显示面板在这一侧的定位，但是，在显示面板的显示区域已经能满足VR设备或AR设备的视场要求时，增大显示面板的宽度尺寸意味着重新定制显示面板，将会引起成本的大幅上升。
另一种相关技术中，显示面板安装在支架的容置仓内，容置仓上未设置定位结构，或者，容置仓上对应于显示面板的除FPC出线侧的其它三条边上设置有定位结构，显示面板通过点胶等方式固定在支架的容置仓内，即通过点胶实现定位和固定。但是，点胶的方式定位精度有限，尤其是对于显示面板的FPC出线侧来说，无法精定位的话，容易产生较大 公差。
基于上述问题，本申请实施例提供一种显示模组和显示设备，通过增加设置盖设在显示面板上的透明盖板，并在支架的容置仓内增加设置定位筋，利用透明盖板的轮廓与容置仓和定位筋相配合，从而可以实现显示面板的精定位固定。
以下，参考附图和具体的实施例对本申请提供的显示模组和显示设备作详细的描述。

示例性地，VR设备100a可以为图中的眼镜的形式，此时，设备主体12可以包括架设在用户鼻梁上方且位于用户眼睛前方的镜架，穿戴部11可以为架设在用户耳朵上的镜腿。VR设备100a也可以为头盔等形式，设备主体12可以为罩设在用户眼睛前方的眼罩，穿戴部11可以为罩设在用户头部的头盔。
设备主体12内设置有光学模组200和显示模组300，光学模组200和显示模组300接管人眼视场内的光线，显示模组300位于光学模组200的远离人眼的一侧，显示模组300可以包括显示面板，显示模组300用来显示实像，光学模组200可以包括光学透镜组和反射镜等结构，显示模组300发出的光线经过光学模组200的折射或反射后进入人眼，光学模组200可以把极近的屏图像呈现拉远至人眼可视范围内的放大虚像，从而使人眼能够清晰的看到屏上的内容。一个光学模组200和一个显示模组300构成一个成像系统，成像系统的数量可以分别为两个，分别对应用户的左眼和右眼设置，两个成像系统可以通过交错显示、画面交换或者视差融合的方式，达到立体显像的目的。
图1b为本申请一实施例提供的AR设备的结构示意图。参考图1b所示，AR设备100b可以包括穿戴部11和设备主体12，用户佩戴AR设备100b时，设备主体12位于用户的眼睛E的前方，用来为用户的眼睛提供显示画面，穿戴部11则用来固定在用户的头部或者耳朵上，实现AR设备100b的可靠佩戴。
实际应用中，本实施例提供的AR设备100b可以为图中的眼镜式形态，此时，设备主体12可以包括架设在用户鼻梁上方且位于用户眼睛前方的镜架，穿戴部11可以为架设在用户耳朵上的镜腿，镜架内设置有光波导13作为镜片。光学模组200和显示模组300可以设置在镜腿上，显示模组300发出的光线，通过光学模组200后，进入到光波导13内，光波导13可以改变光路方向，将虚拟图像投影到人眼中，实现虚拟图像与真实图像的叠加。可选地，AR眼镜也可以设置为头盔式形态，此时，显示镜片10位于头盔的前部，用户穿戴头盔时，显示镜片10位于用户的眼睛前方。
可以理解，无论是VR设备100a还是AR设备100b，为了能够看到更多更清晰的像，光学模组200和显示模组300必须有一个精确的定位，尤其是对于多镜片组成的光学模组200来说，如果光学模组200的镜头未能聚焦或者覆盖显示模组300的显示内容，会造成成像模糊或者内容缺失等问题。同时，显示模组300的显示面板的表面为成像面，显示面板表面点胶宽度有限，因此上述相关技术中通过点胶来实现显示面板和支架的定位，工艺难度高，可靠性低。
以下，以VR设备100a作为显示设备的示例，对本申请实施例提供的显示模组300作更 加详细的描述。
需要说明的是，本申请实施例的各附图中，可以定义Y轴为VR设备的长度方向，即用户佩戴VR设备时左眼至右眼的方向，Y轴的指向为从左至右，定义X轴为VR设备的厚度方向，可以视为镜腿的延伸方向，或者自显示模组300指向光学模组200的方向，X轴的指向为从后到前，定义Z轴为VR设备的高度方向，即用户佩戴VR设备时眼睛至额头的方向，Z轴的指向为从下到上。
图2为本申请一实施例提供的光学模组和显示模组的整体结构示意图，图3为本申请一实施例提供的光学模组和显示模组的分解结构示意图。参考图2和图3所示，在VR设备100a中，光学模组200可以设置在显示模组300的前侧，即面向人眼的一侧。光学模组200可以包括镜筒和设置在镜筒内的多个透镜，显示模组300可以包括支架32，支架32和镜筒可以通过胶水粘接，实现密封和固定连接。
图4为本申请一实施例提供的显示模组的爆炸结构示意图。参考图4所示，本申请实施例提供一种显示模组300，显示模组300可以包括：显示屏31、支架32和透明盖板33。
应理解，显示屏31的形状在本申请实施例中不做具体限制，显示屏31例如可以为矩形、圆角矩形、六边形、八边形等多种形状。本申请实施例中，以显示屏31为矩形作为示例，对显示屏31的结构以及与显示屏31对应的支架32和透明盖板33的结构做描述。
其中，显示屏31可以包括显示面板311和柔性电路板313，柔性电路板313可以自显示面板311的其中一边出线，支架32可以包括容置仓321和出线口323，容置仓321为凹槽形状的容置空间，用来容置显示面板311，柔性电路板313自出线口323伸出容置仓321外。
支架32用来作为显示模组300的结构件，提高整体结构强度，支架32例如可以为金属支架。作为用来容置显示屏31的容置空间，容置仓321的形状可以与显示屏31的形状相同，例如也可以设置为矩形，容置仓321具有一定的深度d1，该深度d1的尺寸不小于显示屏31的厚度，以使容置仓321可以将显示屏31容纳在内部，以实现对显示屏31的保护。
为了便于理解，假设显示面板311上无需设置柔性电路板313，则显示屏31整体可以卡设在容置仓321内，即显示屏31的外轮廓边缘(例如四条边)均可以与容置仓321的内侧壁紧密抵接或者过盈配合，以实现四边定位，此情况下，显示屏31在上下左右这四个方向上均不会发生定位误差，因此可以实现显示屏31的精确定位。
然而，实际上，由于柔性电路板313的存在，显示面板311的连接了柔性电路板313的出线边无法和容置仓321的侧壁过盈配合实现定位，仅通过剩下的三边定位的话，在出线边这个方向上的定位缺失，导致显示面板311在这个方向上存在定位误差，因此三边定位不足以实现显示屏31的精定位。
本申请实施例中，支架32上还可以设置定位筋322，定位筋322可以凸出设置在容置仓321的内侧壁上，定位筋322可以位于容置仓321的对应于出线边的相邻边上。透明盖板33可以固定连接在显示面板311的背离容置仓321的一侧，透明盖板33的对应于出线边的边缘可以与定位筋322抵接，以实现对显示屏31在出线边这个方向上的定位。对于出线边的相邻两边，透明盖板33与容置仓321的侧壁抵接实现定位，对于出线边的相对边，则可以通过透明盖板33与容置仓321的侧壁抵接实现定位，或者通过显示面板311与容置仓321的侧壁抵接实现定位。从而，整体上实现了四边定位，可以提高显示屏31的定位精度。
需要说明的是，定位筋322的数量可以为至少一个，即容置仓321的对应于出线边的相 邻两边中的任意一个上可以设置定位筋322，即可阻止透明盖板33在出线边这个方向上产生位移误差。应理解，定位筋322的数量可以为两个，即容置仓321的对应于出线边的相邻两边上均可以设置定位筋322，两侧对称的定位筋322可以使对透明盖板33的卡接更加可靠，防止透明盖板33两侧受力不均发生歪斜。
应理解，定位筋322为容置仓321内凸出一定高度形成的筋位，定位筋322可以与支架32整体通过一体成型工艺制作而成，例如通过模具制作而成。
在一种具体的实施方式中，如图中方位所示，出线口323可以开设在容置仓321的上部，即出线边为上侧边，出线边的相邻边即左侧边和右侧边，出线边的相对边为下侧边。此时，定位筋322可以凸出设置在容置仓321的左侧壁和/或右侧壁上，透明盖板33的顶边和定位筋322抵接，透明盖板33的左侧边、右侧边可以分别与容置仓321的左侧壁、右侧壁抵接，透明盖板33的下侧边和/或显示面板311的下侧边可以与容置仓321的下侧壁抵接。
本申请实施例中，透明盖板33的左右两侧超出显示面板311一段长度，在容置仓321的左侧壁和右侧壁上设置定位筋322，透明盖板33的顶边的左侧边缘和右侧边缘，与定位筋322抵接，可以实现显示屏31上侧方向的定位，左侧、右侧、下侧这三个方向的定位，则由容置仓321的三边定位。
透明盖板33和显示屏31固定连接形成一个整体，左侧、右侧、上侧的定位由透明盖板33的过盈配合实现，而下侧的定位，可以由透明盖板33的底边与容置仓321的下侧壁抵接实现，或者，可以由显示面板311的底边与容置仓321的下侧壁抵接实现，或者两者同时抵接实现。从而，整体上，可以实现显示屏31的精定位。
需要解释的是，上述“上”、“下”、“左”、“右”的方位描述，目的是为了方便理解各个部件之间的相对位置关系，而不是限定各个部件的绝对位置。例如，“柔性电路板313可以连接在显示面板311的上侧”对应的容置仓321的三边定位为左、右、下这三条边，不难理解，柔性电路板313可以连接在显示面板311的左侧、右侧或者下侧，除了柔性电路板313的出线侧，容置仓321的另外三条边用来实现对显示屏31的三边定位。
另外，本申请实施例中，透明盖板33可以通过光学胶和显示面板311贴合，以使透明盖板33不会影响到显示面板311的显示画质。图5为本申请一实施例提供的显示屏及支架的结构示意图。参考图5所示，容置仓321包括对应出线边的第一内侧壁321a、与第一内侧壁321a相邻的第二内侧壁321b以及与第一内侧壁321a相对的第三内侧壁321c，第一内侧壁321a可以为上侧壁，两个第二内侧壁321b可以分别为左侧壁和右侧壁，第三内侧壁321c可以为下侧壁。
图6为本申请一实施例提供的显示屏、支架及透明盖板的结构示意图。参考图6所示，透明盖板33包括对应出线边的第一定位边33a、与第一定位边33a相邻的第二定位边33b以及与第一定位边33a相对的第三定位边33c，第一定位边33a可以为顶边，两个第二定位边33b可以为左侧边和右侧边，第三定位边33c可以为下侧边。
继续参考图5和图6所示，显示面板311的宽度w1小于两个定位筋322之间的距离w3，定位筋322对显示面板311无定位作用。而透明盖板33的宽度w4大于显示面板311的宽度w1，透明盖板33的左右两侧相对于显示面板311伸出一段长度，透明盖板33的宽度w4大于两个定位筋322之间的距离w3，以使定位筋322对透明盖板33起到定位作用。透明盖板33的宽度w4可以大于等于容置仓321的左右两侧壁之间的距离w2，以使透明盖板33的左右两侧和容 置仓321过盈配合，实现左右两侧的定位。
透明盖板33的下侧相对于显示面板311的关系不做具体限定，当透明盖板33的下侧相对于显示面板311伸出一段长度时，透明盖板33和容置仓321的下侧壁抵接定位；当显示面板311的下侧相对于透明盖板33伸出一段长度时，显示面板311和容置仓321的下侧壁抵接定位；当透明盖板33的下侧和显示面板311平齐时，透明盖板33和显示面板311共同和容置仓321的下侧壁抵接定位。
在显示面板311的表面贴一层透明盖板33后，支架32的容置仓321的左侧、右侧和下侧的三边为长边定位，FPC出线侧则通过利用超出显示面板311的透明盖板33进行两个定位筋322的定位，在满足定位要求的同时可以保护显示面板311，减少显示面板311与支架32的碰撞。
整体上，本申请实施例中，通过增加设置透明盖板33，将透明盖板33固定在显示屏31的表面，可以利用透明盖板33改变显示屏31的最大轮廓，同时在支架32的容置仓321内设计凸出的定位筋322，使显示屏31的FPC出线侧通过透明盖板33和定位筋322的配合实现定位，剩余三边则利用显示屏31和容置仓321内侧壁的过盈配合实现定位，从而整体上实现了四边定位，达到了对显示屏31的精定位的效果。
上述本申请实施例中，柔性电路板313的出线宽度等于显示面板311的宽度。而对于柔性电路板313的出线宽度大于显示面板311的宽度的情况下，通过设置透明盖板33的宽度大于柔性电路板313的出线宽度，通过设置定位筋322，同样可以实现上述对显示屏31的精定位的效果。当然，不难理解，对于柔性电路板313的出线宽度小于显示面板311的宽度的情况，本申请实施例提供的透明盖板33和定位筋322配合实现定位的结构同样也可以适用。
图7为本申请一实施例提供的显示屏、支架、透明盖板及遮光片的结构示意图。参考图4和图7所示，显示模组300还可以包括遮光片34，遮光片34的内部设置有与显示面板311对应的视窗开口341，支架32还可以包括位于容置仓321四周的贴合平面324，容置仓321相对于贴合平面324向内凹陷，遮光片34贴合在贴合平面324和透明盖板33上。
贴合平面324为支架32的设置在容置仓321四周的裙边，该贴合平面324的外轮廓可以接近圆形，以方便与光学模组200的圆形镜筒贴合。
遮光片34可以为黑色的遮光麦拉等材料，通过胶水粘接在贴合平面324和透明盖板33上，胶水分布在视窗开口341的周圈，可以在提高粘接可靠性的同时，起到良好的密封效果。一方面，遮光片34可以遮挡非显示区域的光线，防止外部光线影响到显示面板311的显示效果；另一方面，遮光片34可以隔绝显示面板311的正面发光面和背面，避免灰尘自显示面板311的背面一侧，进入到显示面板311的正面发光面，起到良好的防尘效果。
本申请实施例中，透明盖板33还起到了为遮光片34提供贴合面积的作用。图8为本申请一实施例提供的显示模组的侧视剖面示意图。参考图8所示，透明盖板33的背离显示面板311一侧的表面可以与贴合平面324平齐，或者可以位于贴合平面324的面向容置仓321的一侧。
透明盖板33的背离显示面板311一侧的表面可以与贴合平面324平齐，有利于为遮光片34提供平整的贴合面。此时，可以认为显示面板311的厚度t1和透明盖板33的厚度t2之和等于容置仓321的深度d。透明盖板33的背离显示面板311一侧的表面也可以位于贴合平面324的面向容置仓321的一侧，此时，两表面的间距可以小于0.2mm，以便于通过调整在透明盖 板33上的胶水的厚度，来实现遮光片34的平整的贴合。此时，可以认为显示面板311的厚度t1和透明盖板33的厚度t2之和小于容置仓321的深度d。
显示屏31还可以包括芯片312，芯片312相对于显示面板311凸出设置，透明盖板33固定连接在显示面板311上，透明盖板33的厚度t2大于等于芯片312相对于显示面板311凸出的厚度t3。应理解，在未设置透明盖板33时，由于芯片312相对于显示面板311凸出设置，遮光片34贴合在贴合平面324和显示面板311上时，在芯片312处会发生鼓包，不仅影响外观的平整，而且会导致贴合不可靠，遮光和防尘的效果差。
而本申请实施例中，增加设置具有一定厚度的透明盖板33后，芯片312相对于透明盖板33不再凸出，透明盖板33和贴合平面324可以为遮光片34提供平整的贴合面，以使遮光片34的贴附可靠，提高遮光和防尘效果。
透明盖板33的厚度在本申请实施例中不做具体限制，透明盖板33的厚度较薄时，一方面，结构强度较低，导致安装时和支架32发生碰撞或挤压容易发生损坏，另一方面，可能会导致透明盖板33与贴合平面324的间距太大，导致遮光片34无法良好贴合；透明盖板34的厚度较厚时，一方面，可能会影响到成像效果，另一方面，会导致显示模组300整体的体积增大。在一种可能的实施方式中，透明盖板33的厚度处于0.6mm-1.2mm的范围内。
继续参考图4和图8所示，本申请实施例中，出线口323开设在容置仓321的底壁上，柔性电路板313自出线口323伸出容置仓321，并折弯后紧贴在容置仓321的底壁背面。柔性电路板313的末端设置有连接器314，连接器314用于和电路板连接，连接器314例如可以为BTB(Board To Board，板对板)连接器，通过扣合的方式实现电连接。
显示模组300还可以包括防尘件35，防尘件35可以覆盖出线口323，防尘件35可以包括泡棉、双面泡棉等防尘辅料。防尘件35自身具有弹性，填充在出线口323内，可以阻止灰尘进入，同时，不会对柔性电路板313造成损伤。
图9为相关技术提供的显示屏的结构示意图。参考图9所示，相关技术中，柔性电路板313直接从显示屏31的侧面伸出，占用长度空间大。此时，支架32的容置仓321的侧壁面上需要开设出线口，以使柔性电路板313伸出，并且出线口处设置泡棉来防尘的难度较高，因此，防尘的要求需要通过显示设备整机的结构防尘来实现，即对整机的防尘要求更高。
对比图9可知，本申请实施例提供的方案中，柔性电路板313不直接从侧面伸出，而是从支架32背面的出线口323伸出，一方面，柔性电路板323占用的体积小，有利于显示模组300整体的小型化设计；另一方面，便于泡棉等防尘辅料更好的贴附覆盖出线口323，例如柔性电路板323的两面均可以设置泡棉，可以提高防尘效果。并且，柔性电路板313自出线口323伸出后，180°折弯并贴合在支架32的背面，柔性电路板313的末端可以通过连接器314和电路板连接，支架32的背面为连接器314提供了支撑面，将连接器314与电路板扣合并压紧，有利于提高连接的可靠性和稳定性。
本申请实施例提供的显示模组300的装配过程可以为：首先，提供显示屏31和透明盖板33，将透明盖板33通过光学胶贴合在显示屏31的显示面板311的表面上，并使得透明盖板33的宽度方向上的两侧超出显示面板311的边缘一段长度；然后，将显示屏31安装在支架32内，将柔性电路板313自出线口323处伸出至支架32的背面，将透明盖板33卡设在容置仓321的三边及定位筋322之间；接着，将遮光片34贴合在支架32的贴合平面324和透明盖板33上，并使遮光片34的视窗开口341和显示面板311的显示区域正对设置；最后，将柔性 电路板313折弯并贴合至容置仓321的底壁背面上，通过连接器314连接至电路板。
需要补充的是，显示模组300装配完成后，可以通过点胶或者背胶的方式，将显示模组300和光学模组200粘接。胶可以分布在支架32的贴合平面324的周圈和光学模组200的镜筒周圈，以实现支架32和镜筒的密封连接，防止灰尘进入到透明盖板33的表面，或者进入到镜筒内的透镜上，影响到显示效果。
另外，需要说明的是，实际应用中，显示屏31和透明盖板33的装配，可以在生产显示屏31的工厂内预先装配完成，显示屏31的显示面板311自身，可以为基板、发光层、光学胶层、偏光层、盖板等叠层结构，显示屏31内自身的盖板厚度较薄，增加的透明盖板33，在显示屏31制作完成后，通过光学胶贴合在显示面板311的表面上，透明盖板33和显示屏31的装配定位，可以利用显示屏31生产过程中自身的定位结构来实现，在本申请实施例中不做具体阐述。
显示屏31和透明盖板33可以装配后作为一个整体出厂，提供给生产显示设备的厂家，后续显示屏31与支架32、遮光片34及光学模组200的装配，在生产显示设备的厂家中进行。
不难理解，对于不同型号和尺寸的显示屏31，可以使用相同尺寸的透明盖板33，从而，只需要制作同一个尺寸的支架32和遮光片34，即可以满足显示屏31和透明盖板33的装配。
也就是说，本申请实施例提供的显示模组，通过透明盖板和支架上的定位筋来定位，除了装配简单易操作的优势外，对不同尺寸规格的显示屏具有一定的兼容性，不同尺寸规格的显示屏可复用同一套结构，从而可以降低成本。
本申请实施例提供的显示模组和显示设备，通过增加设置盖设在显示面板上的透明盖板，并在支架的容置仓内增加设置定位筋，利用透明盖板的轮廓与容置仓和定位筋相配合，从而可以实现显示面板的精定位固定。
最后应说明的是：以上各实施例仅用以说明本申请实施例的技术方案，而非对其限制；尽管参照前述各实施例对本申请实施例进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请实施例技术方案的范围。
