【具体实施方式】
下面结合附图和实施方式，对本申请作进一步的详细描述。特别指出的是，以下实施方式仅用于说明本申请，但不对本申请的范围进行限定。同样的，以下实施方式仅为本申请的部分实施方式而非全部实施方式，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施方式，都属于本申请保护的范围。
在本文中提及“实施方式”意味着，结合实施方式描述的特定特征、结构或特性可以包含在本申请的至少一个实施方式中。在说明书中的各个位置出现该短语并不一定均是指相同的实施方式，也不是与其他实施方式互斥的独立的或备选的实施方式。本领域技术人员显式地和隐式地理解的是，本文所描述的实施方式可以与其他实施方式相结合。
随着增强现实(Augmented Reality，AR)和虚拟现实(Virtual Reality，VR)、混合现实(Mixed Reality，MR)的快速应用，近眼显示设备也得到了快速的发展。近眼显示设备可实现虚拟现实、增强现实或混合现实等显示效果。在此对近眼显设备的具体结构和实现原理进行介绍。
在实际应用中，近眼显示设备除了包括近眼显示光学系统外，必然还包括用于供电的电源模组，用于与其他终端进行信息交互的通信模组，用于对电源模组、通信模组和显示组件进行控制的处理器，用于集成设置电源模组、通信模组、显示组件和处理器等结构的电路板，以及用于固定各结构并方便用户佩戴的支架和壳体等机械结构。本实施例中不对这些结构进行特别限定。
请参阅图1，其揭露了近眼显示光学系统的结构示意图。该近眼显示光学系统100可包括发出具有虚拟图像信息的光线的显示组件10、对具有虚拟图像信息的光进行接收并在焦平面上形成虚拟图像的透镜组件20、对透过透镜组件20的光线进行部分反射的第一光学组件30、凹面与第一光学组件30的分光面相对设置且用于对第一光学组件30反射的光线进行反射并使光线透过第一光学组件30的第二光学组件40。其中，经第二光学组件40反射的光线透过第一光学组件30，并入射到人眼101。
具体地，显示组件10可以为基于LCD(Liquid Crystal Display，液晶显示装置)技术的液晶显示组件、基于OLED(Organic Electroluminesence Display，有机电激光显示)技术的有机电激光显示组件、基于LED(Quantum Dot Light Emitting Diodes，量子点发光二极管)技术的量子点发光二极管显示组件、曲面显示组件或基于LCOS(Liquid Crystal on Silicon，液晶附硅)技术的反射式矩阵液晶显示组件等。
当然，显示组件10也可以是Micro-OLED(Micro Organic Light-Emitting Diode，微型有机发光二极管)微显示器或Micro-LED(Micro Light Emitting Diode，微型发光二极管)微显示器等可发射无偏光线的微显示器。
因此近眼显示光学系统100需要在光路中对无偏光线进行偏振匹配。请参阅图2，其揭露了近眼显示光学系统100另一实施例的结构示意图。近眼显示光学系统100可在显示组件10与透镜组件20之间设置偏振转换件50。偏振转换件50可以将显示组件10发出的无偏光线转换为与后续光路匹配的特定方向线 偏振光或圆偏振光。
当然，显示组件10也可以为LCD(Liquid Crystal Display，液晶显示装置)微显示器等可发出偏振光的微显示器。图2中所示的近眼显示光学系统100可省略偏振转换件50。可以理解地，图2所示近眼显示光学系统100在省略偏振转换件50后，可以在后续光路中需要确定偏振方向时，再在相应地位置设置偏振转换件50或其他偏振转换装置或具有偏振转换功能的部件以进行后续光路的偏振匹配。
请参阅图1和图2，透镜组件20具有正屈光力。透镜组件20能够对显示组件10发出的具有虚拟图像信息的光线进行聚焦，并对显示组件10发出的具有虚拟图像信息的光线进行像差校正。透镜组件20可包括至少一个透镜。其中，透镜可为正透镜或负透镜。透镜可采用塑料或玻璃制成，其表面面型可以是球面或非球面。
可以理解地，本说明书的“具有正屈光力的～组件”表示组整体具有正屈光力。相同地“具有负屈光力的～组件”表示组整体具有负屈光力。“具有正屈光力的透镜”与“正透镜”含义相同。“具有负屈光力的透镜”与“负透镜”含义相同。“～透镜组件”并不限于包括多个透镜的结构，也可以设为仅包括1片透镜的结构。
第一光学组件30具有分光面。第一光学组件30朝向显示组件10和第二光学组件40的一侧表面为分光面。第一光学组件30的分光面接收显示组件10发出的具有虚拟图像信息的光线。第一光学组件30的分光面可透过一部分具有虚拟图像信息的光线并反射剩余具有虚拟图像信息的光线。经过第二光学组件40反射回来的剩余具有虚拟图像信息的光线可透过第一光学组件30到达人眼101。
在增强现实技术中，现实世界中形成具有真实图像信息的光线可透过第二光学组件40、第一光学组件30与剩余具有虚拟图像信息的光线一同到达人眼101，使得投影的虚拟图像可以叠加在用户感知的真实图像上。
第一光学组件30可包括一个透镜例如分光镜以及在透镜上设置的镀膜例如分光膜。这里对于分光膜的设置方式不做限定，可以采用镀膜方式设置，也可以采用粘贴方式设置。实际中，多采用镀膜方式。
分光膜位于透镜朝向显示组件10的一侧，形成第一光学组件30的分光面。这里对于透镜或分光膜的分光比不做限定。分光比即透射光线和反射光线的比例。示例的，分光比是5:5，即该透镜或分光膜能透射一半的光线、反射一半的光线。当然，透镜或分光膜的分光比还可以是其他比例，例如6:4、7:3等，这里不再列举。
在一实施例中，在近眼显示光学系统100中使用偏振光时，第一光学组件30还可以包括四分之一波片、偏振分光膜、偏振片及塑料或玻璃基板等。其中，塑料或玻璃基板位于远离透镜组件20和第二光学组件40的一侧，偏振片贴合于基板靠近透镜组件20和第二光学组件40的一侧，偏振分光膜贴合于偏振片靠近透镜组件20和第二光学组件40的一侧，四分之一波片贴合于偏振分光膜靠近透镜组件20和第二光学组件40的一侧或独立于第一光学组件30之外位于 第一光学组件30与第二光学组件40之间。
第二光学组件40采用玻璃或者塑料等材料制成。第二光学组件40可为曲面镜，具有凹面。第二光学组件40设置凹面的一侧朝向第一光学组件30，以便于将由第一光学组件30反射的剩余具有虚拟图像信息的光线反射至第一光学组件30。在增强现实技术中，现实世界中形成具有真实图像信息的光线可透过第二光学组件40、第一光学组件30与剩余具有虚拟图像信息的光线一同到达人眼101，使得投影的虚拟图像可以叠加在用户感知的真实图像上。
在一实施例中，“虚拟图像”与“真实图像”可均被称为“图像”。
在一实施例中，第二光学组件40的凹面可为球面、非球面或自由曲面等。当四分之一波片独立于第一光学组件30存在时，四分之一波片可以贴附于第二光学组件40上靠近第一光学组件30的一面(即第二光学组件40的凹面)。
在一实施例中，第二光学组件40可包括反射镜例如曲面镜。
请参阅图3，其揭露了近眼显示光学系统100的成像效果图。可见在近眼显示光学系统100进行使用过程中，其呈现的虚拟图像中，在视场的上方出现杂散光102，同样在视场的下方也出现杂散光103，杂散光102，103的出现对视觉体验产生明显的干扰，影响近眼显示光学系统100的整体体验效果。
另外，在其他实施例中，会形成视场内或视场外杂散光，进而进一步影响整体体验效果。
发明人在一系列的科学研究、实验过程中发觉显示组件10具有较大出射角度的光线。而此较大出射角度的光线的部分不参与虚拟图像的生成，却产生杂散光。
请参阅图4、图5、图6和图7，图4揭露了近眼显示光学系统100生成杂散光102的光路图，图5揭露了近眼显示光学系统100生成杂散光103的光路图，图6揭露了近眼显示光学系统100生成杂散光的光路图，图7揭露了近眼显示光学系统100生成杂散光的光路图。其中，光线104为视场外上方杂散光102对应光线路径，光线105为视场外下方杂散光103对应光线路径，光线106为视场内或视场外两侧全反射形成杂散光对应的光线路径。如图3中杂散光102的光路如图4所示，对应发生区域为透镜组件20最靠近第一光学组件30的透镜最外侧面，以及第二光学组件40的凹面形成的反射面靠近透镜组件20一侧的中部区域。如图3中杂散光103的光路如图5所示，对应发生区域为第二光学组件40的凹面形成的反射面靠近上方的两侧区域，以及第一光学组件30的下方两侧区域。对于视场内或视场外杂散光的光路如图6所示，由于显示组件10发光时出射角具有较大的出射角度，部分较大出射角度对应的光线会在透镜组件20中发生内全反射，对应发生区域为透镜组件20的透镜内表面。
可见，通过遮挡光线104，105，106可以抑制甚至消除产生的杂散光102，103和视场内、外的杂散光。
请参阅图8，其揭露了本申请一实施例中近眼显示光学系统200的结构示意图。其中，近眼显示光学系统200可包括上述实施例中发出具有虚拟图像信息的光线的显示组件10、对具有虚拟图像信息的光进行接收并在焦平面上形成虚 拟图像的透镜组件20、对透过透镜组件20的光线进行部分反射的第一光学组件30、凹面与第一光学组件30的分光面相对设置且用于对第一光学组件30反射的光线进行反射并使光线透过第一光学组件30的第二光学组件40。其中，经第二光学组件40反射的光线透过第一光学组件30，并入射到人眼101。
对于显示组件10、透镜组件20、第一光学组件30和第二光学组件40，可参阅上述实施例，在此不做赘述。
当然近眼显示光学系统200还包括设置在显示组件10和透镜组件20之间的滤光件60。滤光件60用于接收并透过具有虚拟图像信息的光线，使得具有虚拟图像信息的光线透过透镜组件20。
具体地，滤光件60位于显示组件10与透镜组件20之间，且与显示组件10存在一定距离处。可对显示组件10出射光线的出射角度进行筛选，遮挡产生杂散光的较大出射角度的光线。
可以理解地，显示组件10出射光线的出射角度可以转换为光线入射滤光片60的入射角。例如，显示组件10出射光线的出射角度等于光线入射滤光片60的入射角为90°。当然，在不同的条件下，显示组件10出射光线的出射角度与光线入射滤光片60的入射角两者的关系可以调整。
在一实施例中，滤光件60可使得出射角满足预设透射条件的光线透射，而出射角不满足预设透射条件的光线(也可被称为“第一光线”)则被滤光件60遮挡和/或吸收，无法透射通过。如图8所示光线104，105，106在经过滤光件60时，被遮挡，实际并未继续传播，因此以虚线表示。
请参阅图9和图10，图9揭露了图1所示近眼显示光学系统100呈现的虚拟图像的效果图，图10揭露了本申请图8所示近眼显示光学系统200呈现的虚拟图像的效果图。可见图9中，在视场的上方存在杂散光102，在视场的下方两侧存在杂散光103。而图10中视场整体尺寸无明显变化，在视场的上方以及下方的杂散光得到抑制，同时也抑制了因透镜组件20全反射造成的杂散光，进而提高了用户体验。
请参阅图11和图12，图11揭露了本申请图8所示实施例中滤光件60的结构示意图，图12揭露了本申请图11所示实施例中滤光件60的Ⅻ-Ⅻ截面示意图。
滤光件60可包括在第一方向上层叠设置的两个子滤光件例如第一子滤光件61和第二子滤光件62。
显示组件10发出的具有虚拟图像信息的光线可依次透过第二子滤光件62和第一子滤光件61，第一子滤光件61和第二子滤光件62配合可实现对显示组件10出射光线的出射角的筛选，可遮挡产生杂散光的具有较大出射角度的光线。
需要指出的是，此处以及下文中的术语“第一”、“第二”……等仅用于描述目的，而不能理解为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，限定有“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所述特征。
可以理解地是，对于“第一子滤光件”、“第二子滤光件”以及“子滤光件”等名称，在一些实施例中可以相互转换。例如在一实施例中，将其他实施 例中的“第一子滤光件”称为“第二子滤光件”，相应地，将其他实施例中的“第二子滤光件”称为“第一子滤光件”。
在一实施例中，第一子滤光件61和第二子滤光件62可间隔设置。即第一子滤光件61和第二子滤光件62仅在第一方向上排列设置。
请参阅图13和图14，图13揭露了本申请图12所示实施例中子滤光件的结构示意图，图14揭露了本申请图13所示实施例中子滤光件的XIV-XIV截面示意图。子滤光件例如第一子滤光件61和第二子滤光件62可包括在第二方向上交错层叠设置且相互连接的多个透明层611和多个遮光层612。其中，第一方向与第二方向垂直设置。
可一同参阅图11，在第一子滤光件61和第二子滤光件62层叠设置时，子滤光件例如第一子滤光件61中多个透明层611和多个遮光层612的交错层叠方向(即第二方向例如第一子方向)与第二子滤光件61中多个透明层611和多个遮光层612的交错层叠方向(即第二方向例如第二子方向)垂直设置。
当然在第一子滤光件61和第二子滤光件62层叠设置时，子滤光件例如第一子滤光件61中多个透明层611和多个遮光层612的交错层叠方向(即第二方向)与第二子滤光件61中多个透明层611和多个遮光层612的交错层叠方向(即第二方向)可不平行。即有夹角，即夹角大于0。
可以理解地是，对于“第一方向”、“第二方向”、“第一子方向”、“第二子方向”以及“方向”等名称，在一些实施例中可以相互转换。例如在一实施例中，将其他实施例中的“第一方向”称为“第二方向”，相应地，将其他实施例中的“第二子方向”称为“第一方向”。
请参阅图13和图14，透明层611用于透过显示组件10发出的具有虚拟图像信息的光线。
遮光层612可采用黑色材料制作，以便对照射在遮光层612上的光线进行遮挡吸收。遮光层612可用于对显示组件10出射光线的出射角度进行筛选，遮挡产生杂散光的具有较大出射角度的光线，即透明层612用于透过出射角符合预设透射条件的光线，遮光层612用于遮挡出射角不符合预设透射条件的光线。
每一个子滤光件中多个透明层611和多个遮光层612的设置可形成位于中部的第一滤光部613以及位于第一滤光部613两侧的第二滤光部614。
具体地，位于第一滤光部613内的遮光层613与第一方向平行。被遮光层613遮挡的光线与第一方向的夹角大于角度θ。其中，角度θ与近眼显示光学系统200像方F数之间的关系为：
Figure PCTCN2022075908-appb-000001
位于第二滤光部614内的遮光层612均向第一滤光部613一侧倾斜，且与第一方向成夹角α。被第二滤光部614中遮光层613遮挡的光线为与第一方向的夹角小于角度α-θ的光线以及与第一方向的夹角大于角度α+θ的光线。其中夹角α的取值范围为0-β，β为显示组件10发射的边缘视场主光线与第一方向的夹角。
