交叉援引
本公开要求于2021年11月26日提交中国专利局、申请号为2021114208541、申请名称“一种眼球追踪模组及其制作方法、头戴式显示设备”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。
本公开涉及可穿戴技术，尤其涉及一种眼球追踪模组及其制作方法、头戴式显示设备。
随着科技的发展，头戴式显示设备得到了广泛的应用。现有的头戴式显示设备可供用户佩戴于头部，通过向用户眼睛发射光学信号，实现增强现实(Augmented Reality，AR)、虚拟现实(Virtual Reality，VR)和混合现实(Mix Reality，MR)等不同的效果。
眼球追踪技术可以采用光学记录法实现。光学记录法的原理是，利用红外相机记录被测试者的眼睛运动情况，即获取能够反映眼睛运动的眼部图像，从获取到的眼部图像中提取眼部特征，以建立视线的估计模型。其中，眼部特征可以包括：瞳孔位置、瞳孔形状、虹膜位置、虹膜形状、眼皮位置、眼角位置、光斑位置(或者普尔钦斑)等。光学记录法包括瞳孔-角膜反射法。瞳孔-角膜反射法的原理是，近红外光源照向眼睛，由红外相机对眼部进行拍摄，同时拍摄到光源在角膜上的反射点即光斑，由此获取到带有光斑的眼部图像。
为了实现眼球追踪，一般在头戴式设备上设置红外照明系统与图像采集系统。其中，为了在眼球旋转至不同角度时均能采到红外光斑的图片，红外照明系统一般由多个依次排列并镶嵌于头戴式设备上的红外光源组成。
由于红外照明系统的线路是不透明的，不透明的线路会遮挡用户的视野，故，当前VR/AR中线路只能布置于透镜边缘的壳体上。
当然，除了光学记录法外，眼球追踪装置还可以是MEMS微机电系统，例如包括MEMS红外扫描反射镜、红外光源、红外接收器；又或者是电容传感器，其通过眼球与电容极板之间的电容值来检测眼球运动；还可以是肌电流检测器，其通过在鼻梁、额头、耳朵或耳垂处放置电极，通过检测的肌电流信号模式来检测眼球运动。

下面结合附图和实施例对本公开作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释本公开，而非对本公开的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本公开相关的部分而非全部结构。
当前VR/AR中线路只能布置于透镜边缘的壳体上，而不能布置在透镜上。 VR/AR头盔的透镜尺寸因观看视野需求增大随之增大，从而对眼球追踪技术所用线路布局产生了限制和影响。也就是说，透镜越做越大，但是的眼睛不会增大。如果将线路布置于透镜边缘的壳体上，红外灯布置于透镜边缘的壳体上，影响眼球追踪的效果。将线路设置于透镜上，不透明的线路会遮挡用户的视野。
针对上述问题，本公开实施例提供一种眼球追踪模组，眼球追踪模组包括眼球追踪模组电路。图1为本公开实施例提供的一种眼球追踪模组电路的俯视图，图2为图1中所示眼球追踪模组电路的侧视图，参考图1和图2，眼球追踪模组包括眼球追踪模组电路，眼球追踪模组电路包括透镜10和透明导电薄膜11。透镜10为透光介质，可以采用玻璃或者塑料等材料形成。透明导电薄膜11位于透镜10的一侧的光学路径上，透过透镜10传播的光线穿过透明导电薄膜11。穿过透镜10传播的光线例如可以包括可见光和红外光中的至少一者。透明导电薄膜11包括基材12和线路13，线路13位于基材12上。基材12包括透明材料，透明材料至少对可见光具有较高的透过率，透明材料还可以对红外光具有较高的透过率，例如90％，95％或者99％的透过率。线路13的材料包括纳米线。
其中，纳米线是一种纳米尺度的线。根据组成材料的不同，金属纳米线(如：Cu，Ni，Pt，Au，Ag等)可以被用来制作超小电路，其除了具有优良的导电性之外，还具有优异的透光性、耐曲挠性，因此已逐渐替代传统ITO透明电极的材料，可设置为透明(半透明)柔性可弯折各类光学零部件制备。以纳米线、水性树脂、分散剂、助剂和溶剂水复配而成的一种环保型导电油墨，通过使用一种高粘度、低固含量的纳米线印刷膏并配合如下对应基材的印刷技术，固化制得透明(半透明)纳米线导电印刷层，最终成为眼球追踪所需的透明(半透 明)导电电路。目前使用比较广泛的是银材料制作的纳米银电路。
需要说明的是，为了清晰起见，图2中透镜10和透明导电薄膜11之间间隔设置。在一实施方式中，透明导电薄膜11可以固定于透镜10上。在另一实施方式中，透镜10和透明导电薄膜11之间还可以设置其他光学元件和/或粘接层。
本公开实施例提供一种眼球追踪模组，眼球追踪模组包括眼球追踪模组电路，眼球追踪模组电路包括眼球追踪模组包括透镜10和透明导电薄膜11。透明导电薄膜11包括基材12和线路13。线路13的材料包括纳米线，即，采用纳米线材料来形成线路13，从而使得线路13至少对于可见光具有较高的透过率，透明导电薄膜11至少对于可见光具有较高的透过率，将透明导电薄膜11设置于透镜10上，解决了透镜10上线路布局受限的问题。且由于线路13不会对可见光造成遮挡，线路13不会遮挡用户的视野，提高了用户的体验。
可以理解的是，为了实现完整的眼球追踪功能，除了眼球追踪模组电路外，眼球追踪模组还可以包括红外灯、主控单元和图像获取单元等部件。
可选地，线路13中导线的宽度小于或者等于0.01mm。可以理解的是，线路13中导线的宽度越小，则线路13中导线对光线的遮挡作用越弱，线路13中导线的宽度越大，则线路13中导线对光线的遮挡作用越强。本公开实施例中，线路13中导线的宽度小于或者等于0.01mm，以减轻线路13中导线对光线的遮挡作用，增加线路13的透过率，从而增加透明导电薄膜11的透过率。0.01mm被验证为人眼无法观察到的宽度，如果大于这个数值，则可能会被用户观察到，影响用户体验。
线路13中相邻导线之间的距离也会对线路13的透过率产生影响。通常地， 线路13中相邻导线之间的距离需要大于预设值，防止线路13中相邻导线之间距离过近，影响光线的通过。
可选地，基材12包括PVC薄膜、PI薄膜、PF薄膜和PET薄膜。其中，PVC薄膜主要成分为聚氯乙烯，是一种使用一个氯原子取代聚乙烯中的一个氢原子的高分子材料。PF薄膜即聚乙烯薄膜，是指用PF颗粒生产的薄膜。PF薄膜具有防潮性，透湿性小。PF薄膜是一种性能比较全面的包装薄膜。其透明性好，有光泽；具有良好的气密性和保香性；防潮性中等，在低温下透湿率下降。PET薄膜的机械性能优良，其强韧性是所有热塑性塑料中最好的，抗张强度和抗冲击强度比一般薄膜高得多；且挺力好，尺寸稳定，适于印刷、纸袋等二次加工。PI薄膜也称为聚酰亚胺薄膜，是世界上性能最好的薄膜类绝缘材料，由均苯四甲酸二酐(PMDA)和二胺基二苯醚(DDE)在强极性溶剂中经缩聚并流延成膜再经亚胺化而成。具有优良的耐高低温性、电气绝缘性、粘结性、耐辐射性、耐介质性，能在-269℃～280℃的温度范围内长期使用，短时可达到400℃的高温。特别适宜用作柔性印制电路板基材和各种耐高温电机电器绝缘材料。其中，PET薄膜、PI薄膜、PF薄膜和PVC薄膜可以采用辊对辊槽模具印刷、微凹版印刷或直接打印等印刷方式形成。基材12还可以包括玻璃基材，玻璃基材可以采取喷印、淋印、辊印、刮印或直接打印等印刷方式形成。
图3为本公开实施例提供的一种眼球追踪模组的侧视图，参考图3，眼球追踪模组还包括至少一个红外灯14，红外灯14位于透明导电薄膜11远离透镜10一侧，红外灯14与线路13电连接。线路13为红外灯14提供工作电压和/或工作电流，从而驱动红外灯14发射红外光，进而实现眼球追踪。其中，红外灯14可以采用传统的红外灯，或者，采用印刷方式形成的红外发光体。这种红 外发光体具有不可见性，对于用户来说体验会更加具备无感性。
基于同样的发明构思，本公开实施例还提供一种眼球追踪模组的制作方法，图4为本公开实施例提供的一种眼球追踪模组的制作方法流程图，图5-图7，图9，图11为本公开实施例提供的一种眼球追踪模组的制作过程示意图，图8为图7中所示眼球追踪模组的侧视图，图10为图9中所示眼球追踪模组的侧视图，图12为图11中所示眼球追踪模组的侧视图，参考图1-图12，该方法包括：
S101、提供基材12。
其中，基材12包括透明材料。
S102、采用纳米线将线路13印刷至基材12上，形成透明导电薄膜11。
本步骤中，例如可以通过纳米线印刷技术将线路13印刷至基材12上，线路13采用纳米线印刷至基材12上后，线路13呈透明状态。
其中，纳米线印刷技术可以包括丝印技术、移印技术、转印技术和打印技术中的至少一个。
S103、将透明导电薄膜11贴装至透镜10上。
本公开实施例提供一种眼球追踪模组的制作方法，用于形成上述实施例中的眼球追踪模组。该方法包括：提供基材12，采用纳米线将线路13印刷至基材12上，形成透明导电薄膜11，将透明导电薄膜11贴装至透镜10上。本公开实施例中，采用纳米线材料来形成线路13，从而使得线路13至少对于可见光具有较高的透过率，透明导电薄膜11至少对于可见光具有较高的透过率，将透明导电薄膜11设置于透镜10上，解决了透镜10上线路布局受限的问题。且由于线路13不会对可见光造成遮挡，线路13不会遮挡用户的视野，提高了用户的体验。
图13为本公开实施例提供的另一种眼球追踪模组的制作方法流程图，参考图1-图13，该方法包括：
S201、提供基材12。
S202、采用纳米线将线路13印刷至基材12上，形成透明导电薄膜11。
本步骤中，例如可以通过纳米线印刷技术将线路13按照拼版的方式印刷至基材12上。线路13采用纳米线印刷至基材12上后，基材12上形成多个线路13。可见，在一个基材12上，可以在同一工艺步骤中同时形成多个线路13，从而可以提高眼球追踪模组的制作效率。
S203、将透明导电薄膜11分片形成单体。
本步骤中，将上述步骤S202形成的透明导电薄膜11分片形成多个单体，分片后形成的单体(即单体透明导电薄膜)上可以包括至少一个线路13。后续步骤中对于透明导电薄膜11的操作可以为对单体的操作。
S204、将透明导电薄膜11按照透镜10的曲率进行成型。
如图8所示，在成型之前，透明导电薄膜11呈平面状。而透镜10的表面通常为曲面(对于球面透镜而言，透镜10的表面可以包括球面；对于非球面透镜而言，透镜10的表面可以包括非球面)，在一实施方式中，可以将平面状的透明导电薄膜11贴附到透镜10，通过贴附力使透明导电薄膜11在贴附的过程中发生形变。在本步骤中，如图10所示，在透明导电薄膜11贴附到透镜10之前，先按照透镜10的曲率对透明导电薄膜11进行弯曲，即，将透明导电薄膜11按照透镜10的曲率进行成型。则，在透明导电薄膜11贴附到透镜10之前，透明导电薄膜11的形状和透镜10的曲率相适配，在将透明导电薄膜11贴附到透镜10时，无需施加过大的贴附力，避免过大的贴附力对透明导电薄膜11中 的线路13以及透镜10造成损伤。
S205、将透明导电薄膜11按照透镜的形状尺寸进行裁切。
如图9所示，在裁切之前，透明导电薄膜11的形状为矩形。为了适配透镜的形状尺寸。可以将透明导电薄膜11按照透镜的形状尺寸进行裁切。形成如图11所示圆形的透明导电薄膜11。当然，图11所示的圆形的透明导电薄膜11仅为一种示例，在透镜的形状尺寸发生变化时，裁切所形成的透明导电薄膜11的形状对应发生变化。
S206、将透明导电薄膜11贴装至透镜10上。
本公开实施例提供的制作方法，在上述实施例的基础上，将透明导电薄膜11分片形成单体，将单体按照透镜10的曲率进行成型，将透明导电薄膜11按照透镜的形状尺寸进行裁切，然后再将透明导电薄膜11贴装至透镜10上。可以理解是，在其他实施方式中，还可以省略上述步骤S203、步骤S204和S205中的一者，或者，省略上述步骤S203、步骤S204和S205中的两者。
可选地，在另一实施方式中，在将透明导电薄膜11贴装至透镜10上之前，眼球追踪模组的制作方法还包括：在透明导电薄膜11设置有线路13的一侧形成与线路13电连接的至少一个红外灯14。线路13为红外灯14提供工作电压和/或工作电流，从而驱动红外灯14发射红外光，进而实现眼球追踪。
图14为本公开实施例提供的一种头戴式显示设备的示意图的头戴式显示设备，参考图14，头戴式显示设备包括透镜10、壳体22和头带23，头戴式显示设备还包括如本公开实施中所述的眼球追踪模组。由于本实施例提供的头戴式显示设备包括上述实施例中的眼球追踪模组，因此具有上述眼球追踪模组的有益效果，即，解决了透镜上线路布局受限的问题，以及实现线路不会遮挡用 户的视野，提高了用户的体验。
注意，上述仅为本公开的较佳实施例及所运用技术原理。本领域技术人员会理解，本公开不限于这里所述的特定实施例，对本领域技术人员来说能够进行各种明显的变化、重新调整、相互结合和替代而不会脱离本公开的保护范围。因此，虽然通过以上实施例对本公开进行了较为详细的说明，但是本公开不仅仅限于以上实施例，在不脱离本公开构思的情况下，还可以包括更多其他等效实施例，而本公开的范围由所附的权利要求范围决定。
本公开实施例所提供的眼球追踪模组可应用于头戴式显示设备中，通过采用纳米线材料来形成线路，从而使线路至少对于可见光具有较高的透过率，透明导电薄膜至少对于可见光具有较高的透过率，将透明导电薄膜设置于透镜10上，解决了透镜上线路布局受限的问题。而且，线路不会对可见光造成遮挡，线路不会遮挡用户的视野，提高了用户的体验。
