以下结合附图对本发明的实施方式作进一步说明。附图中相同或类似的标号自始至终表示相同或类似的元件或具有相同或类似功能的元件。
另外，下面结合附图描述的本发明的实施方式是示例性的，仅用于解释本发明的实施方式，而不能理解为对本发明的限制。
在本发明中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。
请参阅图1及图2，本发明实施方式的一种近眼显示装置10，包括显示组件12，显示组件12包括相接的至少两个显示通道122，每个显示通道122包括目镜系统1222和显示模组1224，显示模组1224设置在目镜系统1222的物侧M，目镜系统1222包括透镜1223，透镜1223的数量大于或等于1且小于或等于5，目镜系统1222的焦距大于或等于10mm且小于或等于25mm。
本发明实施方式的近眼显示装置10，每个显示通道122的单眼的水平视场角α可大于或等于60度，显示组件12的水平视场角β可大于或等于90度，环幕显示效果较好。而且，将两个显示通道122相接形成一个显示组件12，降低了单个显示组件12的设计要求，单个显示通道122的镜片数量少，以到达近眼显示装置10在大视场的情况下轻薄化的目的。
具体地，在图1的示例中，显示组件12的数量是两个，用户观看时，每个眼睛对应一个显示组件12。显示模组1224用于显示图像，经目镜系统1222成像后，在目镜系统1222的像侧N投射影像到用户眼睛使用户看到显示模组1224所显示并经目镜系统1222成像后的图像。
本发明实施方式的近眼显示装置10，在像侧N所形成的图像的宽高比大于或等于1.85:1，图像对角线像素点数/对角线视场角>12像素/度。
每个显示组件12包括的显示通道122的数量可以是两个、三个、四个或其他任意多个。在图示的示例中，每个显示组件12包括两个显示通道122。如此，结构简单，也使得近眼显示装置10体积小，重量轻。
进一步地，在相接的两个显示通道122中，两个目镜系统1222的透镜1223可以相对于显示组件12的中心轴H是不对称的，透镜1223可以根据位置单独设计，外侧的观察角度较大，当视场角较大时，可以增加单眼外侧的视场角来增加整体近眼显示装置10的水平视场角。显示组件12的中心轴H可以理解为两个显示通道122的相接处所形成的分界线。
本发明实施方式的近眼显示装置10可应用于头戴式智能设备。在近眼显示装置10使用时，可将带有近眼显示装置10的头戴式智能设备戴在用户的头上进行交互。
在某些实施方式中，显示组件12在目镜系统1222的像侧N形成有人眼观看位置o，人眼观看位置o距目镜系统1222的距离L1小于相接的两个显示通道122的中心轴的交点P距目镜系统1222的距离L2。
如此，人眼观看位置o不在每个显示通道122的中心轴上，使用离轴方式设计，有助于使近眼显示装置10整体的轻薄化、扁平化。
在某些实施方式中，人眼观看位置o距目镜系统1222的最小距离L3大于或等于15mm且小于或等于18mm。
如此，有助于扩大视场角，并使得观看体验更好。
具体地，人眼观看位置o距目镜系统1222的最小距离可以理解为，目镜系统1222中最外侧的透镜1223的像侧面距离人眼观看位置o的最小距离。人眼观看位置o距目镜系统1222的最小距离例如可以是15mm，16mm，16.8mm，17mm，17.3mm或18mm等。当然，人眼观看位置o距目镜系统1222的最小距离不限于上述数值，也可以是15～18mm之间的其它任意值。
在某些实施方式中，显示组件12的数量为两个，两个人眼观看位置o之间的距离L4大于或等于53mm且小于或等于73mm。
如此，较好地适应人眼双眼的瞳距，使观看体验更好。
具体地，人眼的双眼的瞳孔之间的距离大于或等于53mm且小于或等于73mm，因此近眼显示装置10的两个人眼观看位置o之间的间距L4可以较好地适应大部分人使用，并使用户获得较好地观看体验。
可以理解，两个人眼观看位置o之间的距离L4可以是53mm，55mm，58.3mm，65mm，69.5mm或73mm。当然，两个人眼观看位置o之间L4的距离不限于上述数值，也可以是53～73mm之间的其它任意值。
在某些实施方式中，透镜1223为非球面塑胶透镜。
如此，采用非球面塑胶透镜，少量镜片即可实现较高的清晰度，使得近眼显示装置10体积小，重量轻。
在某些实施方式中，在相接的两个显示通道122中，两个显示模组1224之间的夹角θ小于或等于45度。
如此，有助于使用户观看到一体化的显示效果，视觉上没有明显的拼接感。
具体地，显示模组1224包括显示屏，两个显示模组1224之间的夹角θ，可以理解为，两个显示屏的显示平面之间的夹角小于或等于45度。显示屏的尺寸小于等于2英寸。如此，进一步使得近眼显示装置10轻薄化。
本发明实施方式中，两个显示模组1224之间的夹角θ为26度。
在某些实施方式中，显示组件12的中心轴H到显示组件12的边缘的距离L5小于或等于36.5mm。
如此，在显示组件12的数量是两个时，这样可以避免调整两个人眼观看位置o之间的距离L4时两个显示组件12之间发生机械干涉，使得观看体验更好。
在某些实施方式中，请参阅图3，在相接的两个显示通道122中，其中一个显示模组1224包括经对应的目镜系统1222能够成像的第一部位W1和经对应的目镜系统1222无法成像的第二部位W2，另一个显示模组1224可整体地经对应的目镜系统1222成像，另一个显示模组1224包括第三部位W3，经成像后的第三部位W3与经成像后的第一部位W1相接。
如此，人眼观察位置偏移时，仍可观察到显示组件12所要显示的完整图像。本发明实施方式中，人眼观察位置偏移±5mm以内时，仍可观察到显示组件12所要显示的完整图像。以人眼观察时的位置偏移量来确定重叠视场角度，最大化扩大拼接后的视场，确保观看效果。
具体地，人眼观察位置偏移时，相接的两个显示通道122中的，其中一显示模组1224存在部分区域显示的图像不能在像侧N成像，如图3所示，左边的显示模组1224A点右侧的第二部位W2不能在像侧N成像，因此在右边的显示模组1224中设置第三部位W3，可以理解，可通过显示控制的相关手段使第二部位W2和第三部位W3显示的内容相同，以使用户在眼睛稍微偏离人眼观看位置o时，也能看到完整的图像。第二部位W2或第三部位W3占显示模组1224的显示区域的比例大于或等于5％且小于或等于40％。
在某些实施方式中，请结合图1和图2，沿目镜系统1222的像侧N至物侧M的方向，透镜1223包括第一透镜a、第二透镜b和第三透镜c，第一透镜a和第二透镜b为正透镜，第三透镜c为负透镜。
如此，使用少量镜片而达到高画质的效果，使得近眼显示装置10整体的体积小，重量
轻。
具体地，沿目镜系统1222的像侧N至物侧M的方向，第一透镜a包括第一面和第二面，第二透镜b包括第三面和第四面，第三透镜c包括第五面和第六面。
在一个实施例中，目镜系统1222具体参数如下表：
其中，面间隔为该行所对应的面到下一行所对应的面之间的间距。例如，人眼观看位置o到第一面之间的间距为15mm，第一面到第二面之间的间距为10.2mm，以此类推。
本实施例中，在像侧N所成的图像的图像对角线像素点数/对角线视场角为40像素/度。如此，图像较为清晰。整体近眼显示装置10的水平视场角为90度。水平视场角大，可实现环幕显示。
请参阅图4，在另一个实施例中，沿目镜系统1222的像侧N至物侧M的方向，透镜1223包括第一透镜d、第二透镜e、第三透镜f和第四透镜g。其中，第一透镜d和第二透镜e为非球面塑胶镜片，第三透镜f和第四透镜g为球面玻璃镜片，第一透镜d、第二透镜e和第三透镜f为正透镜，第四透镜g为负透镜，第三透镜f与第四透镜g沿目镜系统1222的光轴相连，第三透镜f与第四透镜g可胶合形成组合透镜。沿目镜系统1222的像侧N至物侧M的方向，第一透镜d形成第一面和第二面，第二透镜e形成第三面和第四面，第三透镜f和第四透镜g形成第五面、第六面和第七面。目镜系统1222具体参数如下表：
其中，面间隔为该行所对应的面到下一行所对应的面之间的间距。例如，人眼观看位置o到第一面之间的间距为15mm，第一面到第二面之间的间距为3.01mm，以此类推。
当然，在其他实施方式中，一个目镜系统1222包括的透镜1223数量不限于3和4个，也可以是1个，2个或5个。透镜1223的参数也可以另外进行设计。
在某些实施方式中，近眼显示装置10包括陀螺仪，陀螺仪与显示模组1224连接，陀螺仪用于检测近眼显示装置10的转动角度，显示模组1224用于根据转动角度调整显示模组1224的显示内容。
如此，当用户使用近眼显示装置10时，头部转动，近眼显示装置10通过陀螺仪探测人体头部转过的角度，使显示模组1224显示的内容随人体头部的转动而变化，从而达到360度环幕显示的效果，有助于提升用户体验。
在某些实施方式中，在相接的两个显示通道122中，其中一个目镜系统1222的透镜1223与另一目镜系统1222的透镜1223通过胶合的方式相接。
如此，加工方便，生产成本低。例如，请参图2，在相接的两个显示通道122中，左边的第一透镜a和右边的第一透镜a通过胶合的方式相接。
在某些实施方式中，在相接的两个显示通道122中，其中一个目镜系统1222的透镜1223与另一目镜系统1222的透镜1223为一体结构。
如此，近眼显示装置10的整体结构更稳定，从而使得成像更稳定。例如，请参图5，在相接的两个显示通道122中，左边的透镜1223和右边的透镜1223为一体结构。
在某些实施方式中，多个显示通道122拼接，拼接方向为水平方向，或垂直方向，或水平方向和垂直方向同时拼接的阵列拼接，拼接后在所述像侧N所形成的图像的宽高比大于或等于1.85:1。
如此，在像侧所N所形成的图像更加扁平化，有助于提升观看效果，从而提升用户体验。
