参见图1和图2，头戴式图像显示装置10包括支撑部件20、图像显示装置30、光线调节装置40、处理装置(未示出)、光学镜片60和反射单元70。
支撑部件20呈眼镜框式结构，其可用于安装头戴式图像显示装置10的其他部件，并可以用于将头戴式图像显示装置10佩戴在用户的眼睛前方。在一些实施例中，支撑部件20还可以呈头盔、遮光罩、护目镜等结构，本公开对此不做限制。
图像显示装置30用于提供图像光束IB，示例性地，图像显示装置30可以包括但不限于诸如OLED、Micro Oled、LCD显示屏或任何其他合适的显示装置。
光学镜片60和反射单元70二者均设置于图像显示装置30提供的图像光束IB向佩戴者的眼睛UE传播的路径上，其中，显示屏提供的图像光束首先被倾斜设置的光学镜片60反射至反射单元，反射单元将入射的图像光束再次反射至光学镜片60并向佩戴者的眼睛UE透射。
光线调节装置40设置于图像光束向佩戴者之外的外界物体传播的路径上，其在处理装置的控制下，可以至少部分地遮挡从头戴式显示装置10内向外界传递的图像光束。示例性地，光线调节装置可贴附于安装在眼镜框式支撑部件20的透明眼镜片上，从而可用于对 途经眼镜片向外界传播的图像光束进行至少部分地遮挡。
在一些实施例中，参见图3，光线调节装置40从上至下依次包括第一透明导电层410、液晶层420、第二透明导电层430和第一偏振片440。
在本实施例中，可以通过调整第一透明导电层410和第二透明导电层430的电信号来调节液晶层420内的液晶体的翻转角度，以调整入射至第一偏振片440的图像光束的光振动方向与第一偏振片440的偏振化方向之间的夹角，从而可以降低透过光线调节装置后的图像光束的光强，进而可以保护用户隐私。
优选地，光线调节装置40还可以具备至少一个表面保护层，其可以位于第一透明导电层410的远离液晶层420的一侧(例如图3所示的第一透明导电层410的上方)，或第一偏振片440的远离第二透明导电层430的一侧。
在一些实施例中，光线调节装置还可以包括电致变色装置，其可基于施加至其上的电压改变自身的可见光透射率。示例性地，电致变色装置包括但不限于全固态电致变色玻璃、染色液晶等。
在一些实施例中，所述图像显示装置提供的图像光束具有非偏振性，参考图2，图像显示装置10提供的非偏振性图像光束入射至倾斜设置的光学镜片后，反射出的图像光束具有了偏振性，为部分偏振光或者完全偏振光，当此部分偏振光或完全偏振光穿过反射单元70入射至光线调节装置40时，光线调节装置40可通过调节液晶层420内的液晶体的翻转角度，以调整入射至第一偏振片440的图像光束的光振动方向与第一偏振片440的偏振化方向之间的夹角，从而可以降低透过光线调节装置后的图像光束的光强，进而可以保护用户隐私。这样，在本实施例中，倾斜设置的光学镜片既能用于配合反射单元将图像光束向佩戴者的眼睛传播，其反射的具有偏振性的图像光束亦可被光线调节装置调整亮度，从而可对诸如OLED屏幕等非偏振光源提供的图像光束进行亮度调节。
在一些实施例中，反射单元70为圆弧形镜片。
参见图4，在一些实施例中，头戴式图像显示装置10还包括手动控制装置80，其设置于支撑部件用于基于用户的操作产生第一控制信号，以使所述处理装置基于所述第一控制信号控制所述光线调节装置对向外界物体传播的所述图像光束的遮挡程度。这样，用户可以通过调节手动控制装置80根据自身喜好控制光线调节装置对途经的图像光束的遮挡程度。
在一些实施例中，手动控制装置可以包括但不限于触摸控制器件、实体旋钮或者按键。 示例性地，手动控制装置80可以设置于支撑部件20上。
参见图4，在一些实施例中，头戴式图像显示装置10还包括环境光线传感器90，用于基于环境光线强度产生第二控制信号，以使所述处理装置基于所述第二控制信号控制所述光线调节装置对向外界物体传播的所述图像光束的遮挡程度。这样，头戴式图像显示装置可以自动根据外界环境光线强度来控制光线调节装置对途经的图像光束的遮挡程度。
参考图5，头戴式图像显示装置10包括处理装置50、手动控制装置80、环境光线传感器90、电源管理装置100、电源110和光线调节装置40。其中，处理装置50分别与手动控制装置80、环境光线传感器90和电源管理装置100可通信地耦合。处理装置50可以根据预设的图像光束调节算法，基于手动控制装置80和/或环境光线传感器90产生的信号，向电源管理装置100发出相应的指令，以控制施加至光线调节装置40的电信号，从而使光线调节装置至少部分地遮挡向外界物体传播的图像光束。在一些实施例中，处理装置可以包括但不限于中央处理器、图形处理器等。
在一些实施例中，所述光学镜片60上还设置有第二偏振片，第二偏振片的偏振化方向与第一偏振片440的偏振化方向相同。这样，在环境光线EL入射至佩戴者的眼镜UE的光线传播路径上，环境光线EL需要经过两个偏光片和一个液晶层。根据马吕斯定理(Malus’law)，强度为I 0的线偏振光，透过检偏片后，透射光的强度(不考虑吸收)为I＝I 0*cos 2θ，在本实施例中，因第二偏振片与第一偏振片的偏振化方向相同，θ仅取决于液晶层的翻转角度。因此，在本实例中，仅需控制液晶层中液晶的反转角度，即可精准地对入射至佩戴者眼睛的环境光强进行控制和调节，从而提升用户观看图像光束的清晰度。
在一些实施例中，处理装置50还可以根据预设的环境光线调节算法，基于手动控制装置80和/或环境光线传感器90产生的信号，来控制施加至光线调节装置40的电信号，从而使光线调节装置40可以调节入射佩戴者的眼睛的环境光强。
根据本公开的一个或多个实施例，提供了一种头戴式图像显示装置，包括：支撑部件；图像显示装置，设置于所述支撑部件上，用于提供图像光束；光学镜片和反射单元，均设置于所述图像光束向佩戴者的眼睛传播的路径上；其中，所述光学镜片相对于入射的图像光束倾斜设置；所述反射单元反射的图像光束经过所述光学镜片传播至所述佩戴者的眼睛；光线调节装置，设置于所述图像光束向外界物体传播的路径上；处理装置，用于控制所述光线调节装置至少部分地遮挡向外界物体传播的图像光束。
