具体实施方式
下面将结合本发明实施方式中的附图，对本发明实施方式中的技术方案进行清楚、完整地描述。
请参阅图1、图2及图6，所示为一种显示组件100。该显示组件100适用于一头戴显示设备(图未示)。该头戴显示设备可以为VR眼镜或智能头盔等，包括显示组件100及承载体(图未示)。其中，承载体可以为布料或软塑胶等制成的绑带或者帽子，用于将头戴显示设备固定或佩戴到用户的头上。该显示组件100包括两个显示目镜20(该标号在图中未见)、两个屈光度调节组件40以及控制器(图未示)。每一显示目镜20用于将图像信息投射到用户的左眼或右眼上，包括目镜模组21及可相对所述目镜模组21调节位移的显示屏22。该目镜模组21可将显示屏22所显示图像的光线沿预设的路径照射到出来，并射入用户的眼睛，使用户通过目镜模组21能观看到显示屏22上所显示的图像。每一屈光度调节组件40与一显示目镜20相配合，可调节目镜模组21与显示屏22之间的相对距离以调节所述显示组件100的屈光度。
本实施例中，所述目镜模组21包括多个光学镜片。所述显示屏22与所述目镜模组21同光轴设置，用于显示需呈现给用户的信息。所述显示组件100还包括一存储器60。该存储器60用于存储有不同屈光度时所述目镜模组21与显示屏22之间的位置信息。该位置信息是指目镜模组21与与该目镜模组 21相对应的显示屏22之间的相对距离。
请参阅图2，本实施例中，每一所述显示目镜20上设有一个所述屈光度调节组件40。该屈光度调节组件40包括屈光度感应器41、屈光度调节动力装置42及与所述屈光度调节动力装置42连接的屈光度调节传动件43。该屈光度调节传动件43转动地连接至所述显示屏22。所述屈光度感应器41、屈光度调节动力装置42固定于所述目镜模组21上。所述屈光度感应器41位于所述屈光度调节传动件43与所述显示屏22之间。所述屈光度感应器41与所述控制器50电连接，用于感测所述显示屏22与所述目镜模组21之间的相对距离。所述屈光度调节动力装置42驱动所述屈光度调节传动件43转动来调节目镜模组21与显示屏22之间的距离。所述屈光度调节动力装置42为微型动力装置。在本实施方式中，该屈光度调节动力装置42为一进步电机。所述屈光度调节动力装置42受控制器50的控制可以正转也可以反转；所述正转为屈光度调节动力装置42沿顺时针方向转动，所述反转为屈光度调节动力装置42沿逆时针方向转动。当所述屈光度调节动力装置42正转时，显示目镜20的屈光度变大，所述屈光度调节动力装置42反转时，显示目镜20的屈光度变小大。

在本实施方式中，用户还可通过输入装置输入一目标屈光度，即用户所希望调整到的屈光度的数值，然后控制器50根据目标屈光度控制所述屈光度调节动力装置42转动，使所述目镜模组21与显示屏22之间的相对距离与所述目标屈光度所对应的距离相对应。
本实施例中，所述显示组件100还包括支架10以及设置在支架10上的瞳距调节组件30。所述瞳距调节组件30还连接两个显示目镜20，用于调节两个显示目镜20之间的间距。两显示目镜20在轴向上成夹角地设置在支架10上。该存储器60还用于存储不同瞳距与两目镜模组21之间的不同距离之间的对应关系。当使用者通过瞳距调节组件30对显示组件100的瞳距进行调节后，该存储器60便存储有显示组件100处于该瞳距时两显示目镜20之间的相对距离；或/和当使用者通过屈光度调节组件40对显示组件100进行屈光度调节后，该存储器60便存储有显示组件100处于该屈光度时每一显示目镜20与其所对应的显示屏22之间的相对间距。
