为使本领域的技术人员更好地理解本公开的技术方案，下面结合附图对本公开提供的一种显示装置进行详细描述。
用于示范性的一个实施例提供一种显示装置，如图1所示，所述显示装置包括背板1和发电组件2，发电组件2设置在背板1上。在显示装置移动时，发电组件2能够将显示装置移动时所产生的动能转换为电能，并利用所转换的电能为该显示装置供电。
本实施例通过在背板1上设置发电组件2，相应在显示装置移动时，发电组件2能够将显示装置移动时所产生的动能转换为电能，并能够利用所转换的电能为该显示装置供电，从而可以提高显示装置的续航能力，以提高显示装置的使用时长。而且，本实施例提供的显示装置利用的是该显示装置移动时所产生的动能，从而可以减小能源的浪费，相应可以降低显示装置的使用成本。
可选地，发电组件2和背板1可拆卸连接。这样，便于对发电组件2进行更换和维修。
进一步可选地，发电组件2为多个。这样，各发电组件2可以产生更多的电能，相应可以更佳提高显示装置的续航能力。
以下结合图2和图3对发电组件2的具体结构进行详细的说明。
结合图2和图3所示，发电组件2可以包括发电机3和摆动组件4，摆动组件4与发电机3连接。在显示装置移动时，摆动组件4能够摆动，以驱动发电机3工作。
具体的，摆动组件4可以与发电机3的转子连接，当显示装置移动时，摆动组件4可以在自身重力的作用下带动发电机3的转子转动，相应可以使发电机3产生电能。
可选的，转子上设置有导电线圈，当转子转动时，导电线圈可以切割磁感线，相应磁通量发生变化，从而可以使导电线圈产生感应电动势(即电能)。
可选的，摆动组件4可以包括偏心摆陀或偏心摆轮。
结合图2和图3所示，发电组件2还可以包括传动组件5。传动组件5位于摆动组件4和发电机3之间，并分别与摆动组件4和发电机3连接，用于将摆动组件4的运动传递至发电机3。
具体的，传动组件5可以包括棘轮51和齿轮52，棘轮51与齿轮52啮合连接。摆动组件4与棘轮51的第一中心孔511连接，发电 机3与齿轮52的第二中心孔521连接。
当摆动组件4摆动时，摆动组件4可以带动棘轮51转动，棘轮51可以带动齿轮52转动，齿轮52可以驱动发电机3工作，即齿轮52的第二中心孔521与发电机3的转子连接，齿轮52可以带动发电机3的转子转动，相应可以使发电机3产生电能。
可选的，摆动组件4的轴和棘轮51的第一中心孔511可以通过键或花键连接，这样，可以提高摆动组件4和棘轮51的连接强度，以及提高摆动组件4和棘轮51连接位置的耐久度。发电机3的轴和齿轮52的第二中心孔521也可以通过键或花键连接，这样，可以提高发电机3和齿轮52的连接强度，以及提高发电机3和齿轮52连接位置的耐久度。
为提高发电组件2将动能转换为电能的效率，棘轮51的直径R1大于齿轮52的直径R2，即当棘轮51和齿轮52以相同的线速度转动时，棘轮51的角速度小于齿轮52的角速度。当摆动组件4摆动时，由于棘轮51的角速度小于齿轮52的角速度，相应摆动组件4带动棘轮51转动的角度，小于棘轮51带动齿轮52转动的角度，从而可以使发电机3的转子转动更大的角度，相应可以使发电机3产生更多的电能。
可选地，齿轮52和棘轮51的传动比为3-6。也就是说，当摆动组件4摆动时，齿轮52的角速度为棘轮51的角速度的3-6倍。这样，不但可以提高发电组件2将动能转换为电能的效率，还可以避免由于棘轮51的直径R1和齿轮52的直径R2差异较大导致的棘轮51和齿轮52之间产生啮合失效或滑齿等现象。
结合图2和图3所示，传动组件5还可以包括止动爪53。止动爪53设置在棘轮51的周边，且止动爪53的一端位于棘轮51的相邻两齿之间，以使棘轮51沿顺时针转动或沿逆时针转动。
具体的，在本申请实施例中，止动爪53的一端位于棘轮51的齿槽中。当摆动组件4带动棘轮51逆时针转动时，止动爪53可以在棘轮51的齿背上滑动；当摆动组件4带动棘轮51顺时针转动时，止动爪53可以在自身结构的作用下阻止棘轮51沿顺时针转动，使棘轮 51保持静止不动，从而当摆动组件4摆动时，棘轮51仅可以沿逆时针转动，相应齿轮52仅可以带动发电机3的转子沿顺时针转动。由于发电机3的转子仅沿一个方向(即顺时针)转动，相应发电机3所产生的电能为直流电能，因此可以提高发电组件2所产生的电能的稳定性。
需要说明的是，止动爪53限制棘轮51仅沿顺时针转动也是可行的，相应发电机3的转子仅沿逆时针转动。
还需要说明的是，背板1的材料可以为透明材料，这样，使用者可以观看到摆动组件4的摆动，以及传动组件5的转动，相应可以提高显示装置的观赏性和使用乐趣。
进一步的，所述显示装置还可以包括第一电池6，第一电池6与发电组件2连接，用于存储发电组件2所转换的电能。
具体的，当发电机3产生电能时，第一电池6可以将发电机3所产生的电能存储，并利用所存储的电能为显示装置供电。
可选的，第一电池6可以为铅酸蓄电池。
由于显示装置移动时所产生的动能较少，相应第一电池6所存储的电能较少，从而导致第一电池6无法驱动显示装置工作。进一步的，所述显示装置还可以包括用于为显示装置供电的第二电池8，第一电池6与第二电池8连接，第一电池6还用于为第二电池8充电。
具体的，第二电池8可以存储第一电池6中的电能，相应第一电池6可以提高第二电池8的续航能力，从而可以提高显示装置的使用时长。
可选的，第二电池8可以为锂电池。
进一步的，所述显示装置还可以包括控制器7，控制器7与第一电池6连接，用于当显示装置处于待机或关机状态时，控制第一电池6为第二电池8充电。第一电池6为第二电池8的充电过程容易导致第二电池8为显示装置供电的参数异常，当显示装置处于待机或关机状态时控制第一电池6为第二电池8充电，可以避免显示装置产生显示异常的不良。
可选的，控制器7可以为单片机或中央处理器。
可以理解的是，以上实施方式仅仅是为了说明本申请的原理而采用的示例性实施方式，然而本申请并不局限于此。对于本领域内的普通技术人员而言，在不脱离本申请的实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本申请的保护范围。
