具体实施方式
实施例一
图1为实施例一提供的一种显示装置的结构示意图，本实施例可适用于满足用户的显示需求的同时，灵活的对显示屏进行控制的情况，如图1所示，该显示装置包括：显示屏101以及至少两个控制器102；
所述至少两个控制器102中运行有不同类型的操作***，且不同类型操作***具有不同的功耗；
所述至少两个控制器102分别使用不同类型的接口与所述显示屏101相连接，至少两个控制器102设置为在各自的工作状态下，控制显示屏101进行显示。
其中，不同控制器102中运行有不同类型的操作***，且不同类型操作***具有不同的功耗。可选的，操作***包括：Android操作***和实时操作***(Real Time Operating System，RTOS)操作***。其中，RTOS操作***的功耗小于Android操作***。运行RTOS操作***的控制器102的功耗小于运行Android操作***的控制器102。

其中，所述至少两个控制器102在各自的工作状态下，控制显示屏101进行显示。所述至少两个控制器102的状态包括工作状态和休眠状态。所述至少两个控制器102根据显示装置的需求切换状态，控制显示屏101进行显示。在一实施例中，运行有较高功耗操作***的控制器102在由工作状态切换至休眠状态时，断开自身对显示屏101的显示控制，同时运行有较低功耗操作***的控制器102从休眠状态切换至工作状态，开启自身对显示屏101的显示控制；运行有较高功耗操作***的控制器102在由休眠状态切换至工作状态时，建立自身对显示屏101的显示控制，同时运行有较低功耗操作***的控制器102从工作状态切换至休眠状态，断开自身对显示屏101的显示控制。根据显示装置的需求，对多个控制器102的状态进行切换，运行有高功耗操作***的控制器102不会一直处于工作状态，从而减少了电池电量消耗大量，延长显示装置的待机时间。
可选的，显示屏101包括：有机发光显示面板，以及覆盖于有机发光显示面板上的触摸屏。
其中，通过多个控制器102在各自的工作状态下，控制有机发光显示面板，以及覆盖于有机发光显示面板上的触摸屏进行显示。
在一实施例中，所述触摸屏，设置为获取触摸位置信息，并将所述触摸位置信息发送至一个特定的控制器(例如，主控制器)或者发送至当前处理工作状态的控制器等。通过设置触摸屏，可以实现用户与显示装置的交互，使用户操作显示装置更加便捷。
