具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例的附图，对本发明实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
除非另作定义，此处使用的技术术语或者科学术语应当为本发明所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
下面参考附图描述本发明实施例的显示装置及其控制电路。
显示装置可以是位于手机、平板电脑、个人数字助理、穿戴式设备等设备上，对该设备的显示进行控制装置。
为了更加清楚的说明上述描述的现有技术中显示装置的技术问题，以可折叠式的显示面板为两叠式为例，如图1A所示，该可折叠的显示面板分为第一显示区和第二显示区，当为平板模式时，如图1A所示，第一显示区和第二显示区组成同一平面显示，当为手机模式时，如图1B所示，第二显示区折叠至第一显示区背部，第一显示区提供显示服务。
然而，参见图1C左图，手机模式下，如果用户需要前置摄像头服务，则要保证控制面板是无边框或者窄边框(图中未示处窄边框)，则无法安放前置摄像头，如果安放前置摄像头，则如图1C右图所示，需要在第一显示区中安装边框，缩减了显示区的面积。
为了解决无边框(或窄边框)与摄像头等前置部件的矛盾，本发明实施例中，提出了一种显示装置，通过在壳体上，对应两个显示区的交错位置，设置前置部件，在显示面板折叠时，设置在壳体上的前置部件可以转换为朝 向前方的前置状态，在显示面板展开时，又可以转换为朝向后方的后置状态，增加了显示面板的显示可用区域，提高了资源利用率，减小了生产成本。
图2A为根据本发明第一个实施例的显示装置的结构示意图。如图2A所示，该显示装置包括可折叠的显示面板10以及支撑显示面板10的壳体20。
其中，显示面板10在折叠状态下，沿折叠轴划分为第一显示区和第二显示区，且第二显示区包括与第一显示区不重叠的非重叠部分。且如图2B所示，支撑非重叠部分的壳体20位置，设置有前置部件30。
另外，根据具体应用场景的不同，前置部件30可以设置在支撑非重叠部分的壳体20的不同位置，且前置部件30的数量可以为一个或者多个。
在实际应用中，折叠轴可以与显示面板10的任一一边平行，比如，如图2左图所示，折叠轴与显示面板10的短边平行，当然，随着显示面板制造技术的进步，折叠面板10的折叠轴也可以是任意方向的，如图3A所示，可以与显示面板任意一边都不平行，折叠轴也可以是任意形状，比如，如图3B所示，可以是波浪形等。
需要强调的是，本实施例中显示面板10分为可折叠的显示区的数量，可根据具体应用场景的不同而不同，比如，还可以为三个、四个等，为了便于说明，本实施例中主要以包含第一显示区和第二显示区两个显示区为例。
例如，在本实施例中，通过将显示面板10设置为不完全重叠的第一显示区和第二显示区后，使得设置在非重叠部分的壳体20上的前置部件30在折叠后，由后置状态变为前置状态，在第一显示区或第二显示区工作的时候提供功能服务，从而不需要在显示区中设置边框承载前置部件30的前提下，不影响前置部件30提供的功能服务。
然而，在实际应用中，有可能显示面板10的折叠方向是外折叠状态，在外折叠状态的应用场景下，如图4A所示，设立在支撑非重叠部分的壳***置的前置部件30，为当前显示区提供功能服务，当显示面板10的折叠方向是的内折叠状态时，则如图4B所示，显示出来的是非重叠部分对应的显示区，为了进一步提高用户的使用体验，可以在非重叠部分显示消息提醒、未接来电、电量信息等提示信息等，从而用户不打开显示装置即可获知相关信息。
基于以上描述，应当理解的是，本发明实施例中的前置部件30可以是摄 像头部件、指纹解锁部件、音量部件等，为了更加清楚的说明本发明实施例的显示装置的运作流程，下面以前置部件包括摄像头为例进行说明。
图5是根据本发明第二个实施例的显示装置的结构示意图，如图5左图所示，该显示装置的正面包括显示面板10、壳体20，以及如图5右图示出的背面包括摄像头31。
例如，如图5右图所示，当显示面板10的展开状态下，可以看成当前显示装置处于平板装模式，壳体20上的摄像头31为处于平板模式下的显示装置提供拍照服务。当如图6所示，显示面板10处于折叠状态下时，可以看成显示装置处于手机模式，从而为了满足手机模式下的自拍功能，如图6所示，壳体上的摄像头31从非重叠部分对应的壳体20上显示出来，变为前置状态，从而可为用户提供前置拍照服务。
然而，在实际执行过程中，显示面板10的折叠与展开，显示区发生了较大的变化，对于同一个图像，有可能在折叠后的显示面板10中显示的较为清晰，但是在展开后的显示面板10中，出现较多的噪点等，并且，两种状态下的显示面板10的功耗也不相同，比如，当显示面板10处于折叠状态下时，控制面板10处于低功耗模式，此时摄像头31应当采用耗能较低的低分辨率进行拍摄，因而，为了提供更好的功能体验，前置摄像头31需要根据当前显示面板10的状态调整采集的分辨率。
例如，在本发明的实施例中，显示面板10在折叠状态下，为了避免不必要的功耗，摄像头31采用第一分辨率成像，显示面板10在展开状态下，摄像头31采用第二分辨率成像，为了提供更好的显示效果，第一分辨率与第一显示区的分辨率匹配，第二分辨率与显示面板的分辨率匹配。
举例而言，当显示面板10在展开状态下的分辨率是2A*B时，则摄像头31采用2A*B分辨率拍照，当显示面板10在折叠状态下的分辨率是A*B时，则摄像头31采用A*B分辨率拍照。
需要强调的是，本发明实施例中的前置部件30如果是其他部件，为了更好提供功能服务，也需要根据显示面板10的显示状态进行功能的调整，在此不一一赘述。
由此，本发明实施例的显示装置，通过将可折叠的显示面板10中不同的显示区不以齐边的形式展现，使得折叠后，对应非重叠部分壳体上的后置部 件变为前置部件30，为当前显示区提供功能服务，在保证显示区的利用率的同时，不影响对应的功能服务，且展开状态下和折叠状态下的显示面板10共用前置部件，大大节约了生产成本。
需要强调的是，该原理适用于任意形式显示的非重叠部分，即除了上述实施例中描述的物理上贴合的折叠方式应用场景外，如图7所示，该非重叠部分也可以是空间上的不接触的显示方式来呈现，其实现原理类似，在此不再赘述。
综上所述，本发明实施例的显示装置，通过在壳体上，对应两个显示区的交错位置，设置前置部件，在显示面板折叠时，设置在壳体上的前置部件可以转换为朝向前方的前置状态，在显示面板展开时，又可以转换为朝向后方的后置状态，在不影响前置部件提供功能服务的同时，增加了显示面板的显示可用区域，提高了资源利用率，减小了生产成本。
为了实现上述实施例，本发明还提出了一种控制电路，该控制电路用于对上述实施例中描述的显示装置的显示进行控制。
图8是根据本发明第一个实施例的控制电路的结构示意图，如图8所示，该控制电路包括主控电路100、用于驱动显示装置第一显示区的第一驱动电路200和用于驱动显示装置第二显示区的第二驱动电路300。
参照图8，主控电路100与第一驱动电路200和第二驱动电路300电性连接，用于根据显示装置显示面板的折叠状态，控制第一驱动电路200和第二驱动电路300。
下面分别以显示面板处于折叠状态和展开状态两种应用场景下，主控电路100的控制过程，详细说明主控电路100如何根据显示装置显示面板的折叠状态，控制第一驱动电路200和第二驱动电路300。
场景一：显示面板处于折叠状态：
例如，在该应用场景下，主控电路100用于在显示面板在外折叠状态下，控制第一启动电路200驱动第一显示区进行显示，控制第二驱动电路300驱动第二显示区处于休眠状态。从而，当显示面板处于折叠状态时，控制不提供显示服务的第二显示区处于休眠状态，避免不必要的能耗。
在本发明的一个实施例中，主控电路100用于控制面板在内折叠状态下，控制第二驱动电路300在第二显示区在非重叠部分进行显示，比如显示未接 来电、电量信息、天气信息等提示消息，或者，也可以根据用户的个性化需求，显示用户指定的应用程序中的相关信息，比如显示用户指定的股票应用中的股票信息等。
例如，在本实施例中，主控电路100在显示面板处于内折叠状态时，当生成或获取到待显示的提示信息时，比如，获取到当前有未接电话，则为了使得用户在不打开显示面板的情况下即可获知相关提示信息，则将提示信息传递至第二驱动电路300，从而第二驱动电路300根据提示信息，驱动第二显示区进行显示。
场景二：显示面板处于展开状态：
例如，在该应用场景下，主控电路100在显示面板在展开状态下，控制第一驱动电路200驱动第一显示区，以及控制第二驱动电路300驱动第二显示区。从而，驱动两个显示区共同为用户提供显示服务。
基于以上描述，应当理解的是，如图9所示，本发明实施例的主控电路100还与前置部件相连，从而，在显示面板处于展开状态，主控电路100控制该前置部件处于后置工作状态，当显示面板处于折叠状态时，由于前置部件所在的非重叠部分折叠，从而前置部件变为前置状态，从而主控电路100控制前置部件处于前置工作状态。
为了更加清楚的描述，主控电路100如何根据显示面板的不同状态，控制前置部件的工作，下面以该前置部件为摄像头时，主控电路100在显示面板的不同状态对摄像头的控制为例进行说明。
其中，如图10所示，当前置部件为摄像头时，主控电路100与显示装置前置部件中的摄像头电性连接。
例如，在本发明的一个实施例中，参照图10的下部分，如果显示面板处于外折叠状态，当摄像头启动时，摄像头采集的图像信号传递至第一驱动电路200，从而第一驱动电路根据采集到的图像信号，驱动第一显示区进行显示。
在本发明的另一个实施例中，参照图10的上部分，如果显示面板处于展开状态，当摄像头启动时，主控电路100将摄像头采集的单帧图像信号中的一部分对应传递至第一驱动电路200，将图像信号中的另一部分对应传递至第二驱动电路300，从而，第一驱动电路200根据图像信号中的一部分驱动 第一显示区进行显示，第二驱动电路300，具体用于根据图像信号中的另一部分驱动第二显示区进行显示。
其中，在本示例中，需要强调的是，为了避免不必要的耗能，以及提高显示效果，摄像头采集的图像的分辨率根据显示面板的状态的不同而不同。
举例而言，参照图10，展开时显示面板的分辨率是2A*B，当主控电路100感知到显示面板发送的command信号，此时信号可以是相关传感器感知到显示面板处于外折叠状态时，主控电路100端就会将摄像头的分辨率变为A*B，因为这个摄像头可以支持两种分辨率2A*B和A*B，当启动摄像功能时，主控电路100端将从摄像头采集的A*B的数据只发给控制当前显示屏的驱动电路，被弯折到后面的驱动电路此时进入低功耗模式，从而将图像显示在显示面板中，完成此拍照过程。
应当理解的是，本发明实施例中，为了便于描述，将非重叠部分限制在第二显示区，在实际应用中，如果非重叠部分位于第一显示区，对应的操作原理也是类似的，比如，如果非重叠部分位于第一显示区，在外折叠状态下，工作的显示区是第二显示区，从而，在本实施例中，主控电路100用于在显示面板在外折叠状态下，控制第二启动电路300驱动第二显示区进行显示，控制第一驱动电路200驱动第一显示区处于休眠状态。
同样的，在本发明的一个实施例中，如果非重叠部分位于第一显示区，主控电路100用于控制面板在内折叠状态下，控制第一驱动电路200在第一显示区在非重叠部分进行显示，比如显示未接来电、电量信息等提示信息等。
综上所述，本发明实施例的控制电路，通过主控电路根据显示面板的状态控制显示区，在显示面板折叠时，根据折叠的方向，控制第一显示区或第二显示区进行显示，并控制前置部件处于前置工作状态，在显示面板展开时，前置部件转换为朝向后方的后置状态，控制第二显示区和第一显示区共同工作，并控制前置部件处于后置工作状态，由此，在增加了显示区的显示利用率的前提下，不影响前置部件的功能服务，提升了用户体验。
