为了更清楚地说明本公开实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
在通过数码相框或电子画屏等显示装置进行图像显示或画面显示的过程中，针对用户对显示画面的不同需求，需要显示装置具备不同的显示性能。例如，显示装置显示的画面为艺术作品，需要满足艺术家对画面细腻程度的需求，则要求所述显示装置能够具备良好的显示效果。然而，即使显示装置所显示的画面为艺术作品，在不被艺术家品鉴或作为装饰品长期悬挂的情况下，该显示装置无需一直处于良好的显示状态，否则容易造成电能的浪费，导致该显示装置的功耗较大。
基于此，本公开一些实施例提供了一种显示装置。请参见图1和图2，该显示装置包括：层叠设置且被配置为分时显示的第一显示装置1和第二显示装置2；其中，第一显示装置1在显示状态下的显示画质高于第二显示装置2在显示状态下的显示画质，且第二显示装置2在显示状态下的功耗小于第一显示装置1在显示状态下的功耗。
上述第一显示装置1和第二显示装置2具备不同的显示性能和功耗，二者层叠设置，例如为固定连接，或是为可移动连接。二者分时显示，表现为第一显示装置1和第二显示装置2分别在不同的时段显示，且在第一显示装置1显示的情况下第二显示装置2处于非显示状态，或在第二显示装置2显示的情况下第一显示装置1处于非显示状态。此处，可以理解的是，第一显示装置1和第二显示装置2的显示画质均高于用户对画面显示画质的最低要求。
本公开一些实施例将第一显示装置1和第二显示装置2层叠设置，并使得第一显示装置1和第二显示装置2分时显示，可以方便用户根据自身在不同使用时段对显示画面的不同需求，从第一显示装置1和第二显示装置2中针对性的选取合适的显示装置进行显示。例如，当需要将显示装置作为装饰品时，采用显示画质低于第一显示装置1的第二显示装置2进行显示，并不会影响用户对显示装置的显示满意度，而且，由于第二显示装置2的功耗低于第一显示装置1，采用第二显示装置2进行显示时能够节省功耗，比如减少电能的浪费。当需要将显示装置的显 示画面作为艺术作品进行仔细欣赏时，采用显示画质高于第二显示装置2的第一显示装置1进行显示，可以满足用户(比如：艺术家)对画面细腻程度的需求，以提升用户的视觉体验。因此，本公开一些实施例提供的显示装置能够满足用户的多样化需求，有利于提升用户的使用满意度。
需要说明的是，在一些实施例中，第二显示装置2作为显示功耗和显示画质低于第一显示装置1的显示装置，第二显示装置2包括具有N种稳态的多稳态显示装置，其中，N为≥2的正整数。
多稳态显示装置能够在两种或两种以上的不同稳态进行显示；多稳态显示装置在其任一稳态显示时不需要持续电压供应，且在每两个稳态之间切换例如刷新画面时才需要供电。这也就是说，多稳态显示装置一般通过断电显示模式和通电切换模式来实现显示。如果多稳态显示装置长时间稳定在某一显示状态，其对电能的消耗就很少，有利于减小功耗，使得多稳态显示装置适合应用于不需要频繁更新显示画面的场景，比如数码相框、电子画屏或电子广告牌等。
示例性地，第二显示装置2为双稳态显示器。双稳态显示器的每个显示单元(CELL)在不施加电压的状况下就可以拥有亮态与暗态两种不同的显示状态，而且能够对应维持下去，因此被称为双稳态。双稳态显示器在不施加电压的状况下可以记忆画面并显示，从而有效降低电量耗损。在理想状态下，双稳态显示器相较于传统的液晶显示装置，可节省高达数百倍的耗电量。此外，双稳态显示器通过粒子、电介质液体或Ch-LCD(Cholesteric Liquid Crystal Display，胆甾相液晶)散射光线来显示图像，即利用周围的光线的散射来显示图像，属于非发射性的技术。它比传统显示装置中有机发光二极管(Organic Light-Emitting Diode，OLED)等发射型的显示器消耗更少的能源，因为后者需要耗费很多电能用于产生比外部环境光更亮的光线来显示具有较好可读性的图像。可见，双稳态显示器明显比传统显示装置的功耗更低
上述一些实施例采用多稳态显示装置作为第二显示装置2，可以在确保第二显示装置2具有满足要求的显示画质的前提下，实现第二显示装置2在断电显示模式和通电切换模式之间的操作，从而进一步降低第二显示装置2的功耗。
请继续参见图1和图2，在第一显示装置1和第二显示装置2层叠设置的情况下，第二显示装置2位于第一显示装置1的显示侧，或，第一显示装置1位于第二显示装置2的显示侧，均可。
可选地，在一些实施例中，第二显示装置2位于第一显示装置1的显示侧，第二显示装置2在非显示状态下透光。如此，在利用第二显示装置2显示的过程中，第一显示装置1位于第二显示装置2的非显示侧并处于非显示状态，第一显示装置1的存在不会影响第二显示装置2的显示效果。在利用第一显示装置1显示的过程中，第二显示装置2处于非显示状态并透光，第二显示装置2虽然位于第一显示装置1的显示侧，但第二显示装置2不会对第一显示装置1的显示光线造成遮挡，可以确保第一显示装置1完成其较高显示画质的显示。
典型的，第二显示装置2固定设置在第一显示装置1的显示面，其中，第一显示装置1的显示面是指第一显示装置1被配置为显示画面的表面。第二显示装置2通过粘接、铆接或螺纹连接等的连接方式与第一显示装置1固定连接，使得第二显示装置2和第一显示装置1的相对位置固定。这样仅通过切换第二显示装置2和第一显示装置1的显示状态，即可完成用户对显示装置中不同显示模式的选择使用。当然，第二显示装置2和第一显示装置1的显示状态的切换，可以人为的手动控制，也可以由控制器进行控制。
上述第一显示装置1的显示画质高于第二显示装置2的显示画质，第一显示装置1的类型可以有多种，例如液晶显示装置、有机发光二极管显示装置、等离子显示装置或量子点显示装置等。本公开一些实施例对第一显示装置1的类型不做限定，只要第一显示装置1的显示画质能 够满足艺术家对画面细腻程度的需求即可。
同理，本公开一些实施例对第二显示装置2的类型也不做限定，只要第二显示装置2的显示画质高于用户对画面显示画质的最低要求，且其功耗远远低于第一显示装置1的功耗即可。
示例性地，第二显示装置2为电致变色显示器，电致变色显示器中设置有电致变色材料。电致变色是指材料的光学属性(反射率、透过率、吸收率等)在外加电场的作用下发生稳定、可逆的颜色变化的现象，在外观上表现为颜色和透明度的可逆变化。例如，电致变色材料具有双稳态的性能，使得用电致变色材料做成的电致变色显示器不仅不需要背光灯，而且在其显示静态图像后，只要显示内容不变化，就不会耗电，能够达到节能的目的。
示例性地，第二显示装置2为电润湿式显示器。电润湿式显示器中设置有油膜染料，通过改变油膜染料内液滴与基板之间的电压，能够改变液滴在基板上的润湿性，即能够改变液滴的接触角，使液滴发生形变、位移等的现象，从而改变电润湿式显示器的显示状态。
示例性地，第二显示装置2为电泳式显示器。电泳式显示器采用电泳显示技术，即利用电压驱动有颜色的带电粒子在电泳液内移动，能够呈现不同颜色的显示效果。可选地，电泳式显示器为双稳态显示；电泳式显示器具有两种带电粒子，其中一种为白色粒子，另一种为吸光粒子，比如黑色粒子。当白色粒子聚集在显示器的显示面发出白光时，显示器处于点亮显示状态；当吸光粒子聚集在显示器的显示面吸收光线时，显示器处于不显示状态。此外，可选地，电泳式显示器具有一种带电粒子(比如白色粒子)和一种有色电介质液体。当白色粒子聚集在显示器的显示面发出白光时，显示器处于点亮显示状态；当白色粒子移动到显示器的显示面的对侧时，显示器将转换为另一种颜色，该颜色是能被使用者看到的电介质液体的颜色。
示例性地，第二显示装置2为胆固醇液晶显示器。胆固醇液晶显示 器中设置有胆固醇液晶。胆固醇液晶是一种呈螺旋状排列的特殊液晶，属于有机显示材料的一种。胆固醇液晶内通过添加不同旋转螺距的旋光剂，可以对应调配出红、绿、蓝等颜色，以满足彩色化显示的需求。由于胆固醇液晶显示技术与电泳显示技术类似，都可以具有双稳态显示的特性，亦即在画面静止时，几乎不需要用电，因此与电泳显示技术一样具备省电特性。
需要补充的是，上述几种不同类型的第二显示装置2均可实现反射显示，即能够反射环境光线而将画面显示出来，从而能够进一步降低显示装置的功耗。
此外，典型的，第二显示装置2为电子墨水显示器。像多数传统墨水一样，电子墨水和改变它颜色的线路可以打印到许多柔软材料的表面，该柔软材料例如为：可弯曲的塑料、聚脂膜、纸或布等。和传统墨水有所差异的是，电子墨水在通电时改变颜色，可以显示变化的图像，从而实现像计算器或手机中显示界面同样的显示。因此，电子墨水显示器更易于做成柔性显示装置，从而有利于实现第二显示装置2在第一显示装置1的显示侧11或其显示侧11对侧的移动，例如将第二显示装置2缠绕在卷轴上，通过卷轴的转动带动第二显示装置2在第一显示装置1的显示侧11或其显示侧11的对侧移动，如此还能够节省移动空间。
在一些实施例中，第二显示装置2采用较为轻薄的、且由电子墨水显示器或电致变色显示器等构成的柔性显示装置，更容易实现其在非显示状态下透光。
当然，在一些实施例中，如图2所示，第一显示装置1位于第二显示装置2的显示侧21，第一显示装置1在非显示状态下透光。此种情况下，第一显示装置1和第二显示装置2中二者显示状态的切换，可以参照前述一些实施例的记载内容来完成。此外，类似的，第一显示装置1固定设置在第二显示装置2的显示面，也是允许的。
在一些实施例中，请参阅图3～图7，显示装置还包括移动件3。移 动件3连接第一显示装置1和第二显示装置2，移动件3被配置为将第一显示装置1和第二显示装置2中的一个移动至另一个的显示侧或显示侧的对侧。这也就是说，第一显示装置1和第二显示装置2之间可移动连接。
本公开的一些实施例对移动件3的结构不做具体限定，以移动件3能够实现第一显示装置1和第二显示装置2之间的相对运动为准，其中，第一显示装置1和第二显示装置2之间的相对运动包括相对转动或相对平移。
可选地，第一显示装置1和第二显示装置2为非柔性显示装置，第一显示装置1和第二显示装置2之间的相对运动为相对转动。请参阅图3和图4，移动件3包括：与第一显示装置1固定连接的第一转轴31、与第二显示装置2固定连接的第二转轴32、以及与第一转轴31和第二转轴32分别可转动连接的联动块33。如此，第一显示装置1可以相对第二显示装置2发生360°翻转，反之亦然(即第二显示装置2可以相对第一显示装置1发生360°翻转)。当然，其他能够实现第一显示装置1和第二显示装置2之间360°翻转的结构，也均适用于移动件3。
在需要第一显示装置1显示的情况下，将第一显示装置1翻转至第二显示装置2的显示侧。在需要第二显示装置2显示的情况下，将第二显示装置2翻转至第一显示装置1的显示侧。当显示装置采用此种结构时，其第一显示装置1和第二显示装置2均不存在在非显示状态下透光的限制。
可选地，第一显示装置1和第二显示装置2中的至少一者为柔性显示装置，第一显示装置1和第二显示装置2之间的相对运动为相对平移。
在一些实施例中，请参见图5a和图5b、以及图6a和图6b，第一显示装置1和第二显示装置2中的其中一个为柔性显示装置，另一个为非柔性显示装置。移动件3包括与柔性显示装置传动连接的转动轴30，所述柔性显示装置的一端绕过转动轴30延伸设置在非柔性显示装置的显 示侧或显示侧的对侧。
示例性地，请参见图5a和图5b，第二显示装置2为柔性显示装置，第一显示装置1为非柔性显示装置。转动轴30位于第一显示装置1的端侧(比如图5a中所示的顶侧)，转动轴30与第一显示装置1的端部可转动连接，或不连接。转动轴30与第二显示装置2传动连接，比如摩擦传动连接或啮合传动连接等。
初始状态下，如图5a所示，第二显示装置2位于第一显示装置1的显示侧11，且第二显示装置2的一端绕过转动轴30延伸设置在第一显示装置1的显示侧11的对侧。在需要使用第一显示装置1进行显示的情况下，即需要将显示装置由低功耗显示模式切换到高画质显示模式时，逆时针转动该转动轴30，由转动轴30带动第二显示装置2位于第一显示装置1显示侧11的部分，向第一显示装置1的显示侧11的对侧移动。即，第二显示装置2位于第一显示装置1的显示侧11的部分向上移动，第二显示装置2的绕过传动轴30延伸设置在第一显示装置1的显示侧11的对侧的部分向下移动，使得第二显示装置2在转动轴30的动力传送下与第一显示装置1发生平行于其显示面的移动。
如5b所示，当第二显示装置2位于第一显示装置1的显示侧11的部分不会遮挡第一显示装置1的显示面时，停止转动转动轴30，使用第一显示装置1显示便可。
在需要使用第二显示装置2进行显示的情况下，即需要将显示装置由高画质显示模式切换到低功耗显示模式时，顺时针转动转动轴30，由转动轴30带动第二显示装置2位于第一显示装置1的显示侧11的对侧的部分向第一显示装置1的显示侧11移动，直至第二显示装置2位于第一显示装置1的显示侧11的部分覆盖了第一显示装置1的显示面，使用第二显示装置2显示便可。
示例性地，请参见图6a和图6b，第二显示装置2为非柔性显示装置，第一显示装置1为柔性显示装置。转动轴30位于第二显示装置2的 端侧(比如图6a中所示的顶侧)，转动轴30与第二显示装置2的端部可转动连接，或不连接。转动轴30与第一显示装置1传动连接，比如摩擦传动连接或啮合传动连接等。
初始状态下，如图6a所示，第一显示装置1位于第二显示装置2的显示侧21的对侧，且第一显示装置1的一端绕过传动轴30延伸设置在第二显示装置2的显示侧21。在需要使用第一显示装置1进行显示的情况下，即需要将显示装置由低功耗显示模式切换到高画质显示模式时，顺时针转动传动轴30，由转动轴30带动第一显示装置1位于第二显示装置2的显示侧11的对侧的部分，向第二显示装置2的显示侧21移动。即，第一显示装置1的绕过传动轴30延伸设置在第二显示装置2的显示侧21的部分向下移动，第一显示装置1设置在第二显示装置2的显示侧21对侧的部分向上移动，使得第一显示装置1在转动轴30的动力传送下与第二显示装置2发生平行于其显示面的移动。
如6b所示，当第一显示装置1位于第二显示装置2显示侧21的部分覆盖了第一显示装置1的显示面时，停止转动转动轴30，使用第一显示装置1显示便可。
在需要使用第二显示装置2进行显示的情况下，逆时针转动转动轴30，由转动轴30带动第一显示装置1位于第二显示装置2的显示侧21的部分向第二显示装置2的显示侧21的对侧移动，直至第一显示装置1位于第二显示装置2的显示侧的部分不会遮挡第二显示装置2的显示面，使用第二显示装置2显示便可。
在上述一些实施例中，通过转动轴30的往复转动，能够带动柔性显示装置移动至非柔性显示装置的显示侧或其显示侧的对侧，从而实现显示装置在低功耗显示模式和高画质显示模式之间的切换。这样所需的移动空间较小，即能够利用高画质显示模式满足艺术家对画面细腻程度的需求，又能够利用低功耗显示模式在能耗较低的情况下达到装饰品的装饰效果，从而满足用户的多样化需求。
此外，在一些实施例中，第一显示装置1和第二显示装置2之间的相对平移，也可以通过其他的方式实现。例如，第二显示装置2为柔性显示装置，第二显示装置2的至少两端分别安装有支撑杆，通过各支撑杆在水平方向或垂直方向的运动，可以带动第二显示装置2在第一显示装置1的显示侧或其显示侧的对侧移动。
当然，在一些实施例中，第一显示装置1和第二显示装置2均为柔性显示装置，第一显示装置1和第二显示装置2之间的相对运动为相对平移，移动件3包括与其中一个柔性显示装置传动连接的转动轴30；其中，与转动轴30传动连接的柔性显示装置的一端绕过转动轴30，且延伸设置在另一个柔性显示装置的显示侧或其显示侧的对侧。如此，通过转动轴30的往复转动，能够带动与转动轴30传动连接的柔性显示装置移动至另一个柔性显示装置的显示侧或其显示侧的对侧，从而实现显示装置在低功耗显示模式和高画质显示模式之间的切换。
在一些实施例中，请参阅图7，显示装置还包括驱动件4。驱动件4与移动件3连接，驱动件4被配置为驱动移动件3对第一显示装置1或第二显示装置2进行移动。
可选地，请继续参阅图7，移动件3为转动轴30，驱动件4采用电机(例如步进电机)。驱动件4驱动移动件3转动，利用移动件3带动与其传动连接的第一显示装置1移动。
在一些实施例中，请继续参阅图7，显示装置还包括控制器5。控制器5分别与第一显示装置1、第二显示装置2和驱动件电连接；控制器被配置为控制第一显示装置1和第二显示装置2分时显示，以及控制驱动件4驱动移动件3动作。
典型的，显示装置还包括电子感应器6。电子感应器6与控制器5电连接；电子感应器6被配置为感应人体信息，以根据其感应到的人体信息向控制器5发送感应信号；控制器5还被配置为根据电子感应器6发送的感应信号对第一显示装置1、第二显示装置2和驱动件4进行控 制。
可选地，电子感应器6采用人体红外感应器或人体接触式感应器。电子感应器6在持续感应到人体信息一段时间后，才根据其感应到的人体信息向控制器5发送感应信号。用于示范的，电子感应器6持续感应到人体信息的一段时间为10s(秒)，本公开一些实施例对此不作具体限定。
电子感应器6通过判断其感应到的人体信息的持续时间是否大于预设时长，可以甄别出对应的人体只是路过显示装置所在的区域，还是在观看显示装置所显示的画面，从而确定是否需要输出感应信号至控制器5，以由控制器5控制对应的第一显示装置或第二显示装置完成显示模式的切换。
例如，预设时长为10s。若电子感应器6持续感应到人体信息的时长不足10s，则表示人体只是路过显示装置所在的区域，电子感应器6无需向控制器5发送感应信号，控制器5可以控制第二显示装置2完成低功耗显示模式的显示。若电子感应器6持续感应到人体信息的时长大于10s，则表示人体正在显示装置前停留，以对显示装置显示的画面进行仔细观看，电子感应器6需要向控制器5发送感应信号，以使控制器5控制第一显示装置1完成高画质显示模式的显示。这样一来，本公开一些实施例提供的显示装置，不仅能够实现显示装置的自动化控制，而且还避免了低功耗显示模式和高画质显示模式之间不必要的刷新，以减小显示装置的电损耗。
在上述实施方式的描述中，具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
