具体实施方式
为了能够更清楚地理解本公开的上述目的、特征和优点，下面将对本公开的方案进行进一步描述。需要说明的是，在不冲突的情况下，本公开的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本公开，但本公开还可以采用其他不同于在此描述的方式来实施；显然，说明书中的实施例只是本公开的一部分实施例，而不是全部的实施例。
图1为本公开实施例提供的一种多层显示面板的结构示意图，如图1所示，多层显示面板10包括第一显示模块100，第一显示模块100包括：第一显示层110、第二显示层120和第三显示层130。
其中，第一显示层110的第一出光面正对第二显示层120，第一显示层110的第二出光面正对第三显示层130，第一出光面与第二出光面相对设置。
第一显示层110包括：阵列分布的多个第一像素单元111，每个第一像素单元111中包括多个第一子像素单元1111。第二显示层120包括：第一遮光单元121和第一显示粒子122，第一遮光单元121正对相邻第一子像素单元1111之间的区域，第一显示粒子122位于相邻第一遮光单元121之间的区域。第三显示层130包括：第二遮光单元131和第二显示粒子132，第二遮光单元131正对相邻第一子像素单元1111之间的区域，第二显示粒子132位于相邻第二遮光单元131之间的区域。
第一显示层110、第二显示层120和第三显示层130，均用于显示图像。
示例性的，如图1所示，第一像素单元111沿X方向和Y方向阵列分布，每个第一像素单元111可以包括三个第一子像素单元1111，分别为红色子像素单元、绿色子像素单元和蓝色子像素单元，每个第一像素单元111也可以包括四个第一子像素单元1111，分别为红色子像素单元、绿色子像素单元、蓝色子像素单元和白色子像素单元。本实施例中，对于第一子像素单元的种类不做具体限制。
相邻第一子像素单元1111之间存在一定的间隙，在该间隙内设置有金属走线，这些金属走线用于电连接对应的第一子像素单元1111和驱动电路，使得驱动电路可以控制第一子像素单元1111发光。第一子像素单元1111位于第一显示层110的显示区内，即金属走线位于显示区内，当外界环境光照射至第一显示层110内时，金属走线能够反射外界环境光，且反射的外界环境光通过第一显示层110的出光面射出，导致第一显示层110出射的外界环境光的强度较高，用户观看时出现眩光问题。
示例性的，第二显示层120中的第一遮光单元121，可以是沿X方向延伸沿Y方向排列的遮光条，和/或沿Y方向延伸沿X方向排列的遮光条，还可以是沿X方向和Y方向排列的遮光块，本实施例对第一遮光单元的具体形态和颜色不做具体限制。第一遮光单元121之间的区域填充有第一显示粒子122，第一显示粒子122包括白色显示粒子和黑色显示粒子，白色显示粒子可以反射光束，故而显示白色，黑色显示粒子可以吸收光束，故而显示黑色。如此通过白色显示粒子和黑色显示粒子，第二显示层120可以显示黑白图像。
第二显示层120正对第一显示层110的第一出光面，第一遮光单元121正对相邻第一子像素单元1111之间的区域，由此，第一遮光单元121能够覆盖第一显示层110内的金属走线。若通过第一显示层110的第一出光面显示图像，第一子像素单元1111发射的光束通过相邻第一遮光单元121之间的区域射出，如图1所示(实线箭头表示第一遮光单元发射的光束)，也就是说第一遮光单元121不会遮挡第一子像素单元1111发射的光束，从而避免第二显示层120对第一显示层110的显示效果造成影响。同时，外界环境光也会通过第一出光面照射至第一显示层110的内部，在外界环境光入射至第一显示层110的内部之前，第一遮光单元121会遮挡部分外界环境光，如图1所示(虚线箭头表示外界环境光)，从而降低入射至第一显示层110内部的光线强度。而入射至第一显示层110内部的外界环境光，部分会被金属走线反射，第一遮光单元121能够阻挡部分反射光从第一显示层110的第一出光面射出，进一步降低了第一显示层110从第一出光面射出的外界环境光的强度。
第三显示层130正对第一显示层110的第二出光面，第三显示层130中的第二遮光单元131与第一遮光单元121的结构和功能类似，第三显示层130中的第二显示粒子132与第一显示粒子122的结构和功能类似，详见第一遮光单元121和第一显示粒子122的描述。同理，第二遮光单元131不会遮挡第一子像素单元1111发射的光束，从而避免第三显示层130对第一显示层110的第二出光面的显示效果造成影响；同时，第二遮光单元131会遮挡部分外界环境光，从而降低入射至第一显示层110内部的光线强度，第二遮光单元131还能够阻挡部分反射光从第一显示层110的第二出光面射出，进一步降低了第一显示层110从第二出光面射出的外界环境光的强度。
通过第二显示层120和第三显示层130显示图像，可以实现多层显示面板的双面显示，同时，在第一显示层110显示图像时，第二显示层120和第三显示层130不对第一显示层110的显示效果造成影响。此外，第二显示层120和第三显示层130可以遮挡部分外界环境光，降低入射至第一显示层内部的外界环境光的强度，进而能够降低第一显示层射出的 外界环境光的强度。而且，遮光单元还能够遮挡第一显示层内金属走线反射的外界环境光，进一步降低第一显示层射出的外界环境光的强度，从而能够解决眩光问题。
本实施例中，第一显示模块包括：第一显示层、第二显示层和第三显示层，第一显示层的第一出光面正对第二显示层，第一显示层的第二出光面正对第三显示层，第一出光面与第二出光面相对设置；第一显示层包括：阵列分布的多个第一像素单元，每个第一像素单元中包括多个第一子像素单元，第二显示层包括：第一遮光单元和第一显示粒子，第一遮光单元正对相邻第一子像素单元之间的区域，第一显示粒子位于相邻第一遮光单元之间的区域；第三显示层包括：第二遮光单元和第二显示粒子，第二遮光单元正对相邻第二子像素单元之间的区域，第二显示粒子位于相邻第二遮光单元之间的区域，第一显示层、第二显示层和第三显示层均可以显示图像，如此，即可以通过第二显示层显示图像也可以通过第三显示层显示图像，从而能够实现双面显示。另外，由于遮光单元位于相邻第一子像素单元之间，因此遮光单元不会对第一子像素单元射出的光束造成遮挡，避免对第一显示层的显示质量造成影响，遮光单元能够遮挡部分外界环境光，降低入射至第一显示层内部的外界环境光的强度，即能够降低第一显示层射出的外界环境光的强度。同时，遮光单元还能够遮挡第一显示层内金属走线反射的外界环境光，进一步降低第一显示层射出的外界环境光的强度，从而能够解决眩光问题。
可选的，图2为本公开实施例提供的一种工作模式下的多层显示面板的结构示意图，图3为本公开实施例提供的另一种工作模式下的多层显示面板的结构示意图。结合图1-图3所示，第一显示层110，用于在第一工作模式下通过第一出光面显示图像，在第二工作模式下向第二显示层120提供背光，在第三工作模式下通过第二出光面显示图像，在第四工作模式下向第三显示层130提供背光。

若多层显示面板10处于第一工作模式，第一显示层110中的第一像素单元111发射的光束通过第一出光面射出，并穿过第二显示层120中相邻第一遮光单元121之间的区域，如图1所示。如此，第一显示层110通过第一出光面可以显示彩色图像。
若多层显示面板10处于第二工作模式，第一显示粒子122分布于相邻第一遮光单元121之间区域，第一显示层110中的第一像素单元111发射的光束照射至位于相邻第一遮光单元121之间区域的第一显示粒子122，第一显示粒子122中的一部分可以吸收第一像 素单元111发射的光束，另一部分可以反射第一像素单元111发射的光束，如图2所示。如此，第二显示层120以第一显示层110发射的光束作为背光，可以在较暗的环境下显示黑白图像。
若多层显示面板10处于第三工作模式，第一显示层110中的第一像素单元111发射的光束通过第二出光面射出，并穿过第三显示层130中相邻第二遮光单元131之间的区域，如图1所示。如此，第一显示层110通过第二出光面可以显示彩色图像。
若多层显示面板10处于第四工作模式，第二显示粒子132分布于相邻第二遮光单元131之间区域，第一显示层110中的第一像素单元111发射的光束能够照射位于相邻第二遮光单元131之间区域的第二显示粒子132，第二显示粒子132中的一部分可以吸收第一像素单元111发射的光束，另一部分可以反射第一像素单元111发射的光束，如图2所示。如此，第三显示层130以第一显示层110发射的光束作为背光，可以在较暗的环境下显示黑白图像。
若多层显示面板10处于第五工作模式，第一显示层110可以停止工作，而第二显示层120中的第一显示粒子122分布于相邻第一遮光单元121之间区域，一部分第一显示粒子122可以吸收外界环境光，另一部分第一显示粒子122可以反射外界环境光，如图3所示。如此，第二显示层120可以在外界环境光的照射下显示黑白图像。
若多层显示面板10处于第六工作模式，第一显示层110可以停止工作，而第三显示层130中的第二显示粒子132分布于相邻第二遮光单元131之间区域，一部分第二显示粒子132可以吸收外界环境光，另一部分第二显示粒子132可以反射外界环境光，如图3所示。如此，第三显示层130可以在外界环境光的照射下显示黑白图像。
本实施例中，多层显示面板在不同的工作模式下，既可以通过第一显示层双侧显示彩色图像，又可以通过第二显示层和第三显示层双侧显示黑白图像，还可以在较暗的环境下，以第一显示层发射的光束作为背光通过第二显示层和第三显示层双侧显示黑白图像，使得多层显示面板能够适用于多种显示场景，提升多层显示面板显示的多样性，还能够降低多层显示面板的能耗。
可选的，图4为本公开实施例提供的第一状态下的多层显示面板的结构示意图，图5为本公开实施例提供的第二状态下的多层显示面板的结构示意图，结合图4和图5所示，多层显示面板10还包括：第二显示模块200，第二显示模块200与第一显示模块100连接。
第一状态下，第一显示模块100叠放于第二显示模块200的出光侧，如图4所示；第 二状态下，第一显示模块100与第二显示模块200位于同一平面，如图5所示。
第一显示模块100，用于在第一状态和第二状态下显示图像。第二显示模块200，用于在第二状态下显示图像。
示例性的，第一状态可以是折叠状态，第二状态可以是展开状态，如图4所示，多层显示面板10处于折叠状态时，第一显示模块100叠放于第二显示模块200的出光侧，此时，第一显示模块100覆盖第二显示模块200，第二显示模块200的出光面可以正对第三显示层130，也可以正对第二显示层120，本实施例对此不做具体限制。
若折叠状态下第二显示模块200的出光面正对第三显示层130，如图4所示，第一显示模块100中的第一显示层110或第二显示层120可以显示图像，第三显示层130和第二显示模块200不显示图像。若折叠状态下第二显示模块200的出光面正对第二显示层120，第一显示模块100中的第三显示层130或第一显示层110可以显示图像，第二显示层120和第二显示模块200不显示图像。
多层显示面板10处于展开状态时，如图5所示，第一显示模块100与第二显示模块200位于同一平面内，此时，露出第二显示模块200的出光面，因此，第二显示模块200可以用于显示图像。若折叠状态下第二显示模块200的出光面正对第三显示层130，相应的展开状态下，露出第三显示层130的出光面，如图5所示，可以通过第二显示模块200和/或第三显示层130显示图像，或者，可以通过第二显示模块200和第一显示层110显示图像，或者，还可以通过第一显示层110显示图像。
综上所述，多层显示面板10在折叠状态下，通过第一显示模块100显示图像，在展开状态下，可以通过第二显示模块200显示图像，也可以通过第一显示模块100和第二显示模块200显示图像。
本实施例中，通过第二显示模块与第一显示模块连接，第一状态下，第一显示模块叠放于第二显示模块的出光侧，此时，第一显示模块可以显示图像，第二状态下，第一显示模块与第二显示模块位于同一平面，此时，第一显示模块与第二显示模块均能够显示图像，使得多层显示面板在多种状态下均可以显示图像，提升多层显示面板显示的多样性。
可选的，图6为本公开实施例提供的一种工作模式下的第二显示模块的结构示意图，图7为本公开实施例提供的另一种工作模式下的第二显示模块的结构示意图，图8为本公开实施例提供的又一种工作模式下的第二显示模块的结构示意图。结合图6-图8所示，第二显示模块200包括：第四显示层210和第五显示层220，第五显示层220叠放于第四显 示层210的出光侧。
其中，第四显示层210包括：包括阵列分布的多个第二像素单元211，每个第二像素单元211中包括多个第二子像素单元2111。
第五显示层220包括：第三遮光单元221和第三显示粒子222，第三遮光单元221正对相邻第二子像素单元2111之间的区域，第三显示粒子222位于相邻第三遮光单元221之间的区域。
第四显示层210，用于在第七工作模式下显示图像，在第八工作模式下向第五显示层220提供背光。第五显示层220，用于在第八工作模式和第九工作模式下显示图像。
若多层显示面板10处于第七工作模式，第四显示层210中的第二像素单元211发射的光束穿过第五显示层220中相邻第三遮光单元221之间的区域，如图6所示。如此，第四显示层210可以显示彩色图像。
若多层显示面板10处于第八工作模式，第三显示粒子222分布于相邻第三遮光单元221之间区域，第四显示层210中的第二像素单元211发射的光束照射至位于相邻第三遮光单元221之间区域的第三显示粒子222，第三显示粒子222中的一部分可以吸收第二像素单元211发射的光束，另一部分可以反射第二像素单元211发射的光束，如图7所示。如此，第五显示层220以第四显示层210发射的光束作为背光，可以在较暗的环境下显示黑白图像。

示例性的，若多层显示面板处于第二工作模式，控制第一显示层通过第一出光面射出光束，控制第二显示层中的第一显示粒子分布于相邻第一遮光单元之间的区域，使得第一出光面射出的光束照射至第一显示粒子，第一显示粒子中的白色显示粒子可以反射背光，第一显示粒子中的黑色显示粒子可以吸收背光，从而能够显示黑白图像。因此，第二显示层以第一显示层发射的光束作为背光，可以在较暗的环境下显示黑白图像。
S1033，若所述工作模式为第三工作模式，控制所述第一显示层通过第二出光面显示图像。
示例性的，若多层显示面板处于第三工作模式，控制第一显示层通过第二出光面射出光束，控制第三显示层中的第二显示粒子分布于第二遮光单元附近的区域，使得光束可以透过相邻第二遮光单元之间的区域，且透过第三显示层的光束用于显示图像，如此，第一显示层通过第二出光面可以显示彩色图像。

示例性的，若多层显示面板处于第四工作模式，控制第一显示层通过第二出光面射出光束，控制第三显示层中的第二显示粒子分布于相邻第二遮光单元之间的区域，使得第二 出光面射出的光束照射至第二显示粒子，第二显示粒子中的白色显示粒子可以反射背光，第二显示粒子中的黑色显示粒子可以吸收背光，从而能够显示黑白图像。因此，第三显示层以第一显示层发射的光束作为背光，可以在较暗的环境下显示黑白图像。
S1035，若所述工作模式为第五工作模式，控制所述第二显示层显示图像。
示例性的，若多层显示面板处于第五工作模式，控制第一显示层停止工作，控制第二显示层中的第一显示粒子分布于相邻第一遮光单元之间的区域，第一显示粒子中的黑色粒子可以吸收外界环境光，第一显示粒子中的白色粒子可以反射外界环境光，如此，第二显示层可以在外界环境光的照射下显示黑白图像。
S1036，若所述工作模式为第六工作模式，控制所述第三显示层显示图像。
示例性的，若多层显示面板处于第六工作模式，控制第一显示层停止工作，控制第三显示层中的第二显示粒子分布于相邻第二遮光单元之间的区域，第二显示粒子中的黑色粒子可以吸收外界环境光，第二显示粒子中的白色粒子可以反射外界环境光，如此，第三显示层可以在外界环境光的照射下显示黑白图像。
本实施例中，通过获取多层显示面板的工作模式；根据工作模式，控制第一显示层、第二显示层或第三显示层显示图像，如此，多层显示面板在不同的工作模式下，既可以通过第一显示层双侧显示彩色图像，又可以通过第二显示层和第三显示层双侧显示黑白图像，还可以在较暗的环境下，以第一显示层发射的光束作为背光通过第二显示层和第三显示层双侧显示黑白图像，使得多层显示面板能够适用于多种显示场景，提升多层显示面板显示的多样性，还能够降低多层显示面板的能耗。

在此基础上，继续如图13所示，多层显示面板的控制方法还包括：
S104，若所述多层显示面板处于所述第二状态，根据所述工作模式，控制所述第二显示模块显示图像。
若多层显示面板处于展开状态，露出第三显示层的出光面的同时，还露出第二显示模块的出光面，如图5所示，可以根据工作模式，控制第二显示模块是否显示图像。
需要说明的是，多层显示面板可以同时工作于多个工作模式，第二显示模块是否显示图像，与第一显示模块是否显示图像以及第一显示模块具体显示的方式无关。本实施例仅示例性展示了S104于S202之后执行，在实际应用中，S104和S202可以同时执行。
本实施例中，通过若多层显示面板处于第一状态，根据工作模式，控制第一显示层或所述第二显示层显示图像；若多层显示面板处于第二状态，根据所述工作模式，控制第二显示层或所述第三显示层显示图像，控制第二显示模块显示图像，使得多层显示面板在多种状态下均可以显示图像，提升多层显示面板显示的多样性。
图14为本公开实施例提供的又一种多层显示面板的控制方法的流程示意图，图14为图13所示实施例的基础上，执行S104时的一种可能的实现方式的具体描述，如下：
S1041，若所述工作模式为第七工作模式，控制所述第四显示层显示图像。
示例性的，如图6-图8所示，第二显示模块200包括：第四显示层210和第五显示层220，第五显示层220叠放于第四显示层210的出光侧。
在多层显示面板处于展开状态下，若多层显示面板处于第七工作模式，控制第四显示层射出光束，控制第五显示层中的第三显示粒子分布于第三遮光单元附近的区域，使得光束可以透过相邻第三遮光单元之间的区域，且透过第五显示层的光束用于显示图像，如此，第四显示层可以显示彩色图像。
S1042，若所述工作模式为第八工作模式，控制所述第四显示层向所述第五显示层提供背光，所述第五显示层显示图像。
在多层显示面板处于展开状态下，若多层显示面板处于第八工作模式，控制第四显示层射出光束，控制第五显示层中的第三显示粒子分布于相邻第三遮光单元之间的区域，使得第四显示层射出的光束照射至第三显示粒子，第三显示粒子中的白色显示粒子可以反射背光，第三显示粒子中的黑色显示粒子可以吸收背光，从而能够显示黑白图像。因此，第五显示层以第四显示层发射的光束作为背光，可以在较暗的环境下显示黑白图像。
S1043，若所述工作模式为第九工作模式，控制所述第五显示层显示图像。
在多层显示面板处于展开状态下，若多层显示面板处于第九工作模式，控制第四显示层停止工作，控制第五显示层中的第三显示粒子分布于相邻第三遮光单元之间的区域，第三显示粒子中的白色显示粒子可以反射背光，第三显示粒子中的黑色显示粒子可以吸收背光，如此，第五显示层可以在外界环境光的照射下显示黑白图像。
本实施例中，通过多层显示面板在展开状态下，若第二显示模块工作模式为第七工作模式，控制第四显示层显示图像，若第二显示模块工作模式为第八工作模式，控制第四显示层向第五显示层提供背光，第五显示层显示图像，若第二显示模块工作模式为第九工作模式，控制第五显示层显示图像，扩展了第二显示模块显示的方式，使得多层显示面板适用于多种使用场景，能够提升多层显示面板显示的多样性，还能够降低多层显示面板的能耗。
本公开还提供了一种多层显示面板的控制装置，应用于上述任一实施例提供的多层显示面板中。图15为本公开实施例提供的一种多层显示面板的控制装置的结构示意图，如图15所示，控制装置包括：
