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显示面板的结构示意图，如图1所示，显示面板10包括：第一显示模块100，以及叠放于第一显示模块100出光侧的第二显示模块200。
其中，第一显示模块100包括：像素阵列110和位于像素阵列110靠近第二显示模块200一侧的保护层120，像素阵列110包括阵列分布的多个像素单元111，每个像素单元111中包括多个子像素单元111a。
第二显示模块200包括：遮光层210和显示粒子220，遮光层210位于保护层120远离像素阵列110的一侧，其中，遮光层210包括：多个遮光单元211，遮光单元211正对相邻子像素单元之间的区域，显示粒子220位于相邻遮光单元211之间的区域。
第一显示模块100和第二显示模块200，用于显示图像。
像素阵列110包括沿X方向和Y方向阵列分布的多个像素单元111，如图1所示，每个像素单元111可以包括三个子像素单元111a，三个子像素单元111a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，通过红色子像素单元、绿色子像素单元和蓝色子像素单元，第一显示模块100可以显示彩色图像。在其他实施方式中，每个像素单元111也可以包括四个子像素单元111a，四个子像素单元111a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，对于子像素单元的种类不做具体限制。
示例性的，第一显示模块100的制备工艺可以包括如下：提供一衬底130，在衬底130的一侧设置驱动阵列层140，驱动阵列层140包括阵列分布的驱动单元，驱动单元用于驱动对应的子像素单元111a发光。在驱动阵列层140远离衬底130的一侧依次形成像素阵列110和保护层120，保护层120能够阻隔第一显示模块100的内部与外部空气，保护第一显示模块100的内部结构免受空气中水分的影响，还能够缓冲第一显示模块100受到的外部应力，起到保护作用。本实施例仅示例性展示第一显示模块的工艺，并不对第一显示模块的工艺进行具体限制。
相邻子像素单元111a之间存在一定的间隙，在该间隙对应的区域设置有金属走线，这些金属走线用于电连接对应的子像素单元111a和驱动电路，使得驱动电路可以控制子像素单元111a发光。子像素单元111a位于第一显示模块100的显示区内，也就是说，金属走线位于显示区内，当外界环境光照射至第一显示模块100内部时，第一显示模块100内的金属走线会对外界环境光进行反射，反射的外界环境光会通过第一显示模块100的出光面出射，导致第一显示模块100射出的外界环境光的强度较高，用户观看第一显示模块100显示的图像时会出现眩光问题。
示例性的，在保护层120远离像素阵列110的一侧涂覆黑色有机胶，刻蚀黑色有机胶层并且经固化形成多个遮光单元211，且遮光单元211正对相邻子像素单元111a之间的区域。遮光单元211可以是沿X方向延伸沿Y方向排列的遮光条，和/或可以是沿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，本实施例对遮光单元的具体形态和遮光块的颜色不做具体限制。
基于上述实施例，在相邻遮光单元211之间的区域填充显示粒子220，显示粒子220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，第二显示模块200可以显示黑白图像。
相邻子像素单元111a之间设置有金属走线，遮光单元211能够覆盖第一显示模块100内的金属走线。若第一显示模块100进行图像显示，子像素单元111a发射的光束通过相邻遮光单元211之间的区域射出，如图1所示(实线箭头表示子像素单元111a发射的用于显示图像的光束)，也就是说遮光单元211不会遮挡子像素单元111a发射的光束，避免对第 一显示模块100的显示效果造成影响。
在第一显示模块100内的子像素单元111a发射光束以显示图像的同时，外界环境光也会照射至第一显示模块100的内部，由于遮光单元211位于第一显示模块100的出光侧，因此，外界环境光照射至第一显示模块100之前，遮光单元211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)，降低入射至第一显示模块100内部的外界环境光的强度，从而能够降低第一显示模块100射出的外界环境光的强度。此外，入射至第一显示模块100内部的外界环境光，部分会被金属走线反射，遮光单元211能够阻挡部分反射的外界环境光从第一显示模块100的出光面射出，进一步降低第一显示模块100射出的外界环境光的强度，如此解决了显示面板10的眩光问题，起到保护用户眼睛的作用。
本实施例中，显示面板包括第一显示模块，以及叠放于第一显示模块出光侧的第二显示模块；第一显示模块包括：像素阵列和位于像素阵列靠近第二显示模块一侧的保护层，像素阵列包括阵列分布的多个像素单元，每个像素单元中包括多个子像素单元；第二显示模块包括：遮光层和显示粒子，遮光层位于保护层远离像素阵列的一侧；遮光层包括：多个遮光单元，遮光单元正对相邻子像素单元之间的区域，显示粒子位于相邻遮光单元之间的区域，第一显示模块和第二显示模块，均可以显示图像，如此，遮光层不会遮挡子像素单元射出的光束，避免对第一显示模块的显示质量造成影响；另外，遮光层能够遮挡部分外界环境光，降低入射至第一显示模块内部的外界环境光的强度，也就是说，能够降低第一显示模块射出的外界环境光的强度，遮光单元还能够遮挡第一显示模块内金属走线反射的外界环境光，进一步降低第一显示模块射出的外界环境光的强度，从而能够解决眩光问题，起到保护用户眼睛的作用。
可选的，第一显示模块100，用于在第一工作模式下显示图像，在第二工作模式下向第二显示模块200提供背光。第二显示模块200，用于在第二工作模式和第三工作模式下显示图像。
显示面板10处于第一工作模式时，第一显示模块100中子像素单元111a发射的光束穿过第二显示模块200中相邻遮光单元211之间的区域，并从第二显示模块200的出光面出射。如此，通过第一显示模块100可以显示彩色图像。
显示面板10处于第三工作模式时，可以关闭第一显示模块100，而第二显示模块200中显示粒子220分布于相邻遮光单元211之间区域，一部分显示粒子220可以吸收外界环境光，另一部分显示粒子220可以反射外界环境光，如此，第二显示模块200在外界环境 光的照射下可以显示黑白图像。
显示面板10处于第二工作模式时，显示粒子220分布于相邻遮光单元211之间区域，第一显示模块100中子像素单元111a发射的光束照射至位于相邻遮光单元211之间区域的显示粒子220。显示粒子220中的一部分可以吸收子像素单元111a发射的光束，另一部分可以反射子像素单元111a发射的光束，如此，第二显示模块200以第一显示模块100发射的光束作为背光，可以在较暗的环境下显示黑白图像。
综上所述，本实施例中，显示面板既可以通过第一显示模块显示彩色图像，又可以通过第二显示模块显示黑白图像，还可以在较暗的环境下，以第一显示模块发射的光束作为背光通过第二显示模块显示黑白图像，使得显示面板能够适用于多种显示场景，提升显示面板显示的多样性，还能够降低显示面板的能耗。
可选的，图2为本公开实施例提供的另一种显示面板的结构示意图，图3为本公开实施例提供的又一种显示面板的结构示意图，结合图2和图3所示，遮光单元211包括：第一表面211a、第二表面211b和第三表面211c，其中，第一表面211a为遮光单元211靠近保护层120一侧的表面，第二表面211b与第一表面211a相对，第三表面211c连接第一表面211a和第二表面211b，且第三表面211c为正对相邻子像素单元111a之间的区域。
其中，第一表面211a在保护层120的垂直投影位于第二表面211b在保护层120的垂直投影内。
结合图2和图3所示，第二显示模块200还包括：电极230，电极230覆盖第三表面211c。电极230，用于在第一工作模式下，吸附显示粒子220，以使第二显示模块200透光，在第二工作模式和第三工作模式下，驱动显示粒子220显示图像。
具体的，如图2和图3所示，遮光单元211远离保护层120一侧的表面为第二表面211b，遮光单元211靠近保护层120一侧的表面为第一表面211a，第二表面211b可以覆盖第一表面211a。示例性的，遮光单元211在XZ平面的垂直投影为倒梯形，如图2和图3所示，第二表面211b在XZ平面的垂直投影即为倒梯形的长边，第一表面211a在XZ平面的垂直投影即为倒梯形的短边，第三表面211c在XZ平面的垂直投影即为倒梯形的两个腰。
形成遮光层210后，在第三表面211c进行电极蒸镀，形成覆盖第三表面211c的电极230。基于上述实施例，电极230在XZ平面的垂直投影覆盖倒梯形的腰，如图2和图3所示。电极230与驱动电路电连接，可以根据驱动电路提供的电信号产生相应的电场，以驱动显示粒子220移动。
若显示面板10处于第一工作模式，电极230根据接收到第一电信号产生第一电场，在第一电场的作用下，显示粒子220向电极230所在区域进行移动，以使显示粒子吸附于电极230，如图2所示，相邻遮光单元211之间的区域为可透光状态。如此，第一显示模块100发射的光束可以通过相邻遮光单元211之间的区域，即可以透过第二显示模块200，从而确保显示面板10可以通过第一显示模块100显示彩色图像。此外，由于第二表面211b可以覆盖第一表面211a，故而第一表面211a也可以覆盖显示粒子220，使得第一显示模块100显示图像时，可以避免显示粒子220对显示效果造成影响。
若显示面板10处于第二工作模式，第一显示模块100可以发射光束，电极230根据接收到的第二电信号，产生第二电场，在第二电场的作用下，显示粒子220分布于相邻遮光单元211之间的区域，如图3所示。由于相邻遮光单元211之间的区域充满显示粒子220，第一显示模块100发射的光束并不会通过相邻遮光单元211之间的区域，而是被显示粒子220反射和吸收，从而确保显示面板10在较暗环境下，能够以第一显示模块100发射的光束作为背光，通过第二显示模块200显示黑白图像。
若显示面板10处于第三工作模式，第一显示模块处于关闭状态，电极230根据接收到的第三电信号，产生第三电场，在第三电场的作用下，显示粒子220分布于相邻遮光单元211之间的区域，对外界环境光进行反射和吸收，从而确保显示面板10在较亮环境下，可以通过第二显示模块200显示黑白图像。
可选的，图4为本公开实施例提供的一种显示面板的俯视结构示意图，如图4所示，遮光层210包括：多个沿第一方向延伸沿第二方向排列的遮光条212，以及多个沿第二方向延伸沿第一方向排列的遮光条212，第一方向和第二方向分别为像素阵列110的行方向和列方向。
其中，在与遮光条212延伸方向垂直的平面上，遮光条212的垂直投影为倒梯形、倒三角形、T形中的至少一种。
示例性的，如图4所示，像素阵列110的行方向为X方向，列方向为Y方向，即像素阵列110中的多个子像素单元111a沿X方向和Y方向阵列分布。遮光层210包括多个第一遮光条212a和多个第二遮光条212b，其中，第一遮光条212a沿X方向延伸沿Y方向排列，第二遮光条212b沿Y方向延伸沿X方向排列。遮光条212可以尽可能多的覆盖相邻子像素单元111a之间的区域，阻挡较多的外界环境光，还能够阻挡较多的第一显示模块内反射的外界环境光从第一显示模块射出，降低第一显示模块射出的外界环境光的强度， 使得显示面板具有较好的防眩光效果。
在其他实施方式中，遮光层210可以包括多个沿X方向延伸沿Y方向排列的遮光条，或者包括多个沿Y方向延伸沿X方向排列的遮光条，本实施例对此不做具体限制。
第一遮光条212a在YZ平面上的垂直投影可以为倒梯形，第二遮光条212b在XZ平面上的垂直投影可以为倒梯形，如图2所示，使得第一显示模块在显示图像时，第二显示模块中的显示粒子反射的光束会被遮光条遮挡，从而不会对第一显示模块的显示效果造成影响。另外，通过现有的刻蚀工艺即可制备倒梯形的遮光条212，实现方式简单，具有较强的可操作性。
在其他实施方式中，第一遮光条212a在YZ平面上的垂直投影以及第二遮光条212b在XZ平面上的垂直投影还可以为倒三角形，或者T形；或者还可以为倒梯形、倒三角形以及T形中的两种，或者还可以为倒梯形、倒三角形和T形，本实施例对此，不做具体限制。
需要说明的是，本实施例中仅示例性展示了像素阵列110的行方向为X方向，像素阵列110的列方向为Y方向，并不作为对像素阵列110的行方向和列方向的限制。
可选的，图5为本公开实施例提供的另一种显示面板的俯视结构示意图，如图5所示，第二表面211b在像素阵列110所在平面的垂直投影，位于相邻子像素单元111a之间的区域内。
示例性的，如图5所示，第二表面211b在像素阵列110所在平面的垂直投影，位于相邻子像素单元111a之间的区域内，使得遮光单元211对子像素单元111a发射的光束的遮挡尽可能的小，能够避免遮光单元211对第一显示模块显示的图像造成遮挡。
可选的，图6为本公开实施例提供的又一种显示面板的结构示意图，如图6所示，第二显示模块200还包括：透明衬底240。
其中，透明衬底240位于保护层120与遮光层210之间。
示例性的，第二显示模块200的制备工艺过程包括：提供一透明衬底240，在透明衬底240上通过涂覆黑色有机胶，并对有机胶层进行刻蚀，固化后形成遮光层210；在相邻遮光单元211正对的表面形成电极，将显示粒子220填充于相邻遮光单元211之间的区域；在遮光层210远离透明衬底240一侧形成封装保护层，将第二显示模块200进行封装。
基于上述实施例，可以将制备好的第二显示模块200叠放于第一显示模块100靠近保护层120的一侧表面，且第二显示模块200中的透明衬底240正对保护层120，将第二显 示模块200与第一显示模块100进行对位，使得第二显示模块200中的遮光单元211正对第一显示模块100中相邻子像素单元111a之间的区域，对位完成后将第二显示模块200固定于第一显示模块100靠近保护层120的一侧，形成如图6所示的显示面板。
本实施例中，可以分别制备第一显示模块和第二显示模块，即可以在同时制备第一显示模块和第二显示模块，能够缩短显示面板的工艺制程时间，利于提高显示面板的出货量。
在其他实施方式中，还可以在保护层120远离像素阵列110的一侧表面直接涂覆黑色有机胶，对有机胶层进行刻蚀以及固化后，形成遮光层210，从而制备如图1所示的显示面板10。本实施例中，无需设置透明衬底，可以减小显示面板的厚度，有利于显示面板的轻薄化发展。
基于上述实施例，可选的，第二显示模块200为电子纸显示屏，第一显示模块100包括：液晶显示屏LCD、有机发光二极管OLED显示屏、微发光二极管Micro LED显示屏中的一种。
示例性的，第二显示模块200为电子纸显示屏，利用第二显示模块200显示图像时，可以节约能源。第一显示模块100可以为LCD，LCD能够显示高色域的彩色图像，故而显示面板10可以在彩色显示场景下，显示高色域的彩色图像，还可以在黑白图像显示的场景下，显示图像的同时节约能源。
需要说明的是，第一显示模块100还可以是OLED显示屏或者Micro LED(Micro Light-Emitting Diode，微发光二极管)显示屏，本实施例对此不做具体限制。

示例性的，如图2所示，遮光单元211包括：第一表面211a、第二表面211b和第三表面211c，其中，第一表面211a为遮光单元211靠近保护层120一侧的表面，第二表面211b与第一表面211a相对，第三表面211c连接第一表面211a和第二表面211b，且第三表面211c为正对相邻子像素单元111a之间的区域，电极230覆盖第三表面211c。电极230与驱动电路电连接，可以根据驱动电路提供的电信号产生相应的电场，以驱动显示粒子220移动。
若显示面板处于第一工作模式，生成第一工作模式指令，驱动电路根据第一工作模式指令生成第一电信号，电极根据第一电信号产生第一电场，在第一电场的作用下，显示粒子向电极所在区域进行移动，以使显示粒子吸附电极所在区域，此时，相邻遮光单元之间的区域为可透光状态。
S1022，控制所述第一显示模块显示图像。
