本申请提供的阵列基板及制作方法、显示面板、显示装置、显示套件，旨在解决现有技术的如上技术问题。

在一些实施例中，吸收粒子2011与反射粒子2012的数量相等。
需要说明的是，微胶囊201内填充满吸收粒子2011和反射粒子2012，吸收粒子2011与反射粒子2012的数量相等，吸收粒子2011被磁场吸引后，相应的位置，可以被反射粒子2012填充，避免了粒子之间的空隙造成的漏光。
本申请实施例还提供了一种显示面板，图3为本申请实施例提供的一种显示面板的结构示意图，如图3所示，该显示面板300包括如上述实施例提供的阵列基板10，以及与阵列基板10对盒设置的彩膜基板20；其中反射层102位于衬底基板101远离彩膜基板20的一侧。
需要说明的是，为了避免衬底基板101与彩膜基板20之间的厚度过厚，可以使反射层102位于衬底基板101远离彩膜基板20的一侧，有效减少厚度，提高显示效果。
图4为本申请实施例提供的另一种显示面板的结构示意图，如图4所示，该显示面板300还包括：依次位于彩膜基板20远离阵列基板10一侧的散射膜30、四分之一波片40、半波片50、及偏光片60。
需要说明的是，可以将散射膜30、四分之一波片40、半波片50、及偏光片60集成为一层膜70，将该层膜贴附于彩膜基板20上，减小膜层厚度，达到更好的显示效果(参见图10)。
下面简单介绍本申请实施例提供的显示面板的显示原理：
如图4所示，外界自然光从阵列基板10上方入射，光线经过偏光片60形成具有第一方向的线偏振光，具有第一方向的线偏振光经过半波片50，具有第一方向的线偏振光进行旋转指定的角度，形成具有第二方向的线偏振光，具有第二方向的线偏振光经过四分之一波片40，形成圆偏振光，再经过散射膜30入射至反射层102。当吸收粒子2011位于反射层102的上方时，吸收粒子2011将光线吸收，不形成反射。当反射粒子2012位于反射层102的上方时，反射粒子2012对光线进行反射。经过反射层102反射的圆偏振光入射至彩膜基板20，光线呈现相应的颜色后，经过彩膜基板20入射至散射膜30，光线进行散射变得更加均匀。圆偏振光经过四分之一波片40形成具有与第二方向相同的线偏振光，具有与第二方向相同的线偏振光经过半波片50，恢复至具有与第一方向相同的线偏振光，并经过偏光片60出射，实现反射型显示面板的显示。
本申请实施例还提供了一种显示装置，图5为本申请实施例提供的一种显示装置的结构示意图，如图5所示，该显示装置500包括：上述实施例提供的显示面板300，以及磁场产生装置400，磁场产生装置400位于反射层102远离彩膜基板20的一侧。
需要说明的是，磁场产生装置400可以通电产生磁场，对吸收粒子2011进行吸引，实现显示及手写功能。
图6为本申请实施例提供的一种磁场产生装置的结构示意图，如图6所示，该磁场产生装置400包括：第一导电线圈601、第一电源602和第一开关603。
第一导电线圈601与第一电源602及第一开关603串联连接，且第一导电线圈601在衬底基板101上的正投影区域与反射层102在衬底基板101上的正投影区域完全重叠。
需要说明的是，第一导电线圈601在衬底基板101上的正投影区域与反射层102在衬底基板101上的正投影区域完全重叠，保证阵列基板10包括的所有的吸收粒子2011可以被磁场产生装置400产生的磁场吸引，提高显示效果。
本申请实施例还提供了一种显示套件，图7为本申请实施例提供的一种显示套件的结构示意图，如图7所示，该显示套件包括上述实施例提供的显示装置500和用于在显示面板300表面进行书写操作的触控笔700。
下面详细介绍一下本申请实施例中的显示套件的具体工作过程。
在每次使用前，磁场产生装置400会提前通电，产生磁场，由于吸收粒子2011具有磁性，吸收粒子2011被磁场吸引，位于靠近磁场产生装置400的一侧，反射粒子2012不受磁场影响，位于远离磁场产生装置400的一侧，此时显示面板任何位置均可以反射光线，外界环境光源充足的情况下，显示面板的显示内容由阵列基板对像素点的液晶偏转方向控制实现；在磁场产生装置400持续产生磁场的情况下，即使触控笔700在显示面板表面书写操作，显示内容不会随触控笔700书写而变化，显示面板可实现正常的显示功能。
当磁场产生装置处于断电状态时，不产生磁场，且在显示面板处于通电状态情况下，触控笔700在显示面板表面书写操作，在触控笔700书写位置吸收粒子2011被触控笔700产生的磁场吸引至靠近触控笔700的一侧，此时反射粒子2012位于远离触控笔700的一侧，这种情况下，反射粒子2012被吸收粒子2011遮挡，即使显示面板处于通电状态，液晶处于偏转状态，书写位置处也无法反射出外部光线，可实现显示面板的书写操作，书写内容可通过磁场产生装置通电来擦除。
当磁场产生装置处于断电状态时，不产生磁场，且在显示面板也处于断电状态情况下，触控笔700在显示面板表面书写操作时，反射粒子2012被吸收粒子2011遮挡，书写位置处无法反射出外部光线，可实现显示面板断电时的书写操作，书写内容可通 过磁场产生装置通电来擦除。
图8为本申请实施例提供的一种触控笔的结构示意图，如图8所示，该触控笔700包括：笔芯701、第二导电线圈702、第二电源703和第二开关704。
第二导电线圈702与第二电源703及第二开关704串联连接，且第二导电线圈702缠绕于笔芯701周围。
需要说明的是，第二电源703可以为第二导电线圈702提供电流，使得第二导电线圈702在电流的驱动下产生磁场，并将磁场通过笔芯701传导，对具有磁性的粒子进行吸引。
在一些实施例中，磁场产生装置400包括第一导电线圈601，第二导电线圈702产生的磁场强度小于第一导电线圈601产生的磁场强度。
需要说明的是，在磁场产生装置400持续通电时，第二导电线圈702产生的磁场强度小于第一导电线圈601产生的磁场强度，磁场产生装置400更容易吸引具有磁性的黑色吸收粒子2011，使得触控笔700对吸收粒子2011的吸引不起作用，磁场产生装置400可以将吸收粒子2011吸引至反射层102底部，实现显示面板正常的显示及反射功能。
在一些实施例中，笔芯701可以采用软铁材料制成。
本申请实施例还提供了一种阵列基板的制作方法，该制作方法包括：提供一衬底基板，在衬底基板一侧制作包括多个微胶囊的反射层；其中：每个微胶囊包括：多个反射粒子和多个吸收粒子；吸收粒子为磁性粒子，用于吸收光线；反射粒子为非磁性粒子，用于反射光线。
在一些实施例中，上述在衬底基板一侧制作包括多个微胶囊的反射层，包括：
提供一保护基板，保护基板与衬底基板相对设置；在衬底基板和保护基板内部封装墨水层，墨水层中分布有多个微胶囊，每一微胶囊中封装有多个反射粒子和多个吸收粒子。
在一些实施例中，上述多个吸收粒子的制作方法包括：
在非磁性粒子表面沉积纳米磁性层，纳米磁性层的颜色为黑色。
具体实施时，非磁性粒子可以为黑色粒子，在黑色粒子表面采用化学镀方法进行纳米磁性层的沉积，纳米磁性层的颜色为黑色。当然，实际制作过程中，纳米磁性层的颜色也可以不是黑色，这时需要再采用化学镀方式在纳米磁性层表面沉积颜色为黑色的颜色涂层。
图9a-图9g为本申请实施例提供的一种显示面板的制作方法，下面结合附图详细介绍包括本申请实施例提供的阵列基板的显示面板的制作方法。
如图9a所示，首先，制作一阵列基板10，阵列基板10中各膜层的制作方法与常规反射型液晶显示面板的阵列基板的各膜层的制作方法相同，这里不再赘述。
接着，如图9b所示，在阵列基板10四周涂覆第一封框胶901，第一封框胶901的具体涂覆方法与现有技术相同，这里不再赘述。
接着，如图9c所示，在第一封框胶901构成的空间内注入液晶902，形成液晶层903，液晶902的具体注入方法与现有技术相同，这里不再赘述。
接着，如图9d所示，制作彩膜基板20，并将彩膜基板20与阵列基板10对盒，彩膜基板20的具体制作方法，以及对盒的具体方法均与现有技术相同，这里不再赘述。
接着，如图9e所示，在阵列基板10远离彩膜基板20的一侧的四周涂覆第二封框胶904，第二封框胶904的具体涂覆方法可以与第一封框胶901的涂覆方法相同。
接着，如图9f所示，在第二封框胶904构成的空间内制作墨水层905，墨水层905中分布有多个微胶囊201，每一微胶囊中封装有多个反射粒子2012和多个吸收粒子2011。
接着，如图9g所示，将阵列基板10、墨水层905和保护基板906通过粘贴工艺进行封装，本申请实施例中的保护基板906可以为透明基板，也可以为非透明基板。
