 本发明的实施方式
下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例提供了一种显示面板，以下将进行详细说明。
请参阅图1，图1是本申请实施例提供的显示面板的第一结构示意图。该显示面板100可以包括第一基板10、第二基板20、挡墙30和电泳材料40。
其中，第一基板10可以为柔性显示基板。该第一基板10的材料可以包括聚酰亚胺（Polyimide，PI）等有机柔性材料。
其中，该第二基板20与第一基板10相对设置。在一些实施例中，该第二基板20可以包括层叠设置的衬底层21、金属层22、第一保护层23、纳米颗粒层24和第二保护层25，具体可以参阅图2。
需要说明的是，在本申请的描述中，术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”、“第三”的特征可以明示或者隐含地包括一个或者更多个所述特征。
需要说明的是，在本申请实施例的描述中，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
其中，衬底层21可以为柔性衬底。该衬底层21的材料可以包括聚酰亚胺（Polyimide，PI）等有机柔性材料。该金属层22和纳米颗粒层24的材料可以包括镁、铝、钼、铜、银、钛等金属材料。第一保护层23和第二保护层25的材料可以包括氧化铝、氮化硅、氧化硅等材料。
在一些实施例中，如图3所示，该纳米颗粒层24可以包括若干阵列分布的金属纳米颗粒241。其中，该金属纳米颗粒241的尺寸可以为3纳米-200纳米，相邻的金属纳米颗粒241之间的间距可以为3纳米-400纳米。该金属纳米颗粒241的形状可以为方形、矩形、圆形或其他形状。
需要说明的是，该纳米颗粒层24中的金属等离子可以与金属层22中的金属等离子发生共振产生结构色，从而使得第二基板20可以反射出可见光。
在一些实施例中，可以通过对该纳米颗粒层24中的金属纳米颗粒241的尺寸大小以及相邻的金属纳米颗粒241之间的间距进行相应的调节，使得第二基板20可以反射出红光、绿光、蓝光或其他颜色的可见光。
其中，挡墙30可以设置于第一基板10和第二基板20之间。该挡墙30可以与第一基板10、第二基板20围设成多个收容空间31。需要说明的是，该挡墙30的材料可以根据实际情况选定。比如疏水性材料或亲水性材料。
在一些实施例中，该收容空间31可以包括第一收容空间311、第二收容空间312或第三收容空间313。其中，位于第一收容空间311的相邻金属纳米颗粒241之间的间距为第一间距，位于第二收容空间312的相邻金属纳米颗粒241之间的间距为第二间距，位于第三收容空间313的相邻金属纳米颗粒241之间的间距为第三间距。可以理解的是，为了使得第一收容空间311、第二收容空间312和第三收容空间313可以分别反射出红光、绿光或蓝光，第一间距、第二间距和第三间距互不相同。即是，第一间距与第二间距不相同，第一间距与第三间距不相同，第二间距与第三间距不相同。在一些实施例中，第一收容空间311可以为红光区域，第二收容空间312可以为绿光区域，第三收容空间313可以为蓝光区域。
其中，电泳材料40可以收容于收容空间31内。其中，该电泳材料40可以包括电泳颗粒41和电泳液42。该电泳材料40可以为电子墨水。可以理解的是，该电泳颗粒41可以在电场的作用下进行移动。
需要说明的是，该电泳颗粒41可以是有机颗粒、无机颗粒或彩色微胶囊颗粒。其中，有机颗粒可以包括聚合物球及类似的化合物颜料颗粒。无机颗粒可以包括二氧化硅、二氧化钛或炭黑颗粒等。彩色微胶囊可以是将彩色溶液包裹成鱼肝油式的颗粒。在本申请实施例中，该电泳颗粒41为黑色带电粒子。
为了使得电泳颗粒41可以在不存在电场时吸附于挡墙30上，以便显示面板100呈反射状态，实现彩色显示。在一些实施例中，可以对电泳颗粒41和挡墙30进行相应的设置。具体的，当挡墙30的材料为疏水性材料时，可以对电泳颗粒41的表面做疏水性处理，使得电泳颗粒41变为表面具有疏水性的颗粒。或当挡墙30的材料为亲水性材料时，可以对电泳颗粒41的表面做亲水性处理，使得电泳颗粒41变为表面具有亲水性的颗粒。可以理解的是，根据相似相吸原则，当挡墙30的材料与电泳颗粒41的表面具有同一性质时，在不存在电场时，电泳颗粒41会吸附于挡墙30上，如图4所示。
需要说明的是，当存在电场时，电泳颗粒41可以在电场的作用下朝第一基板10运动，最终移动到第一基板10的表面，入射光可以被电泳颗粒41吸收，使得显示面板100呈暗态，具体可以如图5所示。
其中，该显示面板100还包括第一电极50和第二电极60。其中，第一电极50可以设置于第一基板10上。第二电极60可以设置于第二基板20上。
可以理解的是，当需要使得该显示面板100从暗态恢复到反射状态时，可以停止对显示面板100施加电压，以使得电泳颗粒41可以根据相似相吸原则从第一基板10的表面朝挡墙30移动，最终吸附于挡墙30上。
然而，仅通过相似相吸原则使得显示面板100从暗态恢复到反射状态的速度较慢，从而会导致显示面板100的响应速度较慢。在一些实施例中，为了加快显示面板100从暗态恢复到反射状态的速度，可以对第一电极50和第二电极60进行相应的处理。
具体的，可以如图6或图7所示，将第一电极50设置为透明电极，该第一电极50覆盖第一基板10朝向第二基板20的一侧。可以理解的是，为了节省制造成本，该第一电极50可以分成多个部分，仅对挡墙30之间的第一基板10朝向第二基板20的一侧的部分。即是，该第一电极50可以设置于挡墙30之间。具体的，可以将第二电极60分为多个部分，并将其设置于第二基板20与挡墙30构成的拐角处。需要说明的是，当需要显示面板100呈暗态时，可以对第一电极50施加与电泳颗粒41极性相反的电压，使得电泳颗粒41快速朝第一基板10移动，并吸附于第一基板10上，如图6所示。入射光可以被电泳颗粒41吸收，使得显示面板100呈暗态。当需要将显示面板100从暗态恢复到反射状态时，可以停止对第一电极50施加电压，并对第二电极60施加与电泳颗粒41极性相反的电压，使得电泳颗粒41快速移动到第二基板20与挡墙30构成的拐角处，入射光可以到达第二基板20，使得显示面板100呈反射状态，实现彩色显示，如图7所示。
由上，本申请实施例提供的显示面板100可以包括第一基板10、第二基板20、挡墙30和电泳材料40。其中，第二基板20与第一基板10相对设置，该第二基板20包括层叠设置的衬底层21、金属层22、第一保护层23、纳米颗粒层24和第二保护层25，第二保护层25位于第二基板20朝向第一基板10的一侧；挡墙30设置于第一基板10和第二基板20之间，挡墙30与第一基板10、第二基板20围设成多个收容空间31；电泳材料40收容于所述收容空间内31。本方案可以通过第二基板20的纳米颗粒层24中的金属纳米颗粒241的金属等离子与金属层22中的金属等离子发生共振产生结构色，使得入射光到达第二基板20后可以反射出相应的可见光。该可见光不需要经过其他处理，比如过滤等，便可以直接从第一基板10射出，从而减少了光的消耗，提高了显示面板100对光的利用率。并且，由于可以直接由第二基板20反射出相应的可见光，不需要经过色阻或彩色油墨的过滤即可实现彩色显示，即是减少了对光的阻挡，减少了光的消耗，从而提高了显示面板100的穿透率以及显示面板100的分辨率，进而提高显示面板100的显示效果。
以上对本申请实施例所提供的一种显示面板进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的技术方案及其核心思想；本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例的技术方案的范围。
