背景技术
现今社会，广告行业蓬勃发展，大大小小的广告牌随处可见，近年来尤其是在各地高速公路上，广告牌非常直观的展示出品牌的内涵，广受大家的认可。
现有的广告牌一般有两种展示方法，其中一种是将打印好的宣传画直接粘贴在广告墙上，另一种是将显示装置悬挂在广告墙上。但是这两个方法都有弊端：第一种方法，由于通常设置高速公路上的广告墙都放置在很高的支架上，而宣传画需要通过人工粘贴在广告墙上，因此更换广告牌的内容是很不方便的；第二种方法，由于目前的显示装置一般都是通过发光源直接进行显示的，因此，在白天进行户外显示时对显示装置的光强要求是非常高的，否则户外太阳光强较强，人眼很难看清楚画面内容，视觉效果较差。

具体实施方式
下面结合附图，对本公开实施例提供的显示面板、其显示方法及显示装置的具体实施方式进行详细地说明。
附图中各区域的形状大小不反映显示面板的真实比例，目的只是示意说明本公开内容。
本公开实施例提供的一种显示面板，包括多个像素，各像素包括至少一个子像素；如图1所示，其中，各子像素1包括反色盒01和用于控制反色盒01所显示的颜色的控制部02；其中，
反色盒01包括：具有盒腔的盒体11、以及密封于盒腔中的有色材料12和遮挡部13，盒体11的入光面为透明材料，遮挡部13的入光面具有预设的基底颜色；
控制部用于，在有外界光的情况下，根据对应位置处的显示画面控制对应的反色盒中的遮挡部的入光面与盒腔的入光面的相对位置，使反色盒显示遮挡部的入光面的颜色或有色材料的颜色。
这样在有外界光照射的情况下，通过控制部控制反色盒的反射颜色实现显示面板的画面显示。将上述显示面板应用于广告牌，不仅可以避免人工更换广告牌内容所带来的不便，并且由于该显示装置是通过外界光反射实现的显示，因此与现有的通过发光源直接进行显示的显示装置相比，在白天户外进行显示时，视觉效果更佳，并且外界光越强，视觉效果越佳。
进一步地，在具体实施时，由于本公开实施例提供的上述显示面板是利用反色盒中的遮挡部的入光面与盒腔的入光面的相对位置使反色盒显示有色 材料或遮挡部的入光面的颜色实现显示的，因此各子像素的面积相对较大，使上述显示面板尤其适用远距离大型广告牌。这是因为远距离大型广告牌距观看者的距离较远，对显示面板的分辨率的要求相对较低，并且远距离大型广告牌一般都是设置在户外，可以直接利用太阳光作为该显示面板的外界光。
可选地，在本公开实施例提供的上述显示面板中，遮挡部的入光面所具有的预设的基底颜色是一种与有色材料的颜色不相同的颜色。
可选地，在本公开实施例提供的上述显示面板中，有色材料可以为有色液体，也可以为有色的胶状体，只要是有色流体物质都属于本公开的保护范围，在此不作限定。
可选地，在本公开实施例提供的上述显示面板中，有色材料可以为有色油墨。
可选地，在本公开实施例提供的上述显示面板中，多个像素呈矩阵排列，各像素可以包括一个子像素，也可以包括多个子像素，且属于同一像素中的子像素所显示的颜色不相同。
可选地，为了制作方便，以及增大有效显示面积，在本公开实施例提供的上述显示面板中，反色盒呈长方体或立方体，且反色盒的盒腔的入光面为长方形或正方形，在此不作限定。
可选地，在本公开实施例提供的上述显示面板中，在反色盒显示遮挡部的入光面的颜色时，遮挡部的入光面在入光方向上挡住有色材料，在反色盒显示有色材料的颜色时，遮挡部的入光面浸没在有色材料中。
可选地，在本公开实施例提供的上述显示面板中，遮挡部包括至少一块遮挡板，且遮挡板的一侧与盒体的入光面采用可旋转方式固定连接。
例如，如图2a所示，遮挡部13包括一块遮挡板131，且遮挡板131的一侧与和盒体的入光面采用可旋转方式固定连接；或者；
如图2b所示，遮挡部13包括两块遮挡板131，且各遮挡板131的一侧与盒体的入光面采用可旋转方式固定连接。
可选地，在本公开实施例提供的上述显示面板中，遮挡板通过铰链或合页与盒体铰接。
或者，可选地，在本公开实施例提供的上述显示面板中，如图2c所示， 遮挡部13包括一块入光面平行于盒腔的入光面的遮挡板131。
需要说明的是，在本公开实施例提供的上述显示面板中，遮挡板与盒体之间具有一定的间隙，以使遮挡板在移动时，有色材料可以从间隙中流过。
可选地，在本公开实施例提供的上述显示面板中，为了稳定遮挡板，如图2d所示，遮挡板131的入光面的预设区域与盒体的入光面弹性连接，且在自然状态下遮挡板的入光面紧贴盒腔的入光面。
可选地，在本公开实施例提供的上述显示面板中，控制部用于：
当根据对应位置处的显示画面确定对应的反色盒需要显示遮挡部的入光面的颜色时，控制对应的反色盒中的遮挡部的入光面贴近盒腔的入光面，使反色盒显示遮挡部的入光面的颜色；或
当根据对应位置处的显示画面确定对应的反色盒需要显示有色材料的颜色时，控制对应的反色盒中的遮挡部的入光面远离盒腔的入光面，使反色盒显示有色材料的颜色。
这样，当确定反色盒需要显示遮挡部的入光面的颜色时，由于控制遮挡部的入光面贴近盒腔的入光面，从而将有色材料排挤到遮挡部的背光面，使反色盒显示遮挡部的入光面的颜色，当确定反色盒需要显示有色材料颜色时，控制遮挡部的入光面远离盒腔的入光面，使有色材料又充满遮挡部的入光面与盒腔的入光面之间，从而使反色盒显示有色材料的颜色。
需要说明的是，在本公开实施例提供的上述显示面板中，遮挡部的入光面远离盒腔的入光面，可以是指遮挡部以整体平移的方式使入光面远离盒腔的入光面，也可以是指遮挡部以一侧为轴，以旋转的方式使入光面远离盒腔的入光面，在此不作限定。
可选地，在本公开实施例提供的上述显示面板中，遮挡板包括有磁性材料。
可选地，在本公开实施例提供的上述显示面板中，遮挡板的材料可以为磁性材料；或遮挡板中掺杂有磁性材料；或如图2e和图2f所示，遮挡板131中内嵌有磁性材料轴1310。
可选地，在本公开实施例提供的上述显示面板中，磁性材料可以为铁、钴、镍等，在此不作限定。
由于遮挡板中包括有磁性材料，因此可以采用电磁铁来控制遮挡板的移动。
下面通过具体实施例对本公开进行详细说明。需要说明的是，下面的实施例是为了更好的解释本公开，但不限制本公开。
实施例一：
可选地，在本公开实施例提供的上述显示面板中，如图3a至图3f所示，控制部02包括第一电磁铁21和用于根据对应位置处的显示画面向第一电磁铁21提供电压的第一电压单元22；其中，
如图3a、图3c和图3e所示，第一电磁铁21位于反色盒01的入光侧，或如图3b、图3d和图3f所示，第一电磁铁21位于反色盒01的背光侧；
第一电压单元22用于，当根据对应位置处的显示画面，确定反色盒01需要显示遮挡部13的入光面的颜色时，向第一电磁铁21输出第一电压，使第一电磁铁21控制遮挡部13的入光面在入光方向上挡住有色材料12；当根据对应位置处的显示画面，确定反色盒01需要显示有色材料12颜色时，向第一电磁铁21输出第二电压，使第一电磁铁21控制遮挡部13的入光面浸没在有色材料12中。
可选地，在本公开实施例提供的上述显示面板中，如图3b、图3d和图3f所示，第一电磁铁21位于反色盒01的背光侧，这样可以避免控制部占据显示面积。
在具体实施时，本公开实施例提供的上述显示面板的工作原理可以按照遮挡部的结构分为以下几种情况。
第一种情况：组成遮挡部的遮挡板是采用可旋转方式与盒体固定连接的。
当第一电磁铁位于反色盒的背光侧时，当根据对应位置处的显示画面，确定反色盒需要显示遮挡部的入光面的颜色时，第一电压单元向第一电磁铁输出第一电压，使第一电磁铁对遮挡部中的磁性材料产生排斥力，从而使遮挡部向盒腔的入光面一侧旋转，最终使遮挡部的入光面贴近盒腔的入光面，进而使遮挡部的入光面在入光方向上挡住有色材料；当根据对应位置处的显示画面，确定反色盒需要显示所述有色材料颜色时，第一电压单元向第一电磁铁输出第二电压，使第一电磁铁对遮挡部中的磁性材料产生吸引力，从而 使遮挡部向盒腔的背光面一侧旋转，最终使遮挡部的入光面远离盒腔的入光面，进而使遮挡部的入光面浸没在有色材料中。
反之，当第一电磁铁位于反色盒的入光侧时，当根据对应位置处的显示画面，确定反色盒需要显示遮挡部的入光面的颜色时，第一电压单元向第一电磁铁输出第一电压，使第一电磁铁对遮挡部中的磁性材料产生吸引力，从而使遮挡部向盒腔的入光面一侧旋转，最终使遮挡部的入光面贴近盒腔的入光面，进而使遮挡部的入光面在入光方向上挡住有色材料；当根据对应位置处的显示画面，确定反色盒需要显示所述有色材料颜色时，第一电压单元向第一电磁铁输出第二电压，使第一电磁铁对遮挡部中的磁性材料产生排斥力，从而使遮挡部向盒腔的背光面一侧旋转，最终使遮挡部的入光面远离盒腔的入光面，进而使遮挡部的入光面浸没在有色材料中。
第二种情况：遮挡部是一块入光面平行于盒腔的入光面的遮挡板。
当第一电磁铁位于反色盒的背光侧时，当根据对应位置处的显示画面，确定反色盒需要显示遮挡部的入光面的颜色时，第一电压单元向第一电磁铁输出第一电压，使第一电磁铁对遮挡部中的磁性材料产生排斥力，从而使遮挡部向盒腔的入光面一侧平移，最终使遮挡部的入光面贴近盒腔的入光面，进而使遮挡部的入光面在入光方向上挡住有色材料；当根据对应位置处的显示画面，确定反色盒需要显示所述有色材料颜色时，第一电压单元向第一电磁铁输出第二电压，使第一电磁铁对遮挡部中的磁性材料产生吸引力，从而使遮挡部向盒腔的背光面一侧平移，最终使遮挡部的入光面远离盒腔的入光面，进而使遮挡部的入光面浸没在有色材料中。
反之，当第一电磁铁位于反色盒的入光侧时，当根据对应位置处的显示画面，确定反色盒需要显示遮挡部的入光面的颜色时，第一电压单元向第一电磁铁输出第一电压，使第一电磁铁对遮挡部中的磁性材料产生吸引力，从而使遮挡部向盒腔的入光面一侧平移，最终使遮挡部的入光面贴近盒腔的入光面，进而使遮挡部的入光面在入光方向上挡住有色材料；当根据对应位置处的显示画面，确定反色盒需要显示所述有色材料颜色时，第一电压单元向第一电磁铁输出第二电压，使第一电磁铁对遮挡部中的磁性材料产生排斥力，从而使遮挡部向盒腔的背光面一侧平移，最终使遮挡部的入光面远离盒腔的 入光面，进而使遮挡部的入光面浸没在有色材料中。
第三种情况：遮挡部是一块入光面平行于盒腔的入光面的遮挡板，且该遮挡板的入光面的预设区域与盒体的入光面弹性连接，且在自然状态下该遮挡板的入光面紧贴盒腔的入光面。
当第一电磁铁位于反色盒的背光侧时，当根据对应位置处的显示画面，确定反色盒需要显示遮挡部的入光面的颜色时，第一电压单元向第一电磁铁输出第一电压，第一电压最好为0伏，这样遮挡部恢复自然状态，从而使遮挡部的入光面贴近盒腔的入光面，进而使遮挡部的入光面在入光方向上挡住有色材料；当根据对应位置处的显示画面，确定反色盒需要显示所述有色材料颜色时，第一电压单元向第一电磁铁输出第二电压，使第一电磁铁对遮挡部中的磁性材料产生吸引力，从而使遮挡部向盒腔的背光面一侧平移，最终使遮挡部的入光面远离盒腔的入光面，进而使遮挡部的入光面浸没在有色材料中。
反之，当第一电磁铁位于反色盒的入光侧时，当根据对应位置处的显示画面，确定反色盒需要显示遮挡部的入光面的颜色时，第一电压单元向第一电磁铁输出第一电压，第一电压最好为0伏，这样遮挡部恢复自然状态，从而使遮挡部的入光面贴近盒腔的入光面，进而使遮挡部的入光面在入光方向上挡住有色材料；当根据对应位置处的显示画面，确定反色盒需要显示所述有色材料颜色时，第一电压单元向第一电磁铁输出第二电压，使第一电磁铁对遮挡部中的磁性材料产生排斥力，从而使遮挡部向盒腔的背光面一侧平移，最终使遮挡部的入光面远离盒腔的入光面，进而使遮挡部的入光面浸没在有色材料中。
可选地，针对第一种情况和第二种情况的显示面板，第一电压单元在第一电磁铁控制遮挡部的入光面贴近盒腔的入光面之后停止向第一电磁铁输出电压；和/或，第一电压单元在第一电磁铁控制遮挡部的入光面远离盒腔的入光面之后停止向第一电磁铁输出电压。这样显示面板只有在各子像素需要变换显示颜色时才通电，因此可以达到节能的效果。
实施例二：
可选地，在本公开实施例提供的上述显示面板中，控制部也可以包括两 块磁铁，具体如图4a至图4c所示，控制部02包括第二电磁铁31、第三电磁铁41、用于根据对应位置处的显示画面向第二电磁铁31提供电压的第二电压单元32、和用于根据对应位置处的显示画面向第三电磁铁41提供电压的第三电压单元42；其中，
第二电磁体铁31位于反射盒01的入光侧或背光侧，第三电磁铁41位于反色盒01的背光侧或入光侧(图4a至图4c均是以第二电磁体铁31位于反射盒01的入光侧，第三电磁铁41位于反色盒01的背光侧为例)；
第二电压单元32用于，当根据对应位置处的显示画面，确定反色盒01需要显示遮挡部13的入光面的颜色时，向第二电磁铁31输出电压，使第二电磁铁31控制遮挡部13的入光面在入光方向上挡住有色材料12；

在具体实施时，本公开实施例提供的上述显示面板的工作原理可以按照遮挡部的结构分为以下几种情况。
第一种情况：组成遮挡部的遮挡板是采用可旋转方式与盒体固定连接的。
当第二电磁体铁位于反射盒的入光侧，第三电磁铁位于反色盒的背光侧时，当根据对应位置处的显示画面，确定反色盒需要显示遮挡部的入光面的颜色时，第二电压单元向第二电磁铁输出电压，使第二电磁铁对遮挡部中的磁性材料产生吸引力，从而使遮挡部向盒腔的入光面一侧旋转，最终使遮挡部的入光面贴近盒腔的入光面，进而使遮挡部的入光面在入光方向上挡住有色材料；当根据对应位置处的显示画面，确定反色盒需要显示有色材料颜色时，第三电压单元向第三电磁铁输出电压，使第三电磁铁对遮挡部中的磁性材料产生吸引力，从而使遮挡部向盒腔的背光面一侧旋转，最终使遮挡部的入光面远离盒腔的入光面，进而使遮挡部的入光面浸没在有色材料中。
反之，当第二电磁体铁位于反射盒的背光侧，第三电磁铁位于反色盒的入光侧时，当根据对应位置处的显示画面，确定反色盒需要显示遮挡部的入光面的颜色时，第二电压单元向第二电磁铁输出电压，使第二电磁铁对遮挡部中的磁性材料产生排斥力，从而使遮挡部向盒腔的入光面一侧旋转，最终 使遮挡部的入光面贴近盒腔的入光面，进而使遮挡部的入光面在入光方向上挡住有色材料；当根据对应位置处的显示画面，确定反色盒需要显示有色材料颜色时，第三电压单元向第三电磁铁输出电压，使第三电磁铁对遮挡部中的磁性材料产生排斥力，从而使遮挡部向盒腔的背光面一侧旋转，最终使遮挡部的入光面远离盒腔的入光面，进而使遮挡部的入光面浸没在有色材料中。
第二种情况：遮挡部是一块入光面平行于盒腔的入光面的遮挡板。
当第二电磁体铁位于反射盒的入光侧，第三电磁铁位于反色盒的背光侧时，当根据对应位置处的显示画面，确定反色盒需要显示遮挡部的入光面的颜色时，第二电压单元向第二电磁铁输出电压，使第二电磁铁对遮挡部中的磁性材料产生吸引力，从而使遮挡部向盒腔的入光面一侧平移，最终使遮挡部的入光面贴近盒腔的入光面，进而使遮挡部的入光面在入光方向上挡住有色材料；当根据对应位置处的显示画面，确定反色盒需要显示有色材料颜色时，第三电压单元向第三电磁铁输出电压，使第三电磁铁对遮挡部中的磁性材料产生排斥力，从而使遮挡部向盒腔的背光面一侧平移，最终使遮挡部的入光面远离盒腔的入光面，进而使遮挡部的入光面浸没在有色材料中。
反之，当第二电磁体铁位于反射盒的背光侧，第三电磁铁位于反色盒的入光侧时，当根据对应位置处的显示画面，确定反色盒需要显示遮挡部的入光面的颜色时，第二电压单元向第二电磁铁输出电压，使第二电磁铁对遮挡部中的磁性材料产生排斥力，从而使遮挡部向盒腔的入光面一侧平移，最终使遮挡部的入光面贴近盒腔的入光面，进而使遮挡部的入光面在入光方向上挡住有色材料；当根据对应位置处的显示画面，确定反色盒需要显示有色材料颜色时，第三电压单元向第三电磁铁输出电压，使第三电磁铁对遮挡部中的磁性材料产生排斥力，从而使遮挡部向盒腔的背光面一侧平移，最终使遮挡部的入光面远离盒腔的入光面，进而使遮挡部的入光面浸没在有色材料中。
第三种情况：遮挡部是一块入光面平行于盒腔的入光面的遮挡板，且该遮挡板的入光面的预设区域与盒体的入光面弹性连接，且在自然状态下该遮挡板的入光面紧贴盒腔的入光面。
当第二电磁体铁位于反射盒的入光侧，第三电磁铁位于反色盒的背光侧时，当根据对应位置处的显示画面，确定反色盒需要显示遮挡部的入光面的 颜色时，第二电压单元向第二电磁铁输出电压，该电压最好为0伏，这样遮挡部恢复自然状态，从而使遮挡部的入光面贴近盒腔的入光面，进而使遮挡部的入光面在入光方向上挡住有色材料；当根据对应位置处的显示画面，确定反色盒需要显示有色材料颜色时，第三电压单元向第三电磁铁输出电压，使第三电磁铁对遮挡部中的磁性材料产生吸引力，从而使遮挡部向盒腔的背光面一侧平移，最终使遮挡部的入光面远离盒腔的入光面，进而使遮挡部的入光面浸没在有色材料中。
反之，当第二电磁体铁位于反射盒的背光侧，第三电磁铁位于反色盒的入光侧，当根据对应位置处的显示画面，确定反色盒需要显示遮挡部的入光面的颜色时，第二电压单元向第二电磁铁输出电压，该电压最好为0伏，这样遮挡部恢复自然状态，从而使遮挡部的入光面贴近盒腔的入光面，进而使遮挡部的入光面在入光方向上挡住有色材料；当根据对应位置处的显示画面，确定反色盒需要显示有色材料颜色时，第三电压单元向第三电磁铁输出电压，使第三电磁铁对遮挡部中的磁性材料产生排斥力，从而使遮挡部向盒腔的背光面一侧平移，最终使遮挡部的入光面远离盒腔的入光面，进而使遮挡部的入光面浸没在有色材料中。
可选地，针对第一种情况和第二种情况的显示面板，第二电压单元在第二电磁铁控制遮挡部的入光面贴近盒腔的入光面之后停止向第二电磁铁输出电压；和/或，第三电压单元在第三电磁铁控制遮挡部的入光面远离盒腔的入光面之后停止向第三电磁铁输出电压。这样显示面板只有在各子像素需要变换显示颜色时才通电，因此可以达到节能的效果。
可选地，在本公开实施例提供的上述显示面板中，第二电压单元还用于，根据对应位置处的显示画面，确定反色盒需要显示有色材料颜色时，向第二电磁铁输出电压，使第二电磁铁控制遮挡部的入光面浸没在有色材料中；第三电压单元还用于，当根据对应位置处的显示画面，确定反色盒需要显示遮挡部的入光面的颜色时，向第三电磁铁输出电压，使第三电磁铁控制遮挡部的入光面在入光方向上挡住有色材料。即第二电压单元既可控制第二电磁铁使遮挡部的入光面贴近盒腔的入光面，也可控制第二电磁铁使遮挡部的入光面远离盒腔的入光面；同理，第三电压单元也既可控制第三电磁铁使遮挡部 的入光面远离盒腔的入光面，也可控制第三电磁铁使遮挡部的入光面贴近盒腔的入光面。从而利用两块电磁铁同时控制遮挡部的移动，使遮挡部的入光面能够最大程度的贴近盒腔的入光面或远离盒腔的入光面，进而可以达到最佳的显示效果。
基于同一发明构思，本公开实施例还提供了一种上述任一种显示面板的显示方法，如图5所示，包括：
S501、接收显示画面信息；
S502、根据对应位置处的显示画面信息控制对应的反色盒中的遮挡部的入光面与盒腔的入光面的相对位置，使反色盒显示遮挡部的入光面的颜色或有色材料的颜色。
基于同一发明构思，发明实施例还提供了一种显示装置，包括本公开实施例提供的上述任一种显示面板。由于该显示装置解决问题的原理与前述一种显示面板相似，因此该显示装置的实施可以参见前述显示面板的实施，重复之处不再赘述。
本公开实施例提供的显示面板，包括多个像素，各像素包括至少一个子像素；其中，各子像素包括反色盒和用于控制反色盒所显示的颜色的控制部；反色盒包括：具有盒腔的盒体、以及密封于盒腔中的有色材料和遮挡部，盒体的入光面为透明材料，遮挡部的入光面具有预设的基底颜色；控制部用于，在有外界光的情况下，根据对应位置处的显示画面控制对应的反色盒中的遮挡部的入光面与盒腔的入光面的相对位置，使反色盒显示遮挡部的入光面的颜色或有色材料的颜色。这样在有外界光照射的情况下，通过控制部控制反色盒的反射颜色实现显示面板的画面显示。将上述显示显示面板应用于广告牌，不仅可以避免人工更换广告牌内容所带来的不便，并且由于该显示装置通过外界光反射来实现显示，因此与现有的通过发光源直接进行显示的显示装置相比，在白天户外进行显示时，视觉效果更佳，并且外界光越强，视觉效果越佳。
显然，本领域的技术人员可以对本公开进行各种改动和变型而不脱离本公开的精神和范围。这样，倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
