Description

一种基于五种专用色的电子墨水屏及其显色方法
技术领域
本发明涉及电子墨水屏技术领域，具体涉及一种基于五种专用色的电子墨水屏及其显色方法。
背景技术
电子墨水屏基于省电、护眼的特点得到迅速的发展，但是普遍都是黑白两种颜色，这就制约了电子墨水屏往多媒体的发展。
当前电子墨水屏已经出现了彩色屏幕，但是因为彩色屏幕颜色过多，从而导致驱动电路设计复杂，刷新率降低，电子纸使用过程中的卡顿感会更加明显。考虑到上述的黑白墨水屏和多彩墨水屏的不足，如果可以利用两者的优点，为特定的场景提供对应的专有颜色屏幕，会有很大的实用价值。
发明内容
针对现有技术的不足，本发明旨在提供一种基于五种专用色的电子墨水屏及其显色方法。
为了实现上述目的，本发明采用如下技术方案：
一种基于五种专用色的电子墨水屏，包括多个像素块，每个像素块中容置有四个微胶囊或微杯，每个微胶囊或微杯中均装载有两种不同颜色的带电染色粒子；其中，所有微胶囊或微杯中均装载有带专用色一的带电染色粒子，并且各个微胶囊或微杯中分别装载有带专用色二、专用色三、专用色四、专用色五的带电染色粒子；同一个微胶囊或微杯中，相同颜色的带电染色粒子电性相同，不同颜色的带电染色粒子电性不同；在同一显色时间内仅有带专用色二、专用色三、专用色四、专用色五的带电染色粒子中的一种位于所在微胶囊或微杯的顶部。
进一步地，一个像素块中的四个微胶囊或微杯呈”||||“形状或者“田”字型排布。
进一步地，各个微胶囊或微杯中的带专用色一的带电染色粒子均带正电荷，其他颜色的带电染色粒子均带负电荷。
进一步地，像素块中各个微胶囊或微杯分别采用不同的驱动电路单独进行驱动控制。
本发明公开了一种利用上述电子墨水屏的显色方法，具体过程为：
令各个微胶囊或微杯中的带专用色一的粒子带上正电荷或负电荷，并且令同一微胶囊或微杯中的另一种颜色的带电染色粒子带上相反电性的电荷；
按照显示界面的显色要求，获取每个像素块上需要展示的颜色；
根据需要展示的颜色，给对应像素块上的各个微胶囊或微杯给予相应的驱动电压进行驱动，使其内部形成电场，从而使各个微胶囊或微杯中需要参与显色的带电染色粒子移动至所在微胶囊或微杯的顶部，不需要参与显色的带电染色粒子位于所在微胶囊或微杯的底部。
本发明的有益效果在于：本发明采用四个微胶囊或微杯构成一个像素块，每个微胶囊或微杯中仅有带两种颜色的带电染色粒子，驱动时只需要驱动其中一种需要参与显色的带电染色粒子移动至微胶囊或微杯的顶部即可，由此实现了五种专用色的显色，驱动电路简单，刷新效率高，显色明亮，尤其适合于仅需几种特定专用色就可以满足显示需求的场合。
附图说明
图1为本发明实施例1中其中一种微胶囊或微杯排布方式的像素块结构示意图；
图2为本发明实施例1中另一种微胶囊或微杯排布方式的像素块结构示意图。
具体实施方式
以下将结合附图对本发明作进一步的描述，需要说明的是，本实施例以本技术方案为前提，给出了详细的实施方式和具体的操作过程，但本发明的保护范围并不限于本实施例。
实施例1
本实施例提供一种基于五种专用色的电子墨水屏，如图1-2所示，包括多个像素块1(图中仅显示一个像素块的结构)，每个像素块1中容置有四个微胶囊或微杯2、3、4、5，每个微胶囊或微杯2、3、4、5中均装载有两种不同颜色的带电染色粒子；其中，所有微胶囊或微杯2、3、4、5中均装载有带专用色一的带电染色粒子6，并且各个微胶囊或微杯2、3、4、5中分别装载有带专用色二、专用色三、专用色四、专用色五的带电染色粒子7、8、9、10；同一个微胶囊或微杯中，相同颜色的带电染色粒子电性相同，不同颜色的带电染色粒子电性不同。
需要说明的是，图1-2所示为像素块顶部视觉的平面示意图，图示正面为顶面一侧。
需要说明的是，在所有微胶囊或微杯中都存在的专用色一是基底色，可以是常见的背景色(如普通墨水屏中的基底色白色或者护眼墨水屏中的基底色绿色等)，也可以是显色中需要占比最多的颜色，具体根据应用场景而定。专用色二、三、四、五可以根据实际的应用需求而定，例如在智慧课堂应用中，专用色二、三、四、五可以分别为黑色、红色、绿色、蓝色。
需要说明的是，微胶囊的具体结构可以参考中国专利申请CN103091926A中的相关描述，微杯的结构可以参考中国专利CN1246730C中的相关描述，此处不再赘述。
需要说明的是，一个像素块1中的四个微胶囊或微杯2、3、4、5的排布方式可以不作限制，呈”||||“形状(如图1所示)或者“田”字型排布(如图2所示)为较优的选择。
在本实施例中，各个微胶囊或微杯2、3、4、5中的带专用色一的带电染色粒子6均带正电荷，其他颜色的带电染色粒子7、8、9、10均带负电荷。
需要说明的是，各个微胶囊或微杯2、3、4、5的体积可以相同，这样专用色一的最大显色比例为100％，专用色二、三、四、五四种颜色的显色比例均为25％。也可以根据各种专用色显色比例的需要，将相应的微胶囊或微杯制作成相应的体积大小，使各个专用色的显示面积可以满足相应的显色比例需求。显色比例即是指某一种专用色显示时，其所在微胶囊或微杯顶部的面积占像素块顶部总面积的比例。
进一步地，在本实施例中，像素块中各个微胶囊或微杯分别采用不同的驱动电路单独进行驱动控制。这样可以根据显色需求，分别对各个微胶囊或微杯施加相应的驱动电压，使其内部形成电场，驱动需要参与显色的带电染色粒子移动至所在微胶囊或微杯的顶部，不需要参与显色的带电染色粒子位于微胶囊或微杯的底部。从而可控制像素块显色为红白白白白组合的红色、白白白白白组合的白色、白白白白黑组合的黑色、绿白白白白组合的绿色、蓝白白白白组成的蓝色。这种驱动方式和黑白驱动差异不大，刷新效率高，显色明亮。
实施例2
本实施例提供一种利用实施例1所述电子墨水屏的显色方法，具体过程为：
令各个微胶囊或微杯中的带专用色一的粒子带上正电荷或负电荷，并且令同一微胶囊或微杯中的另一种颜色的带电染色粒子带上相反电性的电荷。
按照显示界面的显色要求，获取每个像素块上需要展示的颜色。
根据需要展示的颜色，给对应像素块上的各个微胶囊或微杯给予相应的驱动电压进行驱动，使其内部形成电场，从而使各个微胶囊或微杯中需要参与显色的带电染色粒子移动至所在微胶囊或微杯的顶部，不需要参与显色的带电染色粒子位于所在微胶囊或微杯的底部。
需要说明的是，虽然每个像素块中除专用色一外其他专用色只有约1/4的显色比例，其他色为专用色一，但仍然具备良好的显色能力。虽然其他专用色会存在微小的颗粒感，但是对使用体验影响并不大。
对于本领域的技术人员来说，可以根据以上的技术方案和构思，给出各种相应的改变和变形，而所有的这些改变和变形，都应该包括在本发明权利要求的保护范围之内。
