[0042] 图3是将图2中的其中2个点阵160和170放大后的示意图,其中左边虚线方框是点阵160,右边虚线方框是点阵170,而180是挡墙。 [0042] FIG. 3 is a schematic diagram in FIG. 2 in which the two enlarged lattice 160 and 170, wherein the left block is a dot dashed line 160, to the right of the broken line is a dot matrix block 170, while 180 is a retaining wall. 每一个点阵都由若干个次点阵组成,这里举的例子是每个点阵由4个次点阵组成。 Each dot consists of several sub-dot matrix, each of the examples cited here are four sub-lattice of dot matrix. 每个次点阵上是不同的彩色微胶囊。 Different colored microcapsules on each sub lattice. 图3只是说明显示装置的平面示意图,实际的设计每一个点阵不一定只是采用图中的4个次点阵,且每一个次点阵上不一定是9个微胶囊,具体的次点阵数目和微胶囊数目根据实际的设计而定。 Figure 3 only shows a schematic plan view of a display device, the actual design of each dot is not necessarily just a matrix with four times in the figure, and each time a dot is not necessarily a microcapsule 9, specific sub lattice the number and the number of microcapsules depends on the actual design.

[0043] 每个点阵的大小与整个显示装置的显示面积,及使用时观察的距离都有关系,而且还与彩色微胶囊的大小有关,经研究表明,单个点阵的平面尺寸应在I 一20000微米的范围内,优选50-1500微米,更优选100-800微米,最优选150-300微米。 [0043] The display size of each dot of the entire display device, and the distance has a relationship observed when using, but also on the size of the color microcapsules, the study showed that the size of a single lattice plane shall be I within a range of 20,000 microns, preferably 50-1500 micron, more preferably 100-800 microns, and most preferably 150-300 micrometers.

[0049] 本发明以R/W (红/白)、G/W (绿/白)、B/W (蓝/白)和K/W (黑/白)电泳微胶囊的组合,即4个次点阵,为例说明颜色的驱动方法。 The present invention in R / W (red / white), G / W (green / white), B / W (blue / white) / W (black / white) composition electrophoretic microcapsules [0049] and K, i.e., 4 lattice times, as an example of the driving method of color. 将红/白微胶囊驱动到红色,将绿/白微胶囊驱动到白色,将黄/白微胶囊驱动到白色,可以显示出红色,而可以调节黑/白微胶囊的灰度来调节整个红色的亮度值;同样,调出绿色与蓝色;将全部微胶囊驱动到白色,则显示白色,将全部微胶囊驱动白色的相反状态,则显示黑色。 The red / white microcapsule to drive red, green driving / white microcapsule white, the driving yellow / white microcapsule white, red can be shown, but may be adjusted gray black / white microcapsule is adjusted throughout the red luminance value; Similarly, the green and blue tone; microcapsules to drive all white, the white is displayed, all the microcapsules is opposite to the driving state of the white, black is displayed. 通过精确控制每个次点阵电极的驱动电压大小或驱动时间、或同时控制电压大小和驱动时间,可以实现次电极对应的彩色微胶囊部分的不同颜色灰度的变化,如通过次电极电压控制,可以让红/白微胶囊实现从红色到白色中的各种灰度,通过这三种微胶囊各种颜色灰度,和黑/白微胶囊来调节颜色的亮度,可以组合出各种颜色,来达到全彩色显示的目的。 Driving time or the driving voltage magnitude of each sub-matrix by precisely controlling the electrodes, while controlling the voltage or the driving time and the size, change the color of different color gradation microcapsules portion corresponding sub-electrodes can be achieved, such as by sub-electrodes voltage control lets red / white microcapsule variety gradation from red to white in by these three colors microcapsules gray, and black / white microcapsule to adjust the brightness of the colors, various colors can be combined to achieve full-color display purposes.
