具体实施方式
为使本领域技术人员更好地理解本发明的技术方案，下面结合附图和具体实施方式对本发明作进一步详细描述。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”、“一”或者“该”等类似词语也不表示数量限制，而是表示存在至少一个。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
如图1所示，一种示例性的彩色电子纸包括多个微胶囊10，以及设置在多个微胶囊中的每个的两相对侧的第一电极11和第二电极12；所述多个微胶囊10中的每个包括：三种颜色带电粒子；三种颜色的带电粒子分别为白色(White)粒子、黑色(Black)粒子以及彩色粒子。彩色粒子包括但不限于黄色(Yellow)粒子，在本公开实施例中以彩色粒子为黄色粒子103为例进行说明。黑色粒子101与白色粒子102所带电荷的电性相反，与黄色粒子103所点电荷的电性相同，且黑色粒子101的电荷质量比大于黄色粒子103的电荷质量比。
本领域技术人员应当理解的是，由于黑色粒子101和黄色粒子103的所带电荷的电性相同，且黑色粒子101的电荷质量比大于黄色粒子103的电荷质量比，因此在给第一电极11和第二电极12施加电压产生电场，黑色粒子101的移动速度大于黄色粒子103的移动速度。
在此待要说明的是，第一电极11和第二电极12在微胶囊10相对两侧的位置不进行限定；可以是第一电极11较第二电极12靠近显示侧，也即第一基底所在侧为显示侧；也可以是，第二电极12较第一电极11靠近显示侧，也即第二基底所在侧为显示侧。在本公开实施例中，以图1中所示的第二电 极12较第一电极11靠近显示侧为例进行说明。
此外，各个微胶囊10对应的第二电极12可以电连接在一起，在此情况下，每个第二电极12所施加的电压信号相同，此时第二电极12可以称之为公共电极(也可以称之为Vcom电极)；当然，各个微胶囊10对应的第二电极12也可以不电连接在一起，在此情况下，各个第二电极12所施加的电压信号可以相同，也可以不相同。在一些实施例中第二电极12可以接地(也即0V电压)。
对于黑色粒子101、白色粒子102、黄色粒子103所带电荷的电性不进行限制，可以是黑色粒子101和黄色粒子103带正电荷，白色粒子102带负电荷，也可以是黑色粒子101和黄色粒子103带负电荷，白色粒子102带正电荷；在本公开实施例中，以黑色粒子101和黄色粒子103带正电荷，白色粒子102带负电荷为例进行说明。
在现有技术中，能够显示黑/白/黄图像的画面的彩色电子纸属于亮色类电子纸，颜色鲜艳，得到广大消费者的青睐，但是发明人发现，在高温情况下，该种电子纸出现显示不清晰的问题，特别是在，白底黑色画面(例如白底黑字)显示时，显示黑色部分，再显示白色部分，导致白色部分的白色粒子102干扰黑色部分中的黑色粒子101的显示，造成黑色部分图像显示不清晰。
对此在本公开实施例中提供以下技术方案。
第一方面，针对图1所示的彩色电子纸，如图2和3所示，本公开实施例提供一种彩色电子纸的驱动方法，该方法包括：
S100、根据待显示图像，向待显示白色的微胶囊10的第一电极11施加第一驱动信号01，向待显示黑色的微胶囊10的第一电极11施加第二驱动信号02。
其中，第一驱动信号01包括在显示阶段T1向待显示白色的微胶囊10第一电极11施加的第一子驱动信号011，第一子驱动信号011用于驱动待显示白色的微胶囊10中的白色粒子102相较黑色粒子101和黄色粒子103靠 近显示侧；也即，将第一子驱动信号011施加给待待显示白色的微胶囊10的第一电极11，此时该第一电极11和第二电极12产生电场，驱动白色粒子102向第二电极12侧移动，以使该微胶囊10靠近显示侧的侧面显示白色，从而实现待显示图像的白色部分的显示。应当理解的是，由于白色粒子102带负电，此时给第一电极11所施加的第一子驱动信号011应为一负电压信号，且电压值应当满足能够带动白色粒子102进行移动。
第二驱动信号02包括在显示阶段T1向待显示黑色的微胶囊10第一电极11施加的第二子驱动信号012，第二子驱动信号012用于驱动待显示黑色的微胶囊10中的黑色粒子101相较白色粒子102和黄色粒子103靠近显示侧；也即，将第二子驱动信号012施加给待显示黑色的微胶囊10的第一电极11，该第一电极11和第二电极12产生电场，驱动黑色粒子101向第二电极12侧移动，以使该微胶囊10靠近显示侧的侧面显示黑色，从而实现待显示图像的白黑色部分的显示。应当理解的是，由于黑色粒子101带负电，此时给第一电极11所施加的第二子驱动信号012应为一正电压信号，且电压值应当满足能够带动黑色粒子101进行移动。
特别的是，在本公开实施例中第二子驱动信号012的有效电压的起始时间不早于第一子驱动信号011的有效电压的终止时间。也就是说，在显示阶段T1，彩色电子纸先对待显示图像的白色部分进行显示，显示完成之后再对黑色部分进行显示，从而的有效的避免了现有技术中显示黑色部分再显示白色部分，造成黑色部分被白色部分干扰的，而导致黑色显示不清晰的问题。
在一些实施例中，第二子驱动信号012的有效电压起始时间为第一子驱动信号011的有效电压的终止时间。也就是说，在彩色电子纸的待显示图像的白色部分显示完成即刻显示黑色部分，从而有效的提高刷新频率，以使彩色电子纸的显示效果更佳。
当然，第二子驱动信号012的起始时间只要不早于第一子驱动信号011的终止时间就可以，例如，第二驱动信号02还可以包括在显示阶段T1向第一电极11写入的零电压信号，该零电压信号位于第二子驱动信号012的起始时间之前，此种情况下，待显示画面的白色部分显示完成之后间隔一定的 时间才会显示黑色部分，所间隔的时间则取决于第二驱动信号02在显示阶段T1的第二子驱动信号012之前的零电压信号所的持续的时间。
在一些实施例中，如图4所示，第二驱动信号02还包括第三子驱动信号013，第三子驱动信号013用于在第二子驱动信号012驱动待显示黑色的微胶囊10显示黑色之后，再次给驱动待显示黑色的微胶囊10中的黑色粒子101相对于白色粒子102和黄色粒子103靠近显示侧。这样一来，也就是说，在对待显示画面的进行显示时，两次驱动待显示黑色的微胶囊10中的黑色粒子101移动，从而更有效的避免了黑色部分显示不清晰的问题。
在此待要说明的是，第二驱动信号02的第二子驱动信号012和第三子驱动信号013之间通常包括一段时间的零电压驱动信号(也即0V电压)，也就是说，在待显示黑色的微胶囊10的第一电极11施加第二子驱动信号012，微胶囊10中的黑色粒子101相对白色粒子102和黄色粒子103靠近显示侧后，停止给这部分微胶囊10的第一电极11施加电压，这样一来，再次给这部分微胶囊10的第一电极11施加第三子驱动信号013后，对黑色粒子101再次驱动，以尽可能保证所有的微胶囊10中的所有黑色粒子101均相对白色粒子102和黄色粒子103靠近显示侧，此时则大大降低了黑色粒子101被白色粒子102干扰的可能。
其中，第三子驱动信号013与第二子驱动信号012的有效电压值和有效电压的持续时间均相同，从而保证待显示黑色的微胶囊10显示的黑色更加均匀。
在一些实施例中，彩色电子纸的驱动方法不仅包括上述步骤，还包括：向待显示黄色的微胶囊10的第一电极11施加第三驱动信号03的步骤。其中，如图5所示，第三驱动信号03包括在显示阶段T1为第一电极11施加的第四子驱动信号014，第四子驱动信号014用于驱动待显示黄色的微胶囊10中的黄色粒子103相对白色粒子102和黑色粒子101靠近显示侧，以使黄色部分对应的微胶囊10显示黄色。
在一些实施例中，第四子驱动信号014包括至少一个脉冲重复单元 0141；每个脉冲重复单元0141包括依次施加在第一电极的第一电压V1、零电压(0V)和第二电压V2；其中，第一电压V1用于驱动白色粒子102相对黑色粒子101和黄色粒子103靠近显示侧，第二电压V2用于驱动黄色粒子103相对白色粒子102和黑色粒子101靠近显示侧。
在此待要说明的是，由于黄色粒子103的电荷质量比小于黑色粒子101的电荷质量比，因此驱动黄色粒子103移动的第二电压的电压值，要小于第二子驱动信号012的有效电压的电压值，故在本公开实施例中的第四子驱动信号014包括多个脉冲重复单元0141，以使待显示画面的黄色部分显示均匀。
在驱动彩色电子纸待显示黄色的微胶囊10时，之所以在给第一电极11施加上第二电压之前，先给第一电极11施加第一电压的原因是，先通过第一电压驱动白色粒子102移动至相对黑色粒子101和黄色粒子103靠近显示侧，之后通过零电压让黄色部分对应微胶囊10静置，以使带显示画面的黄色部分显示白色，最后再给第一电极11施加第二电压，驱动黄色粒子103移动至对白色粒子102和黑色粒子101靠近显示侧，从而使得和黄色粒子103相邻的是白色粒子102所在层，如此，通过白色粒子102缓解黄色粒子103显示黄色时，黄色过于鲜亮的问题，以使黄色部分显示更加温和。
在一些实施例中，如图5所示，第四子驱动信号014还包括两个重复脉冲单元014之间的零电压驱动信号(也即0V电压)，也就是说，每给待显示画面的黄色部分所对应的第一电极11施加脉冲重复单元0141的第二电压后，再给该第一电极11施加一零电压，以使该黄色部分的微胶囊10中的各个粒子静置，最后黄色部分所对应的第一电极11施加脉冲重复单元0141信号，以使黄色部分显示更加均匀。
在一些实施例中，第三驱动信号03还包括给待显示彩色的微胶囊10的第一电极11施加第二子驱动信号012时，给黄色部分所对应的第一电极11施加的第五子驱动信号，如图6所示，第五子驱动信号015用于在显示阶段T1待显示黑色的微胶囊10显示黑色的同时，驱动黄色部分的微胶囊10中黑色粒子101相对黄色粒子103和白色粒子102靠近显示侧，简言之，也就 是在显示阶段T1待显示黄色的微胶囊10在显示黄色之前先显示黑色，这样一来，可以避免黄底黑字画面中的黑色显示不清晰的问题。
在一些实施例中，如图7所示，彩色电子纸的驱动方法还包括在显示阶段T1之前的平衡阶段T2，第三驱动信号03包括第四子驱动信号014，第四子驱动信号014包括至少一个脉冲重复单元0141，每个脉冲重复单元0141包括依次施加在第一电压V1、零电压(0V)和第二电压V2时，第三驱动信号03还包括在平衡阶段T2向第一电极11施加的第六子驱动信号016；其中，第六子驱动信号016的有效电压的电性与第一电压V1的电性相同；第六子驱动信号016的有效电压的绝对值与施加有效电压的时间的乘积等于第四子驱动信号014中的第一电压的绝对值与施加第一电压的时间的乘积和第二电压的绝对值与施加第二电压的时间的乘积之差。
由于在本公开实施例中是以第一电压为负电压、第二电压为负电压为例进行说明的，因此，第六子驱动信号016的有效电压的电性为负；应当理解的是，若第一电压为正电压，那么第六子驱动信号016的有效电压的电性则为正。
由于在本公开实施例中，在显示阶段T1之前增加平衡阶段T2，第三驱动信号03在平衡阶段T2施加给第一电极11的第六子驱动信号016的有效电压的绝对值与施加有效电压的时间的乘积等于第四子驱动信号014中的第一电压的绝对值与施加第一电压的时间的乘积和第二电压的绝对值与施加第二电压的时间的乘积之差，这样一来，可以平衡第三驱动信号03在显示阶段T1的电压，避免待显示画面中待显示黄色的微胶囊10中白色粒子102、黑色粒子101、黄色粒子103，因电场不平衡而产生内建电场，进而导致极化。
在本公开实施例中，第六子驱动信号016的有效电压可以与第一电压相等，当然也可以不相等，在图7中是以第六子驱动信号016的有效电压与第一电压相等为例进行示意的。
在本公开实施例中，第六子驱动信号016的有效电压与第一电压相等， 这样可以进一步平衡第三驱动信号03在显示阶段T1的电压，维持正负电压的时间总和，更有效的避免待显示画面中待显示黄色的微胶囊10中的白色粒子102、黑色粒子101、黄色粒子103，因电场不平衡而产生内建电场，进而导致极化。
如图7所示，在向待显示白色的微胶囊10的第一电极11施加的第一驱动信号01包括第一子驱动信号011，向待显示黑色的微胶囊10的一电极11施加的第二驱动信号02包括第二子驱动信号012时，第一驱动信号01包括在平衡阶段T2给第一电极11施加的第七子驱动信号017，第二驱动信号02包括在平衡阶段T2给第一电极11施加的第八子驱动信号018；其中，第七子驱动信号017的有效电压的电性与第一子驱动信号011的有效电压的电性相反；第八子驱动信号018的有效电压的电性与第二子驱动信号012的有效电压的电性相反；而且，第一驱动信号01在平衡阶段T2的有效电压(也即第七子驱动信号017的有效电压)的绝对值与施加有效电压的时间乘积等于在显示阶段T1施加有效电压的绝对值与施加有效电压时间的乘积；第二驱动信号02在平衡阶段T2的有效电压(第八子驱动信号018的有效电压)的绝对值与施加有效电压的时间乘积等于在显示阶段T1施加有效电压的绝对值与施加有效电压时间的乘积。
第一驱动信号01在显示阶段T1的有效电压的为正电压的情况，第一驱动信号01在平衡阶段T2的有效电压则为负电压；第一驱动信号01在显示阶段T1的有效电压的为负电压的情况，第一驱动信号01在平衡阶段T2的有效电压则为正电压；对于第二驱动信号02在平衡阶段T2和显示阶段T1的电性关系可以参考第一驱动信号01，故在此不再赘述。
在本公开实施例中，在显示阶段T1之前增加平衡阶段T2，第一驱动信号01在平衡阶段T2的有效电压(也即第七子驱动信号017的有效电压)的绝对值与施加有效电压的时间乘积等于在显示阶段T1施加有效电压的绝对值与施加有效电压时间的乘积；第二驱动信号02在平衡阶段T2的有效电压(第八子驱动信号018的有效电压)的绝对值与施加有效电压的时间乘积等于在显示阶段T1施加有效电压的绝对值与施加有效电压时间的乘积，从而 有效的避免了待显示画面中待显示黑色的微胶囊10和白色的微胶囊10中白色粒子102、黑色粒子101、黄色粒子103，因电场不平衡而产生内建电场，进而导致极化。
此处，第一驱动信号01在显示阶段T1和平衡阶段T2的有效电压的绝对值可以相等，也可以不相等；同理，第二驱动信号02也是如此，附图7中是以第一驱动信号01、第二驱动信号02均在显示阶段T1和平衡阶段T2的有效电压的绝对值相等为例进行示意的。
在此还待要说明的是，附图7中的第二驱动信号02在平衡阶段T2的第八子驱动信号018是按照第二驱动信号02在显示阶段T1仅包括第二子驱动信号012为例进行示意的，若在显示阶段T1第二驱动信号02还包括第三子驱动信号013，此时应按照上述平衡阶段T2与现实阶段的电压关系对平衡阶段T2的第八子驱动信号018的波形进行调整。
在本公开实施例中，第一驱动信号01、第二驱动信号02均在显示阶段T1和平衡阶段T2的有效电压的绝对值相等，这样可以进一步平衡第一驱动信号01和第二驱动信号02在显示阶段T1的电压，维持正负电压的时间总和，更有效的避免待显示画面中待显示白色的微胶囊10和待显示黑色的微胶囊10中的白色粒子102、黑色粒子101、黄色粒子103，因电场不平衡而产生内建电场，进而导致极化。
在一些实施例中，如图8所示，在显示阶段T1和平衡阶段T2之间还包括均匀化阶段T3(Shaking),第一驱动信号01、第二驱动信号02、第三驱动信号03分别包括在均匀化阶段T3的第九子驱动信号019、第十子驱动信号020、第十一子驱动信号021；其中，第九子驱动信号019、第十子驱动信号020、第十一子驱动信号021均包括正负电压交替的脉冲信号。
此处，对于第九子驱动信号019、第十子驱动信号020、第十一驱子动信号021的脉冲信号的个数均不做限定，可以根据待要进行具体设置。附图8中只是以包含4个脉冲信号为例进行示意的。
在本公开实施例中，由于在显示阶段T1和平衡阶段T2之间增加均匀化 阶段T3，且第一驱动信号01、第二驱动信号02、第三驱动信号03分别包括在均匀化阶段T3的第九子驱动信号019、第十子驱动信号020、第十一子驱动信号021；而第九子驱动信号019、第十子驱动信号020、第十一子驱动信号021均包括正负电压交替的脉冲信号，因此每个微胶囊10中白色粒子102、黑色粒子101、黄色粒子103在均匀化阶段T3充分分开、混合均匀，便于在显示阶段T1快速精准地移动，从而可以实现更好的显示效果。
在一些实施例中，彩色电子纸的驱动方法还包括检测环境温度，并判断环境温度是否大于预设值，当环境温度大于或者等于预设值时，采用根据待显示图像，给所述待显示图像中待显示白色的微胶囊10的第一电极11施加第一驱动信号01，待显示黑色微胶囊10的第一电极11施加第二驱动信号02；其中，第一驱动信号01包括在显示阶段T1向待显示白色的微胶囊10的第一电极11施加的第一子驱动信号011，第一子驱动信号011用于驱动待显示白色的微胶囊10中的白色粒子102相较黑色粒子101和黄色粒子103靠近显示侧；第二驱动信号02包括在显示阶段T1向待显示黑色的微胶囊10的第一电极11施加的第二子驱动信号012，第二子驱动信号012用于驱动待显示黑色的微胶囊10中的黑色粒子101相较白色粒子102和黄色粒子103靠近显示侧；其中，第二子驱动信号012的起始时间不早于第一子驱动信号011的终止时间。也就是说，在显示阶段T1，彩色电子纸先对待显示图像的白色部分进行显示，显示完成之后再对黑色部分进行显示。
当环境温度大于或者等于预设值时，则给白色部分所对应的第一电极11施加的第一子驱动信号011的起始时间不早于第二子驱动信号012的终止时间。也就是说，在显示阶段T1，彩色电子纸先对待显示图像的黑色部分进行显示，显示完成之后再对白色部分进行显示。
其中，环境温度的预设值包括但不限于40℃。
第二方面，如图9所示，本公开实施例提供一种彩色电子纸，多个微胶囊10，以及设置在多个微胶囊中的每个的两相对侧的第一电极11和第二电极12；所述多个微胶囊10中的每个包括：包括三种颜色带电粒子；三种颜色的带电粒子分别为白色(White)粒子、黑色(Black)粒子，以及彩色粒子。 彩色粒子包括但不限于黄色(Yellow)粒子，在本公开实施例中以彩色粒子为黄色粒子103为例进行说明。黑色粒子101与白色粒子102所带电荷的电性相反，与黄色粒子103所点电荷的电性相同，且黑色粒子101的电荷质量比大于黄色粒子103的电荷质量比。
本公开实施例中的彩色电子纸还包括处理器20，该处理器根据待显示图像，向待显示图像中待显示白色的微胶囊10的第一电极11施加第一驱动信号01，待显示黑色的微胶囊10的第一电极11施加第二驱动信号02；其中，第一驱动信号01和第二驱动信号02可以为上述驱动方法中的驱动信号，在此不再重复描述。这样一来，本公开实施例中的彩色电子纸，在显示阶段T1，先驱动待显示图像的待显示白色的微胶囊10进行显示，显示完成之后再驱动待显示图像的待显示黑色的微胶囊10进行显示，从而的有效的避免了现有技术中显示黑色部分再显示白色部分，造成黑色部分被白色部分干扰的，而导致黑色显示不清晰的问题。
在本公开实施例中处理器还用于为待显示画面中的待显示黄色的微胶囊的第一电极11施加第三驱动信号03，其中第三驱动信号03可以为上述驱动方法中的任意一种，故在此不再重复描述。
在一些实施例中，如图10所示，彩色电子纸还包括温度传感器30，该温度传感器用于检测环境温度，并反馈给处理器，以使处理器根据环境温度对第一驱动信号01、第二驱动信号02、第三驱动信号03的驱动波形进行调整。
在此待要说明的是，对于处理器的解释及效果可以参考彩色电子纸的驱动方法，在此不再重复描述。
