Abstract

Description

电湿润显示面板及电湿润显示装置 技术领域
本发明涉及显示器领域,特别是涉及一种电湿润显示面板及电湿润显示装置。
背景技术
图1为现有的电湿润显示装置的结构示意图。如图1所示,已知电润湿显示装置10包括电润湿显示面板20与背光模块30。电润湿显示面板20 包括相对设置的两透明基板21、22,且两透明基板21、22之间设置有极性液体23、疏水性介电层24、透明电极25、阻隔壁26以及具有不同颜色的油墨层27(非极性液体) 例如红色油墨27R、绿色油墨27G 与蓝色油墨27B。当电压源28 施加电压于透明电极25 与具极性的水溶液23 之间时,可调整疏水性介电层24与具极性的水溶液23之间的表面张力,进而控制油墨层27的分布位置。由此,背光模块30所发出的白光LW在通过不同的油墨层27会形成具有不同灰阶的红光LR、绿光LG与蓝光LB,而可达到全彩的显示效果。
但是现有的电湿润显示装置中,由于透明电极25均匀设置在透明基板22上,因此在透明电极25上产生的电场会是均匀的电场,因此在连续性地显示具有不同灰阶的画面时,极性液体23与油墨层27会因为受到其它作用力的影响而产生滞留现象(Hysteresis phenomenon)。滞留现象会使的油墨层27实际覆盖于透明基板22的面积与预定覆盖于基板的面积有所偏差。如此一来,将使得电湿润显示装置的灰阶表现不佳,严重影响显示质量。
故,有必要提供一种电湿润显示面板及电湿润显示装置,以解决现有技术所存在的问题。
技术问题
本发明的目的在于提供一种可以防止油墨层产生滞留现象的电湿润显示面板及电湿润显示状;以解决现有的电湿润显示面板及电湿润显示装置由于油墨层的滞留现象造成显示质量较差的技术问题。

本发明的最佳实施方式
以下各实施例的说明是参考附加的图式,用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语,例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等,仅是参考附加图式的方向。因此,使用的方向用语是用以说明及理解本发明,而非用以限制本发明。
在图中,结构相似的单元是以相同标号表示。
请参照图2,图2为本发明的电湿润显示装置的第一优选实施例的结构示意图。本优选实施例的电湿润显示装置200包括光源模块220以及电湿润显示面板210。光源模块220用于提供出射光线,电湿润显示面板210包括第一透明基板211、第二透明基板212以及像素单元,第一透明基板211和第二透明基板212相对设置。
其中像素单元包括第一电极(213A、213B、213C)、第一疏水层214、多个第一阻隔壁215、第二电极216、极性液体217以及多个第一非极性液体(218A、218B、218C)。第一电极213设置在第一透明基板211的像素区内;第一疏水层214设置在第一电极213上;多个第一阻隔壁215设置于第一疏水层214上,并设置在第一透明基板211的像素区的周边;第二电极216设置在第二透明基板212上;极性液体217设置在第二电极216和第一疏水层214之间;多个第一非极性液体218设置于第一疏水层214上,并设置在对应的第一阻隔壁215旁。
在本优选实施例中第一疏水层214上设置有多个用于会聚第一非极性液体218的第一凹陷区域219,第一凹陷区域219紧贴相应的第一阻隔壁215进行设置。
本优选实施例的电湿润显示装置200使用时,根据显示画面的每个像素的色彩灰阶,确定不同灰阶的红光、绿光和蓝光。然后对红光的像素单元对应的第一电极213A、绿光的像素单元对应的第一电极213B以及蓝光的像素单元对应的第一电极213C分别施加相应的电压,第二电极216上施加公共电压。这样可控制第一疏水层214上的红色像素对应的第一非极性液体218A、绿色像素对应的第一非极性液体218B以及蓝色像素对应的第一非极性液体218C的分布,从而使得光源的出射光线通过相应的第一非极性液体(218A、218B、218C)激发出不同灰阶的红光、绿光和蓝光。
如需要发出高灰阶的红光,则可在红光的像素单元对应的第一电极213A上施加较低的电压或不施加电压,这样第一疏水层214上的红色像素对应的第一非极性液体218A均匀的分布在红色像素的像素区上,光源的光线通过该第一非极性液体218A可激发出高灰阶的红光。
如需要发出低灰阶的红光,则可在红光的像素单元对应的第一电极213A上施加较高的电压,这样第一疏水层214上的红色像素对应的第一非极性液体218A会聚集在第一阻隔壁215旁的第一疏水层214的第一凹陷区域219中,这样光源的光线无法通过该第一非极性液体218A或仅少量光线通过第一非极性液体218A,从而光源的光线不可通过该第一非极性液体218A激发出红光或通过该第一非极性液体218A仅激发出少量的红光。
高灰阶或低灰阶的绿光以及高灰阶或低灰阶的蓝光均可以上述方式进行设置。由于第一疏水层214上的第一凹陷区域219的设置,当在第一电极(213A、213B、213C)上施加较高的电压时,第一非极性液体(218A、218B、218C)可很好的会聚于第一凹陷区域219中,从而避免了第一疏水层214上第一非极性液体(218A、218B、218C)的滞留现象的产生。
本优选实施例的电湿润显示装置通过设置在疏水层上的凹陷区域防止非极性液体的滞留现象的产生。
请参照图3,图3为本发明的电湿润显示装置的第二优选实施例的结构。本优选实施例的电湿润显示装置300包括光源模块320以及电湿润显示面板310。光源模块320用于提供出射光线,电湿润显示面板310包括第一透明基板311、第二透明基板312以及像素单元,第一透明基板311和第二透明基板312相对设置。
其中像素单元包括第一电极(313A、313B、313C)、第一疏水层314、多个第一阻隔壁315、第二电极(316A、316B、316C)、极性液体317、多个第一非极性液体(318A、318B、318C)、第二疏水层319、多个第二阻隔壁321以及多个第二非极性液体(322A、322B、322C)。
第一电极(313A、313B、313C)设置在第一透明基板311的像素区内;第一疏水层314设置在第一电极(313A、313B、313C)上;多个第一阻隔壁315设置于第一疏水层314上,并设置在第一透明基板311的像素区的周边;第二电极(316A、316B、316C)设置在第二透明基板312上;多个第一非极性液体(318A、318B、318C)设置于第一疏水层314上,并设置在对应的第一阻隔壁315旁;第二疏水层319设置在第二电极(316A、316B、316C)上;多个第二阻隔壁321设置在第二疏水层319上,并设置在第二透明基板312的像素区的周边;多个第二非极性液体(322A、322B、322C)设置在第二疏水层319上,并设置在对应的第二阻隔壁321旁;极性液体317设置在第一疏水层314和第二疏水层319之间。
在本优选实施例中第一疏水层314上设置有多个用于会聚第一非极性液体(318A、318B、318C)的第一凹陷区域323,第一凹陷区域323紧贴相应的第一阻隔壁315进行设置。同时第二疏水层319上也设置有多个用于会聚第二非极性液体(322A、322B、322C)的第二凹陷区域324,第二凹陷区域324紧贴相应的第二阻隔壁321进行设置。
本优选实施例的电湿润显示装置300使用时,根据显示画面的每个像素的色彩灰阶,确定不同灰阶的红光、绿光和蓝光。然后对红光的像素单元对应的第一电极313A、绿光的像素单元对应的第一电极313B以及蓝光的像素单元对应的第一电极313C分别施加相应的电压。
这样可控制第一疏水层314上的红色像素对应的第一非极性液体318A、绿色像素对应的第一非极性液体318B以及蓝色像素对应的第一非极性液体318C的分布,从而使得光源的出射光线通过相应的第一非极性液体(318A、318B、318C)激发出不同灰阶的红光、绿光和蓝光。
根据显示画面的每个像素的显示亮度,确定不同亮度的红光、绿光和蓝光。然后对红光的像素单元对应的第二电极316A、绿光的像素单元对应的第二电极316B以及蓝光的像素单元对应的第二电极316C分别施加电压。
这样可控制第二疏水层319上的红色像素对应的第二非极性液体322A、绿色像素对应的第二非极性液体322B以及蓝色像素对应的第二非极性液体322C的分布,从而使得光源的出射光线通过相应的第二非极性液体(322A、322B、322C)发生不同的亮度衰减。
这样即可发出高灰阶、低灰阶、高亮度或低亮度的红光。高低灰阶以及高低亮度的绿光、以及高低灰阶以及高低亮度的蓝光均可以上述方式进行设置。由于第一疏水层314的第一凹陷区域323、和第二疏水层319的第二凹陷区域324的设置,当第一电极(313A、313B、313C)上施加较高的电压时,第一非极性液体(318A、318B、318C)可很好的会聚于第一凹陷区域323中,从而避免了第一疏水层314上第一非极性液体(318A、318B、318C)的滞留现象的产生;当第二电极(316A、316B、316C)上施加较高的低压时,第二非极性液体(322A、322B、322C)也可很好的会聚于第二凹陷区域324中,从而避免了第二疏水层319上第二非极性液体(322A、322B、322C)的滞留现象的产生。
本优选实施例的电湿润显示装置通过设置在第一疏水层上的第一凹陷区域以及第二疏水层上的第二凹陷区域,在第一优选实施例的基础上,可方便的对显示灰阶以及显示亮度进行调整。
请参照图4,图4为本发明的电湿润显示装置的第三优选实施例的结构示意图。本优选实施例的电湿润显示装置400包括光源模块420以及电湿润显示面板410。光源模块420用于提供出射光线,电湿润显示面板410包括第一透明基板411、第二透明基板412以及像素单元,第一透明基板411和第二透明基板412相对设置。
其中像素单元包括第一电极(413A、413B、413C)、第一疏水层414、多个第一阻隔壁415、第二电极416、极性液体417以及多个第一非极性液体(418A、418B、418C)。第一电极413设置在第一透明基板411的像素区内;第一疏水层414设置在第一电极413上;多个第一阻隔壁415设置于第一疏水层414上,并设置在第一透明基板411的像素区的周边;第二电极416设置在第二透明基板412上;极性液体417设置在第二电极416和第一疏水层414之间;多个第一非极性液体418设置于第一疏水层414上,并设置在对应的第一阻隔壁415旁。

本优选实施例的电湿润显示装置在第一优选实施例的基础上,在第二电极416上设置有多个突出部4161,并且突出部4161远离相应的第一阻隔壁415进行设置。
本优选实施例的电湿润显示装置400使用时,由于第二电极416上突出部4161的设置,在第一电极(413A、413B、413C)上施加电压时,第一疏水层414上的第一非极性液体(418A、418B、418C)会更易聚集在第一阻隔壁415旁的第一疏水层414的第一凹陷区域419中,进一步避免了第一疏水层414上的第一非极性液体(418A、418B、418C)的滞留现象的产生。

本优选实施例的具体工作原理与上述的电湿润显示装置的第二优选实施例和第三优选实施例中的描述相同或相似,具体请参见上述电湿润显示装置的第二优选实施例和第三优选实施例中的相关描述。
