Description

蓝相液晶显示面板及蓝相液晶显示器 技术领域
本发明的实施例涉及一种蓝相液晶显示面板及蓝相液晶显示器。 背景技术
蓝相液晶具有如下突出的优点： （ 1 )具有亚毫秒的响应时间， 这不但使 液晶显示器有可能实现场序彩色显示模式， 还可以大大降低动态伪像， 而场 序彩色显示模式显示器的分辨率和光学效率是常规的 3倍； （ 2 )不需要定向 层（取向膜）， 可以大大筒化制管工艺过程； ( 3 )暗场时光学上是各向同性 的， 所以视角大， 并且非常对称； （4 )只要液晶盒的厚度大于一定值， 其透 明度对液晶盒的厚度不敏感， 所以特别适于制作大显示屏。
但蓝相液晶也有一些缺点， 主要是它的驱动电压太高。 目前， 通常的液 晶的驱动电压通常为 10V左右， 这远低于蓝相液晶的驱动电压（通常为 50V 及以上） ， 因此现有电路板所使用的材料和设计都无法达到蓝相液晶驱动电 压的要求。 发明内容

本发明的另一个方面提供了一种蓝相液晶显示器， 该蓝相液晶显示器包 括上述的蓝相液晶显示面板。
本发明的实施例基于彼此错位的上电极与下电极， 并结合设置于对盒基 板外部的上棱镜膜与下棱镜膜， 能够在保证高开口率的同时显著降低蓝相液 晶的驱动电压， 能够获得理想的视觉效果。 附图说明

为使本发明实施例的目的、 技术方案和优点更加清楚， 下面将结合本发 明实施例的附图，对本发明实施例的技术方案进行清楚、 完整地描述。显然， 所描述的实施例是本发明的一部分实施例， 而不是全部的实施例。 基于所描 述的本发明的实施例， 本领域普通技术人员在无需创造性劳动的前提下所获 得的所有其他实施例， 都属于本发明保护的范围。
除非另作定义， 此处使用的技术术语或者科学术语应当为本发明所属领 域内具有一般技能的人士所理解的通常意义。 "一个" 、 "一" 或 "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在 "包括" 或者 "包含" 前面的元件或者物件涵盖出 现在 "包括" 或者 "包含" 后面列举的元件或者物件及其等同， 并不排除其 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。
在本公开之中 "A和 /或 B" 这样的表述表示存在 A和 B中至少一个。 本发明实施例提供一种蓝相液晶显示面板， 包括相对设置的上基板、 下 基板以及上下基板之间的蓝相液晶， 上基板上朝向对盒方向设置有上电极， 下基板上朝向对盒方向设置有下电极； 所述上电极与下电极彼此错位。 所述 蓝相液晶显示面板还包括： 下棱镜膜， 所述下棱镜膜用于将要射入所述蓝相 液晶的光线折射， 使折射后的光线按照与蓝相液晶拉伸方向的形成预定穿透 角的方向透过蓝相液晶； 和 /或上棱镜膜， 所述上棱镜膜用于将与蓝相液晶拉 伸方向形成预定穿透角的方向透过蓝相液晶的光线折射， 使折射后的光线所 述上基板的方向射出。
蓝相液晶拉伸方向指的是蓝相液晶在上电极与下电极之间形成的电压差 作用下沿电场方向被拉伸的方向。 预定穿透角 Φ指光线穿透液晶层的方向与 液晶拉伸方向形成的夹角。 本发明的实施例中， 预定穿透角 Φ优选为 80° ~100° , 即折射后的光线按照垂直于或基本垂直于蓝相液晶 3拉伸方向的方 向透过蓝相液晶 3。 优选的， 折射后的光线按照垂直于蓝相液晶拉伸方向的 方向透过蓝相液晶， 即预定穿透角 Φ为 90。 。下面均以预定穿透角 Φ为 90。 为例进行介绍， 但是本发明并不限于此。
可以进行如图 1所示的设置。 图 1中的蓝相液晶显示面板包括相对设置 的两个基板： 上基板 1、 下基板 2, 上基板 1与下基板 2之间能够填充蓝相液 晶 3; 上基板 1上朝向对盒方向（朝向液晶层 3 )—侧设置有上电极 4, 下基 板 2上朝向对盒方向一侧设置有下电极 5, 即上电极 4隔着蓝相液晶 3与下 电极 5相对。 上基板 1上背向对盒方向 （背向液晶层 3 )一侧设置有上棱镜 膜 6,下基板 2上背向对盒方向一侧设置有下棱镜膜 7。下棱镜膜 7用于将要 射入所述下基板的光线折射后射入所述蓝相液晶， 使折射后的光线按照垂直 于蓝相液晶拉伸方向的方向透过蓝相液晶； 上棱镜膜 6用于将射出所述上基 板的光线折射， 使折射后的光线按照垂直于所述上基板的方向射出。
当然， 下棱镜膜 7也同样可以设置下基板 2在朝向下电极 5—侧上， 即 可以将下棱镜膜 7设置在下基板 2和下电极 5之间， 只要入射光线在进入蓝 相液晶之前经过下棱镜膜 7的折射即可， 在此不做限定； 同理， 上棱镜膜 6 也同样可以设置在上基板 1的朝向上电极 4一侧上， 即可以将上棱镜膜 6设 置在上基板 1和上电极 4之间， 只要光线穿透蓝相液晶之后经过上棱镜膜 6 的折射即可， 在此不做限定。
由图 1的实施例可见， 上电极 4与下电极 5不是完全正对位的， 而是彼 此错位的， 上电极 4和下电极 5部分重叠。 这样， 当上电极 4与下电极 5之 间形成电场时， 电场方向与基板 (上基板 1和 /或下基板 2 ) 的垂线之间形成 夹角 Θ , 而不是沿基板的垂线。 即， 上下电极彼此错位设置且部分重叠， 通 电之后可以形成倾斜电场。 因此， 上电极 4与下电极 5之间沿电场方向拉伸 的蓝相液晶 3的拉伸方向则同样与基板的垂线之间存在所述夹角 θ , 也即蓝 相液晶的拉伸倾斜角度。具体的蓝相液晶 3拉伸方向如图中双箭头线段所示。
由于蓝相液晶 3的拉伸方向与基板的垂线之间存在夹角 θ , 因此上电极 4与下电极 5之间的距离就可以设置得很近， 使得不需要过大的驱动电压就 可以驱动蓝相液晶 3。 该驱动电压是指驱动蓝相液晶分子发生拉伸或偏转的 电压， 即上电极和下电极之间形成的电压差。 通常， 上电极 4与下电极 5之 间的距离例如可以为 2μηι至 ΙΟμηι, 优选 2um~5um。 在该距离范围内， 驱动 蓝相液晶 3的电压通常在 10V至 15V之间， 甚至更低。 显然， 上述设置方式 能够显著降低蓝相液晶的驱动电压。 而且， 基于现有电路板所使用的材料和 设计， 本实施例就基本可以达到蓝相液晶驱动电压的要求。
可以理解的是， 所述上电极 4和下电极 5可以均为板状电极 (即电极为 平板状而无开口等），或者其一为狭缝状电极（即电极之间具有一定狭缝（开 口）或距离） ， 形成彼此部分重叠的电极结构， 只需满足所述上电极 4和下 电极 5相对液晶层彼此错位， 且使部分或全部蓝相液晶在上下电极之间实现 倾斜拉伸即可。
例如， 优选的， 所述上电极 4和下电极 5均为狭缝状电极， 这样可以使 电极与其相对液晶层设置的另一对应电极的相邻电极之间都形成倾斜电场， 可以有利于蓝相液晶拉伸倾斜后恢复原态。
为了保证高开口率， 可以尽量使射入基板（如下基板 2 ) 的光线垂直于 或基本垂直于蓝相液晶 3的拉伸方向。 在这种情况下， 由于射入下基板 2的 光线以及射出上基板 1的光线基本是垂直于相应基板的， 因此在下基板 2上 设置的下棱镜膜 7能够发挥作用， 将要射入下基板 2的垂直于或基本垂直于 下基板 2的光线折射， 使折射后的光线按照垂直于或基本垂直于蓝相液晶 3 拉伸方向的方向透过蓝相液晶 3 , 并射出上基板 1。 同样， 在上基板 1上设置 的上棱镜膜 6也能够发挥作用， 将射出上基板 1的垂直于或基本垂直于蓝相 液晶 3拉伸方向的光线折射， 使折射后的光线按照垂直于或基本垂直于上基 板 1的方向射出。 图中带剪头的虚线表明了光线的走向。
可以理解的是， 如果入射光线按照垂直于或基本垂直于蓝相液晶 3拉伸 方向的方向透过蓝相液晶时， 本发明实施例中可以不需要下棱镜膜 7; 同理， 如果特殊需要， 不需要经过蓝相液晶的光线按照垂直于或基本垂直于上基板 1的方向射出时， 本发明实施例中可以不需要上棱镜膜 6。
为了实现上棱镜膜和 /或下棱镜膜的对光线折射，方式之一是将上棱镜膜 和 /或下棱镜膜设置为倾斜表面，即棱镜膜的整体相对于基板呈现一个具有预 定倾斜角的表面。 棱镜膜的倾斜角， 为棱镜膜平行于基板的方向和棱镜膜倾 斜的方向形成的锐角。
例如， 优选的， 所述上棱镜膜与下棱镜膜关于蓝相液晶拉伸方向的垂直 方向轴对称， 这样可以尽可能保证入射光线经过下棱镜膜的折射后， 穿透蓝 相液晶并经过上棱镜膜折射后保持原有光线方向不变， 即入射光线经过上棱 镜膜与下棱镜膜折射后保持方向基本不变。
例如， 优选的， 上棱镜膜 6与下棱镜膜 7的倾斜表面相互平行， 即上下 棱镜膜具有相同的预定倾斜角。
为了实现上棱镜膜和 /或下棱镜膜的对光线折射，方式之二可以通过在上 棱镜膜和 /或下棱镜膜设置突起，所述下棱镜膜的突起用于将要射入所述下基 板的光线折射， 使折射后的光线按照垂直于蓝相液晶拉伸方向的方向透过蓝 相液晶； 所述上棱镜膜突起用于将射出所述上基板的光线折射， 使折射后的 光线按照垂直于所述上基板的方向射出。
如图 1和图 2所示，将上棱镜膜 6背向液晶层 3的表面设置有突起 8(例 如其截面呈直角三角形状） ， 即在有突起 8的上棱镜膜 6表面呈倾斜状， 使 上棱镜膜 6具有一定的倾斜度。 可以理解的是， 倾斜度（也为突起的倾斜角 或倾斜角度） 即为棱镜膜平行于基板 1的方向和棱镜膜倾斜的方向形成的锐 角。 例如， 突起 8的倾斜角 a, 即为该突起 8平行于基板 1的方向 8a (即长 边 L1 )和突起 8的倾斜的方向 8b (即斜边 R2 )形成的锐角 a。 倾斜角度可 以根据光线折射的需要而设定； 例如： a为 1度至 30度。
为了方便理解， 本发明实施例以突起为直角三角形状为例进行描述。 尤 其是以直角三角形突起的一条直角边平行于基板为例进行介绍。 此种结构的 突起， 有利于将入射光只经过直角三角形突起的斜边进行折射， 可以保证经 过直角三角形突起的斜边的光具有相同的折射角度和方向， 以及有利于将经 过蓝相液晶的出射光经过直角三角形突起的斜边的折射角度和方向相同。 同 理， 如图 3所示， 下棱镜膜 7的设置也可以类似于上棱镜膜 6, 在背向液晶 层的表面设置有突起 9。 上棱镜膜 6和下棱镜膜 7背向液晶层的表面的倾斜 度也可以根据光线折射的需要而设定。
如图 3所示， 上棱镜膜 6的突起 8和下棱镜膜的突起 9彼此错开， 即上 棱镜膜 6的突起 8和下棱镜膜突起 9部分重叠， 且均与上电极 4和下电极 5 部分重叠。
优选的， 上棱镜膜 6的突起 8和下棱镜膜的突起 9关于蓝相液晶拉伸方 向的垂直方向轴对称， 这样可以尽可能保证入射光线经过下棱镜膜突起的折 射后， 穿透蓝相液晶并经过上棱镜膜突起的折射后保持原有光线方向不变， 即入射光线经过两次折射后保持方向基本不变。
例如， 优选的， 同一棱镜膜设置多个有连续不间断的且倾斜角度相同的 突起， 有利于光线折射后方向的一致性。 例如， 上棱镜膜 6设置多个突起 8, 下棱镜膜的设置多个突起 9。
例如， 优选的， 上棱镜膜 6的突起 8和下棱镜膜的突起 9的倾斜方向相 反。 例如， 上棱镜膜 6的突起 8倾斜的方向 8b向左， 下棱镜膜 7的突起 9 倾斜的方向 9b向右，有利于控制光线的折射角度和光线的入射方向和出射方 向。
例如， 优选的， 上棱镜膜 6和 /或下棱镜膜 7的倾斜角度与蓝相液晶的拉 伸倾斜角度 Θ互余或相同，有利于光线经过上棱镜膜 6、液晶层与下棱镜膜 7 后保持一致。
相邻的上电极 4之间的距离 Ml (或者称狭缝）可以大于上电极 4与下 电极 5之间的距离 HI; 当然， 在保证降低蓝相液晶 3驱动电压的情况下，相 邻的上电极 4之间的距离 Ml也可以等于甚至小于上电极 4与下电极 5之间 的距离 Hl。 同理，相邻的下电极 5之间的距离 M2可以大于上电极 4与下电 极 5之间的距离 HI； 当然， 在保证降低蓝相液晶 3驱动电压的情况下，相邻 的下电极 5之间的距离 M2也可以等于甚至小于上电极 4与下电极 5之间的 距离 Η1。
无论是上电极 4还是下电极 5, —个电极通常对应一个子像素。 如图 3 所示， 虚线框内为一个子像素。 每个子像素中， 一个上电极 4对应一个下电 极 5,并且同时对应一个上棱镜膜突起 8和一个下棱镜膜突起 9,这样有利于 各个子像素区域的形成的倾斜电场均匀性。
例如， 优选的， 电极相对另一电极的错开方向和与该电极相对液晶层设 置的棱镜膜的突起的倾斜角开口方向一致。 例如， 下电极 5与上电极 4的错 开方向 （即下电极的左端往对应的上电极的左端的方向， 或下电极的右端往 对应的上电极的右端的方向）为 F1 , 下电极相对液晶层设置的上棱镜膜的突 起 8的倾斜角 a开口方向相同， 均向左。
例如， 优选的， 各个子像素中对应的所述狭缝状电极的上电极 4和下电 极 5彼此错开的距离 S2相同 （即下电极的左端与对应的上电极的左端的距 离， 或下电极的右端与对应的上电极的右端的距离） ， 这样可以使蓝相液晶 在拉伸倾斜的角度趋近一致。
同理， 各个子像素中对应的上下棱镜膜的突起彼此错开的距离 S1 也相 同， 该距离 S1 即下棱镜膜突起的右端与对应的上棱镜膜的突起的左端的距 离。
例如， 优选的， 电极相对另一电极的错开距离 S1 小于或等于该电极与 相对液晶层设置的棱镜膜突起的错开距离 Q1 ,该距离 Q1即下电极的左端与 上棱镜膜突起的左端的距离， 或下电极的右端与对应的上棱镜膜突起的右端 的距离。 例如， 下电极 5与上电极 4的错开距离 S2, 下电极 5与相对液晶层 设置的上棱镜膜突起 8错开距离 Ql , S2 < Q1 , 有利于光线穿过液晶层后光 程和角度的控制。 可以理解的是， 电极之间的错开距离以及相互匹配的棱镜 膜错开距离， 有利于减少光线穿透棱镜膜和液晶层的光程， 提高光线的利用 率.
例如， 优选的， 棱镜膜的突起可以覆盖位于液晶层同侧的相邻电极的缝 隙或间隙， 可以尽量保证光线穿透液晶层后全部发生折射。
例如， 优选的， 棱镜膜的突起可以覆盖所对应的子像素区域， 可以尽量 保证所有穿透子像素区域的光线均被利用。
再有， 无论是上电极 4还是下电极 5, —个电极通常对应一个子像素。 但在实际应用中，也可以对上电极 4和 /或下电极 5中的一个或多个电极进行 如图 2所示的设置， 使得两个、 三个甚至多个上电极 4和 /或下电极 5对应一 个子像素。 图 4中， 虚线框内的两个上电极 4对应一个子像素， 虚线框内的 两个下电极 5对应一个子像素。
另夕卜， 上电极 4中可以包括正电极和 /或负电极； 同理， 下电极 5中也可 以包括正电极和 /或负电极。 例如： 上电极可以均为正电极， 下电极均为负电 极； 或者， 上电极的正负电极交错设置， 下电极的也是正负交错设置。
当然， 提供给上下电极的电压的大小和极性均可以两者同时发生变化或 两者之一发生变化。只要满足蓝相液晶在上下电极的电压差作用下发生偏转， 使显示器件正常工作即可， 在此不做限定。
上棱镜膜 6和下棱镜膜 7的材料优选具备一定折射率、 高透过率、 易加 工性和热变形稳定性等特点，符合上述要求的聚合物树脂都可以采用， 比如： 聚对苯二曱酸乙二醇酯（PET ) 、 聚碳酸酯（PC ) 、 聚醚醚酮 （PEEK ) 、 聚苯乙烯（PS )、高密度聚乙烯（HDPE )、低密度聚乙烯、无规聚丙烯（PP )、 聚乙烯四氟乙烯（ETFE )等。 例如， 上棱镜膜 6和下棱镜膜 7采用相同的材 料。
需要说明的是， 上基板 1和下基板是相对而言， 上电极 4和下电极也是 相对而言。 例如； 光线也可以从上基板射入并从下基板射出。 本发明实施例 中， 上基板 1可以是阵列基板或对置基板（例如彩膜基板） ， 下基板 2则可 以是对应的对置基板或阵列基板； 上电极 4可以是与上基板 1对应的像素电 极或公共电极， 下电极 5则可以是与下基板 5对应的公共电极或像素电极。 例如： 下基板 2为阵列基板， 下电极为像素电极， 上基板为对置基板， 上电 极为公共电极。 当对置基板为彩膜基板时， 其上形成有例如红绿蓝色的子像 素。
相邻的上电极 4之间可以设置绝缘层， 相邻的下电极 5之间也可以设置 绝缘层， 所述绝缘层用于使相邻的电极之间绝缘。
可以理解的是， 本发明实施例中的涉及到的参数的具体数值都可以根据 需要而设定。 例如： 以各子像素为例， 当入射光线的入射角为 σ , 下棱镜膜 的折射率为 nl , 下棱镜膜倾斜角为 a, 入射光线经过下棱镜膜的折射后的折 射角为 η, 上电极和下电极之间错开的距离为 S2, 上下电极之间的距离为 HI , 蓝相液晶的拉伸倾斜角为 Θ, 预定穿透角为 Φ, 则 σ=α, nl=sina/sinii, tge=s2/m, (D=i80°-e- =90°。 同理， 上棱镜膜的折射原理也与下棱镜膜相同， 在此不再赘述。
结合以上描述可见， 本发明基于彼此错位的上电极与下电极， 并结合设 置于对盒基板外部的上棱镜膜与下棱镜膜， 能够在保证高开口率的同时显著 降低蓝相液晶的驱动电压， 能够获得理想的视觉效果。
以上所述仅是本发明的示范性实施方式， 而非用于限制本发明的保护范 围， 本发明的保护范围由所附的权利要求确定。
