Description
技术领域
本发明涉及一种显示装置,包括具有基本平面表面的基本透明的基片。
背景技术
这种类型的显示装置在例如“New Reflective Display Based onTotal Reflection in Prismatic Microstructures”(Proc.20th IDRCconference,pp.311-314(2000))一文中有描述。该文说明了基于受控抑制的全内反射的原理。通过用电泳将光吸收颗粒移向棱柱形表面,使得全内反射在一种状态下不可能发生。
电泳显示装置基于带电并且通常是有色颗粒在电场影响下在具有不同透射率或反射率的两种极限状态之间的运动。使用这些装置,可以将暗(有色)字母成象在亮(有色)背景上,以及反过来将亮字母成象在暗背景上。
电泳显示装置因此取代纸张的功能被大量用在显示装置中,称作“白纸”应用(电子新闻纸、电子日记本)。
发明内容
本发明基于一个完全不同的机理,用于实现反射光在两种(暗和亮)光学状态下的差异。
为此目的,根据本发明的显示装置包括具有平面表面的透明的基片,所述显示装置包括一个位于象素位置的储存器,该储存器含有至少两种具有不同折射率或不同吸收系数以及不同电导率的不相混流体,所述显示装置还包括用于使所述流体互相相对位移的驱动装置,其特征在于,所述基片具有面向所述平面表面的棱柱形表面。
后面将会解释,光束在所述两种状态之一下完全反射(通过对所述流体的适当选择从而选择折射率),同时光束在另一种状态下由所述流体吸收(或者部分透射并在其他地方吸收)。
面向观看一侧观看者的基片表面可以是平面,同时该基片的至少一部分棱柱形表面构成储存器的部分围壁。或者,它也可以是棱柱面,同时该基片的至少一部分平面表面构成储存器的部分围壁。
为了使所述流体互相相对位移,利用电导率的差别,并且在象素储存器的围壁区域,驱动装置包括至少两个能够与所述流体电耦合的电极。
在象素储存器的围壁区域,驱动装置优选包括两个与流体绝缘的电极,和一个与所述导电流体电接触的第三电极。
为此目的,一种矩阵装置包括多个象素,位于行电极(或选择电极)与列电极(或数据电极)的交点区域,在象素电极与行电极或列电极之间具有至少一个开关元件。
在参照下面所述的实施例之后将会明白本发明的这些和其他方面。
在附图中:
附图说明
图1简要表示本发明显示装置所基于的原理,
图2表示图1的变体,
图3表示本发明显示单元的一种可能形式,而
图4表示本发明显示单元的另一可能形式,以及
图5为本发明显示装置的电路等同示意图。
具体实施方式
这些附图只是示意性的,没有按比例画出;对应的部件都用相同的标号加以表示。
图1简要表示一种具有两种液体或者流体3、4处位于透明的例如玻璃或合成材料外壳2中的显示单元1,所述流体不会互相混合,并且其中之一导电而另一种绝缘。在此例中,显示单元1包括例如含水(有色)溶液4(导电),例如亚甲蓝或普鲁士蓝(C6Fe2Kn6)的水溶液,并且选择气体比如氮气或非极性油(比如烷烃(例如十二烷或十六烷)、硅油、氯萘、溴萘或1-溴代十二烷)作为绝缘流体。
在流体的两侧,显示单元1包括绝缘电极5、6,其通常馈送以对于多个象素共用的电压Vcom1、Vcom1,在相关例子中馈送电压为0和V。显示单元1还包括电极7,通过外壳2与导电流体4电接触。电极7被馈送以电压Vpixel,由它调整显示单元的光学状态。尽管为理解本发明起见将电极5、6画在外壳的外部,但是它们实际上设置在外壳内部,并通过具有较低润湿滞后的绝缘涂层比如含氟聚合物与所述流体绝缘。
由于电润湿现象或电毛细现象,导电流体4由静电力沿电极5、6的方向吸引,也即由正比于(Vpixel-Vcom1)2的力向电极5吸引以及由正比于(Vpixel-Vcom2)2的力向电极6吸引。各静电力之差限定了流体4在显示单元中的位置。在图1中,Vcom1=0并且Vcom2=V。在Vpixel=0时,导电流体4处于电极6的位置(图1a),而在Vpixel=V时,导电流体4处于电极5的位置(图1b)。通过改变象素电压Vpixel,可以由此影响导电流体4的位置。尽管电极7在此例中被示为导电电极,并且突入所述流体中,但是这不是必需的。也可以通过电容耦合在导电流体上提供电压。在此情况下,电极7设置在例如储存器2的外部或者设有绝缘保护涂层。
图2表示图1的变体,其中同样馈送以电压Vpixel的电极7被分成两个子电极7、7′。流体之间的界面现在基本平行于外壳2的上下壁,并且由于所用效果而导致在图示平面内有较小偏移(在图2中,这通过斜线8示意画出)。
图3表示上述原理如何用于基于全内反射的显示装置中。显示单元1包括玻璃或合成材料制成的透明基片10,具有基本平面的表面11和与所述平面表面相对的基本棱柱形的表面12、12′。该显示单元包括一个储存器13,它含有具有不同折射率的至少两种不相混流体3、4,所述流体不会互相混合并且其一为导电流体而另一为绝缘流体。显示单元1还包括馈送以电压Vpixel的电极7,该电极通过外壳(未画出)与导电流体4电接触。尽管这在图3中没有画出,但显示单元最好具有用于所述两种流体的与温度变化等所致膨胀有关的公共溢流储存器(或者可用于多个显示单元)。显示单元在所述流体的两侧具有绝缘电极5、6,所述电极被馈送以公共电压Vcom1、Vcom1,在相关例子中馈送电压为0和V。
在Vpixel=0时,导电流体4处于电极6的位置(图3a),而在Vpixel=V时,导电流体4处于电极5的位置(图3b,其中电极未画出)。在第一所述情况(图3a)下,入射光束14由透明(ITO)电极5透过并通过适当选择绝缘流体的折射率而受到全反射。反射光束14′再一次受到表面12′的全反射,二次反射光束14″基本上没有任何光损耗地离开显示单元1。在第二种情况下(图3b),入射光束14同样由透明(ITO)电极5透过,但继而在表面12上由含水溶液4全部或部分吸收。光束14的可能反射部分14′在表面12′上被吸收。
在此例中,电极6仅表示在象素的下侧上,因为当例如在矩阵显示装置中将数个象素组合在一个基片上时,这是有利的。在其他情况下,电极6最好也沿着储存器13的围壁设置。这在图3a中用虚线示意表示出。
图4简要表示如图2所述两个类似象素和储存器的组合,但现在在象素一侧上具有基本平面的表面11,而在观看一侧上具有基本棱柱形的表面12、12′。除此之外,相同的标号具有与前述附图中相同的含义。
图5表示可应用本发明的彩色显示装置1的一部分的等效电路。它包括象素20的矩阵,其中象素20位于行电极(或选择电极)27与列电极(或数据电极)26的交点区域。行电极1至m由行驱动器24依次选择,而列电极1至n由数据寄存器25提供数据。列1、4、7、…、n-2中的象素在此例中构成红色象素,列2、5、8、…、n-1中的象素在此例中构成蓝色象素,列3、6、9、…、n中的象素在此例中构成绿色象素。为此目的,如果需要,输入数据22在处理器23中首先处理。行驱动器24与数据寄存器25之间相互同步由驱动线28进行。
来自行驱动器24和数据寄存器25的驱动信号通过薄膜晶体管(TFT)29选择象素20,其中薄膜晶体管29的栅极电连接至行电极27,其源极电连接至列电极26(属有源驱动)。列电极26处的信号经由TFT传送至与其漏极相连的象素20的电极7。电极7具有与上面参照图1至4所述的相同功能。象素20的其他电极5、6连接至例如具有Vcom1(在此例中为接地)和Vcom2(在此例中为V)的一个(或多个)公共电极。在图5所示的例子中,仅对于一个象素20简要画出了这种TFT29。
在本发明的范围内当然可以有多种变型。例如,可以采用具有不同折射率的两种不相混流体。在一定的电极结构中,入射光可以到达象素的下侧。如果需要,象素可以在其下侧上设有光吸收层。
替代薄膜晶体管(TFT)29,可以选择其他开关元件例如二极管电路。
第三电极5也可以省略,假定所用流体3、4具有产生所述位移的疏水性差异(围壁具有浸润特性的差异)。从而所述两个电极之一用作驱动电极。
如上所述,也可以采用电容耦合;这同样适用于通过TFT或其他开关元件对电极的驱动。
本发明的保护范围并不限于上述实施例。
本发明存在于每个及所有新颖特征和特定特征的每个及所有组合之中。权利要求书中的标号不限制其保护范围。动词“包括”及其变形的使用并不排除权利要求中存在所述元件之外的元件。元件之前使用量词“一个”或“一”并不排除存在多个这种元件。
