第一电极111接收第一电压,第二电极114接收第二电压。当第一电压和第二电压不同,从而形成电压差时,第一电极111与第二电极114之间产生电场,电致伸缩层113在该电场的作用下会发生形变(例如弯曲),对入射至电致伸缩层113上光线的传播方向进行调节。

电致伸缩层的材料可以包括:AOC、DEAP、ESGE、ESP、EVEM、FEP、LCE、CNT、CP、ERF、IPG和IPMC等电活性聚合物中至少之一。
可以采用各种手段来实现第一电压和第二电压之间的电压差的控制。
例如,在一些实施例中,显示面板包括驱动电路,驱动电路连接第一电极和第二电极来给第一电极和第二电极分别施加第一电压和第二电压。在一些实施例中,显示面板还可以包括与驱动电路连接的控制器或控制电路,该控制器或控制电路可以控制经由驱动电路施加到第一电极和第二电极的第一电压和第二电压的大小(换言之,控制第一电压和第二电压之间的电压差)。
例如,在第一显示阶段,参照图1,控制器可以使得在施加于第一电极的第一电压和施加于第二电极的第二电压之间形成第一电压差,以在第一电极与第二电极之间产生第一电场,以使第一电极与第二电极之间的电致伸缩层在该电场作用下形变为凸透镜结构(例如如图1所示),改变显示器件光线的传播方向,使散射光线变成平行光线或内聚光线,减小视角,从而达到防窥的效果;或者,控制器还可以使得施加于第一电极的第一电压以及施加于第二电极的第二电压之间形成第二电压差,来在第一电极与第二电极之间产生第二电场,使第一电极与第二电极之间的电致伸缩层形变为凹透镜结构,使平行光线或内聚光线变成扩散光线,达到增大视角的效果。
在第二显示阶段,参照图2,控制器可以使施加于第一电极的第一电压与施加于第二电极的第二电压相同,从而在第一电极与第二电极之间不产生电场,以使第一电极与第二电极之间的电致伸缩层恢复成平面结构,该平面结构与显示基板平行(例如如图2所示)。
本实施例提供的显示面板,将调节装置设置在显示基板的出光侧,调节装置中的电致伸缩层在电场的作用下发生形变形成透镜结构,从而改变入射光线的传播方向,改变显示视觉角度大小,使显示面板达到防窥(减小视角)或共享(增大视角)的效果。
在本公开实施例中,第一显示阶段和第二显示阶段并不意味着这两个显示阶段的先后顺序,而仅仅是为了表示显示面板处于两种不同的状态。第一显示阶段和第二显示阶段可以由用户定义。例如,当用户启动防窥视模式或分享模式时,显示装置可以处于第一显示阶段;当用户在正常模式下使用显示装置时,显示装置可以处于第二显示阶段。
在一些实施例中,第一电极111靠近显示基板10设置,第一电极111的材料例如可以为ITO(Indium Tin Oxide,铟锡氧化物)或其他透明电极。
第一绝缘层112的材料为透明绝缘材料,例如可以为氮化硅或者OC材料等。
第二电极114的材料例如可以为ITO或者纳米银线等柔性电极材料。
在实际应用中,显示基板10包括多个像素单元,为了对每个像素单元的光线传播方 向进行精确调节,可以设置第一电极111包括多个条状子电极,各条状子电极与各像素单元一一对应。这样,在第一显示阶段,电致伸缩层在电场的作用下可以形成多个透镜结构,各透镜结构与条状子电极(或像素单元)一一对应。
在一些实施例中,参照图3,显示基板10包括:衬底31,层叠设置在衬底31上的多个薄膜晶体管、第二绝缘层33、第三电极34,以及图案化形成在第三电极34和第二绝缘层33上的有机发光层35和黑色矩阵36,第三电极34与各薄膜晶体管通过设置在第二绝缘层33上的过孔331连接,第一电极111设置在有机发光层35和黑色矩阵36背离衬底31的一侧,第三电极34为阳极或阴极,第一电极111复用为与第三电极34对应的阴极或阳极。
其中,薄膜晶体管可以包括依次形成在衬底31上的栅极321、栅极绝缘层322、有源层323以及源漏电极324。
在实际应用中,显示基板10的一种形成过程如下:
通过成膜、涂布PR胶、曝光、显影、刻蚀等一系列构图工艺在衬底31上制作栅极321;在栅极321表面覆盖栅极绝缘层322;在栅极绝缘层322上制作Active层即有源层323;在有源层323上制作源漏电极324;在源漏电极324上覆盖第二绝缘层33;在第二绝缘层33上形成过孔331,连接OLED第三电极34;然后图案化形成有机发光层35和黑色矩阵36,黑色矩阵36用于分割定义像素单元;然后形成OLED中与第三电极34相对应的另一电极,这一电极可以与调节装置11中第一电极111共用。当第三电极34为OLED阳极时,第一电极111复用为OLED的阴极;当第三电极34为OLED阴极时,第一电极111复用为OLED的阳极。

需要说明的是,本实施例中的显示装置可以为:电子纸、手机、平板电脑、电视机、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
在本公开的实施例中,控制器可以是数字控制器或模拟控制器。控制器也可以是显示装置内的处理器。
图4A示出根据本申请实施例提供的一种显示面板的控制方法,该控制方法可以应用 于上述任一实施例所述的显示面板,该控制方法可以包括:
4001:控制施加于第一电极的第一电压和施加于第二电极的第二电压之间的电压差,来控制在所述第一电极与所述第二电极之间产生的电场,从而控制所述电致伸缩层在所述电场的作用下的形变,以对入射至所述电致伸缩层的光线的传播方向进行调节。
在实际应用中,该步骤可以由上述控制器或控制电路执行。
图4B示出根据本申请另一实施例提供的一种显示面板的控制方法。在该显示面板中,第一电极靠近显示基板设置,第二电极为柔性电极,且第一电极包括多个条状子电极。

步骤401:在第一显示阶段,通过使施加于所述第一电极的第一电压与施加于所述第二电极的第二电压之间形成电压差,来在所述第一电极与所述第二电极之间产生电场,该电场使所述第一电极与所述第二电极之间的电致伸缩层形成多个透镜结构,各所述透镜结构与所述条状子电极一一对应。
这例如包括:使施加于所述第一电极的第一电压与施加于所述第二电极的第二电压之间形成第一电压差,从而在第一电极与第二电极之间产生第一电场,第一电场使所述电致伸缩层发生形变,成为凹透镜结构,以使得入射至所述电致伸缩层的光线在出射时发散,例如使平行光线或内聚光线变成扩散光线,达到增大视角的效果。或者,使施加于所述第一电极的第一电压与施加于所述第二电极的第二电压之间形成第二电压差,从而在第一电极与第二电极之间产生第二电场,第二电场使所述电致伸缩层发生形变,成为凸透镜结构,以使得入射至所述电致伸缩层的光线在出射时汇聚,例如使散射光线变成平行光线或内聚光线,减小视角,从而达到防窥的效果。第一电压差与第二电压差反相。
本领域技术人员可以想到,通过调节电压差的大小可以使电致伸缩层产生不同程度的形变。通过调节电压差的极性,可以使电致伸缩层产生不同方向的形变。本领域技术人员可以根据本公开的教导进行各种修改。
步骤402:在第二显示阶段,使施加于所述第一电极的第一电压与施加于所述第二电极的第二电压相同,以使所述第一电极与所述第二电极之间的电致伸缩层形成平面结构,所述平面结构与所述显示基板平行。
本领域技术人员可以理解,第一显示阶段和第二显示阶段并不一定是必须按照图中的顺序执行,图4A和图4B中仅仅是示例性方法的流程图。其步骤的顺序可以改变,并且根据本公开的方法可以包括更多或更少的步骤。
