本公开的第一实施例提供一种用于OLED显示单元的防炫目装置,所述防炫目装置设置在用于实现镜面显示的所述OLED显示单元的上方以限制特定波长的光反射,使得所述OLED显示单元用在例如车辆后视镜上时,用户观看所述OLED显示单元显示的图像时能够实现防炫目的效果,提升后视镜的整体显示效果。需要说明的是,这里的所述OLED显示单元可以采用现有的OLED结构,其包括低温多晶硅(LTPS)背板、PDL发光层、薄膜封装(TFE)层以及反射金属层。本实施例涉及的所述防炫目装置如图1所示,其包括顶电极1和底电极2,所述底电极2设置在所述OLED显示单元100上,例如可以贴合设置在所述OLED显示单元100的上方,所述顶电极1设置在所述底电极2的上方,所述顶电极1和所述底电极2用于接收外部施加的电压;在所述顶电极1和所述底电极2之间设置电致变色层3,所述电致变色层3用于限制特定波长的光在所述OLED显示单元上方发生反射。
进一步地,继续如图1所示,所述电致变色层3包括阳离子电致变色层31和阴离子电致变色层32,所述阳离子电致变色层31贴合所述顶电极1的下表面设置,所述阴离子电致变色层32贴合所述底电极2的上表面设置,在所述阳离子电致变色层31和所述阴离子电致变色层32之间设置聚合物电介质凝胶层33以形成三层结构。
具体地,所述阳离子电致变色层31采用三苯胺、二茂铁、吩嗪、吩噻嗪中的至少一种制成,所述阴离子电致变色层32采用紫精或者紫精的取代衍射物中的至少一种制成,紫精是一类具有通式(C5H5NR)2n+的有机化合物,这里的紫精的取代衍射物例如可以是乙基紫精;所述聚合物电解质凝胶层33作为氧化还原填存层,以增强导电性。
进一步地,为了不影响所述OLED显示单元的显示效果,所述顶电极1和/或所述底电极2采用透明导电材料制成,所述透明导电材料为氧化铟锡和/或铟锌氧化物。
本公开的第二实施例提供一种用于OLED显示单元的防炫目装置的制备方法,这里的防炫目装置为第一实施例中的防炫目装置,其设置在用于实现镜面显示的所述OLED显示单元的上方以限制特定波长的光反射,使得所述OLED显示单元用在例如车辆后视镜上时,用户观看所述OLED显示单元显示的图像时能够实现防炫目的效果,提升了显示效果。需要说明的是,这里的所述OLED显示单元可以运用在车辆的后视镜上,对于所述OLED显示单元的制备,可以首先按照常规工艺制备低温多晶硅(LTPS)背板、发光层、薄膜封装(TFE)层以及镜面反射金属层,从而制作实现镜面显示的所述OLED显示单元。在制备所述OLED显示单元后,通过本公开实施例涉及的制备方法制备防炫目装置,并最终将所述防炫目装置设置在所述OLED显示单元的上方,其中,所述防炫目装置的制备方法包括以下步骤:
S101,采用溅射镀膜(Sputter)工艺制备顶电极1和底电极2;其中,为了不影响所述OLED显示单元的显示效果,所述顶电极1和/或所述底电极2采用透明导电材料制成,所述透明导电材料为氧化铟锡和/或铟锌氧化物;所述顶电极1和所述底电极2的厚度在100nm-200nm范围内;
S102,在所述底电极2上采用涂胶工艺依次制备阴离子电致变色层32、聚合物电解质凝胶层33和阳离子电致变色层31,也就是,在所述底电极2上形成所述电致变色层3的三层结构;其中,所述阳离子电致变色层31采用三苯胺、二茂铁、吩嗪、吩噻嗪中的至少一种制成,所述阴离子电致变色层32采用紫精或者紫精的取代衍射物中的至少一种制成,这里的紫精的取代衍射物例如可以是乙基紫精;所述聚合物电解质凝胶层33作为氧化还原填存层以增强导电性。
S103,将所述顶电极1设置在所述阳离子电致变色层31上。
在制作例如用于车辆后视镜上的防炫目的所述OLED显示装置时,可以将在上述方法制备的所述防炫目装置反贴在所述OLED显示单元上,以获得具有防炫目作用的实现镜面显示的OLED显示装置。
采用所述第一实施例和所述第二实施例的所述防炫目装置从而能够实现防炫目效果,具体地,在例如通过车载电源向所述顶电极1和所述底电极2的两侧施加电压时,在电压的驱动下所述电致变色层3内部的电子在阳离子电致变色层31、所述聚合物电解质凝胶层33和阴离子电致变色层32之间发生移动,从而形成氧化还原的稳定循环,以能够吸收一定特定波长范围的光。
具体地,所述电致变色层3的内部在持续电压的施加下,由所述阳离子电致变色层31和所述阴离子电致变色层32作用形成具有颜色的例如乙基紫精的自由基阳离子,从而使得所述电致变色层3对波长在500-700nm范围内的黄色光进行吸收,如图2所示,图2示出了乙基紫精在驱动电压(0-0.7V)范围内的可见光吸收光谱。考虑到不同颜色的光的波长不同,人的眼睛对蓝色光的感度较差,蓝光是人类肉眼最能适应的光源,这样使得所述电致变色层3吸收较多蓝色光从而使得所述OLED显示单元在显示的视觉上呈现蓝色,因此,通过所述电致变色层3实现限制具有特定波长的光例如黄色光的反射,避免被用户的眼睛看到,从而实现防止炫目的效果;当向所述顶电极1和所述底电极2断开施加的电压时,例如乙基紫精的分子将回归稳定的二价态,并进一步实现着色-褪色过程,使得所述电致变色层3恢复无色状态,从而不影响镜面反射和所述OLED显示单元的显示效果。
本公开实施例的防炫目装置可以使实现镜面显示的OLED显示单元在应用于车载后视镜时改善因强光导致产生炫目的问题,提升使用体验,避免交通事故的发生。
本公开的第三实施例提供一种用于OLED显示单元的防炫目装置,所述防炫目装置设置在用于实现镜面显示的所述OLED显示单元的上方以限制特定波长的光反射,使得所述OLED显示单元用在例如车辆后视镜上时,用户观看所述OLED显示单元显示的图像时能够实现防炫目的效果,提升了显示效果。需要说明的是,这里的所述OLED显示单元可以采用现有的OLED结构,其包括低温多晶硅(LTPS)背板、PDL发光层、薄膜封装(TFE)层以及反射金属层。本实施例涉及的所述防炫目装置如图3所示,其包括顶电极1和底电极2,所述底电极2设置在所述OLED显示单元100上,例如可以贴合设置在所述OLED显示单元100的上方,所述顶电极1设置在所述底电极2的上方,所述顶电极1和所述底电极2用于接收外部施加的电压;在所述顶电极1和所述底电极2之间设置电泳偏振层4,所述电泳偏振层4用于限制特定波长的光在所述OLED显示单元上方发生反射。
具体地,所述电泳偏振层4采用向列液晶材料(nematic liquid crystal)制成,这里的向列液晶材料是一种透明的液体,它能使通过液体的光波发生偏振,以改变这些光波的路径;也就是,当所述电泳偏振层4受到电压变化的影响后,只允许一定波长范围的光线通过从而使得入射光发生偏振这种偏振的范围取决于外加电场的强度或者电压大小,同时限制一定波长的光线发生反射,例如波长在500-700nm范围内的黄色光。
进一步地,为了不影响所述OLED显示单元的显示效果,所述顶电极1和/或所述底电极2采用透明导电材料制成,所述透明导电材料为氧化铟锡和/或铟锌氧化物。
本公开的第四实施例提供一种用于OLED显示单元的防炫目装置的制备方法,这里的防炫目装置为第三实施例中的防炫目装置,其设置在用于实现镜面显示的所述OLED显示单元的上方以限制特定波长的光反射,使得所述OLED显示单元用在例如车辆后视镜上时,用户观看所述OLED显示单元显示的图像时能够实现防炫目的效果,提升了显示效果。需要说明的是,这里的所述OLED显示单元可以运用在车辆的后视镜上,对于所述OLED显示单元的制备,可以首先按照常规工艺制备低温多晶硅(LTPS)背板、发光层、薄膜封装(TFE)层以及镜面反射金属层,从而制作实现镜面显示的所述OLED显示单元。在制备所述OLED显示单元后,通过本公开实施例涉及的制备方法制备防炫目装置,并最终将所述防炫目装置设置在所述OLED显示单元的上方,其中,所述制备方法包括以下步骤:
S101,采用溅射镀膜(Sputter)工艺制备顶电极1和底电极2;其中,为了不影响所述OLED显示单元的显示效果,所述顶电极1和/或所述底电极2采用透明导电材料制成,所述透明导电材料为氧化铟锡和/或铟锌氧化物;所述顶电极1和所述底电极2的厚度在100nm-200nm范围内;
S102,在所述底电极2上使用例如向列液晶材料(nematic liquid crystal)通过面板成型(Cell)工艺制备所述电泳偏振层4,这里的向列液晶材料是一种透明的液体,它能使通过液体的光波发生偏振,以改变这些光波的路径;也就是,当所述电泳偏振层4受到电压变化的影响后,只允许一定波长范围的光线通过从而使得入射光发生偏振,这种偏振的范围取决于外加电场的强度或者电压大小。
S103,将所述顶电极1设置在所述电泳偏振层4上。
在制作例如用于车辆后视镜上的防炫目的所述OLED显示装置时,可以将在上述方法制备的所述防炫目装置反贴在所述OLED显示单元上,以获得具有防炫目作用的实现镜面显示的OLED显示装置。
采用所述第三实施例和所述第四实施例的所述防炫目装置从而能够实现防炫目效果,具体地,在例如通过车载电源向所述顶电极1和所述底电极2的两侧施加电压时,当两侧对应电极上施加的电压超过液晶的阈值电压时,液晶中离子团(来自添加剂)的推动足以扰乱液晶分子的排列,使液晶的折射率发生了变化并进一步形成散射中心,从而使入射光中特定波长的光发生强烈散射,这样,透明的电极部位就显示出乳白色(类似磨砂玻璃),从而达到了防炫目的目的;当向所述顶电极1和所述底电极2的两侧施加的电压取消后,液晶分子即恢复原来的排列重新变为透明,从而不影响镜面反射和所述OLED显示单元的显示效果。
本公开实施例的防炫目装置可以使实现镜面显示的OLED显示单元在应用于车载后视镜时改善因强光导致产生炫目的问题,提升使用体验,避免交通事故的发生。
本公开的第五实施例提供一种OLED显示装置,所述OLED显示装置包括OLED显示单元和上述第一和第三实施例中的所述防炫目装置,所述防炫目装置设置在用于实现镜面显示的所述OLED显示单元的上方以限制特定波长的光反射,使得所述OLED显示装置用在例如车辆后视镜上时,用户观看所述OLED显示装置显示的图像时能够实现防炫目的效果,提升后视镜的整体显示效果。需要说明的是,这里的所述OLED显示单元可以采用现有的OLED结构,其包括低温多晶硅(LTPS)背板、PDL发光层、薄膜封装(TFE)层以及反射金属层。
