显示面板200可以实现显示功能,以显示画面。
偏光组件400可以实现偏光作用,偏光组件400可以作为显示面板200的偏光结构。诸如偏光组件400可以作为显示面板200的线性偏光片、光栅等,偏光 组件400可以偏转显示面板200发出的光线,偏光组件400还可以起到遮挡显示面板200的器件。
请参阅图3和图4,图3为图2所示显示装置中偏光组件的结构示意图,图4为图3所示偏光组件的拆分图。偏光组件400可包括第一基层440、第一导电层480、电致变色层420、第二导电层410和第二基层460。
第一基层440可以作为偏光组件400的基体结构。第一基层440可以采用透明材料,诸如无色透明玻璃。第一基层440可以开设多个槽结构,可以称为间隔槽442或者说沟道,间隔槽442可以从第一基层440的一面开设形成,各个间隔槽442可以等间隔设置,且相互平行。诸如各个间隔槽442均为条形的槽结构。各个间隔槽442的宽度可以相同,各个间隔槽442的长度也可以相同,各个间隔槽442的深度也可以相同。
第一基层440上设置有多个间隔条424,诸如第一基层440开设多个间隔槽442可以在第一基层440上形成多个间隔条424,间隔条424的个数可以多于间隔槽442的个数。诸如间隔条424的条数比间隔槽442的条数多一条。相邻两个间隔条424之间具有一个间隔槽442。由于第一基层440采用透明材料,诸如无色透明玻璃,从而间隔条424也可以为无色透明玻璃。各个间隔条424的宽度可以相同,各个间隔条424的长度也可以相同,各个间隔条的高度也可以相同。
需要说明的是,间隔条424并不一定直接在第一基层440上开设间隔槽440形成,也可以是在一个板状结构的第一基层上设置多个透明玻璃条形成,多个透明玻璃条可以采用透明胶粘贴在第一基层上,从而相邻两个透明玻璃条之间可以形成一个间隔槽442。
第一导电层480可以是透明导电层,可以具备导电性和光学透过性。第一导电层480可以是氧化铟锡(ITO),当然第一导电层480也可以为其他材料,诸如氧化锡(SnO2)或氧化锡锑(ATO)。第一导电层480铺设在第一基层440上,诸如第一导电层480铺设在间隔条424上以及铺设在间隔槽442内。
需要说明的是,第一导电层480的厚度较薄,当第一导电层480铺设在间隔槽442及间隔条424上后,在间隔槽442位置依然是个槽结构。
电致变色条422为多个,电致变色条422的个数可以与间隔槽442的个数相 同,一个电致变色条422可以放置在一个间隔槽442内,或者说相邻两个电致变色条422可以由一个间隔条424间隔开。从而使得电致变色条422和间隔条424位于同一层,电致变色条422和间隔条424可以形成电致变色层420。至少部分电致变色条422可以与第一导电层480电性连接,诸如所有的电致变色条422可以与第一导电层480电性连接。各个电致变色条422可以相互平行、且等间隔设置,各个电致变色条422的形状可以相同,诸如长度相同、宽度相同、高度相同。本申请实施例电致变色条422的宽度和间隔条424的宽度可以相等,可以使得偏光组件400具有更好的偏光作用。需要说明的是,在一些实施例中各个电致变色条的间隔不同也是可以的,诸如显示装置20具有曲面结构时,在曲面结构位置的电致变色条与其他电致变色条的间隔可以不相同。
本申请实施例电致变色条422可以实现电致变色的功能,或者说电致变色条422应用到偏光组件400中具有变色功能。电致变色是指材料的光学属性(如反射率、透光率、吸收率等)在外加电场的作用下发生稳定、可逆的颜色变化的现象。电致变色在外观上表现为材料的颜色和透明度的可逆变化。具有电致变色性能的材料可以称为电致变色材料。电致变色条422可以具有电致变色材料,其可以在电场的作用下发声颜色变化。利用电致变色材料制成的器件可以称为电致变色单元,在此将其称为偏光组件400。
请参阅图5,图5为图4所示偏光组件中电致变色条的结构示意图。电致变色条422可包括层叠设置的变色层4222、电解质层4224和离子存储层4226。
变色层4222是电致变色单元的核心层,也是变色反应的发生层。变色层4222的材料按照类型可分为无机电致变色材料和有机电致变色材料。无机电致变色材料可以是三氧化钨(WO3)或者氧化镍(NiO)。有机电致变色材料主要有聚噻吩类及其衍生物、紫罗精类、四硫富瓦烯、金属酞菁类化合物等。
电解质层4224由特殊的导电材料组成,如包含有高氯酸锂、高氯酸纳等的溶液的液态电解质材料,或者也可以是固态电解质材料。
离子存储层4226在电致变色单元中起到存储电荷的作用,即在变色层材料发生氧化还原反应时存储相应的反离子,以保证整个电致变色单元的电荷平衡。
第二导电层410可以是透明导电层,可以具备导电性和光学透过性。第一 导电层480可以是氧化铟锡(ITO),当然第二导电层410也可以为其他材料,诸如氧化锡(SnO2)或氧化锡锑(ATO)。第二导电层420可以铺设在电致变色条420上。第二导电层420可以与多条电致变色条422电性连接,诸如第二导电层420可以与所有的电致变色条422电性连接。
第二基层460也可以作为偏光组件400的基体结构。第二基层460可以采用透明材料,诸如无色透明玻璃。第二基层460可以铺设在第二导电层410上。
当在两个透明导电层(第一导电层480和第二导电层410)之间加上一定的电压时,电致变色条422的变色层4222的材料在电压作用下发生氧化还原反应,从而发生颜色变化。诸如在两个透明导电层(第一导电层480和第二导电层410)之间加上一定的正压可以使得电致变色条422的变色层4222的材料在电压作用下发生着色反应,在两个透明导电层(第一导电层480和第二导电层410)之间加上一定的反压或短路可以使得电致变色条422的变色层4222的材料发声褪色反应。需要说明的是,当施加反压时,该反压的时间不能过长,避免变色层4222的材料再次发声着色反应。
例如,当两个透明导电层(第一导电层480和第二导电层410)为电致变色条422施加的电压由0V变为1V时,电致变色条422可以由无色透明状态变成具有第一颜色的状态。该第一颜色可以为白色、红色或其他颜色。具体请参阅图6,图6为本申请实施例提供的偏光组件具有第一颜色的状态图。
当两个透明导电层(第一导电层480和第二导电层410)为电致变色条422施加的电压由1V变为0V时,电致变色条422可以由具有第一颜色的状态变成无色透明状态。或者当当两个透明导电层(第一导电层480和第二导电层410)短路时,电致变色条422可以由具有第一颜色的状态变成无色透明状态。具体请参阅图7,图7为本申请实施例提供的偏光组件在透明状态下的状态图。其中,该电压值的变化仅为举例说明,其并不构成对电压值变化的限定。

请参阅图9,图9为图8所示偏光组件中电致变色条的结构示意图。电致变色条422a可包括依次层叠设置的第一导电层4228a、离子存储层4226a、电解质层4224a、变色层4222a及第二导电层4221a。第一导电层4228a可以参阅第一导电层480,第一导电层4228a与第一导电层480的区别在于,一个第一导电层4228a对应一个电致变色条422a,第一导电层480对应所有的电致变色条422。至少部分第一导电层4228a电性连接,诸如所有的第一导电层4228a电性连接。

同样,当在两个透明导电层(第一导电层4228a和第二导电层4221a)之间加上一定的电压时,电致变色条422a的变色层4222a的材料在电压作用下发生氧化还原反应,从而发生颜色变化。诸如在两个透明导电层(第一导电层4228a和第二导电层4221a)之间加上一定的正压可以使得电致变色条422a的变色层4222a的材料在电压作用下发生着色反应,在两个透明导电层(第一导电层4228a和第二导电层4221a)之间加上一定的反压或短路可以使得电致变色条422a的变色层4222a的材料发声褪色反应。当对多条诸如所有的电致变色条422a的两个透明导电层(第一导电层4228a和第二导电层4221a)施加电压时,多条诸如所有的电致变色条422a的状态均会产生变化,具体状态变化可以参阅图6和图7。
本申请实施例多条诸如所有的电致变色条422或者电致变色条422a用于在 显示面板200的显示状态下显示第一颜色,以使得偏光组件400作为显示面板200的线性偏光片,或者说是光栅。诸如显示装置20在接收到显示指令时,显示装置20的控制器件诸如处理器可以控制显示面板200显示画面以处于显示状态,且该显示装置20的控制器件诸如处理器还控制多条诸如所有的电致变色条422或者电致变色条422a显示第一颜色。多条诸如所有的电致变色条422或者电致变色条422a与多条诸如所有的间隔条424或间隔条424a形成有规律的结构以实现偏光作用,具体请参阅图6。
偏光组件400中电致变色条422或电致变色条422a的宽度可以根据需要设置,相邻两个电致变色条422或电致变色条422a之间的宽度也可以根据需要进行设置,即间隔条424或间隔条424a的宽度可以根据需要进行设置。诸如每毫米宽度可以具有几十至几千条电致变色条422或电致变色条422a,以及几十至几千条间隔条424或间隔条424a。
再比如:电致变色条422或电致变色条422a的宽度以及间隔条424或间隔条424a的宽度均可以小于见光波长,诸如电致变色条422或电致变色条422a的宽度以及间隔条424或间隔条424a的宽度均小于380nm至780nm(纳米)。
显示面板200在不显示状态时,即显示装置20处于熄屏状态时,显示装置20的控制器件诸如处理器可以控制多条诸如所有的电致变色条422或者电致变色条422a不显示颜色,以使得电致变色条为无色透明状态,从而可以提高显示装置20的透光率。即电致变色条422或者电致变色条422a用于在显示面板200的非显示状态下不显示颜色。当然,显示面板200在在不显示状态时,电致变色条422或者电致变色条422a也可以显示第一颜色。
需要说明的是,显示装置20的偏光组件400和显示面板200的配合方式并不限于此,诸如偏光组件400可以仅设置在显示面板200的部分显示区域。
请参阅图10,图10为本申请实施例提供的显示面板的另一结构示意图。显示面板200a可以应用于显示装置中。该显示面板200a可以包括相互连接的第一显示区220和第二显示区240,本申请实施例可以将偏光组件400和第二线区240层叠设置,而不将偏光组件400铺设到第一显示区220位置,该第一显示区220可以铺设偏光片。可以理解的是,本申请实施例所限定的偏光组件400在电致 变色条422或422a处于透明状态时具有高透光率,偏光组件400的透光率远大于偏光片的透光率。因此,可以大大提高第二显示区240位置的透光率。
第一显示区220的尺寸或者说显示面积可以大于第二显示区240的尺寸或者说显示面积。诸如,第二显示区240设置在第一显示区220的边缘或者说边角位置。第一显示区220可以作为显示装置20的主显示部分,第二显示区240可以作为显示装置20的辅助显示部分,或者说是功能显示部分。当然,第一显示区220的显示面积也可以等于或小于第二显示区240的显示面积。
本申请实施例可以将第二显示区240的透光率设置大于第一显示区220的透光率。从而在第二显示区240的非显示状态下可以大大提高第二显示区240的透光率,以便于显示装置20在与传感器诸如摄像头等配合时,摄像头可以透过第二显示区240实现信号的传输。需要说明的是,第一显示区220和第二显示区240的尺寸关系并不限于此,诸如第一显示区220和第二显示区240的尺寸相同,再比如,第一显示区220的显示面积小于第二显示区240的显示面积。
为了将第二显示区240的透光率设置大于第一显示区220的透光率,本申请实施例可以将显示装置20中用来驱动第二显示区240的驱动单元诸如薄膜晶体管(TFT)设置在显示装置20的非显示区域,比如设置在显示装置20的侧边或者说是周缘。本申请实施例可以将第二显示区240中像素的排布相比第一显示区220中像素的排布更加稀疏,即第二显示区240中像素的分布密度小于第一显示区220中像素的分布密度,以减少像素、布线及电路。本申请实施例可以将第二显示区240中像素的尺寸设置大于第一显示区220中像素的尺寸,以减少像素、布线及电路。本申请实施例第二显示区240的内部走线可以采用透光材料,诸如氧化铟锡,以提高第二显示区240的透光率。
可以理解的是,以上仅为本申请将第二显示区240的透光率设置大于第一显示区220的透光率的举例说明,本申请实施例将第二显示区240的透光率设置大于第一显示区220的透光率的方式并不局限于此。
触控面板600可以包括导电电容触摸传感器电极层或者其他触摸传感器部件(例如,电阻触摸传感器部件、声学触摸传感器部件、基于力的触摸传感器 部件、基于光的触摸传感器部件等)。触控面板600可以起到触控的功能。需要说明的是,本申请实施例显示装置20也可以不包括触控面板600。
盖板800可以盖设在触控面板600或偏光组件400上,诸如盖板800盖设在触控面板600上。盖板800可以通过胶层与触控面板600粘接固定。盖板800可以为透明玻璃层、透光塑料、蓝宝石、或其他透明电介质层来保护触控面板600。胶层可以采用透明材料诸如OCA胶。
本申请实施例显示装置20可以应用于电子设备中。
请参阅图11,图11为本申请实施例提供的电子设备的结构示意图。电子设备2可以包括显示装置20、壳体40和传感器60。
显示装置20可参阅图1至图9及相关描述,在此不再赘述。显示装置20可以固定在壳体40上,壳体40可由塑料、玻璃、陶瓷、纤维复合材料、金属(例如,不锈钢、铝等)、其他合适的材料、或这些材料的任意两种或更多种的组合形成。壳体40可使用一体式配置形成,在该一体式配置中,一些或全部壳体40被加工或模制成单一结构,或者可使用多个结构(例如,内框架结构、形成外部外壳表面的一种或多种结构等)形成。
传感器60可以设置在壳体40上,诸如传感器60设置在显示装置20和壳体40之间,传感器60可以透过显示面板200、偏光组件400或偏光组件400a、触控面板600及盖板800传输信号。传感器60也可以仅透过显示面板200、偏光组件400或偏光组件400a及盖板800传输信号。偏光组件400或偏光组件400a可以铺设在显示面板200的整个显示区域,从而显示装置20的各个位置的透光率均有所提升,在显示装置20的下方设置传感器60可以提高传感器60透过显示装置20传输信号的性能。
比如:电致变色条422或电致变色条422a在显示面板200不显示画面时,可以不显示颜色,从而使得电致变色条422或电致变色条422a为无色透明状态,进而使得偏光组件400整体呈无色透明状态,诸如图7所示的状态。传感器60透过显示面板200和偏光组件400传输信号。
电子设备2可以通过处理器进行控制,诸如电子设备2的处理器分别与传感器60、显示面板200及偏光组件400或偏光组件400a电性连接,电子设备2的处 理器在接收到显示指令时,其可以基于显示指令控制显示面板200处于显示状态,同时还可以控制电致变色条422或电致变色条422a显示第一颜色。此时,电子设备2的处理器可以控制传感器60处于不工作状态。而当电子设备2的处理器接收到传输指令时,电子设备2的处理器可以根据传输指令控制显示面板200处于非显示状态,同时可以控制电致变色条422或电致变色条422a不显示颜色,以及控制传感器60透过显示面板200和偏光组件400或偏光组件400a传输信号。由于偏光组件400或偏光组件400a处于无色透明状态,从而就大大提高传感器60传输信号的质量。
其中,传感器60可以包括摄像传感器、指纹传感器、环境光传感器等中的一种或多种。
需要说明的是,电子设备的显示面板也可以为如图10所示的显示面板。
请参阅图12,图12为本申请实施例提供的电子设备的另一结构示意图。电子设备2a可以包括显示装置、壳体40和传感器60。其中,壳体40可以参阅图11及相关内容,传感器60可以参阅图11及相关内容,在此不再赘述。
显示装置可以包括显示面板200a和偏光组件,显示面板200a可以参阅图10及相关内容,偏光组件可以参阅图2至9及相关内容,即偏光组件可以是偏光组件400,也可以是偏光组件400a。
本申请实施例传感器60可以透过第二显示区240传输信号。电子设备2a可以通过处理器进行控制,诸如电子设备2的处理器分别与传感器60、显示面板200a及偏光组件400或偏光组件400a电性连接,电子设备2a的处理器在接收到显示指令时,其可以基于显示指令控制显示面板200a处于显示状态,同时还可以控制电致变色条422或电致变色条422a显示第一颜色。此时,电子设备2a的处理器可以控制传感器60处于不工作状态。而当电子设备2a的处理器接收到传输指令时,处理器可以根据传输指令控制显示面板200a处于非显示状态,同时可以控制电致变色条422或电致变色条422a不显示颜色,以及控制传感器60透过第二显示区240和偏光组件400或偏光组件400a传输信号。由于偏光组件400或偏光组件400a处于无色透明状态,从而就大大提高传感器60传输信号的质量。
以上对本申请实施例提供的显示装置和电子设备进行了详细介绍。本文中 应用了具体个例对本申请的原理及实施方式进行了阐述,以上实施例的说明只是用于帮助理解本申请。同时,对于本领域的技术人员,依据本申请的思想,在具体实施方式及应用范围上均会有改变之处,综上所述,本说明书内容不应理解为对本申请的限制。
