Description

彩膜基板、显示面板和显示装置
技术领域
本发明涉及显示技术领域,尤其涉及一种彩膜基板、一种包括该彩膜基板的显示面板和一种包括该显示面板的显示装置。
背景技术
在现有技术中,有源矩阵有机发光二极管(AMOLED)具有反应速度较快、对比度更高、视角较广等特点,倍受人们的青睐。现今主流的有机发光二极管(OLED)产品中,主要有两种制备方式:一种是以三星为代表的小尺寸有机发光二极管(OLED)显示屏,主要利用精细式掩膜板(fine mask)制作出能发出蓝色,红色,绿色的子像素来实现彩色显示;另一种是以LG为代表的大尺寸有机发光二极管(OLED)显示屏,主要利用开放式掩膜板(openmask)制作出发出白光的有机发光二极管(OLED)器件,随后利用WRGB彩膜来实现彩色显示。其中W像素的设计是为了在具体显示中对亮度的一个补偿,从而能够增加有机发光二极管(OLED)的使用寿命。
而在后一种有机发光二极管(OLED)显示器件的使用过程中,存在一个普遍的问题:由于现有的彩膜基板中,其子像素内的色阻块多由树脂材料等制成,不能满足一些场合的需求,适用范围有限。所以,需要一种新的彩膜基板来解决现有技术中存在的上述问题。

图1为本发明提供的一种彩膜基板的结构示意图;
图2为本发明提供的通过导电层连接的色阻块的结构示意图。
其中,11、衬底基板;12、像素单元;131、由电致变色材料制成的色阻块;132、红色色阻块;133、蓝色色阻块;134、绿色色阻块;135、导电部。
具体实施方式
以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是,此处所描述的具体实施方式仅用于说明和解释本发明,并不用于限制本发明。
作为本发明的第一个方面,如图1所示,提供一种彩膜基板,所述彩膜基板包括衬底基板11,优选地,衬底基板11可以为玻璃基板,衬底基板11被划分为多个像素单元12,每个像素单元12都包括多个子像素单元,每个子像素单元内设置有一个色阻块,其中,每个像素单元12的多个子像素单元中的至少一个色阻块是由电致变色材料制成的。
在本发明中,可以向由电致变色材料制成的色阻块提供控制电压,使得该色阻块呈现预定的颜色,从而可以使得透过所述色阻块的光呈现预定的颜色,进而可以实现显示装置的彩色显示。
可以理解的是,所述电致变色材料是指材料的光学属性(如反射率、透过率、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,在外观上表现为颜色和透明度的可逆变化,具有电致变色性能的材料可称为电致变色材料。
本领域技术人员容易理解的是,为了使得像素单元能够显示不同的颜色,作为本发明的一种实施方式,在显示时,不同色阻块的颜色是不同的。在本发明的一种实施方式中,一个像素单元可以包括三个子像素单元,在显示时,三个子像素单元中的色阻块可以分别为红色色阻块、绿色色阻块和蓝色色阻块。三个色阻块可以均由电致变色材料制成,或者,三个色阻块中的任意一个或者任意两个可以由电致变色材料制成。
在本发明的另一种实施方式中,一个像素单元可以包括四个子像素单元,在显示时,四个子像素单元中的色阻块可以分别是红色色阻块、绿色色阻块、蓝色色阻块和补充色阻块(可以是黄色色阻块或者其他颜色的色阻块)。
本领域技术人员还容易理解的是,不同颜色的光线衰减的速度是不同的。在显示图像时,从不同子像素单元出射的光颜色不同。为了使得不同距离处观看到的图像均不失真,优选地,每个所述像素单元的多个所述子像素单元中的一个色阻块由电致变色材料制成,当该由电致变色材料制成的色阻块接收到控制电压时,由所述电致变色材料制成的色阻块的颜色与透过所述像素单元中的其余多个所述子像素单元的色阻块的光线中衰减最快的子像素单元的色阻块的颜色相同。
假定一个像素单元中颜色X的光线衰减速度最快,相应地,电致变色材料制成的色阻块在接收到控制电压后的颜色也是颜色X。在显示时,一个像素单元中具有两个发出X颜色光的子像素单元,从而可以抵消颜色X的光线衰减速度过快带来的弊端,从而可以使得在不同距离处看到的图像均是不失真的,即,无论在什么距离处均能够看到颜色真实的图像。
可以理解的是,也可以选择像素单元12的多个子像素单元中的两种或两种以上的不同颜色的所述色阻块使用所述电致变色材料制成,这样可以针对像素单元12的其余多个子像素单元中的两种或两种以上不同颜色的色阻块在光线透过后光线颜色的衰减进行补偿,以使得液晶显示器的显示颜色比较均匀。
作为一种更优选地实施方式,由上文可知,如图1所示,当每个像素单元12的多个子像素单元中的一个所述色阻块使用所述电致变色材料制成时,除了该由所述电致变色材料制成的色阻块131外,该像素单元12的多个子像素单元中的其余所述色阻块还可以包括红色色阻块132、蓝色色阻块133和绿色色阻块134,由所述电致变色材料制成的色阻块131在接收到所述控制电压后的颜色变为蓝色。为了降低成本,红色色阻块132、蓝色色阻块133和绿色色阻块134均由树脂材料制成。
透过红色色阻块132的光线为红光,透过蓝色色阻块133的光线为蓝光,透过绿色色阻块134的光线为滤光。本领域技术人员容易理解的是,在红光、蓝光和绿光三种颜色的光线中,蓝光的衰减速度最快。由于显示时电致变色材料制成的色阻块131为蓝色,因此,在一个像素单元中,两个子像素单元发蓝光,增加了蓝光的亮度,从而可以抵消蓝光因衰减速度过快而造成的颜色失真。
还可以理解的是,在一个像素单元12的子像素单元中,该由所述电致变色材料制成的色阻块131在施加控制电压前,由所述电致变色材料制成的色阻块131的颜色可以为白色。
需要说明的是,图1和图2中所示出的色阻块的颜色仅是示例性的,不仅限于上述所述红色、绿色和蓝色,还可以是其它颜色,如黄色等等,可以根据需要进行选择。另外,可以通过调节所述控制电压的大小来实现对光线透过所述由电致变色材料制成的色阻块后的光线颜色的深浅。
作为一种更优选地实施方式,所述电致变色材料包括无机电致变色材料和有机电致变色材料,由于无机电致变色材料中的WO3相对于其他电致变色材料有较高的光学调节能力和较好的电致变色稳定性,所以本发明优选地所述电致变色材料包括WO3材料。另外,WO3材料还具有价格便宜的优势。
具体地,本发明所述电致变色材料选用WO3材料后,在施加所述控制电压达到毫伏级别时,透过由所述WO3材料制成的色阻块131后的光线的颜色为蓝色。
作为另一种优选地实施方式,一个所述彩膜基板中有多个像素单元12,在一个像素单元12中有多个子像素单元,每个子像素单元中设置一个所述色阻块,如果将像素单元12中的多个由所述电致变色材料制成的色阻块131设置在同行但不同列的位置上,为了便于向由电致变色材料制成的色阻块131施加控制电压,优选地,如图2所示,所述彩膜基板还可以包括导电层,该导电层包括多个导电部135,一个导电部将位于同一列的相邻两个由电致变色材料制成的色阻块131电连接。从图2中可以看出,位于同一列的色阻块131是串联的。
在本发明中,对导电部135的材料并没有具体要求,只要能够将相邻的两个电致变色材料制成的色阻块131电连接即可。例如,可以利用金属材料制成导电部135,或者,可以利用透明电极材料制成导电部135。作为本发明的一种优选实施方式,可以利用金属材料(例如,金属铝)制成导电部135。
需要说明的是,由于在所述彩膜基板上还有其他导线,所以在设置导电层135时需要避开所述彩膜基板上的其他导线。
具体地,在衬底基板11上形成所述色阻块时,可以先通过磁控溅射的方式在衬底基板11上形成由所述电致变色材料制成的色阻块131,然后再选用导电材料铝制成的导电部135将位于同一列但不同行的由所述电致变色材料制成的色阻块131串联起来,也可以先在同行但不同列的方向上设置导电部135,然后采用磁控溅射的方式在该同列方向上形成由所述电致变色材料制成的色阻块131。最后再通过光刻的方式形成其余色阻块,如形成红色色阻块132、蓝色色阻块133和绿色色阻块134等。
可以理解的是,在对所述彩膜基板的制备过程中,像素单元12中的多个子像素单元的排列方式不做限定,例如可以多行多列设置,也可以并排设置,对于子像素单元内的所述色阻块的尺寸也不做具体限定,这些都可以根据自己的需要来进行设计。
本发明提供的彩膜基板,通过设置由电致变色材料制成的色阻块使得在该色阻块施加控制电压后,与像素单元中的其余多个子像素单元的色阻块的光线中衰减最快的子像素单元的色阻块颜色相同,实现了对透过衰减快的色阻块后光线颜色的补偿。本发明这种对光线颜色的补偿方法,可以使得不同距离处均能够看到颜色真实的图像,提高了用户体验。
作为本发明的第二个方面,提供一种显示面板,所述显示面板包括上文所述彩膜基板。
在本发明中,对显示面板的具体类型并不做特殊的限制,例如,所述显示面板可以是液晶显示面板,也可以是OLED显示面板。
作为本发明的第三个方面,还提供一种显示装置,所述显示装置包括前文所述显示面板。
所述显示装置可以是手机、电视、平板电脑、导航仪等电子设备。
作为一种优选地实施方式,本发明所述显示装置还包括控制模块,所述控制模块与所述彩膜基板连接,用于为所述彩膜基板中的由所述电致变色材料制成的所述色阻块提供所述控制电压。所述控制模块还可以通过调节所述控制电压的大小以调节透过由所述电致变色材料制成的所述色阻块的光线颜色的深浅。
优选地,当所述电致变色材料为WO3材料时,所述控制模块提供的所述控制电压为毫伏级,此时可以使得透过由WO3材料制成的所述色阻块的光线颜色为蓝色,即可以使得所述显示装置中透过由WO3材料制成的所述色阻块的光发蓝色光。
本发明提供的显示装置,通过设置具有由电致变色材料制成的色阻块的彩膜基板以及设置为该彩膜基板提供控制电压的控制模块实现了显示装置中透过由电致变色材料制成的色阻块的光的颜色发生变化,对显示装置中透过色阻块后光线衰减最快的光线颜色进行补偿,可以使得不同距离处均能够看到颜色真实的图像,提高了用户体验。
可以理解的是,以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式,然而本发明并不局限于此。对于本领域内的普通技术人员而言,在不脱离本发明的精神和实质的情况下,可以做出各种变型和改进,这些变型和改进也视为本发明的保护范围。
